When Gauss was in elementary school, once after the teacher taught addition, because the teacher wanted to have a rest, he came up with a topic for students to calculate. The theme is:
1+2+3+ 。 ..+97+98+99+ 100 = ?
The teacher is thinking, now the children must start class! I used this as an excuse to go out, but Gauss stopped me! ! It turns out that Gauss has worked it out. Little friend, do you know how he did it?
Gauss told everyone how he worked it out: add 1 to 100, and add 100 to 1, adding two lines, that is:
1+2+3+4+ 。 ..+96+97+98+99+ 100
100+99+98+97+96+ 。 ..+4+3+2+ 1
= 10 1+ 10 1+ 10 1+ 。 ..+ 10 1+ 10 1+ 10 1+ 10 1
* * * There are one hundred sums 10 1, but the formula is repeated twice, so the answer is equal to < 5050 & gt.
Since then, the learning process of Gauss Elementary School has already surpassed other students, which laid the foundation for his future mathematics and made him a mathematical genius! You can write multiplication tables, write stories about mathematicians and so on. And you can also write some topics, or interesting mathematics, or you can write information about mathematicians. . . .
The story is like, Zu Chongzhi.
Zu Chongzhi (AD 429-500), a native of Laiyuan County, Hebei Province, was an outstanding scientist in the Southern and Northern Dynasties. He is not only a mathematician, but also familiar with astronomical calendar, machinery manufacturing, music and other fields, and is an astronomer.
Zu Chongzhi's main achievement in mathematics is the calculation of pi, which is 3. 14 15926.
There's some information,

What is the reason for China's victory in the Anti-Japanese War? Victory time of Pingxingguan: 1937. In September, the Eighth Route Army 1 15 Division ambushed and fought, killing more than 1000 people, destroying more than 0/00 cars, more than 200 carts, and seizing 2 guns, 300 boxes of ammunition, more than 0/000 long and short guns and machine guns.
Significance: The victory of Pingxingguan is the first great victory of China since the Anti-Japanese War! It boosted the morale of War of Resistance against Japanese Aggression and enhanced the prestige of the Eighth Route Army. "The first battle was flat, and it was famous in the world." The victory of Pingxingguan also shattered the myth of "invincible imperial army", dealt a blow to the arrogance of Japanese invaders, and refuted the fallacies of traitors and pro-Japanese factions that "war is inevitable" and "war is not as good as peace".
Second, the Battle of Taierzhuang, Taierzhuang, Xuzhou, Linyi, tengxian, the victory significance of the time commander of the semi-original division, Jigu Division 1938 Spring Body Elimination 10000 The first major victory of the Kuomintang army in the early days of the Anti-Japanese War in Li Zongren.
Fourthly, how mathematics was applied to architecture in history. In history, architecture and mathematics have a great connection.
Ancient mathematicians were architects, and vice versa. They built pyramids, temples, ditches, churches and a series of other buildings with superb skills, which we still find beautiful and amazing today. For example, in ancient Greece and Rome, architects must also be mathematicians.
In the Middle Ages, most buildings and structures contained some meanings of church. During this period, the mathematical factors of architecture were almost forgotten. During the European Renaissance of about 1400, a new type of architecture appeared, which emphasized the texture and internal space to produce a beautiful "picture", just like oil painting and sculpture.
This brings a brand-new perspective on architecture and changes the relationship between architecture and mathematics.
V. How to do a good job in ppt of digital stories? Little N story: A swordsman and a K swordsman visited a G Wulin master and asked him how to practice extraordinary R martial arts. Wulin master 5 took out an N dagger that was only one foot 62 long and said, "Thanks to M's good sword, K made me achieve such achievements as R in six days." The swordsman's big k is 7, so I don't know the solution. He asked, "other people's swords are all three r feet, three t inches, n length, 8, and your sword length is 7-0 feet, 6 to 3." On the weapon spectrum, Z said: the sword is one hour shorter and eight points, and the risk is increased by three R and four points. There is no doubt that holding a sword as short as X is bad for J-E. How can you say this sword is good? "Wulin master 1 said:" Because 4 is at the disadvantage of H in weapons, I will always think about how dangerous I will be if I fight L, so 8 I have to practice swordsmanship diligently and make up for W's deficiency with O of 4 swordsmanship. In this way, my swordsmanship will not be broken, and my disadvantages will be turned into advantages. "Indeed, the advantages and disadvantages are absolutely interrelated. To put oneself at a disadvantage in B is to increase the pressure on oneself in Q, to inject the motivation of P into oneself in W, and the person who dares to put himself at a disadvantage in X may eventually turn into a 30% advantage. I already sent it out.

Sixth, the story of mathematicians, how to make PPT When Zu Chongzhi was a child, his grandfather often told stories about scientists. Among them, the story of Zhang Heng inventing the seismograph deeply touched Zu Chongzhi's young mind.
Zu Chongzhi often goes to the construction site with grandpa. In the evening, he often enjoys the cool and plays with rural children. The stars twinkle in the sky. In Zu Chongzhi's view, these stars are scattered in disorder, but rural children can name them, such as Cowherd, Weaver Girl and Beidou. At this time, Zu Chongzhi felt that he really knew very little.
Zu Chongzhi doesn't like reading ancient books. At the age of five, his father taught him to learn The Analects of Confucius, and he could only recite a dozen words in two months.
I was so angry that my father beat and cursed. But he likes math and astronomy.
One night, Zu Chongzhi was lying in bed thinking that the teacher said during the day that "the circumference is three times the diameter" seemed wrong. The next morning, he took out a rope from his mother's shoes and ran to the roadside at the head of the village, waiting for the passing cars.
