WebFor example, under some circumstances a single particle can behave like it’s a wave and somehow spread out and interfere with itself. And under other circumstances a wave can exhibit particle-like behaviour. By about 1930 the exact rules of quantum mechanics had been clearly written down, as clearly as Newton’s three laws of motion.
