In 1915, Albert Einstein stunned physicists worldwide when he connected energy, matter, and the speed of light with his mind-blowing equation E=mc2. This mathematical expression of General Relativity placed time as the fourth dimension in the interaction of space and matter. Einstein’s visionary thinking did not stop here! He postulated that all relationships between time, forces, and particles — regardless of size and distance — could be described by one mathematical theory. He believed that this “Unified Field Theory” would predict electromagnetic forces between electrons and protons in atoms, gravitational fields between suns and orbiting planets in galaxies, and the curvature of space and time in the universe.
From the 1920s until his death in 1955, Einstein worked tirelessly to solve the equations which would prove his theory. He was unsuccessful yet never gave up. While preparing a lecture, his aorta ruptured from an aneurism. From his hospital bed and in excruciating pain from internal bleeding, he requested his notebook be brought to him so he could continue his work. He died the next day at age 76.
