Chapter 36: Hard to hide excitement

News in Cultural Huaguo is not blocked, especially in a place like Yanjing.

At least it is far from being as blocked as outsiders think, unable to access the latest scientific information, and needing to rely on second-hand news transferred from Soviet Russia.

But the Manhattan Project was more than ten years ago, and it is closely related to the surrender of Neon; it is impossible for Cultural Huaguo not to know.

Hearing about the atomic bomb and the Manhattan Project, the middle-aged man soon realized its use, whether it could help the current 596 Project.

Qian Xuesen's DF series intercontinental missiles are certainly important, but the most important project in Cultural Huaguo at present is the 596 Project.

He really couldn't suppress his inner excitement; he understood very well the situation Cultural Huaguo is currently facing, and what it would mean to have an atomic bomb.

At least at present, if Cultural Huaguo has an atomic bomb, it can grasp quite a bit of initiative in negotiations surrounding border issues with Soviet Russia.

Instead of being as passive as it is now.

"That's right, if my judgment is correct, it is the Monte Carlo method.

It was covered up by Professor Lin in the application of high-dimensional integration."

Qian Xuesen excitedly paced back and forth in the large room while smoking, unable to hide his excitement.

In the current Cultural Huaguo, one can know that there is such a method in some academic magazines.

On the one hand, one doesn't know the specific details, and on the other hand, even if you know how others use this algorithm, you don't have the computer to apply this method.

It is too far behind in basic hardware.

So in the past, everyone didn't have the motivation to figure out what this thing was.

And the improved Monte Carlo method is simply a timely rain for the current Cultural Huaguo.

"Look, its application range is too wide, and it can help the entire nuclear bomb research and development process.

The core difficulty of the atomic bomb lies in determining the critical mass of nuclear materials, such as the minimum level of Uranium-235 or Plutonium-239, and how neutrons diffuse, reflect, and trigger chain reactions in fissile materials.

In the past, we could only rely on the Boltzmann equation and experiments to repeatedly try and fail; the cost is high, and the entire cycle is also very long.

And now we can first simulate high-probability neutron paths through simplified geometric models.

Look, Professor Lin introduced the concept of pseudo-random numbers here to reduce the total amount of calculation required.

Yes, I have worked with von Neumann and seen the random number generator he built; how could I not think that pseudo-random numbers can be used to simulate the neutron reflection frequency of different reflection layers.

I finally know why the Soviet Russia atomic bomb explosion could be a full four years ahead of the original plan; they must have known the entire complete Monte Carlo algorithm."

The middle-aged man was dumbfounded; is this thing so powerful? It can save as long as four years.

"President Qian, do you mean that if we master the Monte Carlo method, we can also save four years?" The middle-aged man's voice trembled, and he thought to himself: "No, we must increase the intensity of persuading him to return to the country! Such top talent overseas is really a major loss for us."

Qian Xuesen didn't answer the latter, but continued to talk about the previous problem:

"I don't know how much time we can save, but at least we can significantly reduce nuclear material explosion experiments.

By building Monte Carlo models and introducing pseudo-random number generators to reduce calculation volume.

Perform multiple samplings on neutron life, collision probability, and spatial distribution to quickly estimate critical thresholds under different material configurations. At least it can shorten the nuclear material tests that originally required dozens of times to single digits.

This method must be organized by experts in mathematics to sort it out, and after sorting it out, it should be fed back to the 596 Project as soon as possible.

Not a minute can be delayed!

There are 37 cases here in total, and we must gather the strength of all experts.

The Monte Carlo method can not only be used in atomic bombs, but also in the research and development of DF-1.

This is mainly to create errors through Monte Carlo to optimize the design of the missile's redundant structure and warhead structure, and improve the missile's hit accuracy.

Previously, our planned accuracy was controlled within 3,000 meters; everyone knows very well that this accuracy is very poor.

But after all, we are based on the Soviet Russia P-2 modification; rather than design, it is better to say it is training troops according to their ideas, exercising the talent team, and the DF-1 produced has a large gap with actual application.

But with the Monte Carlo method for structural adjustment, just this one method alone, I am confident in reducing the accuracy to within 1,000 meters."

This is really not wrong; originally, after the DF-1 test launch was successful, there was no follow-up, because this missile had natural defects, and Cultural Huaguo's research and development of this was mainly to exercise the team, and it wasn't until DF-2 that it began to be equipped on a large scale.

The middle-aged man breathed a sigh of relief; only he knew how much pressure they were under. "In this way, the threat from Soviet Russia is about to go bankrupt.

President Qian, when can the DF-1 improved with the new method be test-launched at the earliest?"

And the originally officially equipped DF-2 was decided two months later, and at this point in time, Cultural Huaguo already knew that the Russians had unilaterally torn up the expert cooperation agreement, and 1,390 experts would be withdrawn one after another.

"Half a year, at most half a year, half a year later, we will definitely complete the test launch of the DF-1 that can be used in actual combat!" Qian Xuesen also understood the inside story; he could see many reports and knew very well the situation he was facing now.

Under such circumstances, don't steam buns, fight for a breath; what if there are no Soviet Russia experts? What if you hide a hand? We can still build missiles better than P-1.

He interrupted: "But I always feel that Professor Lin also gave us some other surprises.

Only after Xiao Zhang brings my notebook back can I be sure what the surprise is.

However, I have a vague premonition that after substituting my data into this formula, I can get the result I want."

Qian Xuesen had already walked to the blackboard, and a total of 12 blackboards in front of him occupied an entire wall in a four-by-three manner.

Pull the blackboard up and down through the track pulley to move the content he wants to see to the bottom.

Swish, swish, the sound of the pulley rubbing against the track was exceptionally clear in the Science and Technology Commission office building in the middle of the night, but everyone present didn't feel the sound was harsh, but hoped that Qian Xuesen could really discover something from these dense formulas.

"President, I brought it!" Zhang Kewen arrived at the Science and Technology Commission building panting, not daring to delay for a minute, the whole process was car-picked and car-dropped, and he also ran all the way.

Qian Xuesen rushed up and took the notebook from Zhang Kewen's hand, flipped through it rapidly, and found the page he wanted.

Then Qian Xuesen stood in front of a blackboard that had just been moved to the bottom by him, staring at the blackboard, frowning tightly, his hands calculating frantically in the notebook:

"That's right, it's this!

Sure enough, as I expected, this set of linear equations by Professor Lin really contains this layer of information!" ===== CHAPTER 37 =====
