There are ants, bees and red-crowned cranes.

A gifted mathematician, the bee. /kloc-at the beginning of the 0/8th century, French scholar Marah measured the de dimensions of a large number of beehives, which surprised him. All obtuse angles of the rhombus formed by these beehives are109 28', and all acute angles are 70 32'.

Later, French mathematician Koenig Ho and Scottish mathematician Mark Lorraine calculated theoretically that if the de material is to be consumed at least, the largest de diamond container should be made from this angle. In this sense, bees can be called "gifted mathematicians and designers".

Ant crane Red-crowned crane de arithmetic is plain, and ant de calculation skills are also very superb. British scientist Henston did an interesting de experiment.

He cut a dead grasshopper into three pieces, the second piece was twice as big as the first piece, and the third piece was twice as big as the second piece. Forty minutes after the ant colony discovered these three foods, the smallest grasshopper gathered 28 de ants, the second one had 44, and the third one had 89, and the latter group was almost twice as many as the former one.

It seems that the multiplication and division of ants is quite good. Red-crowned crane, a rare animal in China, always migrates in groups, forming a "human" shape.

The de angle of this herringbone is always around 1 10. If calculated more accurately, the de angle of herringbone is half, that is, the de angle between each side and the direction of the red-crowned cranes is 54 44' 08 ",which is the same degree as the de angle of the hardest de diamond crystal in the world. Is this coincidence or some natural de "fit"? .

2. A short math story

1 0 and its digital brothers One day, a group of special "guests" came to the forest.

They look very special, and the animals are very strange. They are asked to introduce themselves one by one. The first one out was a thin man. The thin man said, "I am 1, as thin as a pencil."

Then another one came out and said, "I am 2, floating on the water like a duckling." The third said, "I'm 3, and I sound like an ear flower."

"I am four years old, like a flag fluttering in the wind." "I am five years old, and I hang my coat like a clothes hook."

"I'm 6 years old and I smile like a bean sprout." "I'm 7, and I like to cut grass with a sickle."

"I am 8, like a twist." "I am 9 years old, just like a spoon can hold rice."

"I am 0, like an egg making a cake." As soon as they were introduced, the deer asked, "Who is the oldest among you? Who is the youngest? " 9 stood up and said proudly, "I am 9, I am the oldest."

0 hung his head and said, "I am the youngest." "Yes, it is this meaningless 0."

No.9 said in a cold tone. Just after that, the animals and their digital brothers all laughed.

0 is even more embarrassing. Animals don't want to play when they see that 0 is so useless They sing together! Jump! Very happy.

Suddenly, an elephant struggled in it for a long time. It has been trying to climb up with great strength. He was so tired that he was sweating profusely, his legs were torn and his blood was flowing. However, it couldn't climb up, so it had to shout "help!" Help! "When the animals heard this, they rushed to the hole and tried to save the elephant.

The number 1 to 9 also came to help. They formed the largest number, 98765432 1, showing the greatest strength. They made great efforts, but they didn't pull the elephant up.

At this moment, I only heard a faint voice behind me saying, "I'll try." As soon as they saw that it was zero, they reluctantly agreed, which was also helpful.

They regrouped into the number 98765432 10, and their strength suddenly increased by 10 times. Ha ha laugh ... I immediately pulled the elephant up.

The animals are grateful to the digital brothers, but they also feel guilty for being left out. They all come from 0 and want to be friends with 0. Digital brothers also began to pay attention to 0 and are willing to play it.

Since then, I have never felt inferior, and I feel that I am still very useful. 2. Beautiful tree planting patterns Long ago, the king of the digital kingdom celebrated his 20th birthday, and the Roman digital kingdom sent 20 precious trees as birthday gifts.

* * * Count. Minister "20" posted a list of talents, and whoever can plant these 20 trees skillfully will be rewarded.

But no one can design it. Minister "20" thought day and night, turned over a lot of materials and conducted experiments again and again with stones.

He painted thousands of patterns. Painting, trying, suddenly, his eyes lit up and he saw an extremely beautiful pattern.

Minister "20" immediately presented this design to the king. The king was very happy when he saw it. "20" The minister pointed to the pattern and said to the king, "Your Majesty, look, the number of trees in the painting is four in horizontal, vertical and oblique directions, so there are at most 18 rows."

The king said in surprise, "I have never seen such a beautiful and wonderful tree planting pattern in any park." It's fantastic. I will reward you! " .

