"The Education Department has informed that all major schools will close at 1 p.m., and teachers and students will not go out for the time being. I hope you can understand."
The assistant principal's tone was very serious.
The reason for the temporary cancellation of the academic lecture was mainly due to the sudden outbreak of the Marco Polo Bridge Incident, which was accompanied by the organization's declaration that was immediately broadcast across the country. After research, the school had to make the decision to cancel this academic lecture.
First, it is not in line with the current tense situation. Second, after the Marco Polo Bridge Incident, the whole city of Peiping entered a state of martial law. All teachers and students of Peking University, Nankai University, Yanda University and other schools were closed and unable to attend.
"It's okay, I can understand that national affairs should be put first." Yu Hua was not surprised by the news. He had no emotions in his heart. He nodded and responded.
"The principal said that he will hold another academic lecture for you after the matter is over. Don't worry." The principal's assistant said softly. He looked at Yu Hua, who looked calm and calm, and was quite impressed. You know, academic lectures are very important to anyone.
They are extremely important to famous scholars.
The temporary cancellation is a huge blow.
"fine."
Yu Hua smiled and nodded.
"Then I'm leaving, classmate Yu Hua. If you have anything, you can come to me and I will try my best to help you." After the notification was completed, the assistant principal turned and left.
"You walk slowly."
Yu Hua stood up to say goodbye.
He sent the principal's assistant to the door and watched him go downstairs. After leaving the nuclear physics laboratory, Yu Hua turned back to the room and thought silently: "It doesn't matter if the academic lecture is canceled. After all, the results of the paper are there. Strictly speaking, for
For me, I just lost an opportunity to show off and establish an aura of authority. Such opportunities are precious, but there are many."
This academic speech mainly explains the asymmetric cryptography theory and some details. To put it bluntly, it is to tell the Chinese mathematics community - starting from today, I, Yu Hua, officially enter the mathematics community as a recommended student of Tsinghua University and become a new mathematician.
If you are dissatisfied, then find out the flaws and fatal loopholes in asymmetric cryptography theory.
Obviously, with the support of three mathematical giants from the Institute for Advanced Study in Princeton, asymmetric cryptography is impeccable.
As for whether this opportunity is valuable?
It is indeed very precious.
But Yu Hua believed that he definitely had more than this opportunity. After all, this opportunity was created by himself and was not given by anyone.
In one sentence, there are two kinds of values in the world. One kind of value is to wear a very expensive watch to show that one is worth a hundred times. The other kind of value is my value, an inexpensive watch, because I wear it.
After passing it, it is worth a hundred times.
Yu Hua believes that opportunities are also divided into two types, one is the opportunity given by others, and the other is the opportunity created by oneself.
In the academic field, anyone who wants to climb to the top and become a strategic scientist with important influence on the entire civilization must rely on the latter.
"In that case, let's concentrate on work. By the way, we have to find the organization first." Yu Hua quickly abandoned the complicated thoughts in his heart and concentrated on the current work. When he was about to take the materials to the mechanical engineering laboratory,
Suddenly I remembered the technical briefing the night before yesterday.
Now that the theoretical research and development of oxygen top-blown converter technology has been completed, the remaining work is to construct the steelmaking plant design drawings and manufacturing links. No matter what, it is inseparable from the support of the organization.
The steelmaking plant design drawings need to select the site first, and then discuss the design. Manufacturing experimental air separation equipment, oxygen lances and converters requires a lot of money, manpower and material resources, and all of these need to be completed in the base area.
Without the support of the organization, all ideas and base industrial base plans will become a fantasy.
Just as he was told, Yu Hua washed up briefly, went to the cafeteria to have breakfast, then quickly came to the west gate of the school, went out to the right, and waited quietly under the eleventh banyan tree.
Not far away, Yang Xiu, who was on call 24 hours a day, looked around and carefully observed whether there was any suspicious person following Yu Hua within a radius of fifty meters. After confirming that there was no mistake, he appeared.
"Mr. Yu Hua." Yang Xiu, who was wearing a gray vest and dressed as a worker, came to the big banyan tree and spoke respectfully.
"I need to meet with Butler Liu as soon as possible. This meeting is also attended by Professor Zhuang Qianding of the Department of Mechanical Engineering at Tsinghua University. The location is nearby and the matter is very important." Yu Hua kept the story short and went straight to the point, giving Yang Xiu his request.
Hearing this, Yang Xiu felt the urgency in Yu Hua's tone and immediately nodded: "Yes, I will contact Butler Liu immediately. Please wait for five minutes."
The words fell and he left.
Yu Hua watched Yang Xiu leave and stood there, waiting quietly, looking left and right with his eyes to see if there were any suspicious persons following him or intelligence personnel monitoring him.
Yu Hua has always had a very high anti-reconnaissance awareness and behavior. As long as he discovers the whereabouts of any suspicious person while out, he will immediately end the day's trip, whether it is meeting Xu Rui or going out to mail a letter.
From a theoretical point of view, the people who are most likely to follow or monitor him are only people from the Blue Clothes Club, who are most likely to monitor whether he will leak information on deciphering the red secret.
