In the past, some of my diary habits have been delayed, but I cannot help it. Now I am in a bad mood. I want to share a new one here.ArticleTo ease yourself!

How many buckets of water does the king's pool have? -Intelligence King story

Once upon a time, a wise king, accompanied by ministers, came to the royal garden for a walk. The king looked at the pool in front of him and suddenly burst into a whim. With a brainwave, the king made a question and asked the Minister around him: "How many buckets of water are there in the pool ?" As soon as the ministers heard it, they couldn't answer the question. The King sent a message: "I want to give you three days to think about it. Whoever answers it will be rewarded !"
How do you answer the question from smart readers? Please refer to the below pool. This pool was originally part of the Yuan mingyuan Park. Together with huxin island, it is called NEAR Spring Garden. Now it is part of Tsinghua University. Is it beautiful? Think about how many buckets of water are there in such a pool?

If you cannot answer the question, proceed with the next step.

The ministers use the bucket volume to produce a specific amount of data. Three days later, the ministers are still unable to cope. At this time, a teenager went to the palace and claimed to the king that he knew how many buckets of water were in the pond. The king ordered the sweaty Ministers to take the teenagers to the pond. The teenager smiled with ease: "You don't have to read it. This problem is too easy !" King happy: "Oh, let's talk about it ." The teenager blinked and said, "The key to this problem is the size of the bucket. If the bucket is as big as the pool, it is a bucket of water. If the bucket is only half the size of the pool, there will be two buckets of water in the pool; if the bucket is only 1/3 large, there will be three buckets of water in the pool; if ......" "Okay, exactly !" The king rewarded the teenager.

The general story is complete here, and everyone must understand it. You may not understand. Please answer my questions:
Why can Teenagers come up with such an answer?
How can I solve a similar problem next time?
What methods and habits can we solve such problems?
Can you answer this question?

I will help you solve these problems. I hope this article will inspire you.
Here I want to introduce a method of thinking, called the question breaking method. This method is very practical for analyzing such questions and solving their learning problems.
The question breaking has two meanings:

First, break the "curse ";
The second is anatomy.
Let's first look at the obstacles to solving the problem.
Picasso said: "Before creation, we must first break it down ."
What do we get rid? Break the path dependency of thinking and break through the limitations of traditional ideas. In our traditional thinking, what is bucket? You must have thought of a bucket or TV barrel at home. Right? This curse locks you all at once!

We need to break all the secrets!
Let's look at how to dissect the problem.
The most important thing to break down is to break through the common problems in our daily life, and find problems from no problems.
When we look at things, we will always forget the relativity of things. It is often limited to a certain angle that cannot be drilled out without seeing the other side. If we change the angle, we can see the sky at once!
Therefore, we need to break down the question when analyzing the problem.
To solve the problem, you need to do the following:
First, stop at the moment.
For example, in the story above, when the king gave a question to the Ministers, the ministers did not analyze the question well, but were anxious to solve the problem quickly. Q: How can I answer the question if I cannot see it clearly?
Many students are very impetuous (this is the case for adults, but the degree is different). The most typical manifestation is that they cannot settle down. They are always thinking about moving forward. If they don't get a question, they want to see it quickly. When they see the question, they want to solve the problem quickly. When they solve the problem, they have not been able to solve it, and they have already gone out to play, when I went out to play, I was worried about my homework and learning.
Security is the most critical issue. This problem cannot be solved, and everything in your life cannot be solved.
The second is to crack every keyword in the problem.
In the story above, after the king asks a question, a wise person should first consider the following questions about the king:
First, how big is the bucket? The size of a bucket is vague.
Second, how much water is there? Obviously, the amount of water in the pool is vague. Second, determine the amount of water.

The above is fuzzy, so it cannot be determined. To judge, you should first determine the size of the bucket and the size of the pool.
So here, the problem is very clear.
In this analysis, will the answer come out?

So, to what extent do general learning problems need to be solved?
To the following extent:
First, the extent to which the principle is cracked;
Second, the extent to which the basic assumptions are cracked;
Third, the extent to which the attack reaches basic knowledge.

Here, the problem can be solved.

What are the corners of the King's table? -Intelligence King Story 2
Scientific Thinking TANG Zeng lei
The wise king, accompanied by the Ministers, came to the royal garden for a walk. When the King saw a rectangular table, he suddenly burst into a whim and made a smart move. He asked the Minister around him a question: "There are four corners of a table, each cutting a corner, and how many corners are there ?" As many ministers heard it, the question was easy. Their Science and Technology Minister was a doctor of mathematics and blurted out: "three !"
"No !" Someone immediately opposed it. As you may see, it turned out to be the prime minister of the financial industry. He was a turtle from Harvard Business School. "Five should be the prime minister ."
"High! It's really high !" Many ministers compete to settle this God of Wealth!
Then the king said, "Who has other answers ?"
In this case, the ministers did not answer the question.
The King sent a message: "I want to give you three days to think about it. Whoever answers it will be rewarded !"
Do you think of smart readers?

When the teenager came back and saw the king, he said, "There are at least three answers. Please see, if you cut a corner by line, there are five corners left. If you press the dotted line, there are 4 left. If you press the arrow, there are 3 left."

The king enjoyed the young man again.

This time, the Ministers learned well. They asked the teenager, "How can you get older than us? Thoughtful ?"
The teenager said with a smile: "The last time I asked laotang to tell you how to solve the problem, you didn't listen carefully and thought there was nothing to do with this method. This time, of course, we still use this method ."
At the same requirements of the ministers, the young man analyzed the issue.
The key to this problem is where to perform the removal. Selecting the location of the removal determines the number of remaining corners. However, in our minds, we only think that cutting an angle is to cut it by the solid line. In fact, the location can be changed at any time. In addition, there are more answers to this question.
"Are there more answers? Are there all three answers ?" The Ministers are curious again.
Of course not all! Just now I only considered the position of the table, not the knife. What if the knife itself has a horn? For example, if the blade of a knife is in a sawtooth shape, how many sertices are generated. Therefore, the answer is actually uncertain.

Also, how can you cut off only one angle? If the knife is straight, you should cut off at least three corners. I will not expand them here.
