Albert Einstein Albert Einstein was born in Ulm, Württemberg, Germany in 1879. His notable contributions included helping to develop the special and general theories of relativity. In 1921, he won the Nobel Prize for physics for his explanation of the photoelectric effect. Einstein is generally considered the most influential physicist of the 20th century. He died on April 18, 1955, in Princeton, New Jersey.
In 1905 Einstein published a paper that described experimental data from the photoelectric effect as being the result of light energy being carried in discrete quantized packets. This led to the quantum revolution and later earned him his Nobel Prize.
In the 1920s, he studied in the area of unified field theories, continuing to work on the quantum theory. Einstein won the Nobel Prize for Physics in 1921 "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect." In the photoelectric effect, electrons are emitted from liquids, solids or gases when they absorb energy from light. Electrons emitted in this manner can be called photoelectrons. Einstein also contributed to statistical mechanics by his development of the quantum theory of a monatomic gas.
In the 1920s, Einstein propelled the new science of cosmology. His equations predicted that the universe is dynamic. It is ever changing. This contradicted the popular view that the universe was static. That was the view that Einstein held earlier and was a guiding factor in his development of the general theory of relativity. In 1929, astronomer Edwin Hubble discovered that the universe was indeed expanding, thus confirming Einstein's work.
On April 2, 1921, Einstein visited New York City for the first time, where he received an official welcome by Mayor John Francis Hylan. He then lectured and went to receptions for three weeks. He went on to deliver several lectures at Columbia University