Fortunately, after such a long period of observation and counter-reconnaissance, Yu Hua did not find anyone following or secretly monitoring people. Tracking and surveillance in this era were very backward. It was mainly done by one person or multiple people. Anyone with a little bit of counter-reconnaissance awareness could do it.
Can feel it.
Of course, it is by no means ruled out that Boss Dai ordered the Blue Clothes Club to use top ace spies to spy on him secretly.
only……
Yu Hua didn't think that he, a mere high school student, deserved to be treated like this by Boss Dai.
As for the vest Zhang San, Yu Hua believes that Lan Yishe has not discovered the relationship between him and Zhang San. The probability of this judgment is 80%, and the remaining 20% is that Lan Yishe has discovered the relationship between himself and Zhang San.
Third, the relationship between organizations is playing a long-term role in catching big fish.
There are any possibilities. Out of rigorous scientific thinking, Yu Hua will never make a conclusion.
After all, he risked exposing his identity and established contact with the organization represented by Lin Wan through almost clear text messaging.
Yu Hua cannot guarantee whether the two technical documents will be leaked during this process.
Based on the first judgment that there is an 80% probability of not being discovered, the current logical relationship between the identity and the vest is roughly as follows - the Blue Clothes Club only knows its true identity, but does not know that the vest Zhang San has leaked red secret information to the organization, and only thinks that Zhang San is
Author of "Chinese Mechanical Drawing".
The organization knows Ma Jia Zhang San, but does not know his true identity.
The Japanese may know Mr. Zhang San, but they don’t know his true identity.
If it is the second 20% probability of taking the long term to catch the big fish, then Blue Clothes Club is the real super winner. His small actions and behaviors, as well as all technical information, have already fallen into the hands of Blue Clothes Club, and the other party is waiting to collect them.
net.
As for which type the actual situation belongs to, Yu Hua prefers the former.
Yu Hua believes in the modern counter-reconnaissance skills and awareness mastered by hardcore military fans, and he also trusts his own intuition and judgment.
Having said that, as for why the information was transmitted in a nearly clear text way in the first place...
The reason is very simple. It is not that Yu Hua cannot design complex password transmission methods to ensure information security, but that too complex password transmission methods will make information exchange difficult.
In short, the organization may not be able to decrypt it.
Choosing to use the postal system to send technical data is an optimal solution with high risks and high returns, and Yu Hua can afford this risk...
The worst case scenario is to give up the plan to study abroad and the goal of being a strategic scientist, take root in the base area, and directly pursue the path of weapons research and development.
Time passed by minute by second, and about five minutes later, Yang Xiu's figure appeared on time.
"Mr. Yu Hua, Butler Liu has already left. The meeting time is at six o'clock. I will pick you up and go to the meeting place." Yang Xiu spoke clearly and said quickly.
"good."
After receiving this reply, Yu Hua nodded, turned around and walked back without explaining too much.
…
"Zhuang Qianding, born in 1902, native of Qingpu, Shanghai, is the chairman and full professor of the Department of Mechanical Engineering at National Tsinghua University. He has dual master's degrees from Cornell University and MIT. He is mainly engaged in machinery, chemical industry, metallurgy, and aviation power.
Research in electric power and other fields.”
"Graduated from the Department of Mechanical Engineering of Nanyang University in Shanghai from 1920 to 1924, with a bachelor's degree in mechanical engineering."
"From 1924 to 1925, he served as technician of the Ministry of Communications and assistant professor of Jiaotong University."
"Graduated from Cornell University Graduate School in the United States in 1925-1926 with a master's degree in mechanical engineering."
"Graduated from the Massachusetts Institute of Technology in the United States from 1926 to 1928 with a master's degree in chemical engineering."
"In the four years from 1928 to 1932, he served as an assistant researcher at the Massachusetts Institute of Technology, an engineer at the Boston Sway Engineering Company, an engineer at the Edison Company, and an engineer at the Chicago area power plant."
"In 1932, he returned to China and personally founded the Department of Mechanical Engineering at Tsinghua University. He served as the acting preparatory director and technical consultant for the Machinery Manufacturing Factory of the National Resources Committee, and independently designed and built the Tsinghua 15-foot wind tunnel project."
"The above is the identity information of Professor Zhuang Qianding."
In a Ke Lai teahouse in the north of the city, a young person held the latest collected reports and gave out Professor Zhuang Qianding's identity information and resume one by one.
After reading all the information, the young comrade who was affiliated with the Northern Special Branch immediately left the conference room.
In the room, Liu Wei, who had put down a lot of important work, and Lin Wan, who had been working in the organization, were sitting.
Unlike Yu Hua, who reported to school as soon as he received his university notice, Lin Wan has been working within the organization since the completion of the Yu Seven Towers project and has not yet reported to Peking University.
"Comrade Qingluan, this Professor Zhuang Qianding is really a great talent. He has obtained one degree after another, various engineers, and has more ink in his belly than ten of me." Liu Wei took out a cigarette.
He lit it, took a sip, and spoke slowly.
"Comrade Professor, as far as I know, Professor Zhuang is one of the best professors at Tsinghua University. How come he met with us together with Yu Hua?" Lin Wan said.
"This is also a question in my mind. I probably have a guess, but I dare not say it." Liu smiled and said.
