Little knowledge of mathematics in life 100 words

1. Mathematical stories in life 100 words, 3 articles are urgent.

One Sunday morning, my parents and I watched TV at home. There was a basketball game on TV.

After watching it for a while, my father suddenly said to me, "Qiqi, let me test you a math problem to see if you can?" I opened my mouth and said, "OK, no problem." Dad thought for a moment and said, "suppose the red team throws eight balls a minute and the blue team throws six balls a minute." After eight minutes of pitching together, the blue team improved its hit rate 10 ball per minute, while the red team only threw six balls per minute because of physical exhaustion. How many minutes later, the red team and the blue team threw the same number? " I thought for a while, but it took him a long time to figure it out.

As time went by, I really couldn't think of it, so I had to say shyly, "I can't do it without a draft." I know that even if I have a draft, I may not be able to do it.

At this moment, my mother said to me: "It turns out that the red team throws two more shots a minute than the blue team, and one * * * throws eight minutes, which is 8*2= 16 (one); Later, the blue team overtook the red team and threw four more balls per minute. How many minutes does it take to throw 16 balls? 16÷4=4 (minutes), it takes 4 minutes to catch up. " I said, "It's so simple! Why didn't I think of that? " Dad smiled and said, "Is it simple? This shows that there is something wrong with your thinking.

In real life, we should be good at discovering things and finding out their laws, then you will feel that mathematics in life is much more interesting than that in class. Through this incident, I found that mathematics in life is indeed everywhere, everywhere in life and study.

From then on, I like math more! Comments (2)3 148 Other answers (2) An enthusiastic friend, animal mathematical meteorologist Lorenz, published a paper entitled "Will butterflies flap their wings to cause tornadoes in taxonomic groups?" This paper discusses that if the initial condition of a system is a little worse, its result will be very unstable. He called this phenomenon "the butterfly effect". Just like we roll the dice twice, no matter how deliberately we roll, the physical phenomena and points thrown twice are not necessarily the same.

Why did Lorenz write this paper? This story happened in the winter of 196 1 2008. He operated the meteorological computer in the office as usual. Usually, he only needs to input meteorological data such as temperature, humidity and air pressure, and the computer will calculate the possible meteorological data at the next moment according to the built-in three differential equations, thus simulating the meteorological change map.

On this day, Lorenz wanted to know more about the subsequent changes of a record. He re-entered the meteorological data at a certain moment into the computer, so that the computer could calculate more subsequent results. At that time, the speed of computer processing data was not fast enough, so he had time to have a cup of coffee and chat with friends for a while before the results came out.

An hour later, the result came out, but he was dumbfounded. Compared with the original information, the original data is similar, and the later data is more different, just like two different pieces of information.

The problem is not the computer, but the data he entered is 0.0005438+027. These subtle differences make a world of difference. So it is impossible to accurately predict the weather for a long time.

Cao Cao's Gourd (Volume II)-Yuan Zhe Science Education Foundation II. The mathematical "genius" hive in animals is a strict hexagonal cylinder with a flat hexagonal opening at one end and a closed hexagonal diamond bottom at the other end, which consists of three identical diamonds. The rhombic obtuse angle of the chassis is 109 degrees 28 minutes, and all acute angles are 70 degrees 32 minutes, which is both firm and material-saving.

The honeycomb wall thickness is 0.073 mm, and the error is very small. Red-crowned cranes always move in groups, forming a "human" shape.

The angle of the herringbone is 1 10 degrees. More accurate calculation also shows that half the angle of the herringbone-that is, the angle between each side and the direction of the crane group is 54 degrees, 44 minutes and 8 seconds! And the angle of diamond crystal is exactly 54 degrees, 44 minutes and 8 seconds! Is it a coincidence or some "tacit understanding" of nature? The spider's "gossip" net is a complex and beautiful octagonal geometric pattern, and it is difficult for people to draw a symmetrical pattern similar to a spider's net even with the compass of a ruler.

In winter, when a cat sleeps, it always hugs its body into a ball. There is also mathematics in it, because the shape of the ball minimizes the surface area of the body, so it emits the least heat. The real "genius" of mathematics is coral.

Coral writes a "calendar" on its body, and "draws" 365 stripes on its wall every year, apparently one a day. Strangely, paleontologists found that corals 350 million years ago "painted" 400 watercolors every year.

