Chen Jingrun is a famous mathematician in China. He doesn't like going to the park and walking, but studying. When he studies, he often forgets to eat and sleep. One day, when Chen Jingrun was having lunch, he touched his head and found that his hair was too long. He should get a haircut quickly, otherwise people will think he is a big 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 got brand number 38. He thought, it's still early for me to turn around. 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 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 calling number 38?

2. Gauss:
When Gauss was at the University of G? ttingen, he was late for something once, and almost all the classes were over when he got to the classroom. Gauss walked into the classroom and found that the teacher was not there. He wrote several questions on the blackboard. Gauss thought these questions were today's homework, so he wrote them down. That night, he spent the whole night studying these math problems. Unexpectedly, these problems are extremely difficult. Gauss didn't solve a problem until dawn. The next day, he found the teacher in frustration and told him all about it.
His teacher was shocked: "These are the most famous problems in the history of mathematics, and you actually solved one in one night?" The problem solved by Gauss is the problem of drawing a regular heptagon ruler that has puzzled mathematicians for two thousand years. That year, Gauss was only 19 years old!
3. Hua:
Once, while looking at the shop, Hua was solving a math problem. A lady came and wanted to buy cotton. When she asked Hua how much it was, he was completely absorbed in the problem and didn't hear what the other party said. After calculating the answer, he casually said a number. The lady thought he was talking about the price of cotton and screamed, "Why is it so expensive?" .
At this time, Hua knew that someone had come to buy cotton. When Hua sold cotton to a lady, he found that the toilet paper he used to calculate the problem was taken away by the lady. This made Hua desperate to catch up with the young lady, and he finally caught up with her. Hua said shyly, "Auntie, please … please give me back the toilet paper."
The woman said angrily, "This is the money I paid, not you." Hua said anxiously, "How about this? I paid for it. " When Hua reached for the money, the woman seemed to be moved by the child! He not only asked for money, but also returned the toilet paper to Hua. At this time, HuaCai slightly relieved. After returning home, I began to calculate math problems again. ...
4. Lagrange:
Lagrange (1736— 18 13) is a famous French mathematician, mechanic and astronomer, a pioneer of variational method and the founder of analytical mechanics. 18th century is known as "the greatest hope in Europe and the greatest mathematician in Europe".
Lagrange was born in Turin, Italy. As the eldest son, his father wants him to study law. However, Lagrange has no interest in law and loves literature.
Until 16 years old, Lagrange was still very partial to literature and had no interest in mathematics. /kloc-when he was 0/6 years old, he accidentally read an article introducing Newton's calculus, discussing the advantages of analytical methods, which aroused his infinite admiration and admiration for Newton, so he made up his mind to become a Newton mathematician.
5. Zu Chongzhi:
Zu Chongzhi's ancestral home was in Hebei, and his grandfather and father were officials in the Southern Dynasties, so he was born in the South. At the end of the Jin Dynasty, due to years of melee in the north, a large number of people from the Central Plains moved south, which promoted the rapid development of agricultural production and social and economic aspects in the Yangtze River basin. Zu Chongzhi was born in this era. Our ancestors have been studying astronomy and calendars for generations. Under the influence of his family, Zu Chongzhi became interested in astronomy and mathematics at an early age.
In his youth, he made a thorough and detailed study of the work of Liu Xin, Zhang Heng, dorri and Liu Hui, and refuted their mistakes. Later, he continued to study and made extremely valuable contributions to science and technology. Pi, which is accurate to the sixth decimal place, is one of his most outstanding achievements. In terms of astronomical calendar, he sorted out the documents he could collect from ancient times to the present. And through personal observation and calculation, he made in-depth verification. He pointed out that there were many serious mistakes in the calendar compiled by He Chengtian (370-447 AD) at that time, so he began to compile a new calendar.
