Chapter 215 General knowledge of nuclear physics!

The words are full of respect, and the whole person's posture is even more respectful, well-behaved, without the slightest publicity.

Facing this top nuclear physicist, Yu Hua respected him from the bottom of his heart.

How awesome is Professor Zhao Zhongyao?
The first scientist to discover antimatter in human history provides a theoretical basis for the development of a positron-positron collider. His academic achievements can easily join the top nuclear physicists club, and his contribution to physics is no less than that of Marie Curie. Scientists of this level.

While others were racking their brains and still conceiving their graduation thesis, Zhao Zhongyao, who was only 28 years old under the tutelage of Nobel laureate Robert Millikan, had already become an acquaintance of top academic journals such as "Nature" and "Physics Letters".

If the above is not enough to show that Professor Zhao Zhongyao is awesome, then you can take a look at the students of the boss.

Deng Jiaxian, Qian Sanqiang, Zhou Guangya, Wang Ganchang, Yang Zhenning, Li Zhengdao... These are all students of Professor Zhao.

Among the 23 bigwigs involved in the two bombs and one satellite project, nine are students of Professor Zhao.

He is a top figure in the international physics community and a leader in the Chinese physics community, and has a pivotal influence in the field of physics.

The establishment and early development of Chinese nuclear physics depended entirely on Zhao Zhongyao's efforts.

In addition, Professor Zhao presided over the construction of the first and second proton electrostatic accelerators in China, which laid a solid foundation for the birth of Miss Qiu.

This is Professor Zhao's awesomeness!
However, Professor Zhao Zhongyao failed to get the honor he deserved. The heavyweight achievement of 'discovering the phenomenon of antimatter' should have won the Nobel Prize, but it was stolen and published by his classmates and missed the Nobel Prize.

Facing such a big blow, Professor Zhao Zhongyao did not lose heart, but cheered up and continued to engage in academic research. Then he returned to China a few years ago with the most cutting-edge and advanced knowledge in the field of physics, and was employed by Tsinghua University. Tsinghua University hosted the first nuclear physics course in China and built the first nuclear physics laboratory in China.

In Zhao Zhongyao's hands, he holds the only 50 mg of radium in the whole of China. Don't look at 50 mg of radium. In fact, this is a real invaluable treasure. the foundation of the nuclear weapons business.

As the first nuclear physicist in Chinese history, Zhao Zhongyao has made indelible contributions to Chinese nuclear weapons and physics. However, his name is rarely known and can even be described as obscurity.

This is the real uncrowned king of physics and the founder of Chinese nuclear physics.

In a sense, Professor Zhao Zhongyao in front of him can be called Yu Hua's future grandfather.

"Hello, Yu Hua, I've heard of you. This year's top student in the joint entrance examination has excellent grades." Zhao Zhongyao was a little surprised and surprised when he heard Yu Hua's self-introduction. The top student said with a smile.

"You are overrated, Professor." Yu Hua said modestly.

Zhao Zhongyao, who was in a hurry, saw Yu Hua being so polite and disciplined. He recalled Dean Ye's previous evaluation of Yu Hua, and he couldn't help but feel a sense of joy, and patiently said: "I heard Dean Ye say that you are in physics. I am very talented, if you are interested, you can take my general nuclear physics course as an elective, after all, mathematics and physics are not separated, and my course has 10 credits."

The Dean Ye in Zhao Zhongyao's mouth was naturally Ye Qisun, Dean of Science.

10 credits, this is the only general elective course of National Tsing Hua University with super high credits.

National Tsing Hua University adopts the credit academic year system derived from Harvard University. It stipulates that students must complete 132 credits in four years, which are divided into departmental curriculum professional education and school general education. The former is 102 credits, and the latter is 30 credits. Only after paying all the prescribed fees and passing the examination can they graduate and be awarded a bachelor's degree.

The general education of the school is divided into 10 points for party morality, 4 points for physical education, 4 points for military training, 2 points for foreign language, and 10 points for general elective courses.

Generally speaking, students need to choose two or three general education elective courses to complete 10 points, and the advantage of general nuclear physics course is that only after completing this course can get ten credits, which greatly saves time.

Of course, the reason why nuclear physics courses are so high credit is because it is too difficult.

"Professor, students need to think about it." Hearing Zhao Zhongyao's words, Yu Hua was a little surprised and pondered for a while, but did not agree immediately.

