Historical Context — The 1900s

The atomic age dawned as Einstein published his four revolutionary 1905 papers — special relativity, the photoelectric effect, Brownian motion, and mass-energy equivalence — in a single annus mirabilis. The Wright Brothers achieved powered flight just two years earlier, Picasso was reinventing painting with Cubism, and Freud's Interpretation of Dreams had just appeared. The world stood at the threshold of a century that would be defined by physics, technology, and mass destruction.
