Mathematical short story handwritten newspaper

"One" short math stories and games (to be written in the handwritten newspaper).

Speaking of Poisson's bright spots is really interesting. In the period of classical physics, there were two views on the nature of light, namely, wave power theory and particle theory (of course, it is now known that it is actually wave-particle duality). Poisson, a mathematician, is a staunch particle theorist, and he despises the theory of light fluctuation. As we know, waves can be diffracted, so Poisson used a rigorous mathematical method to refute the wave theory of light, and came to the conclusion that "if light is a wave, a bright spot will appear in the shadow center behind it when it shines on a disk with appropriate size", which was a ridiculous conclusion at that time. The center of the shadow should be the darkest, but if the light is fluctuating, it will become the brightest place. Poisson thinks that this conclusion can completely overturn the theory of light wave, but the experiment of physicist Fresnel surprised Poisson-indeed, there is a bright spot in the center of the shadow.

Poisson wanted to overthrow the theory of light wave, but the result proved the wave of light again. Because the bright spot in the disc diffraction was first proved and calculated by Poisson, it is called "Poisson bright spot"

"II". It is a story about mathematicians, and it is written by hand.

1. Chen Jingrun doesn't like playing parks, doesn't like strolling around the streets, but loves learning. When I study, I often forget to eat and sleep.

One day, when Chen Jingrun was having lunch, he felt his head. Alas, 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 put down his job and ran to the barber shop.

There are many people in the barber shop, so everyone cuts their hair next to each other. Chen Jingrun's brand is a small brand number 38. It's still early for my turn, he thought. How precious time is, I can't waste it in vain. 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 foreign languages. He recited it for a while, and suddenly remembered that when he was reading a foreign language in the morning, there was a place he didn't understand. If you don't understand something, you must understand it. This is Chen Jingrun's temper. He looked at his watch. It was 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, it's not long after he left, and it's his turn to get a haircut. The barber's uncle shouted, "No.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 some time, Chen Jingrun learned what he didn't understand in the library, and then he walked happily to the barber shop. 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 a book again. He didn't remember the haircut until the sun went down. As soon as he touched his pocket, the small sign number 38 was still lying well. But what's the use of him coming to the barber shop? This number is out of date.

2. Archimedes

King Helo of Syracuse asked a goldsmith to make a crown of pure gold, and because he suspected that there was silver in it, he asked Archimedes to identify it. When he entered the bathtub to take a bath, the water overflowed outside the bathtub, so he realized that although objects of different materials have the same weight, the water discharged will be different because of their different volumes. According to this truth, we can judge whether the crown is adulterated.

3. Hua Luogeng (November 12, 191—June 12, 1985), a world-famous mathematician, was the founder and pioneer of China's analytic number theory, matrix geometry, canonical groups, self-safe function theory and many other studies. The international achievements in mathematical research named after Fahrenheit include Fahrenheit Theorem, Wye-Hua Inequality, Fahrenheit Inequality, PuLawwill-Gardiner Theorem, Fahrenheit Operator and Hua-Wang Method.

4. In 1966, Chen Jingrun, who lived in a 6-square-meter hut, borrowed a dim kerosene lamp and leaned on the bed board, using a pen, and consumed several sacks of draft paper. He actually conquered (1+2) in the world-famous mathematical puzzle "Goldbach Conjecture" and created a brilliance that was only one step away from picking up the pearl in the crown of number theory (1+ 1). 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 the study of Goldbach conjecture. This result is internationally known as "Chen's Theorem" and has been widely cited. This work also enabled him to win the first prize of China Natural Science Award together with Wang Yuan and Pan Chengdong in 1978. His achievements in studying Goldbach's conjecture and other number theory problems are still far ahead in the world. A world-class master of mathematics and American scholar A Will (A? Weil) once praised him like this: "Every job in Chen Jingrun is like walking on the top of the Himalayas.

