What did Albert Einstein Discover?

photoelectric effect

He is also known for his discovery of the photoelectric effect, for which he won the Nobel Prize for Physics in 1921. Einstein developed a theory of special and general relativity, which helped to complicate and expand upon theories that had been put forth by Isaac Newton over 200 years prior.

=> Brownian movement, or the zigzag motion of microscopic particles in suspension. Einstein's findings helped to prove the existence of atoms and molecules.

=> The quantum theory of light. Einstein proposed that light is composed of separate packets of energy, called -- quanta or photons -- that have some properties of particles and some properties of waves. He also explained the photoelectric effect, which is the emission of electrons from some solids when they're struck by light. Television is a practical application of Einstein's theory of light.

=> The special theory of relativity. Einstein explained that time and motion are relative to their observers -- as long as the speed of light remains constant and natural laws are the same throughout the universe.

=> The link between mass and energy. The fourth paper expanded on this idea with the famous equation E = mc2, relating mass and energy. This formula demonstrates that a small particle of matter contains an enormous amount of energy. This forms much of the basis for nuclear energy.
