Like the three laws of physics, geometric optics is also verified by faking it first - to put it bluntly, you guess the answer first, and then try to find a proof, or just make it up.

For example, when faced with the problem of two small balls landing, Aristotle guessed: the heavier one lands first. The evidence he presented was that the feathers fell slowly, and the iron balls fell fast. After fooling the world for 2o years - Aristotle was the most foolish scientist in history - Galileo guessed that two balls landed at the same time and then fell from the Leaning Tower of Pisa to prove it, but he didn't know why. At the end of the day, Newton drew a conclusion about gravitation with his head smashed by an apple, stating that the gravitational increase is the same, and that the large ball and the small ball should hit the ground at the same time.

In fact, from a statistical point of view, scientists have enough time to guess all the possibilities, it doesn't matter if you lose, the point is to guess boldly, it's like buying a lottery ticket, the bet is the time and effort to write the paper, and writing two more papers is like placing a heavy bet, once you succeed - you do. It doesn't matter if you fail, there are more scientists who guess and lose.

When all the elements were not yet present, Mendeleev dared to make a table of elements, and when he did not know what DNA was, Mendel dared to say that the law of heredity - science is a group of fierce people playing roulette, the timid guess red and black, the bold guess the number, and finally see where the ball falls, the winner of the bet accepts the cheers of the crowd, and the loser actively participates in the next opening.

Cheng Jinzhou's luck is that he knows where the ball will land and just needs to wait for it to turn into position, like a cheating dealer.

This time, he deliberately described geometric optics clearly.

What is the use of describing it so clearly, and it may be useful to have flaws to attract the attention of other star warlocks, but where does Cheng Jinzhou care if the star warlocks really apply geometric optics, if possible, it is a matter of discussing more to bring contribution points.

It should be said that Cheng Dashi's nearly 2o years of ivory tower life did not make him a perfect student, but he could definitely exercise his perfect ability to fabricate papers. After completing the normal outline, Cheng Jinzhou began to do the work of deletion and revision, he only wrote the most basic law of linear propagation and the law of reflection, and wrote the principle of reflection unclearly, as for refraction, it was not involved at all.

Geometric optics without refraction is, of course, unconvincing, different from human intuitive perception in the first place.

But Xiao Cheng has a way, his correct law of reflection to accommodate the examples of his incomplete law of reflection, but the answer is correct......

This is a common method used by scientists. The so-called phased research is also -- mankind's understanding of the atomic earth is such a process, and the Dalton earth atomic model is also a process. to the erroneously raisin model and planetary model. and then to the Bohr Earth atomic model. As a progressive study, it is naturally necessary to do so. Of course. It's also a blessing for scientists. The small atom almost gave birth to a double-digit Nobel Prize winner.

He writes cheerfully in his study. In front of the underground people, there was a lot of discussion. went to find the Xue family's carriage and traveled to the 6 Dayong and quickly turned around. He didn't report to Cheng Jinzhou, standing near the kitchen and blowing: "It's all assigned to the capital." It is also necessary for the carriage to send him a letter, which is the fastest and safest place. Isn't that clear for people to slaughter? ”

"It's not a lot of money for the old man." Immediately someone sourly cooperated. This is naturally their repertoire.

It's a lot of money. 6 Dayong smashed his mouth and said: "Find a girl in Xiaoqi Alley." That's the price. ”

"you. Which aunt > money can make you sleep ......"

"Up to 5oo money."

"6oo is about the same, last time Lao Chen went, he was stunned all night and asked for the same money."

The laughter outside was loud, and Cheng Jinzhou could hear it, but he was just writing and drawing in the study, and he didn't go out to scold. If it was in the Cheng family's old house, it didn't matter if he whipped a group of people, but now it's different.

In the final analysis, the master's prestige at home is inseparable from his status outside, the third room of the Cheng family is in chaos, his second uncle is in the capital, but he didn't send it over with a word, and it is normal for people to have any ideas.

Thinking of the second uncle, Cheng Jinzhou sighed lightly again. The second Cheng Yunxiang and Cheng Yunan are brothers-in-law, and they have the title of the head of the ministry, so they can be said to be the most beautiful second generation of the Cheng family, but after Cheng Yun'an's accident, he was silent and made a clear gesture of avoiding suspicion.

In fact, a 1 official department director can't help much, but Cheng Jinzhou thinks about it himself, and he always feels unhappy.

The people from the Huo family's carriage and horse company arrived soon, and 6 Dayong went out to greet him twice, and then came in and reported without any rules: "Third brother, the people have arrived." ”

"The Huo family?"

"Yes."

