You can write some stories about mathematicians and common sense about applied problems.

■ Resume:

1933 was born in Minhou, Fujian on May 22nd. Born in poverty, he studied hard and had a soft spot for mathematics when he was in primary and secondary schools. He did exercises whenever he had time and became a "little math fan" at school. He is inarticulate, sincere and kind, never cares about personal gains and losses, and has devoted his life experience to the cause of mathematics. Without graduating from high school, he was admitted to Xiamen University with the same academic qualifications. 1953 graduated from the Mathematics Department of Xiamen University. From 65438 to 0957, he entered the Institute of Mathematics of China Academy of Sciences and studied number theory under the guidance of Professor Hua. He has been a researcher at the Institute of Mathematics of China Academy of Sciences, a member of the academic committee, a professor at Guiyang University for Nationalities, Henan University, Qingdao University, Huazhong University of Science and Technology and Fujian Normal University, a member of the Mathematics Discipline Group of the State Science and Technology Commission, and the editor-in-chief of Mathematics Quarterly. Mainly engaged in the research of analytic number theory, and achieved international leading results in the research of Goldbach conjecture. This achievement is called "Chen Theorem" internationally and is widely cited.

■ Main results:

1On June 7th, 742, German mathematician Goldbach put forward an unproven mathematical conjecture that "any even number can represent the sum of two prime numbers", abbreviated as "1+ 1". This conjecture is called Goldbach conjecture. China people opened the door of Goldbach's conjecture with new methods and won the championship, which attracted worldwide attention. This man is the first person in the world to conquer Goldbach's conjecture-Chen Jingrun.

Chen Jingrun not only overcame this problem, but also deeply studied and discussed the relationship between combinatorial mathematics and modern economic management, cutting-edge science and technology and human beings. He has published more than 70 scientific papers in newspapers and periodicals at home and abroad, and has written books such as Interesting Talks on Mathematics and Combinatorial Mathematics.

Chen Jingrun has made many great achievements in the research field of analytic number theory, and won the first prize of National Natural Science Award, Heli Fund Award, China Mathematics Award and many other awards. He is a deputy to the Fourth, Fifth and Sixth National People's Congress. He is the author of Anecdotes in Mathematics and Combinatorial Mathematics.

■ The Fall of Superstars:

1On April 27th, 984, Chen Jingrun was knocked down by a speeding bicycle while crossing the road, and his head landed, seriously injured. To make matters worse, Chen Jingrun, who was already in poor health, suffered almost fatal trauma. He came out of the hospital, his pale face was sometimes blue-gray, and before long, he finally induced Parkinson's syndrome.

1March, 996 19, the famous mathematician Chen Jingrun was hospitalized for a long time due to illness and died at the age of 63 after being rescued.

This belongs to the mathematician Chen Jingrun. You can choose one of them.

2. The content of mathematical handwritten newspaper.

Russell, the first famous saying about mathematics, said, "Mathematics is symbol plus logic." Pythagoras said, "Numbers dominate the universe." Halmos said, "Mathematics is a clever art" and Misra said, "Mathematics is the highest achievement of human thinking." Bacon (English philosopher) said, "Mathematics is the key to science." Bourbaki School (French Mathematics Research Group) believes that "mathematics is abstract knowledge. Mathematics is the symbol of God's description of nature "Oscar Wilde (president of the American Mathematical Society) said:" Mathematics is a culture that will continue to evolve "Plato said:" Mathematics is the highest form of all knowledge "Courte said:" Mathematics is the brightest pearl in the crown of human wisdom "The second book on the significance of mathematics, as an expression of human thinking, reflects people's active will, meticulous logical reasoning and pursuit of perfection.

Its basic elements are: logic and intuition, analysis and reasoning, generality and individuality. Although different traditional schools can emphasize different aspects, it is the interaction of these opposing forces and their comprehensive efforts that constitute the vitality, availability and lofty value of mathematical science.

Third, write a short story about mathematics-a short story about a famous mathematician-Cantor often draws some logical but absurd results (called "paradox") when he studies infinity, and many great mathematicians take an evasive attitude for fear of falling into it. During the period of 1874- 1876, Cantor, a young German mathematician less than 30 years old, declared war on the mysterious infinity.

