Albert Einstein was born in Ulm, Germany in 1879. As a child, he was fascinated by a compass and wanted to understand the invisible forces that guided it. In 1905, while working as a patent clerk in Germany, Einstein developed his Special Theory of Relativity and introduced the world to the idea that light exists as particles called photons. He went on to publish additional groundbreaking papers that year, including his famous equation E=mc2. Einstein later completed his General Theory of Relativity in 1915, which revolutionized the scientific understanding of gravity. He died in 1955 in Princeton, New Jersey at the age of 76, leaving behind a transformed scientific world.
