Scholar’s Starry Sea

"Continue to take the particle motion trajectory as an example. Do you know who introduced the Mathematics description of the particle motion trajectory?"

"Professor Calero. "Wu Bin replied.

After listening to Wu Bin’s answer, Professor Pan Jianwei was stunned, "Have you read his paper?"

"Yes, his geometric curve research paper and the concept of curvature I I've all visited them."

"Why would you want to read such an old paper?" Professor Pan Jianwei asked with interest.

"I once looked up a 1935 document when I was studying black phosphorus, but even though it was a paper more than 80 years ago, the research in it still has great significance for me. Therefore, I realized that the wealth of knowledge is really a very eternal thing. After that, I have a strong interest in those classic papers."

"hahaha." Professor Pan Jianwei couldn’t help laughing after hearing this. “It’s no wonder that those professors in the school praised you. Now I understand it a little bit.”

“Then since you know Clairo, it’s important to his academic career. You should know something too, right?"

Wu Bin thought for a while and replied: "Specifically...I don't fully understand, I only know that he was elected a member of the French Academy at the age of 18."

p>

How hard-core this academician of the Franco Academy is!

To put it simply, Madame Curie, who has won two Nobel Prizes, is not eligible to be selected because she is not educated enough.

The Second Generation Officials among Peak scientists, De Broglie put forward the concept of matter wave in the Academician paper in 1924, and then won the Nobel Physics Prize in 1929, but it was not until more than a decade. Only later did he rely on the operation of his big brother, the mayor, to finally be elected as an academician of the Franco Academy.

This is enough to show how enchanting Clairo is to be elected to this Academy at the age of 18.

"Okay, since you know that, I won’t introduce more. Well, let me give you an analogy. Since you have studied Quantum mechanics, you must know that there is an important concept called bubble. Profit matrix."

This time, Professor Pan Jianwei did not intend to ask Wu Bin any more questions, but went on directly.

"Pauli wrote two papers during the holiday when he was waiting for the admission notice after the college entrance examination, which laid the foundation for him as a relativity expert."

"So he just went When registering at the University of Munich, Sommerfeld, a well-known Munich professor, told him directly that you have the level of an Academician degree, but according to German regulations, it takes at least six semesters to apply for an Academician degree after entering the university. "

Speaking of this, Professor Pan Jianwei glanced at Wu Bin suddenly, as if implying something.

"After that, Pauli didn’t graduate early, but Sommerfeld told him that you can’t just hang around with me for six semesters, so I found him a little job, and that job is just a job. The German Mathematical Encyclopedia writes on the topic of relativity."

"So Pauli, who was just in his freshman year, began to write the literature on the theory of relativity. It was officially published in his junior year. The 237 pages of Relative to the essay book, it is still a classic in this field."

"Well, I have read it. It is indeed very good." Wu Bin tried hard nodded.

"Okay, I know you are also excellent." Professor Pan Jianwei smiled nodded, "Then I will ask you another question, do you know the relationship between Pauli matrix and the theory of relativity?"

"You mean Pauli matrix plus unit 2*2 matrix is ​​the distance formula in the theory of relativity?"

"……"

Listen to Professor Pan Jianwei After being silent for a while, "Although I have used genius as an example, if you think about it carefully, these all are things that European high schools and freshmen should learn, but there are too many people in our country who have been for more than ten years. After the professor, I suddenly understood a little bit."

Looking at Wu Bin’s serious nodded, Professor Pan Jianwei smiled helplessly and said: "Actually, I want to say something to you, such as To devote yourself to a basic science like Physics, you should broaden your perspective. Don’t think that you don’t need to understand the theory of relativity if you learn condensed matter experiment Physics."

" Find out how deep the water is, so that might make you calm down and do something."

"But for you, these warnings seem a little redundant."

Wu Bin hurriedly waved his hand after listening: "Why, I will remember the good words of the professor's Gold Jade in the heart."

"Well... it's not a bad thing to memorize a few more sentences." Professor Pan Jianwei is satisfied. Nodded, "Let’s talk to you about my own field. We are now studying the most microscopic world, but we need the most macroscopic knowledge about the entire universe."

"So in my heart, Physics is like a snake-eating tongue, a snake-eating tongue. It is a Physics problem on the cosmic level. It is assumed to be Physics on the level of elementary particles. The most macroscopic head holds its most microscopic tail."

After hearing this sentence, Wu Bin couldn't help thinking.

"Physics? Or...philosophy?"

...

Interesting chats always make time pass very fast, wait for the fifth cup of tea Wu Bin finally couldn't help but want to go to the toilet.

When Wu Bin came back from the toilet, Professor Pan Jianwei stood up and said to him: "It's almost nine o'clock, let's have a potluck together."

"Okay." Wu Bin happy nodded and said.

During the meal, Professor Pan Jianwei raised a new topic, "Physics studies the invariance in change. A simple Tim from a Mathematics paper clearly clarifies the core ideas of Physics. Now."

"Do you think Mathematics is difficult?" Professor Pan Jianwei took a bite of the Red Braised Pork and asked Wu Bin.

"Difficult, but very interesting." Wu Bin lifts the head seriously.

Professor Pan Jianwei nodded slowly after listening, "Many people often say that it is indeed very difficult to require Physics experts to learn so many Mathematics like Mathematics experts. Even Hilbert Suffice it to say something that is very famous and very helpless."

"Physics is too difficult for a Physics scientist!"

"Do you know why he said that?" From these hours of conversation, Professor Pan Jianwei's interest has changed. What he is seeking now is not to ask the big boy in front of him, but to get a response to every question he raises seems to be a pleasant thing.

"Because he knows that Physics needs a lot of Mathematics, which is difficult for Physics scientists to grasp. In fact, many people have talked to me about the relationship between Mathematics and Physics, and I also have some of my own Thoughts."

"Oh? Tell me about it." Professor Pan Jianwei asked expectantly.

"A lot of Mathematics knowledge is indeed difficult for Physics scientists to grasp, but on the other hand, about equations, or the beauty of Mathematics, is really not what Mathematics experts can see. The true beauty of Mathematics must reflect Our real Physics world, so we still need to use Physics to see where it is beautiful."
