Still, the intuitive flash did not occur to any of the scientific greats of the day, but to the 26-year-old patent examiner on the fringes of physics. That insight was shown in two remarkable papers that appeared during 1905 in the German scientific journal Annalen der Physik. The title of the first ? "On the Electrodynamics of Moving Bodies" ? did not begin to reflect its eventual significance. Later it would become known as Einstein's special theory of relativity...
Einstein published two other landmark reports in Annalen der Physik during 1905. One paper explained a laboratory curiosity called the photoelectric effect, which occurs when a light beam hits a metallic target and causes it to give off electrons. (This phenomenon makes possible a host of today's electronic gadgetry, ranging from electric-eye devices to TV picture tubes and solar panels for spacecraft.) In this paper Einstein borrowed from a theory by German Physicist Max Planck, who had solved a vexing problem about the radiation of heat and light from hot objects by proposing that this radiant energy...
