Academician of the Academy of Sciences. I met Euler, a great mathematician, in Goldbach, and they exchanged letters for more than 30 years. He has a famous conjecture, which was put forward in his correspondence with Euler. This has become a popular story.
When I was in Central China, in a math class, the teacher gave the students a famous question: "There is a number, three places, and two; 5 digits, 5 numbers, and the remaining 3; There are seven places in seven, and there are two left. What's the date? " While everyone was thinking, Hua stood up and said, "23". His answer surprised the teacher and won his praise.
On one occasion, Chen Jingrun went for a haircut. He is the 38th, and there is still a long way to go! So he went to the library and forgot to get a haircut. Brand 38 is still in his pocket!
Mathematicians fall in love
Mathematicians and their girlfriends are walking in the park. His girlfriend asked him, "Do you really mind my freckles?" The mathematician replied softly, "Absolutely not! I was born to like dealing with decimal points. "
Love circle
A young man and a young woman are sitting on the beach. The young man drew a circle on the ground and said, "My love for you, like this circle, will never end." The young woman also drew a circle on the ground with her finger and said, "My love for you will never begin."
abstract
A friend of my friend drank too much at one time in the restaurant. It's almost an hour before business hours. The waiter came to remind you that you can leave. At that time, the Great Xia said a very shocking sentence. He said so. "Don't mess with me, or I'll beat you in the abstract."
Mathematicians' humor
A statistician met a mathematician, and the statistician teased the mathematician and said, didn't you say that if X = Y and Y = Z, then X = Z! Then I think if you like a girl, then you will also like the boy that the girl likes! ? "The mathematician thought for a moment and asked," Then if you put your left hand in a pot of 100 degree boiling water and your right hand in a pot of 0 degree ice water, that's fine! Because they are only 50 degrees on average! "
polygraph
Dad has a polygraph. He asked his son, "How was your math today?" The son replied, "90 points." The polygraph rang. The son added, "70 points." The polygraph is still ringing. Dad shouted angrily, "I used to get more than 90 points." At this time, the polygraph fell down without sound.

The professor is a kind and humorous old man, and there is a tall and strong PE student in his class. Every time the professor's voice rings in class, the PE students start to sleep until they wake up on time after class. One day, the sports student was late, and the professor kindly said to him, "Jack, please don't be late in the future, it will affect your normal sleep."
count
My son is three years old. He already knows how to count from one to ten, and he also knows that five is bigger than one. I also look for opportunities to teach him at any time and ask him which is bigger, the dog or the kitten. Once, I took a chocolate in my left hand and two chocolates in my right hand and asked him, "Which side is more?" . My son didn't answer, so I continued to ask patiently. The son burst into tears and said, "There are few faces!" "
The application of logic
A student asked Einstein what was the use of logic. Einstein asked him, "Two people climbed out of the chimney. One had soot on his face and the other was clean. Which one do you think should take a bath? " "The dirty one, of course." The student said. "No .." Where will the dirty one take a bath when he sees the other person clean and thinks he won't be dirty either? "
Interesting job search
Chen Liyan went to apply for a job. The manager asked him, "How much salary do you ask for a year?" "According to my working ability, I should be able to earn an annual salary of 1.8 million yuan," Chen Liyan said. The manager stared at him for a while before saying, "Is the annual salary of 18,000 worth it? Is it clear? There are only 365 days in a year. If you sleep eight hours a day, a year is 122 days. 365 days minus 12 1 day. Furthermore, you have eight hours of rest and entertainment besides going to work in the mountains every day, which means 122 days a year. Then subtract 12 1 day from 243 days, leaving only 12 1 day. But there are 52 weeks in a week, and there is no work on Sundays, so 12 1 day subtracts 52 days to leave 69 days. At the same time, every Saturday afternoon is a holiday, so there are 26 days in a year, so 69 days MINUS 26 days leaves 43 days. Minus the two-week annual leave given by the company, there are only 29 days left. Don't forget to have an hour's lunch every day, which means 15 days a year. 29 MINUS 15, leaving 14 days. Excluding public holidays such as the new calendar year, the old calendar year, Mid-Autumn Festival, Easter, Thanksgiving, Christmas *** 10, that is to say, I only work four days a year. Do you think it's worth 18 thousand? "
The professor said ....
One day, a professor suddenly stopped teaching and told everyone earnestly: if the students sitting in the middle can be as quiet as the students sitting in the back playing cards, then the students sleeping in front will not be disturbed.
check tickets
The old professor travels by train. When the conductor came to check the ticket, he couldn't find it. The old professor was sweating with anxiety. The conductor said, forget it, just make up a ticket. Old Professor: How did this happen? I don't know where I'm going until I find that ticket!
The mystery of the inscription
Diao Fandu, a famous mathematician in Alexandria, ancient Greece, is only known as a man in the 3rd century A.D., but his age and life history books are not clearly recorded. However, we can still learn a thing or two from his tombstone, which tells people all the year round that he is 84 years old. The tombstone of Diao Fandu is like this: Diao Fandu was buried here. If you understand the mystery of the inscription, it will tell you the life of the diaojiao building. The gods gave him 1/6 of life as his childhood. After112 of life, he grew a beard, and then Diao Fan got married, but he had no children, so he spent 1/7 of life. Five years later, he had his first son, but his beloved son died young.
Questions and answers
Teacher: "I give my classmates two questions." The person who answers the first question does not need to answer the second question. Now I ask the first question: Who knows how many hairs they have? " Xiaoli: "I know, I have 99,999 hairs." Teacher: "How do you know?" Xiaoli: "Teacher, this is the second question. You can't ask me to answer. "
Paradox problem
I am discussing a paradox with my classmates: the only barber in the village has to cut the hair of those who don't, and ask who the barber is. It's really hard! Barbers cut their own hair, so they cut their own hair. A barber won't cut his own hair unless he cuts his own. How profound! The discussion was fruitless for a long time. The classmate in the back row inserted a sentence: "This is not simple, the barber is bald!" "
How many times?
The teacher asked in class, "/kloc-How many wars happened in Spain in the 5th century?" "Six times." A student answered quickly. "Which six times?" The teacher asked again. "The first time, the second time, the third time, the fourth time, the fifth time and the sixth time."
mathematician
There are two kinds of mathematicians in the world: those who can count and those who can't. There are two kinds of people in the world: those who believe there are two kinds of people in the world and those who don't. There are two kinds of people in the world: those who can be classified as one of them and those who can't.
