2. The story of mathematicians PPT

Interesting story of mathematics:

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.

3. A short story about the first three minutes of math class

Earlier, there were two great French mathematicians, one named bhaskar and the other named Fermat.

Pascal knew two gamblers and they asked him a question. They said that after they made a bet, it was agreed that whoever won the first five games would get all the bets. Gambling for a long time,

A won four games,

B won three games, too late. They don't want to gamble anymore. So, how should this money be divided?

Do you divide the money into seven parts, four for those who win four games and three for those who win three games? Or because the first time I said five innings, no one arrived, so one person got half?

Neither of these points is correct. The correct answer is: the person who wins four games gets 3/4 of the money, and the person who wins three games gets 1/4 of the money.

Why? Suppose the two of them gamble again, or

A wins, or

B won. if

A won five games and all the money should go to him;

If you lose, it is.

A:

B Win four games each, and share the money equally. at present

The probability of winning or losing is 1/2, so the money he takes should be1/2 *1+1/2 *1/2 = 3/4. of course，

B should get 1/4.

Through this discussion, an important concept in probability theory-mathematical expectation began to take shape.

Among the above problems, mathematical expectation is an average, that is, how to calculate the uncertain money in today's future is necessary.

The probability of winning or losing is 1/2. Multiply the money he may get and add them up.

Probability theory has developed since then, and today it has become a very widely used subject.

5. How to write a short math story?

1, interesting math story

Thales saw that people were reading the notice, so he went to check it. The initial notice said that Pharaoh wanted the smartest person in the world to measure the height of the pyramid. So I went to Pharaoh.

Pharaoh asked Thales what tools he used to measure the pyramids. Thales said he only used a stick and a ruler. He put the stick next to the pyramid. When the shadow of the stick was as long as the stick, he measured the length of the shadow of the pyramid and half the length of the bottom of the pyramid. Add these two lengths to get the height of the pyramid. Thales is really the smartest man in the world. He can easily measure the height of the pyramid without climbing to the top.

2. Interesting math story

During the Warring States Period, Qi Weiwang and Tian Ji raced, and Qi Weiwang and Tian Ji each had three good horses: getting on, winning and dismounting. The race is divided into three times, and thousands of dollars are bet on each horse race. Because the horsepower of the two horses is almost the same, and Qi Weiwang's horse is better than Tian Ji's, most people think that Tian Ji will lose.

However, Tian Ji took the advice of his disciple Sun Bin (a famous strategist) and dismounted Qi Weiwang's horse, Ma Zhong of Qi Weiwang and Qi Weiwang. As a result, Tian Ji beat Qi Weiwang 2-/kloc-0-and won a lot of money. This is an example of China's ancient substitution game theory to solve problems.

3. Interesting math story

The animal school held a children's song competition, with the elephant teacher as the referee.

The little monkey raised his hand first and began to recite: "I can calculate carry addition, and the digits can only be added if they are aligned." The number of digits should be aligned with the number of digits. When the number of digits exceeds ten, the number of digits should be advanced to ten. Add ten and one to count quickly and accurately. "

As soon as the little monkey finished speaking, the puppy began to recite again: "abdication and subtraction are not difficult, just align the numbers." If the single digits are small enough, ten people can borrow one. If ten people return, one will be ten, and if they return, one will be missing. How to reduce ten digits, ten digits will be reduced again and again. "

Everyone applauded their wonderful performance. Teacher Elephant said, "Their nursery rhymes make us understand that both carry addition and abdication subtraction should win the championship, ok?" Everyone agrees and applauds them.

6. Ask a few mathematicians for interesting stories, not too short or too long (about 3 or 4 crosses).

1, unfair

"Teacher, I found something wrong with the probability formula!"

"oh? Tell me your reasons. "

"There are 50 students in our class. According to the calculation, the probability of being asked is 2%, but today you almost let this course.

I answered all the questions. "

2. Possibility

I visited the weather station and saw many latest weather forecasting instruments. After the visit, I asked the stationmaster, "You said there were hundreds."

How is the 75th probability calculated when it rains? "

Without much thought, the stationmaster replied, "That is to say, there are four people here, and three of them think it will rain."

3. Negative numbers

Mathematicians, biologists and physicists sat in street cafes and watched people walk into a house across the street.

Get out. They first saw two people go in, and after a long time, they saw three people come out. Physicist: "Do you measure?"

Accurate enough. Biologist: "They reproduce." Mathematician: "If one more person goes in now, then the house."

It will be empty. "

4. Statisticians

Mathematics consists of 50% formula, 50% proof and 50% imagination. Topologists can't tell coffee cups from bagels.

The head of the statistician will say, "It feels good on average."

