Albert Einstein
Life
Not a mathematician but a physicist — yet to build general relativity (1915), the theory that spacetime itself is curved, he had to spend three years studying Riemannian geometry with his friend Marcel Grossmann. He thereby showed that mathematics itself is the universe's native language. His 1921 Nobel Prize was for the photoelectric effect — the committee found relativity too mathematical to honor.
Decisive moments
Annus mirabilis — four papers at 26
BernAs a clerk at the patent office he produced four papers in a single year — photoelectric effect, Brownian motion, special relativity, E = mc² — rewriting physics in one sweep.
General relativity — the curvature of spacetime
BerlinAfter 8 years of struggle in Berlin, the field equation G_μν = 8πT_μν: gravity is the curvature of spacetime. Confirmed by the 1919 eclipse observation of bending starlight, he became a global celebrity overnight.
Fleeing the Nazis to America
PrincetonWhen Hitler rose, he emigrated to the U.S. and settled at Princeton's Institute for Advanced Study. He spent the rest of his life chasing a unified field theory — and never finished it.
