The main contents are: easy-to-mistake problem sorting, key content review, example sorting, etc. You can use handwritten newspaper, computer printing, newspaper clippings and other forms. Mathematics tabloid is demanding and difficult, so students had better finish it with their parents. But it can't be a single form. We should apply what we have learned and not blindly and rigidly imitate old-fashioned forms.

Materials for making tabloids:

(1) Mathematical Story

1. Archimedes, an ancient Greek scholar, died at the hands of Roman enemy soldiers who attacked Sicily. ), people carved the figure of the ball in the cylinder on his tombstone to commemorate his discovery that the volume and surface area of the ball are two-thirds of that of the circumscribed cylinder. Galois was born in a town not far from Paris. His father is the principal of this school and has served as the 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. 4./kloc-Rudolph, a German mathematician in the 6th century, spent his whole life calculating pi to 35 decimal places, which was later called Rudolph number. After his death, someone else 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 carved on the tombstone, and the inscription also read: "Although I have changed, I am the same as before." This is a pun, which not only depicts the nature of spiral, but also symbolizes his love for mathematics. Von Neumann is one of the most outstanding mathematicians in the 20th century. As we all know, the electronic computer invented by 1946 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. During his study in Lu Se Lun Middle School in Budapest, Von Neumann got ahead and was highly praised by his teachers. Under Fichte's individual guidance, he co-published his first mathematical paper. At this time, von Neumann was less than 18 years old. 6. Zu Chongzhi's outstanding achievement in mathematics is the calculation of pi. Before Qin and Han Dynasties, people took "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 one week is greater than three weeks", but there were different opinions on how much was left. The circumference of a circle inscribed with a regular polygon is used to approximate the circumference of a circle. 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 7. 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 can be seen that his tenacious perseverance and intelligence in academic research are admirable. Zu Chongzhi's secret rate has been calculated for more than 1000 years, and foreign mathematicians have reached the same result. In order to commemorate Zu Chongzhi's outstanding contribution, some mathematicians abroad suggested that π = be called "ancestral rate". 8. Born in 624 BC, Ju Lushi was the first great 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. 9. The famous German mathematician Gauss has the reputation of "prince of mathematics". When I was a child, Gauss's family was poor, and his father found it useless to study, but Gauss still liked reading. It is said that when he was a child, his father would tell him to go to bed after dinner in winter to save fuel. But when he goes to bed, he will hollow out the inside of the turnip, put it in a cotton roll and use it as a lamp to continue his research. Gauss has a famous story: in a very short time, he calculated the task assigned by the primary school teacher: from 650 to a natural number. The method he used was: sum 50 pairs of sequences constructed as sum101(1+100, 2+99, 3+98 ...) and get the result: 5050. This year, Gauss was 9 years old. 10. Genius comes from accumulation, and cleverness lies in diligence. ——— The Story of China/kloc-0 One day in 930, Xiong Qinglai, head of the Department of Mathematics at Tsinghua University, was sitting in his office reading a science magazine. Looking at it, I can't help but exclaim: "Which country is this China from?" "Which university does he teach at?" Finally, a teacher from Jiangsu said slowly, "My brother has a classmate named Hua who only went to junior high school. Xiong Qinglai was surprised and invited Hua to Tsinghua University. Since then, Hua has become a teaching assistant in the Department of Mathematics of Tsinghua University. The following year, his papers began to be published in famous foreign mathematical magazines. A few years later, Hua was sent to Cambridge University in England to study. His theory was named "Fahrenheit Theorem" by the mathematical community.

