my scientific age

Chapter 239 Blu-ray!

This is the first official contact between Zhao Zhongyao and Yu Hua. To be honest, he can't imagine the rigorous and demanding behavior of a large number of mathematical calculations through mental arithmetic.

No need for manuscript paper, no need for a pen, mathematical operations through pure thinking, is this something that can be done by human beings?
You must know that this calculation is not the four operations of addition, subtraction, multiplication and division, but the calculation of astronomical data through differential equations and integral equations.

The entire calculation process must be rigorous and accurate, and no errors are allowed.

Whether it is a calculation formula or a result parameter, any errors will lead to errors in the final data.

Zhao Zhongyao's main focus is nuclear physics research, and his mathematical thinking and computing ability are barely able to handle, and he does not possess the extremely terrifying mental arithmetic ability of Yu Hua.

Darling, is this the ability of a top student in the Department of Mathematics?

"Yusheng, you can calculate this parameter." Looking at Yu Hua, who was modest and polite, Zhao Zhongyao suddenly realized something, took a deep breath, calmed down, and then wiped off the title on the blackboard with a board brush, and then wrote a letter with chalk. Set of physical parameters and mathematical formulas, there is a trace of anticipation in his eyes.

There are no questions on the blackboard, only a set of parameters about atoms and electrons, including mathematical formulas, there is no review questions, just calculations.

The only problem is that it is very computationally intensive.

Facing Professor Zhao Zhongyao's test, Yu Hua's face was natural and he was not panicking. He stared at the parameters and mathematical formulas on the blackboard. After obtaining enough data, the thinking computer in his mind entered the operating mode.

In an instant, the whole personality changed again, revealing a sense of absolute rationality.

When using the thinking computer, all of Yu Hua's emotions and human nature will temporarily disappear, and his spirit and attention will be highly concentrated, providing the best environment for the operation of the thinking computer.

The higher the computing speed, the more Yu Hua looks like a real machine.

For this, Yu Hua does not feel that there is anything wrong.

The sets of data in his mind kept beating and changing. Yu Hua's academic level and knowledge reserve were comparable to that of a mathematician, so that he had no obstacles in the entire calculation process. Although he did not understand the meaning and nature of these parameters, there was no problem in the calculation. ,

Quick, quick.

"Sir, this is the final result. Do you need to write down the detailed calculation steps?" After 5 minutes, Yu Hua completed the entire calculation process, picked up the chalk with his right hand and gave the data, and asked Zhao Zhongyao.

"No, if I hadn't seen it with my own eyes, I really couldn't believe that people's mental arithmetic ability could reach this level."

Zhao Zhongyao shook his head gently, and his words were full of surprise and emotion. Even though he was already prepared, he was still shocked by Yu Hua's mental arithmetic ability.

Shocked.

Shock deep inside.

"Sir, you are overrated." Yu Hua said modestly.

"Yu Sheng, are you interested in being my assistant?" Zhao Zhongyao took a deep breath, looked at Yu Hua in front of him, and did not hesitate to issue a formal invitation from the school professor. After the second calculation test, he was keenly aware of Yu Hua. The scientific value of mental arithmetic ability.

According to Yu Hua's current performance, it is no exaggeration to say that this is a walking humanoid computer, but Yu Hua can play an extremely important role wherever calculations are required.

Given the data and the corresponding formula, the results can be obtained after a period of time. Yu Hua's mental arithmetic ability is completely the top assistant that countless scientists dream of.

No, it's a dream lover!
In the blink of an eye, Yu Hua became the sweet pastry in Zhao Zhongyao's eyes. This general education elective nuclear physics course has also become a talent market.

As for whether it is normal or not, whether it is reasonable or not...

Zhao Zhongyao said that it was not important. Anyway, he and Yu Hua were the only people in the classroom.

As an assistant?

Yu Hua, who unexpectedly received the second offer in his life, was stunned for a moment, and immediately understood what Professor Zhao Zhongyao meant, because he saw his computing ability.

Indeed, for a nuclear physicist at the level of Zhao Zhongyao, his top-level mathematical computing ability is of great value, and it can help the other party to calculate and process data, eliminating the tedious and laborious links in the middle.

In fact, not only nuclear physicists, but all scientific research activities require a lot of mathematical calculations.

Yu Hua can understand Professor Zhao's needs, and this formal invitation also proves his worth, but...

Do you need this offer?

The whole person frowned and fell into contemplation.

Looking at the problem from a student's perspective, as a freshman, getting the recognition and formal invitation of the school's professor can already be called an explosion. You must know that the position of a professor's assistant is often at the core level, and someone who is not the professor's most trusted assistant cannot be appointed as an assistant.

