2. 400-word story of a famous mathematician for grade 5

Hua Luogeng

Once, he went out to play in the city with his neighbor’s children. ;Suddenly I saw a deserted tomb beside the road. There were many stone people and horses beside the tomb. This immediately aroused Hua Luogeng's curiosity, and he really wanted to see what happened. So he said to the neighbor's child:

"There may be something fun over there, let's go and have a look, okay?"

The neighbor's child replied: "Okay. But I can only stay for a while, I'm a little scared."

The bold Hua Luogeng said with a smile: "Don't be afraid, there are no ghosts in the world." After saying that, he ran towards the deserted grave first.

The two children came to the grave and looked at the stone men and horses carefully. They touched here and there with their hands. They found it very interesting. Hua Luogeng, who loves to use his brain, suddenly asked the neighbor's child: "How much do these stone people and horses weigh?"

The neighbor's child looked at him in confusion and said, "How can I know? You Why would you ask such a stupid question? No wonder people call you 'Luo Duzi'."

Hua Luogeng said reluctantly: "Can you think of a way to calculate it?"

The neighbor's child laughed when he heard this and said, "You can think about this problem when you become a mathematician in the future! But if you can become a mathematician, I'm afraid it will be a success."

Hua Luogeng ignored the ridicule of the children next door and said firmly: "I will definitely be able to find a way in the future."

Of course, calculating the weight of these stone men and horses , for Hua Luogeng, who later became a mathematician, it was no problem at all.

3. Mathematics Stories for Grade 5

1. Gaussian Series Children, do you know the story of the mathematical genius Gauss when he was a child? When Gauss was in the second grade of elementary school, the teacher once wanted to take a break after teaching addition, so he asked the students to do the math. The question was: 1 2 3 4... 96 97 98 99 100=? I thought the students They were bound to be quiet for a while, and when they were about to find an excuse to go out, they were stopped by Gauss! It turns out that Gauss has already calculated it. Children, do you know how he calculated it? Gauss told everyone how he calculated it: add 1 to 100 and 100 to 1; line up in two rows and want to add, that is: 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 one hundred 101s, but the calculation is repeated twice, so divide 10100 by 2 to get the answer equal to 5050. From then on, Gauss's learning process in elementary school has already surpassed that of other students, which laid the foundation for his future mathematics and made him a mathematical genius.

2. Chicken and rabbit in the same cage Have you ever heard of the problem of "chicken and rabbit in the same cage"? This question is one of the famous interesting questions in ancient my country. About 1,500 years ago, "Sun Zi Suan Jing" recorded this interesting question. The book narrates this: "Today there are chickens and rabbits in the same cage. There are thirty-five heads on top and ninety-four legs on the bottom. How many chickens and rabbits are there? The meaning of these four sentences is: How many chickens and rabbits are there in the same cage? There are 35 heads in a cage and 94 legs in the cage. Can you answer this question? Is there an answer to this question? The answer is this: If you cut off half of the legs of each chicken and rabbit, then each chicken will become a "one-horned chicken" and each rabbit will become a "two-legged chicken". rabbit".

In this way, (1) the total number of chicken and rabbit feet changes from 94 to 47; (2) if there is a rabbit in the cage, the total number of feet is 1 more than the total number of heads. Therefore, the difference between the total number of legs, 47, and the total number of heads, 35, is the number of rabbits, that is, 47-35 = 12 (rabbits). Obviously, the number of chickens is 35-12=23 (birds). This idea is novel and unique, and its "foot-cutting method" has also amazed mathematicians at home and abroad, both ancient and modern. This way of thinking is called reduction. The reduction method means that when solving a problem, we do not directly analyze the problem first, but deform and transform the conditions or problems in the problem until it is finally classified as a solved problem.

