Future library

Cheng Jinzhou, who was sitting upstairs, didn't know that he was being targeted again. The small rooms on the second floor are very private, and you can hardly feel the passage of time after closing the door. Instead, there are many ordinary servants serving here. They will bring meals in regularly and clean the house. They also make sure that the astromancer inside is still alive - don't underestimate the latter point. In history, astromancers conducted dangerous experiments. I don’t know how many legendary figures were found dead at home. If you just scroll through them, you can compile a list of the top 50 Death Stars who were most unjustly accused.

As usual, the window was at a height of three meters. When he couldn't see the outside, Cheng Jinzhou chose to sit where the sun could shine. The light spots are arranged in different shapes on the table, sometimes gathering together, and sometimes spreading out. Cheng Jinzhou lowered his head to read, thinking nonstop, and occasionally making a few strokes on the paper. The early stages of geometric optics are not complicated. Even if you forget, you can deduce the principles if you know them, and the experiments are very simple. All he has to consider is how to get more citations.

The inability to carve the star array had a greater impact on Cheng Jinzhou than people thought. Others may think that it is normal for a 13-year-old boy not to be able to carve a star array, but Cheng Jinzhou cannot help but have more to worry about - perhaps it is precisely because of the special nature of the star array that it cannot be expressed on him. If this is really the case, then becoming a pure star warlock becomes his only choice. In the unpredictable time of Jiezi, what can be taken out is limited after all. How to use this knowledge is no longer just a matter of maximizing interests.

There are not many theories that Cheng Jinzhou can fully recite, including calculus and analytic geometry, most of which are commonly used classical theories. Only in this way can he be deeply impressed by repeated use and learning, and the details that are easy to come up with are far away. It is not the focus of his research.

Content like geometric optics almost gave him a feeling of being rare.

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.

A two-star warlock is not something that cannot be expected. Even after exchanging most of his contribution points, Cheng Jinzhou still maintained a strong upward momentum. His mood calmed down, and he could have a good feel for the academic life of the Star Warlocks.

Academics are like fruits. They seem to be a lot. After digesting them, you realize that most of them are water. As for the seeds that can take root and germinate, they are as pitiful as the lean meat in cheap fast food.

When astrologers begin to study geometric optics, they will naturally try to write every detail clearly. For example, a sentence of application scope can be discussed in a dozen or more articles, but after the dust settles, the essence The sexual content is often just one sentence in the conclusion. When Cheng Jinzhou reads these papers and journals, he basically reads the final conclusions. As for the process, he knew what was right and wrong without even looking at it. In other words, the current content and process were meaningless to him, so he flipped through the article quickly, and it didn't take him long to read everything at hand.

The content compiled by the association on the bookshelf at the door is mostly segmented, and few can really affect the research process. In the 21st century, it can be said that they are all articles that lie about the number of publications. After reading a few collections, 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 narrow gap, it will leave the straight path and go around the shadow of the obstacle. Using normal thinking, this seems to be inappropriate. It is easy to imagine how light can bend, but such results have indeed been obtained in experiments. The only requirement is that the holes and gaps are very small, almost close to or smaller than the wavelength of light. In nature, such a phenomenon is naturally difficult to observe.

Cheng Jinzhou was not sure whether famous theories such as the wave theory of light and the particle theory were naturally developed from geometric optics, but he knew in his heart that no matter whether he was involved in related issues or not, someone must have already known about the properties of light. And will continue to raise questions, but people in the past have not had the opportunity and ability to solve this problem.

If we had to wait until all the basic preparations for optics were completed, it would be around the 19th century before people would thoroughly discuss the properties of light. One of the benefits of the Star Warlocks is that perhaps the experimental conditions are not met, but the Star Array can make up for this. Cheng Jinzhou thought so and simply wrote down the famous double-slit interference experiment. In his opinion, as long as the technological development he stimulates will not suddenly transcend the background of the times, there is no need to be self-conscious - 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. According to some celebrity anecdotes, Mr. Galileo did the same thing back then.

Now that we know the conclusion, what else are we doing to experiment? The most important revelation that Cheng Jinzhou got in the school class is: if you seriously conduct experiments with a pioneer mentality, it will be difficult to obtain and teach with the equipment that has been tempered by the school. For an answer with the same purpose, the result is likely to be a C or D, but if you simply process and compile similar data, the result is likely to be an A. Of course, there is no problem with teaching methods. The problems are 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 walked downstairs, it was already dark outside.

