Hua especially likes thinking. He often shows great interest in something that others think is normal and asks some seemingly strange questions.

Once, he went to the suburbs to play with others and saw a stone man and a horse beside an abandoned grave. He asked his older companion, "How heavy are these stone men and horses?" The companion replied, "How do you know?" Unwilling, Hua thought for a moment and said, "There will always be a way to know."

2.pythagoras

Legend has it that he is a very good teacher. He thinks everyone should know some geometry knowledge. Once he saw a hard-working poor man trying to teach him geometry, so he suggested to him: If this man can learn a theorem, give him a coin.

The man studied geometry with him for money, but after a while, the student became very interested in geometry. On the contrary, he asked Pythagoras to teach faster and suggested that if the teacher taught one more theorem, he would give a coin. It was not long before Pythagoras recovered all the money he had given to the students before.

3. Euler

Euler, a Swiss mathematician, received a good theological education in his early years and served in the Russian court after becoming a mathematician. Once, the Queen of Russia invited the French philosopher Diderot to visit her court. Diderot tried to prove himself worthy of being invited by converting courtiers to atheism. Tired, the queen ordered Euler to shut the philosopher up.

So Diderot was told that a learned mathematician had proved the existence of God by algebra, and if he wanted to listen, the mathematician would give this proof in front of all courtiers. Diderot accepted the challenge happily. The next day, in court, Euler found Diderot and said solemnly in a very positive tone: "Sir, therefore God exists. Please answer! " For Diderot, this sounds reasonable. He was confused and didn't know what to say.

The people around him laughed loudly, which made the poor man feel ashamed. He asked the queen to allow him to return to France immediately, and the queen agreed very calmly. In this way, a great mathematician "defeated" a great philosopher by cheating.

4.gaussian

When Gauss went to school at the age of 7, the teacher assigned a question. 1+2+3 ........................................................................................................................................... Gauss quickly worked out the answer. At first, Gauss's teacher Butner didn't believe that Gauss had worked out the correct answer: "You must have miscalculated. Go back and do it again. " Gauss is determined, and the answer is 5050.

The calculation method of Gaussian is as follows:1+100 =1,2+99 =10/kloc-0+51=/kloc-0. There are 50 groups of such numbers from 1 to 100, so 50X 10 1=5050. Butner looked at him with new eyes.

5. Archimedes

The king made a golden crown. He suspected that the craftsman had stolen some gold with silver, so he asked Archimedes to identify whether it was made of pure gold and not to damage the crown. Archimedes held the crown in his hand and pondered all day. Archimedes took a bath. When he immersed himself in the bathtub, some water overflowed from the side of the bathtub. Archimedes saw this phenomenon and crackled in his mind. "I found it!" " .

Archimedes put an equal weight gold nugget and a silver nugget into a container filled with water, and found that the silver nugget discharged much more water. So Archimedes took a gold nugget with the same weight as the crown and put it in a container filled with water to measure the displacement; Then put the crown in a container filled with water to see if the amount of water discharged is the same, and the problem will be solved.

With further research, Archimedes principle, the most important cornerstone of fluid mechanics, was born.
