1796, a day at the University of G? ttingen, Germany. After dinner, Gauss began to do three math problems assigned by his tutor. He made the first two questions as easy as blowing off dust. The third inscription is written on another small piece of paper: it is required to make a regular heptagon with only compasses and scaleless rulers. This problem stumped him-his knowledge of mathematics didn't help him solve it at all. A minute passed, and the third question made no progress. He racked his brains and tried to find the answer with some unconventional ideas. He finally solved the problem when the window came out at dawn.

He felt ashamed when he handed his homework to his tutor. He said to his tutor, "I worked on the third question you assigned me all night …" After reading the homework, the tutor excitedly said to him, "Do you know? You solved a math unsolved case with a history of more than two thousand years! Archimedes didn't solve it, Newton didn't solve it, you solved it in one night. You are a genius! " It turns out that my tutor has been trying to solve this problem. That day, because he took it wrong, he handed the note with this topic to the students.

After this incident, Gauss recalled: "If someone told me that this is an eternal problem, I may never have the confidence to solve it."

At that time, gauss was only 19 years old, and he was a genius!
