Another world conquest manual

Double slit interference.

This should be a relatively well-known piece of physics knowledge.

A long time ago, the physical world was divided into two schools of explanation for the form of light:

One group believes that light is a particle, and the other group believes that light is a wave.

As for the Dagu Sect that appeared later, I won’t mention it here.

At that time, both the wave and particle factions had sufficient evidence, and no one could convince the other.

Later, physicists thought of a way:

Use the double-slit interference experiment to determine whether it is a particle or a wave.

This experiment is actually very simple.

Double seams, as the name suggests.

Just cut two slits in a partition.

Then use a machine gun that emits photons to shoot at the double slits.

The photons leaking through the slit will leave a light spot when they hit the screen behind the slit.

Before the experiment, the experimenters made two guesses:

The first possibility.

If photons are pure particles, then the screen must leave two bars.

Photons, like those fired from a machine gun, will pass straight through the gap like bullets, so what is left on the screen must be two bars.

Because photons from other angles are blocked by the plate.

The second possibility is that if the photons are pure waves, then zebra-like stripes will be left on the screen.

Because when a photon passes through the slit, it will form two wave sources.

The two waves oscillate and interfere with each other, the intensity between the wave peaks is superimposed, and the positive and negative cancellations between the wave peaks and the wave troughs.

Eventually, complex and beautiful zebra crossings, also known as interference fringes, will appear on the screen.

Everyone should know the final result of this experiment, which verified the wave-particle duality of light.

This is actually a very, very hairy experiment.

Because its final conclusion is

The results of the experiment depend on whether you observe the photons!

What does this mean?

Give a very simple example that few students can understand.

There is a live football match on your TV, and a player takes a shot.

Pause here for now. Can you predict whether this ball will be scored?

In the eyes of fans, whether the ball is scored or not is related to whether the shooter is Cristiano Ronaldo or Messi, the state of the opponent's goalkeeper, and maybe whether the referee collects money.

According to scientists, there is more to it.

For example, the force, speed and direction of the ball, and the distance from the goal.

Even the friction of the turf, the decibel level of the fans’ roar, and so on.

As long as these factors are taken into account in the equation and calculated, the state of the ball three seconds later can be accurately predicted.

But whether you are a fan or a scientist, you should all agree on one thing:

Whether the ball goes in or not has absolutely nothing to do with at least one thing:

That's your TV.

No matter what brand of TV you use, no matter the screen size, resolution, quality, whether you are watching Migu or CCTV5

The goals that should be scored will still be scored, and the goals that should be scored will not be scored.

It doesn't matter if you get so angry that you smash the TV.

Do you think that all the above is nonsense?

So, listen carefully:

The double-slit interference experiment proves that under the same conditions, whether the ball goes in or not depends directly on whether you are watching TV or not at the moment of shooting!

Isn’t it scary?

Photons shoot from the emitter to the double slit, like a football shooting to the goal.

Using a camera to observe whether and how photons enter the crack is like watching a goal on a television.

You turned on the camera to observe photons (watching TV), and you turned on the camera (not watching TV) - the results of the two experiments were completely different.

This is the curse of the observer.

If you don’t look at a photon, it is just a wave. If you look at it, it instantly becomes a particle.

to be honest.

This thing really cannot be studied in depth at the moment. If we go deeper, we may even get into the difference between materialism and idealism.

It’s hard to say whether there are twenty local people who are truly qualified to be involved in this field and make authoritative voices.

It was precisely because of the wave-particle duality of light that Wang Qiang suddenly had a new idea:

Information is transmitted through interference of radio waves.

"Although we currently don't know the details of the divine mind, Mr. Liu's team has long determined that it is a wave."

At this time, Wang Qiang was explaining her thoughts to everyone:

"Clan Chief Wei's spiritual thoughts cannot be transmitted because the other end of his spiritual thoughts is connected to his pineal gland. Wherever his spiritual thoughts go and what he does are controlled by his thoughts.

