Chapter 93 Straight Lines of Light
Cheng Jinzhou, who was sitting upstairs, didn't know that he was being watched again.The small rooms on the second floor are very private, and it is almost impossible to feel the passage of time after closing the door.Instead, there are many ordinary servants serving here. They will bring in food regularly and clean the house. At the same time, it is also to make sure that the astromancer inside is still alive—don’t underestimate the latter point. In history, the astromancer who performed dangerous experiments I don't know how many legendary figures who were found dead at home can make a list of the 50 most wronged dead stars.

As usual, the windows are at a height of three meters. Cheng Jinzhou chose to sit in a position where the sun can shine when he couldn't see the outside.The spots of light are arranged in different shapes on the table, gathering together for a while, and dispersing for a while.Cheng Jinzhou looked down at the book, thinking nonstop, and occasionally drew a few strokes on the paper.The early stage of geometric optics is not complicated. Even if you forget it, you can deduce it if you know the principle, and the experiments are very simple. All he has to consider is how to get more references.

The impact on Cheng Jinzhou of not being able to puncture the star array is far greater than what people think.Others may think that it is normal for a 13-year-old boy not to be able to puncture the star array, but Cheng Jinzhou will inevitably have to worry more—perhaps it is precisely because of the special nature of the star array that it cannot be shown on him.If this was the case, then becoming a pure star warlock became his only choice.In the unpredictable time of the ring, the things that can be handed out are limited after all, how to use this knowledge is no longer just a matter of maximizing benefits.

There are not many theories that Cheng Jinzhou can fully recount, including calculus and analytic geometry, most of them are commonly used classic theories, so that he can be impressed by repeated use and learning, and the side details that are easy to come up are far away. not the focus of his research.

Content such as geometric optics almost gave him a rare feeling.

Of course, Cheng Jinzhou is not really in a hurry. Ever since he met Comrade Dali Temple, things have started to straighten out. Once his father can secure his official position, all the previous problems with the Cheng family will naturally disappear.

It's not impossible to expect a two-star warlock.Even after exchanging most of the contribution points, Cheng Jinzhou still maintained a strong upward momentum.His mood calmed down, and it also allowed him to experience the academic life of astrologists.

Things like academics are like fruits, which look like a lot, but only after digestion do you realize that most of them are water—as for the seeds that can take root and germinate, they are as pitiful as lean meat in cheap fast food.

When astrologists start to study geometric optics, they will naturally try to write every detail clearly. For example, a sentence of application scope can discuss a dozen or more articles, but after the dust settles, the essence The sexual content is often just a sentence of the conclusion.When Cheng Jinzhou reads these journals, he basically reads the final conclusions.As for the process, he didn't need to look at it to know right from wrong.In other words, the current content and process are meaningless to him, so it is quick to flip through the article, and it doesn't take long to read everything at hand.

Most of the content organized by the association on the bookshelf at the door is subdivided, and few can really affect the research process.In the 21st century, it can be said that they are all articles that deceive the number of papers published. After reading a few compilations, the general direction will be clear.

"The rest seems to be diffraction." Cheng Jinzhou grabbed the pen, rubbed it and started thinking.

Diffraction and interference of light refers to the phenomenon that when light encounters a small hole or a narrow gap, it will leave the straight path and go around the shadow of the obstacle - it seems that this is not true when considered by normal people's thinking. It is easy to imagine how light can bend, but such a result has indeed been obtained in the experiment, but the holes and gaps are required to be very small, almost close to or smaller than the wavelength of light.In nature, such phenomena are naturally difficult to observe.

Cheng Jinzhou is not sure whether the famous theories such as the wave theory of light and particle theory are developed naturally from geometric optics, but he knows in his heart that no matter whether he is involved in related issues or not, there must be someone who has already understood the nature of light. And will continue to issue constant questions, but the previous people have not had the opportunity and ability to solve this problem.

If we have to wait until all the foundations of optics are prepared, it will take about the 19th century before people will thoroughly discuss the nature of light.One of the advantages of the astromancers is that maybe the experimental conditions are not available, but the star array can make up for it.Thinking so, Cheng Jinzhou simply wrote down the famous double-slit interference experiment.In his opinion, as long as the technological development he promotes will not suddenly transcend the background of the times, but there is no need to treasure it-it can be bought at a good price.

