Exams are always relative.

The same volume, from the perspective of different people, has a wide range of feelings.

For example, Li Zheng, after doing the first two mechanics problems, his biggest feeling is that this is a "calculus competition for middle school students".

This can't be helped, because the mechanics problem is too classic, and it is difficult to make any breakthroughs in concepts and thinking, so I have to do things in mathematics.

In Shi Yang's eyes, it was another world.

First of all, it has been 20 minutes since the test started, and he has not read the second question yet.

It's just that because of the first question "Teacups on the table", he really can't understand -

[What is the optimal height of the tea in the cup in order to keep as much tea as possible and stable enough?]

What the hell is this Nima asking?

What is as much as possible and remains stable enough?

Is physics so loosely worded?

Do you want to try chemistry to solve the problem?

Filled and then frozen into ice lumps?=+-?֏?

burst out of these wonderful ideas, which is actually no wonder Shi Yang.

The main thing is the grandson of the person who made the question.

In fact, this question asks "make the center of gravity of the teacup the lowest, and what is the height of the tea in the cup." 】

If he asks this, Shi Yang will probably still be able to score a few points.

However, if you use the description of "as much as possible and keep it stable enough", people who are not prepared enough for the competition are afraid that they will not be able to understand it.

So, more than 20 minutes later, Shi Yang had no choice but to look at the second villain cart question.

Haha, I will.

Shi Yang thought so in his heart.

He did quickly list a lot of mechanical formulas and was ready to show his strength.

But he soon became immersed in the force analysis and crash analysis of flatbed trucks.

It's like someone asks you, can you walk?

Of course you will.

Then the man turned into an old physics contest questioner, smiling and sending questions.

"Yes, yes, it will. ”

"Let your weight be M, your calf length will be L1, your thigh length will be L2, and your stride length will be L3......"

"Please calculate—"

"1: The maximum amount of stress on the knee and ankle joints with each step you take. ”

"2: The maximum angle between the two thighs for each step. ”

"3: Your left foot suddenly bent, causing the left foot to touch the ground and the pressure on it, are 1/5 of the normal state, in this case, please recalculate the first two questions. ”

If something like this happens on the street.

This old questioner should be beaten.

Unfortunately, this is the exam room.

And Shi Yang, even if he is the king of the competition, can only sigh in the face of such a situation.

At this time, of course, it was not only Shi Yang who was looking at it.

Even if they are old people, they will probably be at a loss in the face of this terrifying second question.

This kind of question, I feel that I am here to raise the bar, I think the paper is simple, and I must add a question that no one can solve.

And even if you can figure it out, it's enough to do it for half an hour.

Therefore, the second question that Li Zheng calculated with some effort has been sealed as an extreme problem in the eyes of most people, and after writing down a few formulas and ideas, he gave up directly and rushed to the third question.

This third question is very eye-catching at the beginning-

[A simplified model of an electromagnetic railgun is shown in Figure ......]

Seeing this, half of the people thought of "Sister Cannon", and the other half thought of "Bureau".

There are also those who think of both.

This part of the people, because they think too much and interfere with the exam ideas, usually die a miserable death.

If you carefully study this electromagnetic cannon, you will find that it is very similar to the 32nd semi-final questions, and for those who have thoroughly eaten the real questions in previous years, it is equivalent to giving away points.

If you haven't done it before, let's study the super electromagnetic cannon in a down-to-earth manner.

The fourth vibration question, the difficulty has decreased slightly, but it is a brand new question, there is no template, and it belongs to the kind of question that can be done with a solid foundation.

The fifth question, the optics question, is probably the easiest question in the whole volume.

But calculus is still required, and optics must be mathematical.

Anyone who can do it here will probably have some understanding.

Although physics and mathematics who is more dick is still debated.

But the person who asked the question had an unusually clear attitude:

Math is Dad, come home if you don't know calculus.

The sixth question, the theory of relativity, discusses the π mesons that fly in large quantities in cosmic rays.

Real veteran competition students, when they see this kind of thing, are not panicked at all.

According to experience, things that look particularly deep and mysterious are often very superficial, as long as they are understood, they are actually very good.

The villain cart is the most terrifying.

Finally, the seventh and last question.

Not to mention anything else, just seeing a score of 70 points is enough for people to eat a pot.

This set of theoretical papers, with a full score of only 320, accounts for nearly 1/4 of this question.

You have to do it seriously.

That being said, most people quickly lost their earnestness.

Because the question of this question occupies an entire side of the paper.

There are no segments, there are very few commas, and they are densely packed with words and symbols.

Not to mention the physics test, even if it is put in the language test, it can be regarded as a top-level reading question.

If you count carefully, you will find that this question has nearly 2,000 words in text alone.

It's longer than a chapter for some web writers.

There is no doubt that this question is first and foremost a reading comprehension question before it becomes a physics question.

Those with a score of less than 120 in Chinese will be out!

