On how the world-famous physicist Albert Einstein and Henri Poincaré, a well-known nineteenth-century mathematician and theoretical physicist, were able to develop the insights that led to their groundbreaking discoveries in special relativity, which describes the motion of particles at close to the speed of light. They were both immersed in practical jobs that brought them in close contact with new developments in science and technology. Einstein's job in a patent office located him squarely in the middle of a wealth of technological developments and patents related to the coordination of clocks. Working at the Paris Bureau of Longitude, Poincaré was involved with the use of precision-coordinated clocks for long-distance longitude determination.

Around the horizon of a black hole, an edge of the universe, light is captured, spun into orbit by the black hole’s powerful gravitational pull. Lying within the orange donut in the famous first image of a black hole, this “photon ring” would be a prize...
My world was jolted by two shadow images: one, thrilling, the other terrifying. After a years-long effort—with 200 other scientists—we made the first image of a black hole, its shadow of no return. Then I fell into debilitating pain. A deadly shadow...
1930, Madras, India. On a steamship to England, 19-year-old Indian physics prodigy, Subrahmanyan Chandrasekhar makes a paradigm-shattering discovery about the life cycle of stars: a discipline pioneered by Sir Arthur Eddington, the world’s most famous...