----------I am the dividing line. Looking at it, I couldn't help exclaiming: "Which country is this Hua Luogeng?" The people around him shook their heads. "Which university does he teach at?" People looked at each other. Finally, a Jiangsu-born teacher thought for a long time before slowly saying, "My brother has a fellow named Hua Luogeng. Where did he teach at any university?"! He only attended junior high school, and I heard that he worked as a clerk in Jintan Middle School. "

Xiong Qinglai was amazed. A junior high school graduate must be a genius to write such a profound mathematical paper. He immediately made a decision to invite Hua Luogeng to Tsinghua University.

From then on, Hua Luogeng became an assistant in the Department of Mathematics of Tsinghua University. Here, he is like a duck to water, swimming in the ocean of mathematics every day, leaving only five or six hours of sleep for himself. It's hard to believe that Hua Luogeng even developed the habit of reading books after turning off the lights. Of course, he has no special function, just a logical thinking activity in his mind. He took a book under the lamp, looked at the topic and thought for a while, then turned off the light and lay in bed, closed his eyes and meditated, and began to do the problem in his mind. When you encounter difficulties, turn over and get out of bed, and open the book for a while. In this way, a book that takes ten days and a half months to finish, he finished it in one night and two nights. Hua Luogeng is regarded as an unusual assistant.

in the second year, his papers began to be published in famous foreign mathematical magazines. Tsinghua University broke the precedent and decided to promote Hua Luogeng, who has only junior high school education, to teaching assistant.

A few years later, Hua Luogeng was sent to Cambridge University in England. However, he doesn't want to study for a doctorate, but only wants to be a visiting scholar. Because being a visiting scholar can break through the shackles and study seven or eight subjects at the same time. He said: "I came to England to study, not to get a degree."

Hua Luogeng didn't get a doctorate. During his two years in Cambridge, he wrote 2 papers. On the level, each article can get a doctorate. In one of the studies on "the problem in the tower", his theory was named "Fahrenheit Theorem" by the mathematical community.

Hua Luogeng devoted himself to his beloved mathematical research with a spirit of loving science, studying diligently and not seeking fame and fortune. He abandoned the money, fame and position sought by the world. In the end, his career succeeded.

Hua Luogeng closely combines scientific research with practical application. Hua Luogeng applied mathematics to industrial and agricultural production, and made outstanding contributions to China's modernization drive.

In the mathematical kingdom, the number "1" is the one that people despise most. Talking about looks, "1" is thin and lonely, like a match stick; In terms of size, she is the smallest of natural numbers. People ignore her all day.

When Infinitus became king, the first thing he did was to host a performance meeting for "1". He said to "1", "Show your skills to everyone then, and people will not underestimate you." "1" listened to the king's words, and his heart was very warm.

Besides, the citizens of the kingdom of mathematics are all amused to hear that "1" is going to hold a performance, so we have to see what happened.

the "1" performance was held as scheduled.

In the music, I saw "1" coming with a handstand first. "1" introduced myself: "The reciprocal is still the original face. Among the natural number brothers, I am the only one." Just finished, "9" jumped on the stage and said, "What is this? I also have 1/9 of the countdown brothers. " "1" smiled and said, "Is your countdown still your original face? ""9 "suddenly blindsided. Oh, you see, this is the stunt of "1".

"1" went on to say, "Not only that, any one of you who multiplies with your penultimate brother will get my" 1 "in the end, and any one of you who multiplies with me or yourselves, 5 times 1 equals 5, and 6 times 1 equals 6."

It turns out that "1" has a lot of tricks! Everyone talked about it.

"1" added: "I am in the kingdom of scores, and my role is also great. Who can say?"

Miss Zero spoke: "I remember using you as a standard to judge the true and false scores."

"No." "5" expressed a different opinion: "A true score is a score whose numerator is less than the denominator, and a false score is a score whose numerator is greater than or equal to the denominator, which has nothing to do with' 1'."

"1" smiled and asked, "Isn't the value of the fraction whose numerator is smaller than the denominator definitely smaller than" 1 "? Isn't the value of the fraction whose numerator is greater than or equal to the denominator definitely greater than or equal to' 1'? "

everyone said with one voice, "Yes! You can use' 1' as a standard to judge the true and false scores. "

"1" said proudly, "I am the leader of the army of natural numbers, or I am the first if I don't count. Please watch the following performance. " She counted a bunch of things again: "One, two, three, four, five ..."

