Chapter 95 Thinking Finite Element Analysis System!
Yu Hua showed a serious face.
"Asking such a question to a girl face to face is a very impolite behavior." Lin Wan was stunned for a moment, her face turned slightly red, and she rolled her eyes at Yu Hua. This was the first time she had seen such a naked question.
"Hehe, it's just a joke." Yu Hua chuckled and quickly covered up his embarrassment. Well, he had to admit that his brain had a twitch just now and he made a mistake that every man should make under the influence of primitive instinct.
joke?
Lin Wan was slightly helpless. She was the only one who could accept Yu Hua's joke. Seeing that Yu Hua seemed a little embarrassed, a faint smile appeared on his face as white as cream, and she reminded:
"Graduation is coming soon, learn and cherish it, and don't pay attention to your children's affairs."
"Hua has learned a lesson." After hearing this, Yu Hua naturally understood the meaning and nodded.
Lin Wan saw Yu Hua's calm posture and smiled: "From now on, you can just call me Jin Yu. This is my name. Have you chosen the name?"
"No." Yu Hua was slightly surprised. He didn't expect Lin Wan to have a pseudonym, so he wrote down the word "Jin Yu" in his mind.
Biaozi, which played an important role in ancient history, was regarded as feudal dross after the New Culture Movement and suffered a devastating blow. Since the end of the New Culture Movement, literati and poets rarely used Chinese characters.
"Chinese culture is vast and profound. It has its dross and its essence. People should not sweep the word "Biao" into the garbage dump of history. This is also my original intention of choosing the word "Biao". You can pick one and read." Seeing the surprise on Yu Hua's face.
Expression, Lin Wan explained softly. After finishing her words, she turned her head, revealing her fair face. She reached out to tuck some scattered black hair behind her ears and concentrated on studying.
"Character..."
Yu Hua withdrew his gaze, thoughtfully, and felt that Lin Wan was right. After thinking about it, he couldn't think of any words that suited him for the time being. He shook his head slightly and turned his attention to his studies.
Turning over the integral calculus content of "The Theory of Calculus", Yu Hua read it calmly, constantly absorbing the basic knowledge and important content about integral calculus. As he absorbed more and more knowledge, the level of knowledge and details Yu Hua mastered also increased.
Go deeper.
But, this is not enough.
There is a huge difference between rote memorization and mastery.
After reading the entire content of Bornhard Riemann Integral, Yu Hua raised his head, closed his eyes, and began to recall the knowledge in the book he had just read. His brain, like a high-performance computer, entered a state of full load operation, extracting bits and pieces from the depths of his memory.
And abstract mathematical formulas rich in logic are listed separately.
Quietly watching these mathematical formulas suspended in mid-air, Yu Hua began the journey of integration, and his brain extracted memories to conceive images. In an instant, an image of a tail-stabilized armor-piercing projectile moving at a high speed of 1,500 meters per second appeared. What he had to do was
Calculate the surface area, rotation surface area, kinetic energy change and kinetic energy attenuation value of the projectile during flight, and obtain the pouring force values of 500 meters, 1000 meters and 2000 meters based on the speed function and kinetic energy formula.
detail!
Yu Hua carefully conceived every detail of this detachment, 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 greatest degree of tempering effect.
This is Yu Hua’s exclusive learning ability.
Relying on a brain with extremely powerful computing power, Yu Hua is able to construct a realistic approximate physical system in a state of mind. The entire system can highly simulate various situations. Yu Hua can conduct efficient and repetitive training in this approximate physical system.
The last time he was able to quickly master the welding technique was the result of Yu Hua training it in his brain hundreds of times.
This operation sounds incredible. In fact, even Yu Hua found it incredible.
After Yu Hua discovered this ability, he vaguely felt that his brain did not seem to have stopped evolving. Instead, it was subtly strengthening without his knowledge, rising towards an unknown height.
This is a situation that cannot be explained scientifically, or in other words, Yu Hua cannot use the scientific language he masters at this stage to describe his own situation.
He only knows that his increasingly stronger brain is a good thing for him.
In his mind, various parameters of the entire detonation shell were continuously simulated. Yu Hua used the integral formula learned today to calculate based on the measured physical parameters.
In the initial stage, due to the complexity of the integral formula and the difficulty of maintaining the entire mental approximation of the physical system, Yu Hua's calculation and deduction process was particularly difficult. There were very few brain computing resources available and the calculation progress was very slow.
Five minutes later, the surface area, rotation surface area, rotational inertia and other parameters of this fin-stabilized armor-piercing shelling projectile were quietly suspended next to the high-speed traveling shell.
The left side is the mathematical formula, the middle is the detonation shell, and the right side is the calculation result.
"The parameters are correct, let's continue the deduction. The first integral calculation exercise took five minutes. It was too long and must be reduced to less than thirty seconds." A thinking approximate physical system was established to complete an integral calculation exercise. Yu Hua checked the calculation results a second time.
Confirm it is correct and think silently.
correct.
