Chapter 411 Buying Books
When the comrades from the original research institute heard this, they were overjoyed.

I originally thought that I could just take a look at the calculation manuscripts and learn a lot of knowledge from them, but I didn't expect that Chief Engineer Gao would take time out to study this thing despite his heavy workload, and did not rest on his laurels as the initiator.

As for what Chief Engineer Gao said about "communication and exchange", just listen to it. They are just trying to save face for us. What is there to communicate? It's more like one-sided guidance.

After Gao Zhendong finished speaking, he turned and walked towards the safe next to him. He still had to pretend.

The two comrades turned and faced the door.

Gao Zhendong did not take out the entire book, as that would have been too much. If one calculated the normal time for such a thick book, he would not be able to copy it so quickly even if he just copied it, let alone use his limited spare time to do difficult research.

He took out some manuscripts from the storage, closed the safe in a pretentious manner, and turned to walk towards his comrades from the original research institute.

"Here, here are some of my recent research results. I hope they are useful."

Gao Zhendong handed the manuscript to the two of them, who quickly took it and put their heads together to look at the table of contents. The manuscript contained quite a lot, about 100 pages.

"It mainly includes the ring laser self-consistent equation, which is a semi-classical theory. It also discusses the traveling wave laser self-consistent equations, as well as the exact state approximate solutions and locking effects of the ring laser self-consistent equations. By the way, some error effects are also theoretically analyzed and predicted."

"By the way", listen, this is human language. You should know that if you want to analyze and predict errors, it must be possible after in-depth research.

The hands of both men were shaking a little. These things sounded like the most basic theories of laser gyroscopes. With this, it was even better than Gao Zhendong telling them how to implement a laser gyroscope right away.

The latter can only know the fact, but the former can know the reason behind it.

Once any research topic involves equations or systems of equations, it means that it has begun to enter a deeper realm.

Looking at the catalog of the manuscript, in addition to the major headings mentioned by Gao Zhendong, each major heading is divided into several contents. Although they are all theories, the content is very detailed.

The entire manuscript is handwritten and looks very neat. It must have taken Mr. Gao a lot of effort.

Computers at that time were still not capable of editing formulas, drawing graphs, or making tables, so this kind of manuscript had to be handwritten.

"Chief Engineer Gao, let's go back and read your masterpiece carefully. Once we have learned it, I think many of the current problems will be solved. Then we will summarize the new problems and come to visit you again."

Gao Zhendong nodded. "Okay, the answer to your question about oscillating lasers is in here. And I've calculated that, under certain other conditions, the output of the system is proportional to four times the enclosed area of ​​the annular optical path and inversely proportional to the wavelength of the laser used. You can read it with this concept in mind."

Although this inference is in the manuscript and is not even the core content, we can first give a qualitative concept.

Gao Zhendong himself doesn't fully understand what's inside yet, so it would be best for them to go back and study on their own first. Gao Zhendong also has to study on his own, but he will definitely learn faster than these two.

Moreover, before they have learned the theoretical content of the previous part, it is really impossible to communicate with them about the other parts of the book. They can't understand it at all.

The two comrades from the original research institute, with a feeling a bit like Tang Monk returning to the Tang Dynasty after obtaining Buddhist scriptures, very carefully took Gao Zhendong's manuscript back to the original research institute.

As soon as they returned to the unit, they ran to find the chief engineer.

"Chief Engineer, we are back from our quest, and this time we got some good stuff."

The chief engineer of the original research institute smiled and said, "It seems that we have gained a lot this time? Look how happy you are."

"Well, Mr. Gao is indeed the best in laser science. He has done a lot of theoretical research based on the ideas from last time, and he has also selflessly shared his research results with us for us to learn from. Take a look~~~~~~"

Since Gao Zhendong was not around, the title naturally changed back to "Teacher Gao".

As they talked, they took out the manuscript on the principles of the laser gyroscope and were about to hand it to the chief engineer.

"You are so confused! You two should keep this thing to yourselves and look at it. Don't give it to anyone, including me and the director!"

When the chief engineer saw their inappropriate behavior, he spoke harshly and scolded them.

The two of them then realized that this behavior was a bit reckless.

Maybe Teacher Gao is selfless and doesn't care much about the manuscript, but the National Defense Committee definitely cares about it. It's okay for the two of them to take a look at it for work purposes, but it would be taboo to show it to others.

It's all Teacher Gao's fault. Such an important thing seemed so nonchalant and unimportant to him, causing the two of us to subconsciously relax our vigilance.

The two of them quickly put away the materials and turned to the confidential area to look at them. Moreover, they could not leave there until they returned the materials to Teacher Gao.

