Facebook and Google stocks have diverged, and the reason is Apple – CNBC

While Facebook is in the midst of its biggest stock drop ever and is trading at an 18-month low, Google remains near a record and has easily outperformed all of its Big Tech peers over the past year.

The difference is Apple.

Google and Facebook are the two dominant online ad companies in the U.S. and have been for years. While the companies do very different things and have faced their own unique issues, the five-year stock charts look pretty similar.

Until you hit late 2021.

Facebook vs. Google since beginning of 2017

That's when Facebook founder Mark Zuckerberg's longtime struggle to control his own destiny started hitting his company's financials.

Facebook's apps rely almost entirely on Apple and Google for distribution. So when Apple changed its privacy policy last year, limiting the ability of app developers to target users, Facebook was suddenly stripped of one of its most important assets.

Google also relies on ad targeting to connect marketers with users on many of its properties, but search advertising is a unique asset users tend to "self-target" as they're typing in a search query that explains exactly what they're interested in at that moment.

When it comes to targeting, Google has Android, the world's most popular operating system, giving it control over its own policies. And while Google still needs iOS distribution, it has a cozier relationship with Apple. Google pays Apple billions of dollars a year to be the default search engine on Apple's Safari browser.

Add it all up, and Facebook just told Wall Street that Apple's new App Tracking Transparency (ATT) feature is expected to cost the social media company $10 billion in revenue this year. That's a big reason why Facebook fell well short of its revenue forecast for the first quarter and why the stock plummeted 25% on Thursday, its biggest ever drop, to the its lowest since August 2020.

Google, meanwhile, reported blowout fourth-quarter results earlier this week on the back of a 33% jump in ad revenue, compared to 20% for Facebook. Analysts expect Google parent Alphabet to hit growth of 23% in the first quarter, while Facebook is projecting expansion of just 3% to 11%.

Dave Wehner, the CFO of Facebook parent Meta, said on Wednesday's conference call with analysts that, when it comes to Apple treating search more favorably than other apps because of the Google deal, "the incentive clearly is for this policy discrepancy to continue."

Analysts see the correlation. Advertisers that can no longer get the level of targeting they want on Facebook are spending more on Google.

"Did Apple iOS changes trigger a market share shift from Facebook to Google?" MKM Partners' Rohit Kulkarni wrote in a report on Thursday. "Yes, we believe so." MKM has a buy rating on both tocks.

Sheryl Sandberg, Facebook's operating chief and a former senior executive at Google, said Apple's changes are most harmful to small and medium-sized businesses, which are most reliant on personalization and targeting in their advertising.

"So we're definitely seeing that this has more of an impact forSMBs," she said.

Zuckerberg has been worried about this possibility for a long time. Without owning the device or operating system, Facebook can't fully chart its own path, and is always subject to the whims of other companies. About a decade ago, Facebook designed its own phone, but it was a disaster.

Here's what Facebook said in the risk factors of its IPO prospectus in 2012, which was still the early days of mobile for the company.

"We are dependent on the interoperability of Facebook with popular mobile operating systems that we do not control, such as Android and iOS, and any changes in such systems that degrade our products' functionality or give preferential treatment to competitive products could adversely affect Facebook usage on mobile devices."

Facebook CEO Mark Zuckerberg is seen fencing in the "Metaverse" with an Olympic gold medal fencer during a live-streamed virtual and augmented reality conference to announce the rebrand of Facebook as Meta, in this screen grab taken from a video released October 28, 2021.

In 2014, Facebook acquired a nascent virtual reality headset company called Oculus for $2 billion, giving the company a shot at making the next generation of hardware and integrating its own software.

That acquisition is the foundation for the future that Zuckerberg so much desires. Late last year, he changed Facebook's name to Meta Platforms. In Thursday's earnings report, the company said its Reality Labs group, home to the virtual reality development, lost more than $10 billion in 2021.

Investors are rightly worried. Facebook's core business is losing users, and Apple is flexing in a way that's causing panic.

For Zuckerberg, the answer to his real world problems may be the virtual world. As much as anything, he wants to break free of Apple and Google, so his company gets to be the one making the rules.

Gmails new integrated layout will take over inboxes soon – The Verge

Posted: at 3:41 pm

Google has announced that Gmails new layout, which changes how Google Chat, Meet, and Spaces are integrated, will be available to try starting in February; become default by April; and become the only option by the end of Q2 2022. The view makes it so Googles other messaging tools, which are part of (but not necessarily limited to) its business-focused Workspace suite, are no longer just little windows floating alongside your emails, but get their own screens in Gmail that are accessible with large buttons on the left-hand side.

Google calls this the integrated view, and itll soon be familiar if you (or your employer) are a Workspace customer, or if you use Chat and Meet personally. Starting February 8th, Google says youll be able to start testing the layout for yourself. By April, anyone who hasnt opted in (Google shows that therell be a prompt at some point, encouraging you to do so), will be switched over to the new layout, but will be able to switch back in settings. That option will go away by the end of the second quarter, according to Google, when the new layout becomes the standard experience for Gmail.

The new view could be polarizing while managing chats and meetings can be a bit confusing in the current Gmail layout, it all happens on one screen, which is pleasing if you love data density. But for those looking to focus on one thing at a time, the new interface looks like itll give you easy access to other tools without having them always on the screen. There will, however, be ways to access your Chats from the email screen a Google support page describing the new layout mentions that new notifications will show up as a bubble in the left corner of the screen, and that youll be able to create a mini pop-up window within the interface that you can use to reply.

The company says that there will also be notification bubbles to let you know if other tools need your attention, which could be less distracting than, say, having a list of all your Chats living to the left or right of your emails.

