1796 One day, at the University of G? ttingen in Germany, a 19-year-old young man finished his dinner and began to do two routine math problems assigned to him by his tutor. As usual, the first two questions were successfully completed within 2 hours. But the young man found that the tutor assigned him an extra question today. The third question, written on a small piece of paper, is to make a positive 17 polygon with only compasses and an uncalibrated ruler. He did it without thinking much. However, young people feel very hard.

At first, he thought, maybe my tutor made it harder for me. However, with the passage of time, no progress has been made on the third question. Young people rack their brains and feel that the knowledge of mathematics they have learned is of no help in solving problems. Difficulties aroused the young people's fighting spirit: I must do it! He picked up the compass and ruler, drew on the paper, and tried to solve the problem with some unconventional ideas ... When there was a glimmer of light outside the window, the young man breathed a sigh of relief, and he finally worked out the problem! Young people feel a little guilty and blame themselves when they meet their mentor. He said to his tutor, "I did the third question you assigned me all night, and failed to live up to your cultivation ..." The tutor took over the students' homework and was immediately shocked. His voice trembled and said, "Did you really ... make it yourself?" The young man looked at the excited tutor with some doubts and replied, "Yes, but I was so stupid that it took me a whole night to make it."

The tutor asked him to sit down, took out compasses and rulers, spread the paper on the table, and let the young people do the questions in front of him. The young man solved the problem quickly. The tutor excitedly said to the young man, "Do you know that you have solved a math problem with a history of more than 2,000 years? Newton didn't solve it, Archimedes didn't solve it, and you solved it overnight! You are a genius! I have been studying this difficult problem recently. When I assigned you a topic yesterday, I accidentally put a small note with this topic in the topic for you. " Later, whenever the young man recalled this incident, he always said, "If someone told me that this is a math problem with a history of more than 2,000 years, I might not be able to solve it. This young man is Gauss, the prince of mathematics.

Comments: Most children rarely think of obeying the rules and are rarely afraid. Some things, when it is not clear how difficult, children can often do better. In fact, fear of difficulties is not difficulties, but fear of oneself and lack of confidence in oneself. Therefore, in the process of educating children, don't instill fear of difficulties in children with your own eyes; Children should be encouraged to think, do and build self-confidence.
