(1) Descartes' mathematical story is 200-300 words.

Spider; Spider-like objects; Star wheel; Cross; Connecting handle; crosshead

16 19, Descartes was in the military camp in Newburg, a small town in southern Germany on the Danube. This is a turning point in his life. He is immersed in deep thinking all day, thinking about mathematics and philosophy. 1619165438+1October 10. During the day, Descartes was ill and stayed in bed according to the doctor's advice. Suddenly, Descartes' eyes lit up and a spider crawling on the ceiling caught his attention. In the eyes of ordinary people, this spider may be too ordinary to be ordinary. It is busy weaving a net near the corner of the ceiling. It suddenly climbed up and down the wall and moved slowly in the air in the direction of silk.

Descartes was interested in this spider because he was thinking about solving geometric perfect numbers by algebra, but he encountered a difficulty, that is, how to represent points in geometry with several numbers in algebra? At night, his heart was filled with great excitement, and he fell asleep with a happy and anxious mood, which made him have nightmares and his mood could not be calm for a long time. Early in the morning, thinking of this spider hanging in mid-air, Descartes was suddenly enlightened in his meditation: Can we use the intersection of two walls and the intersection of the wall and the ceiling to determine its spatial position? He slipped down from the bed and drew three vertical straight lines on the paper, indicating the intersection of two walls and the intersection of the wall and the ceiling. Using a point to represent a spider in space can of course measure the distance from this point to three planes. In this way, the position of the spider in the air can be accurately marked. Descartes wrote: "The next day, I began to understand the basic principle of this amazing discovery." This means that he got the clue to establish analytic geometry.

Later, the coordinate system composed of such two perpendicular lines was called Cartesian coordinate system.

Mathematics is really wonderful.

Last semester, our teacher Zhu taught us simple algorithms.

At first I thought: What is simple calculation? I came to school with curiosity. Teacher Zhu said, "A simple algorithm is to change a difficult formula into a very simple formula, such as 25X 16. If you use a pen to calculate, it may take 1 minute, but if you use a simple algorithm, it will be soon. Divide 16 by 4X4, and it is easy to calculate: 25x4x4 = 100x4. When I came home from school, my mother gave me a simple algorithm that we had learned: 35X 12=? I said, "Divide 12 by 2X6 and 2X35 to get an integer, and 35X 12=35X2X6=420. "What, am I smart?

It seems that mathematics is really useful in life! I must learn math well.

(3) 250 to 300 words for the mathematician's story.

1, Zu Chongzhi strives for perfection.

Zu Chongzhi was an outstanding mathematician and astronomer in the Southern and Northern Dynasties. In Zu Chongzhi's time, abacus did not appear, and the commonly used calculation tool was called calculation. It is a square or flat stick several inches long, made of bamboo, wood, iron, jade and other materials.

Different calculation and financing methods are used to represent various numbers, which is called financing algorithm. If there are more digits, the larger the area needs to be placed.

It is not like using a pen to calculate with a calculation formula, it can be left on paper, and every time the calculation is completed, it must be swung again for a new calculation; You can only write down the calculation results with notes, and you can't get more intuitive graphics and formulas.

So as long as there are errors, such as calculation errors or calculation errors, we can only start from scratch.

In order to get the accurate value of pi, Zu Chongzhi needs to calculate the decimal of nine significant figures, including more than ten steps of addition, subtraction, multiplication, division and square root operation, and each step has to be repeated for more than ten times and 50 times of square root operation, and finally the calculated number reaches 16 or 17 digits after the decimal point.

2. Hua's wonderful story

Hua is an academician and mathematician of China Academy of Sciences. 1953, China Academy of Sciences organized a delegation to go abroad, headed by scientist Qian Sanqiang. Members include Hua, Zhao Jiuzhang and Zhu Xian. In his spare time, Hua wrote a couplet: "The top three are Korea, Zhao and Wei", seeking this couplet.

The "top three" here refers to Korea, Zhao and Wei San during the Warring States Period, but it implies the name of the head of the delegation, Comrade Qian Sanqiang, which not only solves the traditional difficulty of the couplet of numbers and numbers, but also requires the name of another scientist to be embedded in the bottom couplet.

After a while, when Hua saw that everyone had no bottom line, he revealed his bottom line: "Hook, strand and string are nine chapters." Nine Chapters is a famous mathematical work in ancient China.

However, the "Nine Chapters" here happen to be the name of another member of the delegation-atmospheric physicist Zhao Jiuzhang. Hua's wonderful pair made the audience fall for it.

