General theory of relativity
- In 1915 he published his general theory of relativity, which was confirmed experimentally during a solar eclipse in 1919 with observations of the deflection of light passing near the Sun. He received a Nobel Prize in 1921 for his work on the photoelectric effect, his work on relativity still being controversial.

In his four papers, published in November 1915, Einstein laid the foundation of the theory. In the third in particular he used general relativity to explain the precession of the perihelion of Mercury. The point at which Mercury has its closest approach to the Sun, its perihelion, moves.

For almost four years after positing that gravity and acceleration were equivalent, Einstein did little with the idea. Instead he focused on quantum theory. But in 1911, when he had finally breached the walls of academia and become a professor at the German Charles-Ferdinand University in Prague, he turned his attention back to coming up with a the...
By then, he had moved to Berlin to become a professor and member of the Prussian Academy. But he found himself working pretty much without support. Anti-Semitism was rising, and he formed no coterie of colleagues around him. He split with his wife, Mileva Mari´c, a fellow physicist who had been his sounding board in formulating special relativity i...
The visit to Göttingen was a triumph. A few weeks later Einstein reported to a scientist friend that he “was able to convince Hilbert of the general theory of relativity.” In a letter to another colleague, he was even more effusive: “I am quite enchanted with Hilbert!” Hilbert was likewise enchanted with Einstein and with his theory, so much so tha...
Einstein wrote four letters on November 15, a Monday, that give a glimpse into his intertwined personal and professional dramas. To Hans Albert, he suggested that he would like to travel to Switzerland at Christmas to visit him. “Maybe it would be better if we were alone somewhere,” such as at a secluded inn, he said to his son. “What do you think?...
Einstein's pride was understandable. At age 36, he had produced a dramatic revision of our concept of the universe. His general theory of relativity was not merely the interpretation of some experimental data or the discovery of a more accurate set of laws. It was a whole new way of regarding reality. With his special theory of relativity, Einstein...
