1. Archimedes: King Heelous of Syracuse commissioned a goldsmith to build a crown of pure gold, suspected of being mixed with silver, and asked Archimedes to identify it. Although the weight is the same, the water discharged is not equal due to the difference in volume. According to this reasoning, it can be judged whether the crown is adulterated or not.
2, Hua Luogeng: When he was a child, Hua Luogeng was poor and dropped out of school before graduating from junior high school. While helping his father's shop, he still didn't forget that he didn't have time to study, he developed the habit of getting up early, being good at using fragmentary time, and being good at mental arithmetic.
There are no books, no paper and no pen, and he has developed the habit of being diligent in his hands and diligent in independent thinking.
3. Gauss: When the mathematician Gauss was in high school, the teacher would give him one or two difficult problems for him to practice, but he could basically solve them quickly, and he gave a problem a day, and he took one night to make it, and then he came to school and asked the teacher, it was a mathematical problem in the world, which has plagued mathematicians for many years.

Chen Jingrun doesn't like to play in the park, he doesn't like to walk on the road, he loves to study. When I study, I often forget to eat and sleep.
One day, when Chen Jingrun was eating lunch, he touched his head, oops, his hair is too long, he should go and get a haircut, otherwise, people will see it and think he is a girl. So, he put down his job and went to the barbershop.
It's my turn to be early. Time is too precious for me to waste. He hurried out of the barbershop, found a quiet place to sit down, then took out a small notebook from his pocket and memorized foreign words.
He memorized it for a while, and suddenly remembered that when he was reading a foreign language in the morning, there was something he didn't understand. If you don't understand something, you must understand it, this is Chen Jingrun's temper. He looked at his watch, and it was only half past twelve.
He thought: go to the library first to check it out, and then come back before it is too late to get a haircut, get up and leave. Who knows, he won't be gone long before it will be his turn to get a haircut.
Uncle barber shouted: "Thirty-eight! Who is the number thirty-eight?
Come and get a haircut! "Think about it, Chen Jingrun is reading a book in the library, can he hear the barber's uncle shouting the thirty-eighth?
After a long time, Chen Jingrun was in the library, and he understood what he didn't understand, and then happily walked to the barbershop. But when he passed by the foreign language reading room, there were all kinds of new books, which were very good. He ran in again and read the book, and when he saw the sun go down, he remembered about the haircut.
As soon as he touched his pocket, the small number 38 was still lying well. But what's the use of him coming to the barbershop, this number has long been outdated.

When Gauss was in elementary school, once after the teacher taught addition, because the teacher wanted to rest, he came up with a problem for the students to calculate, the topic was:
The teacher was thinking to herself, now the children must be counted as the end of class! I was about to excuse myself when I was about to excuse myself to go out, but I was stopped by Gauss!! It turns out that Gauss has already calculated, do you know how he calculated, kid?
There are 100 100 added up, but the equation is repeated twice, so dividing 10100 by 2 gives the answer equal to <5050>
Since then, Gauss's learning process in primary school has already surpassed other students, which has laid the foundation for his future mathematics and made him a math genius!

Once, a woman went to buy cotton, Hua Luogeng was calculating a math problem, and the woman said how much cotton she wanted?

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 counting, only to find that the straw paper had been taken away by the woman. So it chased desperately, and a yellow bag master saw the mathematician Professor Hua Luogeng, so he let him take the car, and finally caught up, Hua Luogeng said embarrassedly:
Auntie, please return the straw paper to me" The woman said angrily: "I bought it with money, not from you" Hua Luogeng was anxious, so he said: "Otherwise!
