Teacher Fang asked Axi in math class, "What's the difference between one-half and one-eighth?" An Xi: "More than half". Teacher Fang said, "Think about it. If you had to choose half an orange or eight sixteenth oranges, which one would you choose? " Axi: "I must have half." "Why?" "A lot of orange juice has been squeezed dry when the oranges are divided into one sixteenth, don't you think so, teacher?"

The story of mathematicians:

Gauss regular heptagon

If you were asked the problem of a regular heptagon, which mathematician solved it first? You will definitely say the answer without hesitation, but do you know how he did it? You have to guess this, and the answer you guess must be: Like ordinary mathematicians, everyone wants to solve eternal problems, and then get the answer after careful and unremitting research. Sorry, your answer is wrong.

The story goes something like this: One day in 1796, at the University of Goergen in Germany, a student of 19 years old just finished his dinner and began to do three homework problems given to him by his tutor every day. He solved the first two problems easily, and the third problem is that he asked to draw a regular heptagon with only compasses and an uncalibrated ruler. This problem stumped him-his knowledge of mathematics didn't help him solve it, and the difficulty aroused his fighting spirit. He tried to solve the problem with various ideas. After a night of thinking and pondering, he finally solved the problem the next morning.

When he handed his homework to his tutor, he felt ashamed because he felt that he had spent too long and failed the teacher's hope. But when the tutor finished reading the homework, he was shocked. It turns out that the tutor left the third question wrong. This problem is actually an eternal problem that even Archimedes and Newton failed to solve all their lives. It only took the student one night to do it. This student is the prince of mathematics-Gauss.
