One day, Chen Jingrun touched his head during lunch. Oh, his hair is too long. He should get a haircut quickly, or people will think he is a girl when they see him. So he left work and ran to the barber shop.
There are so many people in the barber shop that everyone cuts their hair next to each other. Chen Jingrun's brand is the small brand number 38. He thought it was too early for me to turn now. Time is so precious that I can't waste it. He hurried out of the barber shop, found a quiet place to sit down, then took out a small notebook from his pocket and recited new words in a foreign language. He recited it for a while and suddenly remembered that when he was reading a foreign language in the morning, there was one place he didn't understand. You must understand what you don't understand. This is Chen Jingrun's temper. He looked at his watch. It's only half past twelve. He thought: check in the library first, and then come back for a haircut. He stood up and left. Who knows, not long after he left, it was his turn to get a haircut. The barber's uncle shouted, "Number 38! Who is number thirty-eight? Come and get a haircut! " Think about it. Chen Jingrun is reading in the library. Can he hear the barber's uncle calling number 38?
After a long time, Chen Jingrun found something he didn't understand in the library, and then went to the barber shop happily. But he passed by the foreign language reading room, and there were all kinds of new books, which were really nice. He ran in and read another book. It was not until the sun went down that he remembered to cut his hair. As soon as he touched his pocket, the little sign No.38 was still lying well. But what's the use of his coming to the barber shop? This number is outdated.
2. Archimedes
King Shiloh of Syracuse asked the goldsmith to make a crown out of pure gold. Because it is suspected that there is silver mixed in it, Archimedes is invited to identify it. When he entered the bathtub to take a bath, the water overflowed outside the bathtub, so he realized that although the weight of objects made of different materials was the same, the discharged water would be different because of their different volumes. According to this truth, it can be judged whether the crown is adulterated.
3. Hua (1910.12-1985.6.12. ), a world-famous mathematician, is China's analytic number theory, matrix geometry, canonical group and self-safe function theory. The international mathematical research achievements named after Fahrenheit include Fahrenheit theorem, Huai-Hua inequality, Fahrenheit inequality, Prawell-Gardiner theorem, Fahrenheit operator, Hua-Wang method and so on.
4. 1966 Chen Jingrun, who lives in a 6-square-meter cabin, borrowed a dim kerosene lamp, leaned against the bed board, used a pen and consumed several sacks of draft paper. He actually conquered (1+2) in the world-famous mathematical puzzle "Goldbach conjecture", creating a distance from taking off the crown jewel of number theory (1+). He proved that "every big even number is the sum of the products of a prime number and no more than two prime numbers", which made him a world leader in Goldbach's conjecture research. This result is called "Chen Theorem" internationally and is widely quoted. This work also enabled him, Wang Yuan and Pan Chengdong to win the first prize of China Natural Science Award with 1978 * *. His achievements in studying Goldbach conjecture and other number theory problems are still far ahead in the world. A world-class master of mathematics and American scholar A Will (A? Weil) once praised him like this: "Every job in Chen Jingrun is like walking on the top of the Himalayas.
