The story of mathematician Hua Luogeng.
Hua Luogeng's family was poor when he was a child, and in order to make a living, he used to work as a clerk in a shop selling cotton. Once, a woman went to buy cotton, Hua Luogeng was calculating a math problem, and a woman said how much cotton would cost? However, the diligent Hua Luogeng didn't hear it, so he answered the answer to the calculation, and the woman screamed:
Why is it so expensive? At this time, Hua Luogeng knew that someone had come to buy cotton, so he said**, and the woman bought a bag of cotton and left. Hua Luogeng was about to sit down and continue to count, only to find out:
The straw paper that had just been counted was taken away by the woman. This made Hua Luogeng anxious, so he desperately chased after him, and finally caught up, Hua Luogeng said embarrassedly: "Auntie, please ......."Please give me back the straw paper", said the woman angrily
I paid for it, not you." Hua Luogeng was in a hurry, so he said: "Otherwise!
I paid for it." When Hua Luogeng reached out to take out the money, the woman seemed to be moved by this child! Not only did he not ask for money, but he also returned the straw paper to Hua Luogeng.
At this time, Hua Luogeng was slightly relieved, and after returning home, he calculated ......

Archimedes. King Heelous of Syracuse asked a goldsmith to make a crown of pure gold, and because he suspected that it was mixed with silver, he asked Archimedes to identify it. When he entered the tub to bathe, the water overflowed into the tub, and he realized that objects of different materials, although they weigh the same, must not drain the same amount of water because of their different volumes.
Based on this reasoning, it is possible to determine whether the crown is adulterated or not.
Ancient Greece is the homeland of mathematics The ancient Greeks spent a lot of effort and even their lives on the progress of mathematics and made outstanding contributions This ancient civilization nurtured many mathematicians, such as Thales, Pythagoras, Euclid, Apollonius, Archimedes, Ptolemy, Helen, Diophantus, etc. Hypatia, the first female mathematician in history, was also born here.
Hypatia (c. 370-415). Born in Egypt. He was a famous mathematician in ancient Greece.
She is known as the world's first female mathematician. This intelligent woman ranked among the finest scholars of the ancient world with her talent and contributions. And her tragic death is truly a tragedy for the ages.
Savage and cruel religious fanatics have poisoned her.
Zu Chongzhi (429-500 AD) was a native of Laiyuan County, Hebei Province during the Northern and Southern Dynasties of China He read many books on astronomy and mathematics since he was a child, and he was diligent and studious, and practiced hard, which finally made him an outstanding mathematician and astronomer in ancient China
Zu Chongzhi's outstanding achievement in mathematics is about the calculation of pi Before the Qin and Han dynasties, people to"Trail three times a week"As pi, this is"Ancient rate"Later, it was found that the error of the paleorate was too large, and the pi should be"The circle diameter is more than three days", but how much is left, opinions differ Until the Three Kingdoms period, Liu Hui proposed a scientific method for calculating pi"Circumcision", use the circumference of the circle with the circumference of the circle with the circumference of the regular polygon to approximate the circumference of the circle Liu Hui calculates that the circle is connected with 96 sides, and obtains =, and points out that the more sides of the inscribed regular polygon, the more accurate the value obtained Zu Chongzhi on the basis of the achievements of his predecessors, after hard study and repeated calculations, found between and
Su Buqing was born in September 1902 in Zhejiang Province. When I was in my third year of junior high school, a math teacher came. He said:
In today's world, the world's great powers want to carve up China. The danger of China's demise is imminent. In order to save the world, science must be revitalized.
Mathematics is the pioneer of science, and in order to develop science, it is necessary to learn mathematics well. At the age of 17, Su Buqing went to Japan to study. When he went to become an associate professor at a university in Japan, Su Buqing decided to return to China.
In the face of the predicament, he was: "What is the benefit of enduring hardships, I am willing, because I have chosen a correct path, which is a patriotic and bright road!" ”

Gauss Jr. It took one night to make a regular 17-sided shape that had not been solved for more than 2,000 years. When the teacher asked Gauss how he did it, he said, "If I had known that this was a puzzle that had not been solved for more than 2,000 years, I would not have had the confidence to do it." ”

Hello dear! Here is a short description of the stories of the five mathematicians:1
Pascal: Mathematician of the first country of French trousers, 17th century period. He once studied probability in a casino, discovered the famous Pascal triangle, and is known as the founder of combinatorics.
2.Albert Einstein: German-American mathematician and physicist.
His theories of relativity have had a profound impact on modern physics. He also proposed the famous e=mc formula and is known as the father of modern physics. 3.
Dirichlet: German mathematician and an important figure in the field of mathematical analysis in the 19th century. He proposed the Dirichlet series, which is an important tool in number theory, and also discovered some important search for functional properties.
4.Hilbert: German mathematician, one of the most prominent mathematicians of the late 19th and early 20th centuries.
He is one of the founders of modern mathematics and has made significant contributions to the development of mathematics. 5.Morbius:
German mathematician, 19th century period. He made important contributions to the development of topology. Both the Möbius Ring and the Möbius Belt are named after him.
He also founded the German Mathematical Society, which includes topology. Hope it helps!