1980, when Hua directed the overall planning method and optimization method in Suzhou, he wrote the following couplets: watching chess is not a gentleman, helping each other in the same boat; Be a person with regrets and correct your mistakes.

3. Chen Jingrun's marriage story

Chen Jingrun is a contemporary mathematician. 1977, Chen Jingrun was admitted to 309 Hospital due to illness, and met Yu Kun who had just been sent to the hospital from Wuhan Military Region for further study.

In the past, Chen Jingrun didn't even touch the edge of a woman's name and didn't even say a word. This time, Chen Jingrun, who is nearly half a century old, saw Yu Kun, his eyes lit up, and he greeted Yu Kun kindly, and he talked too much. Later, Kun was sent to the ward in Chen Jingrun as a doctor on duty.

There are more opportunities for such contact. Every time Kun Yi appears, Chen Jingrun is particularly happy. One day, Chen Jingrun asked Youkun with concern, where does he live? Do you have a boyfriend or family? Yu Kun was unprepared and said bluntly, "No, no, it's still early."

Later, Yu Kun also cared about the China mathematician, and they hit it off and fell in love. Finally, one day, Yu Kun asked the mathematicians around him: "You are a great mathematician, and many people worship you. Why did you choose me? "

Facing the beloved girl, Chen Jingrun flushed with anxiety. He doesn't trust young people. It was a long time before Chen Jingrun said, "I thought about it. You don't agree, I will never get married in my life. "

It is this sentence that makes Yu Kun no longer hesitate. She accepted Chen Jingrun's feelings frankly and stayed together for 16 years.

They got married with the help of the organization. Since then, Chen Jingrun, a mathematician known as "idiot" and "eccentric", has a warm home.

Xu Guangqi is an honest official.

Xu Guangqi was a famous scientist and politician in Ming Dynasty. Chongzhen court official, does history, Wenyuange university, cabinet assistant minister. Mr. Xu Guangqi was an honest official and lived a simple life, which was unimaginable at that time.

The bigger the official in Xu Guangqi, the lower the attitude of dealing with people. On Xu Guangqi's 70th birthday, it is customary for officials, relatives and friends to give gifts.

Xu Guangqi has written to tell his classmates in his hometown that all gifts given to him will not be politely declined. Even the gifts from friends and relatives declined politely. The children and grandchildren in Shanghai know the temper and character of the old man and do the right thing.

5. China popularized the duplex method.

While continuing to study mathematical theory, Hua tried to find a way to combine mathematics with industrial and agricultural practice. After a period of practice, he found that the overall planning method and optimization method in mathematics can be widely used in industrial and agricultural production, which can improve work efficiency and change the face of work management.

Therefore, while giving lectures at the University of Science and Technology, he led students to promote the optimization method and overall planning method in industrial and agricultural practice.

At the beginning of 1964, he wrote to * *, expressing his determination to take the road of combining workers and peasants. In March of the same year 18, * * * wrote back: "Poetry and letters have been read. Top gun, congratulations. "

He wrote "Brief Introduction and Supplement to the Master Planning Law" and "Brief Introduction and Supplement to the Optimal Selection Law", and personally led the teachers and students of China University of Science and Technology to some enterprises and factories to promote and apply the "double methods" to serve industrial and agricultural production. "Go to Jianghan to fight the heat in summer and go to Songliao first frost in winter."

This is a portrayal of his life at that time. 1965, * * * wrote to him again to congratulate and encourage him to "work hard and serve the people, not the individual".

④ 200-300 words for math diary.

Today is Saturday. I am at home alone. I woke up at half past eight. I jumped out of bed at once. At this moment, my mother called and told me something. It took me five minutes to answer this call. I quickly changed my clothes, brushed my teeth and washed my face. Then go straight to the table for breakfast. Fifteen minutes later, 15+5=20 (minutes), 8: 30+20 = 8: 50 (minutes), 12: 00-8: 50 = 3: 50 (minutes), and it will be noon in three hours and fifty minutes. At this time, I found that there were no noodles, so I took 30 yuan to go to Xinli Shopping Mall to buy noodles.

When I arrived at the shopping mall, I saw two kinds of noodles for me to choose from, one was 450g, and the other was 400g, which was 2/3 of the price of the first kind of noodles, 4.5÷3= 1.5 (yuan), 1.5×2=3 (yuan), and I ate it alone at home. It suddenly occurred to me that my mother asked me to buy five shuttlecocks at two yuan each, 5×2= 10 (yuan), 10+3= 13 (yuan) and 30- 13 = 17 (yuan).