Just like the laboratory building of later generations, many gentlemen in the Star Warlock Association read, re-read, and wrote again and again day and night. Otherwise, they may no longer be able to keep up with the times. In comparison, the level star warlocks who take the practical route seem to be much more relaxed. In normal days, the second-level and third-level star warlocks, etc., at most work for high-level star warlocks, or simply do some previous work. Contribute things to the association in exchange for contribution points and so on. The association's thousands of years of mechanism 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 association officials and apply for direct review. This is probably because of his behind-the-scenes mentality, which makes him not want to trouble others.

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

"It's me..." Cheng Jinzhou hesitated for a moment, he was still a little unfamiliar with this title.

"My name is Zhang Tinghua. I have been reading your results report recently. I wonder if you have time. We have something here that I would like you to take a look at." The three star warlocks sitting with him all turned around, one of whom was about the same age as him. There are two young people, and two others are about thirty or forty years old. The relationship between the four of them seems to be very good.

There were piles of books on their desks, not only books stamped with the association's seal, but also many that seemed to have been brought by themselves. This reminded Cheng Jinzhou of his graduate school days. At that time, none of his classmates seemed to be the same. Age doesn't really matter. 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 makes cheat sheets in the library before exams.

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

Zhang Tinghua showed a hint of joy. If Cheng Jinzhou had only one noble status, he would never want a star warlock to ask questions, let alone be happy with his answer. In this regard, he has improved greatly. However, as one's status increases, the problems one encounters do not decrease, and things in the world are often not always satisfactory.

Zhang Tinghua is both a one-star warlock and a first-level star warlock. All of 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, it's just that in the Star Warlock Association's database, the density of Star Warlocks is higher, just like there are more people with diarrhea in public toilets and seafood restaurants.

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

Most of the records were about the refraction of light, which was the part that Cheng Jinzhou was most familiar with, which made him feel at ease immediately. In this world, if he wanted to play with optics, he was really confident that he would give it to me.

Zhang Tinghua waited for Cheng Jinzhou to see most of it before he whispered: "We found that during the refraction process, light does not seem to be very precise, so we have an idea that light may not be straight."

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?"

"Broadly yes, but it doesn't always stay a straight line."

Cheng Jinzhou remembered that this older star warlock named Qin Kun was also a leisure noble, and the question he asked was also about leisure's toothache. 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, he will never notice that the light is distorted, but it is possible that the lower body is 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 he were asked other questions, he might be vague, but since it was about optics, he was willing 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 did he have the detailed address, but also the information of the authentication stone. Cheng Jinzhou then remembered, took out the certification stone, and touched it with 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. His eyes were as green as tea leaves. When Cheng Jinzhou came out, he ran over with a look of joy on his face and said, "Third brother, I'm from Maritime Trading Company." I came to see you several times.”

After 9 o'clock in the evening, when Cheng Jinzhou was clear-headed, he glanced at Shi Yan and said, "Did you accept money from others?"

"I..." Shi Yan jumped.

Cheng Jinzhou waved his hand and said, "It's fine if you want to collect door bags or whatever, but if you cause damage to the master's family, be careful."

His tone was calm, but the content of his words made Shi Yan kneel down directly.

"Get up, let's talk about it." Cheng Jinzhou was secretly proud. He had not negotiated a deal with the maritime firm. If Shi Yan hadn't taken anyone's money, he would naturally not look anxious, excited, and worried about things going wrong - for both parties , the only thing he can make mistakes is the maritime trading company.

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. He didn't know much about the other party, so he secretly regretted the five taels of silver he got.

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

Shi Yan shook his head slightly.

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

"Yes." Seeing that Cheng Jinzhou wasn't furious, Shi Yan became more cautious as he couldn't figure out his temper.

Cheng Jinzhou himself thought that the maritime merchants probably required large quantities of goods. Since the other party said so many words, he might have the intention of making friends. He was not self-aggrandizing. The heir apparent of the Cheng family added the title of a one-star warlock. He is not considered to be a top-notch person among the high-ranking disciples of Hongwen Hall, but in the entire Xia Jing, or the so-called business world, he is definitely not small. If he returns to Shaonan now, there will be no problem in starting 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 will be up to you to negotiate matters with the Maritime Merchant Guild." Cheng Jinzhou said in a serious tone: "If there is another problem, I will sell you to the far west."

Shi Yan's green tea face suddenly turned into oolong tea.
