A small example of creative thinking?

Creative thinking is a pioneering thinking activity, that is, to open up new fields of human cognition and create new achievements of human cognition. Creative thinking requires people to pay hard mental work. The achievement of a kind of creative thinking is often achieved through long-term exploration, hard study and even repeated setbacks, and the ability of creative thinking is also acquired through long-term knowledge accumulation and quality tempering. As for the process of creative thinking, it is inseparable from various thinking activities such as reasoning, imagination, association and intuition.

Creative thinking has the following characteristics:

Creative thinking is novel, which is characterized by innovation, either in the choice of ideas, or in the skills of thinking, or in the conclusion of thinking. On the basis of predecessors and ordinary people, it has unprecedented originality, new insights, new discoveries and new breakthroughs, so it has a certain range of initiative and pioneering.

Creative thinking has great flexibility. It has no ready-made thinking methods and procedures to follow, and people can freely use their imagination.

Creative thinking has the characteristics of artistry and non-imitation, and its object is mostly "things themselves" rather than "things for me" There are two possibilities for the result of creative thinking.

Creative thinking has a very important role and significance. First of all, creative thinking can continuously increase the total amount of human knowledge; Secondly, creative thinking can continuously improve people's cognitive ability; Third, creative thinking can open up a new situation for practical activities. In addition, the success of creative thinking can also encourage people to further creative thinking. As Hua, a famous mathematician in China, said: "The value of' man' lies in his creative thinking."

The invention of knocking on wooden barrels, chest percussion and stethoscope is another achievement of developing thinking association activities by using the connection principle. The story goes like this: More than 300 years ago, an Austrian doctor treated a patient with chest disease. Because the stethoscope and X-ray fluoroscopy were not invented at that time, the doctor could not find out where the disease was, and the patient died. Later, after autopsy, it was learned that the deceased's chest was inflamed and suppurated, and there was a lot of water in the chest. As a result, the doctor blamed himself and decided to study the method of judging pleural effusion, but he couldn't figure it out for a long time. As it happens, the doctor's father is a shrewd wine merchant. His father can not only identify the quality of wine, but also estimate the amount of alcohol in the barrel without opening it. Inspired by his father's knocking on the bucket, the doctor thought, isn't a man's chest similar to a bucket? Since my father can judge how much wine is in the barrel by tapping it, if there is water in his chest, the tapping sound must be different from that of normal people. Later, when the doctor checked the patient's chest again, he knocked with his hand. By comparing the chest tapping sounds of many patients and normal people, he can finally diagnose whether the chest is sick from the tapping sounds of several parts. This diagnostic method is now called "percussion" in medicine.

Later, this "percussion" method was further developed. 186 1 one day, a French male doctor, Lake, was embarrassed when he saw a woman with heart disease. When he was in a dilemma, it suddenly occurred to him that he participated in children's games. The children scraped one end of a log with a needle, and the other end was close to the log with their ears. They could hear the scraping sound clearly. Inspired by this incident, he asked someone to take a piece of paper, roll it tightly into a cylinder, put one end on a woman's heart and the other end on his ear. Sure enough, he heard the patient's heart rate sound, even better than listening to the patient's chest directly with his ears. Later, according to this principle, he changed the roll paper into a small log, then changed it into a rubber tube, and the other end was improved into a small box that could be attached to the patient's chest, which became the current stethoscope.
