Chapter 91 Four Emperors

In the first fifty years of the 8th grade in Class 3, Pei Jiamin is not there because she has a huge shortcoming, that is English. This time she only scored 105 in the high school entrance examination, which is considered to have taken off her overall score. .

"Alas~"

After watching Wu Bin and the others walk out of the classroom, Pei Jiamin sighed uncomfortably.

Thinking of what Wu Bin said to her, "It's useless to just memorize English words," she took out the notebook he lent her and started reading through it.

Learning to learn, Pei Jiamin suddenly smiled sweetly because she remembered that no matter how many people gathered around Wu Bin during the lunch break, as long as she passed by, Wu Bin would always give priority to teaching her, and he would smile at her every time. He said, "If you have any questions next time, you are welcome to discuss it with him."

‘And his handwriting seems to be getting better and better. ’

Pei Jiamin was flipping through her notebook, her eyes bright.

…

On the third day after the photo was taken, the honor list was officially updated, and many students rushed to watch.

"This is Wu Bin. Our teacher has been telling us inspirational stories about him for a month."

"It's a nonsense inspirational story... That's a fairy tale, okay? I went from the bottom to the top in three months in my senior year of high school. What kind of IQ does this have to do? It's so shocking."

"It's true, but our teacher has always emphasized to us that he works very hard, saying that whenever he has free time, he just reads.

"Do you believe what the teacher says? It's impossible for the teacher to tell you that someone can read a book and understand it once, do a problem once and understand it, and work hard to reach the top of the grade? I'm not a primary school student anymore. I don't believe it."

"Why can't it work? I've seen too many top students who just answer questions."

"Has anyone reached first place?"

…

While several boys in the front were discussing whether Wu Bin had worked hard to reach the first place, the girls standing in the back row were whispering to the photos.

"It's rare to have a handsome guy on the list."

"Well, this is indeed good. Don't you think his face shape looks a bit like Daniel Wu?"

"Hey, when you put it like that, it seems a bit like it."

…

The girls' discussion was quickly heard by the boys around them. For a while, they stopped discussing what type of academic master Wu Bin was. An atmosphere called despair spread among them very quickly. .

'It doesn't matter if you are good at studying, and you are so handsome, why should you let a scumbag live...'

"Hey, but what does his motto mean?" a girl asked curiously.

"Xia... take it, number one? I don't quite understand."

When the girls were all confused, a boy immediately jumped out and volunteered to explain: "It's a game term, which basically means that among all the students in Xiazhong, Wu Bin is the strongest, which is really arrogant. "

"But they do have the capital to be arrogant."

"Ah!!! I really want to pretend like him!"

"Tch, I'm still the No. 1 Raven in the Xia server. What's the use of just knowing the exam? Can you handle my light speed QA!"

"Ouch, this B pretended to be for you, it's so annoying. Come on, come on, let me play with you as the number one weapon in the Xia server, a father-son game, do you dare?"

"OK! Whoever is a coward is a grandson!"

"Let's go over the wall!"

^……

"Ah sneeze!"

Wu Bin, who was sitting in the small classroom listening to Teacher Bi's lecture, suddenly sneezed twice.

"What? You have a cold? It's almost time for the competition. You have to pay attention to your health. Why don't you go back and rest early today." Bi Wanqing asked with concern when Wu Bin sneezed.

"It's okay, teacher, I'm fine. Don't worry." Wu Bin wiped his nose to express that he was fine.

"Don't be brave and don't get sick during the competition. No matter how much you learn, it will be useless."

"Don't worry, teacher, I know what's going on. You can go on." As he spoke, Wu Bin suddenly wanted to sneeze again, but after twitching his nose twice, the sneeze disappeared again.

‘It’s so annoying, who is talking about my handsomeness behind my back? ’ Wu Bin thought as he touched his nose.

On the podium, Bi Wanqing saw that Wu Bin seemed to have no other signs of a cold, so he continued to write the last line on Blackboard Mountain.

[Theoretical Mechanics] [Electrodynamics] [Thermodynamics] [Quantum Mechanics]

"Okay, today we will continue to study the four major mechanics." Bi Wanqing knocked on the chalk and began to speak.

When Bi Wanqing first mentioned these four mechanics, he called them the four most important courses for introductory physics.

Wu Bin was confused when he heard this. If these four brothers were considered beginners, then what did he learn before? Preschool?

Later, Wu Bin learned that these four brothers were all required courses in the physics department of the university, and each one of them was here to refresh your world view.

To sum up briefly, theoretical mechanics has thrown away the concept of force and replaced it with the minimum amount of action. Electrodynamics has thrown away the concept of absolute time and absolute space and introduced the concept of field. Statistical mechanics looks at the world from the perspective of probability. Quantum mechanics is even more ruthless and directly Indicates that the world is described algebraically rather than analytically.

If all are ranked based on the three perspectives of innovation, quantum mechanics is definitely ranked first.

As for why these four courses, which sound very cool in content, just like the Four Emperors of Mechanics, are called introductory, it is entirely because the content of these four courses constitutes the most basic theoretical system of physics so far. s frame.

Think about it, you haven’t even put up the frame, so where is the space for you to put things inside?

However, as far as the knowledge Wu Bin is currently exposed to, it is mainly to prepare for the exam.

Take theoretical mechanics as an example. After coming into contact with theoretical mechanics, Wu Bin discovered that in addition to Newtonian mechanics, there are also Lagrangian mechanics, Hamiltonian mechanics, etc. in the world.

According to Bi Wanqing, if you want to get into the national first grade, you basically only need to be able to write Lagrange equations. Solving simple equations of motion is similar to high school content, and no matter how complicated it is, it will not appear in the exam.

As for the Hamiltonian equation, you just need to know it. You won't be tested in the exam, but you need to be familiar with the derivation process. Sometimes it will save you a lot of tedious calculations, which is the so-called standing on the high ground. If you look down, many problems will no longer be problems.

Bi Wanqing would like to mention here, by the way, if Wu Bin has the opportunity to join the training team, then of course the knowledge he needs to learn will be deeper, and he will need to remember two sentences.

Those who derive the Lagrange equation from Newton's second law are all hooligans, but it is indeed possible to derive the Hamiltonian equation from the Lagrange equation.

That's because Lagrangian mechanics and Hamiltonian mechanics are based on completely different foundations than Newtonian mechanics.

Today, Bi Wanqing focused on Kepler's equations for Wu Bin. He learned about the periapsis angle, periapsis angle and true inflection angle of celestial body motion, which will be of great help in solving the problems of stars and seas.

In the end, Bi Wanqing said with a smile: "Learn these, and there will be mysterious bonuses when you do analytic geometry."

Although Wu Bin didn't understand what this mysterious bonus was, he still believed it!
