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 just calculated for him was taken away by a lady. This made Hua eager to catch up with the young lady, and he finally caught up. Hua said shyly, "Auntie, please … please give me back the toilet paper." The woman said angrily, "I paid for this."
Hua was in a hurry and said, "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. ...
2.8-year-old Gauss discovered the mathematical theorem.
Gauss was born in a poor family. One night when he was three years old, he watched his father calculate his salary 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 will also teach seriously in the future.
3. Galileo questioned authority
/kloc-At the age of 0/7, Galileo was admitted to the University of Pisa as a medical major. Once in class, Professor Biro gave a lecture on embryology. He said: "Whether a mother gives birth to a boy or a girl is determined by her father's strength. When the father is strong, the mother gives birth to a boy; If the father is weak, the mother will have a daughter. " As soon as Professor Biro's voice dropped, Galileo raised his hand and said, "Teacher, I have a question. My neighbor, the man is very strong, but his wife has given birth to five daughters in a row. This is just the opposite of what the teacher said. How to explain this? "
"I said it according to Aristotle, a famous ancient Greek scholar, and it can't be wrong!" Professor Biro tried to subdue him. Galileo went on to say, "Is it necessary for Aristotle to insist that what he said is true? Science must conform to the facts, otherwise it is not real science. " Professor Biro was stumped by this question and could not step down. Later Galileo was criticized by the school, but his spirit of persistence, curiosity and pursuit of truth has not changed at all. Because of this, he finally became a generation of science masters.
4. Chen Jingrun conquered Goldbach's conjecture.
1937, diligent Chen Jingrun was admitted to Huaying College in Fuzhou. At this time, during the period of War of Resistance against Japanese Aggression, Professor Shen Yuan, director of the Department of Aeronautical Engineering in Tsinghua University, returned to Fujian to attend the funeral, unwilling to stay in his hometown because of the war. Several universities got the news and wanted to invite Professor Shen to give lectures. He declined the invitation. As he is an alumnus of Huaying, he came to this middle school to teach mathematics to his classmates in order to report to his alma mater.
One day, Teacher Shen Yuan told us a story in math class: "A Frenchman discovered an interesting phenomenon 200 years ago: 6=3+3, 8=5+3, 10=5+5, 12=5+7, 28= 5+23. Every even number greater than 4 can be expressed as the sum of two odd numbers. Because this conclusion has not been proved, it is still a guess. Euler said: Although I can't prove it, I am sure this conclusion is correct. It is like a beautiful light ring, shining with dazzling brilliance in front of us not far away. ..... "Chen Jingrun stare eyes, absorbed.
5. The encyclopedic "All-rounder" Newton
From the age of 12 to the age of 17, Newton studied in Kings Royal Middle School, and his signature can be seen on the window sill of the school library. He dropped out of school. Fortunately, Henry Stokes, the headmaster of King's Royal Middle School, persuaded Newton's mother, and Newton was sent back to school to finish his studies. He finished middle school at the age of 18 and got a perfect graduation report.
1661June 3rd, entered Trinity College, Cambridge University. At that time, the teaching of the college was based on Aristotle's theory, but Newton preferred to read some more advanced ideas of modern philosophers such as Descartes and astronomers such as Galileo, Copernicus and Kepler. 1665, he discovered the generalized binomial theorem and began to develop a new set of mathematical theories, which is the world-famous calculus.
