The Colonization of Space – Gerard K. O’Neill, Physics …

Posted: October 19, 2015 at 4:43 am

Careful engineering and cost analysis shows we can build pleasant, self-sufficient dwelling places in space within the next two decades, solving many of Earth's problems.

New ideas are controversial when they challenge orthodoxy, but orthodoxy changes with time, often surprisingly fast. It is orthodox, for example, to believe that Earth is the only practical habitat for Man, and that the human race is close to its ultimate size limits. But I believe we have now reached the point where we can, if we so choose, build new habitats far more comfortable, productive and attractive than is most of Earth.

Although thoughts about migration into space are as old as science fiction, the technical basis for serious calculation did not exist until the late 1960's. In addition, a mental "hangup" the fixed idea of planets as colony sites appears to have trapped nearly everyone who has considered the problem, including, curiously enough, almost all science-fiction writers. In recent months I learned that the space pioneer Konstantin Tsiolkowsky, in his dreams of the future, was one of the first to escape that hangup.

By chance, and initially almost as a joke, I began some calculations on the problem in 1969, at first as an exercise for the most ambitious students in an introductory physics course. As sometimes happens in the hard sciences, what began as a joke had to be taken more seriously when the numbers began to come out right. There followed several years of frustrating attempts to get these studies published.

Friends advised that I take my ideas "to the people" in the form of physics lectures at universities. The positive response (especially from students) encouraged me to dig harder for the answers to questions about meteoroid damage, agricultural productivity, materials sources, economics and other topics. The results of that study indicate that

How can colonization take place? It is possible even with existing technology, if done in the most efficient ways. New methods are needed, but none goes beyond the range of present-day knowledge. The challenge is to bring the goal of space colonization into economic feasibility now, and the key is to treat the region beyond Earth not as a void but as a culture medium, rich in matter and energy. To live normally, people need energy, air, water, land and gravity. In space, solar energy is dependable and convenient to use; the Moon and asteroid belt can supply the needed materials, and rotational acceleration can substitute for Earth's gravity.

Space exploration so far, like Antarctic exploration before it, has consisted of short-term scientific expeditions, wholly dependent for survival on supplies brought from home. If, in contrast, we use the matter and energy available in space to colonize and build, we can achieve great productivity of food and material goods. Then, in a time short enough to be useful, the exponential growth of colonies can reach the point at which the colonies can be of great benefit to the entire human race.

To show that we are technically able to begin such a development now, this discussion will be limited to the technology of the 1970's, assuming only those structural materials that already exist. Within a development that may span 100 years, this assumption is unrealistically conservative. We shall look at the individual space communities their structure and appearance and the activities possible for their inhabitants, their relation to the space around them, sources of food, travel between communities as well as to Earth, the economics of the colonies and plans for their growth. As is usual in physics, it is valuable to consider limiting cases; for this study, the limits are an eventual full-size space community on a scale established by the strength of materials, and a first model, for which cost estimates can reasonably be made. The goals of the proposal will be clearer if we first discuss the large community.

A cylindrical habitat

The geometry of each space community is fairly closely defined if all of the following conditions are required: normal gravity, normal day and night cycle, natural sunlight, an earthlike appearence, efficient use of solar power and of materials. The most effective geometry satisfying all of these conditions appears to be a pair of cylinders. The economics of efficient use of materials tends to limit their size to about four miles in diameter, and perhaps about 16 miles in length. (See figure 1.) In these cylinder pairs, the entire land area is devoted to living space, parkland and forest, with lakes, rivers, grass, trees, animals and birds, an environment like most attractive parts of Earth; agriculture is carried on elsewhere. The circumference is divided into alternating strips of land area "valleys") and window area ("solars"). The rotation period is two minutes, and the cylinder axes are always pointed toward the Sun.

Figure 1. Section of a space-community main cylinder (top). The circumference is divided into alternating strips of land area (valleys) and window area (solars). Although the space-community valleys offer new landscaping opportunities and architectural possibilities, it is reassuring to note that certain Earth features can be recreated: the side view of a cylinder end cap (bottom) includes a mountain profile taken from an aerial photograph of a section of the Grand Teton range in Wyoming.

Because the Moon is a rich source both of titanium and of aluminum, it is likely that these metals will be used extensively in the colonies. For conservatism, though, the calculation of the cylinder structure has been based on the use of steel cables, to form "longerons" (longitudinal members carrying the atmospheric forces on the end caps) and circumferential bands (carrying the atmospheric force and the spin-induced weights of the ground, of the longerons and of themselves). For details of this calculation and the assumptions it includes, see the box [below]. The steel cables are bunched to form a coarse mesh in the window areas. The bands there subtend a visual angle of 2.3 x10-4 radians, about equal to the diffraction limit for the sunlight-adapted human eye, and so are nearly invisible. The windows themselves are of glass or plastic, subdivided into small panels.

Steel structure

For the structure, steel cables are assumed to be formed into longerons (average thickness rL) and circular bands (average thickness rB). The value of rL required is

rL = Ro/2T

where R is the cylinder radius, o the atmospheric pressure and T the tension. For land density L and depth xL, and bands of density F, the total equivalent internal pressure pT is

pT = o + LxLg + FrBg + FrLg

To solve for pT we note that

rB = pTR/T

so that

pT = (o + gLxL + gFR/T)/(1 -gFR/T)

For an average soil depth of 150 cm, with an average density of 1.5 gm per cc,

po = gLxL = 1.23 x 105 newtons/m2

To arrive at a conservative value for T, we note that half a century ago, the working stress for suspension-bridge cables was 70,000 to 80,000 pounds per square inch [ref 1]. At that time, D. B. Steinman [ref 1] argued for the use of stresses over 100,000 psi. If we use 1920's steels, hardened to bring the yield point to 90% of the ultimate strength, and work at 75% of the yield point, the working stress can be 152,000 psi. If we take T as 150,000 psi and R as 3200 meters, the averaged surface mass density is 7.5 tons per square meter.

In the window (solar) areas, the longerons can be 0.8-meter cables in stacks of four at 14-meter intervals. The bands can be in the same arrangement, but with a 1.5-meter diameter, and the mesh transparency will then be 84%. Considerably larger values of R would result from the extensive use of titanium in the structure, together with a thinner layer of earth.

There is no sharp upper limit on the size of a space-community cylinder; with increasing size, though, a larger fraction of the total mass is in the form of supporting cables. The figure 3200 meters for radius R is somewhat arbitrary. Economy would favor a smaller size; use of high-strength materials, or a strong desire for an even more earthlike environment, would favor a larger. Independent of size, the apparent gravity is earth-normal, and the air composition as well as the atmospheric pressure are those of sea level on Earth. For R equal to 3200 meters, the atmospheric depth is that of an Earth location at 3300 meters above sea level, an altitude where the sky is blue and the climate habitable: At any radius r within the cylinder we have

p = poe-a(R2-r2)

where

a gpo/2Rpo = (1/2R)(1.2 x10-4/meter)

The length of a day in each community is controlled by opening and closing the main mirrors that rotate with the cylinders. The length of day then sets the average temperature and seasonal variation within the cylinder. Each cylinder can be thought of as a heat sink equivalent to 3 x108 tons of water; for complete heat exchange, the warnup rate in full daylight would be about 0.7 deg C per hour. As on Earth, the true warmup rate is higher because the ground more than a few centimeters below the surface does not follow the diurnal variation.

Bird and animal species that are endangered on Earth by agricultural and industrial chemical residues may find havens for growth in the space colonies, where insecticides are unnecessary, agricultural areas are physically separate from living areas, and industry has unlimited energy for recycling.

As we can see in figure 1, it is possible to recreate certain Earth features: the mountain profile is taken from an arieal photograph of a section of the Grand Teton range in Wyoming. The calculated cloud base heights as seen in the figure are typical of summer weather on Earth: For a dry adiabatic lapse rate of 3.1 deg per 300 meters and a dew-point lapse rate of 0.56 deg per 300 meters, relative humidity and a temperature range between zero and 32C, the cloud base heights range between 1100 and 1400 meters.

Environmental control

The agricultural areas are separate from the living areas, and each one has the best climate for the particular crop it is to grow. Gravity, atmosphere and insolation are earthlike in most agricultural cylinders, but there is no attempt there to simulate an earthlike appearence. Selected seeds in a sterile, isolated environment initiate growth, so that no insecticides or pesticides are needed. (The evolution time for infectious organism is long, and resterilization of a contaminated agricultural cylinder by heating would not be difficult.) All food can be fresh, because it is grown only 20 miles from the point of use. The agricultural cylinders can be evenly distributed in seasonal phase, so that at any given time several of them are at the right month for harvesting any desired crop.

Figure 2 shows side and end views of a space community as a complete ecosystem. The main mirrors are made of aluminum foil and are planar. Moving these mirrors varies the angle at which sunlight hits the valleys (controlling the diurnal cycle), and the Sun appears motionless in the sky, as it does on Earth. The solar power stations, which consist of paraboloidal mirrors, boiler tubes and conventional steam-turbine electric generators, can provide the community with sufficient power, easily up to ten times the power per person now used (10 kw) in highly industrialized regions [ref 2].For such energy-rich conditions (120 kw per person) the power needed for a cylinder housing 100,000 people is 12,000 megawatts: The solar power incident on a cylinder end cap is 36,000 megawatts, adequate if the thermal efficiency is 33%. Extra power plants near the agricultural ring would be needed for higher population density. Waste heat is sent into space by infrared radiators of low directionality.

Figure 2. Space community as a whole is seen in side (top) and end (bottom) views For the end view, 37 of the 72 agricultural cylinders in a ring are shown; the ring does not rotate as a whole. Note the lines of symmetry in both sections of the figure.

The communities are protected from cosmic rays by the depth of the atmosphere and by the land and steel supporting structure, the bands and longerons being distributed where visual transparency is unnecessary. Meteoroid damage should not be a serious danger. Most meteoroids are of cometary rather than asteroidal origin and are dust conglomerates, possibly bound by frozen gases [ref 3]; a typical meteoroid is more like a snowball than like a rock. Spacecraft sensors have collected abundant and consistent data on meteoroids in the range 10-6 to 1 gram, and the Apollo lunar seismic network is believed to have 100% detection efficiency for meteoroids [ref 4] above 10 kg: Data from these sources are consistent with a single distribution law.

The Prairie Network sky-camera data [ref 5], after substantial correction for assumed luminous efficiency, agree with data from the National Aeronautics and Space Administration for 10-gm meteoroids. The spacecraft and seismic data indicate a mean interval of about one-million years for a strike by a heavy (one ton) meteoroid on a space community of cross section 1000 square kilometers. Even such a strike should produce only local damage if the structure is well designed. For 100-gram meteoroids, the mean interval for a strike is about three years. From the combined viewpoints of frequency and of momentum carried, the size range from one to ten grams may need the most care in window design and repair methods. For total breakage of one window panel, Daniel Villani at Princeton has calculated a leakdown time of about 300 years. Meteoroid-damage control is, then, a matter of sensing and of regular minor repair rather than of sudden emergencies.

Axial rotation and transport

A key element in the design of the space colony is the coupling of two cylinders by a tension cable and a compression tower to form a system that has zero axial angular momentum and is therefore able to maintain its axis pointed toward the Sun without the use of thrusters. The force and torque diagram for this arrangement is seen in figure 3. To accelerate the cylinders up to the required rotational speed, static torque is transmitted through the compression framework that joins the two cylinders of a pair. For a spin-up time of three years, a constant 560,000 horsepower is needed; this is 3% of the generator capacity of a cylinder. After spinup, the same motors can provide maintenance power for frictional losses and for attitude control about the spin axis. Each cylinder's angular momentum is 1.5 x1018 kg2 rad per sec; the torque needed to precess this angular momentum once each year is 3 x1011 newton meters, corresponding to a constant force of 1200 tons on a 26-km lever arm.

The phase difference of seasons between the two cylinders permits "seasonal counterpoint," midsummer in one cylinder during midwinter in the other. Travel between the two requires no power and only nine minutes of time. They are only 90 km apart, and engineless vehicles can unlock from the outer surface of one cylinder at a preset time, move in free flight with the tangential velocity (180 meters per sec or 400 miles per hour) and lock on to the other cylinder at zero relative velocity.

Travel between communities can also be carried out with simple engineless vehicles, accelerated in a computed direction by a stationary cable-pulling electric motor and decelerated by an arresting cable at the destination. The "cable-car" vehicles for such free flight need no fuel, no complex maintenance nor a highly trained crew, and should be inexpensive. Vehicle speeds permit travel among a total population larger than that of Earth within flight times of seven hours. (I have here assumed communities spaced at 200-km intervals, so that the maximum dimension of a planar cluster housing 4 billion people is 29,000 km. For a vehicle with acceleration 1g and the required travel time of seven hours, the acceleration length is 66 km.) With no need for aerodynamic design, the vehicles can be far more roomy and comfortable than the typical earthbound commercial jet.

Life in the colonies

The key statements so far have been based on known facts, on calculations that can be checked and on technology whose costs can be estimated realistically. The discussion, however, would be sterile without some speculations that must, of course, be consistent with the known facts.