Astronomers tell us that at that time, the earth only had 2 1.9 hours a day, not 365 days a year, but 400 days. (Life Times) Comment (1)62 Baiyun Grade 8 2009-08-04 1. Q: It takes 1 minute to fry two cakes in a pan at a time, so it takes two minutes for a cake to go from the pan to * * *. At this rate, three cakes will be fried. A: Three minutes.

In the first minute, fry two cakes first; In the second minute, turn a cake upside down, take out another cake and put in a new cake; In the third minute, take out a cake fried on both sides, turn the other cake over, and then put the cake just fried on one side in. 2. Q: The seawater in a certain place 1000 kg contains 3 kg of salt. 1 kg of seawater is how many kg? 10 kg of seawater? Answer: 3÷ 1000=0.003 kg 3. Q: In our daily life, we often use a kind of transportation-bicycle, whose wheels are round. Do you know why? Can you briefly talk about why the axle should be placed in the center of the wheel with relevant knowledge? Answer: In order to keep the distance between the axle center and the ground stable when riding, the wheels are circles with the axle center as the center, so the wheels of bicycles are all round, and the axles should be placed in the center of the wheels.

2. Mathematics in life, 100 word composition

In life, we often use mathematics, and when buying and selling goods, we will use mathematics; Building a house will use mathematics; When calculating data, mathematics and so on will be used.

Looking back on a lot of mathematics knowledge I learned in primary school for six years, I constantly understand and apply it in my life, and feel that mathematics is around me, in my life. I remember when I was studying triangles in Book 9, the teacher told us a lot: draw triangles from the familiar red scarf, tripod of bicycle and famous pyramids in Egypt, and then understand the stability of triangles through practical activities such as pushing and pulling.

And use it to solve some practical problems in life. I also use this principle to repair the small stool at home and make it stable and strong, which has won unanimous praise from the whole family.

The mastery and application of knowledge is not a simple matter, and the awareness of application must be cultivated on the basis of full understanding. Our math teacher, Mr. Wang, also learned a lot when he explained this unit of statistics.

I don't know the expenses and expenses at home. After returning home, I collected and sorted out the receipts of home shopping, water and electricity bills, milk bills and my own tuition bills, and calculated them in categories. Haha, I finally know the daily expenses at home! Show it to mom and dad, and they laugh happily. Through these practical applications and operations, I once again realize the important role of practice in understanding, mastering and skillfully using knowledge.

My application ability has also been well cultivated. Because what you hear will be forgotten, what you see will be remembered, and what you experienced will be better understood and used.

By doing so, I not only learned knowledge, but also learned how to solve practical problems. Let mathematics exist all the time in life, let students practice what they have learned and solve problems in life.

This afternoon, my mother and I went shopping in the supermarket. When we finished buying what we needed, we were about to leave. I saw sausages on the shelf, so I asked my mother to buy some sausages, and my mother agreed. But just after a few steps, I saw a package with the same brand and weight on the shelf, which contained 10 pieces at 4.30 yuan each. Do you want to buy a pack or a slice? I hesitated. Suddenly, my mind turned and I understood. Just compare and see which one is cost-effective. So I started to calculate: if I buy 10 pieces in retail, each piece costs 40 cents, 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 the process of my calculation, and my mother praised me for my love of brains.

