I have a full-time hero system

If the two are in opposite directions, then the speed of light should be C+V.

No one in the room objected to the inferences made here.

Isn't this a very simple application.

Froz also nodded.

The rest of the physicists took out their papers and wrote something.

"The problem is that we now know that the speed of light is 30 kilometers per second," Yuan Xiao pulled his hands apart, "If you measure the speed of light directly, let alone the error, I am afraid that if you want to get an accurate value, it may require a huge equipment to make it happen.”

This is where the trouble starts.

C is equal to 30 kilometers, and the V of relative motion needs at least a certain value before it can be measured.

Otherwise, even if there is a difference between the value of C+V and the value of CV, it is impossible to identify whether it is an experimental error.

This is where physicists such as Froz find it difficult.

The principle is simple, but it is difficult to implement.

"However," Yuan Xiao smiled, "We can use other relative speeds to improve part of the accuracy.

Here I have a clever experimental method, everyone looks at the screen. "

The PPT switches, and a schematic diagram comes out.

"Assuming that the ether exists, then everyone knows that our planet Bruya is revolving," Yuan Xiao reminded, "and the speed of this revolving is about 30 kilometers per second."

The students were still silent, and Froz was the first to stand up.

"Why didn't I think of it!" His tone was a little excited.

The other physicists were also stunned for a moment, then nodded frequently.

This is indeed the most immediate relative velocity available.

"Professor Froz's excitement, I understand very well," Yuan Xiao continued, "but give me a little time to explain the whole experiment clearly."

Froz looked cautious, and he sat down and took out his notebook to write something.

If it was said that he still had arrogance and prejudice towards Yuan Xiao, it would have disappeared completely by now.

"Then, when our planet is revolving, it must be moving against the ether, which will cause a difference of plus or minus 30 kilometers per second to the speed of light," Yuan Xiao pointed to the screen, "Compared to the speed of light, this speed is not enough. Calculate fast.

However, whenever there is a difference, we can detect it.

Here, the interference between the speed of light should be used. "

Yuan Xiao paused here for a moment, allowing the physicists to digest the relevant information.

It is very difficult to measure directly, but using the known relative speed difference and the interference of light waves, if there is a real speed difference, the interference fringe movement after interference can be calculated.

In this way, it can be confirmed whether the ether affects the speed of light.

"As you can see in this schematic diagram of the equipment," Yuan Xiao pointed to the picture, "This is a cantilever that is perpendicular to each other.

In the center of the cantilever, there is a light source, a half mirror, and an interferometer.

In this way, the light source produces light and shoots to the beam splitter, and the beam splitter divides the light into two mutually perpendicular rays.

Then use a total reflection mirror to reflect it back.

Finally, it enters the interferometer to generate an interference pattern.

That's how the device basically works. "

The students don't understand it yet, but the physicists understand it vaguely.

One by one couldn't help whispering.

Froz also nodded frequently.

This is indeed a very clever method.

After the light from the light source is divided into two perpendicular to each other, the distance they reflect back is the same.

If the speed of light does not change, the two beams of light reach the interferometer at the same time, and the interferometer can detect the wavelength of the two beams of light after interference.

If the speed of light of the two beams of light changes, and the time it takes to reach the interferometer is different, the interference fringes will shift.

In this way, the wavelength change of light after interference becomes clear.

Yuan Xiao glanced at the audience: "My personal calculation results, if the speed of light is inconsistent, then there will be a wavelength change of 0.04 times before and after."

Such a calculation is not difficult, the data is already available, Yuan Xiao just finished speaking, and other physicists also got a consistent answer.

Froz sighed: "That's true."

On the contrary, if the speed of light is constant, no matter when and where it is measured, the wavelength after interference will not change.

Yuan Xiao put the laser pointer on the podium, and he supported the podium with both hands: "Yes, through this method, we can know whether the speed of light has a speed relative to the ether.

That is to say, whether the ether exists can be checked out.

This is how I verify the existence of ether. "

As soon as this sentence was said, the get out of class bell rang.

As usual, Yuan Xiao would not delay class, he packed his things and prepared to leave.

This time not only the students, but even the physics professors quit.

What is this? It's broken again here.

We are all itchy.

A large group of people surrounded it, and it was completely blocked.

Froz was also sweating profusely: "Mr. Yuan, have you already done the experiment you proposed?"

"That's right, Teacher Yuan, let me tell you about the result."

"Don't worry about get out of class, we can continue to listen to you."

Yuan Xiao smiled: "That's not good, it's not good to affect the normal curriculum of the school.

Well, I heard that the open class is not limited to this one session, let's talk about it tomorrow. "

Tomorrow, tomorrow peat.

Don't want to wait for 1 minute!

Chapter 397 Experimental Test

No matter what, the school arranged for the students to leave first, and then invited them to the conference room.

Today, apart from physicists from all over the world, there are also leaders from the Ministry of Education and the Ministry of Science and Technology of the Principality. Some things have to be handled behind closed doors.

