Schrödinger's Cat

Schrodinger's cat experiment, which has a precondition, is a random triggering device that conforms to quantum mechanics.

In a closed box, there was a cat, and a device full of gas. The device has a 50% probability of opening, if turned on, the gas inside the device will kill the cat in the box.

OK, now back to this precondition, is the randomness of the device. This 50% probability, is not simple to cast a coin, 50% chance of positive, 50% chance reverse is so easy. If you just cast a coin, then you throw the force, the angle, the speed of the rotation of the coin, the air resistance, the aerodynamic force generated by the rotation of the coin, even the molecular division on the surface of the coin, the earth to the tilt of the force, any small data all concentrated together, after a huge calculation, Then in the moment the coin throws out, get the result is already doomed, there is no so-called 50% randomness can say.

We can understand that all the data thrown in the coin is observed in the universe, so the universe knows whether the device will spray the poison, in other words, the cat in the box cannot be "quantized".

The core of the experiment is not the box, nor the cat, but the real "random" device that can be produced. The principle is that the half-life of radioactive elements is unpredictable. The organ is controlled by a radioactive atom, and its fission triggers the organ. This device captures random numbers that the universe cannot observe and calculates, and, based on the results of random numbers, has a 50% chance of releasing the gas.

Under this precondition, when the box is closed, the cat will be in the superimposed state of being alive and dead. Because even the universe does not know whether the cat in the box is alive or dead.

After that, we humans are part of the universe. As we open the box, we act as the "observer" of the universe. When we opened the box, the cat that was in the superposition state of life and death would be observed by the universe through our eyes. When the "observer" is present, the "probability cloud" that originally wraps the cat will collapse. According to the device, if the device sprays the poison gas, then the cat's "Live cat" portion of the superimposed state will collapse with the probability cloud, and we will only see the dead cat. Conversely, if the device does not inject poison gas, then the "Dead cat" will collapse, we will observe a living cat.

In addition, why is the cat not part of the universe?

First, the cat is enclosed in a box, and the random device in the box will turn its life and death around.

So the cat itself will be wrapped in a "probability cloud". In other words, the cat is living and dying together. This overlay cannot be observed with each other. Superimposed state of the "Live Cat" section, thinking that he has been alive. The "Dead cat" part only knew the gas injection, and then became a corpse. The

can also understand that a "device sprayed the poison gas", and "a device without jet gas" of the two parallel worlds, in the box intersection. When the box was opened, one of the parallel worlds collapsed under the observation of the universe.

This is also the charm of quantum mechanics, the phenomenon of the micro-world, in the macro-world projection to the "cat" body, is so strange, tangled, and unbelievable.

Let's talk about the "Observer" section briefly.

I received some questions about why the cat could not observe himself, and found that it seemed to me that the example I gave to the explanation was not good enough.

Well, let me explain it again.

Back in the box, there was still a poor kitten, and a random device. The device is no longer connected to a gas bottle, but is connected to a nozzle filled with water. The radioactive atoms in the device fission, triggering the organ, the sprinkler will spray water to the cat body.

Then we closed the box and waited patiently.

In this case, there will be a dry cat and wet cat overlay. Dry cats and wet cats cannot observe each other.

The "Dry Cat" section, its experience is that the foolish man in a box, after a period of time, the box opened, it was very impatient to jump out.

The "Wet Cat" part, its experience is, by the foolish human to put in a box, the box is closed, the sprinkler spray water, will get wet. When the box was opened, it jumped out angrily, trying to get rid of the fur.

There is only one cat in a box, the box opens, and in our observation, one of them collapses with the probability cloud.
So, only one cat jumps out.

As to whether the cat is a dry cat or a wet cat, how do I know that the device will give a result, even the "universe" can not be predicted.

In short, it is one of the above two cats, in their experience, do not know the existence of another cat.

Therefore, the Cat cannot act as an "observer".