With an abundance of food and clean electrical energy, controlled climates and temperate weather, living conditions in the colonies should be much more pleasant than in most places on Earth. For the 20-mile distances of the cylinder interiors, bicycles and lowspeed electric vehicles are adequate. Fuel-burning cars, powered aircraft and combustion heating are not needed; therefore, no smog. For external travel, the simplicity of engineless, pilotless vehicles probably means that individuals and families will be easily able to afford private space vehicles for low-cost travel to far distant communities with diverse cultures and languages. The "recreational vehicles" of the colonial age are therefore likely to be simple spacecraft, consisting of well furnished pressure shells with little complexity beyond an oxygen supply and with much the same arrangement of kitchen facilities and living space as are found today in our travelling homes.

All Earth sports, as well as new ones, are possible in the communities. Skiing, sailing, mountain climbing (with the gravity decreasing linearly as the altitude increases) and soaring are examples. As an enthusiastic glider pilot, I have checked the question of thermal scales: The soaring pilots of the colonial age should find sufficient atmospheric instability to provide them with lift. At high altitudes, man-powered flight a nearly impossible dream on Earth becomes easy. A special, slowly rotating agricultural cylinder with water and fish can have gravity 10-2 or 10-3 times that on Earth for skin diving free of pressure-equalization problems. Noisy or polluting sports, such as auto racing, can easily be carried out in one of the cylinders of the external ring.

The self-sufficiency of space communities probably has a strong effect on government. A community of 200,000 people, eager to preserve its own culture and language, can even choose to remain largely isolated. Free, diverse social experimentation could thrive in such a protected, self-sufficient environment.

If we drop our limitation to present technology, the size of a community could be larger. One foreseeable development is the use of near-frictionless (for example, magnetic) bearings between a rotating cylinder and its supporting structure, which need not be spun. For eight tons per square meter of surface density and a tensile strength of 300,000 psi, R would be 16 km, the total area would 50,000 km2, and the population would be between five million (low density) and 700 million (the ecological limit, the maximum population that can be supported).

In Table 1 we see my estimate of the earliest possible schedule for space colonization, beginning with a model community in the late 1980's. From about the year 2014, I assume a doubling time of six years for the colonies; that is, the workforce of a "parent" colony could build a "daughter" colony within that time. In making these estimates I have calculated that the first model community would require a construction effort of 42 tons per man-year, comparable to the effort for large-scale bridge building on Earth. Full-size communities at high population density require 50 tons per man-year, and up to 5000 tons per man-year for low population density. For comparison, automated mining and shipping in Australia now reaches 200 tons per man-year averaged over a town [ref 6].

In the long run, space-colony construction is ideally suited to automation. A colony's structure consists mainly of cables, fittings and window panels of standard modular form in a pattern repeated thousands of times. The assembly takes place in a zerogravity environment free of the vagaries of weather. By the time that the colonies are evolving to low population density, therefore, I suspect that very few people will be involved in their construction. Most of the workforce will probably be occupied in architecture, landscaping, forestry, zoological planning, botany and other activities that are nonrepetitive and require a sense of art and beauty.

Our new options

It is important to realize the enormous power of the space-colonization technique. If we begin to use it soon enough, and if we employ it wisely, at least five of the most serious problems now facing the world can be solved without recourse to repression: bringing every human being up to a living standard now enjoyed only by the most fortunate; protecting the biosphere from damage caused by transportation and industrial pollution; finding high-quality living space for a world population that is doubling every 35 years; finding clean, practical energy sources; preventing overload of Earth's heat balance.

I hesitate somewhat to claim for space-colonization the ability to solve one other problem, one of the most agonizing of all: the pain and destruction caused by territorial wars. Cynics are sure that humanity will always choose savagery even when territorial pressures are much reduced. Certainly the maniacal wars of conquest have not been basically territorial. Yet I am more hopeful; I believe we have begun to learn a little bit in the past few decades. The history of the past 30 years suggests that warfare in the nuclear age is strongly, although not wholly, motivated by territorial conflicts; battles over limited, nonextendable pieces of land.

From the viewpoint of international arms control, two reasons for hope come to mind. We already have an international treaty banning nuclear weapons from space, and the colonies can obtain all the energy they could ever need from clean solar power, so the temptations presented by nuclear-reactor byproducts need not exist in the space communities.

To illustrate the power of space-colonization in a specific, calculable situation, we trace the evolution of a worst-case example: Suppose the present population-increase rate were to continue on Earth and in the space colonies. In that case the total human population would increase 20,000-fold in a little over 500 years. Space-colonization would absorb even so huge a growth, as we shall see from our calculations.

The total volume of material needed in a full-size community is 1.4 x109 cubic meters, and the material available in the asteroid belt (from which the later communities will be built) is estimated to be 4 x1017 cubic meters, about one twenty-five hundredth the volume of Earth. For a present world population of 3.9 x 109 people and a growth rate [ref 7] of 1.98% per year (the 1965-71 average), the asteroidal material would last 500 years, corresponding to a 20,000-fold population increase at low population density.

In figure 4, we see the development of this worst-case problem. To hasten the solution of that problem, the initial space community population density is taken as the ecological limit; the maximum number of people that can be supported with food grown within the communities, with conventional agriculture. Richard Bradfield has grown enough to feed 72 people per hectare by the techniques of double planting and multiple cropping, and with the use of cuttings for livestock feed. These results [ref 8], as published and also as described to me by Bradfield, were obtained in the Phillipines, which has only a nine-month growing season and less than ideal weather conditions. Calculations based on his figures, but assuming an ideal twelve-month season, indicate that the colonies should be able to support 143 people per hectare with a diet of 3000 calories, 52 grams of usable protein and 4.3 pounds of total food per person per day [ref 9]. Much of the protein would come from poultry and pork. The two main cylinders of Model 1 should then be able to support up to 10,800 people, and the corresponding ecological limit for a full-size community would be 20 million people. At this limit, all the colonists would have a high standard of living, but in apartment-house living conditions, looking out over farmland. For a community limit of 13-million people, the main cylinders could be kept free of agriculture.

By about 2050, then, figure 4 indicates that emigration to the colonies could reverse the rise in Earth's population, and that the acceleration of the solution could be dramatically fast: Within less than 30 years, Earth's population could be reduced from a peak of 16.5 billion people to whatever stable value is desired. I have suggested 1.2 billion as a possible optimum; it corresponds to the year 1910 in Earth history. The reduction in population density in the space communities could be equally rapid, and within another 40 years new construction could thin out the communities to a stable density of 1.43 people per hectare, about one hundredth of the ecological limit. The total land area in the colonies would then be more than three times that of Earth.

We can hope that, in contrast to this worst-case example, some progress toward zero population growth [ref 10] will be made in the next 75 years. Any such progress will hasten the solution, reduce Earth's population peak, and hasten the day when the population densities on Earth as well as in the colonies can be reduced to an optimum value.

Building the first colony

A responsible proposal to begin the construction of the first colony must be based on a demonstration, in some detail, of one workable plan with realistic cost estimates. I emphasize two points about any such plan: The details presented should be thought of simply as an existence proof of feasibility; and many variations are possible. The optimum design and course of action can only be decided on after study and consultation among experts in a number of fields.

The nominal values for the first model colony are taken as: construction force, 2000 people; population, 10,000; total mass, 500,000 tons. When the design and cost analysis are done in detail for the entire enterprise, the need to fit a budget may force some reduction in size. The initial estimates have been aimed at holding the cost equal to that of one project we have already carried through: Apollo. The choice of 10,000 as a target population ensures that, even with some reduction, Model 1 will be large enough to obtain economies of scale and to serve as an effective industrial base for the construction of Model 2. A much reduced colonization project would be little more than a renamed space station, perhaps able to maintain itself but incapable of building the larger models that are necessary if the program is ultimately to support itself. It is an essential feature of the colonization project that Earth should no longer have to support it after the first two or three stages.

Ultimately, colonization could take place in the entire sphere, 3 x 1017 km2 in area, that surrounds the Sun at the distance we have evolved to prefer (the so-called "Dyson sphere"). For the first colony it is probably best to choose a particular point on that sphere, within easy range of both Earth and Moon, not so close as to be eclipsed often, and preferably stable against displacements in all three coordinates. The L4 and L5 Lagrange libration points satisfy all these conditions. They have the further advantage of forming only a very shallow effective-potential well [ref 11].

Earth, Moon, Sun and the colony form a restricted four-body gravitational problem, for which the full solution has only been worked out within the past several years [ref 12].The stable motion is a quasielliptical orbit, of large dimensions, about L5. The maximum excursions in arc and radius are several tenths of the Earth-Moon distance. On the stable orbit there is room for several thousand colonies; a long time will pass before colonization can fill so big an orbit.

Human Resources, Learning, and Leadership: Our Ten …

Posted: at 4:40 am

2014 will be an exciting and challenging year for HR, learning, and talent professionals. (Download our 66 page Predictions Report here.)

Global economic growth will create a new level of competition for people. HR organizations will shift their focus from cost reduction to retention and engagement. Technology will continue to make the world a smaller place, forcing companies to improve their employment brand in every possible way. Data will become a new currency. Leadership will continue to be in short supply. And you, as an HR professional, will have to innovate and adapt to stay ahead.

In this blog I summarize our ten predictions for 2014, detailed in the report linkedhere. This is our tenth year publishing these predictions, and I hope you find them educational and valuable as you plan your strategies for the year ahead.

2014: The Year of the Employee:

Attraction, Retention, and Engagement Will Really Matter

For the first time in nearly a decade, this year you will find the issues of retention, engagement, and "attraction of talent" to be top on your priority list. We are just completing a major global study (Deloitte's Human Capital Trends 2014, coming soon) and found thatthe top two people issues facing organizations in 2014 are leadership and retention. These are the problems we face in a dynamic, growing global economy.

This year the power will shift: high-performing employees will start to exert control. Top people with key skills (engineering, math, life sciences, energy) will be in short supply. Thanks to the US healthcare laws, people will feel more free to change jobs. And companies who can't engage and attract Millenials will lose out.

While there will still be high levels of unemployment in places, generally people have changed their perspectives. They want work which is meaningful, rewarding, and enjoyable. Top performers will seek out career growth. Mid-level staff will strive for leadership development. And you, as an HR organization, will have to compete, adapt, and innovate to stay ahead.

1. Talent, skills, and capability needs become global.

In 2014 key skills will be scarce. Software engineering, energy and life sciences, mathematics and analytics, IT, and other technical skills are in short supply. And unlike prior years, this problem is no longer one of "hiring top people" or "recruiting better than your competition." Now we need to source and locate operations around the world to find the skills we need.

You must expand your sourcing and recruiting to a global level. Locate work where you can best find talent. And build talent networks which attract people around the world.

2. Integrated capability Development Replaces Training.

The "training department" will be renamed "capability development." Companies will find skills short and they will have to build a supply chain for talent. Partner with universities, establish apprentice programs, create developmental assignments, and focus on continuous learning. Companies that focus on continuous learning in 2014 will attract the best and build for the future.

3. Redesign of Performance Management Accelerates.

The old-fashioned performance review is slowly going out the window. In 2014 companies will aggressively redesign their appraisal and evaluation programs to focus on coaching, development, continuous goal alignment, and recognition. The days of "stacked ranking" are slowly going away in today's talent-constrained workplace, to be replaced by a focus on engaging people and helping them perform at extraordinary levels.

4. Redefine engagement: Focus on Passion and the Holistic Work Environment

As one HR manager recently put it, "our employees are no longer looking for a career, they're looking for an experience." Your job in 2014 is to make sure that experience is rewarding, exciting, and empowering.

5. Take Talent Mobility and Career Development Seriously

Talent mobility is with us for good: thanks to tools like LinkedIn, Twitter, and Facebook people can find new jobs in a heartbeat. This means you, as an employer, need to provide internal talent mobility and career growth in your own organization. 2014 is the time to build a "facilitated talent mobility" strategy which includes open access to internal positions, employee assessment tools, interview guides, and leadership values that focus on internal development.

Are your managers paid to "consume talent" or "produce talent?" Remember the best source of skills is within your own organization - if you cannot make internal mobility easy, good people will go elsewhere.

6. Redesign and Reskill the HR Function

Surprise: in our global Human Capital Trends research the need to "Reskill HR" was rated one of the top five challenges in every geography around the world. Why? Because HR itself is changing dramatically and we need to continuously skill our own teams to maintain our relevance and value.

Our new High-Impact HR research, scheduled for launch in early 2014, shows statistically that high-performing companies invest in HR skills development, external intelligence, and specialization. In 2014 if you aren't reinvesting in HR, you'll likely fall behind.

7. Reinvent and Expand Focus on Talent Acquisition

As the economy improves you will need to more aggressively and intelligently source and recruit. The talent acquisition market is the fastest-changing part of HR: new social recruiting, talent networks, BigData, assessment science, and recruiting platforms are being launched every month.

In 2014 organizations will need to integrate their talent acquisition teams, develop a global strategy, and expand their use of analytics, BigData, and social networks. Your employment brand now becomes more strategic than ever - so partner with your VP of Marketing if you haven't already. Today your ability to recruit is directly dependent on your engagement and retention strategy - what your employees experience is what is communicated in the outside world.