All the physical parameters of the entire detonation shell are correct, and the integral calculation practice process is rigorous and meticulous, with no errors.
However, Yu Hua was still not satisfied.
Five minutes is too long.
As a man who is about to embark on the road to the temple of science as a top student, Yu Hua has extremely high requirements for himself.
For simple calculus questions, the calculation process should not exceed five seconds. While maintaining the approximate physical system of thinking, the calculation process must be kept within thirty seconds.
In this way, we can meet the countless computing needs in our scientific research career in the future.
This is a requirement for self and also a requirement for IQ.
The mind changes, the brain extracts the memory again, and the thinking approximates the physical system to present another immersive image. A Zero fighter jet with black smoke falling from its wings to the sea appears. Find the current surface area and volume of the entire fighter jet, as well as its own motion.
change.
The integral calculation exercise begins again.
Yu Hua was immersed in it and began to practice integral calculation again and again.
Five minutes.
Four minutes and thirty seconds.
Four minutes.
Three minutes and fifty-five seconds.
The progress of proficiency in the integral calculation practice has a non-linear increasing trend. There is no time to learn, and time passes slowly. After a calculation practice, Yu Hua has an extremely high degree of mastery of mathematical formulas.
By the afternoon class, Yu Hua, who had completed more than 30 integral calculation exercises, had mastered the important basic contents and knowledge points of integral calculus from rote memorization to a comprehensive level. Now, he can calculate the definite integral sum casually.
Yu Hua could solve the mathematical problem of indefinite integrals just by looking at it.
Of course, doing math problems was not Yu Hua’s purpose in learning calculus.
Completely mastering calculus and turning it into a mathematical weapon in his own hands was Yu Hua's motivation for learning calculus.
"Now I have basically mastered the one-variable integral and the double integral, and then there will be the integral and numerical integral of Mr. Lebesgue. According to the current efficiency, I will be able to fully master the integral calculus and differential calculus in about ten days.
Learn calculus thoroughly in ten days, but it should be noted that it is important to solidify the basics and details. After mastering calculus, you can further improve your thinking to approximate the physical system."
Yu Hua finished today's integral calculation exercise and thought quietly, his eyes flashing: "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 learns calculus and mathematical analysis, he will not be able to achieve his goals.
Thinking finite element analysis system!
This is an idea that Yu Hua came up with when he was inspired by the approximate physical system of thinking. It has never been revealed in a real sense. It was not until he became a disciple of Hua Luogeng last night that Yu Hua's goal became clear.
The importance and practical applications of finite element analysis are self-evident. Yu Hua will be able to use finite element analysis whenever he is involved in any applied scientific research or engineering projects in the future.
However, due to computer limitations, it was almost impossible to use finite element analysis systems in 1937.
Fortunately, his brain, which has been constantly improving, gave him the dawn of the use of finite element analysis systems. That is to use the computing power provided by his brain to abruptly build 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 or mathematical analysis?
Very important!
Without knowledge, no matter how strong Yu Hua's brain is, it will be useless.
After thinking about the goals of his abilities, Yu Hua suddenly felt waves of dizziness, and then he felt a bulging pain in his temples.
Yu Hua was very familiar with this feeling.
Feeling his own situation, Yu Hua sighed: "Unfortunately, my energy cannot support it. It has only been about 2 hours, and I have already reached the limit of 8 hours of learning per day.
Once I establish the thinking finite element analysis system, I can start to realize the planned things. I have been busy with my studies recently and haven’t written the three sacred books yet, but the drawing standards are almost there.”
As he thought about it, the swelling and pain in his temples on both sides became stronger and stronger. Yu Hua did not dare to think any more and let his brain rest.
It's time to rest.
Go to the classroom and read high school questions to relax.
After resting for about ten minutes, the swelling and pain in his temples slowly subsided, and the feeling of almost fainting disappeared. It was almost time, the desk beside him was empty, and the beauty was nowhere to be seen. Yu Hua packed up four treasures that were extremely important to him and went to the classroom.
.
For Hua Luogeng, the symbolic significance of the four advanced mathematics books is greater than the practical significance.
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 existed throughout the development of human civilization from ancient times to the present.

Tsinghua University West Campus, Room 28, Study.
Hua Luogeng sat on the main seat, holding a draft paper in his right hand, with a cup of hot tea beside him, and a slowly burning cigarette in his left hand. His face was slightly solemn, and his eyes were staring at the large number of confidential documents piled on the surface of the desk.
The topmost document was a confidential document stamped by the Secret Service of the Fuxing Society, with a line of Japanese diplomatic secrets written on it.
"Replacement codes and language codes are used. Let's not talk about the complexity of the encryption mechanism for now, but the problem lies in the language. This does not seem to be the official language of Japan, but a general Japanese language." Hua Luogeng finished studying the pile of Japanese documents sent by Zhang Zizhong himself.
PS: I had diarrhea all day and night and almost collapsed. Sorry, my condition is a little better today. I will wait and see if I can come again. I will update a lot tomorrow.