Return home,10; In 20 minutes, I prepared two eggs first, and then I watched TV.

Time flies to 12: 00, so I quickly beat eggs. After 20 minutes, a bowl of steaming noodles is ready. I wolfed down my noodles and then went to bed for a nap.

I took a nap and woke up at four. My parents will be back in two hours. I’m not doing anything right now. Suddenly I saw a pile of unwashed clothes. I immediately rushed over and started washing clothes.

It takes me five minutes to wash one dress, and there are eight dresses altogether. I divided eight clothes into two piles, 8÷2=4 (pieces), and each pile contained four clothes. It took me a total of 8×5=40 minutes to finish washing clothes, so I had to bite the bullet and wash them down.

It's 5 o'clock after washing clothes, 40 minutes after washing clothes, and more than ten minutes after waking up. My parents came back early, saw what I did and praised my ability!

The experience of "being the master of my own house" was so interesting that it enhanced my self-reliance. Although some simple math problems, but also let me know how to use math knowledge to better manage my parents' finances.

⑤ The story of a mathematician, 200/300 words.

One day, Chen Jingrun touched his head during lunch. Oh, his hair is too long. He should get a haircut quickly, or people will think he is a girl when they see him. So he left work and ran to the barber shop.

There are so many people in the barber shop that everyone cuts their hair next to each other. Chen Jingrun's brand is the small brand number 38. He thought it was too early for me to turn now. Time is so precious that I can't waste it. He hurried out of the barber shop, found a quiet place to sit down, then took out a small notebook from his pocket and recited new words in a foreign language. He recited it for a while and suddenly remembered that when he was reading a foreign language in the morning, there was one place he didn't understand. You must understand what you don't understand. This is Chen Jingrun's temper. He looked at his watch. It's only half past twelve. He thought: check in the library first, and then come back for a haircut. He stood up and left. Who knows, not long after he left, it was his turn to get a haircut. The barber's uncle shouted, "Number 38! Who is number thirty-eight? Come and get a haircut! " Think about it. Chen Jingrun is reading in the library. Can he hear the barber's uncle calling number 38?

After a long time, Chen Jingrun found something he didn't understand in the library, and then went to the barber shop happily. But he passed by the foreign language reading room, and there were all kinds of new books, which were really nice. He ran in and read another book. It was not until the sun went down that he remembered to cut his hair. As soon as he touched his pocket, the little sign No.38 was still lying well. But what's the use of his coming to the barber shop? This number is outdated.

As soon as Chen Jingrun entered the library, it was like falling into a honey pot, and he couldn't bear to leave. Yes, another day, Chen Jingrun had breakfast, took two steamed buns and a pickle, and went to the library.

Chen Jingrun found the quietest place in the library and read carefully. He stayed until noon and felt a little hungry, so he took out a steamed bun from his pocket and was still reading while eating.

"Ding Lingling ..." After work * * rang, the librarian shouted: "After work, please leave the library!" The somebody else all gone, but Chen Jingrun didn't hear, or 1 vigorously in reading.

The librarian thought that everyone had left the library, so he locked the library door and went home.

Time passed quietly and it was getting dark. Chen Jingrun looked out of the window and said to himself, What a strange weather it is today! It's sunny for a while and cloudy for a while. He pulled down the switch wire of the light and sat down to read. Watching, he suddenly stood up. It turned out that he read a book all day and began to understand. Now, he will go back to the dormitory and continue to do the problems he left unfinished yesterday.

Chen Jingrun put the book away and went out. The library is quiet and there is no sound. Hey, where's the janitor? Why doesn't anyone come to read? Chen Jingrun looked at his watch. Ah, it's past eight o'clock in the evening. He pushed open the locked door; He shouted at the door: "Please open the door! Please open the door! " But no one answered.

In normal times, Chen Jingrun will go back to his seat and continue reading until the next morning. But, not today! He's going back to the dormitory to do that unfinished problem!

He went to the telephone and called the office. But there was no answer, only a beep. He dialed this number several times, but no one answered. What shall we do? At this moment, he remembered the secretary of the Party Committee and dialed the telephone immediately.

Chen Jingrun? The party secretary was surprised when he received the phone call. He was overjoyed, looked into it and said with a smile, "Chen Jingrun! Chen Jingrun! You have worked hard, you are really a good comrade. "

The party secretary immediately sent some comrades to the librarian. The door of the library opened and Chen Jingrun said to the librarian, "I'm sorry! I'm sorry! Thank you, thank you! " As he spoke, he ran down the stairs and returned to his dormitory.