Google has shown that it wants to deeply integrate all its work-related products together, and this layout gives us a taste of what that could look like, with tools like Spaces letting you jump into a spreadsheet without leaving Gmail. While it does seem like youre mostly already able to, as Google puts it when describing the new view, easily switch between your inbox, important conversations, and join meetings without having to switch between tabs or open a new window, its probably fair to argue that it all feels a little tacked-on. Googles screenshots of the new layout do make it seem like the new interface will be more put-together.

The services will also be more integrated Gmails search, for instance, will also turn up Chat messages in the coming months, according to the company (similar to how Hangouts messages also used to be searchable from within Gmail).

Google says that this new layout will be coming to anyone who uses Google Chat. According to Google spokesperson Amanda Lam, the focus of the new integrated view is for users who use multiple apps. By the end of the year, this means users would get this experience if they opt-in to Google Chat or Google Meet.

Update February 3rd, 2:55PM ET: Updated with information that Google has now decided that the layout will be available to anyone who uses Chat and Meet, instead of limiting it to a specific type of customer as was originally announced.

Today I learned a handy trick to zoom in and out of Google Maps – The Verge

Posted: at 3:41 pm

Did you know that Google Maps has a nifty little trick that lets you adjust zoom with just one finger? Because I sure as hell didnt until yesterday, when a tweet from Sketchfab CEO Alban Denoyel alerted me to its existence via a years-old YouTube video from 2013. The shortcut is simple: just double-tap the maps interface, but instead of lifting your finger after the second tap (the shortcut for zooming in), you leave it touching the screen. Then a swipe up zooms out, and a swipe down zooms in. Neat right?

With this knowledge you can say goodbye to awkwardly holding the phone and trying to use two fingers to reposition the map to check your directions when your other hand is busy holding a dog leash, coffee cup, shopping bag, or whatever. Personally Im looking forward to using it the next time Im on a bike and need to whip out my phone to quickly check directions. No more taking both hands off the handlebars for this guy. No sir.

I havent done an exhaustive search, but it looks like this feature is pretty commonplace across mapping apps. It works on Google Maps on both Android and iOS, and also works in other iOS mapping apps like Apple Maps and CityMapper. Have fun!

Two members of Google’s Ethical AI group leave to join Timnit Gebru’s nonprofit – The Verge

Posted: at 3:41 pm

Two members of Googles Ethical AI group have announced their departures from the company, according to a report from Bloomberg. Senior researcher Alex Hanna, and software engineer Dylan Baker, will join Timnit Gebrus nonprofit research institute, Distributed AI Research (DAIR).

In a post announcing her resignation on Medium, Hanna criticizes the toxic work environment at Google, and draws attention to a lack of representation of Black women at the company.

Prior to Timnits hiring, Google Research management had never recruited a Black woman as a research scientist, Hanna states. In one town hall around Googlegeist (Googles annual workplace climate survey), a high-level executive remarked that there had been such low numbers of Black women in the Google Research organization that they couldnt even present a point estimate of these employees dissatisfaction with the organization, lest management risk deanonymizing the results.

Gebru, the former co-lead of Googles AI Ethical research group, was fired by the company in 2020 after co-authoring a research paper that called attention to the potential risks of large-scale language models, a concept similar to the one Google Search employs. The search giant fired another AI ethics researcher, Margaret Mitchell, for her involvement in Gebrus paper shortly thereafter.

While the companys diversity report from last year showed an overall increase in the number of Black employees it hired, there was still an increase in the number of women of color that left the company at the time of the reports release, Black women made up 1.8 percent of Googles workforce. And in December, Californias Department of Fair Employment and Housing (DFEH) launched an investigation over Googles treatment of Black female workers.

We appreciate Alex and Dylans contributions our research on responsible AI is incredibly important, and were continuing to expand our work in this area in keeping with our AI Principles, Google spokesperson Brian Gabriel said in a statement emailed to The Verge. Were also committed to building a company where people of different views, backgrounds and experiences can do their best work and show up for one another.

Google Maps review moderation detailed as Yelp reports thousands of violations – The Verge

Posted: at 3:41 pm

Google explains how it keeps user-created reviews on Google Maps free of fraud and abuse in a new blog post and accompanying video. Like many platforms dealing with moderation at scale, Google says it uses a mix of automated machine learning systems as well as human operators.

The details come amidst growing scrutiny of user reviews on sites like Google Maps and Yelp, where businesses have been hit with bad reviews for implementing COVID-related health and safety measures (including mask and vaccine requirements) often beyond their control. Other reviews have criticized businesses for supposedly leading them to contract COVID-19 or for not keeping to usual business hours during a global pandemic.

Earlier today, Yelp reported that it removed over 15,500 reviews between April and December last year for violating its COVID-19 content guidelines, a 161 percent increase over the same period in 2020. In total, Yelp says it removed over 70,200 reviews across nearly 1,300 pages in 2021, with many resulting from so-called review bombing incidents where coordinated reviews are submitted from users who havent actually patronized a business.

Google explains that every review posted on Google Maps is checked by its machine learning system, which has been trained on the companys content policies to weed out abusive or misleading reviews. This system is trained to check both the contents of individual reviews, but itll also look for wider patterns like sudden spikes in one- or five-star reviews both from the account itself, as well as other reviews on the business.

Google says that human moderation comes into play for content thats been flagged by end users and businesses themselves. Offending reviews can be removed, and in more severe cases, user accounts can be suspended and litigation pursued. Weve found that we need both the nuanced understanding that humans offer and the scale that machines provide to help us moderate contributed content, Googles product lead for user-generated content, Ian Leader, writes.

