Scholar’s Starry Sea

There is no silhouette of Pei Jiamin in the first fifty li of the eighth grade in Class 3, because she has a huge shortcoming, that is, English. This high school entrance exam even only took 105, which is considered Pulled off the trouser legs of her total score.

"Oh~"

After watching Wu Bin and they walked out of the classroom, Pei Jiamin was a little uncomfortable sighed.

Remembering the phrase Wu Bin said to her, "English words are useless", so he took out the notebook he lent him and read it.

Learning and learning, Pei Jiamin suddenly laughed sweetly again, because she remembered that no matter how many people gathered around Wu Bin during the lunch break, as long as she passed, Wu Bin would always give priority to teaching herself. And every time at the end, he smiled and said to her, "Is there any questions next time, welcome to discuss with him."

'And his words seem to be getting better and better. '

Pei Jiamin, who flipped his notebook, had bright eyes.

……

On the 3rd day after the photo was taken, the honor roll was officially updated, and many students who were eating melon rushed to watch.

"This is the Wu Bin. Our teachers have used him to tell us inspirational stories for a month."

"A nonsense inspirational story...that's a mythical story. Okay, I rushed from the bottom to the top in the third three months of high school. What an IQ, it’s too shocking."

"It's really amazing, but our teacher has always emphasized to us that he is working hard. It is said that as long as you have free time, you can read a book.

"Do you believe the teacher? Teacher is impossible and you said that people will read the book once and read it, and they will understand after doing the questions, and they will be able to reach the first grade with hard work. I'm not a primary school student anymore, I don't believe it. "

"Why don't it work, I see a lot of bookworms. "

"Have you gotten to the top? "

...

While a few boys squeezed in front were discussing whether Wu Bin was trying hard to get to the top, the girls standing in the back were right. Whispering with the photo.

"It's rare that there are handsome guys on the list. "

"Well, this is really good, don't you think his face is a bit like Wu Yanzu. "

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

……

The discussion of the girls was quickly heard by the boys around. For a while, they did not continue to discuss what type of Bookworm Wu Bin is. Now, an atmosphere called despair spreads among them very quickly.

'It doesn’t matter if you are a good student, if you are so handsome, you will not let the scumbag live...'

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

"Xia... suit, first? I don't know much about it. "

When the girls were all lost, a boy immediately jumped out and explained courageously: "A game term, which almost means that among all the students in Xiazhong, Wu Bin is the strongest. Yes, it's really arrogant. "

"But people do have arrogant capital. "

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

"che, I'm still Xiafu First Raven, what's the use of the test, can I take the QA at the speed of light? "

"Oh, this B is pretending to be for you. It's so sour. Come on, I'm Xiafu's first weapon to play with you. Father and son game, dare you? "

"OK! Who counsels grandson! "

"Go, go over the wall! "

^……

"Aye! "

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

"Why?" Have a cold? This is almost the game, you have to pay attention to your body, or you should go back to rest early today. "Hearing Wu Bin sneezing, Bi Wanqing quickly asked with concern.

"It's okay, teacher, I'm in good health, don't worry. "Wu Bin wiped his nose and said that he was okay.

"Don't be aggressive. Don't get sick during the game. It's useless to learn more." "

"Don't worry, teacher, I know it in my heart, you go on. "Wu Bin said that he wanted to sneeze again, but after the nose shrugged twice, the sneeze disappeared.

'It's so annoying, who is talking about me behind the scenes that I am handsome.' Wu Bin touched I touched my nose and thought.

On the podium, Bi Wanqing looked at Wu Bin as if there were indeed no other signs of a cold, so he continued to write the last line of words on Chalkboard Mountain.

【Theoretical Mechanics】 [Electrodynamics] [Thermodynamics] [Quantum Mechanics]

"Well, today we will continue to learn the four major mechanics. "Bi Wanqing knocked on the chalk and began to talk.

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

Wu Bin who listened to me was astonished at the time. If these four Old Brothers were just a beginner, what did he learn before? Preschool?

Later Wu Bin learned that these four Old Brothers They are all compulsory courses in the Physics department of the university, and they belong to each being to refresh your world view.

To summarize briefly, theoretical mechanics discards the concept of force and replaces it with the smallest amount of action, electric Mechanics discards absolute time and absolute space and introduces the concept of field. Statistical mechanics looks at the world from the point of view of probability. Quantum mechanics is more ruthless, which directly means that the world is described by algebra rather than analysis.

If you refresh the rankings with three degrees of view, Quantum mechanics is definitely ranked first.

As for why these four sound content is very awkward, as if the mechanics [Four Emperors] The four courses are called introductory because the content of these four courses constitutes the most basic framework of the theoretical system of Physics so far.

Think about it, you didn’t put up the framework, where is it? The space for you to put things inside.

However, as far as the knowledge Wu Bin is exposed to, it is mainly to deal with exams.

Take theoretical mechanics as an example, contact theory After the mechanics, Wu Bin discovered that in addition to Newton mechanics, there are Lagrangian mechanics and Hamiltonian mechanics in the world.

According to Bi Wanqing's words, if you want to take Guoyi, you basically just need It’s enough to write Lagrangian equations. Simple equations of motion can be solved similarly to high school content. No matter how complex they are, they won’t appear in the exam.

As for the Hamiltonian equation, it’s even more so. 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, that is, the so-called standing high and looking low, there are many problems. , It’s not a problem.

Here, Bi Wanqing, by the way, if Wu Bin has the opportunity to enter the training team, then the knowledge that needs to be learned will of course be deeper. When the time comes, you need to remember two sentences.

The Lagrangian equations derived from Newton’s second law are all hooligans, but it is indeed possible to derive the Hamiltonian equations from the Lagrangian equations.

That’s because of Lagrangian equations.

Grange mechanics and Hamiltonian mechanics are based on completely different foundations from Newton mechanics.

Today, Bi Wanqing gave Wu Bin the emphasis on Ke The pler equation, the mean anomaly angle, the partial anomaly angle and the true turning point angle of the motion of celestial bodies have all been understood, and it is very helpful to solve the problems of the stars and the sea.

In the end, Bi Wanqing also said with a smile: "Learn this, when you do analytical geometry, there will be a mysterious bonus."

Although Wu Bin did not understand this mysterious What is the bonus, but he still believes it!
