Ten logical problems in the world
1. Tram problem
2. cows in the open space
3. Einstein's Light
4. Lucretius's spear
5. Theseus' ship
6. Galileo's gravity experiment
7.monkeys and typewriters
8. Schrodinger's cat
9. Chinese style room
10. The brain in the jar
10. Tanqueray's brain This is an imaginative topic. If your brain is taken out and put into a life-sustaining liquid, electrodes are inserted into your brain, and then images and signals will appear on the computer to get information from your brain. In other words, this computer imitates your daily life. This experiment contains knowledge and philosophy, which is puzzling. If the experimental results come true, how can you prove that the world in your daily life is real?
Nine, the Chinese room Chinese room This was put forward by the American philosopher John Searle. This experiment is to make you imagine that you are in a room except for a hole in the door. All the rooms are closed. If you only bring translation books, pencils, manuscript paper and cabinets, outsiders will write small notes in Chinese and then reply with these translation books, so that outsiders will feel that their Chinese level is very good.
Eight, Schrodinger's cat Schrodinger's cat was put forward by physicist Schrodinger and talked about quantum mechanics. A cat was put in a closed box with radioactive poison gas in it. After an hour, the radioactive poison gas gradually decreases, and then the hammer connected to the Geiger counter will be triggered to break the bottle and continue to release the poison gas to kill the cat. The probability of this experiment is equal. He thought that if the box was opened, the cat might be dead or alive.
Monkey and Typewriter Monkey and Typewriter This is a thought experiment, that is, the infinite monkey theorem is called one of the top ten logical problems in the world. Countless monkeys can type on countless typewriters for a long time, so this monkey can certainly type all Shakespeare's literary works. This problem occurred in the 20th century and was put forward by the French mathematician Emile. This is just a hypothesis. No one knows whether the monkey can finish it.
Six, Galileo's gravity experiment Galileo's gravity experiment This is also a relatively simple thought experiment, depending on the mass theory of objects. If you tie a light object to a heavy object and put it on a high place and drop it together, the heavy object will definitely fall fast and the light object will definitely fall slowly. But from another point of view, the mass of two objects falling together should be greater than that of any single object, and the falling speed should be faster. It seems a bit contradictory, but this theory is wrong.
The ship of Theseus is the oldest ideological problem among the top ten logical problems in the world. According to Plutarch's records, a ship that has been sailing at sea for hundreds of years, after a long time of repair and replacement, some boards have rotted. According to this, all parts must be replaced. So the question is, is it a completely different ship or the original ship after replacement? When is it no longer an old ship? Philosophers think that if a new ship is rebuilt according to the old part, which of the two ships is the original theseus ship?
Fourth, Lucretius's spear Lucretius's spear is also a difficult logical problem. How can you prove that the universe is infinite without giving you any tools? Roman philosopher Lucretius said that the universe is limited. In the end, throwing a spear will only produce two results, that is, something blocks it and the second one bounces back. This is just an illusion of human beings. In fact, there is no difference between finite and infinite. Like a sphere, you can't see its starting point and ending point.
Einstein's Light Einstein's light was a thought experiment when he was 16 years old. It is said that he imagined himself running with the light of the universe and felt that he could move beside the light at the speed of light. Then he should be able to see that light is constantly turbulent in space, but the electromagnetic field is stopped. This thought experiment proves that this is just a virtual observation. If it is stipulated that the laws of physics must be the same as those seen by the exquisite observer relative to the earth.
Second, the title of the open field cow is like this. A farmer is worried that his cow will get lost when he wins the prize. At this time, the milkman told him not to worry about your cows grazing in the open space. Finally, the milkman came in and saw the cow hiding in the forest. There is a piece of kraft paper hanging on the tree. It turns out that everyone thinks this piece of paper is a cow, so the problem comes. But the farmer said he knew the cow was in the clearing. Is this correct?
First, the tram problem The tram problem is a well-known thought experiment. A madman tied five innocent people to the tram track, and the tram could directly crush them. But it is said that you can pull a lever to drive the tram to another track, but the other track is also tied by this madman. Can you pull the lever? This problem is one of the top ten logical problems in the world, which makes people puzzled!
Conclusion: The above are the top ten logical problems in the world that I have listed for you. These thoughtful questions give us unlimited room for daydreaming. I really admire the brains of those philosophers!
