John von Numa (1903- 1957), a Hungarian American, was born in Budapest, Hungary on February 28th, 1903. His father is a banker, his family is very rich, and he attaches great importance to children's education. Von Neumann is talented and has many interests. Reading never forgets anything. It is said that he was able to chat with his father in ancient Greek when he was six years old, and he mastered seven languages in his life. He is best at German, but when he thinks in German, he can translate it into English at the speed of reading. He can quickly repeat the contents of books and papers he has read word for word, and he can still do so a few years later. +09 1 1. Von Neumann became famous when he was studying in Lu Se Lun Middle School in Budapest, and was highly valued by his teachers. Under the individual guidance of Mr Fichte, he co-published his first mathematical paper. At this time, von Neumann was less than 18 years old. 192 1- 1923, he studied at the University of Zurich. Soon after, he got a doctorate in mathematics from Budapest University with 1926. Von Neumann was only 22 years old at this time .30438+0927. 1930 accepted the position of visiting professor at Princeton University and went to the United States. 193 1 became the first batch of tenured professors at Princeton university in the United States. At that time, he was less than 30 years old. 1933 transferred to the Institute of Advanced Studies, became one of the first six professors, and worked there all his life. Von Neumann is an honorary doctor of Princeton University, University of Pennsylvania, Harvard University, Istanbul University, University of Maryland, Columbia University and Munich Institute of Advanced Technology. He is the seat of the National Academy of Sciences, the National Academy of Natural Sciences of Peru and the National Forestry Institute of Italy/kloc-0 10000.0000000000606 President of the American Mathematical Society 195 1 to 1953.

1954 In the summer, von Neumann was diagnosed with cancer. 1957 died in Washington on February 8, at the age of 54.

Von Neumann has done pioneering work and made great contributions in many fields of mathematics. Before World War II, he mainly engaged in the research of operator theory and set theory. 1923' s paper on the over-limit ordinal number in set theory shows von Neumann's unique way and style of dealing with the problem of set theory. He axiomatized set theory, and his axiomatic system laid the foundation of axiomatic set theory. Many important concepts, basic operations and important theorems in set theory are derived by algebraic methods. Especially in a paper in 1925, von Neumann pointed out that there are undecidable propositions in any axiomatic system.

1933, von Neumann solved Hilbert's fifth problem, that is, he proved that a locally Euclidean compact group is a Lie group. 1934, he unified the compact group theory with Bohr's almost periodic function theory. He also has a deep understanding of the structure of general topological groups, and clearly points out that its algebraic structure and topological structure are consistent with real numbers. He did pioneering work in operator algebra and laid its foundation. Thus, a new branch of mathematics, operator algebra, is established. This branch is called von Neumann algebra in contemporary mathematical literature. This is a natural extension of matrix algebra in finite dimensional space. Von Neumann also founded another important branch of modern mathematics-game theory. 1948+0944 published a fundamental and important paper Game Theory and Economic Behavior. This paper includes the explanation and practice of pure mathematical form of game theory. Von Neumann has done important work in lattice theory, continuous geometry, theoretical physics, dynamics, continuum mechanics, meteorological calculation, atomic energy and economics.

Gauss [1] (Johann Carl Friedrich Gauss) (1April 30, 777-1February 23, 855) was born in Brunswick and died in G? ttingen, a famous German mathematician, physicist, astronomer and geographer. Gauss is regarded as the most important mathematician, and has the reputation of prince of mathematics. He is also known as one of the greatest mathematicians in history, along with Archimedes, Newton and Euler.

Gauss 1977 was born in a craftsman's family in Brunswick on April 30th, and 1985 died in G? ttingen on February 23rd. When I was a child, my family was poor, but I was extremely smart. Before I went to school to receive an education, I was sponsored by a noble. From 1795 to 1798, I studied at the University of G? ttingen, and 1798 transferred to Helmstadter University. The following year, he received his doctorate for proving the basic theorem of algebra. From 1807, he served as a professor at the University of G? ttingen and director of the G? ttingen Observatory until his death.

Gauss's achievements cover all fields of mathematics, and he has made pioneering contributions in number theory, non-Euclidean geometry, differential geometry, hypergeometric series, complex variable function theory, elliptic function theory and so on. He attached great importance to the application of mathematics, and emphasized the use of mathematical methods in the research of astronomy, geodesy and magnetism.

1792, 15-year-old Gauss entered Brunswick College. There, Gauss began to study advanced mathematics. The binomial theorem, quadratic reciprocity law, prime number theorem and general forms of arithmetic geometric average in number theory were discovered independently.

1795 Gauss entered the University of G? ttingen. 1796, 19-year-old gauss got a very important achievement in the history of mathematics, that is, the theory and method of drawing a regular heptagon ruler. Five years later, Gauss proved that a regular polygon with sides similar to Fermat prime number can be made with a ruler.

1On the morning of February 23rd, 855, Gauss died in his sleep.

Uncle Yan (99 1- 1055) is the same as uncle. A native of Wengang Township, Linchuan County, Fuzhou in the Northern Song Dynasty, he was a famous poet in the early Northern Song Dynasty. /kloc-at the age of 0/4, he entered the exam as a child prodigy, was given a Jinshi background, and was appointed as the provincial secretary. He moved to Taichang Temple to serve, Guanglu Temple Cheng, Shangshuhu Yuanwailang, Prince Sheren, Hanlin Bachelor, and Zi successively, and moved to Youjian Doctor as a bachelor when Injong ascended the throne. He served as an assistant minister in the Ministry of Rites, worshipped the envoys of the Tang Dynasty, participated in politics and added Zuo Cheng, a minister of history, and worshipped the bachelor of Jixian Hall in celebration. Yan Shu has successively held important positions, even promoted backward, such as Fan Zhongyan, Han Qi and Ouyang Xiu. He writes poems in the literary world, especially short stories, with more than 30 Zhu Yu's poems/kloc-0, and his style is subtle and beautiful. His representative works include Huanxisha, Butterfly Loves Flowers, Walking on the Beach, Breaking the Array, Treading on Magpies and so on. Among them, Huanxisha is a famous sentence that has been passed down for generations. He is also good at poetry and prose. There are 240 volumes of his original poems, and there are not many existing ones. Most of them are good at elegance and splendor.

Li Zhengdao: Li Zhengdao (1926165438+1October 25th-), a Chinese American physicist, Han nationality, was born in Shanghai, China. 1957, 3 1 year-old, and Yang Zhenning won the Nobel Prize in Physics for discovering that parity is not conserved in weak interaction. Their findings were confirmed by Wu Jianxiong's experiments. Li Zhengdao and Yang Zhenning were the first China people to win the Nobel Prize.
