Back to the Republic of China to be a editor

Tang Hua opened his mouth wide and looked at the heavy silver dollar in his hand, "Mr. Dong...it's unnecessary, really unnecessary, this is what we should do. The works of my father and I can have so many readers in Yan'an... So many bosom friends, I think this already makes me very happy."

"Young Tang, don't refuse. This is also our consistent principle. If you work hard, you should get paid. If you don't get paid for your hard work, wouldn't you be exploited by us?" the chairman said.

Seeing what Mr. Dong and the chairman said, Tang Hua knew he couldn't refuse.

Looking down at the list, hey, Mr. Dong's handwriting.

The strokes are neat, steady and heavy official script, and the final inscription is "Dong Biwu, Bank of Shaanxi-Gansu-Ningxia Border Region"

It is exactly the same as the font of "People's Bank of China" on the RMB...

"Okay, I'll take it... this list!" Tang Hua said, "Mr. Dong's handwriting must be kept! Silver dollars..."

Tang Hua opened the paper seal, took out a silver dollar and put it in his pocket, and pushed all the others to the teaching director next to him, "I took the silver dollars, but I decided to use these silver dollars to buy some pencils and notebook paper, and put them in the lecture hall." , so that the students in class can write down what they hear, and they can also write down the questions they don’t understand and hand them to me, and I will answer them. Please ask the director to purchase on my behalf.”

"That's it," Dong Biwu put the notebook in his briefcase, and put the pen in his chest pocket. "Then we'll go back to our respective houses first. We'll meet and chat after dinner tonight."

……

After Tang Hua packed up his things, he walked slowly from Yan'an University to the cave where he lived.

Three meters behind him, a middle-aged man in a leather jacket with round glasses and a peaked cap followed Tang Hua.

"Mr. Kang, are you on your way?" Tang Hua turned around and asked.

……

Another way to go.

"Minister Kang, is our journey so smooth?" Tang Hua asked again.

……

"Okay, okay, don't ask." Kang Sheng said wearily, "I accept the mission of the organization, and I will follow you all the time. Prevent you from contacting other irrelevant and suspicious people."

I knew it.Tang Hua thought.

"Oh... okay. I understand. Mr. Kang, but the Democratic League also has three permanent representatives in Yan'an."

"They don't chat with the chiefs every day. It's good for you, the chiefs come to chat with you."

"...That makes sense. But I still think it's enough for ordinary comrades in your ministry to come."

"Then there will be one more person who may know something that shouldn't be known from you." Kang Sheng said, "I can't censor you, you are not a party member, and you don't have your file, so you can only keep doing this. Please... "

Chapter 6, didn't understand anything but still very rewarding

"Sisters, let's go to Mr. Tang's "Development Trends of Science and Technology and Military Equipment" class tomorrow afternoon?"

"This class? It seems that many male students are crowded to listen to it, but we don't study science and engineering, so we probably don't understand it. Why should we go?"

"Why? Let me tell you, Mr. Tang who is giving the lecture is very handsome!"

Yan'an University, the former regular class of women's university department.

Yan'an University was established through the merger of many universities, including China Women's University.This university established by our party to train women cadres has trained more than 1000 graduates during the Anti-Japanese War.The women's university is divided into ordinary classes, advanced classes, Shaanxi dry classes and special classes.The ordinary class is for normal college girls, the advanced class is for female cadres of the Red Army who have participated in the Long March, the Shaanxi Gan class is for training female cadres in the Shaanxi-Gansu-Ningxia Border Region, and the special class is for the Red Army who have participated in the Long March but have a relatively weak cultural foundation Female cadres and soldiers.After the merger and establishment of Yan'an University, men and women took classes in the same class regardless of faculties. However, in terms of accommodation and management, girls from the former women's university were still listed as women's departments by the Academic Affairs Office in the logistics category. With the division of special classes, get together to live and live.

The girl who encouraged the girls in the same dormitory to go to class with her was Qiu Honghong, a native of Mizhi.I went to listen to a class given by Tang Hua, and when I came back, I repeatedly nagged and persuaded the other 7 girls in the same dormitory to also attend the class.Qiu Honghong stayed in Amway for two days in a row. The girls in the same dormitory bothered him at first and nagged him, but later they were convinced.

"Handsome? How handsome is he?" Xiao Man answered, "Did you wear a croissant on your head when you were giving lectures?"

"Don't mess around here," Qiu Honghong said, "Don't you know how handsome you are after going to a class?"

"I heard...many of our school's teachers also sat down to listen to the lectures. How many times have the chairman and the commander-in-chief come here?" Zhao Zhaodi, who was in the same dormitory, asked Qiu Honghong.