5, the height of the flagpole

A team of engineers are measuring the height of the flagpole. They only have a tape measure, which is difficult to fix on the flagpole because of the leather.

Rulers always fall. A mathematician passed by and pulled out the flagpole, so it was easy to measure the data. After he left, an engineer

The teacher said to the other, "Mathematicians always do this." We asked for height, but he gave us length! " "

6. What is π?

Mathematician: π is the ratio of circumference to diameter. Engineer: π is about 22/7. Computer Programmer: Under double precision

π is 3. 14 159653589. Nutritionist: You die-hard math brains, the "pie" is delicious and healthy.

7. Ask the mathematician to tell a short story.

Buffon Experiment One day, French mathematician Buffon invited many friends to his home and did an experiment. Buffon spread a big piece of white paper on the table, which was covered with parallel lines with equal distance. He also took out many small needles of equal length, the length of which was half that of parallel lines. Buffon said, "Please feel free to leave these small needles on this piece of white paper!" " The guests did as he said.

Buffon's statistics show that everyone voted 22 12 times, of which the small needle crossed the paper parallel line 704 times, and 2210 ≈ 704 ≈ 3.142. Buffon said, "This number is an approximation of π.

You will get an approximate value of pi every time. The more times you throw it, the more accurate the approximate value of pi will be. "This is the famous Buffon experiment.

Von Neumann, one of the most outstanding mathematicians in the 20th century. As we all know, the electronic computer invented by 1946 has greatly promoted the progress of science and technology and social life. In view of von Neumann's key role in the invention of electronic computers, he is called "the father of computers" by westerners. From 19 1 1 to 192 1, von Neumann got ahead when he was studying in Lu Se Lun Middle School in Budapest, and was highly valued by teachers. Under the individual guidance of Mr. Fichte, von Neumann published his first mathematical paper in cooperation.

Galois was born in a town not far from Paris. His father is the headmaster of the school and has served as mayor for many years. The influence of family makes Galois always brave and fearless. 1823, 12-year-old galois left his parents to study in Paris. Not content with boring classroom indoctrination, he went to find the most difficult mathematics original research by himself. Some teachers also helped him a lot. Teachers' evaluation of him is "only suitable for working in the frontier field of mathematics".

Archimedes was born in Syracuse, Sicily, at the southern tip of the Italian peninsula in 287 BC. Father is a mathematician and astronomer. Archimedes had a good family upbringing since childhood. 1 1 years old, was sent to study in Alexandria, the cultural center of Greece. In this famous city known as the "Capital of Wisdom", Archimedes Job collected books and learned a lot of knowledge, and became a protege of Euclid students erato Sese and Cannon, studying geometric elements.

Zu Chongzhi's outstanding achievement in mathematics is about the calculation of pi. Before the Qin and Han Dynasties, people used "the diameter of three weeks a week" as pi, which was called "Gubi". Later, it was found that the error of Gubi was too large, and the pi should be "the diameter of a circle is greater than the diameter of three weeks". However, there are different opinions on how much is left. Until the Three Kingdoms period, Liu Hui put forward a scientific method to calculate pi-"secant" which approximated the circumference of a circle with the circumference inscribed by a regular polygon. Liu Hui calculated the circle inscribed with a 96-sided polygon and got π=3. 14, and pointed out that the more sides inscribed with a regular polygon, the more accurate the π value obtained. On the basis of predecessors' achievements, Zu Chongzhi devoted himself to research and repeated calculations. It is found that π is between 3. 14 15926 and 3. 14 15927, and the approximate value in the form of π fraction is obtained as the reduction rate and density rate, where the six decimal places are 3. 14 1929. There's no way to check now. If he tries to find it according to Liu Hui's secant method, he must work out 16384 polygons inscribed in the circle. How much time and labor it takes! It is obvious that his perseverance and wisdom in academic research are admirable. It has been more than 1000 years since foreign mathematicians obtained the same result in the secrecy rate calculated by Zu Chongzhi. In order to commemorate Zu Chongzhi's outstanding contribution, some mathematicians abroad suggested that π = be called "ancestral rate".

Born in 624 BC, Ju Lushi was the first famous mathematician in ancient Greece. He used to be a shrewd businessman. After he accumulated considerable wealth by selling olive oil, Cyrus devoted himself to scientific research and travel. He is diligent and studious, at the same time, he is not superstitious about the ancients, and he is brave in exploration, creation and positive thinking. His hometown is not too far from Egypt, so he often travels to Egypt. There, Ju Lushi learned about the rich mathematical knowledge accumulated by ancient Egyptians for thousands of years. When he traveled in Egypt, he calculated the height of the pyramids in a clever way, which made the ancient Egyptian king Amerasis admire him very much.