He turned on the light and set about solving the problem at once.

Write a math story of about 300 words according to the following passage.

1234567 are seven very common numbers. Looking at these figures alone, most people think of numbers. However, aside from those numbers, every number can make people think.

1 is extreme.

1 is predestined by heaven and praised or devalued by people, but it is always special. When 1 is positive, such as champion, champion, etc. It is praised by people, and many pairs of eyes stare at it with envy, while 1 fully enjoys "once you climb to the top, you will see that other mountains look short under the sky." . However, the higher you climb, the more you are afraid of falling, so 1 works harder than others. If 1 falls, it must fall harder than others. 1 when counting backwards, it's just ridicule. If there are two 1, then it loses its luster and value. "One mountain can't accommodate two tigers".

What a pity

For 2, Heaven is extremely unfair, just one step away, which is far from the treatment of 1. 2 can only live with regrets forever, but when 1 falls, 2 has a chance to go up. In fact, I should feel lucky. After all, I am "below one person and above ten thousand people", and many people are squeezing this seat. However, people grow through hard work. How can they see the rainbow without experiencing wind and rain? Work hard! 2!

3 is luck.

You are really a lucky dog. Only gold, silver and copper are in the top three in the Olympic Games, and the fourth place doesn't even have a brand; In the ancient imperial examination, only the champion, the champion and the flower explorer had proper names, and the fourth place was only anonymous; Some competitions only have the first prize, the second prize and the third prize. The next prize may be a commemorative prize or an encouragement prize, so you also have a certain weight. Don't be too sad!

4 is to make persistent efforts, 5 is to make persistent efforts.

The combination of 4 and 5 is persistent and the least concerned. When people leave praise to the top three, 4 and 5 are enjoying the taste. When 4 and 5 stand up again, you should be careful of the top three. They are often dark horses. If you don't advance, you will retreat, just as the old saying goes: "If you don't advance, you will retreat."

Six and seven are hopeless.

6 and 7 are equivalent to the reciprocal of 1 and the reciprocal of 2. I write about them like this because it can comfort them. There is a story: a man asked another man, "Where did you run in the running race?" "Seventh." "So, how many people took part in the competition?" "Seven." As if it would make people look better on their faces. The reason why they are written together is that almost no one will think there is any difference between the penultimate 1 and the penultimate 2, unless the penultimate 2 is itself.

1234567, in fact, they are all the same, but people have given them different meanings, which makes them intriguing.

7 Mathematicians' stories will be 200 to 300 words tomorrow! ! ! !

Gauss is a German mathematician, physicist and astronomer. Although he was born in poverty when he was a child, he was able to enter the school with the support of nobles, but his power did not stop his interest and talent in mathematics. His most famous story is that when he was ten years old, the primary school teacher gave an arithmetic problem: "Calculate 1+2+3 …+ 100 =?" . This is very difficult for students who have just learned arithmetic. Many students began to add and sum step by step. Only Gauss thought for a moment and soon worked out the answer. It is by using arithmetic progression's symmetry that he found that the sum of the first and second digits in this addend of 100 is 10 1. That is,1+100 =1,2+99 = 10 1, 3+98 =10/,kloc-0/.

I want a story about mathematics, 200-300 words, interesting and not too boring. I hope it can be faster. Thank you.

one

Three people went to live, and the owner had only one room left. Offer 30 yuan, three people each pay 10 yuan to stay. The price department came to check and found that the shopkeeper overcharged 5 yuan, because a room only needed 25 yuan a night, so he ordered the shopkeeper to return 5 yuan to three guests immediately. The shopkeeper gave the waiter 5 yuan money and asked the waiter to return it to the three men. When the waiter got the money, he thought, it is impossible to divide it equally if five yuan is given to three people. He simply took 2 yuan himself and left 3 yuan for the three of them to share. So he took 2 yuan and gave 3 yuan to the residents, and each resident got back 1 yuan.