"Yes, yes, the teacher and the dean occupy the first row of seats."

"Then why don't we listen to it once?" Zhao Zhaodi said.

……

At 1:45 p.m., eight girls in the dormitory walked into the academic hall led by Qiu Honghong. At this time, there were not many vacant seats in the classroom.The girls searched for a long time before deciding on a place to sit, but it was no longer possible for 8 people to sit together in a row.

"Wow, Teacher Tang is really handsome..." Xiao Man's eyes sparkled.Looking at the girls in the same dormitory on the left and right, they almost have the same expression.

On the podium, Tang Hua saw that the time was up, and said:

"Okay, time is up, so let's start our class today. In the last class, we talked about information technology. In fact, information technology can be divided into several different stages: pre-mechanical age, mechanical age, electromechanical age and now it is coming The electronic age. What exactly is information technology? Is there one or several concise axioms or theorems that support information technology to become a complete system? Yes.

"The content of today's lecture may be a little deep. Students sitting in the back, I hope you take good notes...I don't understand now, but I will understand after reading the notes slowly."

"In the first class, I mentioned a term: information energy. In fact, to be precise, it is the rise and fall of energy carrying information, that is to say, it is similar to the concept of entropy."

"In the field of thermodynamics, the concept of entropy (entropy) has long been used to calculate the disorder in a system, that is, to calculate the degree of chaos of the system. Entropy is defined by increment, and the formula is dS=(dQ/T) r, if the process is irreversible, then dS>(dQ/T)r. This is a very simple formula, you should have learned it in school, so I won’t repeat the explanation.”

The girls had blank expressions on their faces.

"Oh my god, what is Teacher Tang talking about?" Feng Xiaoting whispered in Xiao Man's ear.

Xiao Man stared blankly at the podium for a few minutes, then suddenly lowered his head, took a pen and began to copy the contents on the blackboard and the curtain. "Don't worry about what Teacher Tang said, write it down first," Xiao Man said, "Didn't Teacher Tang say it, I don't understand it now, and I will understand after reading the notes slowly."

In fact, the boys sitting in the academic hall, except for a few students studying chemical engineering and physics who can barely keep up with the rhythm, the rest of them have almost the same expressions as the eight girls.Moreover, after the confusion passed, the boys also opened their notebooks one after another, and began to painstakingly copy the contents on the blackboard and the curtain with pens.

On the contrary, the teachers and researchers of the Academy of Natural Sciences in the first row scratched their heads with excitement.

"I will for the moment refer to the average amount of information contained in each received message as information entropy. Here, a 'message' represents an event, sample, or feature from a distribution or stream of data. Oh, and entropy is best understood as uncertainty rather than a measure of certainty, since more random sources have greater entropy..."

"According to Boltzmann's H theorem, we define the entropy value Η (Greek letter Eta) of a random variable X."

……

"...It can be seen that when the value range is {x1,...,xn}, E(X)=E【i(X)】=E【-In(P(X))】. Among them, P is the value of X Probability mass function, probabilitymassfunction. E is the expected function, and I(X) is the amount of information of X, also known as self-information. I(X) itself is a random variable. When taken from a limited sample, the formula of entropy can be expressed For H(X)=∑iP(Xi)(xi)=-∑iP(Xi)LogbP(Xi)"

……

Now, the chemical engineering/physics students sitting in the academic hall are the same as others, staring blankly at the blackboard, two lines of hot tears streaming from the corners of their eyes, silently began to copy notes, and gave Tang Hua an oral lecture without showing it on the slide projector The content of is also shorthand.

The teachers and researchers in the first row began to think hard. Some of them were quick-witted and nodded desperately after they figured it out. If they couldn't figure it out, they asked Tang Hua questions nearby.

Xiao Man's original plan was to write down the content of the lecture first, and after the lecture was over and started to answer questions, he would pick a few questions from it and pester Teacher Tang to answer them. Things came down and I found myself not knowing what to ask.

On the podium, Tang Hua was very relaxed.

Tang Hua also saw the students sitting in the conference hall crying and taking notes, and a smirk could not help but appear on the corner of his mouth.

Today, because of the emergency situation in the Central Plains Military Region, the members of the Standing Committee did not attend the lecture until the afternoon after the meeting in the morning, and this lecture happened to be a bunch of content that the big guys thought was not very friendly... But very Importantly, by pulling Shannon's information theory and information entropy together, we will have the most solid theoretical system as a basis in the future.In short, this knowledge is told to the teachers and researchers in the first row.

"I will stop here for the time being with the basic theoretical knowledge. In fact, in this field, I still hope to open up discussions. I will answer them one by one, so that everyone's knowledge system can go deeper in this area."
