During his spare time as a young technical officer in a Swiss patent office in 1905, he produced three papers that changed science forever. The first, for which he was later to win the Nobel Prize, described how light could behave not only like a wave but also like a stream of particles, called quanta or photons. This wave-particle duality became the foundation of what is known as quantum physics. It also provided theoretical underpinnings for such 20th century advances as television, lasers and semiconductors...
...young clerk named Albert Einstein, working in the Swiss Patent Office in Bern, who cut through the ether and solved the speed-of-light problem once and for all. In June 1905 he wrote one of three papers that would establish him as one of the world's leading scientists--and in the process start two conceptual revolutions that changed our understanding of time, space and reality...
Einstein was aware of this difficulty in 1907, while he was still at the patent office in Bern, but didn't begin to think seriously about the problem until he was at the German University in Prague in 1911. He realized that there is a close relationship between acceleration and a gravitational field. Someone in a closed box cannot tell whether he is sitting at rest in the earth's gravitational field or being accelerated by a rocket in free space. (This being before the age of Star Trek, Einstein thought of people in elevators rather than spaceships...
...certain size, called quanta. It was as if radiation were packaged like sugar; you cannot buy an arbitrary amount of loose sugar in a supermarket but can only buy it in 1-lb. bags. In one of his groundbreaking papers written in 1905, when he was still at the patent office, Einstein showed that Planck's quantum hypothesis could explain what is called the photoelectric effect, the way certain metals give off electrons when light falls on them. This is the basis of modern light detectors and television cameras, and it was for this work that Einstein was awarded...
...first patent, for an electric vote recorder, taught him a lesson that would guide the rest of his career. There was no demand, at the time, for electric vote recorders, and his device earned him nothing. Edison vowed never again to invent something unless he could be sure it was commercially marketable...
