First, the story of mathematicians.

Such as: 1, Hua et al.

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 the interview: "What is your greatest wish?"

Without thinking, he replied, "Work until the last day." On the last day of working hard for science, he really fulfilled his promise.

2. Zu Chongzhi

Zu Chongzhi and his son Zuxuan (also a famous mathematician in China) solved the calculation of the volume of a sphere with ingenious methods. One principle they adopted at that time was: "If the power supply potential is the same, the products will not be different." That is to say, two solids located between two parallel planes are cut by any plane parallel to these two planes. If the areas of two sections are always equal, then the volumes of two solids are equal. This principle is called cavalieri principle in western languages, but it was discovered by Karl Marx more than 1000 years after the ancestor. In order to commemorate the great contribution of grandfather and son in discovering this principle, everyone also called this principle "Zu shovel principle".

Second, interesting things about mathematics.

1. There's an old Indian story: the king and the chess player from China lost in chess. The chess player from China asked to put one grain of wheat in the first box, two grains in the second box and four grains in the third box, that is, to fill all the boxes according to the method of increasing compound interest. The king thought he could get rid of the chess player with a bag of wheat at most, but he found that even if he brought all the wheat produced in the world, it would not be enough to compensate.

2, rounding

Zaizai came back from school in high spirits and asked his mother, "Where's Dad?"

Mother saw Zaizai's excitement and asked strangely, "Is Dad at home? What do you want with dad? " "I asked my father for fifty cents."

"Why?" Mom asked.

"Before taking the math test, my dad told me,' If I get a score of 100, I'll get 1 yuan, and 80 will be given to 8 cents.' Today, I got 45 points in math. "Aberdeen replied.

My mother was surprised and asked, "What! Mathematics is only 45 points? "

Zaizai proudly said, "Yes, it has to be rounded off mathematically, so Dad has to pay 50 cents."

3. Law of Multiplication and Distribution

The teacher found a student's name in the exercise book: Mu (1+2+3).

The teacher asked, "Whose exercise book is this?"

A student stood up and said, "It's mine!"

Teacher: "What's your name?"

Student: "Mulinsen!"

Teacher: "Then how did you write your name like this?"

Student: "I used multiplication and division!" " "

The essence of mathematics lies in freedom. cornel

Some beautiful theorems in mathematics have such characteristics: they are easy to be summarized from facts, but the proofs are extremely profound. Gauss