As long as there is no accident, Yu Hua works with Zhao Zhongyao, and when he graduates, he can stay in Tsinghua to teach.

In addition, you can also get the moon first, and read Zhao Zhongyao's master's degree, killing two birds with one stone.

The future is bright.

However, Yu Hua is not an ordinary freshman. Oxygen blowing furnace and electroslag remelting technology are still waiting for him to conquer. The prime number theorem and Goldbach's conjecture in mathematics have to be dealt with, "Introduction to Military and Civilian Guidance" It's not finished yet, and there's almost no free time.

Most importantly, he is going to study in the United States.

"Professor, thanks to your kindness, the students are very grateful, but the students are going to apply for the Geng-funded public-funded students to study in the United States. Even if they agree to be your assistants, the students will not be able to stay for long." Yu Hua weighed it and thought about it. Without shaking his head, he chose to decline the formal invitation from Zhao Zhongyao.

"I see……"

When Zhao Zhongyao heard this, he was a little disappointed. He thought about it in his heart, looked at Yu Hua, and asked, "Yu Sheng, which school are you going to study in the United States?"

"Probably first go to Princeton to study for a master's degree and a doctorate in mathematics, and then go to Caltech to study for a doctorate in nuclear physics and a doctorate in aviation." Yu Hua heard the words, but he did not hide his future plans, and told the truth.

First to Princeton, then to Caltech, the main planned route to study abroad.

Mathematically determines the upper limit,

Nuclear physics determines the future,
Aeronautics is now.

The world after World War II and World War II is entirely centered on the fight for air supremacy. To fight for air supremacy, it is inseparable from fighter jets with excellent performance and advanced performance.

These are the three main research directions planned by Yu Hua.

Hearing Yu Hua's answer, a smile appeared on Zhao Zhongyao's face, and he betrayed him: "Yu Hua, do you know who my teacher is?"

"Your teacher is Robert Andrew Millikan, Nobel Prize winner in physics." Yu Hua said with some doubts in his heart.

"Then do you know who is the current chairman of the executive committee of Caltech?" Zhao Zhongyao continued to ask.

Yu Hua shook his head: "Students don't know."

The chairman of the executive committee of the California Institute of Technology is equivalent to the position of the president of National Tsinghua University. The specific candidate Yu Hua is not clear.

"The current chairman of Caltech's executive committee is my teacher, Millikan." Zhao Zhongyao said with a smile.

Yu Hua's face is full of confusion: "???"

What the hell, the world is so small? !
Yu Hua never imagined that, through Professor Zhao Zhongyao, he would inadvertently be involved in the seemingly distant California Institute of Technology on the other side of the ocean.

"For the rest of my life, being my assistant does not conflict with studying in the United States. It can even be said that they complement each other. First, you can participate in scientific research experiments and gain rich experience. Second, you can increase your resume and be more competitive than your peers."

Zhao Zhongyao smiled and said: "If you want, I will write you a letter of recommendation before you go to study in the United States. You can take my letter of recommendation and go to my teacher Millikan at any time, I believe he will give you a letter of recommendation. You have a good answer."

Letter of recommendation from professor.

The classroom was quiet, and Yu Hua fell into silence when these words came into his ears. He, who was originally determined, was still shaken by the letter of recommendation promised by Zhao Zhongyao.

Marxist-Lenin is above, not because he is not firm, but because Professor Zhao Zhongyao has given too much.

There are really too many.

It is a matter of course for Yu Hua to enter the California Institute of Technology in the future, and he will not be disturbed by influences other than academics.

In terms of Yu Hua's ability, it is no problem to enter the California Institute of Technology, but he is afraid of other influences. It must be clear that the California Institute of Technology belongs to the top of the pyramid of the American university system. The threshold is not only ridiculously high, but also Others are highly regulated.

The Centennial Exclusion of China is no joke.

The spine of this professor's recommendation letter completely hit Yu Hua's weakness.

"Sir is so kind, the students don't dare to make excuses." Yu Hua sighed in his heart, given too much, his soul forced himself to sell his body, bowed his whole body, accepted the offer from Zhao Zhongyao, and officially became a migrant worker.

"This is the key to the nuclear physics laboratory. Next, you need to familiarize yourself with the laboratory and work. All you have to do is to help me calculate the data. I am usually too busy by myself."

Zhao Zhongyao showed a comfortable smile on his face, then took out the key of the nuclear physics laboratory, handed it to Yu Hua, and arranged to instruct: "The laboratory has a place to live, if you want, you can move here, it's more convenient, every month Eight yuan subsidy, you can ask me if you don’t understand anything.”

"Students know, that, professor, what about my general education elective course." Yu Hua took the key of the nuclear physics laboratory, responded respectfully, and then asked.

