Chapter 1162 Postscript 18: Academia is also a filthy place
There are many types of dampers. Traditional analytical balances have dampers, some skyscrapers have dampers, and cars also have dampers.
But the basic principle is actually the same: the law of conservation of energy.
Moreover, Xie Yan has seen a laboratory balance.
He had a high school classmate who was also an alumnus of the university when he was an undergraduate. The two were inseparable, one was studying civil engineering and the other was studying chemistry.
The four major sinkholes of biochemical environmental materials occupy half of the country.
One day, the two of them made an appointment to meet fellow students who were studying in the same city. They heard that there were several women among them, and they might have a chance to escape the fate of being single.
Xie Yan waited and waited until he called and found out that the chemistry guy was in the laboratory.
He asked along the way and went in without hesitation.
The chemistry guy was extremely surprised: "How did you get in?"
Xie Yan said: "I walked in."
The chemistry guy asked: "No one stopped you?"
Xie Yan looked innocent: "No."
The chemistry guy looked around and found that the teacher had long disappeared.
Xie Yan pointed to the weathered semi-automatic electro-optical balance: "This thing is very expensive, and it's even covered with a glass cover."
"It's junk. It's for undergraduates to practice their skills. The agate knife has been worn out. The graduate students have eliminated it and thrown it to us undergraduates for recycling." The old chemistry guy complained, saying that the school doesn't treat undergraduates as human beings. This
Tai Lao Gu antique is older than the student.
Xie Yan stood aside and watched.
The chemistry guy was operating the scale while explaining the principles to Xie Yan.
After about a while, the laboratory suddenly became quiet. When the two of them looked back, they saw the teacher standing behind them, and the other students were suppressing laughter.
The structure of this thing is very complicated, but once you understand it, it can be said to be very simple.
It is nothing more than an ordinary balance with some devices added to improve accuracy.
The air damper is also easy to make. There is a large tube at the bottom, a small tube at the top, and the middle is full of air.
Those large and small cylinders are made of aluminum alloy. Xie Yan can't find aluminum for the time being, so he can only replace them with other materials. The accuracy will definitely decrease because of this, but it is enough for this era.
The optical reading device is not required, but Xie Yan still wants to try it. Instead of magnifying the scale twenty times, it should be okay to magnify it three to five times, right?
There is not much else to say, there are three agate knives, an agate plate, a weight hammer, and some debugging devices.
Xie Yan didn't know how to control the knob, because he didn't see the internal structure, so he had to rely on his own little brain to design it.
Including the optical reading device, you must also design it yourself. The principle is very simple, even a junior high school student can understand it, but it is very labor-intensive to make.
The more design, the more headaches.
The day before school started, Xie Yan found his mother: "Mom, I'm not going to study for the time being. I'll study the agate balance later. Can you help me contact a craftsman who can grind telescope lenses and a craftsman who knows micro-carving skills?"
, I also need a skilled jewelry craftsman. Well, I also want to buy the best balance now."
So, don’t be a scientist if you were poor in ancient times. Building a high-precision balance was quite expensive.
After listening to his son's various requests, Wang Yitong forcefully swallowed back the curse words.
Oh, forget it, my son broke his head.
Wang Yitong did not scold her son, nor did she go to various craftsmen. She decided to let her son recuperate at home for a few days.
Xie Yan didn't know that his mother was perfunctory and happily continued to design various parts.
Several days passed and the craftsman still hadn't been found. Xie Yan finally realized something was wrong: This mother was fooling people!
…
"Liu Lang is still not clear-headed?" Xie Yiqin asked.
Wang Yitong said: "He has been drawing drawings in the study. I have also looked at those drawings, and they don't seem to be scribblings. Is he really studying the scale?"
Xie Yiqin said: "I'll go take a look."
Today is a ten-day holiday, so Xie Yiqin rarely relaxes.
He came to the children's study room. Xie Yan was writing and drawing, Xie Wan was doing homework, and Xie Kan went out with his classmates.
"Are you still designing the balance?" Xie Yiqin asked.
Xie Yan sighed: "Oh, you don't believe it, and the craftsmen won't help me find it. I always have to prove myself. Why am I writing a paper for a physics journal?"
"Weren't you studying a chemistry journal last time? Why are you writing a physics paper this time?" Xie Yiqin felt that his son was stuck with a hammer and a stick, and he had to stick to everything.
Xie Yan explained: "This physics paper is also related to the study of balances. I proposed a damping concept that can be applied to various machines. Current carriages use spring dampers. If suitable materials can be found, it can actually be
Add dampers to absorb shock. The same goes for trains.”
"Is it true that it can reduce the vibration of carriages and trains?" Xie Yiqin was quite surprised.
Xie Yan said: "Of course it is true. If my paper is published, it will prove that I am really doing research. Then you will have to help me hire craftsmen."
Xie Yiqin smiled and said: "If you can publish a paper in a physics journal, I will get you whatever you want."
"It's a deal," Xie Yan said.
Xie Yan not only wrote one paper, but three papers in a row, all about balance components.
Xie Yiqin stood aside and watched, wondering what his son was writing.