8. Continued Explosive Growth in HR Technology and Content Markets

The HR technology and content markets will expand again in 2014. ERP players (Oracle, SAP, Workday, ADP) are all delivering integrated solutions now. IBM, CornerstoneOnDemand, PeopleFluent, SumTotal, and dozens of other fast-growing talent management companies are now offering end-to-end solutions. And most now offer integrated analytics solutions as well.

Mobile apps, MOOCs, expanded use of Twitter, and an explosion in the use of video has created a need to continuously invest in HR technology. In 2014 the theme is "simplify" - understand technology but keep it simple. Employees are already overwhelmed and we need to make these tools and content easy to use. The word for 2014 is "adoption" - make technology easy to use and it will deliver great value.

9. Talent Analytics Comes to Front of the Stage

Talent Analytics is red hot. More than 60% of you are increasing investment in this area and company after company is uncovering new secrets to workforce performance each day. In 2014 you should build a talent analytics center of excellence and invest in the infrastructure, data quality, and integration tools you need. This market is finally here, and companies that excel in talent analytics have improved their recruiting by 2X, leadership pipeline by 3X, and financial performance as well.

10. Innovation Comes to HR. The New Bold, CHRO

One of the top three challenges companies now face is "reskilling their HR team." This points to the issue that HR itself, as a business function, is undergoing radical change. Today's HR organization is no longer judged by its administrative efficiency - it is judged by its ability to acquire, develop, retain, and help manage talent. And more and more HR is being asked to become "Data-Driven" - understand how to best manage people based on real data, not just judgement or good ideas.

As a result of these changes, our research shows a new model for HR emerging - one we call High-Impact HR. In this new world HR professionals are highly trained specialists, they act as consultants, and they operate in "networks of expertise" not just "centers of expertise." And driving this new world is a strong-willed, business-driven CHRO. In 2014 organizations should focus on innovation, new ideas, and leveraging technology to drive value in HR. This demands an integrated team, a focus on skills and capabilities within HR, and strong HR leadership.

Bottom line:

2014 looks to be an exciting and critically important year for Human Resources. The economy will grow, employees will be in charge, and HR's role in business success will be more important than ever.

Chapter 1

Futurism as a Metaphysical Science

It is surprising how little the common perception of futurism has changed since 1967, when Maurizio Calvesi complained about the "reductive general idea of Italian futurism as a simple exaltation of the machine and superficial reproduction of movement."1 Although the futurists did not always agree among themselves on a definition of the movement, they certainly would not have shared a view that reduces futurism to merely materialistic terms.2 If a similarly reductive attitude can already be found in Varse as early as 1917, the reduction of futurism to a materialistic movement within post-World War II art criticism was likely determined, as noted in the introduction, by a need to downplay the uneasy relationship between futurism and fascism.3

Yet futurism was a movement animated by contradictory ideas, constantly oscillating between science and art, the rational and the irrational, future and past, mechanical and spiritual. Indeed, it may well have been these very tensions and frictions that gave futurism its dynamic force.

Defining the futurist movement and analyzing its aesthetic is not an easy task. To the casual observer the futurists seem to present a united front, unified by the charismatic personality of Marinetti, but analysis shows them to have been highly diverse intellectual personalities, each with slightly different opinions and conceptions of life and art and sometimes in open and violent opposition to one another. They may have found themselves (for reasons of convenience, if nothing else, and perhaps sometimes opportunism) under one ideological roof, but individually they maintained autonomous physiognomies and attitudes and peculiarities of their own. It seems, then, impossible to hope to find coherence inside the different poetic positions of the futurists, let alone to formulate an organic presentation with which they would have been satisfied.

Marinetti's work and personality succeeded in maintaining a certain order, at least in the beginning. It is well documented that Marinetti initially subsidized all the initiatives of the movement (including publications and exhibitions), and, like a good impresario, he reserved the right to supervise the work of the other artists of the group, to the point that all the first futurist manifestos unquestionably ran the gauntlet of Marinetti's censorship; this explains their similar tone.4 But in the privacy of living-room discussions or personal correspondence-or anywhere outside Marinetti's public control-the futurists' aesthetic visions diverged synchronically and diachronically; they were in continual growth and in a restless state of becoming, changing along with the shifting alliances within the movement.

Critically the most lucid figure among them was probably Umberto Boccioni. Perhaps for a predisposition of spirit, perhaps because his career lasted for only a brief moment and almost did not leave him time to conclude a cycle of thought, Boccioni was one of the very few futurists to produce a volume that presented his poetics systematically.5

The other exception was Luigi Russolo. Although he was not as socially exuberant as Boccioni was, his thought was characterized by a surprising coherence of themes-many so extraordinarily close to those of his friend Boccioni as to suggest a sort of intersecting pollination between the two. Russolo was to repeat these early themes, unchanged in their substance, for the rest of his life; being spiritual in character, they corresponded well with futurism's occult side.

To summarize all the instances that show connections between futurism and esoteric preoccupations at various levels-ranging from spirituality to interest in and practice of the occult arts, and also including black and red magic and spiritualism-would be an ambitious undertaking. Here I shall simply create a backdrop against which to project the fruit of research on Russolo's interest in the occult and my reinterpretation of his sound-related activities in the context of this interest.

I am not the first to mention the influence of the occult arts on the futurist movement. Sporadic references to this influence can be found in volumes, catalogs, and essays on futurism and the visual arts edited by Calvesi and Maurizio Fagiolo dell'Arco. Until a few years ago the only contributing monographs available were a brief article by Germano Celant titled "Futurismo esoterico," published in Il Verri in 1970, and Calvesi's very brief article "L'criture mdiumnique comme source de l'automatisme futuriste et surraliste," published in Europe in 1975, in which Calvesi shows connections between mediumistic phenomena and the poetics of the automatic writing adopted first by Marinetti and then by the Surrealists. To these should certainly be added Calvesi's above-mentioned 1967 classic Il futurismo: La fusione della vita nell'arte, in which occult and spiritualist themes, however eccentric, occasionally color the overall discussion.

Renewed interest in the topic began first with the extensive catalog of a 1995 Frankfurt exhibition titled Okkultismus und Avantgarde, which devoted much space to the futurists; this was followed by Flavia Matitti's writing on Balla and theosophy, as well as by the handsome volume by Simona Cigliana (Futurismo esoterico), which takes its title from Celant's essay and is the most complete contribution to the topic to date. In contrast to the earlier sources cited, some of which are limited to a list of facts, Cigliana's book offers a convincing in-depth analysis of the futurists' occult frequentations, albeit primarily limited to the field of literature.

The futurists' interest in the occult can be attributed to their full immersion in the culture of their period, principally inspired by French symbolism, which was in turn a reaction to Comte's mid-nineteenth-century positivism and absolute materialism. In Italy, critiques of positivism and materialism also attacked idealism, and not just in rational and dialectic Hegelian formulations but also in idealism's mainstream Italian dissemination through the writings of the philosopher Benedetto Croce.

It has been maintained that interest in the occult arts and metapsychics can be attributed to the futurists' attraction to the then current understanding of science. There were those who, considering the future of scientific research, maintained that science should include among its fields of inquiry the study of paranormal phenomena and confer legitimacy upon it, since this was the natural direction toward which science was already tending. This view may be true, but it offers only a partial picture of futurism, and it bears the further defect of again putting science and technology at the center of the futurist poetic meditation, as if they were the end of this meditation instead of, as we will see, the means.

Already at this stage, however, it is clear that these occult interests were poles apart from an aesthetic conception preoccupied exclusively with the "simple exaltation of the machine and exterior reproduction of movement." The futurists' interest in science was not always exclusive or absolute, and it was not always blind idolatry. Calvesi addresses this point when he writes, "Boccioni did not want a scientific aesthetics, that is, definable into scientific rules, but only an aesthetics that took the acquisitions of science into account: which is very different."6 For Marinetti the situation was entirely similar: "Art assimilates science intuitively, analogically, by parallelism and also by benefiting from science's technical discoveries, but never by a substitution of methodologies."7 For the futurists, science was above all a means; it was not the end of their aesthetic vision.

The present chapter considers the movement's interest in occultism-alongside its interest in science and technology and its greatly underexplored interest in altered states of consciousness-as a means to achieve out-of-body experiences. Such experiences, in turn, would permit the futurists to observe reality from a hyperreal point of view, as well as to re-create reality through a new, spiritual mode of artistic creation. Subsequent chapters add Russolo's musical activity to those expressions of futurism that are indebted to the occult tradition.

Science and the Occult at the Turn of the Twentieth Century

Interest in the occult would seem to contradict the attention the futurists gave to the latest discoveries of the science and technology of the period. 8 But from the middle of the nineteenth century on, interest in the occult was increasingly shared by scientists and occultists alike, generating such terms as "scientific occultism," which further muddied the waters.9 Increasingly spreading an image of the universe as an organism animated by mysterious and supernatural forces, new scientific discoveries made between the second half of the nineteenth century and the first years of the twentieth showed that idealism, positivism, and materialism gave too restricted a vision of natural phenomena and the cosmos.10

A more dynamic conception of experimental science led various intellectuals of the time to consider occult manifestations as phenomena not yet known because of imperfect human senses and the limitations of human research tools; sooner or later, however, the scientific community was expected to be in a position to measure, understand, and explain. Heisenberg's uncertainty principle would eventually limit, if not altogether undermine, this hope for accurate measurements.

Exhortations to avoid reducing existence (and so the world) exclusively to what human senses can perceive came from all sides, as exemplified by the famous astronomer Camille Flammarion's comment that X-rays were a further proof that "sensation and reality are two very different things."11

Among the many attempts to systematize ways of understanding, ranging from alchemy to metapsychics to spiritualism, and drawn from sources as diverse as the Corpus Hermeticum, medieval mysticism, the neoplatonism of the Renaissance, freemasonry, and Eastern philosophies, was the philosophy of the Rose+Croix, which is worth citing for its direct influence on artistic disciplines.12 But even more relevant was the influence of theosophy.

Blavatsky's theosophy, with its comparativist and encyclopedic popularizing approach, which embraced Eastern philosophical thought as well as having numerous points of contact with scientific research, found fertile ground in the cultural context of the epoch. In fact, it became fashionable in those end-of-the-century artistic circles that still believed in romantic philosophical ideas or had aligned with the new symbolist trend. Theosophy famously called for systematic research of parascientific phenomena that would apply the same criteria used by scientific method to investigate other natural phenomena. Such spiritual research was never intended for utilitarian purposes but only for the spiritual advancement of humanity.

In Italy theosophy paid particular attention to the study of the human psyche. In fact, perhaps because of the charismatic presence of the celebrated Turinese psychiatrist and anthropologist Cesare Lombroso, psychiatry and neurology were in Italy the first disciplines to take an interest in various forms of the occult. Among these forms were parapsychology and parascience (telepathy, clairvoyance, possession, psychokinesis, ideoplastic), as well as correlated mediumistic phenomena.13 The need to push beyond the appearance of things to understand the world and the belief that mediums and artists were gifted with more highly developed spiritual faculties-both principles that betrayed connections with romantic aesthetics-were propositions that futurists maintained on several occasions.

In this "sounding out" of reality the new frontiers of science were certainly helpful. Among the scientific discoveries of the age, that of Rntgen's X-rays in 1895 was one of the most suggestive, because its application implied a complete revolution of the perceptive act itself. Unlike the theories on the fourth dimension or the study of non-Euclidean geometries that affected the representation of the perceptive act, X-rays revolutionized the very act of seeing. This discovery was fundamentally important in the development of theories of the pictorial avant-garde in the first years of the century-and not only for the futurists.14

X-rays bore a metaphoric weight: they encouraged one to view things profoundly rather than occupy oneself with the surface perceptible via the five senses. And an even closer relationship with mediumistic phenomena circulates in the scientific literature of the time: Lombroso, Flammarion, Ochorowicz, and Zoellner all drew a direct connection between Rntgen's research on the vibration of ether waves and the phenomena of ectoplastic condensation.15 It is not surprising, then, to learn that X-rays profoundly fascinated Boccioni, Balla, and Russolo, and that they offered a concrete way of achieving (through the extension of human senses of perception) the futurist interpenetration of planes they promoted in the manifestos of futurist painting.

The futurists' fascination with this new technology is first documented in a passage in the technical manifesto of futurist painting of April 11, 1910: "Who can still believe in the opacity of bodies, while our acuity and multiplied sensitivity makes us intuit the obscure manifestations of mediumistic phenomena? Why must one continue to create without taking account of our visual power that can give results analogous to those of X-rays?"16

The futurists were convinced that X-rays and X-ray-like clairvoyance could help to register otherwise invisible aspects of reality, such as the residual traces of the movement of bodies or the luminous emanations produced by the brain and projected in the surrounding aura-emanations that theosophists called "thought-forms." This protocol of perception based on light and movement permitted one to grasp the spiritual level of reality. The technical manifesto claimed that "by the persistence of the image in the retina, objects in motion multiply, deform, following one another, as vibrations, in the space that they pass through [i.e., of their trajectory] [. . .]. To paint a figure one does not need to make the figure: one needs to render its atmosphere. [. . .] Motion and light destroy the materiality of bodies."17

These convictions would be summarized at the end of the manifesto in the concept of complementarismo congenito (congenital complementarism), a notion that the art historian Marianne Martin, in her Futurist Art and Theory, considered "an occult spiritual experience bringing the artist in closer touch with the universal forces."18 The term complementarismo congenito readily promotes a union of opposites that rings distinctively alchemical, and thus occult.