3. A short story about outstanding mathematics: The door opened and a young man came in. Mr. Liu Jianming asked him to sit down. The young man introduced himself and said: "I am a tour guide from the Mainland. My name is Yu Jiang. This time I led a tour group to Hong Kong. I heard that your hotel has a comfortable environment and considerate service. We would like to Stay in your hotel." Mr. Liu Jianming said enthusiastically: "Welcome, welcome, welcome. How many people are there in your group?" "It's okay, it's a big group." Mr. Liu Jianming was pleasantly surprised: A big group, another big deal, it’s great. As a tour guide, Yu Jiang could see what Mr. Liu Jianming was thinking. He took it to heart and said slowly: "Sir, if you can calculate the number of people in our group, we will stay in your hotel." "Please tell me. "Okay." Mr. Liu Jianming said confidently. "If I divide my group evenly into four groups, there will be one more person, and then divide each group equally into four, and there will be one more person, and then divide the four groups equally into four, and there will be one more person. One person, of course, including me, how many people do we have at least?" "How much per person?" Mr. Liu Jianming immediately thought about it, he must take over the business, "There is no specific number, how should we start? As expected of a shrewd businessman, he quickly knew the answer: "At least eighty-five people, right?" Mr. Yu Jiang said happily: "That's right, eighty-five people, please." "How did you calculate it?" "The smallest number of people is the last quarter-dividing, and each portion is one person. From this we can conclude: before the third quarter, there are 1×4 1=5 (people), and the second time Before the division, there were 5 × 4 1 ??= 21 (people), and before the first division, there were 21 × 4 1 ??= 85 (people)." "Okay, we will stay here today." "How many men and women do you have? "There are 55 men and 30 women." "We only have rooms for 11 people. How do you want to live in rooms for 7 people and 5 people?" "Of course, sir, you have arranged it." Men and women are separated, and there can't be any empty beds." Another question came up. Liu Jianming had never encountered such a guest before, so he had to put some thought into it. After thinking hard, he finally came up with the best plan: two rooms for 11 people, four rooms for 7 people, and one room for 5 people for men; one room for 11 people, two rooms for 7 people, and one room for 5 people for women. Yes, 11 rooms per ***. After seeing his arrangement, Mr. Yu Jiang was very satisfied and immediately went through the accommodation procedures. A big business was done. Although it was a bit complicated, Mr. Liu Jianming was still very happy.

4. Mathematics in Life 7 stories, no less than 400 words,

This afternoon, my mother and I went to the supermarket to buy things.

When we finished buying what we needed and were about to leave, I saw ham sausages on the shelves, so I asked my mother to buy some ham sausages, and my mother agreed. But just after walking a few steps, I saw packs on the shelf again, of the same brand, same weight, containing 10 sticks, priced at 4.30 yuan per pack. Should I buy a pack or a stick? I hesitated. Suddenly, my mind turned around, I just need to compare and buy whichever one is more cost-effective. So I started to calculate: if I buy 10 pieces at retail, each piece costs 4 jiao, which is 40 jiao, which is equal to 4 yuan, and the whole package costs 4.30 yuan, which is 3 cents more, so I decided to buy it in bulk. I told my mother my calculation process, and she praised me for being fond of using my brain.

Also, tonight, I saw a confusing math problem. The title is: 37 students want to cross a river. There is an empty boat at the ferry that can only hold 5 people. If they all want to cross the river, how much should they use at least this boat? Second-rate?

Careless people often ignore the "empty boat", that is, they forget to have a punting boat, so they can only take 4 people at a time. In this way, there are 37 people minus one classmate who punts the boat, leaving 36 students. 36 divided by 4 equals 9. The last classmate who worked as a boatman on the other side also went ashore 4 times, so it takes at least 9 trips.

5. A short mathematical story of 400 to 500 words

The story of the mathematician Gauss when he was a child

Adding from one to a hundred

Gauss has many interesting stories. The first-hand information of the stories often comes from Gauss himself, because in his later years he always liked to talk about what happened when he was a child. We may doubt the authenticity of the stories, but many people have confirmed what he said. story.

Gauss's father was the foreman of a brickwork factory, and he always had to pay wages to the workers every Saturday. In the summer when Gauss was three years old, when he was about to pay his salary, little Gauss stood up and said, "Dad, you made a mistake." Then he said another amount. It turned out that the three-year-old little Gauss was lying on the floor, secretly following his father to calculate how much wages should be paid to whom. The recalculation results proved that little Gauss was right, which shocked the adults standing there with their mouths agape.

Gauss often said with a smile that he had learned to calculate before he learned to speak. He also often said that he learned to read by himself after asking adults how to pronounce letters.

