John Archibald Wheeler

John Archibald Wheeler was an American theoretical physicist. He was largely responsible for reviving interest in general relativity in the United States after World War II. Wheeler also worked with Niels Bohr to explain the basic principles of nuclear fission. Together with Gregory Breit, Wheeler explored positron-electron pair production from the collision of two photons, now known as the Breit–Wheeler process. He is known for popularizing the term "black hole" to describe the gravitationally completely collapsed objects predicted by general relativity. He also coined "quantum foam", "neutro