When Shi Yang did this, his eyes were already dull, and he was dying.

Only those who are thoughtful, dominate the dual subjects of language and physics, and have excellent endurance, even if the author is not segmented and can read it without a comma, can it be possible to spy on one or two.

And Li Zheng is such a person.

About two hours sharp, he struck the final question—

[Lightning is one of the most magnificent natural landscapes on earth......]

(Get ready, get started~)

Gamma ray burst ...... Lightning cloud discharge...... Small particles of ice crystals...... Cloud Lightning】

(Do you understand it, brother?, I don't know how many times to read it.) ）

【Use...... Measure the electric field in a cylindrical airspace lightning cloud...... 0.15MV/m......】

[The radius is 2.5km, the height is 1.0km.Find the potential difference between the upper and lower ends of the area, the total amount of positive charge, and the carrying.]

Total Electrical Energy ......】

[Known vacuum dielectric constant ε=......】

(Come on, you can)

[During the electrification process, the charge at the upper and lower ends of the lightning cloud will increase exponentially with time......]

[When the surface electric field is greater than 1.0kV/m, cloud-to-ground lightning ...... will occur]

[Thunder cloud slowly moves down from the high altitude until it ......]

[Try to estimate the strength of the surface electric field generated directly below this lightning cloud.] 】

(One thing to say, I really don't plan for you to understand here, even if you do, but it's just that you think you understand, but you don't understand, even if you really understand, don't worry, you can't do it.) ）

When I read this, even Li Zheng was a little broken.

The scary thing is that this is only 1/3 of this question.

Li Zheng tried to glance at the back 5 questions first.

He seemed to see strange words such as "ball lightning", "ionosphere", "halo expansion", and "microwave vacuole".

There is a feeling of watching hardcore sci-fi.

The problem is that in science fiction, there are usually scientists who do this, and the reader doesn't have to bother.

And this time, sorry, you're a scientist.

Aren't you awesome, don't you like physics, isn't your ideal to create the future of mankind?

Come on, the calculator is for you, here you go.

When most people read this question, they have a feeling of broken dreams.

It was Li Zheng, and the hand holding the pen couldn't help but tremble, and between reading the questions again and again, the sweat on his forehead became more and more.

Even though the physical score is already close to 350.

Even he has done almost all the physics problems in the world.

But at this time, he actually had a feeling that he was abused by the question for the first time.

It's the feeling of knowing every word, but not knowing what the title is talking about.

It's the kind of feeling that suddenly comes up with doubts about "who am I", "where am I", "what am I doing", "what did I say earlier?"

It's the kind of feeling that is crushed across dimensions, and can't even struggle with the strength to struggle.

Li Zheng has almost forgotten this feeling.

But at this point, it's back.

The feeling of being abused is back.

As the so-called -

When the question god returned, he found that the villain's cart was picked by Li Zheng.

With an order, 100,000 demons came!

For Li Zheng, the feeling at this time is like being pressed by Mount Tai.

Despair, powerlessness, collapse.

But.

Not dead yet.

Although he has been pressed to the surface, his waist is still straight.

Hold on, just go back.

Here it is, the exciting super puzzle is finally here!

Li Zheng felt every pore on his body open.

Demonic nature, his eyes swept out again.

The return of the questioning gods?

TM you have a lot to do!

you.

......

Another exam room.

Lin Yujing was also in a bitter battle.

There aren't many questions that can put her in a bitter battle.

That's a one.

is different from Li Zheng's positive toughness, she chose to rewrite the topic by herself.

Simplify paper-like descriptions into clear steps and condensed language.

Disassemble a super problem into a number of ordinary problems, and attack them separately.

But she soon discovered that she couldn't.

The surface cannot be condensed or disassembled.

There seems to be a lot of redundant descriptions in this question, but in the real core place, not a single word can be extracted, and it cannot be reduced to a simple question.

It's comprehension, and this question is a test of comprehension.

When an unfamiliar breakthrough paper is in front of you.

Can you understand, and how long will it take?

In other words, this question is simply on-site learning, and it is a test of learning ability.

Give you a new set of theoretical knowledge, learn on the spot, and solve problems on the spot.

Thinking of this step, Lin Yujing's pen stopped.

Like Li Zheng, she seems to have returned to square one.

It was when I was in the second grade of elementary school, and I was at a loss when I first saw high school functions.

It was when I was in the first grade of junior high school, and I was amazed when I first learned about the Schrödinger equation.

It was the summer vacation of my freshman year of high school, and I was shocked when I read the Nobel Prize in physics paper for the first time.

At this moment, she put away her arrogance.

Returned to the original one, the girl who thirsted for knowledge.

......

After about half an hour, Shi Yang finally began to read this question.

Unlike the previous two, his heart is surprisingly pure, with only a few words-

The question, I'm Nyima!

Undoubtedly, this is also the voice of most people, both men and women.

In the examination room, looking at the candidates whose faces are constantly switching like a roller coaster, the three invigilators are also very understanding.