Its an interesting look at the steps Google takes to keep Maps reviews usable. You can read more in the full blog post.

TechScape: Google is changing how it tracks us online but who benefits? – The Guardian

Posted: at 3:41 pm

Cookies are one of the many questionable pacts we have made online, where privacy is exchanged for convenience without being entirely sure about the consequences. As with so many arrangements involving our data, this deal is being rewritten under the gaze of regulators.

Last week Google issued an update on how it is replacing cookies on its Chrome browser, which is important because two-thirds of web browsing around the world is on Chrome.

Sign up for our weekly technology newsletter, TechScape.

Put simply, a cookie is a text file that is dropped into your browser by a website when you visit it. In the UK and EU, you are asked to consent to multiple cookies when you click on a site (and yes its worth checking just how many cookies you agree to take on when you give your consent).

The new head of the UKs data watchdog, John Edwards, told BBC Radio 4s Today programme last week on international data privacy day that he is no fan of the consent-clicking process. Thats not a very effective way of rebalancing the power relationship between consumers and companies that profit from consumers data, he said.

Cookie monsters

Cookies identify individual users so the website can record all kinds of things about your activity. Some of this info is helpful, like whether you have logged in to the site before, so you dont have to constantly enter your user name and password every time you visit in the future. This sort of thing is known as a first party cookie.

However, there are types of this technology known as third party cookies that facilitate the storing of information (like your browsing history and your location) by commercial partners often marketing or advertising businesses that might make you slightly more uncomfortable. If you check the cookie consent box on any website, you will be surprised at the number of advertising and marketing-related cookies. Third party cookies, through agreements with multiple publishers and websites, are able to create a profile of individual users and serve targeted adverts to you while you browse across multiple websites. Like other news publishers, the Guardian asks readers if it can use cookies, for purposes such as measuring how often readers visit and use our site, and showing readers personalised ads.

In what appears to be a win for privacy advocates and a blow to publishers, advertisers and the intermediaries that facilitate personalised ads across the web, third party cookies are being phased out across the board. This is in part due to pressure from regulators and pro-privacy laws like GDPR. Apple and Mozilla have blocked third party cookies on their Safari and Firefox browsers and Google is doing the same on Chrome by 2023.

Leaving the FLoC behind

Google is replacing third party cookies with a set of technologies called a privacy sandbox and last week it announced it was changing one of the key proposals. The initial plan was to bundle people into groups (cohorts) with similar interests based on their browsing habits and allow advertisers to serve ads to those groups. This was called FLoC, for Federated Learning of Cohorts.

After feedback from the industry, which included warnings that individuals could still be identified as they browsed across the web under the FLoC system, Google is now proposing a different system. It is called Topics, in which the Chrome browser notes your top interests for that week based on your browsing history and registers them in the browser (like a cookie would) under broad categories like fitness or travel, which are limited in number. Advertisers and publishers are able to access this data via a browser API, which is a feed of information that they can tap into.

Then when users visit a site that has signed up to the system, three of the users topics of interest are shared with the site and its advertisers, allowing the site to serve ads that reflect the users interest in, for instance, rock music or cars.

Google said the topics will not include sensitive categories such as gender or race and the system will allow users to see the topics, remove any they dont like or disable the feature completely. The topics are deleted every three weeks.

In the UK the Competition and Markets Authority and the Information Commissioners Office are looking at the proposals, from a competition and privacy perspective (ie are there disadvantages for Googles rivals in provision of online adverts and will users data be abused). Rivals are also concerned that Google, which has said other parts of its business like YouTube will adhere to these changes, still has a basic advantage through the sheer amount of existing data it has on users. Vinay Goel, the Google product director in charge of the sandbox project, says: We have developed these new proposals in the open, seeking feedback at every step to ensure that they work for everyone, without preferential treatment or advantage to Googles advertising products or to Googles own sites.

According to the Open Rights Group, which campaigns for peoples digital rights, Googles new proposals signal an end to the data gold rush under third party cookies. Conducting behavioural profiling in the browser could constitute an alternative to the existing data-free-for-all model, where your browsing activities are broadcasted to thousands of unknown intermediaries, says Mariano delli Santi, legal and policy officer at ORG.

However, the ORG remains concerned over several issues including the lack of a default opt-in stance, which would see a browser omitted from the scheme unless they chose to be included. This is still behavioural profiling, says the ORG.

Goel adds: We started the Privacy Sandbox initiative to improve web privacy for users, and Topics will allow for users to have greater control over relevant ads without sharing sensitive details such as gender or race.

Nobodys happy so everybody wins

It is a big change for the digital advertising industry. Farhad Divecha, managing director of UK digital marketing agency Accuracast, wonders if the shift will satisfy anyone. Privacy advocates are going to feel that this is still not quite enough, because theres reasons why this is still tracking behaviour. And on the flip side, advertisers are going to say youre taking away stuff from me. And youre taking away my ability to target specifically whom I want to be reaching.

Paul Banister, chief strategy officer at US digital ad management firm Cafe Media, says the momentum nonetheless is with privacy. I think the pendulum has swung pretty far towards privacy here. But he adds: because its easier to understand the topics system, hopefully it will be more something that users feel good about. And if users are happier with the outcome that is better for advertisers, because it makes people more supportive of what their data is being used for.

This could be just the beginning as internet users become more aware of that trade off between privacy and convenience, and regulators continue to challenge the marketing industry upon which much of big tech profits rely, the pendulum could swing further.