Space and Time Tamed: Marinetti's Ectoplasm

An examination of the critical texts of Calvesi, Fagiolo dell'Arco, and Celant reveals that all of the most representative futurist artists were to varying degrees concerned with the occult.19 This is certainly true of Marinetti. By celebrating action and movement-a celebration clearly intoxicated with Nietzschianism-his aesthetics celebrated the energy manifested in every vibration of the cosmos, that is, energy itself.

Far from being a proposition of materialistic thrust, Marinetti's obsessive celebration of movement and vibration reflects an occult, symbolist-derived substratum.20 Central to this view is the idea that matter is constituted by condensation of waves vibrating at different intensities; as such, through movement, matter either vanishes or better reveals its implicit spirituality. Basing his ideas on Nietzsche's theory of action, his personal reading of Bergson's vitalism, and Einstein's theory of relativity (which Marinetti probably encountered by way of the popularizing work of Minkowsky), the founder of futurism derived a conception of the world in which, if only because we lack absolute parameters to show stasis, all is perpetual movement.21

According to Marinetti, "absolute space and time do not preexist, nor do any absolutely immovable points nor any objects in absolute movement, because there is no absolute term of reference: object and subject are, always, correlatively but discontinuously mobile."22 According to Calvesi, futurists did not regard "spirit and matter (and therefore [. . .] intuition and intellect)" as separate; they saw them as a unity, under the "same principle of energy."23 As is also true of Boccioni, Marinetti overcame Bergson's dualism of matter versus movement. Matter never exists as absolute inertia: "Matter and movement, rather than contradictory ends, became ends that could be brought back to one single principle."24

Behind this theory of energy we find not only the influence of Nietzsche's interpretations and Einstein's suggestions but also one of the core propositions of alchemy that futurists may have derived from pre-Socratic philosophies: the belief in a universe that may be synthesizable into a single generating principle, a primal matter, existing in various levels of density and from which all things derive.25 This primal matter, a wave vibrating at different frequency, was often referred to as the ether.

The interest in waves and vibrations, and in their relationship to occult themes, is a constant in Marinetti's prose. In his Manifesto della declamazione dinamica e sinottica he writes that the futurist poet/performer will have the task of "metallizing, liquefying, vegetalizing, petrifying, and electrifying the voice, fusing it with the vibrations of matter, themselves expressed by Words-in-Freedom,"26 and in La grande Milano tradizionale e futurista Marinetti recognized in Russolo's enterprise the capacity to "organize spiritually and fantastically our acoustic vibrations."27

A similar transformative approach is found in the manifesto La radia, published with Pino Masnata in 1933. Among other things, the radio set (Marinetti and Masnata have recourse to the feminine gender for the word, radia) is here considered to be:

4. Reception amplification and transformation of vibrations emitted by living beings by living or dead spirits noisy dramas of states of mind without words.

5. Reception amplification and transformation of vibrations emitted by matter Just as today we listen to the song of the woods and of the sea tomorrow we will be seduced by the vibrations of a diamond or of a flower.28

It is, furthermore:

6. Pure organism of radiophonic sensations

7. An art without time or space without yesterday or tomorrow [. . .] The reception and amplification, through thermionic valves, of light and of the voices of the past will destroy time [. . .]

9. Human art, universal and cosmic, that is like a voice with a true psychology-spirituality of the noises, of the voices and of the silence.29

In these passages points of contact with panpsychism are evident. The idea that everything is vibration is an eminently occultist one, as it implies that all phenomena occurring in the world are in some way secretly linked. Once the corpuscular theory of light, inspired by Democritus and upheld by Newton, was put aside in favor of the theory of waves traveling through ether, which lasted until Einstein, it was as if the scientific community implicitly validated the long esoteric tradition that had always included a belief in the correlation between light and sound. The discovery of electromagnetic waves, X-rays, and, shortly after, radioactivity, confirmed this occultist proposition.30 In fact, the theory of waves propagating themselves in the ether reinforced and essentially confirmed an alchemical/synesthetic conception of art, because both sound and light are, according to this vision of physics, waves that only differ in frequency or wavelength-a difference of degree, not of kind.

Futurism was always characterized by a strong synesthetic component, and synesthesia has traditionally been an indicator of the occult (by way of the vibrational tradition).31 This connection was a remnant of the connection between futurism and French symbolism in the latter's most occultist (and psychedelic) moments-one may think of the Baudelaire of Correspondances or the Rimbaud of Voyelles-but also of the Italian version of that same symbolism, alcoholic and brilliant, that we call Milanese scapigliatura, an antibourgeois art movement surely characterized, just as futurism is, by an overlap of scientific and occult interests.32

The debate about synesthesia was widespread at the opening of the twentieth century.33 Marinetti's interest in the relationship between the arti sorelle (sister arts) and the different senses was ever present, even when not taking center stage as it does in his manifesto "Tactilism" (1921, revised in 1924).

Tactilism, Marinetti maintains, could be considered the result of the mortification of the other four senses, producing an empowered sense of touch; this would occur following a deviation of the sun from its proper orbit that would cause its unusual distancing from the earth.34 But, Marinetti maintained, the phenomenon was instead created by "an act of futurist caprice/faith/will." In fact, in an extreme situation such as a planetary catastrophe, the five senses would be reduced to only one. Marinetti wrote, "Everybody can feel that sight, smell, hearing, touch and taste are modifications of a single, highly perceptive sense: the sense of touch, which splits into different ways and organizes into different points."35

In this manifesto, tactilism is a provisional term for a new art form that merges all of the five traditional senses as well as a series of new senses that Marinetti lists. He chooses to give "the name of Tactilism to all the senses that are not specified," since he believes that the perceptive senses are in fact "more or less arbitrary localizations of that confused total of intertwined senses that constitute the typical forces of the human machine"; these forces could in his opinion "be better observed on the epidermal frontiers of our body." Notwithstanding this, the attention here is obviously on the sense of touch; as Marinetti describes it, to arrive at a tactile art, other stimuli (including the visual) must be sacrificed or neutralized.36

Marinetti therefore contemplates a synesthetic emotion-which by definition links different senses by means of association-that is evoked and activated by use of specially made implements that he calls tactile tables (tavole tattili). In tactile art it is exclusively through touch that the perceiver reconstructs, by association, stimuli that, while similar, belong to other expressive fields such as music or painting; this kind of reconstruction is encouraged in the tactile tables. Marinetti chose not to integrate the expressive protocol of the tactile tables with expressive modalities derived from other art forms (like painting or sculpture)-a choice made not to prevent a dialogue between the arts but to protect the newborn art form tactilism and permit it, at least in the beginnings of its journey, to develop autonomously.

Marinetti believed that the sense of touch, when empowered, permits seeing beyond the physical-permits seeing even inside objects, as if by a sort of tactile X-ray vision: "A visual sense is born, at the fingertips. Interscopia is developed, and some individuals are able to see inside their own bodies. Others can shadowy make out the shadowy insides of nearby bodies." The connection with Boccioni's interpenetration of planes, and of its occult and scientific matrices (or implications), could not be clearer.

At its core, Marinetti's tactilism aimed at the perfecting of "spiritual communications between human beings, through the epidermis." Often read as merely an erotic proclamation, this statement was, rather, the testimony of Marinetti's spiritual and occult attitude, perhaps even traceable to the conversations with his father, who was an enthusiastic reader of Eastern philosophy.37 With Tactilism, Marinetti proposed to "penetrate better and outside of scientific methods the true essence of matter" and to promote the type of spiritual experience that could reach the point of "negating the distinction between spirit and matter," an affirmation that in substance overcomes, as stated above, Bergson's dualism of movementversusmatter. Marinetti believed that comprehension of the essence of matter could be obtained by eliminating the mediation of the brain (i.e., of human reason), which is guilty of polluting the virgin, immediate perfection of the tactile experience. As he wrote: "Perhaps there is more thought in the fingertips than in the brain that has the pride of observing the phenomenon [the act of touching]."

According to Marinetti, the new art had more relations with spiritualism and could better demonstrate the validity of theories of reincarnation than other arts: "The futurist Balla declares that by means of Tactilism everyone can enjoy again with freshness and absolute surprise the sensations of his past life, that he could not enjoy again with equal surprise by means of music nor by means of painting."38

Only a few years after this manifesto, the Manifesto della fotografia futurista, a collaboration between Marinetti and Tato published on April 11, 1930, proposed updating Anton Giulio Bragaglia's fotodinamica (photodynamics) by taking advantage of the new technological possibilities. The aesthetic coordinates of this book however are not that distant from Bragaglia's, who was from the beginning of his career interested in phenomena of mediumistic materialization.

The goals of futurist photography in 1930 included, among other things:

4. The spectralizing of some parts of the human or animal body isolated or joined nonlogically; [. . .]

11. The transparent and semitransparent superimposition of concrete persons and objects and of their semiabstract phantasms with simultaneity of memory/dream; [. . .]

14. The composition of absolutely extraterrestrial landscapes, astral or mediumistic by means of thicknesses, elasticity, turbid depths, clear transparencies, algebraic or geometric values, and with nothing human, vegetable, or geologic;39

But in L'uomo moltiplicato e il regno della macchina, part of Guerra sola igiene del mondo of 1915 (and originally in Le futurisme of 1911, perhaps even drafted as early as 1910), Marinetti aspired to a structural modification of man that in future would, thanks to the materialization of wings produced with the force of thought, allow man to fly.40

In L'uomo moltiplicato, Marinetti wrote: "The day it is possible for man to exteriorize his will such that it extends outside of him like an immense invisible arm-on that day Dream and Desire, which today are vain words, will rule sovereign over tamed Space and Time."41 Having lost the reader in this forest of his postsymbolist prose, Marinetti then showed us the way. He believed that this prophecy, which he himself recognized as paradoxical, could be more easily understood by "studying the phenomena of exteriorized will that constantly manifest themselves in sances."

This uomo moltiplicato, a metallic alter egothat would duplicate man without duplicating his defects, would even have the gift of clairvoyance and, in addition to being a "non-human and mechanical type, constructed for an omnipresent velocity, it will be naturally cruel, omniscient and combative." The figure of the multiplied man shows interesting similarities with the metallic animal of the subsequent manifesto, "Ricostruzione futurista dell'universo" by Balla and Depero, the aggressiveness of which would unquestionably have been inebriated with the spirit of World War I interventionism.

For Marinetti, the man of the future was not so much the product of Darwinian evolution as, rather, the transformist hypothesis of Lamarck (whom, indeed he cited in his essay): not an evolution of man but his alchemical transformation into a more perfect being created by the futurists, a "non-human type in whom moral pain, kindness, affection and love, i.e., the only corrosive poisons of inexhaustible vital energy, will be abolished"-in short, a man aiming for a suspended, ataractic, beyond-good-and-evil spiritual state.

These scientific-alchemical themes never disappeared from Marinetti's repertoire. In his 1933 manifesto La radia, he again announced the "overcoming of death" through futurism "with a metallizing of the human body and the appropriating of the vital spirit as machine force."42 In this proclamation, Marinetti reelaborated his 1915 position, according to which the futurists had the power to reawaken mummies with the charismatic electricity of their hand movements. In a passage of "Guerra sola igiene del mondo," Marinetti recounts some of the brawls after the futurist evenings of the first years: "Everywhere, we saw growing in a few hours the courage and the number of men that are truly young, and [we saw] the galvanized mummies that our gesture had extracted from the ancient sarcophagi, becoming bizarrely agitated."43 By now it should be clear that Marinetti's will futuristically to abolish death is a trope, a trope that will recur frequently in Marinetti's writings (e.g., the closing of the manifesto "La matematica futurista immaginativa qualitativa"). 44

Painting the Invisible: Boccioni's Sixth Sense

Contro ogni materialismo.

Umberto Boccioni, "Note per il libro"45

At the intersection of romantic impetuousness and Bergsonian critique of materialism, the personality of Umberto Boccioni stands out dramatically. Departing from a type of formation close to Marinetti's but influenced by Marinetti's theories, Boccioni too demonstrated a strong interest in the occult. Drawn to symbolism, Nietzsche, and Bergson, familiar with the ideas of Einstein, admirer of Wagner, and more generally attracted to the titanic and romantic aesthetic, Boccioni had the vocation and the presumption of the demiurge, the creator of worlds, the materializer.

