Annus mirabilis is a Latin phrase that means “wonderful year”, “miraculous year” or “amazing year”. This term was originally used to refer to the year 1666, and today is used to refer to several years during which events of major importance are remembered.
Albert Einstein singlehandedly added 1905 as another Annus Mirabilis. In this year, his creativity peaked and he made the revolutionary scientific discoveries. He was just 26 years old. During that year he did:
March: Proved that the light consists of photons thus proving the quantum nature of the light.
May: Proved the existence of the atom.
June: Special Theory of Relativity, which forced the laws of motion by another great physicist Newton as the corollary with the objects moving at lower speeds.
November: The most conscise and beautiful equation relating mass and energy. Proving that mass and energy are two names of the same thing. That enormous amounts of energy are condensed to make small amounts of mass. In other words, enormous amounts of energy are contained in the mass.
And after that he became a superstar