Jian-Wei Pan: The next quantum breakthrough will happen in five years – EL PAS in English

Posted: at 3:41 pm

Any leap in quantum computing multiplies the potential of a technology capable of performing calculations and simulations that are beyond the scope of current computers while facilitating the study of phenomena that have been only theoretical to date.

Last year, a group of researchers put forward the idea in the journal Nature that an alternative to quantum theory based on real numbers can be experimentally falsified. The original proposal was a challenge that has been taken up by the leading scientist in the field, Jian-Wei Pan, with the participation of physicist Adn Cabello, from the University of Seville. Their combined research has demonstrated the indispensable role of complex numbers [square root of minus one, for example] in standard quantum mechanics. The results allow progress to be made in the development of computers that use this technology and, according to Cabello, to test quantum physics in regions that have previously been inaccessible.

Jian-Wei Pan, 51, a 1987 graduate of the Science and Technology University of China (USTC) and a PhD graduate of Vienna University, leads one of the largest and most successful quantum research teams in the world, and has been described by physics Nobel laureate Frank Wilczek as a force of nature. Jian-Wei Pans thesis supervisor at the University of Vienna, physicist Anton Zeilinger, added: I cannot imagine the emergence of quantum technology without Jian-Wei Pan.

Pans leadership in the research has been fundamental. The experiment can be seen as a game between two players: real-valued quantum mechanics versus complex-valued quantum mechanics, he explains. The game is played on a quantum computer platform with four superconducting circuits. By sending in random measurement bases and measuring the outcome, the game score is obtained which is a mathematical combination of the measurement bases and outcome. The rule of the game is that the real-valued quantum mechanics is ruled out if the game score exceeds 7.66, which is the case in our work.

Covered by the scientific journal Physical Review Letters, the experiment was developed by a team from USTC and the University of Seville to answer a fundamental question: Are complex numbers really necessary for the quantum mechanical description of nature? The results exclude an alternative to standard quantum physics that uses only real numbers.

According to Jian-Wei Pan: Physicists use mathematics to describe nature. In classical physics, a real number appears complete to describe the physical reality in all classical phenomenon, whereas a complex number is only sometimes employed as a convenient mathematical tool. However, whether the complex number is necessary to represent the theory of quantum mechanics is still an open question. Our results disprove the real-number description of nature and establish the indispensable role of a complex number in quantum mechanics.

Its not only of interest regarding excluding a specific alternative, Cabello adds, the importance of the experiment is that it shows how a system of superconducting qubits [those used in quantum computers] allows us to test predictions of quantum physics that are impossible to test with the experiments we have been carrying out until now. This opens up a very interesting range of possibilities, because there are dozens of fascinating predictions that we have never been able to test, since they require firm control over several qubits. Now we will be able to test them.

According to Chao-Yang Lu, of USTC and co-author of the experiment: The most promising near-term application of quantum computers is the testing of quantum mechanics itself and the study of many-body systems.

Thus, the discovery provides not only a way forward in the development of quantum computers, but also a new way of approaching nature to understand the behavior and interactions of particles at the atomic and subatomic level.

But, like any breakthrough, the opening of a new way forward generates uncertainties. However, Jian-Wei Pan prefers to focus on the positive: Building a practically useful fault-tolerant quantum computer is one of the great challenges for human beings, he says. I am more concerned about how and when we will build one. The most formidable challenge for building a large-scale universal quantum computer is the presence of noise and imperfections. We need to use quantum error correction and fault-tolerant operations to overcome the noise and scale up the system. A logical qubit with higher fidelity than a physical qubit will be the next breakthrough in quantum computing and will occur in about five years. In homes, quantum computers would, if realized, be available first through cloud services.

According to Cabello, when quantum computers are sufficiently large and have thousands or millions of qubits, they will make it possible to understand complex chemical reactions that will help to design new drugs and better batteries; perform simulations that lead to the development of new materials and calculations that make it possible to optimize artificial intelligence and machine learning algorithms used in logistics, cybersecurity and finance, or to decipher the codes on which the security of current communications is based.

Quantum computers, he adds, use the properties of quantum physics to perform calculations. Unlike the computers we use, in which the basic unit of information is the bit [which can take two values], in a quantum computer, the basic unit is the quantum bit, or qubit, which has an infinite number of states.

Cabello goes on to say that the quantum computers built by companies such as Google, IBM or Rigetti take advantage of the fact that objects the size of a micron and produced using standard semiconductor-manufacturing techniques can behave like qubits.

The goal of having computers with millions of qubits is still a long way off, since most current quantum computers, according to Cabello, only have a few qubits and not all of them are good enough. However, the results of the Chinese and Spanish teams research make it possible to expand the uses of existing computers and to understand physical phenomena that have puzzled scientists for years.

For example, Google Quantum AI has published the observation of a time crystal through the Sycamore quantum processor for the first time in the Nature journal. A quantum time crystal is similar to a grain of salt composed of sodium and chlorine atoms. However, while the layers of atoms in that grain of salt form a physical structure based on repeating patterns in space, in the time crystal the structure is configured from an oscillating pattern. The Google processor has been able to observe these oscillatory wave patterns of stable time crystals.

This finding, according to Pedram Roushan and Kostyantyn Kechedzhi, shows how quantum processors can be used to study new physical phenomena. Moving from theory to actual observation is a critical leap and is the basis of any scientific discovery. Research like this opens the door to many more experiments, not only in physics, but hopefully inspires future quantum applications in many other fields.

