Scholar’s Advanced Technological System

Some things are publicly available, but those things are sorted by others.

What Lu Zhou hopes to see is the original idea of ​​Leyman Spitzer at the beginning of the design of the imitation star.

At the same time, it is also a theoretical model set out from the perspective of a pure physicist.

"Lehman Spitzer's manuscript?" Edward Witten touched his chin and thought for a moment. "I really didn't pay attention to this research, but I remember that he finally donated the manuscript to the Institute of Advanced Studies. These things were transferred to the Rock Library for preservation at the beginning of the millennium. If you are interested, you should be able to find them in the library of the Rock Library."

Lu Zhou: "At the Rock Library? Thank you."

"You're welcome," Witten smiled and continued. "Actually, if you are interested in imitations, why not consider visiting relevant research institutions? Now there is no one in Princeton who is studying this thing. Instead, Stanford and MIT, as well as Caltech, 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 that the name of the project is no less than five pages.

In a sense, one of the reasons why Lu Zhou hopes to borrow Lehman Spitzer's manuscript is to hope to get inspiration from it.

After listening to Lu Zhou’s words, Witten took a sip of coffee and said with a smile: “I hope you can find what you are looking for.”

"Take your good words."

After laughing and leaving this sentence, Lu Zhou and Witten quit, and kept walking outside the Institute of Advanced Studies.

......

There is such a class of scholars in academia who, while engaged in rigorous research work, still maintain the imagination of the sky.

For the things that ordinary people seem to be ridiculous, their first thoughts are not inclined to prove the impossibility of this matter from a professional point of view, but to try to give fantasy to the meaning of reality from a scientific point of view.

Lehman Spitzer is such a person.

In addition to him, Freeman Dyson, who proposed the concept of Dyson Ball, and Tsiolkovsky, who proposed the concept of space elevator, can be included in this list.

Compared to the latter two, Lehmann Spitzer is clearly not famous, but no one can ignore his influence in physics, especially astrophysics.

Because at the earliest, he proposed to put the telescope into space to eliminate the shadowing effect of the Earth's atmosphere, which later led to the birth of the Hubble Space Telescope.

To commemorate him, the Spitzer Space Telescope (SST) telescope, the last space telescope planned by the Large Orbital Observatory, was named after him.

After bidding farewell to Witten, Lu Zhou went to the library area of ​​the Rock Library and found the librarian here.

Responsible for managing the collection here is a stereotyped and quirky old man.

Although there are a lot of strangers in Princeton, it is quite rare to use nightwear as a workwear and a mystic in the library.

Especially the turbid eyes, people can not help but wonder if he is suffering from Alzheimer's disease, can not hear what others said.

However, Lu Zhou was surprised that when the old man listened to his intentions, he did not have any reaction to dementia. He even quickly walked to a two-person high bookshelf and took it off from the top with a ladder. A thick note with a cowhide cover on the cover.

Going back to the original wooden counter, the old man squinted and handed the notebook in his hand to Lu Zhou.

"This is what you want."

"Thank you."

Lu Zhou thanked him and reached for the manuscript.

However, the old man did not make him wish, just like fishing, the hand that stretched out instantly shrank back at an exaggerated speed.

Lu Zhou:? ? ?

Indifferent to the floor, the old man’s dry hand re-stretched.

"This is the wealth of civilization, please keep it safe."

It seems that he is only going to give himself a piece of advice.

However, Lu Zhou noticed that the hand of the old man holding the notebook has been shaking, just like waiting for an opportunity.

"I know... can you give it to me now?" Looking at the old man in front of him, Lu Zhou did not reach out to pick up the notebook.

Always feeling the old man, is deliberately teasing him to play.

Seeing that Lu Zhou was not fooled, the old man’s eyes flashed a trace of disappointment that he could not succeed. He coughed softly and continued to say his face.

"Of course... but before that, you have to swear, what it looks like when you borrow it, and what it still looks like when you return."

Lu Zhou erected three fingers.

"I swear……"

"Not swearing to me," the old man took a Bible from where he did not know where to buy it, and looked at Lu Zhou seriously. "You must swear to it."

Looking at the Bible, Lu Zhou’s face was helpless.

What is it for an atheist to swear to this thing?

It is better to give him a Newton's "Mathematical Principles of Natural Philosophy" or Einstein's "Unified Field Theory", which can be slightly more solemn.

However, in order to save time, Lu Zhou did not have as much nonsense, but as he said, put his hand on the cross of the Bible and said in an honest tone.

"I promise, what it will look like when I borrowed it, and what it still looks like when I return."

Although the attitude of Lu Zhou was not very satisfactory, but after he completed this weird ceremony, the old man nodded reluctantly and handed the manuscript to his hand.

"I hope you remember your commitment."

"I will."

I didn’t stop for a moment. After taking over the manuscript, Lu Zhou immediately walked to the reading room next to him...

......

Since time has given the attributes of its cultural relics, even if the book was borrowed from the Rock Library, Lu Zhou could not bring the manuscript out of the library, but only in the reading room of the collection area.

If it is a document of hundreds of years of history, it is even necessary to pass the relevant qualifications and wear special gloves before borrowing.

However, this note is relatively "new" and only has a history of more than 60 years.

Spread it on the table, Lu Zhou started from the first page and studied it carefully.

It is not easy to fully understand the contents. Lehman Spitzer's notes are just like his imaginative imagination. He is also scribbled with some unrecognized stick figures.

I don't know what kind of mood he was out of, write down the will, and donate all his manuscripts to the Princeton Institute of Advanced Studies.

Lu Zhou feels that if he is replaced by himself, he will certainly not allow this "unknown" thing to stay in the world...

It took an afternoon for Lu Zhou to see it from the beginning.

Although many places are difficult to understand, after reading it, he still feels a lot of benefits.

Especially for the pre-engineering of the final vision of the imitation star, Lehmann Spitzer's judgment is basically consistent with his own conclusions.

"...I can't imagine, this turned out to be something sixty years ago." Closing this old manuscript, Lu Zhou could not help but sigh and give his own evaluation.

Even if it is placed now, the ideas in this note and the design concept of the imitation star can be extracted, and a paper with academic value can still be obtained.

Of course, this has been in the past sixty years, and this work must have been done.

Putting the manuscript aside and looking at the contents of the notebook, Lu Zhou fell into thinking.

Controllable nuclear fusion is a huge project, both in its own meaning and in the broad prospects behind it, enough to arouse his interest.

The problem, however, is that he needs to choose a suitable entry point.

Is it a superconducting material that is closer to normal temperature?

Or, from a mathematical point of view, try to study "the law of motion of plasma in a star-like device"?

The first two are the application level, while the latter is the theoretical level, no matter which difficulty is not small.

In particular, the latter involves the study of quite complex plasma turbulence phenomena. It can be said that this is the most difficult and complicated part of the many research directions of the Navier-Stokes equation.

Because so far, the measures that people can take on plasma are just "diagnosis" rather than "measurement."

However, once this problem is effectively solved, not only will the progress of the nuclear fusion project be promoted, but the research on the Navier-Stokes equation is also very instructive...

It’s so silent, the time is probably about ten minutes.

The corner of the mouth suddenly evoked a smile. Lu Zhou raised the pen and drew a circle on the line "The law of motion of the plasma in the star-like device."

Closing the notebook in his hand, he took the manuscript and his own things and stood up from the chair.

Sure enough, it is still a more challenging problem, more suitable for yourself.

Since the settlement of Goldbach’s conjecture, there has never been a question that cannot be answered, so that his heart has passed...