At the age of seven, Gauss entered St. Catherine Elementary School. When I was about ten years old, my teacher gave me a difficult problem in arithmetic class: "Write down the integers from 1 to 100, and then add them up!" Whenever there was an exam, they had the following habit: the one who finished first Just put the slate (common at that time, used for writing) face down on the teacher's desk. The second person who finished finished placed the slate on the first slate, and they fell one by one. Of course, this problem will not be difficult for those who have learned arithmetic progressions, but these children have just begun to learn arithmetic! The teacher thought he could take a break. But he was wrong, because in less than a few seconds, Gauss had already put the slate on the desk and said at the same time: "Here is the answer!" The other students added up the numbers one by one, sweat broke out on their foreheads, but Gauss sat quietly, paying no attention to the contemptuous and suspicious eyes cast by the teacher. After the exam, the teacher checked the slates one by one. Most of them did it wrong, and the students were whipped. Finally, Gauss's slate was turned over, and there was only one number on it: 5050 (Needless to say, this is the correct answer.) The teacher was surprised, and Gauss explained how he found the answer: 1+100=101, 2+99= 101, 3 + 98 = 101,..., 49 + 52 = 101, 50 + 51 = 101. There are 50 pairs in a day and the sum is 101, so the answer is 50 × 101 = 5050. It can be seen that Gauss found the symmetry of the arithmetic series, and then put the numbers together in pairs just like the process of finding the sum of general arithmetic series.

6. Mathematics story for fifth graders, about 300-400 words. Urgent is best. Answer within 20 minutes

Newton: Do everything silently and carefully

Newton loved reading since he was a child, was very diligent, and especially liked handicrafts. He used the pocket money given to him to buy carpentry tools. He made many exquisite windmills, kites, sundials, clepsydras and other practical instruments. Newton did not show any extraordinary talent as a boy. The difference is that the hands-on ability is quite strong. Every time he made something, he always worked hard without saying a word. If it's not done properly, just dismantle it and redo it, never sloppily. Newton was very diligent, and his academic performance could not keep up with others. In particular, he spent most of his life in the laboratory. He often stayed up all night doing experiments, sometimes working in the laboratory for six weeks in a row, regardless of daytime. and night until the experiment is completed.

Although Newton was a great scientist, he was never complacent. He modestly said: On the road of science, we are just children playing on the beach and accidentally picking up a beautiful stone. As for the ocean of truth, I haven’t discovered it yet!

Newton was so humble and devoted himself to studying knowledge!

7. Mathematics Short Stories for Grade 5 (Less)

The "Bagua" shaped web made by a spider is a complex and beautiful octagonal geometric pattern. Even if people use a ruler It is also difficult to draw a pattern as symmetrical as a spider web with a compass.

In winter, cats always hold their bodies into a ball when sleeping. There is also mathematics in this, because the spherical shape minimizes the surface area of ??the body, thereby emitting radiation. It also has the least amount of heat.

The real mathematical "genius" is the coral polyp. It records the "calendar" on its body. They "carve" 365 spots on their body wall every year, which is obviously One "paint" a day. Strangely, paleontologists found that coral polyps 350 million years ago "painted" 400 "watercolor paintings" every year. Astronomers tell us that at that time, the earth had only 21.9 hours in a day, and a year was not 365 hours. Days, but 400 days.

10. Tang Seng and his apprentice pick peaches

One day, Tang Seng ordered his apprentices Wukong, Bajie and Sha Seng to go to Huaguo Mountain to pick some peaches. After a while, the three apprentices came back happily after picking peaches. Master Tang Seng asked: How many peaches did each of you pick? Bajie said with a smile: Master, let me test you. There are less than 100 peaches in my basket. If I count 3 by 3, there will be 1 left at the end. How many peaches did each of us pick?

Sha Monk mysteriously? Said: Master, let me test you too. If you count the peaches in my basket 4 by 4, how many peaches are there for each of us?

Wukong smiled and said: Master, let me test you too. If you count the peaches in my basket 5 by 5, how many peaches are left for each of us?

