2.-developed the theory of relativity.
3.-Born in Ulm, Württemberg, Germany in 1879
4.-In 1921, he won the Nobel Prize for physics for his explanation of the photoelectric effect.
5.-He died on April 18, 1955, in Princeton, New Jersey.
6.-Albert Einstein grew up in a secular, middle-class Jewish family.
7.In the 1920s, Einstein launched the new science of cosmology.
8.-his later calculations in the general theory indicated that the universe could be expanding or contracting.
9.-Einstein’s theories on relativity became a convenient target for Nazi propaganda
10.-he applied the quantum theory (developed by German physicist Max Planck) to light in order to explain the phenomenon known as the photoelectric effect, by which a material will emit electrically charged particles when hit by light.
11. -second article contained Einstein’s experimental proof of the existence of atoms, which he got by analyzing the phenomenon of Brownian motion, in which tiny particles were suspended in water.
12. -third and most famous article, titled “On the Electrodynamics of Moving Bodies,” Einstein confronted the apparent contradiction between two principal theories of physics: Isaac Newton’s concepts of absolute space and time and James Clerk Maxwell’s idea that the speed of light was a constant.
13.- fourth paper concerned the fundamental relationship between mass and energy, concepts viewed previously as completely separate. Einstein’s famous equation E =…
