Chapter 162 Refractive Optics

The Liu family is also a common surname in the capital. Although it is not as deep-rooted as Qi Doulu's, but during the tenure of Emperor Lizong, it has become more and more famous as a royalist.

Conservatives have always been the stronghold of vested interest groups, and even the Astromancer group will circle outside the conservative camp from time to time.The cleverness of the Liu family is that, while being in the conservative camp, they closely follow in the footsteps of His Majesty the Emperor.

For this reason, they did not hesitate to offend the nobles, the great families, and even the astrologists.

Ten years before Lizong, the Liu family faced danger several times, but they all escaped in the midst of twists and turns.The key person among them is the old man of the Liu family.

Today, although Mr. Liu has entered a state of semi-retirement, he still seems to be a representative figure of the royalists with many disciples and former officials. Every time before and after festivals, the emperor never forgets to send a gift, which is just written in his own hand. The Liu family has collected dozens of couplet poems and books, which is evident from their honor and favor.

In addition, another reason for the Liu family is Liu Kuangxing Warlock.Although the fifth server has already been released, the Liu family finally found a way to get in touch with the Liu family. The Liu family needs to borrow the prestige of the fourth-level star warlock. , although Liu Kuang never married, his nephews and nephews still hope to be taken care of by some important people.

In the case of his own family being extremely weak, the relationship between Liu Kuang and the Liu family is not like relatives but better than relatives.

Holding the invitation from the old man of the Liu family, Cheng Jinzhou felt as if he was holding a red-hot brick.

"Has the person who came here gone back?" Cheng Jinzhou unfolded the invitation card, which only said "Please tell the mansion."

Just six characters, with flying dragons and phoenixes, steel and iron bones, and the writing is very heavy, giving a rather resolute look.It's just that there is not a single extra character in the middle of the entire invitation, which is extremely concise.

Cheng Jinzhou's teeth itched as he chewed, and he felt discriminated against.But he didn't know that it would be easy to be a county magistrate if an invitation like the Liu family's was sent to a county outside.

How can the old man of the Liu family write invitations to other people casually.

"The person who came here has already gone back." Shi Mo was secretly startled as he said that, such behavior that was not in line with noble etiquette would not give Cheng Jinzhou the face of his grandson-in-law.

After a day, Cheng Jinzhou, who has been promoted to the first-level star warlock, looked at the invitation card calmly, and was rubbed by the maid calmly, thinking: Since it is completely different from the emperor's old man, it is useless to replace the chamber pot with a toilet.

Thinking of this, he resolutely said: "I won't see you anymore. Bring a pen and paper."

Shi Mo was stunned for a moment, how could he dare to say a word, went to the room to grind the ink very quickly, using only the leftovers from rinsing his mouth.

Cheng Jinzhou hung his arms slightly, and wrote a line of words in extremely ugly handwriting: I'm a little busy, I'll talk about it another day.

After finishing writing, he flicked the wolf hair and said, "Go, give it to the Liu family."

Looking down at the note written by Cheng Jinzhou, Shi Mo almost cried.Not to mention the shape of the writing style, but just such a sentence, who knows what Liu's attitude will be.

Shi Mo swallowed his saliva, and said in a low voice: "Third brother, this is a letter written by the old man of the Liu family. Your reply letter will definitely be read by the old man."

Shi Mo didn't dare to remind anyone that the errand of delivering the letter fell on anyone, but when it fell on him, he couldn't help it anymore.The second and third generation sons like Cheng Jinzhou may not care about the power of the Liu family, but they know it clearly as slaves.In fact, the servants of each family have always been the most aware of the changes in the ranks of Beijing and China-whoever gives way to whomever drives on the road; You can't be chaotic, you can't be ignorant.

Cheng Jinzhou said with certainty: "Go and send it to the Liu family."

There are priorities, and he can clearly distinguish them.Not only that, but he was even more worried that the old man of the Liu family didn't have the same idea as him - to put someone under house arrest.For the Royalist faction, it would not be too surprising to confine an Astromancer for a few years with His Majesty's acquiescence.Even though they may be under a lot of pressure because of it.

Stress is stress after all.

Cheng Jinzhou was dressed and ready to go outside for a ride.

