A master of scientific quantification who studies nuclear fusion....
Li Donglai suddenly became interested, walked over and said with a smile: "Professor Hans Bethe, are you nervous?"
"A little bit... uh... you say?" Professor Hans Bethe thought it was an acquaintance saying hello. When he turned around and saw a strange black-haired young man, he was a little confused.
Li Donglai stretched out his hand: "Li Donglai, doctor."
"Ah, I didn't expect you to be so young, Doctor Li Donglai." Professor Hans Bethe reached out his hand enthusiastically and held Li Donglai's hand tightly: "The cephalosporins you developed have saved countless people. Here, I want to
I express my sincerest gratitude to you.”
"Isn't the work of us scientists just to make mankind's tomorrow better? I'm just completing my work." Li Donglai said with a smile.
"Let mankind have a better tomorrow..." Professor Hans Bethe repeatedly savored these words, a glimmer of light flashed in his eyes, and a slight look of shame appeared on his face: "To tell you the truth, although I work in the scientific community
Over the past few decades, I have made some achievements, but I have always felt that my work does not seem to have much meaning. Today I discovered that I have been working hard to make a better tomorrow for mankind, and my goal is noble.
....”
It seems incredible that Professor Hans Bethe did not know his original goal of studying science, but it is a very common state among scientists in this era.
In this era, most scientists in Europe and the United States are believers and have received theological education since childhood. Science is contrary to theology. In a strict definition, studying science is tantamount to disobeying the omnipotent and omniscient God.
Most of these scientists do not have too lofty ideals, they just invest in scientific research out of curiosity and curiosity about the mysteries of the universe.
They are not proud of their work and have no clear goals.
Li Donglai's statement that "the work of scientists makes mankind's tomorrow better" perfectly solves the problem of the meaning of scientists' existence from a philosophical level.
"Dr. Li, you are indeed a wise man." Professor Hans Bethe, who was awakened, was naturally generous with his kind words for Li Donglai.
"Professor Hans Bethe, your work also deserves my respect, especially your research on nuclear fusion."
Li Donglai brought the topic to nuclear fusion, which aroused the interest of Professor Hans Bethe even more. He talked about his recent achievements in work.
After listening, Li Donglai nodded and said: "It seems that we are still a long way from achieving controllable nuclear fusion."
"Controllable nuclear fusion..." Professor Hans Bethe's eyes suddenly widened and he stared at Li Donglai with incredible eyes: "You mean, we can really control the power of stars through science?
"
As an expert in the study of nuclear fusion, Professor Hans Bethe knows how demanding the conditions are to achieve nuclear fusion. It requires a high temperature of millions of degrees and a high pressure of millions of Pascals to make the nuclear attraction
exceed the electrical repulsion, allowing them to achieve fusion.
Under such difficult conditions, the benefits are huge. According to theory, it can be calculated that after nuclear fusion of a few grams of reactants, it is possible to produce one terajoules of energy, which is approximately what a person in a developed country can produce in 60 years.
energy required.
Since nuclear fusion was recognized in the 1930s, scientists have sought to replicate and exploit it.
But there has been no progress.
Professor Hans Bethe, one of the best, has been completely disappointed after experiencing countless failures.
Li Donglai smiled: "I'm just a doctor and don't know much about controllable nuclear fusion."
"..." Professor Hans Bethe felt as if he was being played.
"It's just that I have an interesting idea." Li Donglai continued: "The biggest difficulty in controllable nuclear fusion is, first, safety. If it cannot be controlled and a violent reaction occurs, if it cannot be controlled, we are likely to create a
star. Second: The reaction requires ultra-high temperatures, millions of degrees, which cannot be tolerated by any container made of current materials, so no container can hold the reactants."
Professor Hans Bethe nodded frequently. Being able to understand this knowledge shows that this doctor is no longer a layman.
In fact, they already have the corresponding technology on how to generate high temperature and high pressure. But they have no idea where to generate high temperature and high pressure.
They spent tens of millions of pounds of research funds, and all they got in the end was a pile of scrap metal.
Does this doctor really have good ideas?