"It's okay, nuclear physics is an emerging branch of physics with great application potential in the future. If you are interested in nuclear physics, you can come to me at the nuclear physics laboratory at any time. Of course, you can also listen to me. My big class, I still have something to do, go first, classmate Yu." Zhao Zhongyao showed a peaceful smile, not angry, gave a brief introduction to Yu Hua, then said goodbye and left.

"Students understand, professor, walk slowly." Yu Hua said goodbye.

Zhao Zhongyao nodded with a smile, his posture was tall and straight, his steps were steady and fast, and he left quickly with his briefcase in his hand. It could be seen that he was in a hurry.

"Nuclear physics... The theoretical basis and support of nuclear physics is inseparable from nuclear physics. However, it is still too early for me to engage in study and research in the field of nuclear physics. First, my physical level and knowledge reserve Insufficient, secondly, the timing is not right, and thirdly, the environment of the Republic of China is not suitable for nuclear physics research, so we still have to go to the United States.”

Yu Hua looked at Zhao Zhongyao, the founder of Chinese nuclear physics, who was leaving, and said softly to himself, "However, there is no problem with studying nuclear physics as an elective in general education."

In 1896, the physicist Becquerel discovered natural radioactivity, which was the first time that nuclear changes were observed in human history. As a result, a new branch of physics was born - nuclear physics.

As a discipline of physics that was born less than 40 years ago, nuclear physics is currently a hot frontier field of physics. Physicists have realized the terrifying energy contained in the nucleus and are trying to develop and master this power.

Various types of nuclear weapons with huge lethality in later generations, atomic bombs, hydrogen bombs, three-phase bombs, neutron bombs, electromagnetic pulse weapons, depleted uranium bombs and dirty bombs, etc., their theoretical foundations all come from nuclear physics.

The current time node for the development of nuclear physics is Zhao Zhongyao's discovery of the generation and annihilation of positron-electron pairs. Next, an electrostatic particle accelerator will be established to provide a hardware foundation for nuclear research and nuclear technology applications. By December 1938, mankind will be the first The discovery of the existence of nuclear fission has brought nuclear physics research into a period of great development.

To be honest, for this cutting-edge discipline, Yu Hua is not ready for the time being. His academic level and knowledge reserve are far from enough, and the current time is not suitable.

Nuclear physics is the central pillar of the future plan, and it is very important. However, Yu Hua still wants to take advantage of the window period before the outbreak of the full-scale Anti-Japanese War to provide the base areas with engineering technology applied in the military and industrial fields.

However, it is not a problem to choose nuclear physics as a general elective course to lay the foundation. After all, this is studying with Professor Zhao Zhongyao.

Professor Zhao Zhongyao is not only a top physicist, but also a Chinese scientist who was the first in history to realize the horrors of atomic weapons.

It was such a happy decision that the general elective course was reported to nuclear physics.

I ran into Professor Zhao Zhongyao and revised the current plan. Yu Hua smiled slightly, walked back with a small box, left the Tsinghua Academy, walked through the campus, and returned to the West Campus.

Now, Yu Hua's return to the West Court is like coming home, natural and familiar.

When Yu Hua entered the door, there was a busy voice in the kitchen. He walked through the hallway and came to the kitchen entrance. He saw his wife Wu Xiaoyuan wearing an apron and cutting vegetables on the stove.

"Master." Yu Hua respectfully said.

"Come back? Luo Geng is still in class, let me cook earlier today and said you are coming."

When Wu Xiaoyuan heard the shout, he turned to see Yu Hua, with a kind and gentle smile on his face, and said softly, "Your master may not be back for half an hour, wait for him to come back for dinner."

"Students have been dealing with trivial matters at home these past few days. I received the notice today and will report to the school immediately. Teacher, please come over here, the students have something to do." Yu Hua nodded and said.

"What's the matter? Xiaohua."

Hearing this, Wu Xiaoyuan was a little puzzled, put down the kitchen knife in his hand, and came towards Yu Hua.

Yu Hua carried the small box to the main room, and his wife Wu Xiaoyuan followed closely. Immediately, he put the small box on the table top, opened the lid, and revealed the ocean wrapped in red cloth.

"Xiaohua, where did you get this money from?" Wu Xiaoyuan was startled when he saw the big ocean and red cloth in the small box, and looked at Yu Hua, a little confused.

This was the first time she had seen so many oceans.

"The student-to-student scholarship is 490 yuan per year. This is the share of the first academic year. The total is [-] yuan. The student has previously paid [-] yuan in advance. Teacher, the student will keep this money for a rainy day. The rest of the amount will be handed over to you to subsidize the family expenses." Yu Hua looked serious and solemn, with his back straight, bowed to Wu Xiaoyuan and gave the reason and arrangement for this box of silver dollars.

