A sea of stars for top students

[What you need to learn]

After writing this line, Bi Wanqing continued: After all, this is a physics competition, and you will not be required to understand the entire advanced mathematics book. For example, there is no need to read the mean value theorem. These are the things you need to master.

After Bi Wanqing finished speaking, he picked up the chalk and started writing on the blackboard.

[Derivative] [Differential] [Definite integral] [Indefinite integral] [Solving differential equations] [Taylor expansion]

After writing, Wan Qing circled the word integral of definite integral, In terms of integrals, what you need to focus on mastering are various forms of substitution and trigonometric function integrals. This can be said to be the most important part. You Most of the logarithmic integrals encountered in calculations need to be converted into trigonometric functions and then integrated.

Wu Bin, who was listening below, nodded, secretly glad that he had conquered the fierce horse of trigonometric function a while ago.

After you have learned solidly, what I want to teach you is the specific application of calculus in physics problems. The first point is that you must be able to formulate differential equations for specific problems. At this point, you have to answer a lot of questions. I will prepare the questions for you.

Approximately how many types of questions can be answered!? Wu Bin almost stood up excitedly after hearing Bi Wanqing's words.

In response to Wu Bin's reaction, Bi Wanqing would smile kindly every time, and then say: Don't worry, there are a lot of them.

It would be great!

In addition, Taylor expansion is mainly used for small-volume analysis. Sometimes the commonly used first-order small-volume expansion is not enough, so Taylor expansion to second-order calculations must be used...

After that, Bi Wanqing spent almost an hour explaining to Wu Bin the framework and general content that he needed to learn.

Seeing that Wu Bin showed no fear or boredom at all, Bi Wanqing stepped down from the podium and said to him with a smile: Although most people want to achieve results in the semi-finals or even the preliminaries, they have to start special competition training from the first year of high school. .”

But every era has never lacked outstanding masters. I once had a professor who entered high school at the age of 8, began to audit university courses at the age of 9, and then participated in the International Physics Program at the age of 10, 11, and 12. Olympic Games and won bronze, silver and gold medals respectively.”

Wu Bin couldn't help but open his mouth after hearing this. He now doubted not only whether the professor also had a system, but also whether the system in his mind was more advanced than his own.

Seeing Wu Bin's dumbfounded look, Bi Wanqing laughed twice, If you can pass the semi-finals and advance to the national championships, worst case scenario, you can also witness with your own eyes the wonderful scenes of Peking University and Jinghua University competing for the national first-class players.

What is the national competition... like? Wu Bin couldn't help but think about it.

National competition~ Bi Wanqing smoothed his thinning hair and said with a recalling expression: A few with particularly good results in the semi-finals will form a team to face other provincial teams. Those who can reach this point are the best in the country. There are about a hundred people, all of whom have unique skills, among which the students from Lianghu are the strongest, and there are always people from them representing the country to participate in IPhO every year.

'Are you going to compete with the best in the world...'

Thinking of this, Wu Bin couldn't help but get excited.

Looking at Wu Bin's eyes full of fighting spirit, Bi Wanqing seemed to have recalled something and said, You remind me of something my professor said to me before.

What words?

He said, when it comes to competitions, if you like it, go for it. If you don't like it, go do something else.

It seems... quite philosophical?

Actually, it was just a casual remark from his old man. Later he told me a story about his childhood. He liked to dismantle things since he was a child, including old radios, alarm clocks, watches, and game consoles.

This...isn't this just a naughty kid?

But they can still put it back together after dismantling it.

Boss, boss, teacher, please continue.

Later he told me that the electric current is edible. 10v is sweet, 50v is salty, 100v is spicy, and 150v means the tongue can't feel it. As for 220v...you can try it.

Wu Bin broke into a cold sweat after hearing this and wiped his forehead with his hand, I feel that I am quite happy to be alive.

I couldn't help but sigh in my heart: 'Yao Shou, this naughty kid with high IQ really knows how to play. ’

Looking at Wu Bin's appearance, Bi Wanqing laughed loudly, patted Wu Bin on the shoulder and said, Interest has always been one of the most important parts of learning, and your interest in physics is even worse than mine, so anything is possible. , come on.

How is that possible? Teacher, if you are not interested enough in physics, why would you work overtime to teach me?

Hahaha, you saw it. Bi Wanqing laughed a few times, then suddenly sighed, If every student was like you, there wouldn't be any calls to reduce the burden.

Teacher, you seem to be particularly concerned about reducing your burden. Wu Bin asked.

Having gone through that era when all gold medals were available, look at it now, can you not care about it? Bi Wanqing sighed again after finishing speaking.

Speaking of competitions and gold medals, Wu Bin suddenly had an idea.

If one day e-sports can promote the development of the world and become mainstream, everyone will be proud of e-sports, play games every day and train until they are exhausted, and then parents will start crying.

It's so hard for my children to play games, playing until five or six in the morning every day.

Isn't that right? I practiced last-ditch for eight hours yesterday, and my eyes are all blurry.

This is nothing to you, my child's waist has been injured from practicing!

Then the Education Bureau could not withstand the pressure and began to reduce the burden on children. It did not allow schools to recruit students based on Internet cafe league champions and SOLO competition champions. It was strictly forbidden for all types of schools to set up key mid laner classes, key shooter classes, etc. under any name.

Then our country went from being able to win consecutive championships to being unable to even make it into the qualifiers.

Then I guess the people will not just sigh like Bi Wanqing. I am afraid that the Education Bureau will demolish it for you.

After all, it’s just math and physics competitions that are too high-end. Only a small number of people can enjoy the fun. Most people can’t even understand it, but those who like to watch it and those who can understand it can look at their own country. Can you not be angry that your strengths are weakening day by day?

Seeing that Wu Bin was in a daze, Bi Wanqing said: And do you think reducing the burden is really as simple as it seems on the surface?

I fell asleep yesterday... will update today!
