The method of transforming reverse thinking refers to the way of thinking that when studying a problem, because the means of solving the problem is blocked, it is transformed into another means, or the angle of thinking is changed, so as to solve the problem smoothly.
A long time ago, shoes were not invented, so people were barefoot, even in the ice and snow. The king of a country likes hunting. He often goes out hunting, but he rides in and out and never walks. Once he walked a short distance while hunting, but unfortunately, his foot was pricked by a thorn. He screamed in pain and cursed the attendants around him. The next day, he ordered a minister that all the streets and alleys in the city must be covered with fur within a week. If it is not finished on time, the minister will be hanged. Hearing the king's orders, the minister was very surprised. But how can the king's orders not be carried out? He had to do it with all his might. Ministers give orders to their subordinate officials, who in turn give orders to the craftsmen below. Soon, the work of spreading fur on the street began, with great momentum.
There was a problem with the shop, and all the fur was used up quickly. Therefore, animals should be slaughtered every day. Thousands of animals were killed in succession, but less than 1% of the paved streets were paved.
Only two days before the deadline, the minister has lost a lot of weight. The minister has a very clever daughter. She said to her father, "I'll take care of this."
The minister smiled a few times and said nothing. But the girl insisted on helping her father solve the problem. She asked her father for two skins and made two leather pockets according to the shape of her feet. The next day, the girl asked her father to take her to the king. When she arrived at the palace, the girl first visited all hail the king and then said, "Your Majesty, we have finished all your tasks. You can put these two purses on your feet and go anywhere. Don't say small thorns, even nails can't penetrate your feet! "
The king put two purses on his feet and walked on the ground. He was surprised by the cleverness of the girl, and it was very comfortable to walk in these two leather bags. The king ordered all the furs on the street to be uncovered. Soon, the exposed fur piled up into a mountain, and people made thousands of pairs of shoes with them and came up with many different styles. Many people are trapped by the problem and can't find a solution. In fact, if we can look at the problem from another angle, sometimes a seemingly difficult problem can be easily solved by clever methods. This requires us to cultivate this multi-angle ability in our life.
Negative verification: Everything has its negative side. Which side do you see?
Some things are mutually causal, and from this aspect, we can explore another opposite aspect.
It is said that Einstein designed an intelligence test. A businessman wants to hire a capable assistant. He thought of a test method to select the smartest person from the two applicants.
Assistant.
He let A and B enter an empty room with no windows except a box on the ground. The businessman pointed to the box and said to the two men, "Here are five hats, two are red and three are black. Now I turn off the light, and the three of us each take out a hat from the box and put it on our heads. After putting on your hat and turning on the light, you should tell the color of your hat quickly. " When the light was turned on, both of them saw the businessman wearing a red hat on his head. They looked at each other for a while and hesitated to say what color the hat was on his head.
Suddenly, B shouted, "I'm wearing a black hat!" " "Why? The businessman has a red hat on his head, so there is only one red hat and three black hats left. When B saw A, he hesitated to tell the answer at once, so he decided that he was wearing a black hat. Because if B has a red hat on his head, A will immediately say that he has a black hat on his head. How could he hesitate?
B suppose you wear a red hat on your head, but you find the other person hesitating, so you get the answer.
This kind of reasoning is the reverse thinking of pushing forward from the result, and this method also plays an important role in invention and creation.
1877 One day in August, Edison, a great American inventor, tried to debug telephone transmission.
Microphone, when testing the vibration of communication membrane with short needle, I accidentally found one.
A strange phenomenon: as soon as the needle in your hand touches the sound film, the sound film will vibrate regularly with the change of sound intensity from the mobile phone. This strange phenomenon caused him to think. He thought: if the needle vibrates in the same way, the sound can be restored and the human voice can be stored. Along this line of thought, Edison set out to experiment. After four days and four nights of hard work, he finished the design of the phonograph. Shortly after Edison gave the designed drawings to the mechanic Crouch, a simple phonograph was made. Edison also publicly demonstrated. While shaking the iron handle with his hand, he sang to Jane, "Mary has a lamb, and its wool is Bai Rushuang." Then Edison stopped and had his ear pressed against the receiver. He put the needle back in its original position and shook the handle again. At this moment, the song just now sounded in the man's ear. Amazing. Newspapers have published articles praising this as another great creation after Bell invented the telephone, and another miracle in the19th century. Edison's success lies in his idea that the sound intensity changes to make the sound film vibrate regularly. If the needle vibrates in the opposite direction, the sound can be restored, so the sound can be stored! The invention of the phonograph,
In fact, this is a mutually causal negative verification method. When we encounter the same situation, we can try to deduce the cause and effect from the opposite side, and maybe there will be similar creative results.
