Chapter 180 I’m not as good at physics as math
Listening to Professor Svensay's class, Lin Xiao gradually fell into it.
He knew all these basic knowledge. He had read a lot of physics books, and he knew a lot about high-energy physics, a subject that sounded very interesting.
After all, it sounds pretty cool to accelerate extremely tiny particles through long pipes to speeds of thousands or even tens of thousands of kilometers per second, and then let them collide with each other.
However, Professor Svensey's class was very lively and interesting, and he also had some other cutting-edge ideas, so Lin Xiao was also fascinated by it.
This is indeed a teacher from the Ecole Normale Supérieure in Paris.
Of course, the depth and difficulty also make it difficult for some students here.
After all, high-energy physics requires not only images, but also a variety of mathematical tools.
Therefore, the requirements for mathematics are still very high. The students present looked at the blackboard full of images and mathematical formulas. Those with strong ability were able to understand it, while those with slightly less ability could only study by themselves after going back.
Of course, for Lin Xiao, a mathematician, these are not difficulties.
In this way, time passed quietly, and the lesson was finished.
When the class was over, Lin Xiao stood up.
Well, this way I won’t have lied to my father.
He really taught a lesson.
Later, when he was going to say hello to Henry, he found that he walked up and found Svensay.
Seeing this scene, Lin Xiao couldn't help but raise her eyebrows. Apparently, Svensey was Henry's tutor, which could explain why Henry came to attend this class.
Then he smiled slightly and walked up, while Henry took a few pieces of paper and asked Svensay questions.
"...Professor, I encountered a problem in my research. I factored the unpolarized fully differential Drell-yan cross section, but I still can't figure out why the coefficients of A5-A7 always jump around.
, I can’t analyze at what level they are zero, they are just too naughty.”
Svensey took the pieces of paper from him and said at the same time: "Is there any problem with your analysis of the data? Are there any errors in the numbers?"
Henry spread his hands helplessly: "I have checked it three times and I can confirm that there is no problem, so there is really no other way but to come to you for advice."
Svensey shook his head, "So there's something wrong with your math?"
Then he watched Henry's process.
Lin Xiao, who had been watching from behind, saw that the two of them were no longer talking, so he reached out and patted Henry.
Henry turned around and was stunned when he saw Lin Xiao.
"Lin? Why are you here!"
Lin Xiao smiled and said: "Of course I'm here to listen to the class."
Henry was stunned again, and then smiled: "It seems that the great Professor Swansey has also attracted our mathematical geniuses."
Next to him, Svensey said abruptly: "Don't say that everywhere outside."
"Ah, of course not." Henry waved his hand, "I will only say that in front of you."
Lin Xiao couldn't help but smile. This guy simply said openly, "Professor, I want to lick you."
"Okay, Lin, let's not disturb the professor. Let's talk aside."
At this time, Henry pulled Lin Xiao again and came to the side.
"You're not really interested in our high-energy physics, are you?" Henry asked.
"certainly."
Lin Xiao spread his hands: "As long as there is mathematics, I will be interested."
"All right……"
Henry said helplessly: "Sometimes I really envy your talent in mathematics. If my mathematics were half as good as yours, no, one-third, one-fourth, just one-fourth better, how could I be admitted to the paper?"
It’s hard to live with.”
Lin Xiao said with a smile: "For a quarter of me, it is probably to prove the twin prime conjecture and Goldbach's conjecture, plus find out the distribution rules of Mersenne prime numbers, and prove that there are infinitely many prime numbers in the Fibonacci sequence.
That’s a quarter of the total.”
Henry opened his mouth, this...
Is it equivalent to saying that a quarter of Lin Xiao’s gold content is equivalent to a world-class mathematical problem?
He simply slumped on the back of the chair. It was better to leave it alone.
"Okay, ten percent."
Lin Xiao laughed and said: "Okay, cheer up, at least Einstein is not particularly good at mathematics. Maybe you will be the next Einstein?"
Henry rolled his eyes, "Then you have to make an argument based on the theory of relativity first. What is the difference between my mathematics compared to yours and Einstein's mathematics compared to yours."
"Well, we can discuss this from the perspective of general relativity and quantum mechanics."
Henry sat up, stretched out his hand in a gesture of invitation, and said, "Then please start your performance."
However, Swansey obviously had no intention of giving them a chance to continue talking nonsense, and shouted to Henry: "Henry, come here."
The professor called, and Henry immediately stood up and walked over, looking eager.
"Here, you have to use a dimensionless angular coefficient to express the ratio of the helicity cross section relative to the unpolarized cross section, and then do the calculation. Do you understand? Then you can discuss the O(αs) order."
After hearing the professor's words, Henry's eyes lit up after a brief thought, "Yes! I understand!"
After all, he has a doctorate from the Ecole Normale Supérieure in Paris, so Henry's abilities are certainly very good.