With hard sweat, he successfully proved that points on a straight line can correspond to points on a plane one by one, and can also correspond to points in space one by one. In this way, it seems that there are "as many" points on the 1 cm long line segment as there are points in the Pacific Ocean and the whole earth. In the following years, Cantor published a series of articles about this kind of "infinite * * *" problem, and drew many amazing conclusions through strict proof.

Cantor's creative work has formed a sharp conflict with the traditional mathematical concept, which has been opposed, attacked and even abused by some people. Some people say that Cantor's theory of * * * is a kind of "disease", Cantor's concept is "fog in fog", and even Cantor is a "madman".

Great mental pressure from the authority of mathematics finally destroyed Cantor, making him exhausted, suffering from schizophrenia and being sent to a mental hospital. True gold is not afraid of fire, and Cantor's thought finally shines.

At the first international congress of mathematicians held in 1897, his achievements were recognized, and Russell, a great philosopher and mathematician, praised Cantor's work as "probably the greatest work that can be boasted in this era." But at this time, Cantor was still in a trance, unable to get comfort and joy from people's reverence.

1918 65438+1October 6th, Cantor died in a mental hospital. Finally, I can write a joke about mathematics. When I came back, my mother asked him how he did in the math exam. Xiao Ming said: "I can basically do it, but I can't do a problem of 3 times 7." Finally, the bell rang, so I wrote a 18 regardless of the willy-nilly.

3. How to do math handwritten newspaper is very simple.

Methods/steps

1

Generally speaking, the paper used to make handwritten newspapers is sketch paper.

Sketch paper can be bought at stationery stores. The commonly used size is 4 quarts or 8 quarts. However, the 4-quart handwritten newspaper is too big, which will bring great difficulty to the production of handwritten newspaper.

By contrast, the 8-carat one is just 16 carat, which is too small. It is recommended to buy 8 carats of sketch paper. If the quality is a little better, you can start doing it.

2

The first trick is to add edges.

Anyone who has experience in making handwritten newspapers knows that we have to work hard on an 8-inch sketch paper for a long time. Many times, after a handwritten newspaper is written, the edge of the sketch paper has been deformed. The solution to this problem is to add edges.

My primary school teacher suggested adding two centimeters. I think it's too wide after trying it. Eight millimeters is enough. And this width can be measured with a common tape measure. If ordinary tape is tied to the edge of sketch paper, it will greatly protect your sketch paper. And after the completion of the whole handwritten newspaper, it will make the handwritten newspaper look very refreshing and tidy.

three

Generally speaking, making a handwritten newspaper, whether it is a mathematical handwritten newspaper or a Chinese handwritten newspaper, requires the producer to consult relevant books and materials as the content of the handwritten newspaper.

A little advice, don't choose too long stories. In the present books, all the words we can see are very small, so let's copy them by hand, which will appear many and long. I was sad when I accidentally chose a long story.

four

After consulting the materials, we will start typesetting. This step can be alternated with the previous step.

After all, when typesetting, we will find that some stories are too long, some stories are too short, or after replacement, there will be better results. Two steps, coordinate with each other, and finally determine the approximate typesetting.

If you want to make a mathematical handwritten newspaper, you can choose the origin of some mathematical patterns, mathematicians' short stories, famous sayings about mathematics, jokes about mathematics and so on.

At this time, typesetting can be done on draft paper!

five

When you start writing handwritten newspapers, don't use indelible pens or signature pens at the beginning, and don't use colored lead or oil pastels.

The best choice is to draw a rough outline with a pencil, make clear what each part of the sketch paper should write, and then add various separation lines, such as straight lines, wavy lines, dotted lines, S-shaped lines and so on. Then add some scrolls such as lace, small patterns or text boxes to the rough separation line.

In a text box that needs to be filled with text, you can choose to use a pencil ruler to check the grid. The width of the grid is determined by the producer, but the width of the same story should be similar. If you don't want to write so many words, just write bigger words and draw wider squares.

The above content is best done with a pencil.

six

The next step is to add text content.

Because all the previous work was done with a pencil, once you have the outline of a pencil, you can write on it with an indelible pen or signature pen.