In other words, he is an observer.

Since it is an observer, interference will inevitably occur.

On weekdays it's fine.

Comrade Cao Yi is currently refining his natal magic weapon, so naturally he cannot resist this kind of interference.

But we are different. We can send a self-propelled microwave without a carrier! "

Students who have studied physics must remember one word:

wavelength.

Wavelength does not mean the sausage between the waves, but refers to the distance between two adjacent wave crests or two wave troughs along the propagation direction of the wave.

Among various wave types, the wavelength of microwave is 1 meter to 1 millimeter.

That is if the conditions are right.

Emitting a section of microwave away from the terminal is as simple as pressing the remote control at home.

The rabbits don't even need to carry any information.

As long as the frequency of the wave source is adjusted to be consistent with the divine thoughts, the two sides will inevitably produce wave crest interference.

And this kind of interference is normal and harmless, which is completely different from the interference caused by divine thoughts.

It's almost like a stone dropped on the water causing ripples.

Cao Yi is like a fish at the bottom of the water. He will definitely react when he hears the sound of stones falling into the water.

After all, as a former front-line police officer, my reaction ability is definitely not slow.

As long as Cao Yi realizes that the main console has discovered his abnormality, he will 100% direct his spiritual thoughts towards the gate to refine the natal magic weapon.

Wang Qiang's proposal was quickly adopted, and relevant work was handed over to Liu Xiangqian's team for preparation.

ten minutes later.

A piece of FM equipment was transported to the main console, and Liu Xiangqian pressed the switch himself.

Then everyone turned their attention to the screen.

He held his breath and concentrated, expecting good news.

It took about a few minutes.

The lines representing divine thoughts on the screen suddenly began to change.

The picture displayed by the previous spiritual sensor was very clear:

Except for the soul-breaking sword, all the original spiritual thoughts were taken back into the body by Cao Yi.

And at this moment.

These spiritual thoughts suddenly began to radiate outward.

The whole body is 1.5 meters, the whole body is three meters, the whole body is five meters.

After that.

Outside the door!

at the same time.

In the training room.

Cao Yi's mood at this time was also quite unstable, and he was confused with the joy of surviving the disaster.

Before the microwave on the main console appeared, he had reached a state on the verge of physical limit.

The Broken Soul Sword was successfully refined a long time ago, but for some unknown reason, the spiritual thoughts in Cao Yi's mind were still surging.

It's not like Cao Yi has never tried to let go of his spiritual thoughts.

But the spiritual thought at this time is like a spring, it will automatically return if no extra mark is found.

And there will be feedback as long as you pull it.

Under the impact of a large amount of accumulated spiritual thoughts, his consciousness even became a little blurry for a while.

fortunately.

Just when Cao Yi was about to run out of oil and the lamp was dry.

A microwave appeared.

As Wang Qiang said, microwaves do not convey much information.

But the frequency of its vibrating waves is completely consistent with the divine thoughts, and the crest of the disturbed waves is clearly pointing towards the entrance.

Cao Yi quickly used his last bit of strength to direct his spiritual thoughts outside.

The released spiritual thoughts were attracted by the many core marks at the door, and they surged out uncontrollably like a flood that was close to bursting the embankment.

At this time, Cao Yi was close to a semi-conscious state and could only let his spiritual thoughts flow out, unable to control himself.

In a microscopic world invisible to the naked eye.

A large amount of spiritual thoughts poured out from the training room. At this time, there were nearly twenty natal magic weapons for the spiritual thoughts to choose from, but the spiritual thoughts were not as urgent as before.

Between confusion.

Cao Yi suddenly felt a big guy farther away.

Subconsciously, he used his last bit of strength to direct his thoughts in that direction.

Then the whole person leaned on the futon in the training room with some sluggishness.

at the same time.

Hua Jun suddenly said a curse word:

"Damn it, how did this kid refine the 59 Kai that I made?"
