Einstein, Albert (1879-1959) German, Swiss Theoretical Physicist Albert Einstein was one of the most influential physicists of modern times. He is best known for his theory of relativity and for deriving the equivalence between mass and energy expressed as the following:
where E equals energy, m is mass, and c is the speed of light. Einstein won the Nobel Prize in physics in 1921 "for his services to theoretical physics, and especially for his discovery of the photoelectric effect." His most significant contributions include his special theory of relativity, which reconciles mechanics and electromagnetism, and the general theory of relativity, which deals with gravitation and applying the ideas of relativity to nonuniform motion. He also pioneered many contributions in cosmology, mechanics, quantum theory, light and radiation, and unified field theory. Albert Einstein authored more than 300 scientific papers and 150 other works.