11. The skills of ">", "<" and "="

A long time ago, the kingdom of mathematics was chaotic and without any order. Not only were the ten brothers 0~9. The number angels were very angry when they saw this situation, so they sent three little angels "＞", "＜" and "=" to the mathematics kingdom. They were asked to bring order to the kingdom. The three little angels came to the Kingdom of Mathematics. Brothers 0 to 9 stared at them with disdain. "9" asked: "What do you three do? Our kingdom is not peaceful." Welcome. "

"=" The angel smiled and said: "We are the judges sent by angels to your kingdom to help you govern your country. I am the number on both sides of the 'equal sign'. They are always equal; these two are 'greater than' and 'less than'. Whoever the opening is facing is bigger, and whoever the pointed tip is facing is smaller. When the ten brothers heard that they were sent by the angel of numbers, they were always equal. The judges, as well as the introduction of "=", all obeyed the orders of ">", "<" and "=". From then on, the mathematical kingdom became more and more powerful, and there was a very strict order that no one would violate. .

12. The story of "0"

Roman numerals use several symbols to represent numbers, and they are combined to represent different numbers according to certain rules. In this use of numbers, the number "0" is not needed. At that time, a scholar in the Roman Empire discovered the symbol "0" from Indian notation. He found that with "0", it is extremely convenient to perform mathematical operations, and also introduced the Indian method of using "0" to everyone. This matter was known to the Roman Pope at that time. The pope was very angry. He rebuked that the sacred numbers were created by God, and there was no monster "0" in the numbers created by God. So he ordered that the scholar be caught and his ten fingers tightened with clamps. The clamping made his hands crippled and he could no longer hold a pen and write. In this way, "0" was expressly banned by the ignorant and cruel Pope of Rome.

However, although the use of "0" was prohibited, Roman mathematicians still used "0" secretly in mathematical research regardless of the ban, and still used "0" to make many mathematical contributions. Later, "0" was finally widely used in Europe, while Roman numerals were gradually phased out.

13. The oldest interesting mathematical problem

There are seven cats in each of the seven houses; among these seven cats, no matter which one, Seven mice were caught; and each of these seven mice had to eat seven ears of wheat; if each ear of wheat could peel off seven grains of wheat, what would happen: house, cat, mouse, ears of wheat, wheat? grains, what is the total number of grains if you add them all together?

Answer: The total number is 19607

There are 7 houses, 7X7=49 cats, 7X7X7=343 mice, 7X7X7X7=2401 wheat ears, and 7X7X7X7X7 wheat grains. =16807 combined. The total sum is 7+72+73+74+75=19607

14. Honeycomb Conjecture

The honeycomb is a very precise construction project. When bees build a nest, young worker bees are responsible for secreting pieces of fresh beeswax, each piece is only the size of a needle, while other worker bees are responsible for carefully placing the beeswax in certain positions to form a vertical six-sided cylinder. The thickness and error of each beeswax partition wall are very small. The six partition walls are exactly the same width, and the angle between the walls is exactly 120 degrees, forming a perfect geometric figure. People have always wondered why bees don't make their hives triangular, square or other shapes? Why are the partition walls flat instead of curved? Although the honeycomb is a three-dimensional building, each hive is a six-sided cylinder. , while the total area of ??the beeswax wall is only related to the cross-section of the hive. This leads to a mathematical problem, which is to find the plane figure with the largest area and smallest perimeter.

15. A snail climbs a well

German mathematician Reiss once asked such a mathematical problem: a well is 20 feet deep, and a snail is at the bottom of the well. It climbs 7 feet during the day and descends 2 feet at night. How many days does it take to reach the top of the well?

Analysis: If you think the answer is 20/(7-2)=4, you are totally wrong! The key to solving this problem is to consider the crawling situation on the last day differently from the crawling situation in the previous days.

Solution: The height of the snail crawling day and night in the first 3 days:

(7-2) × 3 = 15 (feet) The time of the last day of crawling: *** Time spent:

16 Measuring the Height of the Pyramid

One day, Thales saw people looking at the notice, and he also went up to look. It turned out that the notice said that the Pharaoh was looking for the smartest person in the world to measure the height of the pyramid. Thales went to Pharaoh. The Pharaoh asked Thales what tools he used to measure the pyramids. Thales said that he only used a stick and a ruler, which everyone thought was strange. He stuck the stick next to the pyramid, and when the shadow of the stick was as long as the stick, he measured the pyramid. He measured the length of the pyramid's shadow and half the length of the side of the pyramid's base. Add these two lengths together to get the height of the pyramid. Thales was truly the smartest man in the world. He easily measured the height of the pyramid without climbing to the top.

