Chapter 95: Discussion (2)

The warlocks were not only the people present piled up countless articles, but also the powerful figures, so even though Cheng Jinzhou was full of confidence, someone asked: "Then please explain what refraction is."

"That's another article I'm going to write. If I tell you..." Cheng Jinzhou deliberately flipped his hands.

The obvious distrust made Tang Wen very angry. If it weren't for the sake of others, it might have been revealed long ago. He suppressed and said, "As a formal meeting, your words and results will be recorded and counted as a report of the achievements of the astral warlock..."

Cheng Jinzhou smiled proudly in front of the white board with his hands behind his back.

Since ancient times, those who can write papers can be assistants; those who can make a paper into two are called lecturers; those who can turn a paper into three are called associate professors; those who can hold a paper in their hands and have endless changes can be professors.

Now, Cheng Jinzhou has transformed simple and clear geometric optics into an incomprehensible awkward academic report. Cheng Jinzhou feels that he is also considered an associate professor. Unfortunately, the pleasure of success cannot be shared with everyone, just like the feeling of indecent things leaking into his pants - they are all cold in private.

"Cheng Jinzhou Star Warlock?" The host interrupted Xiao Cheng's reverie and said, "Do you need experimental equipment?"

The most realistic use of astrology warlocks is naturally an indispensable part of their research. The host's words were even more interrogative. It was obvious that he also tended to be Anfeng's star warlocks. In fact, although the imperial astrology warlocks always dominate the association with the peripheral peninsula as the radiation range, he had more opponents.

Cheng Jinzhou looked at him contemptuously. If he had arrived in this world at the beginning, someone suddenly asked him "how to do an experiment that proves the existence of refraction", he might have difficulty recounting the standard experimental steps for a while, but after sufficient preparation, he would find fault with such middle school-level problems, which would make him feel uncomfortable.

"I have a piece of glass brick, white paper, positioning needle gauge and a wooden board." Xiao Cheng reported it as if he was reciting.

Such practice and accurate explanation immediately made Tang Wen feel a bad feeling. He wanted to find help from An Fengxing Warlock, but he could only see his back.

Xu Guxing's sorcerer hurriedly ordered his kung fu to go all over the floor. Then he saw three sorcerer apprentices carrying three boxes and walking up to see it. They were all glass tiles of different sizes.

"It's really a glass." Cheng Jinzhou murmured to himself. In Shaonan City, he didn't have the chance to see such a thing.

"I bought land from other places." Xu Gu briefly introduced. The Xiajingdi branch is the largest among the many branches of the Daxia Dynasty. It is not necessary to say that all kinds of materials are available. It is not uncommon to store some glass bricks in other cities and even one of the national and local transportation centers.

Cheng Jinzhou raised his eyebrows. He knew that there was glass in Europe in the 13th century. Unexpectedly, although the astrology warlocks failed to make the times faster, they made it easier for the East and the West to communicate.

I randomly chose a piece of glass as big as a brick and shaped it on the table. I thought in a slight way: If I accidentally fell on the ground and broke it, I would know if several astrology warlocks would hurt.

While doing a standard refractive experiment, he introduced: "When we see the position of fish in the water, if we use harpoons or something to stretch, it will often deviate. The reason is refraction."

Although the principle of eyes has been discussed by early humans, it has not achieved much success. The astrology warlocks present did not want to change the topic, but just listened quietly and said nothing.

Cheng Jinzhou was inexplicably nervous for a moment, then he became serious again, and used a positioning needle to first determine the position of the light beam that did not pass through the glass, then add the glass bricks, and then determine the position again, and the angle between the two was clearly seen.

Tang Wen breathed a sigh of relief. In his opinion, if it were just these, he would not be completely embarrassing today. The experiments in front of him were too simple. If he wanted to explain only the existence of refraction, there was nothing rare in essence. Although everyone did not want to study the meaning of optics, he understood some basic content.

Although some people on the Jiang Huang Star Warlock did not trust his so-called geometric optics, they were difficult to refute, so the astral warlocks on the Anfeng Star Warlocklock started looking at each other.

Finally, when Cheng Jinzhou was about to complete, one person stood up and said, "If you do this, you can prove the existence of what you call refraction, but this is what we all know, and it has nothing to do with geometry."

"So what do you need?"

"Quantity Relationship." This astrologist has a clear mind. Quantity Relationship is the most used thing, but it is also the most difficult part, and it is easier to be picked out and omitted.

The completion of a formula often requires generations of hard work, and those who are more impatient often fail. Cheng Jinzhou has no similar problems, but he did not say it smoothly, and only smiled twice:

This Tang Wenxing Warlock, may I ask you to attack the enemies in the water in the past.”

