Mathematician Chen Jingrun was thinking while walking, and bumped into a tree trunk and said, "I'm sorry, I'm sorry." Keep thinking.

The short stories of mathematician Rudolph

/kloc-Rudolph, a German mathematician in the 6th century, spent his whole life calculating pi to 35 decimal places, which was later called Rudolph number. After his death, someone else carved this number on his tombstone.

The Short Stories of Mathematician Jacob Bernoulli

Jacques Bernoulli, a Swiss mathematician, studied the spiral (known as the thread of life) before his death. After his death, a logarithmic spiral was carved on the tombstone, and the inscription also read: "Although I have changed, I am the same as before." This is a pun, which not only describes the essence of spiral, but also symbolizes his love for mathematics.

The story of Hua, a famous mathematician in China: Hua helped his father with business, abacus and bookkeeping when he was a child. At that time, Hua stood in front of the counter, and as soon as the customers left, he buried himself in reading and solving math problems. Sometimes I am in a daze, forget to receive the customer, and even take the calculation result as the payment payable by the customer, which surprises the customer. Whenever something happens that neglects customers, my father is angry and anxious, saying that he is too tired to read the "heavenly book" and wants to burn the book forcibly. When an argument occurs, Hua always clings to the book.

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 Lao Wang, 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.
