albert einstein

Albert Einstein (1879–1955) was a German-born theoretical physicist whose work revolutionized our understanding of the universe. In 1905 he introduced special relativity—famously encapsulating mass–energy equivalence as E=mc²—and in 1915 published general relativity, describing gravity as spacetime curvature. He earned the 1921 Nobel Prize for explaining the photoelectric effect, helping to launch quantum theory, and remained a passionate advocate for peace and global cooperation.
