Albert Einstein had wild hair, a friendly face, and a brain that rewrote physics. In 1905 he was a 26-year-old patent clerk in Switzerland when he published four papers in one year that flipped science on its head - including the idea that energy and mass are really two forms of the same thing.
His most famous theory, general relativity, said that gravity isn’t a pulling force - it’s space and time bending around heavy objects. Years later, scientists watched starlight curve around the sun during an eclipse, exactly as Einstein had predicted. He was suddenly the most famous scientist on Earth.
In 1952, Israel’s first president died and the country invited Einstein to take the job. He was honored but said no, explaining that he understood equations far better than he understood people. He kept thinking about physics - and the puzzle of one big “theory of everything” - until the very end of his life.