(2) Mathematics in life

Learning mathematics should be used in real life. Mathematics is used by people to solve practical problems. In fact, there will be math problems in life. For example, when you go shopping, you will naturally use addition and subtraction, and you always have to draw pictures when you build a house. There are countless problems like this, and this knowledge comes from life and is finally summed up as mathematical knowledge, which solves more practical problems. I once saw a report that a professor asked a group of foreign students, "How many times will the minute hand and the hour hand overlap between 12 and 1?" Those students all took off their watches from their wrists and began to set hands; When the professor tells the same question to the students in China, the students will use mathematical formulas to make calculations. The commentary said that it can be seen that China students' mathematical knowledge is transferred from books to their brains, so they can't use it flexibly. They seldom think of learning and mastering mathematics knowledge in real life. From then on, I began to consciously connect mathematics with daily life. Once, my mother baked a cake, and two cakes could be put in the pot. I thought, isn't this a math problem? It takes two minutes to bake a cake, one minute in front and one minute in the back. At most, two cakes are put in the pot at the same time. How many minutes does it take to bake three cakes at most? I thought about it and came to the conclusion that it takes 3 minutes: first, put the first cake and the second cake into the pot at the same time, 1 minute later, take out the second cake, put the third cake and turn the first cake over; Bake again 1 min, so that the first cake is ready. Take it out. Then put the reverse side of the second cake on it, and turn the third cake upside down at the same time, so it will be all done in 3 minutes. I told my mother about this idea, and she said, actually, it won't be so coincidental. There must be an error, but the algorithm is correct. It seems that we must apply what we have learned in order to make mathematics serve our lives better. Mathematics should be studied in life. Some people say that the knowledge in books has little to do with reality now. This shows that their knowledge transfer ability has not been fully exercised. It is precisely because learning cannot be well understood and applied in daily life that many people do not attach importance to mathematics. I hope that students can learn mathematics in their lives and use mathematics in their lives. Mathematics is inseparable from life. If they study thoroughly, they will naturally find that mathematics is actually very useful.

