While Cheng Jinzhou was looking at the drawings, Warlock Liu Kuangxing began to talk about his understanding of the similarities and differences between geometric optics and coordinate geometry.

In fact, if we ignore the properties of light itself and regard it as a purely mathematical problem, the two can basically be discussed together.

However, for Cheng Jinzhou, after coordinate geometry comes analytic geometry, and before coordinate geometry is discussed clearly, it is not interesting at all to study analytic geometry, especially when Mr. Liu Kuang is wandering between them.

He didn't want to contribute to Liu Kuang's research work. The emergence of analytic geometry in the history of mathematics was much later than the early calculus, almost a hundred or two hundred years ago. Under the current situation, he would rather put the previous ones first. Sell ​​all kinds of knowledge, and then talk about these more complex and transformative things.

Presumably by then, he will be more capable of using these changes.

Because of this consideration, Cheng Jinzhou didn't listen very seriously to what Liu Kuang said. He was thinking about who was the mastermind of his assassination, and then he thought about the so-called real rice...

For most star warlocks in this world, there is absolutely no chance to listen to Liu Kuang's opinions on a certain issue, let alone a lengthy discussion. It's a pity that Cheng Jinzhou doesn't cherish it at all. As his understanding of astrology in this world increases, his advantage in mathematics is actually gradually revealed.

Especially the arrow he had dodged earlier today made him think endlessly.

Liu Kuang's mouth went dry when he said it. Seeing that Cheng Jinzhou had no reaction, he laughed and said, "You don't think what I said is interesting?"

"Oh, it's just that my research direction is different from yours, and, you know, uh... I'm a little scared..."

Liu Kuang smiled and didn't really ask Cheng Jinzhou to come up with the topic before he said anything. He laughed twice strangely and said, "You really offended a lot of people. This time, it should be the dock gang."

"Where's the envoy?" Cheng Jinzhou didn't care who acted. In his opinion, it was a matter that could be easily investigated.

"It's hard to be sure now." Liu Kuang's smile was actually very friendly, but because Cheng Jinzhou had seen his other face, he always felt it was too fake.

Cheng Jinzhou said "hmm" and didn't quite believe what had just happened. Now he had a conclusion, so he just said: "I have been mainly thinking about geometric optics recently, and then I discovered some interesting things."

"oh?"

"Actually, I also had help from friends. There were a few young people, Zhang Tinghua and Qin Kun, who discovered that light would deflect at certain times, so I also considered this problem and did experiments, and found that it was indeed possible." Cheng Jinzhou was actually just using someone else's name. Zhang Tinghua and Qin Kun were the young people who asked him about the light distortion problem in astronomy that day, and they had nothing to do with double-slit interference. He took it out just in case he needed to explain the source of inspiration.

Of course Liu Kuang would not delve into the reason, and asked with interest: "Is it the paper on double-slit interference?"

"Yes, you have seen it?"

"I have collected all your results reports here." Liu Kuang said and raised his hand, grabbing the book on the first floor of the wall. After opening it, it turned out to be "Record of the New Properties of Light".

Cheng Jinzhou couldn't help but complain: "I don't know why, but everyone doesn't like this article."

Warlock Liu Kuangxing gave him a strange look and said, "How do you know that everyone doesn't like it? This book association seems to have copied many copies, at least thirty or forty."

Thirty or forty books, indicating that in most cases, there are thirty or forty star warlocks requesting to read them at the same time. This is a very high ratio when the number of people is sparse.

Cheng Jinzhou couldn't help but spread his hands and said: "The contribution points have not increased."

Liu Kuang laughed loudly and said: "I see, it's normal, because you raised a big question. I didn't repeat the experiment, but thinking about it, it would be fine if it proves that you are wrong. If it is correct, So the problems derived from this may not be solved in the short term.

Cheng Jinzhou blinked, he had really forgotten about this.

For papers and the like, the one with the highest number of citations is not necessarily the most advanced, just like the best-selling product on the market is not necessarily the most technologically advanced product. Apart from idle and boring science fiction novels, popular science novels and small newspapers that no one reads, who would quote "The Theory of Relativity" over and over again? As for the era when this thing was just released, we should talk about it.

"How about it? What are your thoughts based on this? If light can really bend, it will have a fatal blow to your geometric optics. Do you feel that your contribution has increased very slowly in recent times?"

Cheng Jinzhou immediately blushed and felt extremely ashamed.

He really didn't think about how denying himself would affect his previous articles. Especially actual experiments.

To a certain extent, the reference is to directly obtain the answer, but Young's double-slit interference is an experimental form to illustrate that light will bend at certain times.

Although this bending will soon be reset, for geometric optics, at least proving its axioms is problematic.