He almost used the Six-Meridian Divine Sword to illustrate the other party's star formation.

Unexpectedly, Tang Wen was caught again and said with a look of bad temper: "There is usually a deflection angle, and what you say is what we know."

From an empirical point of view, he can understand the existence of a deflection angle, but positioning is far from enough.

Cheng Jinzhou smiled mysteriously and wrote two simple trigonometric functions on the blackboard, private n and cos, and then replaced them with symbols familiar to the astrology warlocks. For example, he said lightly: "The sine value of the incident angle is greater than the sine value of the upper refractive angle, which is equal to the refractive index of medium two than the refractive index of medium one. It is a very clear formula. Mr. Tang, please use this formula to experiment with the refractive index of water."

Tang Wen frowned and said, "I know what the refractive index you are talking about?"

"The refractive index of water is 1, which is a free message for you."

Of course, Tang Wen did not submit. He simply activated the star array and built an ice pool the size of a bathtub on the ground. After filling it with water, he threw the jade pendant he carried with him in the water and said, "If you can accurately calculate where the eye on my jade pendant is, I agree with your formula. If you can't, please pay me a jade pendant."

It is also known that the jade pendant that Tang Wensui brought would definitely not be cheap, but Cheng Jinzhou agreed without hesitation and recruited the astrology apprentice who had called the waiting side and said, "Go and find two astrology monks who can measure angles."

"Just do it."

The called apprentice is 20 years old, and he still has to hold the etiquette of his juniors when facing Cheng Jinzhou.

"Be more precise." Cheng Jinzhou instructed and explained the algorithm of the refractive theorem on the whiteboard. His voice just made the star warriors in the audience understand the content. At this time, everyone had predicted Tang Wen's fate.

Mathematics is a very practical subject. It is the most unwise way to make up data.

In addition to using a little knowledge of trigonometric functions, the refractive theorem itself only needs to be calculated at elementary school level. The apprentice's certification will be able to go forward in two or three minutes, and face the positioning of the jade pendant in the ice basin.

The degree is 13 minutes, the result is 1254 meters, and the above 60 meters." According to Cheng Jinzhou's description, the coordinates reported by the apprentice of the Astrology Warlock.

An Feng was slightly moved. He knew his old friend's research scope and felt a strange feeling about Cheng Jinzhou's proficient use.

Cheng Jinzhou looked at Tang Wen confidently and said, "Please."

Looking at the jade pendant that was still white in the ice basin, Tang Wen gritted his teeth and, according to the coordinates mentioned by Cheng Jinzhou, a ray of light instantly appeared on his index finger with his right hand.

Several curious astrology warlocks have already come to watch.

The light is yellow, and it is clear at first glance. Some of the light passes directly through the bottom of the basin, but some of them easily pass through the line on the upper part of the jade pendant...

More than one person exclaimed.

Even An Feng Star Warlock and Jiang Huang Star Warlock could not help but have a glimmer of light in their eyes. For the star warlocks, accurate positioning is particularly rare, and their uses can be said to be infinitely wide. Tang Wen also lost the idea of ​​winning, looked at his fingers blankly and thought: If he hides underwater in the future, wouldn’t he be able to accurately attack the astral warlocks and airships passing by in the sky?

The sorcerer Jiang Xing gently raised his body, as if the torso, who had not moved his position all day, needed to move. He himself had a lot of benefits in the Daxia Dynasty, so he could instantly think of the exquisiteness of Cheng Jinzhou's design.

Although astrology warlocks have a lot of research, they mainly use it themselves. Basic research usually requires associations to promote it - the results produced by spending countless funds are relatively easy to get, and the senses are naturally lower.

As if he saw his interest, the second-level astral sorcerer Deng Zhuo asked: "Mr. Cheng, does the refractive index of the medium change? How to prove it? And how do you find it?"

"In some cases, it changes. As for the method of proof, I haven't thought that I have another formula for calculating the refractive index of the medium." Cheng Jinzhou is very smart now. This is the amount of several papers. It is definitely a good time to accumulate contribution points. He is not as good as a high-level astral warlock, who can eat and wear food and clothing.

Geometric optics is the most basic part of later physics. Even if many people give priority to military purposes, it will not have much impact on the times, and it will not have much impact on Cheng Jinzhou's superior knowledge. It is his favorite content.

The scene was a little chaotic. After a moment, An Fengxingshi said slowly: "The Star Warrior Cheng Jinzhou has raised a series of difficult questions for us, and I'm afraid we will have to think about it for a while."

The astrology warlock on his side immediately became as weak as if he had failed.
