In classical physics, everything is mechanistic, pre-determined and, therefore, predictable and controlled, in a world where sensory experiences are perceived as reality. But quantum physics says that pre-determined behaviour could be subject to change when there is molecular uncertainty. Are we products of the determinate variables in particle physics and so live a pre-destined, pre- determined life? Or could we exercise free will and change things?

George Ellis, professor in the department of mathematics, University of Cape Town, says that while on the one hand we talk of the predictable, mechanistic universe that classical physics is premised on, on the other hand, we have quantum physics at the micro level, where Heisenbergs Uncertainty Principle overturns the theory of determinism. A mechanistic universe with a physically determined trajectory may submit to uncertainties where nothing can be predicted with certainty.

In the biological universe too, it is not only physical DNA that determines lifes trajectory. Yes, scientists did discover that the DNA molecule contains codes that indicate our genetic inheritance from our forefathers. Yet, it is seen that not all those who are carrying information that predisposes them to specific conditions show evidence of its manifestation. Why?

This is because there are other parameters and changing conditions that come into play, like nurture, the environment, mental attitude and free will. This is what spiritual masters call the art of altering your karma through exercise of free will, you could redesign your destiny.