I will reward you! The king said in surprise, "I have never seen such a beautiful and wonderful tree planting pattern in any park." It's fantastic. I will reward you! " "Yes, it was invented and designed by a mathematician named Sam Lloyd. I just used his designs to plant trees. "

Minister No.20 told the truth. "Good, good, you can use this pattern, which is also a meritorious service."

As he spoke, the king announced the reward for the "20" minister and named the pattern "20 Pattern", which is the most beautiful tree planting pattern in the world. The king immediately sent someone to plant twenty trees in the palace garden according to the "Twenty Styles".

Since then, this beautiful tree planting pattern has been passed down to this day. 3. The butterfly effect meteorologist Lorenz put forward an article entitled "Can 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 throw the dice twice, no matter how deliberately we throw them, the two things are 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 results 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. References:

Cats are small animals that people often see. Many people like kittens because they are cute. If you carefully observe the kitten, you will find that in winter, when the kitten sleeps, it always curls up into a sphere, which also has mathematical factors, because the sphere makes the cat's body surface area smallest, so it emits the least heat.

Coral can be said to be a natural mathematical "genius". Corals can write a "calendar" on themselves. They "draw" 365 stripes on their body walls every year, and of course, "draw" one a day.

However, paleontologists found that corals 350 million years ago "painted" 400 watercolors every year. Astronomers tell us that the earth is only 2 1 a day.

Nine hours, not 365 days a year, but 400 days.

4. Inspiration from the "genius" of animal mathematics 100 words.

Red-crowned cranes have a strong sense of self-protection. 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 mathematical genius of bees is reflected in their cognition of geometry. Honeycomb is a strictly 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.

After reading these, do you also deeply admire the strange animal world in nature? Perhaps human beings have their own various knowledge systems and talented people come forth in large numbers, but in the animal kingdom, "animal talents" abound.

5. What are the little knowledge of scientific animals?

Dog fish-the longest-lived fish has the highest IQ-the smallest bird-the hummingbird's most dangerous poisonous spider: the largest gecko funnel web spider in Sydney-the most biting animal of gecko-the marsupial, the Tasmanian devil king cobra-the most dangerous snake in the world, the shortest-lived vertebrate, the smallest animal goby-a protozoan with code H39, and the smallest bear in the world. The largest turtle in Guyana-the elephant turtle-the largest animal in the world-the blue whale is the longest-lived animal among mammals. It is said that it can live for 60 to 70 years. Of course, wild land is different from artificial farming, and the former has a shorter life span. According to records, the long-lived elephant in Golpagos Islands can live 180 to 200 years old. The fastest animal is the cheetah. It can run 1 10 km. Cheetah is a carnivorous cat, which preys on deer and antelope. When deer, antelopes and other animals run hard, the speed will not exceed 70 kilometers per hour, so they will be caught soon. But if the distance is not very short, the cheetah can't keep the fastest speed, so try to catch its prey as close as possible. The most powerful animal lion is called "the king of beasts", but it doesn't attack elephants. A few lions who attack baby elephants have never heard of being trampled to death by the mother elephant. However, some tigers that attacked elephants in India were trampled by elephants. It seems that the most powerful animal is the elephant. The cleverest animals and mammals are chimpanzees. There are apes similar to humans, gorillas belonging to the ape family in zoology, orangutans, gibbons and dark orangutans in Baltic countries. Among them, chimpanzees are the cleverest. Although its brain capacity is only 400 ml, it is not as good as 500 ml of gorilla. However, its brain function is particularly remarkable. Apart from insects, the shortest-lived animal is a mouse born in the Xiayi swamp in Hokkaido. It was born in spring and died the next day. Its life span is only eight to ten months. However, if fed indoors, it can live for two or three years. The heaviest animal is, of course. It is equivalent to five or six elephants. Elephants are divided into Indian elephants and African elephants. The former is relatively small, weighing about 4000 to 5000 kilograms, and the heaviest elephant is 8000 kilograms. African elephants weigh 6000 to 7000 kilograms, and the highest record is 12000 kilograms. The smallest sea crab, the bean crab living in Sagami Bay, Japan, is 3.8-4.2 mm, only as big as a grain of rice. The heaviest sea crab is found in bass strait. The largest lobster, weighing14kg, was caught by the deep-sea trawler "Hesper" on 1934. The weight from the tail end to the tong tip exceeds 65,438+09 kg. This big lobster is on display at the Boston Science Museum. The longest jellyfish was washed up on the beach in Massachusetts on 1965. If the tentacle is flattened, it is 74 meters long. The smallest lobster is the horned lobster in South Africa, with a total length of only about 10cm. The largest snail is the sea rabbit snail found on the coast of California, USA, with an average weight of 3.2-3.6 kg and the heaviest weight of 6.8 kg. The height of the largest snail shell is generally more than 20 cm, and the maximum is 40 cm. The most valuable shellfish experts believe that white-toothed agate shells living overseas in the Philippines are rare and precious. So far, three of them have been found. 1975 1 1 was captured on macri Island overseas and sold to the Japanese for $7,000. Among the marine animals that breathe with their lungs, the turtle holds its breath for the longest time underwater. You can stay downstream for days and nights. The most destructive insects are grasshoppers distributed in Africa and West Asia. Some weather conditions will cause swarms of grasshoppers to devour almost all plants encountered during the flight. The crops eaten by 50 million grasshoppers a day can feed 500 people a year. The fiercest birds live in the Andean vultures between the cliffs of the Andes in South America. Its body length can reach1.2m, and its wings can spread up to 3m. It has a strong and hooked "iron mouth" and sharp claws, and specializes in eating live animals, not only small and medium-sized animals such as deer, sheep and rabbits, but also large mammals such as cougars. Therefore, it is also called "the bird that eats the lion" and "the king of birds". The biggest animal among other animals: the blue whale _ _ the longest-lived animal: the turtle _ _ the tallest animal: the giraffe _ _ the animal with the most feet: the millipede _ _ the swimming champion among other animals: the dolphin _ the ship in the desert: the camel. The biggest land animal: the elephant _ _