"You study while experimenting in the laboratory, combining practice and theory, and you will be given 10 credits from the final exam."

Zhao Zhongyao waved his hand very generously, suddenly thought of something, and said with concern: "Yu Sheng, are you going to take the exam for this year's Geng-funded student studying in the United States, or next year?"

"Students are going to take the exam this year." Yu Hua was silent and responded.

"This year? Then you have to work hard to prepare for the exam. If nothing else happens, the exam for public-funded students studying in the United States will be held in mid-August this year. At that time, you will go to Nanjing to take the exam." Zhao Zhongyao nodded and reminded.

Unfortunately, there will be surprises this year.

Yu Hua nodded in response, but did not inform Zhao Zhongyao of the impending full-scale war of resistance. Historically, due to the influence of the full-scale war of resistance, Pingjin fell and North China was lost. The three schools of Qingbei and Nankai were evacuated from Pingjin, and Changsha Temporary University was built in Changsha, which is the predecessor of Southwest Associated University.

The public-funded exam for students studying in the United States with only [-] places will definitely be affected by this catastrophe, and it has to be postponed.

Yu Hua does not know exactly when it will be held.

However, he must take the exam for students studying in the United States under the Geng-funded funds. If he does not participate, he will not be able to study in the United States, and will lose the opportunity to make a fuss during the window period before the outbreak of World War II.

China had a window period before the outbreak of the Anti-Japanese War, and the whole world had a window period before the outbreak of World War II.

In Yu Hua's view, as a traveler, we must not waste this opportunity to make a fuss.

Waste is the same as failure. ——This is the basic quality that a qualified transmigrator should have.

"Yusheng, let's go to the laboratory and show you the true charm of nuclear physics." At this time, Zhao Zhongyao suddenly said before he finished class.

Yu Hua was full of curiosity and nodded, just as there was no class in the afternoon, he followed Zhao Zhongyao out of the classroom and went to Tsinghua Garden and even the most mysterious laboratory in China.

Zhao Zhongyao and Yu Hua passed through the Machinery Hall and the Chemistry Hall, and came to a not-so-big two-story red brick building with a plaque on the door that read: Nuclear Physics Laboratory of National Tsing Hua University.

Standing in front of the door, Zhao Zhongyao motioned for Yu Hua to come forward.

Yu Hua nodded, stepped forward with the key, unlocked the door, and pushed open the closed door of the laboratory building. The various cutting-edge equipment and instruments that existed in the imagination did not exist. The first floor of the laboratory building looked nothing like the teaching building. the difference.

"Follow me." Zhao Zhongyao said to Yu Hua, and stepped into the laboratory building first and went straight inside.

Yu Hua followed in the footsteps, and the two walked along the corridor. Soon after, they came to a closed door with the information of Laboratory No. [-] written on the door.

Zhao Zhongyao took out a key from his body, unlocked it, and pushed in the door.

Yu Hua followed behind, and walked into the laboratory with curiosity.

"It's an optical microscope."

"This is the Wilson Cloud Chamber, one of the main research instruments in nuclear physics. It is said that the California Institute of Technology has used the improved Wilson Cloud Chamber, and the improver is Mr. Millikan."

"This is an ionization chamber, and it's one of the main research equipment. It's very valuable. I brought it back from Caltech."

In the laboratory, the light is dim, the windows are all covered with black curtains, and all kinds of experimental equipment and utensils are all around. There is an optical microscope at the front, and the famous Wilson cloud room is next to it. Professor Zhao Zhongyao introduced to Yu Hua like a treasure. experiment apparatus.

Yu Hua, like Grandma Liu entering the Grand View Garden, looked curiously at these extremely primitive and rudimentary equipment. It was hard to believe that human physicists discovered and studied nuclear physics through such experimental instruments, mastered the planetary structure of atomic nuclei, and discovered radioactivity. and rays.

Magic.

Really amazing.

At this time, Professor Zhao Zhongyao suddenly made a gesture to signal Yu Hua to follow. Then, he walked towards the innermost part of the laboratory, came to a cabinet, crouched down, opened the cabinet, and carefully took out a wooden box.

Yu Hua stood behind him, his eyes staring at the not-so-big wooden box, the shape of a cuboid, the volume of which was like the flying Maotai box of later generations. Looking at Professor Zhao Zhongyao's solemn appearance, the whole person was somewhat looking forward to it.

Under Yu Hua's gaze, Professor Zhao Zhongyao opened the lid of the wooden box, and in an instant, a faint blue light appeared.

Blu-ray!

A very pure and high-energy blue light.

A glass bottle containing 50 mg of radium was taken out by Professor Zhao Zhongyao and placed on the surface of the experimental bench.

This is the only [-] mg of radium in China, and it is also the most important nuclear physics experimental research material in China.