Boccioni, like Marinetti, overcame the Bergsonian dualism of matter and movement by wedding himself to Einstein's vision (and perhaps to that of Steiner, if one substitutes the term energy for spirit).46 Everything moves, everything vibrates(all bodies are "persistent symbols of the universal vibration," can be read in the technical manifesto of futurist painting), all creation is energy, existing in the form of waves that organize the primal matter, the ether, into different levels of density or, as Boccioni puts it, of intensity. There is no separation between one body and another: in Boccioni's thought, continuity is preferred. In fact, in his article "Fondamento plastico della scultura e pittura futuriste," which appeared in the periodical Lacerba on March 15, 1913, Boccioni writes that "distances between one object and another are not of the empty spaces, but of the continuities of matter of different intensity," immediately adding that in the paintings of the futurists one does not have "the object and the emptiness, but only a greater or lesser intensity and solidity of spaces."47

And he adds, further advocating for continuity,

They accuse us of doing "cinematography, which is an accusation that really makes us laugh, so much it is vulgarly moronic. We do not subdivide visual images: we search for a shape, or, better, a single form [forma unica] that would substitute the new concept of continuity to the old concept of (sub)division.

Every subdivision of motion is completely arbitrary, as it is completely arbitrary every subdivision of matter.48

In confirmation of this proposition, Boccioni presents two quotes form Bergson.

This passage can be better understood after reading the futurist Ardengo Soffici's restatement of this principle of continuity, since he returns the concept to what would have been its original theosophical coordinates. In his article "Raggio," published in Lacerba on July 1, 1914, and republished not by chance a few months later in the Roman theosophical periodical Ultra with the eloquent title "La teosofia nel futurismo," Soffici wrote that bodies are not separated from one another but that "the entire universe therefore is a single whole without interruption of continuity," and that, moreover, "the world is not a molecular aggregate, but a flux of energy with varied rhythms, from granite to thought."49

Soffici goes on to maintain that "a privileged organism, a center of extra-powerful vital force, can in a certain moment and under certain circumstances attract and concentrate within itself its distant parts, the peripheral waves of its energies, making them concrete," and that "an artist can live and make concrete in a work the life of another being, of things, of places that he has not visited. A prophet [can] see and reveal future events-future for sensibilities less acute than his own." In a crescendo of self-centered hubris, Soffici maintains that his consciousness is "a globe of light that shoots its rays all around in accordance with its force," and he concludes, "I am the point of confluence of history and of the world. I am one with eternity and with the infinite."50

Soffici's claim that the psychic energy of the artist could not simply reproduce but must re-create reality was shared by all futurists. I shall investigate how determinative this proposition is in analyzing the work of Russolo. This idea led to the futurists' interest in the creation of ectoplasmic forms by sensitive subjects in a mediumistic trance. In "Fondamento plastico della scultura e pittura futuriste," Boccioni wrote:

When, through the works, one understands the truth of futurist sculpture, one will see the form of atmosphere where before one saw emptiness and then with the impressionists a fog. This fog was already a first step toward atmospheric plasticity, toward our physical transcendentalism which is then another step toward the perception of analogous phenomena until now occult to our obtuse sensitivity, such as the perceptions of the luminous emanations of our body of which I spoke in my first lecture in Rome and which the photographic plate already reproduces.51

A year later, at the close of his volume Pittura, scultura futuriste, Boccioni wrote: "For us the biological mystery of mediumistic materialization is a certainty, a clarity in the intuition of psychic transcendentalism and of plastic states of mind."52 In his preparatory notes for the book, which were published posthumously, Boccioni formulated yet anothereloquent phrase: "Our painting is esoteric."53

In the passage from "Fondamento plastico della scultura e pittura futuriste" quoted above, Maurizio Fagiolo dell'Arco read an allusion to the photographs of ectoplasms produced at the beginning of the century by the notorious Neapolitan medium Eusapia Palladino.54 Both Marinetti and Boccioni were fascinated by Palladino's sances.55 These sances had became still better known after the director of the Corriere della sera tried to discredit them.56

Palladino based her credibility on the fact that she had agreed to repeat her mediumistic sances in the presence of neurologists and psychologists, and she was defended fiercely by the anthropologist Lombroso. Celant records that Lombroso, along with a Turinese group of faithful followers, was in those years investigating the study of phenomena of psychic condensation and materialization. Lombroso's theories would have been fairly widespread in the artistic circles of the time. Kandinsky, for example, was well informed about the studies on spiritualism that Lombroso conducted in Palladino's mediumistic sances,57 and the young Balla in his early years in Turin took Lombroso's classes.58

Materialization phenomena were also the point of departure for the work of Anton Giulio Bragaglia, the author of that "futurist photodynamism" that incited Boccioni's wrath. In two articles from 1913 titled "I fantasmi dei vivi e dei morti" and "La fotografia dell'invisibile," Bragaglia published photos of fake ectoplasms; in doing so he was following a well-established international trend.59 But the year before, influenced by mediumistic photos and those theories of chronophotography of Muybridge or Maray on which Giacomo Balla based his 1912 paintings of the frame-based breakdown of movement (scomposizione del movimento), Bragaglia had already produced the first works of photodynamism.60 In these works he retraced blurs and trajectories of bodies in movement, aiming to reveal that spiritual essence that is lost as a result of the limitations of the human eye: "In motion, things, dematerializing, become idealized," he declared in his Fotodinamismo futurista.61 Calvesi, considering this phrase to be a departure from Bergsonian ideas, linked it to one of the key phrases of the technical manifesto of futurist painting of 1910: "Movement and light destroy the materiality of bodies." Bragaglia's interest in the supernatural did not exhaust itself in this first phase, as testified by his 1932 photograph Alchimia musicale.

But the passage from Lacerba of March 15, 1913, in which Boccioni talked about "perceptions of the luminous emanations of our body," seems actually to refer to the particular metapsychics phenomena that Annie Besant and Charles Webster Leadbeater called "thought-forms." Their book Thought-forms of 1901 was read assiduously in the early twentieth century by artists who were interested in abstract painting. In fact, it exerted great influence over the work of Kandinsky, Kupka, Malevich, and Mondrian.

The book's central proposition is that all thoughts and emotions create corresponding forms and colors in the aura that surrounds the physical body of every human being. These forms and colors are directly determined by the vibrations of the aura, which only clairvoyants can perceive. According to Besant and Leadbeater, the aura of an individual is composed of the union of different "bodies," among which are the astral body, generated by the passions, and the mental body, generated by the thoughts. The vibrations of the astral and mental bodies have the power to produce special psychic forms, both concrete and abstract, which they called thought-forms. Thought-forms can move freely, and they can distance themselves from the body if the energy of the mind that produced them is sufficient. Their color is based on the quality of the thought, their form on its nature, and their sharpness on its clarity.62

Besant's and Leadbeater's book contain a famous series of color plates painted by various artists on indications furnished by the authors after experiencing trances. Their indications were intended to document scientifically, down to the smallest detail, the thought-forms produced by subjects while feeling emotions ranging from devotion to fear and rage that were collected on specific occasions, at specific times of the day. The largely abstract plates attracted the interest of artists of the time, as did the illustrations of Leadbeater's Man Visible and Invisible of 1902. Thought-forms was quickly translated into a number of languages; in Italy it was first disseminated in the 1905 French translation, in which version it was read by Luigi Pirandello and influenced his poetics from the writing of Il fu Mattia Pascal onward.63

It is useful, however, to remember that Boccioni first expressed interest in the occult in that Roman lecture of 1911 that he referred to in his Lacerba article of March 15, 1913, a lecture in which his spirituality is clearly revealed. The text of the lecture, which remained unpublished for a long time, represents one of the high points of Boccioni's poetics. Conscious of its relevance, he referred to it often in his subsequent works. His familiarity with the books of Leadbeater and Besant, particularly Thought-forms, emerges from the very opening lines of the lecture, where, in prophesizing the art of the future, Boccioni affirms:

There will come a time when a painting will no longer be enough. Its immobility will be an archaism when compared with the vertiginous movement of human life. The eye of man will perceive colors like feelings in themselves. Multiplied colors will have no need of forms to be understood, and pictorial works will be whirling musical compositions of enormous colored gases, which on the scene of a free horizon, will move and electrify the complex soul of a crowd that we cannot yet imagine.64

The reference to the use of colors as "feelings in themselves," the use of "colored gases" that can electrify the soul, and the synesthetic link between colors and musical composition are all concepts from Thought-forms. In that same year, 1911, Luigi Russolo exhibited perhaps his most ambitious canvas, on which he had worked for many years.65 Titled La musica, it represents a whirling azure wave that unfolds in the air while the protagonist of the painting, a pianist, executes equally whirling musical figurations on a keyboard. Russolo's painting probably inspired Boccioni's visionary remarks above; and it certainly inspired some elements of Citt che sale, Boccioni's masterpiece of 1910-1911 (fig. 3).B66[fig.3]/B

The synesthetic hypothesis returned in the closing words of Boccioni's 1911 lecture, where Boccioni clarified that by painting the sensation, the futurists stop "the idea before it can be localized in any one sense and be determined either as music, poetry, painting, architecture, that way capturing without any mediation the primal universal sensation."67 Moreover, because futurists live in the absolute, Boccioni maintained that it was necessary for those wishing to understand their works to be not only extremely intelligent but also ready "to enter into contact with pure intuition," which is possible only "after a long and religious preparation."68

Thanks to this spiritual preparation, we are endowed with a new sensitivity that, through new perceptive and psychic means, guides us in the search for the absolute, Boccioni writes:

We painters [. . .] feel that this sensitivity is a psychic divining force that gives the senses the power to perceive that which never until now was perceived.69 We think that if everything tends toward Unity, that which man until today has sought to perceive in unity is still a miserable blind infantile decomposition of things.70

Boccioni believed that the artist must aspire to re-create this unity from the "chaos that envelops things." Sensation is the synthesis, the essence of things, their transfiguration. It is the "subjective impression of Nature."

Moving from the more spiritual aspects of the artistic currents that had gone before (divisionism, impressionism, symbolism), Boccioni arrived at a definition of futurism as the culmination and overcoming of these previous artistic currents. Divisionism represents for Boccioni the achievement of a "symphonic and polychromatic unity of the painting that will become more and more a universal synthesis." With the impressionists, figures and objects, although still in a fairly embryonic way, "are already the nucleus of an atmospheric vibration." But the impressionists exchanged "appearance for reality." It was their limit, and as a result they were trapped in a superficial representation of nature.

Boccioni considered the painting style of the Italian symbolist Gaetano Previati, in which he noted contacts with the "Rosa Croce," which was the direct predecessor of futurist painting. In Previati, "forms begin to speak like music, bodies aspire to make themselves atmosphere, spirit, and the subject is ready to transform itself into a state of mind."

Boccioni perceived futurism as a new kind of impressionism: "Our impressionism is absolutely spiritual since more than the optical and analytical impression, it wishes to give the psychic and synthetic impression of reality." The spiritual role of futurist painting and the psychic force that it develops exhibits far loftier ambitions than French impressionism. In Boccioni's words, it "hypnotizes, grasps, envelops and drags the soul to the infinite." Boccioni had already defined this psychic synthesis as "simultaneity of state of mind."It was a mnemonic-optical representation of what is remembered and what is seen; in substance, it was a spiritualization of the perceptive experience. As if it were an X-ray view, this psychic synthesis offered possibilities of "penetrating the opacity of bodies."

The influence of X-rays and the mythology that the futurists developed around them returns with Boccioni's mention of X-rays in a catalog note for the painting La risata (also painted in the year 1911), which was prepared for the program of the 1912 London exhibition: "The scene is round the table of a restaurant where all are gay. The personages are studied from all sides and both the objects in front and those at the back are to be seen, all those being present in the painter's memory, so that the principle of the Roentgen rays is applied to the picture."71

This quote shows similarities with his affirmations in the Roman lecture. For Boccioni the model of the modern artist was the "clairvoyant painter," capable of "painting not only the visible but that which until now was held to be invisible."72 He believed that the modern painter "can only paint the invisible, clothing it with lights and shadows that emanate from his own soul." Thanks to the progress-spiritual and technological-of the modern age, the five senses can be transcended: "It is our futurist hypersensitivity that guides us and makes us already possess that sixth sense that science strains in vain to catalog and define."73

This perceptive sensitivity permitted the futurist artist to understand the spiritual essence of the movement of bodies. Everything is perennially in motion, all is composed of the same waves that have various grades of density and that vibrate at different intensities. "Bodies are but condensed atmosphere," Boccioni wrote, and minerals, plants, and animals are composed of "identical nature." This new sensitivity is a true and real "psychic divining force" that allows one to grasp that substantial "Unity" of everything that Boccioni considered-as he phrases it in his lecture notes in a crossed-out line-the symbol of the "universal vibration." 74 Futurist painting aspired to reproduce a more profound reality as it is perceived by the subject and as it produced states of mind in the subject: "If bodies provoke states of mind through vibrations of forms, it is those that we will draw."

The following excerpt from the closing paragraph of the Roman lecture is both the most visionary passage of that document and the one where Boccioni's familiarity with Leadbeater is most evident:

There is a space of vibrations between the physical body and the invisible that determines the nature of its action and that will dictate the artistic sensation. In short, if around us spirits wander and are observed and studied; if from our bodies emanate fluids of power, of antipathy, of love; if deaths are foreseen at a distance of hundreds of kilometers; if premonitions give us sudden joy or annihilate us with sadness; if all this impalpable, this invisible, this inaudible becomes more and more the object of investigation and observation: all of this happens because in us some marvelous sense is awakening thanks to the light of our consciousness. Sensation is the material garment of the spirit and now it appears to our clairvoyant eyes. And with this the artist feels himself in everything. By creating he does not look, does not observe, does not measure; he feels and the sensations that envelop him dictates him the lines and colors that will arouse the emotions that caused him to act.