In Spain, a consortium of seven companies Amatech, BBVA bank, DAS Photonics, GMV, Multiverse computing, Qilimanjaro Quantum Tech and Repsol and five research centers Barcelona Supercomputing Center (BSC), Spanish National Research Council (CSIC), Donostia International Physics Center (DIPC), The Institute of Photonic Sciences (ICFO), Tecnalia and the Polytechnic University of Valencia (UPV) have launched a new project called CUCO to apply quantum computing to Spanish strategic industries: energy, finance, space, defense and logistics.

Subsidized by the Center for the Development of Industrial Technology (CDTI) and with the support of the Ministry of Science and Innovation, the CUCO project, is the first major quantum computing initiative in Spain in the business field and aims to advance the scientific and technological knowledge of quantum computing algorithms through public-private collaboration between companies, research centers and universities. The goal is for this technology to be implemented in the medium-term future.

County mass transit system on Google Maps: Why Allegany Access is excited – Hornell Evening Tribune

Posted: at 3:41 pm

It took more than a year of painstaking, detailed work for Access Allegany the public transportation system in Allegany County to go live onGoogle Maps.

When the project finally reached its goal on Jan. 6, Access Allegany mobility manager Gwen Cooper said she was thrilled to pieces to see it come to life and to see how well it works.

With Google Maps, Access Allegany riders have easy-to-understand trip information, including trip times, bus numbers, pick-up and stop locations and transfers, Cooper said.

It was a project involving Ardent Solutions, mobility managers for Allegany Countys mass transit system; 511NY, the free telephone and web transit service which created the General Transit Feed Specification files for the system and Google Transit, which plugged those data files into Google Maps.

Cooper explained why she believes this is such an important step forward for Access Allegany.

Transportation is always in the top three of issues for our community members and we are always looking to increase ridership, she said.

Key to that effort, according to Cooper, is making the service easier to use.

I dont know if youve ever tried to read a bus schedule, but it can be extremely overwhelming at times, she said. Even those of us who work for Access Allegany who read our bus schedules quite regularly, its sometimes hard for even us to figure out, so the average consumer might not have any idea how to read it.

Some of our routes, depending on where you start and where you want to end up, you might have to transfer to another bus, maybe even two other buses, and it tells you exactly all of that information," Cooper said. "You dont have to think about it. You dont have to figure it out.

Google Maps is also a program familiar to many people. According to Google, more than a billion people use Google Maps every month and more than 5 million active apps and websites are using Google Maps Platform core products every week.

To get started, open Google Maps and click the Directions arrow. This will provide several travel options at the top of the screen, including flight, cycling, walking, driving and transit, which is represented by a bus icon.

So if youre searching for a public transportation route in Allegany County, you pick that bus icon, Cooper said.

Then type in where you want to start your trip and the trip's destination. Hit search, and all routes meeting that need willbe shown. From there, select the route that works best for you.

To see the stops in a route and other information, click on Details. It calculates the distance to a bus stop as well as the time the bus will arrive and drop you off. Clicking on the "Details" will also let you know the service area of the bus and the bus number.

Additional Travel Information and Options" include a Leave Now tab, which allows the user to select the timing of the trip.

Additional features include the capability to send trip directions to a Google account and to see a breakdown of all the times available for a trip, which means riders can plan transportation hours or days ahead of time.

Allegany County owns Access Allegany, supplying funding for the fixed-route public transit system that runs five buses in six service areas, Monday throughFriday.

Allegany County contracts with First Transit to operate the system, while Ardent Solutions has the contract to provide the management.

Cooper, who works for Ardent Solutions, said it was a 14-month process involving a great deal of trial and error to meet Google Transits exacting requirements.

They are super meticulous, she explained. Obviously, they hold the market on any sort of mapping software thats out there. Theyre very responsive. They followed up. They were understanding if it was going to take some time to update the GTFS file."

Close enough was not adequate when it came to providing Google Transit with route locations and stop placements.

Cooper said, We had a couple issues with route locations, and theyre very specific about where the stop is placed.

For example, if theyre pulling up outside the Episcopal church in Wellsville which is a stop thats utilized quite often for our riders, within the files that stop has to be on the sidewalk or the side of the road.

When you get into some of these software programs, you think you are at the right spot, but Google Maps would pull it up and it would show the middle of the road, so theyre very meticulous because theyre like, Nobodys going to catch a bus in the middle of the road.

Access Allegany is just beginning to get the word out about its availability on Google Maps. Marketing materials are coming together and a big Facebook push is planned. Customer training sessions are also in the works.

Many riders continue to contact the call center at 585-593-1738 and call center staff now have Google Maps at their disposal to help riders plan trips.

Cooper acknowledged that COVID-19 has decreased business, but she said Access Alleganys ridership numbers are consistent with national averages for mass transit systems. She said Access Allegany tracks ridership numbers daily and the focus is always on improvement.

Ultimately our goal is to increase our ridership and make this an accessible option for anybody in our community that needs transportation, Cooper said.

Do we create space-time? A new perspective on the fabric of reality – New Scientist

Posted: at 3:41 pm

By Amanda Gefter

Mary Iverson

IMAGINE approaching a Renaissance sculpture in a gallery. Even from a distance, it looks impressive. But it is only as you get close and walk around it that you begin to truly appreciate its quality: the angle of the jaw, the aquiline nose, the softness of the hair rendered in marble.

In physics, as in life, it is important to view things from more than one perspective. As we have done that over the past century, we have had plenty of surprises. It started with Albert Einsteins theory of special relativity, which showed us that lengths of space and durations of time vary depending on who is looking. It also painted a wholly unexpected picture of the shared reality underneath one in which space and time were melded together in a four-dimensional union known as space-time.

