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.

Gauss, the prince of mathematics, was very naughty when he was a child. As a result, the teacher wanted to make things difficult for him, saying that if he could work out 1+2+3+…+ 100, he wouldn't be punished. In fact, the teacher doesn't know the result either. When Gauss answered 5050 quickly, the teacher could not judge whether it was right or wrong. It turned out that Gauss was right. Therefore, the first n terms of arithmetic progression and their solutions are studied.