About 1,500 years ago, European mathematicians did not know how to use "0". They use Roman numerals. Roman numerals use several symbols to represent numbers, and according to certain rules, they are combined to represent different numbers. In this use of numbers, the number "0" is not needed. At that time, a scholar in the Roman Empire discovered the symbol "0" from Indian notation. He found that with "0", it was extremely convenient to perform mathematical operations. He was very happy and introduced the Indian method of using "0" to everyone. After some time, this matter was known to the Pope of Rome at that time. It was the Middle Ages in Europe, the church was very powerful, and the power of the Pope far exceeded that of the emperor.

The Pope was very angry. He rebuked that the sacred numbers were created by God. There is no monster "0" in the numbers created by God. Whoever wants to introduce it now is blaspheming God! So, the Pope ordered that the scholar be arrested and tortured. His ten fingers were clamped tightly with clamps, which made his hands disabled and he could no longer hold a pen and write. In this way, "0" was expressly banned by the ignorant and cruel Pope of Rome. However, although the use of "0" was prohibited, Roman mathematicians still used "0" secretly in mathematical research regardless of the ban, and still used "0" to make many mathematical contributions. Later, "0" was finally widely used in Europe, while Roman numerals were gradually phased out. The following is a short story, a story between numbers. One day, while the number cards were having lunch together, the youngest one started talking. Brother 0 said: "Let's take some photos together, what do you think?" Brother 0 said in unison: "Okay." Brother 8 said: "Brother 0 has a really good idea. Not bad, I’ll just be a good person for once. I, Lao 8, will supply cameras and film, okay?” Lao 4 said, “Brother 8, that’s good, but it’s a little too troublesome. Why don’t you just use my digital camera?” That's it." So they got busy and finally took the photo for them. They immediately sent the digital camera to the printing shop. The printing was done. The computer sister wanted money from them, but who were they? What about paying? They looked at each other blankly one by one. This is what the computer sister said: "One *** five yuan. You have eleven brothers and sisters. How much does each of you pay on average?" Among them, the sixth one is the smartest. This time it was the first to calculate the result. Do you know how it calculated it? When Gauss was in primary school, one time after the teacher finished teaching addition, because the teacher wanted to take a break, he asked the students to do calculations. The question was: 1 2 3 ..... 97 98 99 100 = ? The teacher was thinking, now the children must wait until get out of class is over! Just when he was about to make an excuse to go out, he was stopped by Gauss! ! It turns out that Gauss has already calculated it. Children, do you know how he calculated it? Gauss told everyone how he calculated it: add 1 to 100 and 100 to 1 in two rows, that is to say: 1 2 3 4 ..... 96 97 98 99 100 From then on, Gauss's primary school learning The process has already surpassed other students, which laid the foundation for his future mathematics and made him a mathematical genius!

8. Fifth grade mathematics diary of more than 400 words

Mathematics diary

This morning, I I am worrying about what to write in my math diary. Wandering around on the Internet, hoping to come across some inspiration. Suddenly, an article on Zhizhi attracted me:

"Xu Ruixiang, Class 6 (7), Eight-Road Experimental Primary School

This afternoon, I read "Double Color Course for Primary School Students" Here is a question.

The radius of the base of a cone is 8 decimeters, and the ratio of the length of the height to the radius of the base is 3:2. What is the volume of this cone in cubic decimeters?

Analysis: This is a proportional word problem..."

I didn’t look at the analysis and just pondered over this question, huh? I have never learned how to calculate the area of ??a cone. So how do I solve this problem? I sighed and prepared to continue reading the analysis, but then I thought again, will I be in sixth grade soon after this summer vacation? If I can't even do the questions in this class. Am I still in the Mathematical Olympiad class? Doesn’t it just live up to its name? Yes, I must figure it out on my own.

Normally when faced with this kind of question, I must build a model in my mind. However, I was extremely cautious about this question, for fear of making a mistake. I drew a cone in perspective on the paper.

Take a closer look, huh? If this figure were a plane figure, wouldn't it be the same as a triangle? Then wouldn't the cubic area of ??this cone be 1/2 of the area of ??a cylinder with the same base and height as it? I was overjoyed all of a sudden. It turns out that the area of ??a cone is also easy to find. As long as you know the height and base area of ??the cone, can't you find it? Let's go back to this question. The conditions tell you the radius of the base, which is equivalent to telling the base area. It says the height and base radius. The ratio is 3:2, that is, the length of the base radius is 2/3 of the height. That height is radius × 3÷2 = height. In this way, the height is 12 decimeters, the base area is 200.96 cubic decimeters, and the area of ??the cone is 200.96×12÷2=1205.76 cubic decimeters.

