1, Gauss (1777-1855) is a German mathematician, physicist and astronomer. Gauss showed extraordinary mathematical genius in his childhood. At the age of three, he studied arithmetic, and at the age of eight, he discovered the summation formula of arithmetic sequence, which won the admiration of teachers and classmates. In his sophomore year, he got the regular drawing of regular heptagon. The condition that a regular polygon can be drawn with a ruler is given. The unsolved problems for two thousand years have been solved. 1799 received his doctorate with four beautiful proofs of the basic theorem of algebra. Gauss's achievements in mathematics are all over various fields, and his contributions in many aspects of mathematics are of epoch-making significance. Moreover, in astronomy, geodesy and magnetism have made outstanding contributions. Arithmetic Research, published in 180 1, is one of the few classic works in the history of mathematics, which opened up a new era of number theory research. Non-Euclidean geometry is another important discovery of Gauss, and his legacy shows that he is one of the founders of non-Euclidean geometry. Gauss devoted himself to astronomical research for about 20 years. One of the masterpieces in this field is the Theory of Celestial Motion published by 1809. Gauss also made outstanding contributions to physics. Maxwell said that Gauss's magnetic research changed the whole science. Gauss also trained many outstanding mathematicians in his life.

1933 65438+ 10, Hitler issued the first decree as soon as he came to power, comparing Jews to "demons" and clamoring to crush "the rights of demons". Soon, the University of G? ttingen was ordered to dismiss all people of pure Jewish descent who were engaged in education. Among the scholars who were expelled, there was a woman named Amy? Nord (A.E. Noether1882-1935), a professor in this university, is 5l years old. The lecture she gave was forced to stop, and even her meager salary was cancelled. This woman who has achieved academic success is calm in the face of difficulties because she has spent her life in adversity. Nord grew up to be a Jewish professor of mathematics. I like math since I was a child. 1903, Nord, 2 1 year-old, was admitted to the University of G? ttingen, where he listened to lectures by Klein, Hilbert, Minkowski and others, and formed an indissoluble bond with mathematics. She published several high-quality papers when she was a student. At the age of 25, she became one of the few female doctors in mathematics in the world. Nord has made outstanding contributions to the study of differential inequalities, rings and ideal subgroups. But because of the low status of women at that time, she was not even a lecturer. With the strong support of the great mathematician Hilbert, Nord became the first female lecturer at the University of G? ttingen from Hilbert's "private lecturer". Next, due to her outstanding scientific research achievements and Hilbert's recommendation, she won.

Nord loves mathematics education and is good at inspiring students to think. She has never been married, but she has many children. She keeps close contact with students and is amiable. People affectionately call the students around her "Nord's children". China mathematician Ceng Jiong is one of Nord's "children". Under Hitler's arrogance, Nord was forced to leave the University of G? ttingen and go to work in the United States. In America, she is also respected by students. And her "children". 1934 In September, the United States established a postdoctoral scholarship named after Nord. Unfortunately, Nord died of surgery less than two years after working in the United States at the age of 53. Her death made many math colleagues feel infinite sorrow. Einstein delivered a eulogy at the The New York Times, saying: "According to the judgment of authoritative mathematicians, Ms. Nord is the most important creative mathematician since women received higher education.

Ju Lushi, born in 624 BC, was the first famous mathematician in ancient Greece. He used to be a shrewd businessman. After he accumulated considerable wealth by selling olive oil, Cyrus devoted himself to scientific research and travel. He is diligent and studious, at the same time, he is not superstitious about the ancients, and he is brave in exploration, creation and positive thinking. His hometown is not too far from Egypt, so he often travels to Egypt. There, Ju Lushi learned about the rich mathematical knowledge accumulated by ancient Egyptians for thousands of years. When he traveled in Egypt, he calculated the height of the pyramids in a clever way, which made the ancient Egyptian king Amerasis admire him very much.
