1905 was a common year starting on Sunday (see link for calendar). The year is referred to as an annus mirabilis because of the publication of several papers by Albert Einstein that lay the foundations for quantum physics, introduced the special theory of relativity, explained Brownian motion and proved the existence of atoms.
