Back to the Republic of China to be a editor

After reading the beginning of the paper, Vavilov put down the magazine, "Can you believe this is the physics special of the Bulletin of the Academy of Sciences?"

Zhou Xuan shook her head, she didn't know. "Then isn't this article amazing?"

"Oh, great, very powerful." Vavilov remembered that at the report meeting, it took Tang Hua a few minutes to express the information entropy formula clearly. When he said these words again, the venue fell into silence.Then, mathematicians and physicists began to discuss whether information entropy is entropy in the physical sense; if it is true entropy, then whether there is a formula for mutual conversion.The most tiring thing in the meeting was the translation. If it weren’t for the participants and two or three people who were proficient in Chinese, the guest scientists and Tang Hua would have to work hard on the spot for the mutual translation between the dialogues between scientists and Tang Hua.

"But there is one thing about Tang Hua that is incompatible with us traditional scholars of the Academy of Sciences," Vavilov said. "Tang Hua is particularly good at understanding the psychology of high-level leaders, and even consciously pleases them. Yes, although he himself and Our Academy of Sciences has obtained huge resource returns, but this is really not our way of doing things. After finishing the reports on physics and cybernetics, Tang Hua made a report on the development of computer technology in the United States. The final development of this report, Get everything out of control..."

After pouring half a glass of vodka, Vavilov continued to recall Tang Hua's speech on stage three years ago.

"You should now think that computers must be used for scientific research, for the calculation of the most cutting-edge research, and use it to calculate the numerical solutions of the most complicated differential equations to four, five, and six decimal places... No, the computer's And that's not all. Why can't we use it to do some really simple calculations?"

Tang Hua wrote a series of numbers on the blackboard. "This is a 15-digit number. We input the number into the computer and perform logical calculations on the number. If the fifth to eighth digits of the number are greater than or equal to 1926 and less than or equal to 1928, the judgment is 'yes', not in this range, Then the judgment is 'No'. It is a very simple logical judgment. The only difficulty is that we need to make a logical judgment on 1.67 million such 15-digit numbers. Why is it 1.67 million? This is the total population of the Soviet Union. Why do we make this logical judgment? This is to obtain the total number of service-age personnel. Assuming that the computer can process 2000 15-digit strings per second, then we can use one person, one computer, and about two days to complete a statistics of the potential of the national soldiers of the entire Soviet Union."

The political committee member of the Academy of Sciences, who had been sitting in the audience for 5 days, was no longer sleepy, his eyes were shining and he was scratching his head.On the second day, Tang Hua found that there was an extra row of people sitting in the audience, most of whom were from the Soviet National Defense Committee and Military Service Committee.

"There are about 570 million distinguishable products in the Soviet economy, involving agriculture, light industry, heavy industry, military equipment, literary and artistic products, etc. On the basis of data processing by computers, the national economic information system consists of the following elements: information Resources; national information network; information technology application; information security... The essence of management is the acquisition, processing, processing, circulation and feedback of information. At present, there should be an information source for the planned allocation of national production by the Soviet Planning Economic Commission The process, I don’t know if everyone here can add..."

Political commissar: "I understand. Tomorrow I will call the State Planning Commission, the State Materials and Technology Supply Committee, and relevant members of the Ministerial Council."

"In this way, Tang Hua successfully persuaded the officials. In January 1947, the Soviet Union officially launched the National Computer Project." Vavilov said, "On the one hand, the Academy of Sciences and universities have received a lot of extra funds every year, Materials and fame are undoubtedly good things. On the other hand, when Tang Hua revealed all his plans for the future, it made me feel vaguely worried. This may be a gloomy future where the state controls all corners. However, In the interests of the Academy, I cannot express this doubt. I am not alone in my opinion."

"Is he a genius or a devil? Or, is he both a genius and a devil?"

……

In fact, there are some things that Vavilov himself does not know.And Tang Hua didn't want to say it.

After the report on the last day, Secretary Gong, who followed Tang Hua back to the hotel, was so excited that he couldn't help asking Tang Hua quietly: "Comrade Tang Hua, the computer age means that the planned economy will become perfect? ​​At that time, socialism will be perfect." Capitalism can be defeated once and for all, right?"

Tang Hua: "No."

Before Tang Hua crossed over, in Chile in that world, Project Cybersyn, oh no, the trees on Allende's grave could be used as sleepers...

Moscow region, Dubna.

OKB-2 "Rainbow" Design Bureau.

Vavilov told Zhou Xuan that Tang Hua has been tinkering with a very powerful weapon here recently.

"Use my car to drive to Dubna, find Tang Hua, and bring him back. Let's say that Dean Vavilov wants to drink with him."

There are no murderous weapons in the "Rainbow" design bureau, only a few tall gray buildings, and the stone wall columns reveal a sense of coldness and strength.

"Sorry, Miss Zhou Xuan, Tang Hua is not here." The old lady who received Zhou Xuan answered the phone and said politely.

"Ms. Anastasia...then, do you know where Tang Hua is?"

"The magician Tang Hua went to Kiev three months ago to continue his magic journey."

Magician?Zhou Xuan had already heard several different versions of Tang Hua's nickname in the Soviet Union.

"Ms. Anastasia, why is he a magician? Can you tell me what he does here?"

"Miss Zhou Xuan, I am not the chief scientist of the design bureau, nor am I an administrative leader. My job is file management... Before Tang Hua left Kiev, he and the chief designer convened all the leaders above the middle level of the design bureau and released his report on the spot. Results. Although I have nothing to do with scientific research or management, the Archives Bureau is also a second-level subordinate department, so I also received the invitation. This is the only time I saw Tang Hua's work."

Anastasia adjusted her glasses and told Zhou Xuan what she saw that day.