Without resolving this paradox, it is understandable that the number of citations of previous articles has dropped significantly.

What makes Cheng Jinzhou embarrassed is that his name appeared on many papers in his previous life, but he didn't pay attention to contradictions, and he was eager to increase his contribution.

Understanding the crux of the matter, Cheng Jinzhou showed a relaxed attitude and said: "I may have a new results report recently, but it has not been completed yet."

"Oh, I still have a lot of vacancies in my star tower. Are you interested?" Liu Kuang said so much, probably just to wait for this sentence.

As the owner of the Star Tower, Liu Kuang does not necessarily know the research projects of each Star Warlock, but he is responsible for maintaining the Star Tower, and the Star Warlocks in the Star Tower will naturally reward him accordingly.

Influence may be one of them.

Joining Liu Kuang's Star Warlock Tower means completely leaning towards Liu Kuang's faction.

Cheng Jinzhou refused without thinking, "I like to study pure mathematics."

Liu Kuang didn't think much of Chu's little vote and said: "There is nothing we can do about it."

At this time, he regretted that it was too late for not directly accepting Cheng Jinzhou as his disciple. If he didn't become a fourth-level star warlock, he might also want to study pure mathematics. Many battles between Star Warlocks often start during the bottleneck period. At this time, Star Warlocks often need more supplies, more manpower, etc., and social resources are always limited. , neither the outer peninsula nor the Royal Star Warlock positions can supply too many Star Warlocks.

Therefore, when Liu Kuang, An Feng, and Jiang Huangxing Warlocks occupied all the resources of the upper echelons of the Great Xia Dynasty, the other fourth-level Star Warlocks either went to other countries or wandered around. Instead, those two-star and three-star star warlocks built star warlock towers near the peripheral peninsula and the capital. Because they do not need to directly participate in the competition for resources.

At this point, Cheng Jinzhou felt a little embarrassed, feeling like he was being favored by others without reciprocating it, so he thought about it, drew a Z-axis on the coordinate axis, and asked: "Have you ever considered spatial graphics? "

"Not a very perfect idea." Astromancers must take space geometry into consideration.

"I have some research in this area, if you need it." Cheng Jinzhou said casually. In his opinion, this is just another two or three years of progress. Without the ring, he would be at least 300 years ahead of the world. With a ring, you don’t have to worry.

However, Liu Kuang felt a condescending feeling of kindness from Cheng Jinzhou's tone. This feeling made him extremely unhappy, as if a wild wolf had bitten off one of the goat's legs and then ran to grab a deer leg to compensate him.

Cheng Jinzhou smiled obliviously and said: "As for the coordinates, that's all I can help with. If you don't mind, can you let me take a look? I mean in the star tower."

"Of course." Liu Kuang glanced at him meaningfully and threw a palm-sized badge to Cheng Jinzhou. In addition to the traditional five-pointed star and the background color, there was also a bright yellow tooth-shaped outer ring.

"What does this mean?" The badge is an important identity certificate for Star Warlocks and cannot be worn casually. Of course, Cheng Jinzhou must ask clearly what it means. He was now pointing to the outermost circle.

"The representative is a guest I invited, the traditional emblem of the outer peninsula." Liu Kuang said, turned around and looked at the Z axis painted by Cheng Jinzhou.

There are countless differences between space geometry and plane geometry. For the level of the 17th century, they still have a long way to go. However, Liu Kuang specializes in geometry, and the attraction of this aspect to him is obvious.

Cheng Jinzhou curled his lips. There seemed to be something strange about making the badge by himself.

When he walked out of the door, Ma Ling, who had been reading in the room, came up to him. Seeing the badge he had just brought, he asked politely: "Hello."

"Oh, does anyone here study grain?"

"Mr. Cao Feng studies practice diligently." When Ma Ling talked about practice, he was slightly disdainful.

Just like poets look down on writers and writers look down on reporters, the superstructure always looks at the people doing things with a condescending eye. Among the group of star warlocks, breaking away from mysterious mathematical problems is almost considered as not doing their job properly.

"Which floor is he on?"

"Second floor."

Cheng Jinzhou walked down first to avoid Ma Ling blocking him.

At the same time, he asked: "I want to contact someone in the capital to explain my situation."

"I will send someone to inform you."

Having just experienced an assassination, Cheng Jinzhou felt that the outer peninsula was safer. Those who could afford a star warlock to be an assassin were probably not available in the whole of Great Xia. Considering this aspect, he said: "If possible, I would like to send two pieces of information."

"Please tell me." Ma Ling was polite and distant.

"Just ask them to give me a name and send it to my house." Cheng Jinzhou tried to keep it simple so as not to make it difficult to understand their complicated astrology system.