The Craft of Light: Balla's Occult Signature

In Balla one finds again the confluence of two streams common among many of his futurist comrades: the scientific/positivist and the spiritualist.75 The merging of these two tendencies into a sort of metaphysical rationality would constitute, toward the end of the nineteenth century, one of the aims of theosophy. As Linda Henderson maintains, the preferred meeting place between science and spirituality is the theory of vibrations.76 In the light of this convergence of ends, it is no surprise that Balla, literally obsessed with vibrations, was involved with theosophy for many years, and that an understanding of his relations with it are crucial to reconstructing his artistic journey.

During his formative years in Turin, Balla studied with Cesare Lombroso (whose contacts with spiritualism have been mentioned by Germano Celant, among others).77 But the encounter first with freemasonry and occultism, and later with theosophy, occurred only in 1895, once Balla had moved to Rome. In the first years of the century, Balla furthered his interest in psychiatry by reading Hoepli's popular compendia and manuals.78 His interest in X-rays may have been piqued by his acquaintance with Professor Ghilarducci, an expert on radiology, psychology, and electrotherapy, whose portrait Balla painted in 1903.79 This is indicated in an undated entry in his notebooks: "Roentgen rays and their applications."80 I believe he made this entry to remind himself to look into Ignazio Schincaglia's popular 1911 book Radiografia e radioscopia: Storia dei raggi Roentgen e loro applicazioni piu importanti.

The supernatural element is already present in some of Balla's first Roman works, both in the impressive dimensions of Ritratto della madre from 1901 and in the metaphysical angle and hyperrealism of the formidable Fallimento of 1902.81 As early as 1904 he maintained a friendship with Ernesto Nathan, an occultist and freemason (he was grand master of the Grande Oriente d'Italia in 1899 and again in 1917), who in 1907 became the first anticlerical mayor to take office in the Campidoglio. Nathan acquired nine canvases from Balla and commissioned a portrait in 1910, and Balla even taught painting to Nathan's daughter, Annie.82 Notwithstanding his contact with Nathan, Balla apparently never affiliated himself with a lodge.83

Information about Balla's first contact with theosophy comes from Balla's daughter Elica: "In 1916 Balla is also interested in psychic phenomena and attends the meetings of a society of theosophists presided over by General Ballatore; they hold, in said society, sances. [...] Inspired by this interest, [...] he outlines some sketches on this subject and then a larger painting, aptly titled Trasformazione forme spiriti" (fig. 4).B84[fig.4]/B

Flavia Matitti has reconstructed the history of the circle around Generale Ballatore, the "Gruppo Teosofico Roma," and Balla's relationship with that circle. Gruppo Roma was founded in 1897 and recognized as a theosophical association in 1907. In the same year, the first issues of the periodical Ultra came out; in it Ballatore published articles on hyperspace and the fourth dimension; later he wrote on radioactivity. Ultra was the official organ of Gruppo Roma until 1930. In October 1914, Ardengo Soffici published his article "La Teosofia nel futurismo" in Ultra.85

Psoriasis Pictures – Psoriasis Symptoms, Treatment, Cures

Posted: at 10:41 pm

There is no substitute for visiting a doctor or dermatologist for help in getting a diagnosis and receiving treatment advice for psoriasis. However, because there are a large number of treatments which are considered effective, some of which are quite simple and inexpensive, many individuals can also find success in treating their psoriasis on their own. How? By informing themselves about the variety of available treatments and then treating themselves through a careful trial-and-error approach. Though there is still no simple cure for all psoriasis, many can find relief and partial or even total clearing of their skin by exploring available treatment options.

In this section describing the treatment of psoriasis, we will briefly review only some of the more popular and effective treatments, some of which involve using prescription or over-the-counter drugs and others which are more natural. However, before describing these treatments lets briefly review what causes psoriasis.

Psoriasis is commonly understood to be a disorder of the immune system, and is called an auto-immune disorder. In psoriasis ones own immune system, and in particular, ones T-helper cells, mistakenly attacks ones own skin cells. Most psoriasis treatments focus on addressing this immune response, either by suppressing the immune system, by removing the source or a link of the immune response, or by treating the symptoms on the skin. Ok, now lets get on to a brief review of some of the more common treatments.

Biologics- Biologics are a new class of drugs for treating more severe cases of psoriasis, and include Amevive, Enbrel, Humira, Remicade, and now Stelara, among others. Amevive works by blocking the T-cell immune response, and Enbrel, Humira, and Remicade work by blocking another key factor in the immune response, which is called TNF-alpha. Stelara, the most recent to be approved, works by blocking the activation of some of the interleukin chains in the immune response. The biologics have given hope to many with moderate to severe psoriasis who were not previously helped by other treatments, however biologics also have a higher risk of sometimes serious side effects, such as infections. Other drawbacks are that the biologics usually have to be administered by injection or infusion, do not work for everybody, are very expensive, and the symptoms of psoriasis usually return after treatment ends.

Coal Tar- An old and common form of treatment used to control mild cases of psoriasis, coal toar is used in shampoos and creams. Though coal tar can reduce itching and inflammation for some people, it is only moderately effective, is messy, can irritate the skin and in high concentrations can be toxic and possibly carcinogenic.

Coconut Oil- Coconut oil has been receiving more attention recently as a treatment for psoriasis sufferers, both as a dietary supplement and as a skin ointment. Coconut oil contains high levels of lauric acid, which is known to help destroy candida in the intestinal tract, thereby healing one of the possible underlying causes of psoriasis. Coconut oil has also been shown to reduce inflammation, both when taken as a nutritional supplement or when applied to the skin.

Cyclosporin- Cyclosporin is an immunosuppressant and is effective at reducing psoriatic symptoms because it reduces and suppresses the immune system For the same reason, however, cyclosporin comes with a higher risk of side-effects and is usually only prescribed for more severe cases of psoriasis.

Diet Modification- Modifying ones diet can often be the most effective form of controlling psoriasis. Why? There is increasing evidence that byproducts from food may be the triggers for the immune response which causes psoriasis. Some researchers have proposed that leaky gut syndrome (also called intestinal hyperpermeability) may be responsible for the leaking of food-based agents from the intestinal tract into the bloodstream. Thus, diet modification may help by not only removing the food triggers from ones system, but also by helping to heal ones intestinal tract, perhaps by combatting an overgrowth of candida, which is one possible cause of leaky gut syndrome. Those that are serious about controlling their psoriasis and that want to do so with minimal cost and risk of side-effects from medications should explore the research available on controlling psoriasis through modifying ones diet. Some common food triggers include dairy products, highly acidic foods, fermented foods, alcohol, sugars, nuts, wheat, gluten, nightshades, and many others; however, it is important to recognize that different people may have different food triggers- one needs to experiment for oneself. Also, in addition to removing certain items, many have benefitted from adding other items to their diet, such as cocounut oil, fish oil and other omega 3s, folic acid, zinc, antioxidants, Vitamin D and probiotics.

Dithralin (Anthralin) Dithralin is a synthetic form of an extract from the bark of the South American araroba tree. It is often quite effective, and works by blocking cell proliferation. It often takes a while to start working and can stain and irritate the skin. Dovonex and other Vitamin D analogues- Dovonex, the brand name for calcipotriene, is the most well known and widely used form of the Vitamin D analogues which are used to treat psoriasis. Others are Vectical and tacalcitol. Dovonex is a synthetic form of Vitamin D3, and works by inhibiting skin cell growth and proliferation. Many people report good results with Dovonex, and the known side effects are minimal, however, it can take a number of weeks before seeing results and some people report minimal clearing. Recently, the Vitamin D analogues have also sometimes been formulated to include hydrocortisone.

Methotrexate- Like cyclosporin, methotrexate is a systemic medication with more potentially serious side effects, but which can also offer relief for more serious cases of psoriasis as well as severe cases of psoriatic arthritis. Methotrexate works by inhibiting cell growth, and was originally approved for use as a chemotherapeutic treatment for cancer. The most serious potential side-effect of taking methotrexate is liver damage, and its use must be monitored by medical professionals.

Moisturizers- There are many forms of moisturizers used to treat psoriasis, which are helpful because they not only can soothe the skin and reduce itching, but because they can also help remove the top layer of scales, allowing other agents to more easily reach and treat the underlying skin cells. Oatmeal baths, salicyclic acid, epsom salt baths, saltwater bathing, and a variety of oils are just a few of many moisturizing treatments. Some moisturizers, such as coconut oil and ocean or salt water, may also work by reducing inflammation as well as merely lifting scales and soothing skin.

Omega 3s (Fish Oil)- Dietary supplements such as fish oil containing Omega 3 fatty acids have been shown to reduce inflammation and some studies and people report good results.

Phototherapy, Sunlight- There are a number of different forms of phototherapy used to control psoriasis, which work by reducing skin cell growth. Though often effective, with phototherapy symptoms get worse before they get better, and the potential for overexposure brings with it a carcinogenic risk, hence the importance of medical oversight when choosing phototherapy.

Retinoids Topical retinoids such as Tazorac come in creams and gels, and are a synthetic form of Vitamin A. Tazorac is the brand name for Tazoratene, and is also used to treat acne. Skin irritation is one side-effect, and it often takes 2-12 weeks to see results.

Topical Corticosteroids- The most common form of treatment. Topical steroids such as hydrocortisone are used in a variety of forms and applied to the skin. They work by reducing the inflammatory reaction. Topical steroids will usually provide temporary relief and reduce inflammation, scaling and itching, however, they do not address the underlying source of the symptoms, and because of side effects are usually only recommended for temporary use.

Pityriasis rosea – Wikipedia, the free encyclopedia

Posted: at 10:41 pm

Pityriasis rosea (also known as pityriasis rosea Gibert[1]) is a skin rash. It is benign but may inflict substantial discomfort in certain cases.[2] Classically, it begins with a single "herald patch" lesion, followed in 1 or 2 weeks by a generalized body rash lasting up to 12 weeks, however usually around 6 - 8.[3][4][5]

The symptoms of this condition include:

The cause of pityriasis rosea is not certain, but its clinical presentation and immunologic reactions suggest a viral infection as a cause. Some believe it to be a reactivation of herpes viruses 6 and 7, which cause roseola in infants.[9][10][11][12]

Experienced practitioners may make the diagnosis clinically.[5] If the diagnosis is in doubt, tests may be performed to rule out similar conditions such as Lyme disease, ringworm, guttate psoriasis, nummular or discoid eczema, drug eruptions, other viral exanthems.[5][13] A biopsy of the lesions will show extravasated erythrocytes within dermal papillae and dyskeratotic cells within the dermis.[5]

A set of validated diagnostic criteria for pityriasis rosea[14][15] is as follows:

A patient is diagnosed as having pityriasis rosea if:

The essential clinical features are the following:

The optional clinical features are the following:

The exclusional clinical features are the following:

No treatment is usually required.

Oral antihistamines or topical steroids may be used to decrease itching.[5] Steroids do provide relief from itching, and improve the appearance of the rash, but they also cause the new skin that forms (after the rash subsides) to take longer to match the surrounding skin color. While no scarring has been found to be associated with the rash, scratching should be avoided. It's possible that scratching can make itching worse and an itch-scratch cycle may develop with regular scratching (that is, you itch more because you scratch, so you scratch more because you itch, and so on). Irritants such as soaps with fragrances, hot water, wool, and synthetic fabrics should be avoided; a soap containing moisturizers (such as goat's milk) may be used, however, and any generic moisturizer can help to manage over-dryness. Calamine lotion may be soothing to the skin and reduce itching. Emulsifiers should be used instead of soaps, as emulsifiers are gentler on the skin and include cleansers, eliminating the need for soap.

Direct sunlight makes the lesions resolve more quickly.[5] According to this principle, medical treatment with ultraviolet light has been used to hasten resolution,[16] though studies disagree whether it decreases itching[16] or not.[17] UV therapy is most beneficial in the first week of the eruption.[16]

Oral erythromycin was effective in treating patients.[18]

Human Herpes Virus 6 or Human Herpes Virus 7 has been hypothesized to be the cause. The antiviral drug Acyclovir can reduce length of duration and severity.[19]

In most patients, the condition lasts only a matter of weeks; in some cases it can last longer (up to six months). The disease resolves completely without long-term effects. Two percent of patients have recurrence.[20][21]

The overall prevalence of PR in the United States has been estimated to be 0.13% in men and 0.14% in women. It most commonly occurs between the ages of 10 and 35.[5] It is more common in spring.[5]

PR is not viewed as contagious,[2][22] though there have been reports of small epidemics in fraternity houses and military bases, schools and gyms.[5]

A Revolution in the Arts – All-Art.org

Posted: October 13, 2015 at 11:40 am

Early Russian Avant-garde Movements

During the first two decades of the 20th century. Cubism and Futurism were adopted and developed by Russian artists who. except for those living outside Russia, had not previously been involved in the European avant-garde movements. From 1905 until the outbreak of World War I and, subsequently, from the time of the October Revolution until the mid-1920s, three important initiatives were launched in succession: Rayonism, Suprematism, and Constructivism. Founded on intellectual discipline and geometry, these modes entailed original theoretical and pictorial developments, along the lines of Abstractionism. Although aware of its legacy in painting and literature, young Russian artists felt burdened by the cultural tradition of realism and rejected it in favour of the new developments in France. They were mesmerized by the collections of Post-Impressionist works by Cezanne, Matisse, and Picasso, which were brought to Russia by wealthy merchants such as Shchukin and Morozov. who allowed public viewings.