At this moment, Wang Yitong quickly walked into the room, holding a letter in his hand: "Sent from the Imperial Academy of Kaifeng."
Xie Yan was confused by what he heard. Wasn't his last paper sent to Luoyang?
In fact, the young chemist in Luoyang was frantically writing letters to friends to discuss "Theory of Molecular Science" and completely forgot to send a rejection letter to Xie Yan. The letter in front of me was sent by Zhu Shirong.
In the next period of time, Xie Yan will probably receive many letters from chemists.
After Xie Yan opened the letter and read it, he handed it to his father: "This is a letter from the vice president of Kaifeng Taixue College of Chemistry, discussing the details of molecular theory with me, and inviting me to Kaifeng Taixue for face-to-face communication."
Xie Yiqin hurriedly read the letter and was already stunned before he finished reading it.
Seeing that her husband was stunned, Wang Yitong snatched the letter away. After reading it, he was overjoyed: "My son is actually a chemistry prodigy!"
Hearing this, Xie Wan dropped her homework and ran over to ask, "What's wrong with Sixth Brother?"
"Your sixth brother has outstanding knowledge and was invited by the vice president of Taixue." Wang Yitong was very happy.
Although Xie Wan didn't know how serious this matter was, she still felt that her brother was very powerful. She jumped up and said, "I'm going to tell my teachers and classmates. They will definitely be jealous of me!"
Xie Yiqin finally calmed down: "Can your damper really reduce the vibration of carriages and trains?"
Xie Yan said: "We need to find suitable materials."
"Then write it down quickly and I'll apply for a patent for you. Don't let others get ahead of you!" Xie Yiqin said.
Xie Yan had no choice but to explain: "Damping is a physical phenomenon and I'm afraid it cannot be patented. How to make a damper will take a lot of effort. And different dampers have completely different structures."
"Then apply for a patent for the damper you use on the balance." Xie Yiqin said.
Xie Yan smiled and said: "You can't make much money even if you apply for a patent for the air damper of the balance. How many people can use this kind of damping balance in the entire Ming Dynasty? They can make it themselves, as long as they don't take it
If you sell it for money, you won't infringe the patent."
Xie Yiqin stopped talking, as if he had lost a hundred thousand coins.
He read Zhu Shirong's letter again and finally said: "What kind of craftsman do you want and what materials do you want to use? I will send someone to get it immediately!"
…
Xie Yan has not yet made the damping balance, and the paper on damping has been sent to Luoyang.
Nie Qi is the second review editor of a physics journal. He is doing nothing that day. After all, there are only so many physicists in the country, and important papers are not received every day.
"Sir Nie, there is a good article." Sun Sanyi, the first edition editor, walked over quickly.
Nie Qi took the paper and read the title: "Damping? This name is very weird."
Sun Sanyi said: "It is very useful."
Nie Qizai read it carefully, and after reading it, he said: "Get two springs!"
Sun Sanyi immediately went out to call someone and found two springs from the laboratory and a few weights that could be hung.
This experiment is very simple and can be completed in a few minutes.
Of course, to get more accurate data, more detailed experiments are needed.
Nie Qi sighed: "No one has discovered such a common physical phenomenon for hundreds of years."
"The more common they are, the more they are ignored," Sun Sanyi said. "The author of the paper proposed that dampers can be used in carriages, trains, and large ships. Especially trains and ships. If someone can build a damper, the Royal Society will probably
Award a gold medal. Create at least a baronet, maybe even a viscount."
Nie Qi shook his head: "The principle is very simple, but it is difficult to make something. This paper will be published in the next issue, and I will personally write to the Ministry of Industry."
"President Geng..." Sun Sanyi reminded.
Nie Qi said: "The papers we received are none of his business."
Sun Sanyi stopped answering because he did not want to get involved in this kind of struggle.
Nie Qi asked: "It seems that the author of this paper is not our member?"
Sun Sanyi said: "He did not mark the membership information on the envelope, so he is probably a private scholar who has not yet joined the membership."
Nie Qi sent Sun Sanyi away and replied to Xie Yan himself.
The general content is to ask Xie Yan to prepare resume information, including more specific identity information, research results, etc.
Xie Yan can become a full member of the Royal Society of Physics just by discovering the damping phenomenon.
Moreover, once someone invents a vehicle-mounted or ship-mounted damper, the value of Xie Yan's paper will continue to rise.
By then, Xie Yan will be at least a baron!
Of course Nie Qi also has selfish motives, the papers he reviews, the members he recruits, and the Ministry of Industry he reports to. Hehe.
"Dong dong dong..."
There was a knock on the door.
Nie Qi looked at Sun Sanyi standing at the door: "Why are you back again?"
Sun Sanyi said: "Can I add a damper to the balance?"
"What is used to apply damping?" Nie Qi asked.
Sun Sanyi said: "Air."
Nie Qi was startled, slapped his thigh and said, "Wonderful!"
Sun Sanyi smiled.
Nie Qi said: "Let's do it together, and you must not announce it to the outside world. By the way, suppress that paper and wait until we get the damping balance out."