Cheng Jinzhou will write a letter long ago

, walked out of the door and handed it to the guy of the Huo family's carriage and horse shop wrapped in a white turban, and said that he would turn the room. It's okay to ask a few star warlocks directly, but after all, it's too time-consuming, and if the other party doesn't finish asking, maybe how many things will leak out, the letter will be the same, and there is enough time to organize the language, and the other party's questions will naturally be limited to the scope.

Locked in the house by himself, Cheng Jinzhou continued to revise and complete his thesis. The intentional control of the content made him feel a happy sense of control, as if he was able to manipulate a certain field.

The results report of the Star Warlock Association is slightly similar to the form of the paper that Cheng Jinzhou is familiar with, but there is no cumbersome content such as an introduction, and under normal circumstances, there is only the first work, and there is no second and third work, and the main text only needs to be written clearly, and there are no special requirements.

Cheng Jinzhou has not completed many papers by himself, but he has copied and read a lot, and he can easily complete more than a dozen pages of content in an hour, and he also made up a real thing - physics, which is always essential......

If the writing is smooth, time will pass very quickly. When it was getting dark, a maid came in and said, "Third brother, the meal is ready." ”

After coming to this actual half a year, Cheng Jinzhou was somewhat accustomed to his aristocratic status, and his brows furrowed and said: "I don't understand the rules, who let you in." ”

As he spoke, he erased the miswritten words and wrote a new one next to them—under normal circumstances, the entire page of the miswritten word should be rewritten, but he made a lot of mistakes, and he liked to be lazy, so he wrote on each piece of paper as if it were a plaster.

The maid felt wronged, so she had to retreat outside the door and knock on the door: "Third brother, it's time to eat." ”

"Bring it to my house, did you receive the reply?" Jinju didn't look back.

"Just got it." The maid whispered.

When Cheng Jinzhou heard this, he said angrily: "Why don't you come to report." ”

The maid was less than 2o years old, and said with tears in her eyes: "You said that you are not allowed to disturb you before dinner." ”

"When will I ......" Cheng Jinzhou replied; I really said it myself, but I still felt extremely uncomfortable. This era is different from later generations, and it is not a big deal for multimillionaires and billionaires in the 21st century to do it themselves, and having a secretary and housekeeper to help is to save effort and put on a show. But in the environment of the Great Xia Dynasty, a competent subordinate is indispensable, and the nobles can never drive the carriage in person, or bargain with the peddlers and pawns, and if they are awkward and do not talk about it, the efficiency will be even lower. When he came to the capital, Cheng's mother originally wanted to borrow the help of the Liu family to spend a period of time first, but she didn't think that the old lady of the Liu family didn't want to admit this marriage at all.

There are priorities, Cheng Jinzhou waved his hand in annoyance: "Go down, bring me the letter too." ”

Dinner is just a simple three dishes and one soup, the whole courtyard, the host family is only a 13-year-old child in Cheng Jinzhou, the people can't say that they can't bully the master, and they will never be serious.

Fortunately, the level of the master is still there, Cheng Jinzhou is eating the dishes while looking at the letter sent by Xiang Xin. Three important laws, Xiang Xin knows one and a half, light travels in a straight line, which the astrosorcerers have long judged, of course, it is also an axiom and cannot be proved - in fact, the proof is meaningless, but to prove that the gravitational field can bend light, and indirectly proves the correctness of the theory of relativity in the 2o era.

The reflection of light is also known to the astrologers, but they do not yet know the normal (a virtual line perpendicular to the incident surface in order to solve the reflection problem). In fact, there is no normal, to put it bluntly, it is to start observing light, but it is not systematically processed mathematically, but it is suitable for the exhibition process of the 17th century. It also shows that their geometric optics are still in their infancy.

After eating, Cheng Jinzhou sorted out the manuscript again, simply deleted the content of the first few pages, thought about it, and simply listed the content of the normal into a separate article. Then he continued to write to Xiang Xin and asked her questions about refraction.

So tossed until midnight, Cheng Jinzhou sealed the written paper and put it in a manual envelope, the two articles were actually not bothered, the real trouble was the transformation of weights and measures and algebraic symbols, Dr. Cheng Da had the heart to define a string of symbols by himself, but unfortunately the status was not enough, and it was always a little strange to use mathematical symbols that he was not used to.

"6 Great Bravery." Regardless of whether it was dark or not, Cheng Jinzhou still called up.

"Third brother." Although he didn't follow the rules very well, the people who should have stayed at the door still stayed.

"Go and call someone from the Xue family to get the letter."

6Dayong looked at the sky that was already completely black, and said reluctantly, "If you go and call now, the cost of the journey will be doubled." ”

"Then let them double it." Cheng Jinzhou said and pointed to the location of the envelope.

6 Dayong responded without doing anything, and roughly cleaned up the table, and then walked out with the envelope.
