...their relationship described by the most famous equation in all of physics: energy equals mass multiplied by the speed of light squared, E=mc2. Although not exactly a recipe for an atomic bomb, it explained why one was possible. He also helped resolve smaller mysteries, such as why the sky is blue (it has to do with how the molecules of air diffuse sunlight...

For the rest, the day began at dawn, noon was when the sun was highest in the sky, and sunset wrapped things up. Says Carleen Stephens, who curated the Smithsonian show, in 1790 fewer than 10% of Americans had a clock of any kind in their homes, and most of those had no minute hand...
