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. The following is a summary of the contents of the mathematical electronic tabloid, hoping to help you ~
Content 1: Li Ruzhen, a native of Qing Dynasty, was a talented person who learned everything. Maybe he read too much, so he is not satisfied with officialdom. He has written several books, among which "Jing Hua Yuan" is the most widely circulated. This book describes a talented woman who is proficient in arithmetic, "Flower Fairy of Los Angeles". Her name is Milan Finn.
Milanfen and other sisters met in Zongbofu and went to Xiao 'ao Mountain to see the lights. There are two kinds of lights upstairs, one is the three big balls above and six small balls below, and the other is the 18 ball below the three big balls above. There are two kinds of lights downstairs, one is 1 big ball with two small balls, and the other is 1 big ball with four small balls. It is known that there are 396 large light balls upstairs, 1440 small light balls, 360 large light balls downstairs and 1200 small light balls.
How many kinds of four kinds of lights are there upstairs and downstairs? Students, can you work it out?
Mathematics electronic tabloid content 2: mathematics short 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.
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.
Ju Lushi was born in 624 BC. He 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.
4. Zu Chongzhi's outstanding achievement in mathematics is about the calculation of pi. Before the Qin and Han Dynasties, people took "diameter of one week and three weeks" as pi, which was called "Gubi". Later, it was found that the error of Gubi was too big, and the pi should be "more than three times a week". 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 method", which approximated the circumference of a circle with the circumference of a regular polygon. The more sides inscribed in a regular polygon, the more accurate the π value will be. On the basis of predecessors' achievements, Zu Chongzhi worked hard and calculated repeatedly, and found that π was between 3. 14 15926 and 3. 14 15927. He also got an approximation in the form of π fraction as the reduction rate and density rate. Among them, taking six digits after the decimal point is 3. 14 1929, which is the closest fraction to π in 1000. It is impossible to prove how Zu Chongzhi got this result. If he tries to find it according to Liu Hui's secant method, he must work out 16384 edges in the circle. 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".
Galois was born in a town not far from Paris. His father is the headmaster of the school, and he has been 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".
6./kloc-Rudolph, a German mathematician in the 0 th and 6 th centuries, spent his 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 describes the spiral nature, but also symbolizes his love for mathematics.
7. 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.
8. 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.
9. Genius comes from accumulation, and cleverness lies in diligence. ————————— China
The story of flowers
1930 One day, Xiong Qinglai, head of the Department of Mathematics at Tsinghua University, was sitting in his office reading a magazine Science. 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.
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.
