Find three examples of reverse thinking!

Case 1: Sima Guang smashed a jar and someone fell into the water. The conventional thinking mode is "saving people from water", but Sima Guang used reverse thinking in the face of emergency and danger, decisively smashed the jar with stones, "letting water leave people" and saved his friend's life. Case 2: The Generation of the Law of Electromagnetic Induction 1820 Oster, a professor of physics at Copenhagen University in Denmark, obtained the magnetic effect of current through many experiments. After this discovery spread to the European continent, it attracted many people to participate in the study of electromagnetism. Faraday, a British physicist, repeated Oster's experiment with great interest. Sure enough, as long as the wire is electrified, the magnetic needle near the wire will deflect immediately, and he is deeply attracted by this strange phenomenon. At that time, the dialectical thought in German classical philosophy had been introduced to Britain, and Faraday was influenced by it, thinking that there must be a connection between electricity and magnetism and they could be transformed into each other. He thinks that since electric energy produces a magnetic field, the magnetic field can also produce electricity. In order to realize this idea, he started the experiment of magnetic power generation from 182 1. N experiments have failed, but he firmly believes that the method of thinking in the opposite direction is correct and continues to adhere to this way of thinking. Ten years later, Faraday designed a new experiment. He inserted the bar magnet into a hollow cylinder wound with a wire, and the pointer on the galvanometer connected to both ends of the wire turned weakly! The current is generated! Later, he designed various experiments, such as the relative motion of two coils, and the change of magnetic force can also produce current. Faraday's ten years of unremitting efforts were not in vain. 183 1 year, he put forward the famous law of electromagnetic induction, and invented the world's first power generation device according to this law. Today, his laws are profoundly changing our lives. Faraday's successful discovery of the law of electromagnetic induction is a great victory in using the method of reverse thinking. Different from conventional thinking, reverse thinking is a reverse thinking problem, thinking in a way that most people have never thought of. Thinking and dealing with problems with reverse thinking is actually to achieve the goal of "winning by surprise". Therefore, the result of reverse thinking is often surprising, unexpected and rewarding.