When quantum theory arrived a few years later, things got even weirder. It seemed to show that by measuring things, we play a part in determining their properties. But in the quantum world, unlike with relativity, there has never been a way to reconcile different perspectives and glimpse the objective reality beneath. A century later, many physicists question whether a single objective reality, shared by all observers, exists at all.

Now, two emerging sets of ideas are changing this story. For the first time, we can jump from one quantum perspective to another. This is already helping us solve tricky practical problems with high-speed communications. It also sheds light on whether any shared reality exists at the quantum level. Intriguingly, the answer seems to be no until we start talking to each other.

When Einstein developed his theory of relativity in the early 20th century, he worked from one fundamental assumption: the laws of physics should be the same for everyone. The trouble was, the laws of electromagnetism demand that light always travels at 299,792 kilometres per second and Einstein realised this creates a problem. If you were to race alongside a light beam in a spaceship, you would expect to see the beam moving far slower than usual just as neighbouring cars dont look to be going so fast when you are zipping along the motorway. Yet if that was the case, the laws of physics in that perspective would be violated.

Einstein was convinced that couldnt happen, so he was forced to propose that the speed of light is constant for everyone, regardless of how fast they are moving. To compensate, space and time themselves had to change from one perspective to the next. The equations of relativity allowed him to translate from one observers perspective, or reference frame, to another, and in doing so build a picture of the shared world that remains the same from all perspectives.

He went on to develop these ideas into general relativity, which remains our best theory of gravity. But it isnt the whole story. In Einsteins writings, reference frames are always defined by rods and clocks, physical objects against which space and time are measured. These objects are, however, governed by a different theory altogether.

Quantum theory deals with matter and energy and is even more successful than relativity. But it paints a deeply unfamiliar picture of reality, one in which particles dont have definite properties before we measure them, but exist in a superposition of multiple states. It also shows that particles can become entangled, their properties intimately linked even over vast distances. All this puts the definition of a reference frame on shaky ground. How do you measure time with a clock that is entangled, or distance with a ruler that is in multiple places at once?

How do you measure time with a clock that is entangled, or distance with a ruler that is in multiple places at once?

Quantum physicists usually avoid this question by treating measuring instruments as if they obey the classical laws of mechanics developed by Isaac Newton. The particle being measured is quantum; the reference frame isnt. The dividing line between the two is known as the Heisenberg cut. It is arbitrary and it is moveable, but it has to be there so that the measuring device can record a definite result.

Consider Schrdingers cat, the thought experiment in which an unfortunate feline is in a box with a radioactive particle. If the particle decays, it triggers a hammer that breaks a vial that releases a poison that kills the cat. If it doesnt, the cat lives. You are outside the box. From your perspective, the contents are entangled and in a superposition. The particle both has and hasnt decayed; the cat is both dead and alive. But, as in relativity, shouldnt it be possible to describe the situation from the perspective of the cat?

This conundrum has long bothered aslav Brukner at the Institute for Quantum Optics and Quantum Information in Vienna, Austria. He wanted to understand how to see things from multiple points of view in quantum theory. Following Einsteins lead, he started from the assumption that the laws of physics must be the same for everyone, and then developed a way to mathematically switch between quantum reference frames. If we could describe a situation from either side of the Heisenberg cut, Brukner suspected that some truth about a shared quantum world might emerge.

What Brukner and his colleagues found in 2019 was a surprise. When you jump into the cats point of view, it turns out that just as in relativity things have to warp to preserve the laws of physics. The quantumness previously attributed to the cat gets shuffled across the Heisenberg cut. From this perspective, the cat is in a definite state it is the observer outside the box who is in a superposition, entangled with the lab outside. Entanglement was long thought to be an absolute property of reality. But in this new picture, it is all a matter of perspective. What is quantum and what is classical depends on the choice of quantum reference frames, says Brukner.

Jacques Pienaar at the University of Massachusetts says all this allows us to rigorously pose some fascinating questions. Take the well-known double-slit experiment, which showed that a quantum particle can travel through two slits in a grating at once. We see that, relative to the electron, it is the slits themselves that are in a superposition, says Pienaar. To me, thats just wonderful. While that might all sound like mere theorising, one thing that gives Brukners ideas credence is that they have already helped solve an intractable problem relating to quantum communication (see Flying qubits).

Quantum reference frames do have an Achilles heel though, albeit one that might ultimately point us to a deeper appreciation of reality. It comes in the form of Wigners friend, a thought experiment dreamed up in the 1950s by physicist Eugene Wigner. It adds a mind-bending twist to Schrdingers puzzle.

Faced with the usual set-up, Wigners friend opens the box and finds, say, that the cat is alive. But what if Wigner himself stands outside the lab door? In his reference frame, the cat is still in a superposition of alive and dead, only now it is entangled with the friend, who is in a superposition of having-seen-an-alive-cat and having-seen-a-dead-cat. Wigners description of the cat and the friends description of it are mutually exclusive, but according to quantum theory they are both right. It is a deep paradox that seems to reveal a splintered reality.

Brukners rules are no help here. We cant hop from one side of the Heisenberg cut to the other because the two people are using different cuts. The friend has the cut between herself and the box; Wigner has it between himself and the lab. They arent staring at each other from across the classical-quantum divide. They arent looking at one another at all. My colleagues and I were hoping that the Wigners friend situation could be rephrased in quantum reference frames, says Brukner. But so far, that hasnt been possible. I dont know, he sighs. Theres a missing element.

Hints as to what that might be are coming from work by Flavio Mercati at the University of Burgos in Spain and Giovanni Amelino-Camelia at the University of Naples Federico II in Italy. Their research seems to suggest that by exchanging quantum information, observers can create a shared reality, even if it isnt there from the start.