"Brothers of natural numbers, you are either a composite number or a prime number. Only I am not a prime number or a composite number." "1" then invited several natural number brothers to perform together. As a result, some have other divisors besides 1 and itself, and some only have two divisors: 1 and itself.

after the performance of "1", "9" took the lead in clapping and congratulated "1" on its success.

The king "∞" said with emotion: "After watching the performance of' 1', I know her special skills, and her role is very great. In fact, without' 1', there would be no natural number, including me, which is also composed of an infinite number of' 1'!"

"Si" primary school fourth grade makes handwritten newspaper interesting stories about mathematics

Some mathematicians devoted themselves to mathematics during their lifetime, and after their death, their tombstones are engraved with symbols representing their life achievements.

after Archimedes, an ancient Greek scholar, died at the hands of Roman enemy soldiers who attacked Sicily (he still said before his death: "Don't break my circle"), people carved the figure of the ball inscribed in the cylinder on his tombstone to commemorate his discovery that the volume and surface area of the ball were two-thirds of the volume and surface area of its circumscribed cylinder.

The German mathematician Gauss gave up his original intention of studying literature and devoted himself to mathematics after he discovered the rule practice of regular heptagon, and even made many great contributions to mathematics. Even in his will, he suggested to build a tombstone with a regular 17-sided prism as the base.

Rudolph, a 16th century German mathematician, spent his whole life calculating pi to 35 decimal places, which was later called Rudolph number. After his death, others carved this number on his tombstone. Jacques Bernoulli, a Swiss mathematician, studied the spiral (known as the thread of life) before his death. After his death, a logarithmic spiral was engraved on the tombstone, and the inscription also said: "Although I have changed, I am the same as before." This is a pun that not only describes the nature of spiral but also symbolizes his love for mathematics.

5. Diophantus (about 246~33): Diophantus was a mathematician in ancient Greece. He has made great contributions to the development of algebra.

Diophantine wrote Arithmetic, with thirteen volumes. These books have collected many interesting questions, and each question has unexpectedly ingenious solutions, which arouse people's brains and enlighten people's wisdom, so that future generations call this kind of question Diophantine problem. However, little is known about Diophantine's life. His only resume was found in the Collection of Greek Poetry. This is the "epitaph" of Diophantine written by Mattel. The "epitaph" is written in the form of poetry:

passers-by!

Diophantine is buried here.

Please count the following numbers,

and you will know how many winters and summers he has experienced in his life.

One sixth of his life was a happy childhood, and one twelfth was a carefree teenager.

After one-seventh of his life journey,

he has established a happy family.

Five years later, my son was born.

Unexpectedly, my son died four years before his father.

He was only half as old as his father.

Poor old man who lost his son in his later years.

He spent his twilight years in grief.

Please figure out how old Diophantine lived before

meeting death. (If you can't figure it out, the answer can be known from the date of his birth and death.) maclaurin, a British mathematician, was discovered and cultivated by Newton. His tombstone is engraved with the following six characters: Thanks to Newton's recommendation, I hope to adopt the story of the "Wu" mathematical handwritten newspaper. How to write it? < P > What happened in the mathematical handwritten newspaper: Little Euler's father decided to build a new sheepfold. He measured a rectangular piece of land with a ruler, 4 meters long and 15 meters wide. He calculated that the area was exactly 6 square meters, with an average of 6 square meters for each sheep. When he was about to start construction, he found that his materials were only enough for a 1-meter fence, not enough. If the sheepfold is 4 meters long and 15 meters wide, its circumference will be 11 meters. Father felt very embarrassed, but little Euler told his father that all he had to do was move the post of the sheepfold slightly. He shortened the original 4-meter side length to 25 meters centered on a wooden stake. The side length of the original 15 meters was extended, and it was increased by 1 meters to become 25 meters. After such a change, the original planned sheepfold became a square with a side length of 25 meters. Father put up a fence according to the sheepfold designed by little Euler. The 1-meter-long fence is really enough, and the area is enough, and it is slightly larger. Father felt very happy. Later, Euler became a famous mathematician in the history of mathematics.
