Reflections on the story of Cao Chong elephants calling for 200 years.

What does this story of Cao Chong calling himself an elephant inspire you?

Inspiration: Be good at thinking and thinking when things happen.

"Cao Chong is an elephant" is a story almost known to women and children in China. Cao Chong, who is only six years old, solved a big problem that even many learned adults were at a loss by using the physical principle that the gravity of an object floating on the water is equal to the buoyancy of water on the object. This is a miracle.

In fact, the clever Cao Chong's method is "equal replacement method". Using many stones instead of elephants, marking on the ship's side, making elephants and stones have the same effect, weighing stones repeatedly, and transforming "big" into "small", this problem can be solved satisfactorily.

(1) Reflections on 200 stories of Cao Chong Statue Further reading: Equivalent replacement is a common scientific thinking method. This is another short story of Edison.

The great American inventor Edison had an assistant named Aptom, who had a good foundation in mathematics. Once, Edison gave Aptom the glass shell of a light bulb and asked him to calculate the volume of the light bulb.

Aptom looked at the pear-shaped bulb shell, thought for a long time, drew the sectional view and perspective view of the bulb shell, drew a series of complicated curves, measured the data one by one, and listed a series of formulas.

After several hours of intense calculation, the result hasn't come out yet. Edison was very dissatisfied after reading it. I saw Edison fill the bulb shell with water and then pour the water into the measuring cup. In less than a minute, he calculated the volume of the light bulb. Here, Edison replaced the volume of the bulb shell with the volume of water poured into the measuring cup, and also used the equivalent replacement method.

Second, an overview of the story of elephants in Cao Chong.

When Cao Chong was five or six years old, his knowledge and judgment had reached a level comparable to that of an adult (such as a junior college adult). When Sun Quan gave him an elephant, Cao Cao was very happy. Cao Cao wanted to know the weight of the elephant, so he asked his subordinates, but he couldn't say how to weigh it.

Cao Chong said: "Put the elephant on the big ship, mark where the water surface reaches, then let the ship carry other things (when the water surface reaches the mark), weigh these things, and then compare them (the total mass of things is almost equal to the mass of the elephant)." Cao Cao was very happy and did it at once.

(2) The story of the elephant in Cao Chong, after reading 200. Extended reading:

Introduction to Cao Chong:

Cao Chong (196-208), born in the late Eastern Han Dynasty, was a secretariat of Yuzhou (now Bozhou) in the Eastern Han Dynasty, the son of Cao Cao and Mrs. Huan.

Cao Cao boasted to his ministers several times, meaning that he should be the heir. Cao Chong died before he was a teenager, at the age of thirteen.

3. Enlightenment of Cao Chong's image reappearance.

This article aims at praising Cao Chong's extraordinary wisdom when he was young. Age is not the size, the key is to be good at observing and thinking, and children can do great things.

Cao Chong said:

Original text:

Cao Chongsheng is five or six years old and as smart as an adult. When Sun Quan tasted the elephant, Mao wanted to know its weight. It is impossible to be reasonable under the group he visited. Chong said, "If you set up an image on a ship, you can carve its water mark, call it, recite it, and then you can learn. If we call it another thing again, it will be known as "MAO Yue", that is, how to implement it. "

Translation:

When Cao Chong was five or six years old, his knowledge and judgment were comparable to those of an adult. Sun Quan sent a huge elephant. Cao Cao wanted to know the weight of the elephant and asked his subordinates, but all the ministers couldn't figure out how to weigh it. Cao Chong said: "Put the elephant on the big ship, mark the place where the water has not passed the ship, weigh the objects on the ship, and compare them to know the result." Cao Cao was very happy to hear this and immediately acted according to this method.

Story:

Once, Sun Quan of Wu gave Cao Cao an elephant, and Cao Cao was very happy. On the day when the elephant was transported to Xuchang, Cao Cao led the civil and military officials and his youngest son, Cao Chong, to see it.

Cao Cao's people have never seen an elephant. The elephant is tall and big, and its legs are as thick as the pillars of the hall. When people get closer, they can't reach its stomach. Cao Cao said to everyone, "This elephant is really big, but how much does it weigh?" Which one of you has a way to weigh it? " Hey! How can you call such a big guy? Ministers are talking about it.

One said, "just build a top scale."

The other said, "What a scale it needs! Besides, elephants are alive and there is no way to weigh them! I think we must kill it, cut it into pieces and weigh it. "

Hardly had he finished speaking when everyone burst out laughing. Someone said, "You can't do this. Isn't it a pity to kill an elephant alive in order to weigh it? "

Ministers tried many methods, but none of them worked. It's really embarrassing.

Then a child came out of the crowd and said to Cao Cao, "Father, I have a way to call an elephant."

Seeing that Cao Chong was his favorite son, Cao Cao smiled and said, "What can you do at a young age? Tell it to me and see if it makes sense. "

Cao Chong prone on cao cao ear, spoke softly. Hearing this, Cao Cao cheered again and again, ordered the left and right sides to prepare elephants at once, and then said to his ministers, "Go! Let's go to the river to see elephants! "

Ministers followed Cao Cao to the river. There was a big boat parked in the river, and Cao Chong had an elephant brought on board. When the ship was stabilized, a road was carved on the horizontal plane of the ship's side. Then let people take the elephant to the shore, put the stones, big and small, on the boat one by one, and the boat will sink bit by bit. When the hull sank to the same height as the water, Cao Chong told people to stop loading stones.

The ministers opened their eyes wide, but at first they didn't understand what was going on. When they saw this, they couldn't help exclaiming, "Good idea! Good idea! " Now, as we all know, just weigh all the stones on the boat and add up the weights, and you will know how heavy the elephant is.

