Schr? Dinger's cat is really popular, but many people still don't know what it means. Let's see what Schr? Dinger's cat metaphor is? Let's make it popular for you.
What does Schrodinger's cat mean
Schrodinger's cat means that if you don't do something, it may have two results. Once you do it, there will only be one final result, and your participation will directly interfere with the result.
For example, if you have a wife, you are not sure whether she loves you or not. At this time, there will only be two results in your mind, love or not. If you don't ask, these two results will always exist. In science, this is called "neither love nor love", which is corresponding to the state of both death and life in Schrodinger's cat.
Only if you ask, will there be results, but once you ask your wife, the result will be decided. This result is caused by the question you ask, that is, your question directly interferes with the result.
Schrodinger's cat was originally an experiment on quantum theory in an ideal state. It is assumed that a cat is put into a closed and opaque box. In the box, there is a poison bottle. The poison bottle and a radioactive nucleus constitute an ideal device. It is assumed that 50% of the nucleus may decay within an hour, and the device will trigger the device to open the poison when the nucleus decays Bottle, then you won't know if the cat is alive or dead without opening the box.
Schrodinger said: according to the explanation of quantum mechanics, the cat in the box is in the "dead live superposition state" -- both dead and alive. It's not until you open the box and have a look at the cat that decides whether it's alive or dead.
That is, the nucleus is in the superposition state of decay and non decay, then the cat is in the superposition state of living death. This makes the micro uncertainty of quantum mechanics into macro uncertainty, and the micro chaos into macro Absurdity -- the cat is either dead or alive, and it is impossible to live and die at the same time.
What does Schrodinger's cat mean
An ideal experiment proposed by Schrodinger. Put the cat in a box. When you open the box, you will randomly trigger a device to kill the cat. So the behavior of the observer will affect the result of the observation. One thing you don't care about, it's there. If you want to study it, the results will be influenced by yourself.
Einstein has a grandmother paradox, that is, if time can be reversed, a person killed his grandmother, so the development of sure no one was born, into another universe, this is called parallel universe. Will there be an infinite number of universes in this way? In fact, it is not. Because you go back and make changes to the universe, then the universe changes. If you don't go back, the universe, like this cat, is in a state that nobody knows.
The purpose of Schrodinger's cat is to prove that the micro world, like the macro world, is eternal. There is no time point when you start to observe it.
For example, everyone has played a coin toss. If you toss a coin only once, the result is uncertain. If you say that the result is certain, it is because there are only two results to choose, either positive or negative. I believe everyone knows that it is uncertain whether a coin toss is positive or negative. It is 50% possible for each coin toss The coin must be positive or negative, but in terms of 10 times, 100 times and 1000 times, the result of this throw is not important. If the coin is repeatedly tossed 100 times, the first reverse, the second positive, the third positive, the fourth positive, the fifth reverse & hellip; & hellip; If the observer does not observe from the first time, but observes the third and fourth times, the observer will be confused by the appearance, because the result of the third and fourth time makes the observer think that the coin toss is always positive. However, if the observer observes 100 million times, he will come to the conclusion that the result of the coin toss is uncertain, and the result does not depend on where the observer comes from If you don't observe it, there will always be two possible results. When used in the field of quantum mechanics, it means that the electron will move to multiple places when you don't observe.
To sum up: there is uncertainty in certainty and certainty in uncertainty. Don't be confused by observation.