Professional characteristics Three scientists went to Scotland from London to attend a conference. Soon after crossing the border, they found a black sheep. "This is very interesting," said the astronomer. "All sheep in Scotland are black." "This inference is unreliable," replied the physicist. "We can only conclude that some sheep in Scotland are black." The logician immediately went on to say, "What we really know is that there is at least one black sheep in at least one place in Scotland." According to your algorithm, the number of life and death per minute is balanced, and the number of people on the earth is eternal. But you know, in fact, the population on the earth is growing. To be exact, 1.6749 people are born every minute, which is quite different from the number you provided in your poem. To be realistic, if you don't object, I suggest that you use a score of 7/6, that is, change the poem to: "Every minute, a person dies, and every minute, one and a sixth people are born ..."-... His girlfriend asked him, "Do you really mind my freckles?" The mathematician replied softly, "Absolutely not! I was born to like dealing with decimal points. " -"Mathematicians, of course." "Why?" "They fight for every ounce!" -When his wife came home, he handed her a note that read: "Wipe your tears 1 1 time; Tie shoelaces 15 times; Blow toy balloons for each child five times, and the average life of each balloon is 10 second; Warning children not to cross the road 26 times; The child insisted on crossing the road 26 times; I want to do it again on Saturday. " The old professor travels by train. When the conductor came to check the ticket, he couldn't find it The old professor was sweating with anxiety. The conductor said, forget it, just make up another ticket. Old Professor: How did this happen? I don't know where I'm going until I find that ticket! But you can still learn a thing or two from his tombstone, which tells people all the year round that he is 84 years old. The tombstone of Diao Fandu is like this: Diao Fandu was buried here. If you understand the mystery of the inscription, it will tell you the life of the diaojiao building. The gods gave him 1/6 of life as his childhood. After112 of life, he grew a beard, and then Diao Fan got married, but he had no children, so he spent 1/7 of life. Five years later, he had his first son, but his beloved son died young. Hilbert, a famous mathematician at that time, admired Amy's talent very much. He ran around asking for permission to be the first female lecturer at the University of G? ttingen, but there was still controversy at the professor meeting. A professor said excitedly, "How can a woman be a lecturer?" If she is allowed to be a lecturer, she will become a professor in the future and even enter the university Council. Can women be allowed to enter the highest academic institutions of universities? "Another professor said," When our soldiers came back from the battlefield and found themselves prostrating themselves at the feet of women, how did they feel? "Hilbert stood up and resolutely refuted:" Gentlemen, the gender of the candidate should never be an argument against her becoming a lecturer. After all, the university Council is not a bathhouse! "-.It is said that you have a deep understanding of mineralogy and are proficient in botany. ""Yes, I like botany very much, "Lobachevsky replied. "When I get married in the future, I will definitely build a greenhouse ..." "Then get married quickly." "But contrary to my wish, my interest in botany and mineralogy has made me a bachelor all my life." The manager asked him, "How much salary do you ask for a year?" With my working ability, my annual salary should be 18000 yuan. "Chen Liyan said. The manager looked at him for a while and then said, "Is it worth 18 thousand a year?" Is it clear? There are only 365 days in a year. If you sleep eight hours a day, a year is 122 days. 365 days minus 12 1 day. Furthermore, you have eight hours of rest and entertainment besides going to work in the mountains every day, which means 122 days a year. Then subtract 12 1 day from 243 days, leaving only 12 1 day. But there are 52 weeks in a week, and there is no work on Sundays, so 12 1 day subtracts 52 days to leave 69 days. At the same time, every Saturday afternoon is a holiday, so there are 26 days in a year, so 69 days MINUS 26 days leaves 43 days. Minus the two-week annual leave given by the company, there are only 29 days left. Don't forget to have an hour's lunch every day, which means 15 days a year. 29 MINUS 15, leaving 14 days. Excluding public holidays such as the new calendar year, the old calendar year, Mid-Autumn Festival, Easter, Thanksgiving, Christmas *** 10, that is to say, I only work four days a year. Do you think it's worth 18 thousand yuan? Guo Wen is a great man, but he is a heavy drinker, and every time he drinks, the whole bottle is unhappy. One day, he was half drunk again. His wife complained that he drank the whole bottle of wine. Hearing this, Guo opened his eyes slightly, picked up the empty bottle in one hand and shook his head. "Pessimists think half a bottle of wine is half empty, optimists think half a bottle of wine is full." Whether pessimistic or optimistic, it will always be-1/2 full bottle of wine = 1/2 empty bottle of wine. However, there are clouds in the laws of algebra. Both sides of the equation are multiplied by the same constant, and its value remains the same. Then, multiply 2 to get-1 full bottle of wine = 1 empty bottle of wine. So didn't you say I just drank a full bottle of wine and didn't drink it at all? 」 -

(4) Interesting mathematical problems

1. Two boys each ride a bicycle, starting from two places 20 miles apart (1 mile +0.6093 km) and riding in a straight line. At the moment they set off, a fly on the handlebar of one bicycle began to fly straight to another bicycle. As soon as it touched the handlebar of another bicycle, it immediately turned around and flew back. The fly flew back and forth, between the handlebars of two bicycles, until the two bicycles met. If every bicycle runs at a constant speed of 10 miles per hour and flies fly at a constant speed of 15 miles per hour, how many miles will flies fly? The speed of each bicycle is 10 miles per hour, and the two will meet at the midpoint of the distance of 2O miles after 1 hour. The speed of a fly is 15 miles per hour, so in 1 hour, it always flies 15 miles. Many people try to solve this problem in a complicated way. They calculate the first distance between the handlebars of two bicycles, then return the distance, and so on, and calculate those shorter and shorter distances. But this will involve the so-called infinite series summation, which is very complicated advanced mathematics. It is said that at a cocktail party, someone asked John? John von neumann (1903 ~ 1957) is one of the greatest mathematicians in the 20th century. ) Put forward this question, he thought for a moment, and then gave the correct answer. The questioner seems a little depressed. He explained that most mathematicians always ignore the simple method to solve this problem and adopt the complex method of summation of infinite series. Von Neumann had a surprised look on his face. "However, I use the method of summation of infinite series," he explained.
