1, Veda

The Vedas (1540—— 1603) are French mathematicians. When I was young, I studied law, worked as a lawyer, later engaged in political activities, worked as a member of parliament, and deciphered enemy codes for the government during the Spanish War. David is also devoted to mathematical research. He was the first to consciously and systematically use letters to represent known numbers, unknowns and their powers, which brought great progress in algebraic theory research.

David discussed various rational transformations of equation roots and found the relationship between equation roots and fractions. David is known as the "father of algebra" in Europe. 1579, David published "Mathematical Laws Applied to Triangle", and also found that this is the first analytical expression of π.

2. Buffon

One day, French mathematician Buffon invited many friends to his home and did an experiment. Buffon spread a big piece of white paper on the table, which was covered with parallel lines with equal distance. He also took out many small needles of equal length, the length of which was half that of parallel lines. Buffon said, "Please leave these small needles on this piece of white paper!" " The guests did as he said.

Buffon's statistical result is that everyone * * * throws 22 12 times, in which the small needle intersects the parallel line on the paper 704 times, and 22 10 ≈ 704. 142。 Buffon said, "This number is an approximation of π. Every time you get an approximation of pi, the more times you throw it, the more accurate the approximation of pi is. " This is the famous Buffon Experiment.

3. Zu Chongzhi

Zu Chongzhi was a mathematician and astronomer in the Southern and Northern Dynasties. Zu Chongzhi's mathematical work Composition records many mathematical calculation methods, such as the calculation of the roots of some special quadratic equations and cubic equations.

Zu Chongzhi's grandfather and father were both officials, so it was inevitable that Zu Chongzhi was forced to study the Four Books and Five Classics when he was a child. Zu Chongzhi Jr. is not good at learning these things, and is often called a stupid pig and cow by his father because he can't recite the text.

4.gaussian

Gauss, a famous German scientist, was born in a poor family. Gauss learned to calculate by himself before he could speak. When he was three years old, he watched his father calculate his salary one night and corrected his father's calculation mistakes.

One day, Gauss's math teacher was very depressed. Say to the students, "You calculated the sum of 1 plus 2 plus 3 to 100 for me today. Whoever can't figure it out will be punished for not going home for lunch. " As a result, in less than half an hour, Xiao Gao Si picked up the slate and stepped forward. "Teacher, is this the answer?"

Without looking up, the teacher waved his thick hand and said, "Go, go back!"! Wrong. " Gauss stood still and put the slate in front of the teacher: "Teacher! I think this answer is correct. "

The math teacher wanted to shout, but he was surprised when he saw the number written on the slate: 5050. How did this 8-year-old get the answer so quickly?

Gauss explained a method he discovered, which was used by the ancient Greeks and China people to calculate the sequence1+2+3+…+n. Gauss's discovery made the teacher feel ashamed, and felt that his previous view of being arrogant and belittling poor children was wrong. He also taught seriously in the future, and often bought some math books from the city for his own study and lent them to Gauss. With his encouragement, Gauss later did some important research in mathematics.

5. Hua

Watson was born in Jiangsu. He likes math since he was a child, and he is very clever. 1930, 19-year-old Hua went to Tsinghua University to study. During his four years in Tsinghua, under the guidance of Professor Xiong Qinglai, Hua studied hard and published more than a dozen papers in succession. Later, he was sent to study in Britain and got a doctorate.

He studied number theory deeply and got the famous Fahrenheit theorem. He paid special attention to integrating theory with practice and traveled to more than 20 provinces, municipalities and autonomous regions to mobilize the masses to apply the optimization method to agricultural production.

The reporter asked him in an interview: "You are the biggest. What is the wish? " Without thinking, he replied, "Work until the last day." On the last day of working hard for science, he really fulfilled his promise.
