Chapter 98 Thinking Finite Element Analysis System!
Yu Hua showed a serious face.

"It's very impolite to ask a girl such a question in person." Lin Wan was startled for a moment, her face turned slightly red, and she gave Yu Hua a white look. It was the first time she had seen such a blatant question.

"Hey, it's just a joke." Yu Hua smiled, and quickly covered up his embarrassment. Well, he has to admit that he just twitched his head, and under the influence of primitive instinct, he reversed the mistake that a man should make.

joke?

Lin Wan was slightly helpless. She could accept Yu Hua's joke. Seeing Yu Hua, she seemed a little embarrassed. A slight smile appeared on her white face, reminding her:
"Graduation is coming, learn and cherish it, don't pay attention to the affairs of your children."

"Hua has been taught." When Yu Hua heard this, he naturally understood the meaning and nodded.

Seeing Yu Hua's calm attitude, Lin Wan smiled: "You can just call me Jin Yu in the future. This is my character, did you take it?"

"No." Yu Hua was slightly surprised. He didn't expect that Lin Wan still had a list of words, so he wrote down the word Jin Yu in his heart.

Table characters, which played an important role in ancient history, were treated as feudal dross and suffered a devastating blow after the New Culture Movement.

"Chinese culture is broad and profound, with dross and essence. The words should not be swept into the garbage heap of history. This is also my original intention of choosing the words. You can take one and read the book." Seeing the surprise on Yu Hua's face Lin Wan explained her expression in a soft voice, and when the words fell, she turned her head, revealing her fair face, and stretched out her hand to tuck a few strands of black hair behind her ears, concentrating on her studies.

"Character..."

Yu Hua retracted his gaze, thoughtfully, and felt that Lin Wan was right. After thinking about it, he couldn't think of a suitable word for him for the time being. He shook his head slightly, and turned his attention to his studies.

Opened the calculus content of "Theory of Calculus", Yu Hua read it carefully, and constantly absorbed the basic knowledge and important content about calculus. As more and more knowledge was absorbed, Yu Hua's knowledge level and details became more and more. the deeper.

But this is not enough.

There is so much difference between rote memorization and mastery.

After reading all the contents of the Bernhard Riemann Integral, Yu Hua raised his head, closed his eyes, and began to recall the book knowledge he had just read. His brain, like a high-performance computer, entered a state of full-load operation, extracting one-sided pieces from the depths of his memory. And abstract mathematical formulas rich in logic, listed separately.

Quietly staring at these mathematical formulas suspended in mid-air, Yu Hua began a journey of integration and integration. His brain extracted the image of memory and conception. In a flash, an image of a stable shelling armor-piercing projectile with a tail moving at a high speed of 1500 meters per second appeared. All he had to do was Calculate the surface area, rotating surface area, kinetic energy change and kinetic energy attenuation value of the projectile during flight, and obtain the tilting force values ​​at 500 meters, 1000 meters and 2000 meters according to the velocity function and kinetic energy formula.

detail!

Yu Hua carefully thought about every detail of this piece, from its size, volume and initial velocity, and other physical quantities, to be as detailed as possible, so as to meet the real environment and achieve the maximum tempering effect.

This is Yu Hua's exclusive learning ability.

With a brain with strong computing power, Yu Hua can build a realistic approximate physical system with a state of mind. The whole system can highly simulate various situations, and Yu Hua can perform efficient and repetitive training in this approximate physical system.

The last time Yu Hua was able to quickly master electric welding technology was the result of hundreds of times of training in his brain.

This operation sounds incredible, but in fact, even Yu Hua feels incredible.

After Yu Hua discovered this ability, he faintly felt that his brain didn't seem to stop evolving, but was subtly enhanced without his knowledge, moving towards an unknown height.

This is a situation that cannot be explained by science. In other words, Yu Hua cannot use the scientific language he has mastered at this stage to describe his own situation.

He only knew that a constantly growing brain was a good thing for him.

In his mind, the parameters of the entire detachment and piercing shell were continuously simulated and given. Yu Hua calculated the physical parameters obtained by the measurement using the integral formula he learned today.

In the initial stage, due to the complex integral formula and the difficulty in maintaining the entire thinking similar to the physical system, Yu Hua's calculation and deduction process was particularly difficult, the available brain computing resources were few, and the calculation progress was very slow.

After 5 minutes, the surface area, rotational surface area, rotational inertia and other parameters of this tail-stabilized AP shell were quietly suspended next to the high-speed stripping shell.

The left is the mathematical formula, the middle is the piercing shell, and the right is the calculation result.

"The parameters are correct. Continue to deduce. The first integral calculation exercise took 5 minutes, which is too long. It must be reduced to less than 30 seconds." Establishing a thinking-like physical system to complete an integral calculation exercise, Yu Hua checked the calculation results for the second time and confirmed Correct, silently pondering.

correct.

All physical parameters of the whole shell are correct, and the integral calculation practice process is rigorous and meticulous, and there is no error.

However, Yu Hua was still not satisfied.

5 minutes is too long.

As a man who is about to embark on the road to the Temple of Science as a scholar, Yu Hua has extremely high demands on himself.