4. What mathematical knowledge do you have in your life? Please make a list and use more words.

There are many mathematical problems around our lives, which run through all aspects of our lives. There are many math games in real life, such as children's quick calculation of 24 when playing poker, math box filling game, and even Zhao Benshan's sketches have many such math games, such as "seven monkeys in the tree, a monkey on the ground, and a few monkeys." And so on. These games constitute a colorful picture in our life. We get together every morning. First of all, we make a relatively simple plan for the day's work, what to do in a day, when to finish it, and what is the budget expenditure and income of this day; After having a preliminary plan, start to implement the work of the day; A day's work is accompanied by various calculations, and the budget is mathematics. After a day's work, the next step is the summary of the day. Summarized by a mathematical operation, the result of the operation is a relatively intuitive number. In our real life, shopping, estimating, calculating time, determining location and buying and selling stocks are all related to mathematics. It can be said that mathematics is everywhere in people's lives. Mathematics is an indispensable tool in daily life. No matter what occupation people are engaged in, they will use mathematical knowledge and skills and mathematical thinking methods to varying degrees. Especially with the popularization and development of computers, this demand is increasing day by day. Whether it is weather forecast, savings, market research and forecast in our daily life, or gene map analysis, engineering design, information coding, quality monitoring and so on. It is inseparable from the support of mathematics. Mathematics, like language, is a tool with international universality. It can be said that there are countless mathematics in nature, such as the honeycomb built by bees, whose surface is composed of wonderful mathematical figures-regular hexagon, which consumes the least material and time; The manhole covers of urban sewers are all round. Do you know why? On the sidewalk, we often see such patterns, which are paved with square or regular hexagonal floor tiles of the same size, so that the floor tiles of this shape can be paved into a flat ground without pores. Is there a mathematical truth of salvation in this? For another example, 100 households need to install telephones, but they don't need 100 telephone lines. As long as they are kept busy for a period of time, the installation cost can be greatly saved, which embodies the role of mathematical statistics. Therefore, life cannot be separated from mathematics, which is the epitome of life. At the end of the year, businessmen said that my new year was coming. Farmers are also talking about how much food they have earned this year; The workers are also discussing whether the income and expenditure of this year are equal and how much savings there are; The soldiers talked about their training achievements this year and how many achievements they improved; Students' academic performance is the standard to measure a teacher's efforts in the past year; The unit is also making such a summary. The end of one year is like this, and the beginning of the next year also needs a budget; People are doing the same thing every day, every month, every quarter and every stage; A person, a family, a unit, an organization, a country, etc. They all use mathematical methods to do certain operations on them in different time, place, space, people and things. And then get an intuitive numerical index as the goal, conclusion, budget, degree, etc. In short, mathematics in life can be said to be everywhere, and mathematics has a serious impact on our lives.

5. Mathematical knowledge in life

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.

During the National Day holiday, my mother and I went shopping in the supermarket to find kilograms and grams.

Walking into the supermarket, I first came to the biscuit cabinet. Among so many dazzling cookies, I chose my favorite casual cookie. I looked at it carefully, and finally found "net content 1 00g" in the corner, which means that the weight of this packet of biscuits excluding the bag is100g, so if there is10g of such biscuits, it is1kg. Then we went to the place where we bought rice. I found that a bag of rice costs 10 kg. If our family eats 2 kilograms a day, our family will eat 60 kilograms a month, which is six bags of rice.

Later, I saw that 16 eggs were about 1 kg, a pineapple was about 2 kg and a watermelon was about 3 kg. Today, I have gained a lot. I feel the knowledge of kilograms and grams learned in mathematics. Mathematics is really important in life. This afternoon, my mother and I went shopping in the supermarket.

When we finished buying what we needed, we were about to leave. I saw sausages on the shelf, so I asked my mother to buy some sausages, and my mother agreed. But just a few steps, I saw a pack of the same brand and weight on the shelf, 10, 4 pieces per pack.

30 yuan. Do you want to buy a pack or a slice? I hesitated.

Suddenly, my mind turned and I understood. Just compare and see which one is cost-effective. So I began to calculate: if the retail seller buys 10 pieces, each piece costs 4 cents, which is equal to 4 yuan, while the whole package costs 4 cents.

30 yuan, 30 cents more, so I decided to buy in bulk. I told my mother the process of my calculation, and my mother praised me for my love of brains.

I read a book today, and my heart is heavy. It tells the story of a mathematician. His family was poor, but he was eager to learn, so he was sent to school. But he's not serious. Keep playing. One day, the teacher talked to him: "The food you ate and the money you spent at school were all the fruits of your father's hard work. Who do you deserve if you don't study hard now? " He was inspired a lot. He thought: When I grow up, I want to be an astronomer and a writer.

But later, influenced by a teacher who came back from studying in Japan, he turned his interest to mathematics. Do you know who he is? He is Sue, a famous mathematician in China. Smoking is harmful to health. Dad smokes a newspaper every day, 20 cigarettes per pack. I learned that each cigarette can shorten people's life span by 3 minutes, and shorten people's life span by 20X3=60 minutes = 1 hour every day, and 365 days X 1 hour every year.

So I said to my father, "Smoking is harmful to health." .

