At the age of seven, little Gauss went to primary school. The teacher's name is Butner, and he is a famous local mathematician. This young teacher from the city always thinks that children in the countryside are idiots and their talents can't be displayed. In a math class in grade three, Butner lost his temper with the children again, and then wrote a long list of formulas on the blackboard: 81297+81495+81693+…+100701+69.

"wow! How many figures are there in total? How to calculate? " The more nervous the students are, the more they can't figure out how to calculate.

Butner is very proud. He knew that the last number was 100, which was larger than the previous number 198. Even if these naughty students do their calculations obediently all morning, they won't work out the results.

Unexpectedly, in a short time, Gao Xiaosi came over with a small slate with the answer written on it and said, "Teacher, I have finished the calculation." Without looking up, Butner said angrily, "Go, don't be ridiculous. Anyone who wants to scribble numbers must be careful! " Say that finish, waved a hammer fist.

But little gauss insisted on not leaving and said, "teacher, I'm not kidding." And gently put the small slate on the platform. Butner took one look and was too surprised to speak. Unexpectedly, this 10-year-old child worked out the correct answer so quickly.

It turned out that little Gauss did not add one by one like other children, but observed carefully, used his head and found the law. He found that the sum of two numbers at the beginning and the end of a figure is the sum of 182 196,50, and182196 can be quickly calculated by multiplication.

Little Gauss's incredible mathematical talent made Butner admire and feel guilty. From then on, he never looked down on children from poor families. He bought many math books for little Gauss and asked his young assistant Battier to help little Gauss learn math. The king asked the goldsmith to make a new one.

. But he suspected that the goldsmith had adulterated the gold crown. Well done, though.

There is no problem in terms of weight or appearance. The king handed the question to him.

Think about it day and night. One day, he went to the bathhouse to take a bath. When he sat down in the bathhouse slowly, the water overflowed from the basin. He looked at the overflowing water and suddenly shouted, "I know!" " "unexpectedly.

Run home quickly. It turned out that he had come up with a way.

Ba Jin

Put it in a jar full of water, and some water overflowed. He picked up the crown, filled it with water and put it together.

A piece of gold was put into the water, and some water overflowed. He compared two kinds of water and found that the first one overflowed more than the second one. So he decided to mix the gold crown with silver. After the experiment, he worked out the weight of silver. When the goldsmith announced his discovery,

The significance of this experiment is far greater than finding out that the goldsmith cheated the king. Archimedes discovered the principle that the weight of an object in a liquid is equal to the weight of the liquid he discharged. This principle is named after Archimedes. Until modern times, people are still using this principle to determine.

Wait a minute.

Team enters Syria

I broke into Archimedes' house and saw an old man working on the ground.

The soldier trampled on the painting. Archimedes angered the soldiers: "Don't break my picture!" " The soldiers withdrew.

, stabbed the unparalleled great scientist, Archimedes died of stupid and ignorant Lomono.

I have it. The above is what I provided after searching for reference. Satisfied, please adopt.
