1966, Chen Jingrun, who lives in a 6-square-meter hut, borrowed a dim kerosene lamp, leaned against the bed board and used a pen to consume several sacks of draft paper. He actually conquered (1+2) in the world-famous mathematical puzzle "Goldbach conjecture", creating a distance from taking off the crown jewel of number theory (1+66). He proved that "every big even number is the sum of the products of a prime number and no more than two prime numbers", which made him a world leader in Goldbach's conjecture research. This result is called "Chen Theorem" internationally and is widely quoted. This work also enabled him, Wang Yuan and Pan Chengdong to win the first prize of China Natural Science Award with 1978 * *. His achievements in studying Goldbach conjecture and other number theory problems are still far ahead in the world. World-class master of mathematics, American scholar? Will (a? Weil) once praised him like this: "Every job in Chen Jingrun is like walking on the top of the Himalayas.

Second, the mathematician Rudolph's short stories

/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.

Third, the mathematician Jacob Bernoulli's short stories.

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.

Fourth, the short story of mathematician Archimedes

Some mathematicians devoted themselves to mathematics before their death, and after their death, they carved symbols representing their life achievements on tombstones.

Archimedes, an ancient Greek scholar, died at the hands of Roman enemy soldiers who attacked Sicily. ), people carved the figure of the ball in the cylinder on his tombstone to commemorate his discovery that the volume and surface area of the ball are two-thirds of that of the circumscribed cylinder. After discovering the regular practice of regular heptagon, German mathematician Gauss gave up the original intention of studying literature, devoted himself to mathematics, and even made many great contributions to mathematics. Even in his will, he suggested building a tombstone with a regular 17 prism as the base.

One day, Sasuke was caught by orochimaru. Both Woody Sakura and Naruto tried to save him, but Lord Gang Shou, the fifth generation of Naruto, refused, saying, "I can understand your feelings of saving Sasuke, but it's too risky. Unless you can surpass me. " Naruto rolled up his sleeves and said, "Come on!" Gang Shou said, "This is a mathematical problem. Listen, there are ten monkeys on a tree. Three monkeys come down, five monkeys go up, one monkey dies and two monkeys are born. How many monkeys are there in the tree now? " Naruto is very few,10-3+5-1+2 =13. "Gang Shou fulfilled his promise and released Naruto and Woody Sakura.

When they arrived at orochimaru's lair, the door said, "If you want to save people, you must answer the following math questions. 1). There are 90 chickens and 270 ducks on the farm. How many times is a chicken as a duck? 2). How many times is a duck a chicken? "

Naruto calculated and replied, "Chicken is duck's 1/3, and duck is three times as big as chicken." So they passed the first level. Then they went to the next level, and they wanted to go through it again. After this, they can rescue Sasuke.

"Please listen to the question. The piano of a poor family should have 88 keys, but 39 keys are missing. After someone installed the 10 key, how many are there now? " Woody Sakura quickly replied: "88-39+ 10=59." They finally rescued Sasuke and went back happily.