The horse didn't move, but Cheng's father appeared from nowhere, stopped him personally, waved his reply slip in his hand, threw it on the ground, and said angrily, "How dare you return such a letter to the Liu family."

"That's how they sent it." Cheng Jinzhou looked for Shi Mo with his eyes, who was hiding behind several attendants and dared not come out.

It turned out that this guy didn't dare to deliver the letter directly, so he went to the household department first to find Cheng Yun'an who had gone to work early.

Cheng's father ignored Cheng Jinzhou's actions, threw the letter to him and said, "I will send you to the Liu family personally, the old lady of the Liu family, he is also your elder. You must be filial."

If you talk about etiquette with him, then it will be unclear.Cheng Jinzhou pulled him back, sighed and said, "Father, are you really not afraid that I will be killed?"

Cheng Yun'an was taken aback for a moment, then turned angrily and said: "He is your elder, how could he harm you."

"If I were a foolish scholar, of course he wouldn't harm me. I'm an astrologer now." Cheng Jinzhou even revealed the useless star array on his left arm and said, "In case the Liu family leans toward the emperor, we will A group of knives and axes rushed out. Could it be that the Roujiang family set up a lobby for us to complain? The old man of the Liu family has never welcomed me. You see, we have been in the capital for so long. Have your children and relatives invited us into the mansion once? They can play a role, you are going to be the head of the household department, why are you upside down, how dare Hou Wenwu touch me, an astromancer? He is impatient when he is attacked at both ends."

He was alarmist, but Cheng Yun'an hesitated.That day when Liu Bin got married with him, apart from liking Cheng Jinzhou and finding a way out for his daughter, he was more or less excited for a while—the Liu family is the Liu family, and Liu Bin is Liu Bin.When Liu Bin was alive, the Liu family naturally doted on his daughter, but if he was convicted of the field reform, his daughter's fate would not be much better than life without a family. "

Cheng Jinzhou is also familiar with his father's temper, if he said "I will be under house arrest", Cheng Yun'an might say "Then you go and try".

But when it comes to life and death, indecisive literati will become suspicious.

They don't understand mathematics, they don't know that the small probability time is ignored, what they think is, if it is true...

Thinking about failure before thinking about victory is really the best excuse, the panacea for inactionism.

After appeasing his father, Cheng Jinzhou bent down to pick up the note, flicked his fingers, and beckoned: "Shi Mo, come here."

"Third Brother." Shi Mo cried with a sad face, not daring to say anything more.

"The letter is secure."

"Hold it firmly." Shi Mo knotted the letter from Cheng Jinzhou's hand, and rubbed it hard on his clothes twice.

"Now you are going to Liu's house to deliver a letter, and you are not allowed to say any nonsense. When you come back, you will get 20 small boards yourself, remember?" Cheng Jinzhou's voice was stern, with an undoubted sense of command.

Shi Mo didn't dare to say a word, kowtowed on his knees and said, "Don't worry, third brother, I will definitely deliver the letter."

Cheng Yun'an looked at his son as if he didn't know him, and was a little surprised by his methods. The 20 small board was hit on the back. If it is really hit, it is certain that he will not be able to get out of bed for half a month-he doesn't really care about the punishment of a servant, but Cheng Jinzhou's behavior is inevitable. authority conflicts.

Before he could figure it out, Cheng Jinzhou had left long ago.

As a father, Cheng Yun'an also has a long way to go.

……

In the long-lost outer peninsula, people are healthy, happy, and politically stable.

There are no officials who do bad things, no officials who are corrupt, no officials who collect taxes, and no officials who spend money. The peripheral peninsula with residents' autonomy is almost the template of a small European country.If Rousseau saw it, he would probably drool enviously.

This is a small island that cannot be replicated.

Cheng Jinzhou re-lived in Liu Kuang's Star Warlock Tower.

Although Liu Kuang has a close relationship with the Liu family, he is fully confident that even if Mr. Liu Kuang, a fourth-level star warlock, does not support him, he will not cause harm behind his back.