Cheng Jinzhou sat there, rethinking the experimental process, and then noted what was needed, followed by the familiar experimental process and results - still sitting, in about 10 minutes, he used three sheets of paper , retelling it, but as for things like real experiments, there is no such thing at all.According to some celebrity anecdotes, Mr. Galileo did the same thing back then.

Now that you know the conclusion, why do you still do experiments? The most important enlightenment Cheng Jinzhou got in the school classroom is: if you seriously experiment with the mentality of a pioneer, it is difficult to obtain and teach with the equipment that has been honed over time in school. Answers with the same goal, the result is likely to be a C or D, and if you simplify the process and fabricate a similar data, the result is likely to be an A.Of course, there is no problem with the teaching method. The problem is often just lazy teachers and poor experimental equipment. They often only look at the conclusion and not the process, just like what Cheng Jinzhou is doing now.

After deciding on the direction, he started writing very quickly. Looking at the two papers that were quickly produced, Cheng Jinzhou felt a sense of joy all over his body, as if he was seeing a series of contribution points.

By the time he went downstairs, it was already dark outside.

Just like the laboratory building of later generations, many gentlemen in the Astrology Association read and read, and wrote and wrote day and night.Otherwise, they may not be able to keep up with the times.In contrast, level-level star warlocks who take the practice route seem much more relaxed. In normal days, second-level and third-level star warlocks, etc., at most work for high-level star warlocks, or simply do some work beforehand. Contribute to the association in exchange for contribution points and so on.The mechanism of the association for thousands of years can allow both parties to achieve a certain balance.

Several star warlocks looked at Cheng Jinzhou who was walking down the stairs, and soon became busy themselves.Cheng Jinzhou wrapped the envelope containing the paper and put it into the iron box used to submit results.Speaking of which, as a one-star warlock, he has been able to submit papers directly to the officials of the association and apply for direct review, probably because of his behind-the-scenes mentality, so that he doesn't want to bother others.

An astromancer sitting next to the temporary bookshelf carefully looked at Cheng Jinzhou twice, and when he was about to leave, he asked, "Is this Cheng Jinzhou astromancer?"

"It's me..." Cheng Jinzhou hesitated for a moment, he was still not familiar with this title.

"My name is Zhang Tinghua. I've been reading your results report recently. I wonder if I have time. We have something here that I would like you to take a look at." The three astro-warlocks sitting with him all turned around, and one was about his age. young people, and the other two are about 40 to [-] years old. The relationship between the four seems to be very good.

There are piles of books on their desks, not only the books stamped with the chapter of the association, but also many of them seem to be brought by themselves. This reminds Cheng Jinzhou of his postgraduate days. I don't really care about age, on the contrary, the older the student, the harder he studies. Sometimes, he will be taken to the library to review—of course, he often does cheat sheets in the library before the exam.

Cheng Jinzhou recalled the "vivid years" in the past and said with a nostalgic smile: "Of course."

Zhang Tinghua showed a happy expression.If there was only one nobleman, Cheng Jinzhou would never want an astrologer to ask him, let alone be happy with his answer.In that regard, he has come a long way.It's just that with the improvement of status, the problems encountered will not decrease, and the world is often not always satisfactory.

Zhang Tinghua is both a one-star warlock and a first-level star warlock. All his friends are one-star warlocks, but there is only one first-level star warlock.In fact, it's not that first-level star warlocks are rare, but in the archives of the Star Warlock Association, the density of star warlocks is higher, just like there are more diarrhea patients in public toilets and seafood restaurants.

Cheng Jinzhou was not in a hurry to go back, and simply sat on the other side of the table, introduced each other to the four, and after receiving instructions, picked up their discussion records and read them.

In the records, most of them are about the refraction of light, which is the part Cheng Jinzhou is most familiar with, which made him feel at ease immediately.In this world, if he wants to play with optics, he really has the confidence to give it to me.

