Is everything pre-decided? "There is nowhere in the universe where the laws of physics are violated." Considering this general to be true,can i conclude that everything is pre-decided? I can explain this in the following manner: consider a photon or nerve impulse travelling in our brain at this exact moment,in accordance with the above theory, it will meet a definite fate determinable by sufficiently complex physical calculations, i.e strike a particular nerve ending and thus initiate a chain of thoughts which lead to a definite action on our part and thus determine future. Thus it can be essentially conclude that every particle or wave in the universe will necessarily follow the laws of Newtonian or quantum physics at every point of time and thus the future is definite and pre-decided. Please express your views. 
 A: This is false:

Thus it can be essentially conclude that every particle or wave in the universe will necessarily follow the laws of Newtonian or quantum physics at every point of time and thus the future is definite and pre-decided. 

When quantum mechanics enters the brew, by the physical laws that follow it everything is probabilistic and thus not predetermined

The mathematical formulations of quantum mechanics are abstract. A mathematical function known as the wavefunction provides information about the probability amplitude of position, momentum, and other physical properties of a particle

Adding that a mole of matter consists  of about  10^23 atoms/molecules, even if only Newtonian physics existed the many body problem would be intractable anyway by any computational method; again one  would rely on statistical distributions and probabilities. In any case, the underlying quantum mechanical level from which every measurable physical quantity emerges is probabilistic, not predetermined.