The same handwritten newspaper can have words written with pens of different colors. For example, you can choose to use a black pen in the upper left corner and a blue pen in the lower right corner. The colors of adjacent plates should also be different. Unless the whole layout has a special meaning.

But one thing to be reminded is, don't write on it with a red pen. Because in any way, handwritten newspapers made with red pens are very inappropriate.

seven

Just after copying the text, the pattern of the handwritten newspaper has been decided, and the rest is revised. Decorative steps, it is recommended to use colored lead and colored pen.

After all, gouache and oil painting, which are used to make handwritten newspapers, are really beyond the reach of ordinary people. If you only use a monotonous black pen, it will probably appear depressing. If you sketch with a pencil, this handwritten newspaper is easy to blur.

eight

Erase the original pencil traces bit by bit, and then replace them with ink pens and colored pencils to draw elaborate patterns.

You must erase the pencil marks before you can draw with colored pens, otherwise the paper will be dirty.

In some inconspicuous places, if you need to draw more fresh and bright, you can use red, blue or black ink pens, which is actually enough.

Do you remember the horizontal lines at the bottom of our words? You can choose to redraw those horizontal lines with a pen, or you can choose to erase them all. If you draw them all and then erase the pencil marks with an eraser, you will get unexpected and wonderful results!

nine

Remember to make appropriate adjustments after the completion of the whole handwritten newspaper, which will make your handwritten newspaper look more beautiful.

These adjustments include: correcting typos, erasing redundant pencil lines, adding some small illustrations, filling blank and abrupt places, and carefully drawing separation lines.

By the way, write your name and production date in the lower right corner. Look at it later. Very memorable!

The development history of ancient mathematics in China, commonly known as arithmetic, is an important subject in ancient science in China. According to the characteristics of the development of ancient mathematics in China, it can be divided into five periods: the germination period; The formation of the system; Development; Prosperity and the integration of Chinese and western mathematics.

At the end of primitive commune, after the germination of ancient mathematics in China, private ownership and commodity exchange appeared, the concepts of number and shape were further developed. The pottery unearthed during Yangshao culture period has been engraved with the symbol representing 1234. By the end of the primitive commune, written symbols had begun to replace knotted notes.

Pottery unearthed in Xi 'an Banpo has an equilateral triangle composed of 1~8 dots, and a pattern of 100 small squares divided into squares. The houses in Banpo site are all round and square. In order to draw circles and determine straightness, people have also created drawing and measuring tools such as rulers, moments, rulers and ropes.

According to Records of Historical Records Xia Benji, Yu Xia used these tools in water conservancy. In the middle of Shang Dynasty, a set of decimal numbers and notation had been produced in Oracle Bone Inscriptions, the largest of which was 30 thousand; At the same time, the Yin people recorded the date of 60 days with 60 names, including Jiazi, Yechou, Bingyin and Dingmao, which were composed of ten heavenly stems and twelve earthly branches. In the Zhou Dynasty, eight kinds of things were previously represented by eight diagrams composed of yin and yang symbols, which developed into sixty-four hexagrams, representing sixty-four kinds of things.

The book Parallel Computation in 1 century BC mentioned the methods of using moments of high, deep, wide and distance in the early Western Zhou Dynasty, and listed some examples, such as hook three, strand four, chord five and ring moments can be circles. It is mentioned in the Book of Rites that the aristocratic children of the Western Zhou Dynasty have to learn numbers and counting methods since they were nine years old, and they have to be trained in rites and music, shooting, controlling, writing and counting. As one of the "six arts", number has begun to become a special course.

During the Spring and Autumn Period and the Warring States Period, calculation has been widely used and decimal notation has been used, which is of epoch-making significance to the development of mathematics in the world. During this period, econometrics was widely used in production, and mathematics was improved accordingly.

The contention of a hundred schools of thought in the Warring States period also promoted the development of mathematics, especially the dispute of rectifying the name and some propositions were directly related to mathematics. Famous experts believe that the abstract concepts of nouns are different from their original entities. They put forward that "if the moment is not square, the rules cannot be round", and defined "freshman" (infinity) as "nothing beyond the maximum" and "junior" (infinitesimal) as "nothing within the minimum".

