No. There was once a powerful argument against free will based on the supposed “determinism” of the laws of physics, but this determinism was overthrown by quantum mechanics in the 1920s. “Physical determinism” is the idea that the laws of physics uniquely determine how any physical system will develop over time. In the 19th century, this appeared to be correct, because all the physical laws that had been discovered, such as Newton’s laws of mechanics and gravity, had deterministic equations. It was widely expected that this would also turn out to be true of the complete laws of physics. Consequently, many people began to doubt the reality of free will. source Unverified
