A very important consequence of relativity is the relation between mass and energy. Einstein's postulate that the speed of light should appear the same to everyone implied that nothing could be moving faster than light. What happens is that as energy is used to accelerate a particle or a...
Einstein continued to work on the quantum idea into the 1920s but was deeply disturbed by the work of Werner Heisenberg in Copenhagen, Paul Dirac in Cambridge and Erwin Schrodinger in Zurich, who developed a new picture of reality called quantum mechanics. No longer did tiny particles have a definite...
The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological--technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of...
Einstein could never accept that the universe was at its heart a cosmic crapshoot, so that today his papers on unified field theory seem hopelessly archaic. But the puzzle they tried to solve is utterly fundamental. In simply recognizing the problem, Einstein was so daringly far-sighted that only now...