Russian artists also admired Italian Futurism, avidly reading translations of the manifestos and attending Marinetti's lectures, held in Moscow from 1910 onwards. The Golden Fleece exhibitions of 1908 and 1909 included works by Natalia Goncharova and Mikhail Larionov (1882-1964) that recalled national tradition in robust primitivist scenes. In 1912. however, work presented at the so-called "Donkey's Tail" exhibition showed that these two artists had already started to embark upon a modernization of Russian painting. Although independent and critical of Western culture, these painters set great store by the Cubo-Futurists' experiments in the use of colour, dynamism of line, and the liberation of art from naturalistic representation.

In his "Manifesto of Rayonism" (published in April 1912 and revised in 1913 for the Target exhibition in Moscow), Larionov defined his new artistic theories as "a synthesis of Cubism, Futurism, and Orphism". Rayonism is said to have drawn its inspiration and name from the scientific discoveries of radioactivity and ultraviolet rays, which revealed the sum of rays derived from an object and the dynamic and simultaneous transmission of light. The movement was promoted in Western Europe throughout 1913 and 1914, and was taken up zealously in Rome during 1917, but failed to survive the upheavals of war. Its main protagonist, Larionov, moved to France to concentrate on stage designs for the Ballets Russes.

The works shown by Kasimir Malevich (1878-1935) at "0.10. The Last Futurist Exhibition", held in St Petersburg in 1915, represented an important move towards nonrepresentational art. He had sought to "liberate art from the dead-weight of objectivity" in 1913 by painting a single black square on a white ground, the sole content of which was "the sensitivity of nonobjectivity". The aim of this new movement, which Malevich named Suprematism, was to express the absolute supremacy of sensitivity in the creative arts. The goals of his manifesto, produced in collaboration with the poet Maiakovsky, were to liberate painting from the shackles of naturalistic or symbolic references; to divest it of any practical purpose; and to ensure that it existed only as pure aesthetic sensibility. This involved the composition of elementary geometric shapes, usually squares, which were initially painted black, but were later produced in several colours. The quest for purity and immateriality of form reached its logical conclusion in 1918 with a white square on a white ground. Vladimir Tatlin (1885-1953) exhibited at the St Petersburg shows held in 1915 and was a pupil of Larionov. His work evolved from the Neo-Primitive style towards more abstract compositions. His stormy friendship with Malevich ended when theoretical disagreements arose between them in 1917. Malevich continued to reject any connection between the "pure plastic sensibility' of art and the problems of practical life, whereas the Constructivists, led by Tatlin, held that art had to abandon individual aesthetic stances if it was to help emancipate modern society.

_____________

Rayonism [ Rus. Luchizm].

Term derived from the word for ray (Rus. luch), used to refer to an abstract style of painting developed by the Russian artist Mikhail Larionov. Larionov himself claimed that he had painted his first Rayist work in 1909, but modern scholarship has shown his first Rayist works to date from the latter half of 1912. These included Glass: Rayist Method (New York, Guggenheim) and Rayist Sausage and Mackerel (Cologne, Mus. Ludwig). In 1913 Larionov began to expound and elaborate his theory in a series of manifestos.

Rayonism

(Encyclopaedia Britannica)

Russian Luchism (Rayism) Russian art movement founded by Mikhail F. Larionov, representing one of the first steps toward the development of abstract art in Russia. Larionov exhibited one of the first Rayonist works, Glass, in 1912 and wrote the movement's manifesto that same year (though it was not published until 1913). Explaining the new style, which was a synthesis of Cubism, Futurism, and Orphism, Larionov said that it is concerned with spatial forms which areobtained through the crossing of reflected rays from various objects.

The raylike lines appearing in the works of Larionov and Natalya Goncharova bear strong similarities to the lines of force in Futurist paintings. Rayonism apparently ended after 1914, when Larionov and Goncharova departed for Paris.

Russian Avant-garde Movements

After the Bolshevik revolution and World War I, a new-artistic trend emerged in Europe. Unlike Dadaism's nihilistic stance, the aesthetic individualism of Suprematism, or Mondrian's abstract mysticism, which rejected all political and social value for art, this new movement stressed the need for artists to become actively involved in reshaping society. It declared that the combined forces of art, craftsmanship, and industry could help build a better world. In post-Tsarist Russia, the first Commissar of Education, Anatoly Lunacharsky, was broadly sympathetic towards modern artistic movements, and permitted avant-garde artists to play a role in cultural activity and teaching. Considered useful to society, art was expected to concentrate on architecture, the design of manifestos and household objects, and printing. Known as Constructivism, this movement sought to put these revolutionary aims and ideals into practice. It rejected any creativity that did not have a purpose and categorized it as a specific, purely aesthetic activity. From 1915 to 1916, Tatlin (1885-1953) and Rodchenko (1891-1956) made utensils and household objects in iron, glass, and other industrial materials. They were joined by two brothers. Antoine Pevsner (1886-1962) and Naum Gabo (1890-1977). and the Mayakovsky group, organized by LEV (the Left Front) whose manifesto was published in 1923.

After the first flush of shared enthusiasm among the artists, differences soon emerged over methods and results. Following the subsequent schism in the Constructivist group, Pevsner and Gabo espoused the virtues of realism, which, as expounded in their "Realistic Manifesto" of 1920, supported the absolute value of art and its independence from the structure of society, be it capitalist or communist. Immediately, Rodchenko and his wife Varvara Stepanova delivered their riposte in the "Programme of the Productivist Group", airing extreme utilitarian and "functional" views and ending with the exhortation: "Down with art! Up with technology! Down with tradition! Up with Constructivist technical progress!" The art produced by Moscow artists who had emigrated, many of them before World War I, was much more in tune with international movements. Artists such as Larionov, Sonia Delaunay, Goncharova, Chagall, and Soutine settled in Paris, where they found the artistic climate more congenial than in their native country.

_____________ Cubo-Futurism

Alexander Rodchenko Vladimir Mayakovsky, Moscow, 1924

Cubo-Futurism

Term first used in 1913 in a lecture, later published, by the Russian art critic Korney Chukovsky (18821969) in reference to a group of Russian avant-garde poets whose work was seen to relate to French Cubism and Italian Futurism; it was subsequently adopted by painters and is now used by art historians to refer to Russian art works of the period 191215 that combine aspects of both styles. Initially the term was applied to the work of the poets Vladimir Mayakovsky, Aleksey Kruchonykh, Velimir Khlebnikov, Benedikt Livshits (18861939) and Vasily Kamensky (18641961), who were grouped around the painter David Burlyuk. Their raucous poetry recitals, public clowning, painted faces and ridiculous clothes emulated the activities of the Italians and earned them the name of Russian Futurists. In poetic output, however, only Mayakovsky could be compared with the Italians; his poem Along the Echoes of the City, for example, which describes various street noises, is reminiscent of Luigi Russolos manifesto Larte dei rumori (Milan, 1913).

Vladimir Mayakovsky

(Encyclopaedia Britannica)

born July 7 [July 19, New Style], 1893, Bagdadi, Georgia, Russian Empire died April 14, 1930, Moscow, Russia, U.S.S.R.

the leading poet of the Russian Revolution of 1917 and of the early Soviet period.

At the age of 15 Mayakovsky joined the Russian Social-Democratic Workers' Party and was repeatedly jailed for subversive activity. He started to write poetry during solitary confinement in 1909. On his release he attended the MoscowArt School and joined, with David Burlyuk and a few others, the Russian Futurist group and soon became its leading spokesman. In 1912 the group published a manifesto, Poshchochina obshchestvennomu vkusu (A Slap in the Faceof Public Taste), and Mayakovsky's poetry became conspicuously self-assertive and defiant in form and content. His poetic monodrama Vladimir Mayakovsky was performed in St. Petersburg in 1913. Between 1914 and 1916 Mayakovsky completed two majorpoems, Oblako v shtanakh (1915; A Cloud in Trousers) and Fleytapozvonochnik (written 1915, published 1916; The Backbone Flute). Both record a tragedy of unrequited love and express the author's discontent with the world in which he lived. Mayakovsky sought to depoetize poetry, adopting the language of the streets and using daring technical innovations. Above all, his poetry is declamatory, for mass audiences. When the Russian Revolution broke out, Mayakovsky was wholeheartedly for the Bolsheviks. Such poems as Oda revolutsi (1918; Ode to Revolution) and Levy marsh (1919; Left March) became very popular. So too did his Misteriya buff (first performed 1921; Mystery Bouffe), a drama representing a universal flood and the subsequent joyful triumph of the Unclean (the proletarians) over the Clean (the bourgeoisie). As a vigorous spokesman for the Communist Party, Mayakovsky expressed himself in many ways. From 1919 to 1921 he worked in the Russian Telegraph Agency as a painter of posters and cartoons, which he provided with apt rhymes and slogans. He poured out topical poems of propaganda and wrote didactic booklets for children while lecturing and reciting all over Russia. In 1924 he composed a 3,000-line elegy on the death of Vladimir Ilich Lenin. After 1925 he traveled in Europe, the United States, Mexico, and Cuba, recording his impressions in poems and in a booklet of caustic sketches, Moye otkrytiye Ameriki (1926; My Discovery of America). He also found time to write scripts for motion pictures, in some of which he acted. In his last three years he completed two satirical plays: Klop (performed 1929; The Bedbug), lampooning the type of philistine that emerged with the New Economic Policy in the Soviet Union, and Banya (performed in Leningrad on January 30, 1930; The Bathhouse), a satire of bureaucratic stupidity and opportunism under Joseph Stalin. Mayakovsky's poetry was saturated with politics, but no amount of social propaganda could stifle his personal need for love, which burst out again and again because of repeated romantic frustrations. After his early lyrics this need came out particularly strongly in two poems, Lyublyu(1922; I Love) and Pro eto (1923; About This). To makethings worse, during a stay in Paris in 1928, he fell in love with a refugee, Tatyana Yakovleva, whom he wanted to marry but who refused him. At the same time, he had misunderstandings with the dogmatic Russian Association of Proletarian Writers and with Soviet authorities. Nor was the production of his Banya a success. Disappointed in love, increasingly alienated from Soviet reality, and denied a visa to travel abroad, he committed suicide in Moscow.

Mayakovsky was, in his lifetime, the most dynamic figure of the Soviet literary scene, but much of his utilitarian and topical poetry is now out of date. His predominantly lyrical poems and his technical innovations, however, influenced a number of Soviet poets, and outside Russia his impress has been strong, especially in the 1930s, after Stalin declared him the best and most talented poet of our Soviet epoch.

_____________ Constructivism

Founded in 1913 by Vladimir Tatlin, the Russian Constructivist movement developed from Cubism, Italian Futurism, and Suprematism in Russia, Neo Plasticism in Holland, and the Bauhaus School in Germany. The term Constructivism is used to define non-representational relief construction, sculpture, kinetics, and painting. As a response to changes in technology and contemporary life, it advocated a change in the art scene, aiming to create a new order in art and architecture that referenced social and economic problems. Brothers Naum Gabo and Antoine Pevsner also supported the movement, infusing sculptural elements from cubism and futurism with an allusion to architecture, machinery, and technology. The movements first Constructivist manifesto was written in 1921 when the First Working Group of Constructivists was formed in Moscow. The movement later spread to Holland and Germany before gaining international popularity. The style was initially supported by the Soviet Regime, but later was deemed unsuitable for mass propaganda reasons. Following this decree, Gabo and Pevsner went into exile while Tatlin, Popova and El Lissitzky stayed in Russia. The Constructivist movement was also prominent in theatrical scene design, mostly spread by the efforts of Vsevolod Meyerhold.

Constructivism

Avant-garde tendency in 20th-century painting, sculpture, photography, design and architecture, with associated developments in literature, theatre and film. The term was first coined by artists in Russia in early 1921 and achieved wide international currency in the 1920s. Russian Constructivism refers specifically to a group of artists who sought to move beyond the autonomous art object, extending the formal language of abstract art into practical design work. This development was prompted by the Utopian climate following the October Revolution of 1917, which led artists to seek to create a new visual environment, embodying the social needs and values of the new Communist order. The concept of International Constructivism defines a broader current in Western art, most vital from around 1922 until the end of the 1920s, that was centred primarily in Germany. International Constructivists were inspired by the Russian example, both artistically and politically. They continued, however, to work in the traditional artistic media of painting and sculpture, while also experimenting with film and photography and recognizing the potential of the new formal language for utilitarian design. The term Constructivism has frequently been used since the 1920s, in a looser fashion, to evoke a continuing tradition of geometric abstract art that is constructed from autonomous visual elements such as lines and planes, and characterized by such qualities as precision, impersonality, a clear formal order, simplicity and economy of organization and the use of contemporary materials such as plastic and metal.