Svensey nodded, then glanced at Lin Xiao, and said with a smile: "If you still have any mathematical questions, it may be more convenient and faster to discuss it with Lin than to ask me."
Lin Xiao quickly waved his hand: "Professor Swensey, I'm just a little better at math, but I'm still not as good at physics as math, and my knowledge base isn't that great."
Svensey smiled and said: "Basic knowledge is just a few books, but it's not possible without mathematics."
"In the era of classical mechanics, we summarized mathematical formulas through visible laws of reality, such as Galileo's Leaning Tower of Pisa experiment and astronomers."
"Now, in the era of quantum mechanics, we can only first obtain the mathematical formula, and then through unremitting efforts, we can discover its physical meaning. Can you imagine that after Schrödinger created the Schrödinger equation, he did not even know this equation
Does it have any physical significance? It was not until Born proposed the probability theory that people got a definite answer, and this accidental equation is also the basic equation in quantum mechanics."
"You are a well-known genius in the field of mathematics. Proving the twin prime conjecture and Goldbach's conjecture requires excellent inspiration. For a scholar, such inspiration can only be grasped once in a lifetime, but you can't
You caught it twice in just one year - oh, we have to count your success in the field of materials chemistry."
Swansey shook his head slightly and said with emotion: "So, you already have the title of 'Inspiration Hunter' in the eyes of many of us. Many friends are even looking forward to the day when you enter the world of physics. The world of physics
, I have been lacking a genius-like inspiration for a long time.”
Lin Xiao was stunned: "This...is there such a thing?"
Even before I get involved in the physics community, there is already a legend about me in the physics community?
Svensey smiled and said: "Don't underestimate yourself, believe in yourself."
"Moreover, in the past, many mathematicians later entered the field of physics research, such as Professor Qiu Chengtong, don't you want to give it a try?"
"In addition, I also read the article you published before about the relationship between energy storage function and medium propagation speed. Doesn't this prove that you are actually interested in physics?"
At this time, Henry next to him said: "Yes, Lin told me before that he is indeed interested in physics."
Svensey's eyes lit up: "Really? Lin, do you want to give it a try? I'll test you with a question. If you solve it, you can join my project in the future. How about it?"
Lin Xiao thought for a while, then nodded: "If you don't mind, of course I'll be happy."
Since he has nothing to do recently, he might as well experience high-energy physics, which he has long been interested in.
Svensey smiled slightly, then found a piece of paper from the side and wrote a question on it.
[Demonstrate the transmission of electromagnetic force and its process by photons from a mathematical point of view.]
Seeing this question, Henry and Lin Xiao both fell into thinking.
It is obviously not easy to demonstrate this problem from a mathematical perspective. Unless you have read relevant research by others, it also requires certain basic knowledge.
Seeing both of them thinking about it, Swansey smiled and said, "You can have a week to think about this problem. During this week, you can check out relevant books, such as quantum field theory, electrodynamics, etc.
Wait, you may find some answers in these books, but I hope to see some of your own innovative ideas."
"A week?" Henry couldn't help but said: "You still need to have your own innovative ideas? Teacher, isn't this time too short?"
But at this moment, Lin Xiao next to him suddenly said: "Can I use a pen?"
Henry's eyes widened: "No! You can't..."
There was a little surprise in Svensey's eyes, and then he handed over the pen in his hand with a smile.
Lin Xiao took the pen handed over by Swen Sai and continued to write on the paper.
"Let's first use the electromagnetic field motion equation in electrodynamics..."
【∫fdv=∮T·dS-dG/dt】
"Now let's discuss the transmission under electrostatic force. At this time, dG/dt is equal to 0..."
As Lin Xiao slowly wrote down, a series of complex formulas were born in his hands.
Although he is required to discuss this issue from a mathematical perspective, it is obvious that he also needs to use various formulas in physics.
Various inferences in physics are derived based on existing physical formulas and cannot be made out of nothing.
Of course, the mathematical methods Lin Xiao used in it also amazed the two people next to him.
The admiration in Swensey's eyes grew more and more. Looking at Lin Xiao's solid foundation of basic knowledge, one could tell that this young man had probably been focusing on physics for a long time.
And he was praised for his wonderful mathematical ability.
This is the genius that physics needs most today!
After Schrödinger derived the Schrödinger equation, Einstein sincerely praised him: the inspiration for this work came from a true genius like spring water.
He was already looking forward to what kind of abilities Lin Xiao would show in future projects.
As for Henry next to him, he was already stunned.
Watching Lin Xiao write more and more in-depth mathematical formulas, he was thinking at this time——
Didn’t you just say that you are not as good at physics as mathematics?
But when he thought about it, he just wanted to hold his forehead, and there seemed to be nothing wrong with this sentence.