When Wu Xiaoyuan heard Yu Hua's words, he was stunned for a moment, and quickly said, "How can this be made? No, Xiaohua, it is absolutely impossible!"

She couldn't believe what she heard. Most of the ocean in this box was used to subsidize the family, and only a hundred oceans were left for emergencies.

This is a whole ocean of 390 yuan!

"Teacher, listen to what the students have to say. Master treats me like a mountain. He teaches students knowledge, and enlightens students with wisdom. Students have grown up from a poor school to today without Master's diligent teaching. In addition, you are also working hard day and night. Laundry and cooking are inseparable, treat students like parents and children, treat students as if they are their own, and be reasonable. Students have some meager scholarships, and of course they have to subsidize their families. Otherwise, what is the difference between Zhongshan Lang?"

Yu Hua bowed slightly, showing respect as a student, and his eyes were full of respect: "Besides, Master has three older brothers and a younger sister to take care of, and there are elders in the family, money is used everywhere in life, and the situation in Peiping is getting worse and worse. In the event of a crisis, the Japanese invaders may soon invade the Chinese rivers and mountains again. At that time, life will be ruined. Whether they stay in Tsinghua Garden or leave Peiping, they cannot do without money. The French currency is depreciating greatly, only the silver dollar is still strong. "

"Master, this is a part of the student's heart, and I hope you will accept it."

Historically, with the outbreak of the full-scale Anti-Japanese War and the rapid rise in prices, professors from Tsinghua University used to have a decent salary, which was not enough to support a family. go down.

There are various reasons for this, mainly because of the war, and secondly, all the salaries paid by Tsinghua University have been converted into legal currency.

The fiat currency thing...

It's hard to say.

Yu Hua does not want to see such a situation happen, so he is leaving a sum of money for Master's family. In the future, the road and life in Kuncheng, Yun Province will be better at least. You must know that Master's family has four children and two elderly people. Together with his husband and wife, there are eight in total, all supported by Master's salary.

This is also the reason why Master's standard of living cannot be improved even though he is a full professor at Tsinghua University with a considerable salary.

silence.

There was only Wu Xiaoyuan's breathing in the main room. She was not good at words. After hearing Yu Hua's words, she didn't know how to speak. Her lips trembled slightly, and her usual soft eyes gradually became wet: "Xiaohua..."

The words were already a little choked up.

Yu Hua's remarks really touched her heart and moved Wu Xiaoyuan very much.

"Master, I hope you don't tell Master, otherwise, he will definitely not accept it." Yu Hua said softly.

"Xiaohua, your 100 yuan ocean, my teacher will take good care of it for you." Wu Xiaoyuan resisted the tears rolling in his eyes, took a deep breath, and nodded towards Yu Hua.

Now, there is only one feeling in her heart - Luo Geng, you really found a very good student.

Yu Hua smiled and nodded without saying a word. In fact, the remaining 100 Yuan Dayang was reserved for the master's family. The so-called "reserve for emergencies" was just an excuse for him. Will not accept another 390 oceans.

As the saying goes, true feelings cannot be retained, and routines are popular.

……

The mother Wu Xiaoyuan carried the whole box of silver dollars into the bedroom and put them away properly. Yu Hua entered the second bedroom to study and waited quietly. At about [-]:[-], Master Hua Luogeng arrived home, and the three of them had a meal and chatted.

Afterwards, the master and apprentice finished eating as usual and entered the study together.

Yu Hua ordered a large front door that was secretly filial piety from his wife, and then handed it to Master Hua Luogeng.

Seeing this, Hua Luogeng laughed and shook his head. He took the cigarette with his right hand and brought it to his mouth, took a breath, and exhaled white smoke comfortably, and said with concern, "You boy... have you finished the registration procedures for school?"

Yu Hua nodded and said, "It's all done."

"How did you learn during this period of time, did you slack off?" Hua Luogeng continued to ask.

"Of course not, how dare a student, I have read all the notes you gave, Master, and I have learned a lot." Yu Hua shook his head and smiled.

"Didn't you plan to attack Goldbach's conjecture before? Repeat Mr. Lacey's 5+7 and 4+9 to prove it, and put the chalk in the second drawer." Hua Luogeng smiled when he heard it, and pointed with his right hand holding a cigarette. Study blackboard, arrange study test.

"Yes."

Yu Hua nodded, got up and picked up the chalk, went to the blackboard in the study, and began to repeat the latest results of Goldbach's conjecture this year-5+7 and 4+9 with his right hand.