"The results conference was held in the courtyard of the design bureau, in the west annex building. Before the meeting, temporary scaffolding was installed on the outer wall of the annex building. There are 4 floors of aisles for people to walk in. The left and right ends of the aisles on each floor are There are escalators to climb up and down. In front, on the ground more than ten meters away from the outer wall, there is a black object. It looks like a big bee, with two triangular wings spread out, and the head of the bee seems to be A blunt glass window, the 'bee' is connected to a stable platform with mechanisms for pitching and rotating."

"Tang Hua stood in the middle of the open space and said loudly in Russian: 'Today is an extraordinary day, we have opened the door to a new era—the era of intelligent and precision-guided weapons!" After speaking, Tang Hua lit the Torch in hand."

"Following the sound of the humming motor, the winged 'bee' suddenly turned its head, and the glass window stared directly at the torch in Tang Hua's hand."

"Then, Tang Hua retreated to the wall and moved left and right on the ground. The winged 'bee' kept turning its head, and the glass window on its head was always staring at the fire. Then, Tang Hua climbed up to the second floor of the scaffolding, and then Walking, running, climbing down the scaffolding, and then climbing up on the scaffolding... Driven by the motor, the 'bee' precisely controls the pitch and rotation of its head, and firmly follows the things it locks. On the fourth floor of the scaffolding On the next day, Tang Hua threw down the burning torch in his hand, and with the sound of the motor increasing its power, the 'Bee' quickly changed from looking up to looking down like lightning, and finally its neck was fixed at that angle."

"Tang Hua created an elf who worships flames." Anastasia said. "Oh, of course I know its purpose. It can track flames, and of course it can track the chimneys of warships and the engines of fighter planes. In the future, when our rockets are launched, they will find their targets and destroy them. This is probably a smart weapon meaning of the times."

"Thank you, Ms. Anastasia."

Walking out of the "Rainbow" Design Bureau, Zhou Xuan asked the translator of the same company: "Comrade translator, should I take the plane or the train to Kiev?"

Chapter 8, Aixuan

Ukraine, Kiev, Feophinya Convent.

"The fourth computing module has passed the test!" The inspector stuck his head out from behind the two-meter-high cabinet.

Tang Hua raised his hand and made an OK gesture.

"Old Lie, after the memory test passes, the computer can start its first test run. Where's your wine?"

"One, two, three, three bottles are here. Don, are you sure you only want red wine?" The old column—Sergey Alexievich Lebedev opened the drawer of his locker, asked.

The hot summer winds of the Ukrainian Great Plains blow through the former dormitories of the Feofenya Convent.It has been converted into an electronic technology laboratory by the Kiev Institute of Electrical Engineering. In 1947, Tang Hua came here and began to design and develop the first electronic computer in the Soviet Union.In the following two years, Tang Hua will come to Kiev once every two months, at least for a few days, and most of the time, he will stay here for a whole month.

Although the high-level Soviet Union started the development of electronic computers earlier than in history, they did not allocate too much funds and resources at the beginning, and finally handed over the development task to Ukraine. The address selected by the Kiev Electrotechnical Research Institute is this abandoned monastery.But there is good news. This thing belongs to the project participated by the Soviet Academy of Sciences, and its secret level is lower than that of missiles and other weapon projects.

Such a large monastery is quite spacious, but there is no air conditioning...

Tang Hua was dressed in casual summer clothes, with a big white T-shirt on his upper body and a pair of loose slacks.Uncle Lebedev's clothes used to be as meticulous as Colin Firth's, but in the past two years they have become more casual. Now the cuffs of his shirt are rolled up and two buttons are unbuttoned.

"Two years and five months, my big fool is finally about to be born. It's really a long gestation period." Tang Hua sighed.

This computer, code-named MESM, occupies an area of ​​60 square meters, about the size of a small two-bedroom apartment. 3500 vacuum triodes and 2500 vacuum diodes are densely arranged in the cabinet, and more than a dozen cabinets of more than two meters and nearly three meters high form an 8-meter-long, 10-meter-wide, and more than 2-meter-high cabinet in the dormitory area of ​​the monastery. The closed crescent-shaped area, as long as people approach it, they will feel oppressed and... stuffy. MESM is not a gadget. Its power consumption reaches 25000 watts, which is equivalent to more than a dozen induction cookers turning on hot pot at the same time.

"Don, if you hadn't insisted that all the main parts should be mass-produced, the gestation period would not have been so long." Lebedev said, "For half a year, we have been dealing with the planning committee, urging them to arrange factories, determine Technical standards, column capacity plans. Do we really need that many computers?"

Tang Hua smiled, did not answer, and lowered his head on the small table to check the program used in today's trial run again.What I need to calculate today is a system of differential equations, which has been disassembled and reprogrammed into instructions that the computer can recognize.Tang Hua checked the instruction set for the last time, and prepared to make it into a punched paper tape.

"Tang Hua! Tang Hua!"

A female voice was calling Tang Hua's name, and the voice came from far away.The familiar voice made Tang Hua tremble all over, and the pencil fell on the table.

Tang Hua got up and ran two steps, walked out of the MESM work area and looked around.Soon, they saw a petite figure, and after they both found each other, the figure rushed towards Tang Hua.As soon as Tang Hua took two steps, the two hugged each other.

"Zhou Xuan..." Tang Hua didn't know what to say due to the huge surprise and the absence of a preliminary draft.

"Tang Hua, why haven't you come back for three years, woohoo"

"I'm... so far away from you. I'm sorry."

Zhou Xuan's cheek was pressed tightly against Tang Hua's shoulder, tears pattered down on the T-shirt.

"I can come to you"

"I……"

"Why did you write Yang Cong away? I cried for several days when I filmed that part."