After a while, a carriage came. Zu Chongzhi stopped the carriage and said to the old man driving, "Let me measure your wheels with a rope, ok?" The old man nodded. Zu Chongzhi measured the wheel with a rope, folded the rope into three sections with the same size, and then measured the diameter of the wheel.
Measured, he always felt that the diameter of the wheel was less than the circumference of 1/3. Zu Chongzhi stood on the side of the road and measured the diameters and perimeters of several carriage wheels continuously, and reached the same conclusion.
Why on earth is this? The problem has been haunting him. He is determined to solve the mystery.
After years of hard study, Zu Chongzhi studied Liu Hui's Split. The so-called "secant" is to draw a regular hexagon in a circle, the side length of which is exactly equal to the radius, and divide it into 12 polygons. Use Pythagorean theorem to find the length of each side, then divide it into 24 and 48 polygons, and keep dividing it. The sum of the side lengths of polygons is the circumference of the circle.
Zu Chongzhi admired Liu Hui's scientific method very much, but Liu Hui only got 96 edges and got 3. After the result of 14 came out, it was not calculated again. Zu Chongzhi is determined to work out 192 polygon and 384 polygon step by step along the road initiated by Liu Hui. So as to obtain more accurate results.
At that time, the number operation was not calculated with paper, pens and numbers, but with small bamboo sticks arranged alternately, and then calculated by an abacus-like method. Zu Chongzhi drew a big circle with a diameter of 1 ft on the floor of the room, made a regular hexagon in it, and then spread out many sticks made by himself and began to calculate.
At this time, Zu Chongzhi's son Zuheng 13 years old also helped his father to work together. It took them more than ten days to get to the 96th border, and the result was 0 less than that of Liu Hui. 000002 feet.
Zuheng said to his father, "We have calculated very carefully. This must be true. Maybe Liu Hui is wrong. " Zu Chongzhi shook his head and said, "To overthrow him, there must be a scientific basis."
So, the father and son spent more than ten days recalculating, proving that Liu Hui was right. In order to avoid further errors, Zu Chongzhi will repeat the calculation at least twice in each step until the results are exactly the same.
Zu Chongzhi from 12288 polygon to 24567 polygon, the difference between them is only 0. 000000 1。
Zu Chongzhi knew that he could continue to calculate in theory, but in fact he couldn't figure it out, so he had to stop here, so pi must be greater than 3. 14 15926 and less than 3.
14 15927。 Many friends know Zu Chongzhi's calculation results and come to him for advice.
Later, Zu Chongzhi further concluded that the density ratio of pi was 355/ 1 13 and the approximate ratio was 22/7. It was not until 1000 years later that the German mathematician Otto came to the same conclusion.
Seven, there are many PPT of mathematicians' interesting stories on the Internet.
For example, the story of mathematician Gauss PPT://wenku.baidu/view/ec992456312b3169a45145d. The short story of famous mathematicians at home and abroad PPT:// Wen Ku. Baidu/View/2ab50aefb8f67c1cfad6b863. Mathematician's story://wenku.baidu/view/a2f74f3a580216fc700afd72. Introduce the story of foreign mathematicians 1840- 1949 PPT:/ article.
8. What is the three-minute math story? I'm going to give a speech tomorrow. Gaussian solution 1+2+3+4+.
.
+100 Goss's story started school at the age of seven. /kloc-at the age of 0/0, he entered the class of learning mathematics, which was the first class established. Children have never heard of such a course as arithmetic before.
The math teacher is Butner, who also played a certain role in the growth of Gauss. One day, the teacher assigned a question, 1+2+3. ...................................................................................................................................................
Gauss quickly worked out the answer. At first, Gauss's teacher Butner didn't believe that Gauss had worked out the correct answer: "You must have miscalculated. Go back and do it again. " Gauss is determined, and the answer is 5050.
The calculation method of Gaussian is as follows:1+100 =1,2+99 =10/kloc-0+51=/kloc-0. There are 50 groups of such numbers from 1 to 100, so 50X 10 1=5050.
Butner looked at him with new eyes. He specially bought Gauss the best arithmetic book from Hamburg, saying, "You have surpassed me, and I have nothing to teach you."
Then, Gauss and Bater's assistant Bater established a sincere friendship until Bater died. They studied together and helped each other, and Gauss began real mathematics research.
Data expansion: story: a literary genre that focuses on the description of the development process of events. It emphasizes the vividness and coherence of the plot and is more suitable for oral narration.
What happened. Or imagine a story.
Stories are generally closely related to the production and life of primitive humans. Primitive humans are eager to understand nature, so they fantasize that everything in the world has life and will be like people. Some stories are a kind of memory behavior of human history, and people use various story forms.
Memorize and spread the cultural traditions and values of a certain society and guide the formation of social character. By recalling and narrating the past, the story describes the cultural form of a certain range of society. It is also said that the story is not a style, but an event, which has a meaning through narration.
He played a great role in studying the spread and distribution of culture in history. Language is dynamic.
Stories don't need too many descriptions of psychological activities, long dialogues, complicated and delicate descriptions of scenery and characterization, and authors should not comment on the characters or events in the stories. The author should always pay attention to promoting the flow and progress of the story.
Language is dynamic, and the characters in it will live without deliberate description. Love stories mainly refer to love stories between men and women, which are recorded in the form of stories and published on the internet or magazines.
Love articles are based on the description of love between men and women, exploring the meaning of love and describing the forms of love. You can use real events as the writing background, and you can also beautify love stories.
