On this day, 57 years ago, August 20, 1968 (July 27, 1968, the Russian-American astronomer and physicist Gamow passed away. George Gamow (March 4, 1904-August 20, 1968) was a Russian-American physicist, astronomer, science writer, and founder of the Hot Big Bang cosmological model. Gamow was born in Odessa, Ukraine in 1904. His father was a teacher. Gamow experienced war and revolutionary turmoil in his youth. He entered the University of New Russia in 1922 and soon transferred to Leningrad University to study optics. He studied Friedman's universe model under the famous cosmologist Alexander Friedman. Received his doctorate in 1928. From 1928 to 1932, he studied under the famous physicists Bohr and Rutherford at the University of Göttingen in Germany, the Institute of Theoretical Physics at the University of Copenhagen in Denmark, and the Cavendish Laboratory at the University of Cambridge in the United Kingdom. While at the University of Göttingen, Gamow successfully applied quantum theory to the study of atomic nuclei, explaining alpha decay. In 1931, Gamow was recalled to the Soviet Union, appointed chief researcher of the Leningrad Academy of Sciences, and served as professor of physics at Leningrad University. Under the Stalin system at that time, Gamow felt that his imaginative nature was suppressed and he was very unhappy. While attending a conference in Brussels, Belgium, in 1933, Gamow seized the opportunity to leave the Soviet Union. After leaving the Soviet Union, Gamow conducted research at the Curie Institute in Paris, France. In 1934, he moved to the United States and served as a lecturer at the University of Michigan. In the fall of the same year, he was hired as a professor at the University of Washington in Colombia. While working at the University of Washington, Gamow was mainly engaged in cosmology and astrophysics, developed the Big Bang universe model, and studied the origin of chemical elements in the initial stage of the universe. This period was the peak of his academic career and achieved a series of important research results. Gamow served as a professor at the University of California, Berkeley in 1954, and at the University of Colorado in 1956, turning his research center to molecular biology. During this period, Gamow proposed the "genetic code" of DNA molecules. The modern Big Bang theory was first proposed in 1932 by the Belgian priest Lemait. In the 1940s, Gamow, together with two of his students, Ralph Alfie and Robert Herman, introduced the theory of relativity to cosmology and proposed a hot Big Bang cosmological model. The hot Big Bang cosmological model believes that the universe originally began with raw matter with high temperature and density, with temperatures exceeding several billion degrees. As the universe expanded, the temperature gradually dropped, forming today's galaxies and other celestial bodies. They also predicted the existence of cosmic microwave background radiation. In 1964, American radio engineers Arnold Penzias and Robert Wilson accidentally discovered the cosmic microwave background radiation, confirming their prediction. In the 1940s, Gamow assigned Alfie to study the theory of element synthesis during the Big Bang. In Alfie's doctoral thesis submitted in 1948, Gamow persuaded Hans Beit to sign his name on the paper and his own name at the end, so that the homophonic sounds of the three names formed the first three Greek letters ¦Á, ¦Â, and ¦Ã. So this paper marking the Big Bang model of the universe was published on April 1, 1948, April 1, 1948, in the name of Alpher, Bett, and Gamow. It is called the ¦Á¦Â¦Ã theory. Gamow is also an excellent science writer and is regarded as a master of the generation in the science popularization community. Among the 25 books officially published in his life, 18 are popular science works, the most representative of which is "Adventures in the Physical World". In this work, Gamow successfully created the image of Mr. Tompkins, a bank clerk who only understood numbers but not science. Through his wonderful experience of sleepwalking in the physical fantasy, he used witty, humorous and vivid language to introduce the important concepts of physics to readers and achieved great success. In 1956, Gamow won the Kalinga Science Prize awarded by UNESCO. Comment: A very great scientist who has received high honors in many aspects.