Here comes the problem. At the beginning, each guest paid 10 yuan, and each waiter paid 1 yuan. In other words, each guest actually paid 9 yuan, and three guests should be 27 yuan. If you add 2 yuan taken away by the waiter, it is 27+2=29 yuan. So where did the remaining 1 yuan go?

two

A Shanghainese is shopping in the countryside. He asked the stall owner, how much is a pack of instant noodles? The stall owner said, 3 yuan. The Shanghainese said again, then bring me a pack. The stall owner gave him a bag, and then the Shanghainese asked, how much is your bottle of mineral water? The stall owner said, 1.50 a bottle. The Shanghainese said, well, exchange this bag of instant noodles for two bottles of mineral water. The vendor changed it for him. He took two bottles of water and wanted to leave without paying. The stall owner stopped him and said, pay! Shanghainese said, why give money? The stall owner said that if you take something, you have to pay! Mineral water money! ! Shanghainese say mineral water for instant noodles! ! The stall owner said that the money for instant noodles was not paid! The Shanghainese said, I returned the instant noodles to you! Then he left, and the stall owner didn't stop him. He always thinks there is something wrong.

three

A farmer sells crabs in the street, with a total of 10 kg of crabs, one kg 100 yuan. If all of them are sold, there should be a turnover of 1000 yuan. At this moment, I passed a Shanghainese. The Shanghainese said, I like to eat crab feet, and my wife likes to eat crab bodies. I want to buy them separately. You break your feet and body and sell them to me. I want them all. So the farmer broke all his feet. At this time, Shanghainese said that the price of feet is cheaper, so I have to sell a catty of feet in 20 yuan and a catty of body in 80 yuan, which adds up to 100 yuan a catty, that's right! So the farmer weighed the crab's feet, a total of 4 pounds, and received 80 yuan; The crab was weighed, weighing 6 Jin, and 480 yuan was collected. The Shanghainese walked away with these crab feet and bodies. Farmers always feel that something is wrong, but they can't say it. I ordered a little money and found that I sold 560 yuan in total, not 1000 yuan.

Pet-name ruby story about mathematics 300 words.

Mapping is everywhere (the concept of mapping is mentioned in the compulsory course of high school mathematics 1).

When children begin to learn to speak, they often make an important discovery: everything in the world has a name. So he has a strong desire to know the names of everything he sees. Because I don't know the name, I can't speak and I can't make all kinds of demands.

What is this? A chair.

What's this?-a car.

What is this? A kitten.

After knowing the name, he is often satisfied, as if he knew everything in the world.

What is a name? This is a mapping from a collection of objects to a collection of sound symbols.

He will also find many mappings:

Streets have names, households have house numbers, shops have signs, and goods have trademarks.

Everyone has a name, adults have a work permit, children have a student ID card, and everyone has a birthday. . . . . . .

Not only are children learning drawing, but so are all the subjects they study at school:

In history class, every historical event should correspond to its cause and age. . . .

In geography class, each province has its output and population. . . . .

In chemistry class, each element corresponds to its atomic weight. . . . .

What we learn in school is nothing more than explaining the correlation between things, and almost all of this relationship can be expressed by mapping.

Attending a math story of 300 to 200 words should be quick, urgent, urgent, urgent, urgent, urgent, urgent, urgent, urgent, urgent, urgent, urgent, urgent.

When does the snail climb up the well?

A snail accidentally fell into a dry well. It lay at the bottom of the well and began to cry. Mass (

Lai) Toad crawled over and whispered to the snail, "Don't cry, little brother! It's no use crying. The shaft wall is too high. If you fall here, you can only live here. I have been here for many years, and I haven't seen the sun for a long time, let alone want to eat swan meat! " The snail looked at the old and ugly toad and thought, "What a beautiful world outside the well! I can never live in a dark and cold well like it! " The snail said to the toad, "Uncle toad, I can't live here. I have to climb up! "How deep is this well?" "Ha ha ha ..., are you kidding! The depth of this well is10m. How can you climb up with such a heavy shell at a young age? " "I am not afraid of suffering, not afraid of being tired. I can always climb out after a while every day! " The next day, the snail ate and drank enough and began to climb the wall. It kept climbing and finally climbed 5 meters at night. The snail was very happy and thought, "At this rate, I can climb up tomorrow night." Thinking about it, it fell asleep unconsciously. In the morning, the snail was awakened by a purr. At first glance, it turned out that Uncle Tu was still sleeping. It was surprised: "How come I am so close to the bottom of the well?" It turned out that this snail slipped 4 meters from the borehole wall after falling asleep. The snail sighed, gritted his teeth and began to climb again. At night, it climbed another 5 meters, but at night the snail slipped another 4 meters. Climb and climb, and finally the strong snail climbed up the well platform. Children, can you guess how many days it will take a snail to climb the drilling platform?
