Chapter 230 (1/2)
Examinations are always relative.
The same paper, from the perspective of different people, has different feelings.
For example, Li Zheng, after doing the first two mechanics problems, the biggest feeling is that this is a ”calculus competition for middle school students”.
There is no way, because the mechanical problems are so classical that it is difficult to make any breakthrough in concept and thinking, so we have to do something in mathematics.
In Shi Yang's eyes, it is another world.
First of all, it has been 20 minutes since the exam began. He has not read it. There is no doubt that before it becomes a physics problem, it is first a reading comprehension problem.
Chinese less than 120 points, all out!
When Shi Yang got here, his eyes were dull and he died.
Only those who are careful in mind, have a dual discipline in Chinese and physics, and have excellent endurance. Even if the author is not segmented, and has no comma, can he be brave enough to read it.
And Li Zheng is such a person.
In about two hours, he hit the final question -
[lightning is one of the most magnificent natural landscapes on earth 】
(be ready to start ~)
[gamma ray bursts Lightning cloud discharge Small ice crystals Cloud to ground lightning]
(do you understand, brother? I don't know. Read it several times.)
Take advantage of Measurement of electric field in a cylindrical space lightning cloud 0.15MVm…… 】
[the radius is 2.5km, and the height is 1.0KM 】
[known vacuum dielectric constant ε = 】
(refueling, you can)
[in the process of electrification, the charge at both ends of the lightning cloud will increase exponentially with time 】
[when the surface electric field is greater than 1.0kvm, cloud to ground lightning will occur 】
[the lightning cloud moves down slowly from the high altitude until it 】
[try to estimate the surface electric field intensity directly below the lightning cloud. 】
(there is one saying, I really don't intend to let you understand. Even if you understand, it's just that you think you understand, but in fact you don't understand it. Even if you really understand, don't worry, you can't do it.)
Even Li Zheng was a bit broken when he read this.
The horror is, this is only 13 of the problem.
Li Zheng tried to scan the back five questions first.
He seems to see strange words like ”ball lightning”, ”ionosphere”, ”halo expansion” and ”microwave bubble”.
It's like reading hard core science fiction.
The problem is, in science fiction, there are usually scientists to do this without the reader's trouble.
And this time, I'm sorry, you're a scientist.
Don't you like physics? Isn't your ideal to create the future of mankind?
Come on, here's the calculator. Here you are.
Most people read this question, have a feeling of broken dreams.
Even Li Zheng, the hand holding the pen also can't help but tremble, repeatedly reading the topic, the sweat on his forehead is more and more.
Even if the physics score is close to 350.
He has done almost all the physics problems in the world.
But at this time, he had a kind of original ”top-level papers, usually need several people to work together for a month to master one or two.”
”This is the lack of learning ability and the gap between problem-solving machines and academic talents.”
”And this question tests this ability.”
”It can be said that this topic is a small paper, a primary school achievement.”
”Whoever can chew and understand clearly within the specified time will get the 70 points, and the one to be selected in the physics competition.”
”For this question, it is a test of your own thinking strength and understanding ability. No matter how much training you take, no matter how many famous teachers give advice, there will be no effect.”
”On the contrary, students who are self-taught have more advantages.”
Two teachers, a man and a woman, nodded repeatedly when they heard that. If it was true, they would accept the letter.
”It's Mr. Sun, who sees it better than us.”
”I almost forget that this kind of examination is to select academic talents.”
”Sun Xiubin” only raised his hand and laughed.
”Of course, this problem also has its problems.”
”It should have been in the finals.”
”I'm afraid the students will not be able to cope with this kind of question in the second round.”
His voice has just dropped.
Shi Yang raised his hand suddenly, his face full of anxiety.
Different from Li Zheng.
Every time he raises his hand, he really wants to do it.
In some ways, like Li Zheng and Lin Yujing, he seems to have returned to the original origin.The starting point where all the shit comes out.
……
At twelve o'clock sharp, the bell rings.