He also put forward the idea that "one foot is worth half a day, which is inexhaustible". Mohism believes that names come from things, and names can reflect things from different sides and depths.

Mohist school gave some mathematical definitions. Such as circle, square, flat, straight, sub (tangent), end (point) and so on.

Mohism disagreed with the proposition of "one foot" and put forward the proposition of "non-half" to refute: if a line segment is divided into two halves indefinitely, there will be a non-half, which is a point. The famous scholar's proposition discusses that a finite length can be divided into an infinite sequence, while the Mohist proposition points out the changes and results of this infinite division.

The discussion on the definition and proposition of mathematics by famous scholars and Mohists is of great significance to the development of China's ancient mathematical theory. The formation of China's ancient mathematical system The Qin and Han Dynasties were the rising period of feudal society, with rapid economic and cultural development.

The ancient mathematical system of China was formed in this period, and its main symbol was that arithmetic became a specialized subject, and the emergence of mathematical works represented by Nine Chapters of Arithmetic. Nine Chapters Arithmetic is a summary of the development of mathematics during the establishment and consolidation of feudal society in the Warring States, Qin and Han Dynasties. As far as its mathematical achievements are concerned, it is a world-famous mathematical work.

For example, the operation of quartering, the present skills (called the three-rate method in the west), square roots and square roots (including the numerical solution of quadratic equations), the skills of surplus and deficiency (called the double solution in the west), various formulas of area and volume, the solution of linear equations, the principle of addition and subtraction of positive and negative numbers, the Pythagorean solution (especially the Pythagorean theorem and the method of finding Pythagorean numbers) and so on are all very high levels. Among them, the solution of equations and the addition and subtraction of positive and negative numbers are far ahead in the development of mathematics in the world.

As far as its characteristics are concerned, it forms an independent system centered on calculation, which is completely different from ancient Greek mathematics. "Nine Chapters Arithmetic" has several remarkable characteristics: it adopts the form of mathematical problem sets divided into chapters according to categories; Formulas are all developed from counting method; Mainly arithmetic and algebra, rarely involving graphic properties; Attach importance to application and lack of theoretical explanation.

These characteristics are closely related to the social conditions and academic thoughts at that time. In Qin and Han dynasties, all science and technology should serve the establishment and consolidation of feudal system and the development of social production at that time, emphasizing the application of mathematics.

Nine Chapters of Arithmetic, which was finally written in the early years of the Eastern Han Dynasty, ruled out the discussion of famous scholars and Mohists in the Warring States period on the definition and logic of nouns, but focused on mathematical problems and their solutions closely combined with production and life at that time, which was completely consistent with the development of society at that time. Nine Chapters Arithmetic spread to Korea and Japan in Sui and Tang Dynasties, and became the mathematics textbook of these countries at that time.

Some of its achievements, such as decimal numerical system, modern skills and surplus skills, have also spread to India and * * *, and through India and * * * to Europe, which has promoted the development of world mathematics. The development of ancient mathematics in China and the appearance of metaphysics in Wei and Jin Dynasties were not bound by Confucian classics, and their thoughts were more active. It can argue and win, use logical thinking and analyze truth, all of which are conducive to improving mathematics theoretically.

During this period, the Nine Chapters Heavy Difference Diagram appeared in Wu and Zhao's annotation of Zhou Huishu, Xu Yue's annotation of Nine Chapters Arithmetic in the late Han Dynasty and early Wei Dynasty, and Liu Hui's annotation of Nine Chapters Arithmetic in the Wei and Jin Dynasties. The work of Zhao Shuang and Liu Hui laid a theoretical foundation for the ancient mathematical system of China.

Zhao Shuang was one of the earliest mathematicians who proved and deduced mathematical theorems and formulas in ancient China. The Pythagorean Grid Diagram and Annotation and the Daily Height Diagram and Annotation, which he supplemented in Zhou Pian Shu Jing, are very important mathematical documents.

In Pythagorean Square Diagram and Notes, he put forward five formulas to prove Pythagorean theorem and Pythagorean shape with chord diagram; In Sunrise Picture, he proved the weight difference formula widely used in the Han Dynasty with the graphic area, and Zhao Shuang's work was open.
