City: I Run A Fake University

Chapter 184: Scholar's Doubts?

"Principal Chen, I want to ask a question." Yang Peidong asked politely.

"Scholar Yang, if you have any questions, just ask them directly?" Chen Feng replied heartily.

Yang Peidong smiled and nodded, and said, "I want to ask, how did you summon us to this time?"

"What's this got to do with it? Is it a wormhole or something?"

Dou Dexian, who was on the side, was also caught, and looked at Chen Feng expectantly. It seemed that he was also aroused.

Chen Feng smiled silently, drew a triangle diagram on the ipad50, and wrote a few formulas beside it for Yang Peidong and Dou Dexian to read.

Chen Feng said: "Assuming the universe in this picture, then any movement is relative, and when there is no frame of reference, then the "absolute speed" of any object in the universe is 0." "1

In this case, the resulting three-sided relationship is:

(t)2+(vt)2=(ct)

t=txv(1-v2/c2).

t=t/V(1-v2/c2).

The two scholars saw this formula, pondered for a while, and then suddenly realized.

"This is the so-called Lorentz transformation! In other words, it has something to do with Einstein's theory of relativity!" Yang Peidong looked at Dou Dexian excitedly.

Dou Dexian also understood, and then Yang Peidong said: "From the formula, t becomes smaller, but from the figure, it can be found that no matter what value v is, it will not affect ct. The result of the influence of v is just ct..."

"That's right, this just shows that the relative speed is not slowed down because of slowing down, but it happens that the relative speed becomes faster because of the existence of t." Yang Peidong came to the conclusion of the experiment

Chen Feng found out a report and handed it to Yang Peidong and Dou Dexian, and it showed.

Experimental background:

"In 1905, Einstein pointed out that the speed of light is constant. But Newton's concept of absolute space-time is wrong. There is no absolutely static reference object. Time measurement: the amount is also different with the frame of reference. He used the constant speed of light and The principle of relativity proposes the Lorentz transformation..."

Einstein's experimental hypothesis:

"Assuming that the speed of light is the fastest, the theory of relativity can be deduced, and if there is a method for measuring the speed of light, the theory of relativity for measuring the speed can be deduced.

It took the two of them about ten minutes to review the relativity experiments they had learned. In this document, they noted many things that had been overlooked.

After they read the document, Chen Feng continued: In this experiment, the time defined by Einstein is related to time itself and the speed of light.

That is to say, when the speed of time exceeds the speed of light, how can time flow backwards. But the problem is always and . The time defined by Einstein is related to the speed of light. If the speed of light exceeds the speed of light, Einstein's time reversal will occur......

Next, Chen Feng elaborated on the relationship between the two from the essence of time to three-dimensional and four-dimensional space.

Just 15 minutes. The original concepts in the minds of the two people were replaced by a large wave.

This simple show made the two of them realize how powerful the young man in front of them is.

At the same time, they are also very fortunate that they can meet such a person with real talents and knowledge who is far beyond them. In a word-convinced!

Yang Peidong suddenly remembered his previous doubts.

Why would you invite me who was more than a hundred years ago to be a teacher in such a powerful place?

Although this question is very embarrassing, it is indeed the truth. Yang Peidong is afraid that he will not be convinced [and he thinks that he is more suitable to be ten students here.

Although a little embarrassed, he opened his mouth and asked frankly:

".||Principal Chen, I would like to ask why you invited me here? After all, I was a scientific researcher a century ago. Judging from the current speed of development, the knowledge system I have mastered is completely outdated."

"Although it's embarrassing to say, I also have the same question as President Chen." Dou Dexian also sincerely confessed to Chen Feng.

Chen Feng felt some inexplicable sense of comfort when he saw them being so frank, he saw Chen Feng take a sip of the tea in front of him and said madly:

"I appreciate your frankness, and I will tell you that although this is a century away from the past, it is not the future system of the world."

"Instead, it is a parallel world of the future world..."

(Wang Nuo's) Chen Feng tried his best to explain slowly.

"Looking at it this way, the development rhythm of this world is not following the rhythm of the original world."

"It's like a pair of twins, although they have similarities, but they are not necessarily identical. The characteristics that the elder brother possesses are lacking in Geography.

Chen Feng cleverly used metaphors to explain vividly to the two of them.

"Principal Chen explained it like this, and I understood." Yang Peidong said.

At the same time, he secretly rejoiced that the field he studied happened to be what the military academy needed. Dou Dexian thought the same way.

After all, for a scholar, it is a lifelong pursuit to have access to people and scientific research at a higher level than himself. .
