“Because of the chaotic quantum unpredictability of nature, our will is free from prediction.”
Consider it: The universe evolves in an unpredictable manner. We create models in science to predict, but these are always approximate. With quantum mechanics we realize events are based on probabilities rather than certainties. Particles have probabilities of where they will be found. It cannot be known where a particle is until we measure it, which affects where it is going.