For simple calculus questions, the calculation process should not exceed five seconds, and the calculation process must be kept within 30 seconds while maintaining the state of thinking similar to the physical system.

In this way, it is possible to cope with the countless computing needs of future scientific research careers.

This is a requirement for self and also for intelligence.

The mind changes, the brain extracts the memory again, and the thinking approximates the physical system to present another realistic image. A Zero fighter jet with black smoke on its wings and crashing to the sea appears. Find the current surface area and volume of the entire fighter jet, as well as its own movement. Variety.

Integral calculation practice, start again.

Yu Hua was immersed in it, and began to practice point calculation again and again.

5 minutes.

Four minutes and 30 seconds.

4 minutes.

Three minutes and 55 seconds.

The proficiency progress of integral calculation practice has become a non-linear increase trend. There is no time in learning, and time passes slowly. After a calculation practice, Yu Hua has a very high degree of mastery of mathematical formulas.

By the time of class in the afternoon, Yu Hua, who had completed more than [-] times of integral calculation exercises, had mastered the important basic content and knowledge points of integral science, from rote memorization to the level of integration. Yu Hua can solve the mathematical problem of indefinite integral with just a glance.

Of course, doing math problems is not the purpose of Yu Hua's study of calculus.

Mastering calculus thoroughly and making it a mathematical weapon in his own hands is what motivates Yu Hua to learn calculus.

"I have basically mastered the one-dimensional integral and the double integral now, and there will be the integral and numerical integral of Lebesgue next. According to the current efficiency, I can fully grasp the calculus and differential calculus in about ten days, 20 I will thoroughly learn calculus within a day, but it should be noted that it is important to lay a solid foundation and details, and after mastering calculus, I can further improve my thinking to approximate physical systems.”

Yu Hua finished today's integral calculation exercise, thinking quietly, his eyes flickering: "The establishment of a thinking finite element analysis system is just around the corner."

With this brain comparable to a computer, Yu Hua has no doubt that after he has learned calculus and mathematical analysis, he will not be able to accomplish his goals.

Thinking finite element analysis system!
This is Yu Hua's idea that was inspired by the thinking similar to the physical system before, and it has never been revealed in the true sense. It was not until last night when he was apprenticed to Hua Luogeng that Yu Hua's goal became clear.

The importance and practical application of finite element analysis is self-evident. Yu Hua can use finite element analysis in any applied scientific research or engineering project in the future.

But limited by the computer, in 1937, it was almost impossible to use a finite element analysis system.

Fortunately, his brain, which has been continuously strengthening, gave him the dawn of using a finite element analysis system, that is, with the computing power provided by the brain, he abruptly established a thinking finite element similar to a biological computer. analysis system.

No CPU?

It doesn't matter, I have a brain.

No graphics card?

It doesn't matter, I have a brain.

No calculus and mathematical analysis?

Very important!
Without knowledge, no matter how strong Yu Hua's brain is, it is useless.

After thinking about the goal of his own abilities, Yu Hua suddenly felt a sense of dizziness, followed by a bulging pain in his temples.

Yu Hua was very familiar with this feeling.

Feeling his own situation, Yu Hua sighed: "Unfortunately, it's good to think like a physical system, but I can't hold on to my energy. It's only been about 2 hours, and I've reached the limit of 8 hours of study per day. Once the thinking finite element analysis system is established, I can start to realize the things in the plan. I have been busy with my studies recently, and I haven’t written the three sacred books yet, but the drawing standards are almost the same.”

Thinking about it, at this time, the pain in the temples on both sides became stronger and stronger, Yu Hua didn't dare to think any more, and let him rest.

It's time to rest.

Just wait in the classroom and look at the high school questions and relax.

After resting for about 10 minutes, the swelling and pain in the temples gradually subsided, and the feeling of near fainting disappeared. It was almost time, and the desk next to him was empty, and the beautiful woman disappeared. Yu Hua packed up four treasures that were extremely important to him, and went to the classroom .

For Hua Luogeng, the symbolic meaning of the four high-number books is greater than the actual meaning.

But to Yu Hua, these four advanced mathematics textbooks are more important than a golden mountain.

Knowledge, the crystallization of the wisdom of human civilization.

The importance of knowledge has been throughout the development of human civilization since ancient times.

……

Tsinghua West Courtyard, Room 28, Study.

Hua Luogeng sat on the main seat, holding a draft paper in his right hand, a cup of hot tea next to him, a slowly burning cigarette in his left hand, his face slightly solemn, and his eyes staring at the large number of confidential documents stacked on the surface of the table.

On the topmost layer is a confidential document with the seal of the Secret Service Office of the Fuxing Society on its surface, with a line of words on it, Japanese diplomatic cipher text.

"Replacement codes and language codes are used, and the encryption mechanism is complicated. Let's not talk about it, but the problem is the language. It seems that this is not the official language of Japan, but a dialect of Japanese." Hua Luogeng finished studying the pile of Japanese recipes that Zhang Zizhong personally sent in front of him. Diplomatic cipher text, frowning slightly, making trouble.

PS: I have been sluggish for a day and a night, and the whole person is almost collapsed. I am sorry, the situation is a little better today. I will wait and see if I can come again. I will update a lot tomorrow.