"Phew, I finally solved it." I breathed a long sigh of relief. Through this question, I also discovered that in fact, many things in mathematics are connected, such as the area of ??a cone. Same as the area of ??a triangle. In fact, you don’t need to know all the calculation formulas. As long as you can understand them, you can still solve the problem.

9. A short story about a mathematician in 400 words

When Hua Luogeng was in elementary school, a teacher introduced the school to the new teacher and said that the students in this school were all from poor families. Most of the children are stupid... These words deeply hurt Hua Luogeng's heart, and he was determined to repay the teacher with excellent results.

One day, the math teacher gave everyone an interesting problem: "There is something that I don’t know how many there are. If you count three or three, you will get two. If you count five or five, you will get three." "There are two left after counting seven to seven."

The whole class looked at each other and couldn't answer. Only Hua Luogeng stood up and said, "Teacher, I know, yes." '23'." The whole class was shocked, and the teacher nodded in praise. From then on, he fell in love with mathematics class.

While he was studying, the business of his father's shop was declining and he could no longer afford to continue his studies, so he had to drop out of school and work at the counter. He started self-study using an algebra book, a geometry book, and a calculus book with only 50 pages left. There was no time during the day, so at night I watched the small oil lamp and calculated over and over again. His father called him a "nerd" and forced him to burn his books several times. His neighbors also persuaded him to do business well.

Unfortunately, he suffered from terrible typhoid fever again. The doctor shook his head and sighed and asked his family to prepare for his "future". He challenged the god of death, struggled to work in the fields, and his left leg was broken again and became disabled. He was not discouraged and continued to exercise with a cane and endured the pain. After practicing enough to walk, he went to a middle school to do chores, fetch water for the teacher, and sharpen pencils. Even so, he did not give up self-study.

Not long after he started working in a middle school, he began to submit mathematics papers to newspapers and periodicals, and he was not discouraged even after they were rejected many times. Later, he published the article "The Reasons Why Su Jiaju's Algebra's Solution to the Quintic Equation Cannot Be Established", which was appreciated by Xiong Qinglai, a dean of mathematics, who quickly introduced him to Tsinghua University and placed him next to him.

(9) A 400-word mathematical story in life for fifth grade extended reading

Hua Luogeng’s growth history

Born on November 12, 1910 in Jintan District, Changzhou, Jiangsu Province , He loved to use his brain when he was young, and was often nicknamed "a fool" by his peers because he was too attentive in thinking about problems. In 1922, after graduating from Renyuan Primary School in the county town at the age of 12, he entered Jintan County Junior High School. Teacher Wang Weike discovered his mathematical talent and tried his best to cultivate it.

In 1925, after graduating from junior high school, he enrolled in Shanghai Zhonghua Vocational School. He dropped out of school because he could not afford the tuition. He dropped out and went home to help his father run a grocery store. Therefore, he only had a junior high school diploma in his life. After that, he spent 5 years studying all the mathematics courses in high school and junior college by himself.

In the autumn of 1927, he married Wu Xiaoyuan. In the winter of 1929, he unfortunately contracted typhoid fever, leaving his left leg permanently disabled and having to use a cane to walk. In 1929, Hua Luogeng was employed as a clerk at Jintan Middle School and began to publish papers in Shanghai Science and other magazines.

In the spring of 1930, Hua Luogeng published "The Reasons Why Su Jiaju's Algebraic Solution to the Quintic Equation Cannot Be Established" in Shanghai Science magazine, which caused a sensation in the mathematics community. In the same year, Xiong Qinglai, director of the Department of Mathematics at Tsinghua University, learned about Hua Luogeng's self-study experience and mathematical talent, and broke the rules and allowed Hua Luogeng to join the Tsinghua University Library as a librarian.

In 1931, he served as an assistant in the Department of Mathematics at Tsinghua University. He taught himself English, French, German, and Japanese, and published three papers in foreign magazines. In 1933, he was promoted to assistant coach. In September 1934, he was promoted to lecturer.
