Einstein went on to show that energy and matter were merely different faces of the same thing, their relationship described by the most famous equation in all of physics: energy equals mass multiplied by the speed of light squared, E=mc2. Although not exactly a recipe for an atomic bomb...
Einstein, hitherto little known, became a global celebrity and was able to sell pictures of himself to journalists and send the money to a charity for war orphans. More than a hundred books were written about relativity within a year.
Einstein also continued his contributions to quantum physics by raising questions that are still playing a pivotal role in the modern development of the theory. Shortly after devising general relativity, he showed that photons have momentum, and he came up with a quantum theory of radiation explaining that all subatomic...
This opened the way, alas, to the quantum theories of Werner Heisenberg and others who showed how the wave-particle duality implies a randomness or uncertainty in nature and that particles are affected simply by observing them. This made Einstein uncomfortable. As he famously and frequently insisted, "God does not...
Does Einstein's discomfort with quantum theory make him less a candidate for Person of the Century? Not by much. His own work contributed greatly to quantum theory and to the semiconductor revolution it spawned. And his belief in the existence of a unified field theory could well be proved...