6. Little knowledge of mathematics in life: Why do cats sleep?

Math Tips in Life: Why do cats curl up when they sleep? "Cat cakes" and "jiaozi the dog" began to appear in winter.

Even if the room is warm, they still like to form balls. Every time I see the fur balls sleeping in a circle, I really want to ask them if this wonderful posture with their heads pressed against * * * is comfortable! In fact, this sleeping position is uncomfortable, but why is the hairball still like this? Today, let's take a look at the math science in life with the geek math gang.

When sleeping, we can do an experiment: curl up first and then stretch out. I believe you can come to the conclusion right away that the first posture is warmer. It's the same for a cat to curl up when sleeping, because it can greatly reduce the contact area with cold air, emit the least heat, and of course be warmer.

If the cat is also a mathematician, it will come to the conclusion that the surface area of a sphere is the smallest when the volume is the same. Of course, cats don't know any mathematical principles. It just evolved the most suitable behavior for the environment in a long time, which is the wisdom of nature.

Nature is not eccentric, and this wonderful wisdom has also given many animals and plants. For example, a spider writes many secrets on its web.

Spider webs are symmetrical, complex and beautiful. Even if carpenters use compasses and rulers, when scientists study spider webs with mathematical equations and coordinate systems, they are shocked: complex mathematical concepts such as parallel lines, congruent corresponding angles, logarithmic spirals, catenary lines and transcendental lines are actually applied to this small spider web-no! Rather than saying that spiders apply mathematical principles, people feel the wisdom of nature from the exquisiteness of spider webs! Corals are smaller than spiders, and their bodies are natural history books. They write down an annual ring pattern on the body wall every day, 365 in a year and 366 in a leap year, which is extremely accurate. Biologists found through research that there were 400 annual rings on corals 350 million years ago, which indicated that there were only 2 1.9 hours in a day and night on the earth at that time, and there were 400 days in a year.

If it weren't for these corals, how could humans reproduce the appearance of the earth hundreds of millions of years ago? The well-known golden section of 0.6 18 is not exclusive to Mona Lisa and Venus-to be exact, artists who learn from nature have created beautiful works. If you carefully observe a maple leaf, you will find that the ratio of its vein length to leaf width is about 0.6 18.

The ratio of butterfly's body length to wing width and the diameter ratio of adjacent spirals on Nautilus shell are also close to 0.6 18. Even our favorite pattern-the five-pointed star, its beauty comes from mathematics.

We can find a picture of a regular five-pointed star, measure it with a ruler and calculate it. You will come to an amazing conclusion: every line segment on the five-pointed star conforms to the golden section.

In nature, starfish, carambola and dill are also perfect five-pointed stars. There is no shortage of mathematics in life. Observe carefully and love mathematics. You are a mathematician, too.

7. 100 word math story or knowledge

The story of flowers

From 65438 to 0946, Hua was invited to give lectures in the United States and was hired by the University of Illinois with a high salary.

He was hired as a tenured professor, and his family also settled in the United States, with a house and a car, and his life was very comfortable. At that time, many people thought that Hua would never come back. The birth of the new China touched China's love for the motherland. 1950, he resolutely gave up his comfortable life in the United States and returned to the motherland. He also wrote a letter to China students studying in the United States, urging them to return to China to participate in socialist construction. In his letter, he revealed a childlike heart that loves China: "Friends! Although Liangyuan is good, it is not the hometown of longevity. Go back and come back ... For the sake of the nation, we should go back ... "Although mathematics has no national boundaries, mathematicians have their own motherland.

The origin of * * * numbers

Xiaoming is a child who likes to ask questions. One day, he became interested in the numbers 0-9: Why is it called "* * * numbers"? So he went to ask his mother: "Since 0-9 is called' * * * number', it must have been invented by * * * people, mom?"

Mom shook her head and said, "* * * Numbers were actually invented by Indians. About 1500 years ago, Indians used a special word to represent numbers. There are 10 words, and you can write both strokes. Later, these figures were introduced into * * *. * * * people think these numbers are simple and practical, so they are widely used in their own countries and spread to Europe. In this way, it gradually became the number we use today. Because * * * people have played a great role in the spread of these numbers, people are used to calling them' * * * numbers'. "

Xiao Ming heard this and said, "So that's it. Mom, can this be called' making a mistake'? " Mom smiled.

Children's song competition

The animal school held a children's song competition, with the elephant teacher as the referee.

The little monkey raised his hand first and began to recite: "I can calculate carry addition, and the digits can only be added if they are aligned." The number of digits should be aligned with the number of digits. When the number of digits exceeds ten, the number of digits should be advanced to ten. Add ten and one to count quickly and accurately. "

As soon as the little monkey finished speaking, the puppy began to recite again: "abdication and subtraction are not difficult, just align the numbers." If the single digits are small enough, ten people can borrow one. If ten people return, one will be ten, and if they return, one will be missing. How to reduce ten digits, ten digits will be reduced again and again. "

Everyone applauded their wonderful performance. Teacher Elephant said, "Their nursery rhymes make us understand that both carry addition and abdication subtraction should win the championship, ok?" Everyone agrees and applauds them.

Skills of, and.

A long time ago, the kingdom of mathematics was chaotic. The 0-9 brothers not only dominate the kingdom, but also boast of their greatest skills. The math angel was very angry when he saw this situation. He sent three little angels to the math kingdom to establish order and avoid chaos.

Three little angels came to the kingdom of mathematics, and 0-9 brothers looked at them contemptuously. Q: "What are you three doing in the kingdom of mathematics? You are not welcome! "

He smiled and said, "We are judges sent by angels to help you govern your country. I am an equal sign, and these two are' greater than sign' and' less than sign'. Whoever they speak to is greater. Whoever they point to is small. "

When the ten brothers heard that they were judges sent by angels, they obeyed the orders of God and ... and from then on, the mathematics kingdom had a strict order, and no one would violate it.

8. Scientific knowledge about animals

Persimmons can't be eaten with crabs. 1) Rabbits beat the ground with their legs to transmit information, mostly with their hind legs, which is a way for them to express their feelings to female rabbits. (2) The largest monkey in the world is a baboon, and the smallest monkey is a bonobo. (3) Dogs wag their tails when they are happy. When they are angry, they straighten their tails backwards. Dogs only pick up their tails. (4) The leopard grinds its claws on the tree. The stag rubbed its horns on the trunk to sharpen them. Wild boars often grind their teeth on trees. (5) Polar bears wear thick white fur coats. Seals and walruses have thick fat to keep their bodies warm. (6) "Four Elephants", whose real name is Elk, is a rare animal in China. The origin of plants was 2.5 billion years ago.

It was not until 438 million years ago (Silurian) that green algae got rid of the shackles of water environment, landed on the earth for the first time, evolved into ferns, and clothed the earth with green clothes for the first time. 360 million years ago (Carboniferous), pteridophytes were extinct, replaced by lycopodium, wedge-shaped, true ferns and seed ferns, forming a swamp forest.

The main plants of Paleozoic were almost completely extinct 248 million years ago (Triassic), while gymnosperms began to rise and evolved pollen tubes, completely getting rid of the dependence on water and forming dense forests. Angiosperms (flowering plants) began to appear 1.45 million years ago (Cretaceous), and developed rapidly in the later period, replacing gymnosperms and forming the angiosperm era that continues to this day.

Modern types of pine, cypress, and even Metasequoia, Sequoia and so on. , are produced in this period. Characteristic plants have the ability of photosynthesis-that is, they can produce food by using water, minerals and carbon dioxide with the help of light energy and chlorophyll that animals do not have.

After releasing oxygen, glucose, an energy-rich substance, remains as a component of plant cells. Plants have obvious cell walls and nuclei, and the cell walls are composed of glucose polymer-cellulose.

The ancestors of all plants are single-celled non-photosynthetic organisms. They devour photosynthetic bacteria and form a mutually beneficial relationship: photosynthetic bacteria live in plant cells (the so-called endogenous phenomenon). Finally, bacteria become chloroplasts, which are organelles that exist in all plants but cannot survive independently.

Plants are usually inactive because they don't need to look for food. Most plants belong to angiosperms, which are flowering plants, including many kinds of trees.

The longest plants on land are in the tropical forests of Africa, where there are towering trees, exotic flowers and plants, and there are also "ghost ropes" that trip you. This is a white rattan wrapped around the tree for countless times. White rattan, also called provincial rattan, is also produced in Yunnan, China.

Rattan chair, rattan bed, rattan blue, rattan bookshelf, etc. Are made of rattan as raw materials. Rattan stems are usually very thin, as thick as a small handleless wine cup, and some are thinner.

It has a cluster of pinnate leaves at the top, and there are thorns on the leaves. The upper part of the stem is long and strong until the tip of the stem, and it is covered with large, pointed downward-bending spines.

Like a barbed whip, it swings with the wind. As soon as it touched the big tree, it clung to the trunk and soon grew a bunch of new leaves. Then it continued to climb along the trunk, while the leaves below gradually fell off.

After climbing to the top of the tree, the white rattan kept growing, but there was nothing to climb, so its longer and longer stems hung down, and the tree was regarded as a pillar and wound around it into countless strange circles. Rattan is 300 meters long from root to top, which is twice as long as the tallest eucalyptus in the world.

If the tallest tree holds the World Tree Height Competition, only Australian almond eucalyptus will be eligible to win the championship. Almond eucalyptus is generally as high as 100 m, and one tree is as high as 156 m. Its trunk soared into the sky, reaching 50 stories.

This is the tallest tree that man has ever measured. Birds are singing at the top of the tree, which sounds like the buzzing of mosquitoes under the tree.

This kind of tree is 30 meters long around the base, with straight trunk, obviously tapering upward, and dense branches and leaves at the top. The leaves are strange. Generally, the surface of a leaf is facing the sky, but its side is facing the sky, like hanging on a branch, parallel to the projection direction of sunlight.

This strange appearance is to adapt to the dry climate and strong sunshine, reduce direct sunlight and prevent excessive evaporation of water. The tallest broad-leaved trees in China-Wangtian Tree and Qingtian Tree. In the tropical dense forest of Xishuangbanna, Yunnan Province, China, a huge giant tree was discovered in the 1970s. Its graceful posture and tall trunk hold its head high above all the trees, making it impossible for people to look up at its top, and even the sensitive altimeter can't help here.

Therefore, people call it a tree looking up to heaven. The local Dai people call it an umbrella tree.

Looking up at the sky, trees can generally reach 60 meters. People have measured and analyzed a tree and found that it grows quite fast. A 70-year-old tree is 50 meters high.

Individual even as high as 80 meters, DBH is generally around 130 cm, up to 300 cm. These rare giant trees in the world stand in the upper layer of the valley rainforest, which is generally more than 20 meters higher than the trees on the second floor. They really have the momentum to go straight into the sky! Wangtianshu belongs to Dipterocarpaceae, Lu 'an.

Liu An belongs to this family, 1 1 members, and most of them live in Southeast Asia. Wangtianshu only grows in Yunnan, China, and is a rare and special tree species unique to China.

The tree is tall and straight, with alternate leaves, pinnate veins and yellow flowers arranged in panicles, emitting a fragrance. Its fruit is hard.

Cephalotaxus chinensis generally grows in 700- 1000 meters of valley rain forest and mountain rain forest, forming an independent community type and displaying a unique natural landscape. Therefore, the academic community regards it as a symbolic tree species of tropical rain forest.

Wangtianshu has excellent material, fast growth and high productivity. The trunk volume of a tree can reach 10.5 cubic meter, and the average annual growth of a single tree is 0.085 cubic meter, which is 2-3 times that of other tree species in the same forest. Therefore, it is an excellent tree species worth popularizing.

At the same time, its wood is rich in gum, its flowers contain perfume oil, and there are many other unknown components, which need further analysis and research.
