Xueba's Sea of ​​Stars

Chapter 91 Four Emperors
In the top 3 of the 8 grades in class 105, there is no Pei Jiamin, because she has a huge shortcoming, which is English. This time, she even only got [-] in the senior high school entrance examination, which can be regarded as pulling off her trouser legs. .

"Ah~"

Seeing Wu Bin and the others walk out of the classroom, Pei Jiamin sighed with some discomfort.

Recalling what Wu Bin said to her, "It's useless to memorize words in English", I took out the notebook he lent me and started to read it.

Learning to learn, Pei Jiamin suddenly smiled sweetly again, 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 herself, and every time it ended, she would smile at her Say, "If you have any questions next time, you are welcome to discuss with him."

'And his handwriting seems to be getting better and better. '

Pei Jiamin, who was flipping through the notebook, had bright eyes.

……

On the third day after the photos were taken, the Honor Roll was officially updated, and many students who were eating melons rushed to watch.

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

"A nonsense inspirational story...that's a fairy tale, okay? In the third and third year of high school, I rushed from the bottom to the top. What kind of IQ does this have? It's too shocking."

"It's really good, but our teacher has always emphasized to us that he is working hard, saying that whenever he has free time, he will read books.

"Do you believe what the teacher said? It's impossible for the teacher to tell you that people can read the book once, understand the questions after doing the questions once, and work hard to be the first in the grade? I'm no longer a primary school student, so I don't believe it."

"Why can't it work? I've seen a lot of masters who brush questions."

"Is there anyone who got to the first place?"

……

While the boys crowded in the front were discussing whether Wu Bin rushed to the first place through hard work, the girls standing in the back row were whispering to the photos.

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

"Well, this one is really good, do you think his face looks a bit like Daniel Wu?"

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

……

The girls' discussions were quickly heard by the boys around them. For a while, they didn't continue to discuss Wu Bin's enthusiasm for being a top student. An atmosphere called despair spread among them very quickly. .

"It doesn't matter if you are good at studying, and you are so handsome, and let the scumbags live..."

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

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

When the girls were all confused, a boy immediately jumped out and volunteered to explain: "A game term, it almost means that among all the students in Xiazhong, Wu Bin is the strongest, he is really arrogant. "

"But they do have arrogant capital."

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

"Tch, I'm still taking the number one Raven in Xiafu, what's the use of just taking the exam, can you catch my lightspeed 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! Who loves whose grandson!"

"Go, go over the wall!"

^…

"Ah!"

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

"What's the matter? Have a cold? It's almost the competition time. You have to pay attention to your body. Why don't you go back to rest early today." Hearing Wu Bin sneeze, Bi Wanqing asked with concern.

"It's okay, teacher. I'm in good health. Don't worry." Wu Bin wiped his nose, indicating that he was fine.

"Don't be brave, don't get sick during the competition, it will be useless to learn more."

"Don't worry, teacher, I know what's in my heart, you can continue." Wu Bin suddenly wanted to sneeze again, but after shrugging his nose twice, the sneeze disappeared.

'It's so annoying, and who is talking behind my back that I'm handsome. ' Wu Bin rubbed his nose and thought.

On the podium, Bi Wanqing saw that Wu Bin did not seem to have any other signs of a cold, so he continued to write the last line on the blackboard mountain.

【Theoretical Mechanics】【Electrodynamics】【Thermodynamics】【Quantum Mechanics】

"Okay, today we will continue to study the four major mechanics." Bi Wanqing tapped the chalk and began to talk.

When Bi Wanqing mentioned the four major mechanics for the first time, he called them the four most important courses for the introduction to physics.

Wu Bin was stunned when he heard it. If these four old brothers are just beginners, then what did he learn before?Is it preschool?

It was only later that Wu Bin found out that these four old brothers are all compulsory courses in the physics department of the university, and each of them belongs to the existence of refreshing your worldview.

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

If all the rankings are based on refreshing the three views, quantum mechanics is definitely ranked first.

As for why these four courses sound like they are very stupid, as if the four courses of mechanics [Four Emperors] are called introductory courses, it is entirely because the contents of these four courses constitute the most basic theoretical system of physics so far. s frame.

Think about it, you haven't put up the frame, where is the space for you to put things in it.

However, as far as Wu Bin's current knowledge is concerned, it is mainly for the exam.

Take theoretical mechanics as an example. After contacting theoretical mechanics, Wu Bin discovered that besides Newtonian mechanics, there are Lagrangian mechanics and Hamiltonian mechanics in the world.

According to Bi Wanqing's words, if you want to take the national one, basically you only need to know how to write Lagrangian equations. Simple equations of motion can be solved similar to those in high school, and even more complicated ones will not appear in the exam.

As for the Hamiltonian equation, you just need to know it. You won’t be able to take the test, but you need to be familiar with the derivation process. Sometimes it will save you a lot of tedious calculations. Looking down, many problems are not problems.

Here, Bi Wanqing mentioned by the way that if Wu Bin has the opportunity to enter the training team, the knowledge he needs to learn will of course be deeper, and he will need to remember two sentences at that time.

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

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 mean anomaly angle, deviating anomaly angle, and true inflection angle of celestial body motion.

Finally, Bi Wanqing said with a smile: "Learn these, when you do analytic geometry, there will be a mysterious bonus."

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