The duo were inspired by research carried out in 2016 by Markus Mller and Philipp Hhn, both then at the Perimeter Institute in Waterloo, Canada, who imagined a scenario in which two people, Alice and Bob, send each other quantum particles in a particular state of spin. Spin is a quantum property that can be likened to an arrow that can point up or down along each of the three spatial axes. Alice sends Bob a particle and Bob has to figure out its spin; then Bob prepares a new particle with the same spin and sends it back to Alice, who confirms that he got it right. The twist is that Alice and Bob dont know the relative orientation of their reference frames: ones x-axis could be the others y-axis.

Alice and Bobs communication may forge the structure of space-time

If Alice sends Bob just one particle, he will never be able to decode the spin. Sometimes in physics, two variables are connected in such a way that if you measure one precisely, the other no longer exists in a definite state. This tricky problem, known as the Heisenberg uncertainty principle, applies to particles spin along different axes. So if Bob wants to measure spin along what he thinks is Alices x-axis, he has to take a wild guess as to which axis that really is if he is wrong, he erases all the information. The pair can get around this, however, if they exchange lots of particles. Alice can tell Bob, Im sending you 100 particles that are all spin up along the x-axis. As Bob measures more and more of them, he can begin to work out the relative orientation of their reference frames.

Here is where it gets interesting. Mller and Hhn realised that, in doing all this, Alice and Bob automatically derive the equations that enable you to translate the view from one perspective to another in Einsteins special relativity. We tend to think of space-time as the pre-existing structure through which observers communicate. But Mller and Hhn flipped the story. Start with observers sending messages, and you can derive space-time.

For Mercati and Amelino-Camelia, who first came across the work a few years ago, that flip was a light-bulb moment. It raised a key question that turns out to have a crucial bearing on Brukners work: are Alice and Bob learning about a pre-existing space-time or is the space-time emerging as they communicate?

There are two ways in which the latter could play out. The first has to do with the trade-off in quantum mechanics between information and energy. To gain information about a quantum system you have to pay energy, says Mercati. Every time Bob chooses the correct axis, he loses a bit of energy; when he chooses wrong and erases Alices information, he gains some. Because the curvature of space-time depends on the energy present, when Bob measures his relative orientation he also ends up changing the orientation a tiny bit.

There could be a more profound sense in which quantum communication creates space-time. This comes into play if space is whats called non-commutative. If you want to arrive at a point on a normal map, it doesnt matter in which order you specify the coordinates. You can go over five and up two; or up two and over five either way you will land on the same spot. But if the laws of quantum mechanics apply to space-time itself, this might not be true. In the same way that knowing a particles position prevents you from measuring its momentum, going over five might prevent you from going up two.

Mercati and Amelino-Camelia say that if space-time does work in this way, Alice and Bobs attempts to find out their relative orientation wouldnt merely uncover the structure of space-time, they would actively forge it. The choices they make as to which axes to measure would alter the very thing their communication was meant to reveal. The pair have also devised a way to test whether this is really the case (see Does space-time commute?).

All this work points towards a startling conclusion: that as people exchange quantum information, they are collaborating to construct their mutual reality. It means that if we simply look at space and time from one perspective, not only do we miss its full beauty, but there might not be any deeper shared reality. For Mercati and Amelino-Camelia, one observer does not a space-time make.

That leads us back to the Wigners friend paradox that flummoxed Brukner. In his work, observers can be treated as having perspectives on the same reality only when they are gazing at one another from across the Heisenberg cut. Or, put another way, only when it is possible for them to communicate, which is precisely what Wigner and his friend cant do. Perhaps this is telling us that until two people interact, they dont share the same reality because it is communication itself that creates it.

Networks of cables that carry quantum information are already being set up around the world as a prototype quantum internet. These networks transport information in the form of qubits, or quantum bits, which can be encoded in the properties of particles typically in a quantum property called spin. One person sends a stream of particles to another, who then measures their spin to decode the message.

Except, not so fast. To be a useful means of communication, these particles must travel at close to the speed of light. At such speeds, a particles spin gets quantum entangled with its momentum in such a way that if the receiver only measures the spin, information will be lost. This is serious, says Flaminia Giacomini at the Perimeter Institute in Canada. The qubit is the basis for quantum information, but for a particle moving at very high velocities, we can no longer identify a qubit. As if that werent enough of a problem, each qubit doesnt move at one definite speed: thanks to quantum mechanics, it is in what is known as a superposition of velocities.

The rules of quantum reference frames developed by aslav Brukner (see main story) could be the answer. Giacomini has shown how the rules can be used to jump into the particles reference frame, even when the particle is in a superposition. From that perspective, it is the rest of reality that is whizzing past in a blurred superposition. Armed with knowledge of how the qubit sees the world, you can then determine the mathematical transformation to perform on the particle to recover the information in the original qubit.

In ordinary space, it isnt the journey that matters so much as the destination. If youre trying to arrive at a given place, it makes no difference whether you head 5 kilometres south and then 3 kilometres west, or vice-versa. That is because the coordinates commute; they get you to the same spot regardless of the order.

At very small scales to which quantum theory applies, this might not be true. In quantum theory, measuring a particles position erases information about its momentum. Similarly, it could be that the order in which movements are made could affect the structure of space. If this is so, it makes no sense to talk about space-time as a fixed arena.

Physicists Flavio Mercati and Giovanni Amelino-Camelia think they have a way to find out whether space-time commutes. They were inspired by research that imagined two people exchanging quantum particles and measuring their properties to deduce their relative orientation (see main story). What would happen, Mercati and Amelino-Camelia asked, if this game were played for real?