Summary. 1.Dirichlet's Dream:
While doing the Langsky series, Dirichlet dreamed that a mysterious figure told him how to calculate the series, so he proposed the Dirichlet criterion, which opened up a new method of calculating the series for future generations. 2.Einstein and that equation:
Einstein leaned against the fire and thought endlessly, and finally came up with his tetrastichon formula. The solution of this formula is an important basic theory of modern physics. 3.
Stirling and Factorial: On a date together, Sterling talks to his girlfriend about factorial calculations, and his girlfriend answers the answer, which shocks Sterling, so he invents the Stirling formula to solve the factorial calculation problem. 4.
Leibniz and Calculus: Leibniz eventually invented calculus through correspondence with Galileo and Newton, combined with his own independent work. 5.
Cantor and Set Theory: Cantor was the creator of set theory, he proposed the concepts of infinity and continuity, and proved that at least two classes of infinity have different potentials in quantity. His theory has been hailed as a milestone in the history of mathematics.
Hello dear friends, it is my pleasure to answer your <>
The stories of the 5 mathematicians are as short as follows:
1.Dirichlet's Dream: While doing the Langsky series, Dirichlet dreamed that a mysterious figure told him how to calculate the series, so he proposed the Dirichlet criterion, which opened up a new method for future generations to calculate the series.
2.Einstein and the equation: Einstein leaned over the fire and thought about it, and finally came up with his tetrastichon formula.
The solution of this formula is an important basic theory of modern physics. 3.Stirling vs. Factorial:
On a date together, Sterling talked to his girlfriend about factorial calculations, and his girlfriend answered the answer, which shocked Sterling, so he invented Stirling's formula to solve the problem of factorial calculations. 4.Leibniz and Calculus:
Leibniz, through correspondence with Galileo and Newton, combined with his own independent work, eventually invented calculus. 5.Cantor and Set Theory:
Cantor was the creator of set theory, he proposed the concepts of infinity and continuity, and proved that at least two classes of infinity have different potentials in quantity. His theory has been hailed as a milestone in the history of mathematics.

On Sunday, I went to my aunt's stationery store to buy school supplies, and my aunt had something to do and asked me to look at the store for a while. After a while, an uncle came, and he said that he would test me so that he could tell me what to buy. He said:
Zhang Dan bought a pencil and an exercise book, which cost a total of yuan. An exercise book costs twice as much as a pencil. How much do pencils and exercise books cost?
I want to shake the chain and think about it: the exercise book and the pencil are three times as much, as long as you use it, you can find the pencil's **, and the exercise book's ** can also be found. I said that the unit price of the pencil is yuan, and the unit price of the exercise book is yuan, and my uncle praised me for being smart:
It's nice to be able to analyze the topic carefully! "You have each yuan of exercise books here, each yuan of text, I want to buy 10 books, give you yuan, don't look for it, how many exercise books should you give me, how many books as texts?" "I thought about it and said:
First of all, assuming that 10 books are all texts, 10 yuan is needed, and the actual yuan is paid, which is less than the hypothetical payment, and the actual texts are more diverse than the exercise books, then we can find that the exercise books are the books, and the texts are 10-3=7 books. Later, my uncle bought a few stationery, and I was still immersed in joy when I checked out, but I miscalculated the money, I didn't find out, but Uncle Duan Zisun said to me: "You, you will get carried away when you praise you."
I misread the decimal point of the money I should have paid, and as a result, I paid less. "I'm sorry, the decimal point has moved one place to the left, 10 times smaller than the original **, a difference of 9 times, as long as the yuan, because it was reduced by 10 times just now, so I want the yuan. "Auntie bought a few more stationery and left.
Today, my harvest is really great, mathematics in life is indeed everywhere, mathematics is really broad and profound, I want to work harder, and strive to reach a higher level!
The fact that Gauss was able to correct his father's debt accounts at the age of 3 has become an anecdote that has survived to this day. He once said that he learned to calculate on the Mai Xian Ong pile. Being able to make complex calculations in his head was a gift from God that he had given him a lifetime. >>>More
