jan 1, 1905 - Albert Einstein
Description:
His first paper was on the motion of particles suspended in liquid. He developed a mathematical formula to explain that the visible motion of the particles was due to the invisible motion of the molecules of the liquid. His second paper was on the photoelectric effect, or the release of electrons from metal when light shines on it. Einstein used the very recent ideas of Max Planck to explain the phenomenon.Added to timeline:
