Mathematics is closely related to us in life, and mathematics handwritten newspaper is also closely related to students. The following is the handwritten newspaper of second-grade mathematics that I brought to you. I hope you like it.

Example: 1 The puppy found 1 a running rabbit 8 meters ahead, and immediately caught up with it. It is known that the distance that a puppy runs two steps is equal to the distance that a rabbit runs five steps, but the rabbit runs fast, and the puppy can only run three steps when the rabbit runs five steps. How many meters does the puppy have to run to catch up with the rabbit?

Answer: Speed = Distance/Time

According to the relationship given by the topic:

The pace of two dogs = the pace of five rabbits (1)

3 Dog Walking Time =5 Rabbit Walking Time (2)

Dog's stride = dog's pace = dog's speed.

Rabbit pace = rabbit speed.

So: (1) formula ÷(2) formula is available.

2 speed of dog =3 speed of rabbit.

That is to say, at a certain moment, the dog ran 3 meters and the rabbit ran 2 meters, with a difference of1m.

In order to make them 8 meters apart,

Then the dog runs for 24m and the rabbit runs 16m.

The puppy can run at least 24 meters to catch up with the rabbit.

Mathematical Manuscript II: The Story of Mathematician Sue

A math class in Zhejiang 10 Middle School in Wenzhou led Su to the road to the kingdom of mathematics. Teacher Yang, who returned to Wenzhou from studying in Japan, took a math class with a real feeling of worrying about the country and the people: "In today's world, the law of the jungle prevails. The world powers built cannons by ships, carved up China's beans and wolfed them down. The danger of national subjugation and extinction of the Chinese nation is imminent. In order to save the nation and survive, we must revitalize science. Mathematics is the pioneer of science. In order to develop science, we must learn math well. " Teacher Yang's words touched Sue's heart. Since then, his interest has shifted from literature to mathematics. Once, Sue proved a geometric theorem in 20 different ways. When the headmaster first learned, he called Sue to the office, patted him on the shoulder and said, "Study hard and send you abroad to study in the future." When he graduated from Suzhou University, President Hong had been transferred to the Ministry of Education in Beijing, but he still cared about Su's study and sent 200 yuan money to help Su study abroad.

19 19, 17-year-old Sue bought a boat ticket to Japan, and the rest 170 yuan could hardly support him for three months. He can only eat two meals a day and has no money to hire a Japanese teacher, so he has to learn from the landlord. Finally, he answered the examiner's questions in fluent Japanese, and entered the famous school-tokyo institute of technology Electrical Engineering Department with the first place. 1924 was admitted to the Department of Mathematics of Imperial University in Tohoku, Japan with the first place, and studied under the famous geometer Professor Tadashian. 1927, after graduating from college, I sold newspapers, delivered milk, proofread magazines and tutor after school, and paid tuition with the money I earned, so I was promoted to the graduate school of our school without an exam. With a strong will, he studied hard and published 4 1 research papers on affine differential geometry and projective differential geometry, which opened up a new field of differential geometry research and was called "a brilliant mathematical star rising from the eastern countries" by the mathematical community. 193 1 in March, 2008, he obtained the doctor of science degree with excellent results, becoming the second foreigner to receive this degree after Chen. Since then, invitations from home and abroad have flown in like snowflakes, and Sue refused them one by one. Because two years ago, when Chen got his doctor of science degree, he sent Su to Zhejiang University, where the conditions were very poor. Sue said, "Go home first, and I'll come back after graduation. Let's make the Department of Mathematics of Zhejiang University a world-class department in 20 years ... "This may be the reason why Su did not want to leave Zhejiang University when the departments of colleges and universities in China were adjusted.

After Su took office, except for the quartic (cubic) algebraic cone discovered in graduate school, which was called Su cone in academic circles, he later made brilliant scientific research and teaching achievements in the fields of projective curve theory, projective surface theory, high-dimensional projective space yoke network theory, general spatial differential geometry, computational geometry and so on. He also proved that the closed Laplace sequence and structure (T4) are called "Su (Qing Bu) chain" by the world academic circles. Therefore, the famous German mathematician Brasuke called Su "the first geometer in the East", and mathematicians in Europe, America and Japan called him and his colleagues "Zhejiang University School". Indeed, during the period from 193 1 to 1952, the Soviet Union trained nearly 100 students, of whom 25 served as deans and vice-deans in more than 10 famous universities nationwide, 5 were elected academicians of the Chinese Academy of Sciences, and even 3 academicians trained after liberation. In Fudan University of Mathematics, there are Gu Chaohao, Hu, Hu and Su, which is a rare and gratifying phenomenon.