7. Give some math stories and knowledge. Be brief.

One day, the Tang Priest told his disciples Wukong, Bajie and Friar Sand to go to Huaguoshan to pick peaches. Soon, the three disciples came back happily after picking peaches. Tang Priest and his disciples asked: How many peaches did each of you pick? Bajie said with a silly smile, Master, let me test you. Each of us took the same amount of money. There are less than 65,438+000 peaches in my basket. If you count three plots, there is still 1 left. Do you calculate how many peaches each of us picked? Friar Sand said mysteriously, Master, I will test you, too. If there are four peaches in my basket, there is 1 left in the end. Calculate, how many peaches did we each pick? Wukong smiled and said, Master, I'll test you, too. If you count five peaches in my basket, there is 1 left in the end. Calculate, how much will each of us choose? 2 Digital Fun Association Su Dongpo, a great poet in the Song Dynasty, went to Beijing with several schoolmates to take the exam when he was young. When they arrived at the examination center, it was too late. The examiner said, "I made an association. If you are right, I will let you into the examination room." The examiner's first association is: a single leaf in a boat, two or three students, four oars and five sails, passing through six beaches and seven bays, but it's too late. Su Dongpo has been tested three times and twice, and I must get a correct answer today. Examiners and Su Dongpo both embedded ten numbers from one to ten in couplets, which vividly described the hardships and assiduousness of literati. Learning mathematics with three wrong decimal points not only requires correct thinking, but also can't make mistakes in the specific problem-solving process. An old woman living on a pension in Chicago, USA, went home after a minor operation in the hospital. Two weeks later, she received a bill from the hospital for $63,440. When she saw such a huge number, she couldn't help being surprised. She had a heart attack and fell to the ground dead. Later, someone checked with the hospital, and it turned out that the computer misplaced the decimal point, but in fact she only had to pay $63.44. A wrong decimal point actually killed a person. As Newton said, "in mathematics, even the smallest error can't be made."

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.

/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 describes the spiral nature, but also symbolizes his love for mathematics.

5. 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.

6. 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", but there are different opinions on how much is left. Until the Three Kingdoms period, Liu Hui put forward a scientific method to calculate pi-"approximate the circumference of a circle with the circumference of 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 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 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".

Ju Lushi, born in 624 BC, 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.

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.

9. What is the common sense of mathematics in life?

There are many mathematical problems around our lives, which run through all aspects of our lives. There are many math games in real life, such as children's quick calculation of twenty-four when playing poker, math box-filling games, and even Zhao Benshan's sketches. For example, "There are seven monkeys in the tree, one on the ground and several others." Wait, examples from life. These games constitute a colorful picture in our life.

We get together every morning. First of all, we make a simple plan for the day, what to do in a day, what time it takes to finish it, and what is the budget expenditure and income of this day. After having a preliminary plan, start to implement the work of the day; A day's work is accompanied by various calculations and budgets, which is mathematics. After a day's work, the next step is the summary of the day. Summarized by a mathematical operation, the result of the operation is a relatively intuitive number.

In our real life, shopping, estimating, calculating time, determining location, buying and selling stocks and so on are all related to mathematics. It can be said that mathematics is ubiquitous in people's lives and it is an indispensable tool in daily life. No matter what occupation people are engaged in, they will use mathematical knowledge and skills and mathematical thinking methods to varying degrees. Especially with the popularization and development of computers, this demand is increasing day by day. Whether it is weather forecast, savings, market survey and forecast in our daily life, or gene map analysis, engineering design, information coding, quality monitoring and so on. It is inseparable from the support of mathematics. Moreover, mathematics, like language, is a tool with international universality. It can be said that there are countless mathematics in nature, such as the honeycomb built by bees, whose surface is composed of wonderful mathematical figures-regular hexagon, which consumes the least material and time; The manhole covers of urban sewers are all round. Do you know why? On the sidewalk, we often see such patterns, which are paved with square or regular hexagonal floor tiles of the same size, so that the floor tiles of this shape can be paved into a flat ground without pores. There is a mathematical truth in economics. For another example, 100 households need to install telephones, but actually they don't need 100 telephone lines. As long as they are kept busy for a period of time, the installation cost can be greatly saved, which embodies the role of mathematical statistics. So life and mathematics are inseparable. There is mathematics in life, and mathematics is the epitome of life.

At the end of the year, the businessman said in the conversation what my income was this year and how it compared with last year. Farmers are also talking about how much food they have earned this year; The workers are also discussing whether the income and expenditure of this year are equal and how much savings there are; The soldiers talked about their training achievements this year and how many achievements they improved; Students' academic performance is the standard to measure a teacher's efforts in the past year; The unit is also making such a summary.

The end of one year is like this, and the beginning of the next year also needs a budget; People are doing the same thing every day, every month, every quarter and every stage; A person, a family, a unit, an organization, a country, etc. They all use mathematical methods to do certain operations on them in different time, place, space, people and things. And then get an intuitive numerical index as the goal, conclusion, budget, degree and so on.

In a word, mathematics in life can be said to be ubiquitous, which seriously affects our lives and is an important condition in life. Therefore, we can't ignore the mathematics in life, we should attach importance to it and develop and use it to the maximum.
