A physicist whose work connects special relativity, general relativity, Brownian motion and the photoelectric effect. He worked at the Institute for Advanced Study from 1933 until his death in 1955.[ref]

In 1905, Albert Einstein used the photoelectric effect to explore quantized light, related Brownian motion to molecular agitation, formulated special relativity, and connected changes in mass and energy. These problems link visible measurements to otherwise inaccessible structure: emitted Electron energies, suspended-particle displacements and comparisons of clocks.[ref]

The Millikan photoelectric experiment follows one of those predictions into the laboratory. Its stopping-voltage measurements test a quantitative relation; the experiment's apparatus, surface preparation and electrical corrections matter to that inference. The Einstein field equations and general relativity lead to a different set of tests involving gravity and spacetime.
The Nobel Prize in Physics in 1921 recognized his theoretical work, particularly the law of the photoelectric effect; the award was presented in 1922.[ref]

Albert Einstein was a theoretical physicist, best known for developing the theory of relativity, which revolutionized our understanding of space, time, and gravity. Born on March 14, 1879, in Ulm, Germany, he later became a Swiss citizen and eventually settled in the United States. Einstein's most famous equation, \(E = mc^2\), expresses the equivalence of mass and energy and is a cornerstone of modern physics.
