Albert Einstein

Albert Einstein (1879–1955) is the closest thing science has to a household saint — the wild-haired genius whose name is a synonym for genius itself. What's less well known is that his revolution began not in a university, but at a desk in a Swiss patent office, where the 26-year-old clerk, rejected for academic jobs, did physics in his spare moments.

The miracle year

In a single burst in 1905 — his annus mirabilis — Einstein published four papers that each could have made a career. He explained Brownian motion (nailing down that atoms are real), launched special relativity (space and time bend to keep the speed of light constant), gave the world E = mc^2 (the mass–energy equivalence), and explained the photoelectric effect by proposing that light comes in packets — quanta. It was that last, most reluctant idea — not relativity — that won him the 1921 Nobel Prize and helped ignite quantum physics.

God, dice, and a declined presidency

The great irony of Einstein's life is that the quantum world he helped create unsettled him deeply. Its built-in randomness offended him — "God does not play dice with the universe," he insisted — and he spent his later years arguing (and losing) against it. He was also, famously, a reluctant celebrity: he did poorly at rote schooling, couldn't be bothered to memorise his own phone number ("why memorise what you can look up?"), and in 1952 politely declined an offer to become President of Israel, explaining he had no head for people, only for equations. The patent clerk never quite got used to being an icon.
