The story of a mathematician should not exceed 180 words

When Gauss was in elementary school, once after the teacher taught addition, because the teacher wanted to rest, he came up with a problem for the students to calculate, the topic was: 1+2+3+97+98+99+100 = ?

The teacher was thinking to herself, now the children must be counted as the end of class! I was about to excuse myself when I was about to excuse myself to go out, but I was stopped by Gauss!! It turns out that Gauss has already calculated, do you know how he calculated, kid?

96+97+98+99+100 100+99+98+97+96+ .4+3+2+1 =101+101+101+ .101+101+101+101 adds up a hundred 101s, but the equation is repeated twice, so dividing 10100 by 2 gives the answer equal to <5050> Since then, Gauss's learning process in primary school has already surpassed other students, which has laid the foundation for his future mathematics and made him a mathematical genius!

You can condense it yourself.

When Gauss was in elementary school, once after the teacher taught addition, he wanted to rest, so he came up with a problem for his classmates to calculate: 1+2+3+98+99+100 = ?

The teacher thought to herself, now the children must be counted as the end of class! I was about to excuse myself when I was about to excuse myself to go out, but I was stopped by Gauss!! It turns out that Gauss has already figured it out.

Gauss calculates that 1 to 100 and 100 to 1 are added in two rows, i.e., 1+2+3+4+

96+97+98+99+100 100+99+98+97+96+……4+3+2+1 =101+101+101+101+101+101+101……There are 100 100s added up, but the equation is repeated twice, so dividing 10100 by 2 gives the answer equal to <5050> Since then, Gauss's learning process in primary school has already surpassed other students, which has laid the foundation for his future mathematics and made him a mathematical genius!

One day in 1796, a young man began to work on math problems left by his mentor.

The first two questions were completed smoothly. There is only the third question left: it is required to draw a regular 17-sided shape using only a ruler and a gauge.

The young man racked his brains, but nothing was done.

Difficulties stir up fighting spirit. He finally got the job done.

The tutor was stunned to see the student's assignment. He said excitedly, "You know what? You've solved a math puzzle that's been left over 2,000 years ago! ”

It turned out that the tutor handed the note to the student because of a mistake.

Whenever he recalled, the young man always said, "If someone had told me that this was a mathematical problem that was more than 2,000 years old, I might never have the confidence to solve it." ”

This young man was Gauss, the prince of mathematics.

Hua Luogeng is diligent and talented.

When he was a child, Hua Luogeng's family was poor, and he dropped out of school before graduating from junior high school to help his father take care of a small shop. During the day, Hua Luogeng worked in the small grocery store, stood at the counter, planned the plate, and kept accounts. When I have free time, I bury my head in reading books or arithmetic exercises.

Hua Luogeng's ambition and deeds, he overcame unimaginable difficulties and resistance. Moving forward, on the contrary, tempered him. There is no time, so he has developed the habit of getting up early, being good at using fragmented time, and being good at mental arithmetic.

Without books, he developed the habit of being diligent in his hands and diligent in independent thinking. This habit remained until his later years.

One day, the French mathematician Pu Feng invited many friends to his home and did an experiment. Pu Feng laid out a large white paper on the table, and the white paper was full of parallel lines at equal distances, and he took out many small needles of equal length, and the length of the small needles was half the length of the parallel lines. Pu Feng said:

Please put these little needles on this blank piece of paper and feel free to do so! The guests did as he was told.

This number is an approximation of . An approximation of pi is obtained each time, and the more times you throw, the more accurate the approximation of pi will be. This is known as the "Pufeng Experiment".

Mathematical magician.

One summer day in 1981, a mental arithmetic competition was held in India. The performer is a 37-year-old woman from India whose name is Shaguntana. On that day, she had to compete with an advanced electronic computer with amazing mental arithmetic skills.

The staff writes a large number of 201 digits and asks you to find the 23rd square root of the number. As a result, it took only 50 seconds for Shaguntana to report the correct answer to the audience. In order to arrive at the same number of answers, the computer has to input 20,000 instructions and then calculate them, which takes much more time than Shagontana.

This anecdote caused an international sensation, and Shagontana was called the "mathematical magician".

There are too many typos, and life is a non-stop!

Have you heard the story of Gauss adding from 1 to 100?

I think why not find someone who types very quickly.

One day, when Chen Jingrun was eating lunch, he touched his head, oops, his hair is too long, he should go and get a haircut, otherwise, people will see it and think he is a girl. So, he put down his job and went to the barbershop.

It's my turn to be early. He passed by the foreign language reading room, and there were all kinds of new books, which were very good. He ran in again and read the book, and when he saw the sun go down, he remembered about the haircut.

As soon as he touched his pocket, the small number 38 was still lying well. But what's the use of him coming to the barbershop, this number has long been outdated.

A short story of a famous mathematician.

1.When the mathematician Gauss was in high school, every night the teacher would give him one or two difficult problems for him to practice, but he could basically solve them quickly, but one day, the teacher gave a problem, and he used one night to make it, and then when he came to the school and asked the teacher, he learned that the problem was accidentally caught by the teacher, which is a mathematical problem in the world and has plagued mathematicians for more than 100 years.

2.Or Gauss, in elementary school, in order to punish students, the teacher asked them to calculate 1 until 100, and when everyone else was desperately adding, Gauss quickly calculated it using the method that the number is equal to 101 at the beginning and the end.

Zu Chongzhi (429-500 AD) was a native of Laiyuan County, Hebei Province, during the Northern and Southern Dynasties of China. He read many books on astronomy and mathematics since he was a child, and he was diligent in learning and practicing hard, which finally made him an outstanding mathematician and astronomer in ancient China.

Zu Chongzhi's outstanding achievement in mathematics is about the calculation of pi. Before the Qin and Han dynasties, people to:"Trail three times a week"As pi, this is"Ancient rate"。Later, it was found that the error of the paleorate was too large, and the pi should be"The circle diameter is more than three days", but how much is left, opinions differ.

It was not until the Three Kingdoms period that Liu Hui proposed a scientific method for calculating pi"Circumcision"to approximate the circumference of the circle by incorporating the perimeter of the regular polygon. Liu Hui calculates that the circle is inlaid with 96 polygons, and obtains =, and points out that the more sides of the inscribed regular polygon, the more accurate the value obtained. On the basis of the achievements of his predecessors, Zu Chongzhi has worked hard and repeatedly calculated to find out between and .

And the approximate value in the form of fraction is obtained, which is taken as the approximate rate and taken as the density rate, where six decimal places are taken, which is the fraction with the closest value of the numerator denominator within 1000. What method Zu Chongzhi used to arrive at this result is now impossible to examine. If you imagine that he is according to Liu Hui's"Circumcision"If you want to find this method, you have to calculate that the circle is connected with 16,384 polygons, which requires a lot of time and labor!

It can be seen that his tenacious perseverance and intelligence in academic management are admirable. It was more than a thousand years before foreign mathematicians obtained the same result for Zu Chongzhi's calculation of the density rate. In order to commemorate Zu Chongzhi's outstanding contributions, some foreign historians of mathematics have suggested that = be called"Ancestral rate"。