Ferreia was the first to speak: "There are some people who are at the top of the physics world here, so I won't be polite.

I am the president of a national university, but I consider myself a layman for in-depth research in the field of physics, and I still need to ask for your opinions. "

Yuan Xiao just smiled, it is understandable for the school and the leaders to be cautious.

The publication of new academics is not a joke, especially if there is such a big movement, if something goes wrong, it will be a shameful thing.

Physicists focused their attention on Froz, after all, he was the one who discovered the original equation.

Froz said: "Teacher Yuanxiao's experimental method, I just calculated it, and the result is consistent with Teacher Yuanxiao's.

So I personally think that the whole experiment is not a problem. "

Other physicists agree.

The leaders breathed a sigh of relief.

They also don't understand the theory of physics, and the leaders from the Ministry of Science and Technology are not experts.

There are specializations in the art industry, and this is the truth.

Yuan Xiao's identity is sensitive, he is only a teacher of high school students, and there are many opinions to be questioned.

The more this is the case, the more cautious you must be.

Now that so many experts are sure, there should be no problem.

"The verification of the experiment must be carried out immediately," Froz suggested, "in this way, Teacher Yuan's theory can be proved to the greatest extent."

Up to now, he is very convinced of Yuan Xiao.

"Teacher Yuan," Ferreya asked for advice, "see how long it will take."

"I don't know the strength of your school's equipment," Yuan Xiao said honestly, "If the conditions are sufficient, I certainly hope to build better equipment, after all, the experiment requires high precision."

A leader of the Ministry of Science and Technology said: "There is no problem with this, and the Ministry of Science and Technology will fully support it."

"Then thank you very much." Yuan Xiao remained polite. In fact, he had doubts about the attitude of the Ministry of Science and Technology to support him.

It's just that he hasn't considered this matter deeply yet, so he doesn't need to discard other people's good intentions.

Everyone discussed for a while, and the production of Yuanxiao experimental equipment was not difficult. With the full support of the Ministry of Science and Technology, the result was soon.

It is inconvenient for this piece of Yuan Xiao to stand out, so as not to be suspected of boasting.

Froz concluded: "It takes about three days to manufacture the equipment, that is to say, within five days at the latest, we can get a preliminary conclusion.

However, I personally think that the time of the experiment should be extended. Considering the revolution of the Bruya planet, we need to conduct tests in various orbits to ensure the correctness of the experimental results. "

Yuan Xiao has no objection to this point, in fact, this is the rigorous method.

"Preliminary results will be available in five days," Froz looked at Yuan Xiao, "If the measured wavelength does not change, which means that there may be no ether, the follow-up development..."

Froz actually knew it well.

Yuan Xiao was able to come up with such an experiment, which shows that he knew it well.

There is a high probability that I am wrong, and ether does not exist.

It's just that he couldn't understand, since he knew that the ether didn't exist, why didn't Yuan Xiao's "Laws of Nature" published half a year ago correct this wrong concept.

"There is no problem in the follow-up," Yuan Xiao affirmed, "It just depends on the plan of the National University whether it will be held in the form of an open class."

At this time, Ferreya also knew that the opportunity was rare, he smiled: "As long as Teacher Yuan is willing, our school welcomes it very much."

This is a major milestone in the physics world, and of course Ferreia will not let go of the opportunity to make his school famous.

So it's settled.

In the past few days, Froz took the lead in conducting experimental tests.

On the contrary, Yuan Xiao, who made the announcement, raised his legs.

The leaders are also very satisfied and have explained to their superiors.

Everyone left one after another, and Froz seemed hesitant to speak.

Yuan Xiao knew: "Old Fu, I know what you want to ask.

I discovered the information on Newtonian mechanics through archaeology. Of course, I published it without changing the word for the sake of being faithful to the original work.

I didn't do something on purpose, don't you believe my character? "

Only then did Froz smile: "I thought Teacher Yuan liked to slap himself in the face."

Zhou Zhengyi interjected: "His face is fine, but mine is swollen now."

Zhou Zhengyi can be said to be an indestructible supporter of Newtonian mechanics. Yuan Xiao stabbed him to death by doing this.

Yuan Xiao smiled: "Academic research, continuous improvement is very reasonable.

Everyone, don't worry about these small problems, and I will talk to you slowly later.

As soon as the open class was over, I reported my thesis to the two reviewers as soon as possible, and I brought their names when I published it. "

Zhou Zhengyi's eyes lit up: "Brother, you're the one who said that."

Froz also laughed: "I thought my equation, Mr. Yuan would call it Maxwell's equation."

Archeology is greater than self-discovery, which is the law of the world.

A theory, even if it is independently researched now, if the archaeological discovery has the same theory, it will still be named the original owner of the archaeological world.

Froz had already planned that the equation he created this time could not be regarded as his own discovery.

Unexpectedly, Yuan Xiao pushed it and said it was the Maxwell Frods equation.
