Biography of physics

George Gamow (sometimes Gammoff; born Georgiy Antonovich Gamov; Russian: Гео́ргий Анто́нович Га́мов; March 4 [O.S. February 20] 1904 – August 19, 1968) was a Soviet and American polymath, theoretical physicist and cosmologist. He was an early advocate and developer of Georges Lemaître's Big Bang theory. Gamow discovered a theoretical explanation of alpha decay by quantum tunneling, invented the liquid drop model (the first mathematical model of the atomic nucleus), worked on radioactive decay, star formation, stellar nucleosynthesis, Big Bang nucleosynthesis (which he collectively called nucleocosmogenesis), and predicted the existence of the cosmic microwave background radiation and molecular genetics. In his middle and late career, Gamow directed much of his attention to teaching and wrote popular science, including One Two Three... Infinity and the Mr Tompkins series.
