1. Hua Luogeng is addicted to arithmetic

One time, Hua Luogeng was calculating a math problem when he was looking at the store. A lady came and wanted to buy cotton. When she asked Hua Luogeng how much it cost, he He was completely immersed in doing the questions and did not hear what the other party said. When he finished calculating the answer, he casually mentioned a number. The lady thought he was talking about the price of cotton and screamed: "Why is it so expensive?" At this time, Hua Luogeng Only then did he know that someone came to buy cotton. When Hua Luogeng sold the cotton to the lady, he discovered that the papyrus for his calculations had been taken away by the woman. This made Hua Luogeng so anxious that he chased the lady desperately, but was eventually taken away. He caught up with him, and Hua Luogeng said embarrassedly: "Auntie, please...please return the papyrus to me." The woman said angrily: "I bought this with money, not as a gift from you."

Hua Luogeng was very anxious, so he said: "How about this! I will spend money to buy it." When Hua Luogeng reached out to take out the money, the woman seemed to be moved by the child! Not only did he not ask for money, he also returned the papyrus to Hua Luogeng. At this time, Hua Luogeng breathed a sigh of relief. After returning home, he started to calculate math problems again...

Gauss discovered the mathematical theorem at the age of 2.8

Gauss was born in a poor family. One night when he was three years old, he I watched my father correct his calculation errors when he was calculating wages. One day Gauss's math teacher was having a bad day. He said to his classmates: "You can calculate the sum from 1 plus 2 plus 3 to 100 for me today. Whoever can't calculate will be punished and cannot go home for lunch." In less than half an hour, little Gauss picked up his The stone slab stepped forward. "Teacher, is this the answer?"

The teacher didn't even raise his head, waved his fat hand and said, "Go, do the math again when you get back! Wrong." Gauss, however, stood still and put his The slate was stretched out in front of the teacher: "Teacher! I think this answer is correct." The math teacher wanted to roar, but when he saw the number written on the slate: 5050, he was surprised, how could this 8-year-old kid be so fast? Did you get the answer?

Gauss explained a method he discovered, which was the method used by the ancient Greeks and Chinese to calculate the series 1+2+3+…+n. Gauss's discovery made the teacher feel ashamed and felt that his previous views of being arrogant and contemptuous of children from poor families were wrong. He also started teaching seriously later on.

3. Galileo questioned authority

When Galileo was 17 years old, he was admitted to the medical major of the University of Pisa. Once in class, Professor Biro taught embryology. He said: "Whether a mother gives birth to a boy or a girl is determined by the strength of the father. If the father is strong, the mother will give birth to a boy; if the father is weak, the mother will give birth to a girl." As soon as Professor Biro finished speaking, Galileo He raised his hand and said, "Teacher, I have a question. My neighbor is a very strong man, but his wife gave birth to five daughters in a row. This is exactly the opposite of what the teacher said. How to explain this?"

"I am basing this statement on the views of the famous ancient Greek scholar Aristotle, and it is not wrong!" Professor Biro wanted to convince him. Galileo continued: "Does Aristotle insist that what he said is correct even though it is not consistent with the facts? Science must be consistent with the facts, otherwise it is not real science." Professor Biro was stunned by the question and continued. Can't get on stage. Later, Galileo was indeed criticized by the school, but his spirit of perseverance, inquisitiveness, and pursuit of truth remained unchanged at all. Because of this, he eventually became a scientific giant.

4. Chen Jingrun conquered Goldbach’s conjecture

In 1937, the diligent Chen Jingrun was admitted to Fuzhou Yinghua Academy. At this time, during the Anti-Japanese War, the director of the Aeronautical Engineering Department of Tsinghua University stayed. Professor Shen Yuan, a British doctor, returned to Fujian for the funeral and did not want to be stranded in his hometown due to the war. After hearing the news, several universities wanted to invite Professor Shen to give lectures, but he declined the invitation. Since he is an alumnus of Yinghua, in order to report to his alma mater, he came to this middle school to teach mathematics to his classmates.

One day, Teacher Shen Yuan told everyone a story in mathematics class: "Two hundred years ago, a Frenchman discovered an interesting phenomenon: 6=3+3, 8=5+3, 10=5+5, 12=5+7, 28=5+23, 100=11+89. Every even number greater than 4 can be expressed as the sum of two odd numbers, so it is still one. guess.

The great mathematician Euler said: Although I cannot prove it, I am convinced that this conclusion is correct. It is like a beautiful halo, shining with dazzling brilliance not far in front of us. ..." Chen Jingrun stared, listening intently.

5. Encyclopedia-style "all-rounder" Newton

From about 12 to 17 years old, Newton was in the Royal King of Kings He dropped out of school, and his signature can still be seen on the window sill of the school's library. Fortunately, Henry Stokes, the principal of Kinges Royal School, persuaded Newton's mother and Newton was sent back. He went to school to complete his studies. He completed high school at the age of 18 and received a perfect graduation report. On June 3, 1661, he entered the third year of Cambridge University. 1 Academy. At that time, the teaching of the Academy was based on the teachings of Aristotle, but Newton preferred to read the more advanced ideas of some modern philosophers such as Descartes and astronomers such as Galileo, Copernicus, and Kepler. In 1665, he discovered the general binomial theorem and began to develop a new mathematical theory that later became known as calculus.