There are no fools among the Star Warlocks - except for Lu Xu - and every action of the Star Warlocks representing the association must be in the interests of all Star Warlocks.The political help that the Liu family can bring is far from enough to make Star Warlock Liu Kuangxing betray the Star Warlock Group.

In some ways, the high cost and low return of Astrowarrior's betrayal of the group makes it almost impossible-like robbing the Chinese government's bank in the mid-20th century, probably the result of insanity. Moments where you just show your true self.

Taking advantage of the arrival of the people who came to congratulate and say hello, Cheng Jinzhou rubbed open the ring and said, "Mr. Ke, seeing that half of the money has been spent, can you help me find a specific book?"

Among the books he has already obtained, Brunchwick's "A Concise Handbook of Distillation" and Appianus' "Astronomy" are books that are very suitable for the times, especially the latter, which records in detail the determination of longitude by solar eclipses. , The tail of the comet with the sun behind it, etc., although subject to many restrictions, it is the type that can be used.

From the previous selections, except for "Elementary Mental Arithmetic Tutorial", the quality of cheated books is obviously higher.

Customer service 010 said without the slightest consideration: "Your requirements are increasing, and it is impossible for me to satisfy your requirements for specific books. This is completely contrary to the rules of the system."

Cheng Jinzhou coughed, covered it up and said, "Mr. Ke, I'm in a very difficult situation now, I don't know if you know it."

"Do not want to know."

Cheng Jinzhou laughed twice and said, "You don't have to know even if you don't want to. In order to raise 1600 million stars, I ran all over the warehouses around Daxia, but I was hunted down and came here."

"Oh?"

"If you can help me find a book about making a microscope, then I can escape disaster by asking for help. If not, the next time you see it, it is very likely that the person who helped me collect the corpse." Cheng Jinzhou Pretend to be pitiful, but he does need the help of Cao Fengxing Warlock.

Although the second uncle Cheng Yunxiang sent 15 servants, Cheng Jinzhou believed in the fighting power of the star warlock more.

And last time, Hou Wenwu brought an unlucky star warlock.It is not impossible for people who don't know the truth to get involved.

Relatively speaking, he also believed more in the dull Warlock Cao Fengxing, and other ordinary gentlemen, who knew what would change their minds when faced with his danger.

"You want me to get a book and bribe you to other people to get better benefits?" Customer service 010 also put away his airs and countered with sharp words.

Language is at its weakest when it is sharp.

What Cheng Jinzhou was afraid of was that customer service 010 would throw away his hands and leave. What would it matter if they started talking about it.Now it seems that there is indeed something wrong with customer service 010, which caused him to change dramatically.

Thinking of this, Xiao Cheng smiled softly: "You can also understand that I want to serve the Star Alliance better, so I need a little help. Of course, this book must be attractive enough."

He needs the help of Star Warlock Cao Feng, not the help he can get by posting employment information in the Star Warlock Association, and he also has extremely high requirements for the quality of the book.

Customer service 010 wanted to refuse, Cheng Jinzhou quickly said: "If the content of the book is satisfactory, I can directly buy 200 books."

"300 copies." This number is almost close to meeting the requirements of the Covenant Level 4.

Cheng Jinzhou wanted to hold customer service 010's neck for a while longer, and said with a smile, "250 copies, let's not listen to the music."

"Okay, two hundred and five." Customer service 010 agreed, and immediately said: "12 words, are you sure?"

"Sure." Cheng Jinzhou was full of energy.

""Refractive Optics", German, is it translated?"

Cheng Jinzhou immediately said: "Translation."

As a bad student of physics, Cheng Jinzhou knew he had picked up a treasure just by looking at the author's name of "Refractive Optics".

Kepler.This physicist, born at the end of the 16th century and brilliant at the beginning of the 17th century, was indeed the most suitable choice for the star warlocks of the 17th century.His three laws of Kepler made him a top physicist in the 17th century.

His life experience is also very lucky and enviable.He studied at the oldest university in Germany - which is still very old relative to the era of his origin - and obtained a bachelor's degree, then a master's degree, and then stayed on to teach, which was only the first step to make the post-90s college students envious .Next, Mr. Kepler wrote an astronomy book on the basis of Copernicus. Just like most Chinese students and young professors, the content of the book is completely wrong. Mathematical talent.