They have also read the papers, so they naturally know the difficulty of the questions.

In the big year, hitting a problem is not a bad thing.

This rematch will inevitably open up a big gap, the top ones are sharper, and the ordinary ones are more ordinary.

A male teacher chuckled, "I can probably think of the scene when I handed in the papers." ”

"The two questions 2 and 7 are really difficult...... "The female teacher sighed, "The second question is a large amount of calculation, and it takes 20 minutes just to calculate it, and the seventh question is 20 minutes just to read it, and it is difficult to understand ......."

"The second question is really a bit boring. Teacher Sun Xiubin shook his head, "I'm afraid that everyone will have a high score, so I will increase the amount of calculations, and the level of the questioner is limited." ”

"Is there a level in the seventh question?" the male teacher also snorted, "Is it about Chinese or physics?"

"Yes, yes. The female teacher followed, "The whole page is a question, it's a waste of time." ”

"Sun Xiubin" raised his glasses and said calmly.

"I don't think so. ”

"The seventh question is a question that really tests the learning ability. ”

"As you know, there are many cases where there are no textbooks for graduate and doctoral studies. ”

"The latest published papers, the most obscure academic articles, are your textbooks. ”

"For top-level papers, it usually takes several people to work together for a month to master one or two. ”

"This is the lack of learning ability, the gap between the problem-solving machine and the academic strongman. ”

And this question is a test of this ability. ”

It can be said that this topic is a small paper, a small academic achievement. ”

"Whoever can get the 70 points within the specified time will be the one to be selected in the physics competition. ”

"For this question, it is completely a test of your own thinking strength and comprehension ability, no matter how much training you participate in, no matter how many famous teachers you give guidance, it will have no effect. ”

"On the contrary, it is the self-taught kind of student who has an advantage. ”

The two teachers, a man and a woman, nodded again and again when they heard this, and if it is true or false, they will believe it.

"It is worthy of Mr. Sun, who can see it deeper than us. ”

"I've almost forgotten that this kind of examination is for academic talent. ”

"Sun Xiubin" only raised his hand and smiled.

Of course, this question has its problems. ”

"It should be in the final. ”

"I am afraid that the students will not be able to withstand this kind of question in the semi-finals. ”

His voice had just fallen.

Shi Yang suddenly raised his hand, his face full of anxiety.

is different from Li Zheng.

Every time he raised his hand, he really wanted to do that.

In some ways, he, like Li Zheng and Lin Yujing, seems to have returned to the original point.

The origin where the came out when I was scared by the problem.

......

At 12 o'clock, the bell rang.

In the entire Jijing semi-final examination room, no one submitted the papers in advance.

It was Li Zheng, and he wrote the seventh question three minutes ago.

And there is no guarantee of a pair.

"Sun Xiubin" and others finished collecting the papers and announced the end of the exam.

Howls of grief and indignation echoed throughout the classroom.

"!"

"It was sad last year, why is TMD even more difficult today?"

"Question 7: What a B thing?"

"The third question of the electromagnetic cannon,I'm full of school cities.,My heart is messed up.。 ”

"The second question is perverted, right, has anyone solved it?"

"After three years of preparation, it's really a day trip......"

"It's over, it's over, it's all over......"

is different from the girls who fail in the test when they are competing.

The boy didn't cry.

Either scold or be in a daze.

Only Li Zheng, the long-haired monster, and Shi Yang watched the trio again and again, and they were relatively stable.

Shi Yang's stability is mainly due to the emptiness of his stomach and his lack of strength.

Secondly, he was originally here for a day trip, and there was no pressure or expectation.

He turned around, lay on his side on the table, and said to Li Zheng through the long-haired monster: "Cool, ...... Zheng"

Before Shi Yang finished speaking, he sat up again.

Judging from his appearance, he is a brother and absolutely cool.

I don't know when I took off my school uniform, and the sleeves of my shirt inside I couldn't wait to touch my shoulders.

My hair was all wet and wet, like I was playing a football game.

On his face, he also had an expression of being sucked dry.

"It's cool......" Li Zheng raised his arm, and his hands were trembling now, "This question is strong enough." ”

"......" Shi Yang swallowed and foamed, "I've done this for you...... It's really okay. Looking at it this way, I'm halfway through it, so I still have a chance to make a Dragon Ball, right?"

"Don't beep...... Li Zheng trembled and packed up his things, "I'm going to find Lin Yujing to have dinner and talk about it." ”

"Take a brother. Shi Yang rubbed his stomach and said, "My stomach is empty, and I have no combat effectiveness." ”

"Where is empty, go back to eat. Li Zheng scolded.

"Don't, brother, I really want to participate in the question, and I don't want to talk about you and other girls. ”

"Shut up!" Li Zheng turned his head and said, "Okay, now tell me the answers to the second and seventh questions, and if it's reliable, you'll be counted as one." ”

"Ha, you're right. