Chapter 367: The Flint Library is a place full of treasures (three / three ...

Although some things are public information, after all, those things have been organized by others.
What Lu Zhou hopes to see is Leyman Spitzer's initial idea of ​​a stellar when he designed the stellar.
At the same time, it is a theoretical model set up from the perspective of a pure physicist.
"Lyman Spitzer's manuscript?" Edward Witten touched his chin and thought for a moment. "I haven't really paid much attention to this research, but I remember he donated the manuscript to the Advanced Research Institute at the end These things were donated to the Shizuku Library at the beginning of the millennium. If you are interested, you should be able to find them in the Shizuku Library's collection room. "
Lu Zhou: "Are you at the Shishi Library? Thank you."
"You're welcome," Witten smiled, and continued. "Actually, if you are interested in stellarators, why not consider visiting relevant research institutes for communication? Now no one is studying this thing in Princeton. Instead, Stanford and MIT, as well as California Institute of Technology, have studied this stuff a lot. "
Lu Zhou: "I will consider it if necessary, but before that, I have to determine my research direction."
The concept of controlled nuclear fusion is too big. Although the general description is only five words, the research project involved is not less than five pages in name.
In a sense, one of the reasons why Lu Zhou wanted to borrow the manuscript of Lehman Spitzer was to get inspiration from it.
After listening to Lu Zhou's words, Witten took a sip of coffee and said with a smile, "I wish you could find what you are looking for."
"I borrow your good words."
After leaving this sentence with a smile, Lu Zhou said goodbye to Witten and walked outside the Institute of Higher Education for an instant.
...
There are such a group of scholars in the academic world who, while engaged in rigorous research work, still maintain a wild imagination.
For the things that most people seem strange, their first thought is not to prove that this is impossible from a professional perspective, but to try to give fantasy a realistic meaning from a scientific perspective.
Lehman Spitzer is such a person.
In addition to him, Freeman Dyson, who proposed the Dyson ball concept, and Ziolkowski, who proposed the space elevator concept, can be included in this column.
Compared to the latter two, Lehman Spitzer is obviously not famous, but no one can ignore his influence in physics, especially astrophysics.
Because it was his earliest proposal to put the telescope into space to eliminate the obscuration effect of the earth's atmosphere, which later led to the birth of the "Hubble" space telescope.
To commemorate him, the last space telescope, the Spitzer Space Telescope (SST), planned by the Large Orbiting Observatory was named after him.
After saying goodbye to Witten, Lu Zhou went to the collection area of ​​the Shishi Library and found the librarian here.
Responsible for managing the collection here is an old man who looks somewhat rigid and weird.
Although all kinds of weirds are often seen in Princeton, it is quite rare for mystics to wear pajamas like work clothes and wear them in the library.
Especially the turbid eyes make people wonder if he is suffering from Alzheimer's disease, can he hear what others are saying.
However, Lu Zhou was surprised that after listening to his visit, the old man not only did not have any dementia reaction, and even quickly came to a two-story bookshelf and took it off with the help of a ladder A thick note with leather on the cover.
Returning to the original wooden counter, the old man turned his face and handed the notebook to Lu Zhou.
"This is what you want."
"Thank you."
Lu Zhou thanked him and reached out to pick up the manuscript.
However, the old man didn't make him do what he wished, as if fishing, and his outstretched hand retracted at an exaggerated speed.
Lu Zhou :? ? ?
Indifferent to the floor face, the old man's dry hand stretched out again.
"This is the wealth of civilization. Please keep it safe."
It seemed that he was just going to give himself a piece of advice.
However, Lu Zhou noticed that the old man's hand holding the notebook kept shaking, as if waiting for an opportunity.
"I see ... Can you give it to me now?" Lu Zhou looked strangely at the old man in front of him. Lu Zhou didn't reach out to pick up the notebook.
It always feels like the old man, it's the same as intentionally teasing him.
Seeing Lu Zhou was not fooled, the old man's eyes flashed a disappointment of failure, and he coughed softly, and continued to speak with a grimace.
"Of course you can ... but before that, you have to swear, what it looked like when you borrowed it, and what it looked like when you returned."
Lu Zhou raised three fingers.
"I swear……"
"Not swear to me," the old man took out a Bible he didn't know where to buy from the side, and looked at Lu Zhou seriously. "You must swear on it."
Looking at the Bible, Lu Zhou looked helpless.
What's the use of having an atheist swear on this thing?
It would be better to give him a book of Newton's "Mathematical Principles of Natural Philosophy" or Einstein's "Unified Field Theory", which can be a little more solemn.
However, in order to save time, Lu Zhou didn't have as much nonsense. He put his hand on the cross of the Bible and said it honestly as he said.
"I promise what it looked like when borrowed and what it looks like when returned."
Although he was not satisfied with Lu Zhou's solemn attitude, the old man nodded reluctantly after he completed this weird ceremony, and handed the manuscript to him.
"Hope you remember your promise."
"I will."
Without stopping for a moment, after receiving the manuscript, Lu Zhou immediately walked to the reading room next to him ...
...
Because time has given it the attributes of its cultural relics, even if the book was borrowed from the Shishi Library, Lu Zhou could not really take the manuscript out of the library, and only read it in the reading room of the collection area.
For some documents with a history of more than 100 years, before they can be borrowed, they have to pass the relevant qualification assessment and wear special gloves.
However, this note is relatively "new", with a history of more than sixty years.
Spreading it out on the table, Lu Zhou studied it from the first page.
It's not easy to fully understand the content, and Leyman Spitzer's notes are just like his wild imagination. At the same time, the handwriting is scribbled and mixed with some unclear meaning stick figures.
I do not know what kind of mood he was in, wrote that will, and donated all his manuscripts to the Princeton Advanced Institute.
Lu Zhou felt that if he replaced himself, he would definitely not allow such "unclear" things to remain in the world ...
It took an afternoon for Lu Zhou to see it from beginning to end.
Although it is difficult to understand in many places, after reading it, he still felt a lot of benefit.
In particular, Leyman Spitzer's judgment on the front-end technology to complete the final simulation of the stellar is basically consistent with his own conclusions.
"... It's hard to imagine, it turned out to be something from sixty years ago." After closing the old manuscript, Lu Zhou couldn't help but sigh and gave an evaluation of his own.
Even if it is put in the present, if you refine the ideas in this note and the design concept of a stellar, you can still get a paper of great academic value.
Of course, it's been sixty years, and someone must have done this job.
Putting the manuscript aside and watching the contents arranged on the notebook, Lu Zhou was lost in thought.
Controllable nuclear fusion is a huge project, and it is enough to arouse his interest both in its own meaning and the broad prospects behind it.
The problem is that he needs to choose a suitable entry point.
Is it a superconducting material closer to room temperature?
Or, from a mathematical point of view, try to study "the law of the motion of plasma in a stellarator"?
The first two are applied, the latter is theoretical, no matter which difficulty it is.
In particular, the latter, EbookFREE.me, involves the study of fairly complex plasma turbulence. It can be said that this is the most difficult and complicated one of the many research directions on the Navier-Stokes equation.
Because so far, what people can do with plasma is just "diagnostics", not "measurement."
However, once this problem is effectively solved, it will not only promote the progress of nuclear fusion engineering, but also the study of the Navier-Stokes equation is very instructive ...
It was so silent, it took about ten minutes.
There was a smile at the corner of his mouth, and Lu Zhou raised his pen and drew a circle on the line of "the law of the movement of plasma in a stellar".
Closing the notebook in his hand, he took the manuscript and his belongings and stood up from the chair.
Sure enough, it is still more challenging and more suitable for me.
Since solving Goldbach's conjecture, there has never been any question that cannot be answered, which has made him so excited ...