So, weak in mathematics, but the great astronomer Tycho recruited him as his assistant in Prague - a new chapter in a standard academic career.

Then, in the next best thing, poor Tycho died the next year.Kepler, who had only been at the observatory for a few months, was appointed by the Roman emperor to succeed Tycho as royal mathematician, and God knows how he did it.The most wonderful thing is that the great astronomer Tycho was a very, very careful observer. Judging from his actions, if he was in the United States around the 21st century, he would probably be diagnosed with paranoid mental illness-in Without a telescope, he has recorded the movement of planets in detail for many years, rain or shine, which is extremely valuable. It is no exaggeration to say that there is no one before or after decades of persistence and accurate astronomical work. Mr. Kepler On this basis, the law of planetary movement is explained by mathematics.There are some difficulties. The key point is to break the concept that people in the world thought at that time that the orbits of planets are circular or compound circles, and use ellipses to calculate planetary orbits. However, if you consider that there were so many talented mathematicians at that time, Others' guesses are not supported by Tycho's records, and Kepler's great achievements are almost as if they were picked for nothing.After this astronomical research that could definitely win the Nobel Prize, Kepler’s main research in his later life was optics: he explained the principle of refraction of light, laid the foundation for the refraction telescope, and built a The Kepler telescope, which is more advanced than the Galileo telescope...

Although the Galileo telescope is no different from the telescope assembled by monkeys, in the 17th century, the Kepler telescope, which was improved by one level, still aroused Cheng Jinzhou's interest.

In fact, Cheng Jinzhou really didn't know where concave and convex lenses were used.

He studied theoretical physics, not engineering technology.

Although he was very satisfied, Cheng Jinzhou said deliberately: "The main things in this book are telescopes, which are different from microscopes."

Customer service 010 made a weird voice, and said with a thud: "The telescope first forms a real image that is inverted and zoomed in, and the second time it becomes a virtual image that is erected and enlarged; Virtual image. Both are one upright and one down, one real and one virtual, you should be able to adjust it yourself."

Cheng Jinzhou listened blankly. He never thought that customer service 010 could answer his questions directly.

It seems that the education of the Star Alliance really started from a young age.

"Take it to the person who bribed you." Customer service 010 said and disappeared.

Cheng Jinzhou smirked twice, and went to find Warlock Cao Fengxing without mentioning it.

The era of Kepler was the era when optical craftsmen stood at the forefront of the world. Improving the distance between the objective lens and the eyepiece and reasonable structure of the microscope optical path were the focus of research in those years.Coarse and fine adjustment mechanisms, lighting systems, and workbenches for carrying specimens are things that astrologists have never considered.

Naturally, there are ways to lure Cao Feng to work for him.

……

At the same time, Shi Mo anxiously handed out the note, waited for a while, and seeing that there was no worse result, he hurried back to the house to get his small board, and bought Jinchuang medicine and other preparations along the way.

In Liu's house, the delivery note was given to the staff to read as usual.This gentleman, who has been with the old man for decades, couldn't laugh or cry when he saw the seven characters "I'm a little busy, I'll talk about it another day".

Until the old man went out to bask in the sun, he was still sitting at the door, pondering over and over again.

Old Liu couldn't help but said in unison: "Lao Nan, what incompetent person is bothering you again."

"Dong Weng, I am your grandson-in-law." The two have had a relationship for many years, and Nan Huo, who is an aide, speaks very casually.

"Cheng Jinzhou? Have you booked a date? If Qingshuang hadn't been begging me, I wouldn't have needed to come forward. Look at the piles of things he messed up, and even if he has a little bit of ability, he will go on a rampage. Could it be that Daxia really can't control him? "Mr. Liu said with a cane.

"It seems that I can't control it anymore." Nan Huo shook his head and handed the reply to him, and said with a smile: "Look at it."

Mr. Liu has poor eyesight, so he read word by word: "I'm a little busy, I'll talk about it another day!"

For a while, he was really speechless.

……

In addition to the word count: I have been working hard for 9 days, and the people are really squeezed out. Everyone should also squeeze out the monthly pass or something.Under normal circumstances, please bookmark and subscribe.
