Quantum Randomness Gives Nature Free Will

Whether or not quantum randomness explains how our brains work, it may help us create unbreakable encryption codes

When I was boy, my father explained free will and predestination to me: I dig a fence post hole. · Did I create the hole because of my own free will? · Or was the hole already there and I simply removed the dirt? If true, the hole was predestined. The question cannot be answered by examining the evidence. In philosophy terms, it is “empirically unanswerable.” That is the sort of stuff that philosophers debate. Religious people might point to scripture to support one conclusion over the other.1 In physics, however, quantum randomness offers a definitive answer to the question of predestination vs. free will—for subatomic particles. In the world of classical physics (Isaac Newton’s physics), it can be argued Read More ›

As long as computers simply get faster and use more memory, there is no reason to worry about a self-aware Skynet. Read More ›