"Magnetic confinement." Li Donglai said a word that did not exist in this era under the expectant gaze of Professor Hans Bethe.
"Magnetic confinement...?"
Professor Hans Bethe's face was full of suspicion.
Li Donglai explained: “In the early stages of nuclear fusion, all materials involved in the fusion will turn into plasma in a high-temperature and high-pressure environment.
We can use high-energy magnetic fields to constrain the movement of charged particles in plasma, so that high-temperature plasma can react without touching the container wall."
genius!
Genius idea!
This is something only a genius can come up with!
Using the characteristics of ions and using high-energy magnetic fields to constrain the movement of ions is called magnetic confinement.
Professor Hans Bethe was keenly aware that this method is theoretically feasible.
The problem that has troubled hundreds of high-energy physicists for more than ten years was solved by a doctor's "interesting idea".
If he hadn't been so old, he would have jumped up from the ground by now.
"Doctor Li, Professor Li Donglai, your idea is really valuable."
Professor Hans Bethe took out paper and pen from his pocket and wrote down the method of magnetic confinement with paper and pen. Although he thought he had a superior memory and a photographic memory, he did not dare to take the risk of forgetting. Just because of magnetic constraint
The method is really too valuable.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Li Donglai chuckled. Magnetic confinement is the method used by later generations to achieve controllable nuclear fusion.
Tokamak devices and stellarator devices use magnetic confinement internally. Although the time to achieve nuclear fusion can only be calculated in seconds, it is always a way out. If the layout can be planned in advance, a large number of scientists can be gathered to conduct research.
, it may not be impossible to achieve true controllable nuclear fusion.
The magnetic confinement theory given by Li Donglai is only rudimentary. If it is to be transformed into reality without specific technical guidance, it is almost impossible to realize it in this era... At this time... it may be able to deceive a large number of high-energy physicists.
To the country.
Comrade Zhou stood not far away. Although he didn't know what Li Donglai said, which made Professor Hans Bethe as excited as a child, he always felt that Li Donglai looked like a hunter, and Professor Hans Bethe
Like an innocent little white rabbit.
"Doctor Li, don't worry, if we can develop controllable nuclear fusion, your name will definitely be at the top of the list." Professor Hans Bethe said sincerely.
"Don't worry, scientific research does not happen overnight..." Li Donglai smiled: "Actually, I have already done preliminary research on the magnetic constraint theory. If we have time, we can study it in depth."
"Ah, great. Magnetic confinement requires a vacuum chamber. The production of the vacuum chamber..."
It must be said that Professor Hans Bethe is a talented scientist. As soon as he accepted the concept of magnetic confinement, he immediately realized the key to the problem.
Professor Hans Bethe wanted to say something more, but the staff next to him reminded him: "Professor, it's time to award the prize. It's your turn."
"Award? What award?" Professor Hans Bethe's eyes widened and he felt angry because he was interrupted. He was discussing the mysteries of the universe with Dr. Li. This is the most beautiful thing in life.
Professor Hans Bethe has always been amiable and well-known in the scientific community as a good gentleman. This is the first time that the staff have seen him angry.
He was stunned for a moment, and then continued: "It's the Nobel Prize in Physics, and His Majesty is already waiting on the stage..."
"...It seems that there is such a thing...Dr. Li, I'm really sorry. Let's discuss it further after I get the medal."
After Professor Hans Bethe finished speaking, he couldn't wait to get on the stage.
The host had already introduced the life story and main achievements of Professor Hans Bethe, and his appearance on the stage attracted a burst of warm applause.
Professor Smith, who was in charge of awarding the award, walked up to Professor Hans Bethe with a microphone: "Old friend, today is your highlight moment. You have been nominated dozens of times in a row, and today you finally succeeded in reaching the top of physics.
, you must have a lot to say."
"Speech, oh no, I have been preparing my speech for so long, and I seem to have forgotten all about it... And the text of my speech seems to be in my bag, and I forgot to bring it with me..."
Professor Hans Bethe's face changed drastically when he heard this, and there was a lot of sweat on his forehead. He put his right hand into his pocket and took it out again. There seemed to be no place to put it.
Professor Smith saw Professor Hans Bethe's nervousness and comforted him: "It's okay, old friend, you just need to express your feelings."
Yes, just tell me your thoughts.
Hans Bethe, you are a world-famous scientist, you can do it!
Professor Hans Bethe calmed down, took the microphone, and said loudly to the audience: "I am deeply honored to be the winner of this year's Nobel Prize in Physics. When I was young, I looked up at the stars and was struck by
I was deeply attracted by the mysteries of the universe.”
The scientists in the audience lowered their eyelids and looked like they were sleeping. There was nothing they could do about it. This was a standard way for scientists to speak. It was like the protagonist in a martial arts novel who fell off a cliff and would inevitably find the martial arts secrets and become the master of martial arts.
Like a great hero.
Who hasn’t had childhood yet, who hasn’t seen the stars...
Professor Hans Bethe's speech was so boring that even the king, who was sitting on the throne waiting for the award, couldn't help but look at the staff holding medals, hoping that the speech could end earlier.
"...My love for science led me to embark on the path of scientific research. However, after I became successful and famous, I always felt that my goals and motivations were not sufficient."
Professor Hans Bethe changed the subject, and the scientists in the audience suddenly became energetic.
What does this old professor want to do? Apart from interest, what else can he do to study science?
Is it for God?
Professor Hans Bethe paused, glanced around the hall, straightened his body, and had a look of pride on his face: "Backstage just now, I discovered that all the research work of our scientists is actually to improve human health.
Tomorrow will be better!"
"Wow"
There was a lot of discussion in the audience.
"Making mankind's tomorrow better... This goal seems much nobler than childhood interests."
"Don't tell me, it's true. Everything we do has invisibly promoted the development of mankind."
"Steam engines, fertilizers, airplanes, automobiles...the world has changed dramatically because of the results of our work."
"...Ah, I didn't expect that I would be so noble. I will tell my daughter immediately after I return. His father studies science in order to make mankind's tomorrow better."
"Who is that Eastern scientist? He helped me find the meaning of life. I want to thank him very much."
Human beings are intelligent creatures, and all decisions they make need to have clear motives.
Some motives are full of selfishness, such as for life, for money, for reproduction...
Some motives are more lofty, such as for all mankind, for the future of mankind...
Subconsciously, people always want to become taller.
As soon as the statement "scientific research is for a better tomorrow for mankind" was put forward, it immediately caused a sensation at the venue.
Professor Hans Bethe looked at the excited scientists and felt a little regretful. Did he steal Dr. Li's limelight?
After all, this statement was put forward by Dr. Li, and he is just a plagiarist.
Backstage, Comrade Zhou stood at the door, looking at the situation in the hall, and frowned: "Comrade Li Donglai, this old professor, doesn't seem to understand the rules. After all, it was you who proposed it first..."
Li Donglai took a sip of tea, asked the waiter who served the tea to leave, and said with a smile: "It's just a life motto, what's the big deal. Professor Hans Bethe is of great use to us."
Great use... Comrade Zhou remembered the controllable nuclear fusion that Li Donglai had just discussed with Professor Hans Bethe. His heart skipped a beat. Could this genius doctor want to study controllable nuclear fusion?
No, it's impossible....
Even the most advanced research institutes abroad have spent countless funds and failed to achieve a breakthrough in controllable nuclear fusion.
.....
On the stage, Professor Hans Bethe pressed his hands down to signal the scientists to quiet down.
"Here, I would like to apologize to Dr. Li Donglai. The phrase "for a better tomorrow for mankind" was actually proposed by Dr. Li Donglai.
This remark once again caused a stir.
"Li Donglai? The Nobel Prize winner in medicine from the East."
"I didn't expect that he could be keenly aware of the noble ideals of our scientists."
.....
Professor Hans Bethe continued: "In fact, I just got a genius idea from Dr. Li. Here I decided to suspend research in scientific quantification and prepare to devote all my body and mind to the research of controllable nuclear fusion.
中.If you encounter any problems, please stop disturbing me."
The audience was suddenly speechless.
.....
In the last row of the venue, a blond woman who looked like a reporter frowned, and a haze flashed in her eyes.
