Leonhard Euler was a Swiss physicist, mathematician, logician, geographer, astronomer, and engineer. He is credited with making influential and important mathematical discoveries, such as graph theory and infinitesimal calculus. Widely regarded as one of the greatest and most prolific mathematicians of all time, Leonhard Euler also made pioneering contributions to analytic number theory and topology.
Nobel Prize-winning Russian physicist Lev Landau is remembered for his pathbreaking research in quantum mechanics. A math prodigy, he had learned calculus at 13. He failed to receive his Nobel in person due to a near-fatal car crash which caused him injuries that eventually caused his death 6 years later.
Andrei Sakharov was a Russian dissident and nuclear physicist best remembered for designing RDS-37, Soviet Union's first two-stage hydrogen bomb. Also an activist for peace and human rights, Andrei Sakharov was honored with the Nobel Peace Prize in 1975. The Sakharov Prize for Freedom of Thought, which is awarded by the European Parliament, is named in his honor.
Born to school teacher parents, Ukrainian-American physicist George Gamow grew up to be a pioneer of the big-bang theory. His other contributions include the liquid-drop model of atomic nuclei and his research on DNA. Apart from various science textbooks, he also wrote the popular Mr. Tompkins series of physics books.
Nobel Prize-winning Soviet physicist Pyotr Kapitsa revolutionized science with his invention of new machines for liquefaction of gases. He is also remembered for discovering that liquid helium is superfluid. He had also served in World War I and had lost his father, wife, and children in the 1918-1919 flu epidemic.
12 Igor Tamm
Igor Tamm was a Soviet physicist whose contribution to the discovery of Cherenkov radiation earned him the 1958 Nobel Prize in Physics, which he shared with Ilya Mikhailovich Frank and Pavel Alekseyevich Cherenkov. In the 1940s and '50s, Igor Tamm played an important role in the Soviet atomic bomb project, which was authorized by Joseph Stalin.
Pavel Cherenkov was a Soviet physicist whose discovery of Cherenkov radiation in 1934 earned him the prestigious Nobel Prize in physics in 1958. He also played an important role in the investigation of photo-meson reactions and photo-nuclear and in the construction and development of electron accelerators. Over the course of his career, Cherenkov won several awards, including two Stalin Prizes.