That is to say, they are honest. If it were the people in the computing institute, they would definitely want to collect it. Director Li and Chief Engineer Chi: Don't cue!
-
The comrades from the original research institute received half of the book given by Gao Zhendong, while Gao Zhendong himself received a large pile of books.

It was none other than the batch of medical books that he had commissioned his comrades in the propaganda department to purchase.

The propaganda department was very open and probably heard from some unknown channel that Gao Zhendong received a lot of royalties. They did not even ask Gao Zhendong for funds first, but directly transferred nearly a thousand books from the warehouse of the Xinhua Bookstore headquarters.

When it comes to requisitioning books from Xinhua Bookstore, there may be no department more convenient than the Propaganda Department.

"Chief Engineer Gao, these are the books you requested. Please check if there is anything you want to adjust. If there is no problem, please give me your address and I will send it directly to you."

On a vacant lot in front of the office building of the Third Factory, several tricycles were parked there. Each tricycle was covered with tung oil cloth to prevent it from raining in case of a sudden change in the weather.

The young man sent by the Propaganda Department rode one bicycle, and two other comrades rode the other two.

Gao Zhendong touched the tung oil cloth with some curiosity. There were not many plastic sheets at that time, and this thing was the best to protect against rain. He had only heard of it in his previous life but had never seen it.

There is no need to order. We cannot order all of this stuff in a short time. They can deliver it first, and you can check it at home. If anything is missing, you can buy it when you have time. The big stuff has been taken care of, so you don't need to trouble comrades with small matters.

"Thank you very much, comrade. How much? I will give you whatever you want."

"Chief Engineer Gao, you're welcome. I'll give you a bank account number. You can deposit money into it later and just indicate that it's for the purchase of books."

After the propaganda guy finished speaking, he handed a stack of papers to Gao Zhendong. The first sheet had the account number and amount, and the following had the list and price. The total price seemed quite cheap to Gao Zhendong, just over 6000 yuan.

However, ordinary people would probably be shocked when they see this number, as they cannot save so much money in their lifetime.

The main reason is that there were nearly a thousand kinds of books, and Gao Zhendong bought two copies of each kind, which means the amount of money is huge.

But for Gao Zhendong, this is not a big deal.

Not to mention the distant past, just the recently published physics popular science book, the amount I have received now is almost enough to cover half of this number.

Gao Zhendong put the note away. Before he could tell the address, Xie Jianye, who had arrived at some point, came up to him and said, "Chief Engineer Gao, I'll take it back. Comrade, I won't bother you anymore. Just follow me and unload the things. We'll take care of the rest."

In the factory, when there were many strangers around, he no longer called Gao Zhendong "Platoon Leader Gao".

The young man in the propaganda department looked at Gao Zhendong, who nodded and said, "This is a comrade from our factory's security department. Just do what he tells you to do."

Several people followed Xie Jianye on bicycles.

When Gao Zhendong got home from get off work, the pile of books was already lying in his bedroom. Some of them had been put on the bookshelf by Lou Xiaoe, but the number was too large to put them all away.

Lou Xiao'e came over and took his bag, asking curiously, "Zhendong, why did you buy so many books?"

Gao Zhendong drank the water and said with a smile: "But you can use it. You are going to study medicine soon. I asked the comrades in the cultural department to buy all the publicly published medical books. This way it will be convenient for you to look up anything you want."

Lou Xiao'e didn't finish unpacking all the books. She didn't expect that all the books were about medicine. When she heard Gao Zhendong was so considerate of her, she leaned over and kissed Gao Zhendong without saying a word.

After the kiss, she felt a little guilty for fear of being discovered, so she shrank her neck and looked out the window with a sly look. There were curtains hanging in the house, and no one knew what she was feeling guilty about.

Looking at the pile of books on the floor and by the wall, Lou Xiao'e said in high spirits: "Zhendong, accompany me to buy a bookcase on Sunday. I want to put all the books away properly. Oh, and I also need to buy some mothballs."

Mothballs are insect repellent and were widely used to prevent moths on clothing before the 90s.

However, the production of this thing is actually not enough. There is an artificial synthetic substitute, but it is best not to use that thing.

"Well, okay, but don't buy the mothballs. They're not good for people. Go find some quicklime and pack them up and put them at the bottom of the bookcase to keep out moisture."

Sanitary balls are naphthalene, the simplest polycyclic aromatic hydrocarbon, which can also repel insects, but is harmful to humans. Quicklime was used by ordinary people to prevent moisture in the early years when there were no household desiccants such as activated carbon.

Lou Xiao'e nodded in agreement, but her thoughts had long since drifted off to who knows where. Shopping really does secrete dopamine, including buying books.

After the couple finished their meal, Lou Xiao'e began to read the books that Gao Zhendong bought for her with great interest, flipping through this one and that one.

Gao Zhendong, on the other hand, was busy taking out a copy of each type of book and putting them together.