As the people exchange more and more particles, their uncertainty about their orientation should decrease. But will it ever get to zero? In ordinary space-time, it will. But if space-time is non-commutative, some uncertainty will always remain, since their orientation is ever so slightly rewritten with each measurement. The pair might have to exchange trillions of particles before we will have an answer but Mercati thinks it is worth a try.

Let Me Google That for You: A Recent Central District of Illinois Opinion Highlights the Limits of Googling by Expert Witnesses Under Rule 702 and…

Posted: at 3:41 pm

While we all rely on Google or other internet search engines to find and absorb information quickly these days, a recent decision in the Central District of Illinois highlights the problems for expert witnesses relying on internet research as a methodology. See Sherman v. BNSF Railway Co., Case No. 1:17-cv-01192, 2022 WL 138630 (C.D. Ill. Jan. 14, 2022). While Googling is likely a practice that many experts may engage in (though may be loathe to admit it), Google searching alone is a suspect methodology upon which to base expert opinions.

In Sherman, Plaintiff sued Defendant BNSF Railway Co. (BNSF) pursuant to the Federal Employers Liability Act, alleging that during her employment with BNSF, she was exposed to toxic substances and carcinogens, including asbestos, that caused her to develop rectal cancer.

BNSF moved to exclude Plaintiffs medical causation expert. In relevant part, BNSF attacked the experts methodology in arriving at his general causation conclusion that asbestos could cause rectal cancer. During his deposition, the expert testified that in reaching his opinions on certain chemicals and rectal cancer, his general approach is to do a Google search, and thats what I did in this case as well..

BNSF argued that the experts methodology was unreliable, in that he did not retain a list of what he viewed and what information he considered, he has no record of when the Google search was performed, what search terms he used, which sites he looked at, which articles he looked at, and what information he considered and discarded or why.

The Sherman court agreed, noting that the experts methodology his Google search seriously lacks indicia of reliability. In fact, the court noted that the experts methodology is so lacking that it would be nearly useless to apply the non-exhaustive Daubert factors to it in order to determine its reliability. In excluding the experts testimony, the court reasoned that it was entirely precluded from finding [the experts] methodology was reliable where he did not keep any record whatsoever of the particulars of his Google search, including the simple fact of the date(s) on which he performed his Google searches. Significantly, it would be essentially impossible for defense counsel to effectively cross-examine [the expert] at trial without knowing the particulars of [his] Google searches, specifically any information he reviewed and rejected and the reasons for doing so.

Plaintiff tried to resuscitate her expert, noting that his opinions were reliable because he drew from his extensive knowledge, training, and experience as a medical oncologist, he undertook a review of the available literature, considering both positive and negative evidence, and he reviewed publications of authoritative bodies. The court rejected this, noting that [t]he fact that [the expert] purportedly applied his knowledge, training, and experience to the existing data he reviewed does not eliminate the shortcoming that the full extent of that data is not known.

Sherman is obviously not the first case to exclude an expert for failure to conduct a reliable literature review. See e.g., In re Lipitor (Atorvastatin Calcium Marketing, Sales Pracs. and Prods. Liab. Litig., 174 F. Supp. 3d 911, 935 (D.S.C. 2016) (finding that it was not a valid methodology where expert had no explanation for how she identified [medical literature] for her consideration and that she could not simply pick the articles that she happened to remember or that supported her views, discuss them with a little commentary, and state an opinion). Nor is it even the first case to find that conducting Google searches does not an expert make. See e.g. Price v. LOreal USA, Inc., 2020 WL 4937464, at *4 (S.D.N.Y. Aug. 24, 2020) (where expert opinion that ingredient in hair products was well known to consumers was based on certain Google searches among other document review, and where expert didnt list every article that [he] saw during those searches, his methodology was unreliable because [w]ithout a record of the materials reviewed, [the experts] methodology cannot be tested, challenged or replicated); Wai Feng Trading Co. Ltd., v. Quick Fitting, Inc., 2018 WL 6726557, at *10 (D.R.I. Dec. 21, 2018) (holding that expert methodology was rooted in guesswork and unhelpful under Rule 702 where expert noted that his methodology was based in part on online searching and Google, although he was unable to say what this research revealed); see also Toffoloni v. LFP Pub. Group, LLC, 2010 WL 4877911, at *2 (N.D. Ga. Nov. 23, 2010) (excluding damages experts opinion as unreliable in case where plaintiff sought damages for publication of unauthorized photographs; plaintiffs expert calculated the value of the photographs based on researching the value of the publication of another public figures photographs, and concluded plaintiffs images were worth more because [she] was a bigger celebrity based . . . on Google search results).

However, Sherman is a good reminder of the necessity to be ready to support your experts literature search, and also to challenge the search methodology of any opposing expert. A reliable literature review uses formal search methods to allow a researcher to obtain a neutral snapshot of the existing research on a particular question. In re Lipitor, 174 F. Supp. 3d at 929. In addition to relying on formal search methods beyond Google (e.g. searches of academic and/or scientific databases), an expert should document his or her literature searches and materials reviewed. Likewise, an expert should be prepared to describe the method of his or her searches at deposition, including how certain material was chosen to rely on and how certain material was distinguished by the expert. While your expert still may want to utilize Google in part, relying solely on Google searches and failing to document them could lead to the opinions based on those searches or the experts entire testimony to be excluded. The Sherman opinion does not say whether the excluded expert used Googles Im Feeling Lucky button for his searches, but his luck ran out when he was required to show his work.
