How did you, a prisoner on death row, become an important weapon of the country? Yecheng Gao Weiming

When they entered the King of Clubs challenge card and heard the prompt sound, everyone was stunned.

Although I was mentally prepared, I was still shocked by the sound in my ears.

really!

It is indeed one of the four great beasts of physics.

The one that was raised by old man Schrödinger himself, and has been discussed by the entire physics community for nearly a hundred years, but has not yet been completely solved...

Cat!

A powerful and fascinating Schrödinger's cat!

And what is Schrödinger's cat?

Although it may sound a bit old-fashioned, I still want to repeat it again and again.

This is a classic paradox proposed by Austrian physicist Erwin Schrödinger in 19 to counter the Copenhagen School.

At that time, due to disputes over the study of quantum mechanics, two major schools of thought were born in the physics community: the classical school of physics and the Copenhagen school of physics.

The classical school of physics is headed by Einstein and Schrödinger.

They believe that in the microscopic world, that is, quantum mechanics, everything is determined.

Its operation should follow the three laws proposed by Isaac Newton, and the basis of all research should also comply with the three laws, emphasizing certainty, regularity and scientificity.

Even Einstein once famously said this.

God never plays dice.

This shows that there are corresponding laws in the microscopic world, and everything has a traceable path.

But the Copenhagen School clearly disagrees with this statement.

Led by Bohr, Heisenberg and others, it proposed the principle of complementarity and the principle of uncertainty.

They believe that in the quantum world, everything is full of uncertainty and there is no track to follow.

It is just like the wave-particle duality of microscopic matter. When you observe the microscopic world, it is a wave, and when you don't observe it, it collapses into particles.

No one can tell clearly whether it is a wave or a particle. We can only say that microscopic matter is constantly entangled, superimposed, and collapsed between waves and particles.

Only when people observe it will it determine its final form.

To sum up, the view of the Copenhagen School is.

Material changes in the microscopic world are full of uncertainty. As long as they are observed, wave function collapse will occur, which is subject to human will.

The classical physics school certainly did not agree with this view, and a heated debate ensued between the two sides.

What the hell are you talking about?

This is science, extremely serious science, how can there be uncertainty?

at this time.

Mr. Xue, also known as Mr. Schrödinger of the classical physics school, finally couldn't help but use his ultimate move.

The microscopic world is full of uncertainty?

Row!

Then let me put forward a hypothesis and see how you, the Copenhagen School, would answer this question.

It is said that a cute kitten is put in a sealable box.

At the same time, a Geiger counter, a device for measuring radiation, was placed in the box.

After installing the Geiger counter, we put in a small amount of radium, a hammer, and a gas bottle filled with cyanide.

Finally, the box containing the kitten was closed and the experiment began.

A small amount of radium put in before will decay within a certain period of time, then radiation will be generated and the Geiger counter will detect it immediately.

Once radiation is detected, the mounted hammer will immediately smash the glass bottle containing cyanide.

If cyanide leaks, the highly toxic substances produced will kill the kitten instantly.

Then the problem is coming.

Before we opened the box, was the kitten inside dead or alive?

According to the concept of classical physics.

It must have only one state.

Either die or live.

Whether you open the box or not, there is no third scenario.

But if we use the Copenhagen School's words, it is.

There is a third state for the kitten in the box.

It is a superposition state of both dead and alive!

Regardless of whether the radium decays as soon as the box is sealed, or whether the radium never decays and cyanide is never produced, the kitten is in a superposition state of being both dead and alive.

Only when the observer opens the box will the kitten be determined to be dead or alive!

This completely subverts everyone's cognition.

What a fucking joke!

How could a cat that is both dead and alive exist in the world? How could a living being be in a state of uncertainty?

The purpose of Mr. Xue's proposing this paradox is to mock the Copenhagen School.

You are violating the basic laws of physics and you are challenging the seriousness and rigor of science.

You are destined to be laughed at for eternity and be mocked by future generations.

who knows.

The Copenhagen School shamelessly admitted it.

Not bad!

According to our theory, before the box is opened, the cat you raised is in a superposition state of both dead and alive.

When it is alive, it also represents death, and when it is dead, it also represents survival, just like the wave-particle duality that is constantly entangled, collapsed, and superimposed...

Only when we observe it can we determine its final form.

And how to observe?

You can open the lid of the box, or you can lean outside the box to listen to what's going on inside, or you can even use all the technical means to observe through the box.

Just observe and it will determine the final form.

Speaking of this, some netizens joked.

Do you think Schrödinger's cat is dumb? Shouldn't it meow a few times whether it is dead or not?

Raising this question shows that one does not understand the microscopic aspects of quantum mechanics.

According to the definition of physics.

As long as the cat meows, the observer can be considered to have observed the cat's survival status.

So when the cat's meowing sound is made for the first time, we can determine whether it is dead or alive.

Is it difficult to understand?

Not difficult.

With the help of instruments and calculations, humans can observe the shapes of planets 137 billion light-years away.

But what about 137 billion light years away?

What state is it in?

How do you know whether it is a wave or a particle, whether it exists or disappears, just by imagination and reasoning?

Only when our science and technology improves and we can observe farther distances can we confirm our inferences.

This is similar to Schrödinger's cat.

When we are not observing it, it may be in a state of both dead and alive.

You can't arbitrarily say that it is dead or that it is alive.

Because you can't observe it.

and so.

When Mr. Xue proposed the paradox originally intended to mock the Copenhagen School, he unexpectedly succeeded in doing so.

Unexpectedly, this paradox led to the establishment of the Copenhagen School.

Proven by years of scientific experiments and exploration.

In the microscopic world, all matter does exist in entanglement, superposition, and uncertainty.

As long as we humans observe it, it will produce wave function collapse.

As long as our science and technology or knowledge has not reached a certain level, we can only think.

The entire quantum world, or the microscopic world, is full of uncertainty.

Although due to human cognitive problems, it is still impossible to confirm whether the classical physics school or the Copenhagen school won the debate.

But the uncertainty of the microscopic world has gradually become mainstream cognition.

Who is right and who is wrong remains to be confirmed by future generations.

Having said all this, you should have a general understanding of what Schrödinger's cat is.

And everyone in the Clubs King Challenge Card finally began to listen to the challenge rules.
