...Crick be Persons of the Century? Perhaps. But two factors count against them. Their role, unlike that of Einstein or Churchill, would have been performed by others if they hadn't been around; indeed, competitor Linus Pauling was just months away from shouting the same eureka!. In addition, although the next century may be, this did not turn out to be a century of genetic engineering...
Fleming, Watson and Crick, the Wright Brothers, Farnsworth, Turing, Shockley, Fermi, Oppenheimer, Noyce--any of them could be, conceivably, a justifiable although somewhat narrow choice for Person of the Century. Fortunately, a narrow choice is not necessary...
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, it explained why one was possible. He also helped resolve smaller mysteries, such as why the sky is blue (it has to do with how the molecules of air diffuse sunlight...
...Although the theory of relativity fit well with the laws that govern electricity and magnetism, it wasn't compatible with Newton's law of gravity. This law said that if you changed the distribution of matter in one region of space, the change in the gravitational field would be felt instantaneously everywhere else in the universe. Not only would this mean you could send signals faster than light (something that was forbidden by relativity), but it also required the Absolute or Universal Time that relativity had abolished in favor of personal or relativistic time...
...existence of up to seven dimensions in addition to the by now familiar four (height, width, length and time). It also requires the existence of an entirely new class of subatomic particles, known as supersymmetric particles, or "sparticles." Moreover, there isn't just one string theory but five. Although scientists could rule out none of them, it seemed impossible that all of them could be right...
