E=mc²: Einstein's 'Miraculous Year' Rewrites Physics

A patent clerk publishes four papers that overturn Newton's universe

In 1905, Einstein published four revolutionary papers while working as a patent clerk, including special relativity and E=mc², transforming our understanding of the universe.

In 1905, a 26-year-old Swiss patent clerk named Albert Einstein published four papers in a single year that fundamentally transformed physics. Working without a university position, without a laboratory, and largely without colleagues to bounce ideas off, he solved problems that had stumped the greatest physicists of his generation.

The first paper explained the photoelectric effect by proposing that light was made of discrete energy packets (photons) — work that would win him the Nobel Prize. The second explained Brownian motion and provided decisive evidence for the existence of atoms. The third introduced special relativity, redefining space and time as a unified fabric that changes with motion.

The fourth paper, a three-page addendum to the relativity paper, contained the equation E=mc² — energy equals mass times the speed of light squared. This equation revealed that mass and energy were interchangeable, that matter contained almost unimaginable amounts of energy, and that the Sun's power came from converting matter into energy.

Einstein published these papers while working six days a week at the patent office, writing physics in the evenings. He was so obscure that when he…

💡 When Einstein submitted his special relativity paper, he included no references to other scientists' work — he had independently derived everything from first principles.