Constructivism (Encyclopaedia Britannica) Russian artistic and architectural movement that was first influenced by Cubism and Futurism and is generally considered to have been initiated in 1913 with the painting reliefsabstract geometric constructionsof Vladimir Tatlin. The expatriate Russian sculptors Antoine Pevsner and Naum Gabo joined Tatlin and his followers in Moscow, and upon publication of their jointly written Realist Manifesto in 1920 they became the spokesmen of the movement. It is from the manifesto that the name Constructivism was derived; one of the directives that it contained was to construct art. Because of their admiration for machines and technology, functionalism, and modern industrial materials such as plastic, steel, and glass, members of the movement were also called artist-engineers.

Other important figures associated with Constructivism were Alexander Rodchenko and El Lissitzky. Soviet opposition to the Constructivists' aesthetic radicalism resulted in the group's dispersion. Tatlin and Rodchenko remained in the Soviet Union, but Gabo and Pevsner went first to Germany and then to Paris, where they influenced the Abstract-Creation group with Constructivist theory, and laterin the 1930s Gabo spread Constructivism to England and in the 1940s to the United States. Lissitzky's combination of Constructivism and Suprematism influenced the de Stijl artists and architects whom he met in Berlin, as well as the Hungarian Lszl Moholy-Nagy, who was a professor at the Bauhaus. In both Dessau and Chicago, where because of Naziinterference the New Bauhaus was established in 1937, Moholy-Nagy disseminated Constructivist principles.

Antoine Pevsner

(b Oryol, 18 Jan 1886; d Paris, 12 April 1962).

French painter and sculptor of Russian birth. Son of an industrialist and brother of the sculptor NAUM GABO, he grew up in Bryansk. He studied at the School of Art in Kiev (19029), where according to Gabo he first met Alexander Archipenko, and then spent a three-month probationary period at the Academy of Arts in St Petersburg. Among his early paintings, The Giant (1907) shows the influence of the Symbolist painter Mikhail Vrubel, but Pevsner was also impressed by the Russian Byzantine tradition.

Universal Flowering

_____________

Universal Flowering (Mirovoi rastsvet)

Universal Flowering is the name given by Pavel Filonov to his system of analytical art. The system arose from cubo-futurist experiments and works that he undertook from 1913-1915. It is characterized by very dense, minutely facetted, and relatively flat surfaces created by working from the particular to the general, using the smallest of brushes and the sharpest of pencils. The images have both Cubism's multiple vantage points and Futurism's representation of a figure over time. A number of the paintings, while having a given orientation, are painted as though they could be oriented in a variety of ways. Filonov's philosophy was originally formalized in written form in 1915, which was revised and published as The Declaration of Universal Flowering in 1923 when Filonov was a professor at the (then) Petrograd Academy of Arts. Filonov's main theoretical work The Ideology of Analytical Art (Ideologia analiticheskogo iskusstva) was published in 1930.

Neo-primitivism

Russian movement that took its name from Aleksandr Shevchenkos Neo-primitivizm (1913). This book describes a crude style of painting practised by members of the DONKEYS TAIL group. Mikhail Larionov, Natalia Goncharova, Kazimir Malevich and Shevchenko himself all adopted the style, which was based on the conventions of traditional Russian art forms such as the lubok, the icon and peasant arts and crafts. The term Neo-primitivism is now used to describe a general aspiration towards primitivism in the work of the wider Russian avant-garde during the period 191014. It embraces the work of such disparate painters as Chagall, David Burlyuk and Pavel Filonov, and poets such as Velimir Khlebnikov and Aleksey Kruchonykh.

Russian artists associated with Neo-primitivism include: David Burlyuk, Marc Chagall, Pavel Filonov, Natalia Goncharova, Mikhail Larionov, Kasimir Malevich, Aleksandr Shevchenko.

_____________ Synchromism

Style of painting based on the theory that colour provides the basis for both form and content. It was conceived in Paris shortly before World War I by Morgan Russell and Stanton MacDonald-Wright. It was Russells idea that paintings could be created based on sculptural forms interpreted two-dimensionally through a knowledge of colour properties. Synchromist paintings, stressing an emphasis on colour rhythms, were composed of abstract shapes, often concealing the submerged forms of figures, for example Synchromy in Blue (1916; New York, Whitney) by Macdonald-Wright. The two artists first attracted attention at the Neue Kunstsalon in Munich in June 1913. Their second exhibition of Synchromist painting was at the Bernheim-Jeune gallery in Paris from October to November 1913.

_____________ London Group

English exhibiting society founded in November 1913. On its foundation it absorbed many members of the CAMDEN TOWN GROUP and also incorporated the more avant-garde artists influenced by Cubism and Futurism, some of whom afterwards joined the Vorticist movement. Among the founder-members were David Bomberg, Henri Gaudier-Brzeska, Jacob Epstein, Harold Gilman (the groups first president until his death in 1919), Charles Ginner, Spencer Gore, Percy Wyndham Lewis, John Nash, Christopher Nevinson and Edward Wadsworth. The group was organized in opposition to the conservatism of the Royal Academy and the stagnation of the formerly radical New English Art Club. Though, as can be judged from the names of its founders, it had no homogeneous style or aesthetic, it acted as a focal point for the more progressive elements in British art at that time.

spreading life throughout the solar system "I know that humans will colonize the solar system and one day go beyond." Mike Griffin, former NASA Administrator.

A billion years ago there was no life on land. In a phenomenal development, by 400 million years ago land life was well established. We are at the very beginning of a similar, perhaps even more important, development. Today Earth teems with life, but as far as we know, in the vast reaches of space there are only a handful of astronauts, a few plants and animals, and some bacteria and fungi; mostly on the International Space Station. We can change that. In the 1970's Princeton physicist Gerard O'Neill, with the help of NASA Ames Research Center and Stanford University, discovered that we can build gigantic spaceships, big enough to live in. These free-space settlements could be wonderful places to live; about the size of a California beach town and endowed with weightless recreation, fantastic views, freedom, elbow-room in spades, and great wealth. In time, we may see millions of free-space settlements in our solar system alone. Building them, particularly the first one, is a monumental challenge. If this sounds exciting, read on.

Atopic eczema – Treatment – NHS Choices

Posted: at 7:44 am

There is no cure for atopic eczema, but treatments can ease the symptoms. Many children find their symptoms naturally improve as they get older.

The main treatments for atopic eczema are:

Other treatments include topical pimecrolimus or tacrolimus for eczema in sensitive sites not responding to simpler treatment,antihistamines for severe itching, bandages or special body suits to allow the body to heal underneath, or more powerful treatments offered by a dermatologist (skin specialist).

Read on to learn about the different treatments you may be offered. You can also read a summary of the pros and cons of these, allowing you to compare your treatment options.

As well as the treatments mentioned above, there are thingsyou cando yourself to help easeyour symptoms and prevent further problems.

Eczema is often itchy and it can be very tempting to scratch the affected areas of skin. But scratching usually damages the skin, which can itself cause more eczema to occur.

The skin eventually thickens into leathery areas as a result of chronic scratching. Deep scratching also causes bleeding and increases the risk of your skin becoming infected or scarred.

Try to reduce scratching whenever possible. You could try gently rubbing your skin with your fingers instead. If your baby has atopic eczema, anti-scratch mittens may stop them scratching their skin.

Keep your nails short and clean to minimise damage to the skin from unintentional scratching. Keep your skin covered with light clothing to reduce damage from habitual scratching.

Your GP will work with you toestablish what mighttrigger the eczema flare-ups, althoughit may get better or worse for no obvious reason.

Once you knowyour triggers, you can try to avoid them.For example:

Althoughsome people with eczema are allergic to house dust mites, trying to rid your home of them isn't recommendedas it can be difficult and there is no clear evidence that it helps.

Read more about preventing allergies.

Some foods, such as eggs and cows' milk, can trigger eczema symptoms. However, you should not make significant changes to your diet without first speaking to your GP.

It may not be healthy to cut these foods from your diet, especially in young children who need the calcium, calories and protein from these foods.

If your GP suspects you have afood allergy, you may be referred to a dietitian (a specialist in diet and nutrition), who can help work out a way to avoid the food you're allergic to while ensuring you still get all the nutrition you need.

Alternatively, you may be referred to a hospital specialist such as an immunologist, dermatologist or paediatrician.

If you are breastfeeding a baby with atopic eczema, get medical advice before making any changes to your regular diet.

Emollients are moisturising treatments applied directly to the skin to reduce water loss and cover it with a protective film. They are often used to help manage dry or scaly skin conditions such as atopic eczema.

In addition to making the skin feel less dry, they may also have a mild anti-inflammatory role, and can help reduce the number of flare-ups you have.

Several different emollients are available. You may need to try a few to find one that works for you. You may also be advised to use a mix of emollients, such as:

The difference between lotions, creams and ointments is the amount of oil they contain. Ointments contain the most oil so they can be quite greasy, but are the most effective at keeping moisture in the skin.

Lotions contain the least amount of oil so are not greasy, but can be less effective. Creams are somewhere in between.

If you have been using a particular emollient for some time, it may eventually become less effective or may start to irritate your skin.

If this is the case, your GP will be able to prescribe another product that suits you better. The best emollient is the one you feel happy using every day.

Use your emollient all the time, even if you are not experiencing symptoms. Many people find it helpful to keep separate supplies of emollients at work or school, or a tub in the bathroom and one in a living area.

To apply the emollient:

You should use an emollient at least twice a day if you can, or more often if you have very dry skin.

During a flare-up, apply generous amounts of emollient more frequently, but remember to treat inflamed skin with a topical corticosteroidas emollients usedon their ownare not enough to control it.

Don't put your fingers into an emollient pot use a spoon or pump dispenser instead, as this reduces the risk of infection. And never share your emollient with other people.

If your skin is sore and inflamed, your GP may prescribe a topical corticosteroid (applied directly to your skin), which can reduce the inflammation within a few days.

Topical corticosteroids can be prescribed in different strengths, depending on the severity of your atopic eczema and the areas of skin affected.

They can be very mild (such as hydrocortisone), moderate (such as clobetasone butyrate), or even stronger (such as mometasone).

If you need to use corticosteroids frequently, see your GP regularly so they can check the treatment is working effectively and you are using the right amount.

Don't be afraid to apply the treatment to affected areas to control your eczema. Unless instructed otherwise by your doctor, follow the directions on the patient information leaflet that comes with your medication. This will give details of how much to apply.

Most people will only have to apply it once a day as there is no evidence there is any benefit to applying it more often.

When using a topical corticosteroid:

Occasionally, your doctor may suggest using a topical corticosteroid less frequently, but over a longer period of time. This is designedto help prevent flare-ups.

This is sometimes called "weekend treatment", where a person who has already gained control of their eczema uses the topical corticosteroid every weekend on the trouble sites to prevent them becoming active again.

Topical corticosteroids may cause a mild stinging sensation for less than a minute as you apply them.

In rare cases, they may also cause:

Most of these side effects will improve once treatment stops.

Generally, using a strong topical corticosteroid for many months,using them in sensitive areas such as theface, armpits or groin, or using a large amount will increase your risk of side effects. For this reason, you should be prescribed the weakest effective treatment to control your symptoms.

Antihistamines are a type of medicine that blocks the effects of a substance in the blood called histamine. Theycan help relieve the itching associated with atopic eczema.

They can eitherbe sedating, which cause drowsiness,ornon-sedating. If you have severe itching, your GP may suggest tryinga non-sedating antihistamine.

If itching during a flare-up affects your sleep, your GP may suggest taking a sedatingantihistamine. Sedatingantihistamines can cause drowsiness into the following day, so it may be helpful to let your child's school know they may not be as alert as normal.

In some cases, your GP may prescribe special medicated bandages, clothing or wet wraps to wear over areas of skin affected by eczema.

These can either be used over emollients or with topical corticosteroids to prevent scratching, allow the skin underneath to heal, and stop the skin drying out.

Corticosteroid tabletsare rarely used to treat atopic eczema nowadays, but may occasionally be prescribed for short periods of five to seven days to help bring particularly severe flare-ups under control.

Longer courses of treatment are generally avoided because of the risk of potentially serious side effects.

If your GP thinks your condition may be severe enough to benefit from repeated or prolonged treatment with corticosteroid tablets, they will probably refer you to a specialist.

In some cases, your GP may refer you to a specialist in treating skin conditions (dermatologist).

You may be referred if your GP is not sure what type of eczema you have, normal treatment is not controlling your eczema, your eczema is affecting your daily life, or it's not clear what is causing it.

A dermatologist may be able to offer the following:

A dermatologist may also offer additional support to help you use your treatments correctly, such as demonstrations from nurse specialists, and they may be able to refer you for psychological support if you feel youneed it.

Some people may find complementary therapies such as herbal remedies helpful in treating their eczema, but there is little evidence to show these remedies are effective.

If you are thinking about using a complementary therapy, speak to your GP first to ensure the therapy is safe for you to use. Make sure you continue to use other treatments your GP has prescribed.