Zhang Tinghua waited for Cheng Jinzhou to look at it for most of it before he said in a low voice: "We found that in the process of refraction, the light doesn't seem to be very, very precise, so I came up with an idea that the light might not be a straight line."

Of course, light is not an absolute straight line. The so-called wavelength of light actually fluctuates up and down. Geometric optics is also based on Fermat's principle - the same Fermat, an unavoidable figure in the 17th century - it proposed The principle of the shortest light time allows geometric optics to be developed on this basis.In a few hundred years, people may overturn it for the sake of greater accuracy, but it is difficult to understand that it seems completely unnecessary in the 17th century.

Cheng Jinzhou frowned tightly and said, "Do you think light is not an absolute straight line?"

"In a broad sense yes, but it's not always in a straight line."

Cheng Jinzhou remembered that the older astromancer was named Qin Kun, who was also a leisure nobleman, and the question he asked was also a toothache for leisure.He didn't know how much the other party knew. He shook his shoulders and quickly flipped through the discussion records in his hand, and then said: "I don't know under what circumstances you have such an understanding."

When a normal person looks at a beautiful woman, they will never notice that the light is distorted, but it is possible for the lower body to be distorted.

"When we observed the Grizzly Bear constellation, we felt that the light had changed." Qin Kun and others looked at each other.

Sure enough, it was Tianwen. Cheng Jinzhou patted his head, thought for a moment, and said, "If you don't mind, how about I give you an answer in a few days?"

If it was about other questions, he might be vague, but since it is about optics, he would like to give some guidance. It would be great if he could follow his own research direction.

Zhang Tinghua quickly wrote down the contact information of himself and others on the paper, not only the detailed address, but also the information of the authentication stone.Only then did Cheng Jinzhou remember, took out the certification stone, and bumped into them.

Cheng Jinzhou staggered out of the association's gate, and the four star warlocks hid their heads in the dim light again.

Shi Yan could only wait in the rest area outside. He drank several cups of strong tea and his eyes were as green as tea leaves. Came to see you a few times."

After 9 o'clock in the evening, when Cheng Jinzhou was clear-headed, he glanced at Shi Yan and said, "You took money from him?"

"I..." Shi Yan jumped.

Cheng Jinzhou waved his hand and said, "It's fine if you want to take some of the door bag or something, but you should be careful if you damage the owner's house."

His tone was flat, but what he said made Shi Yan kneel down directly.

"Get up, let's talk about things." Cheng Jinzhou was secretly proud. He had not negotiated a deal with the maritime firm. If Shi Yan didn't take his money, he wouldn't look anxious and excited, worrying about making mistakes—for both parties , he can only be wrong about the maritime business.

Shi Yan swallowed and whispered: "They said they want some candy, no matter how much, please go over and discuss..."

He wanted to say something, but he was too cowardly to say it.I don't know how many things about the other party, and I secretly regret the 5 taels of silver I got.

Cheng Jinzhou nodded noncommittally and said, "What about the price?"

Shi Yan shook his head lightly.

"Then I'll leave it to you to discuss." Cheng Jinzhou glared at him and said, "Ask carefully."

"Yes." Seeing that Cheng Jinzhou didn't lose his temper, Shi Yan became more and more careful because he couldn't figure out his temper.

Cheng Jinzhou thought about it himself. Maritime merchants probably require large quantities of goods. Since the other party said a lot of words, he might have the intention of making friends-he is not self-inflated. Among a group of high-ranking children in Hongwenguan, they are not top-notch, but in the entire Xiajing, or the so-called business world, they are definitely not small.If he went back to Shaonan now, he would have no problem building a small family.

If he hadn't seen a noble involved last time, he might have traded with them several times.Thinking of this, Cheng Jinzhou also wanted to make full use of the ring, and ordered again: "You can rent a few more docks. The place should be big, quiet, and easy to get in and out."

"Yes."

"From now on, it's up to you to discuss matters with the Maritime Merchant Guild." Cheng Jinzhou said with a serious tone: "If there is another problem, I will sell you to the extreme west."

Shi Yan's green tea face immediately changed to oolong tea.
