Gauss is a sophomore in primary school. One day, because his math teacher had handled more than half of the things, he still wanted to finish them even though he was in class, so he planned to give the students a math problem to practice. His topic is:1+2+3+4+5+6+7+8+9+10 =? Because addition has just been taught for a long time, the teacher thinks it will take a long time for students to work it out, so that they can use this time to deal with unfinished things. But in the blink of an eye, Gauss had stopped writing and sat there doing nothing. The teacher was very angry and scolded Gauss, but Gauss said he had worked out the answer, which was 55. The teacher was shocked and asked how Gauss worked it out. I just found that the sum of 1 and 10 is the sum of1,2 and 9, 1 1, 3 and 8, 1 1, 4 and 7. And11+1+1+1+11= 55, that's how I worked it out. Gauss became a great mathematician when he grew up. When Gauss was young, he could turn difficult problems into simple ones. Of course, qualification is a big factor, but he knows how to observe, seek the law, simplify the complex, and is worth learning and emulating. ?
Second, the mathematician Chen Jingrun's short stories
Mathematician Chen Jingrun was thinking while walking, and bumped into a tree trunk and said, "I'm sorry, I'm sorry." Keep thinking.
Third, the mathematician Thales' short stories
Thales (an ancient Greek mathematician and astronomer) came to Egypt. People wanted to test his ability, so they asked him if he could measure the height of the pyramids. Thales agreed, but on one condition-Pharaoh must be present. The next day, Pharaoh arrived as scheduled and many onlookers gathered around the pyramid. Before Cyrus came to the pyramids, the sun cast his shadow on the ground. Every once in a while, he asked someone to measure the length of his shadow. When the measured value is completely consistent with his height, he immediately made a mark on the projection of the Great Pyramid on the ground, and then measured the distance from the bottom of the Pyramid to the projection spire. In this way, he reported the exact height of the pyramid. At the request of Pharaoh, he explained how to push the principle from "shadow length equals body length" to "tower shadow equals tower height", which is today's similar triangles theorem.