Cao Cao was naturally happier. He squinted at his son and looked at the ministers proudly, as if to say to himself, "You are not as clever as my youngest son!" " "

"Cao Chong is an elephant" is a story almost known to women and children in China. Cao Chong, who is only six years old, solved a difficult problem by using the physical principle that the gravity of an object floating on the water is equal to the buoyancy of water on the object.

This is a miracle, and even many learned adults are at a loss. However, at that time (AD 200), although Archimedes principle had been discovered for 500 years, it was not until 1627 that this principle was introduced to China. It is impossible for George W. Cao Chong to know this truth, let alone the conditions of ups and downs.

In fact, the clever Cao Chong used the method of "equal replacement". Replace the elephant with many stones, mark the boat, make the elephant and the stone have the same effect, weigh the stones repeatedly, turn "big" into "small", divide and conquer, and this problem will be solved satisfactorily.

Equivalent substitution method is a common scientific thinking method. Here is a short story about Edison.

From the Three Kingdoms: Chong Shaocong Tea, born at the age of five or six, has the wisdom of an adult. At that time, Sun Quan once gave birth to a giant elephant, and Mao wanted to know its weight. It is impossible to be reasonable under the group he visited. Chong said, "Put it on a big ship, carve its water mark, weigh it, transport it, and you will know." Great joy, that is, how to implement it.

What story did Cao Chong tell when he called an elephant?

The story of the elephant in Cao Chong:

During the Three Kingdoms period, science and technology were underdeveloped, and there was no large-scale mechanical weighing equipment. At that time, when people needed to weigh a big and heavy thing, they would encounter a lot of trouble.

Cao Cao has a child named Cao Chong. Cao Chong was clever and witty from an early age.

Once, a foreign envoy paid tribute to an elephant. The elephant is huge and spectacular, and everyone wants to know how much it weighs. So someone suggested that we should find a way to weigh the elephant.

At that time, it was a very difficult thing. How do you call an elephant that big? You can't measure it by fragments. This worries these adults. Just when everyone was at a loss, Cao Chong happened to pass by. He asked what happened. It turns out that everyone wants to weigh the elephant.

So Cao Chong said to the adults, "I have a good way to weigh an elephant." . When the adults saw it, it turned out to be Cao Chong, the youngest son of Cao Cao. They muttered: adults can't think of anything. What can a child do?

Cao Chong heard what they said, but he didn't care. He stood in front of the adults and said loudly, Take the elephant to the river, find a big boat where the elephant can stand, and then take the elephant to the boat. When the elephant gets on the boat, it will sink a little. At this time, you draw a mark where the boat is flush with the water.

Finally, let the elephant down and start loading stones on the boat until the boat descends to the place just marked. Isn't the weight of the stone on the boat the weight of the elephant? "Cao Chong said, everyone looked at each other and began to discuss in a low voice. Finally, everyone unanimously praised Cao Chong as a clever boy. Using Cao Chong's method, they quickly weighed the elephant.

Enlightenment of Cao Chong's image-building.

The "image of Cao Chong" is not a blind name, but a thinking method of "equivalent substitution": two completely equal quantities can be substituted for each other.

If it is difficult to directly consider some mathematical problems, the original conditions or problems can be replaced by equivalent quantities, so as to find clues to solve the problems.

What does the story of the elephant in Cao Chong tell us?

The story of Cao Chong's image shows that Cao Chong is very clever and wise. He can analyze the contradictions of things in detail and is good at solving contradictions. He solved the problem that there was no weighbridge in ancient times with big stones, which shows the importance of people's thinking ability. According to the present statement, it is: "Technology is the primary productive force."

The story of the elephant in Cao Chong:

By the time Cao Chong, the son of Cao Cao, was five or six years old, his knowledge consciousness and judgment could be comparable to that of an adult. Sun Quan once sent a giant elephant. Cao Cao wanted to know the weight of the elephant, so he asked his subordinates, but he couldn't think of a way to weigh it. Cao Chong said: "Put the elephant on the big ship, mark where it reaches the surface of the water, and then let the ship load other things to weigh, and compare them to know the result." Cao Cao was very happy and did it at once.

Cao Chong said 50 words after watching the elephant.

We are all familiar with the story "Cao Chong called an elephant". Clever Cao Chong first caught the elephant on the boat, observed the place where the boat was submerged by the river, and then carved a mark. Drive the elephant ashore and load the boat with stones. When the ship sinks into the marked position, it can be judged that the elephant weighs as much as the stones on the ship. Why can the weight of an elephant be replaced by the weight of a boat full of stones? Because two ships are submerged in the same depth after sinking, only the elephant is as heavy as a ship's stone (the weight is equal) will be submerged in the same depth.

Cao Chong's "image representation" is not blind, but uses the thinking method of "equivalent substitution": two completely equal quantities can replace each other. This story gives us an inspiration: if it is difficult to directly consider some mathematical problems, we can replace the original conditions or problems with equivalent quantities, so as to find clues to solve them.

Cao Chong's Elephant Story Write the main idea of the story in simple words.

Cao Chong first put the elephant on the big boat, then marked the place where the water arrived, then let the boat carry other things, weighed these things, and finally compared them to know the weight of the elephant.

When Cao Chong was five or six years old, he was as knowledgeable and judgmental as an adult. Once, Sun Quan sent a giant elephant. Cao Cao wanted to know the weight of the elephant, so he asked his men, but they didn't know how to weigh it.

Cao Chong said: "Put the elephant on the big ship, mark where it reaches the water surface, and then let the ship carry other things, weigh them and compare them." Cao Cao was very happy and did it at once.
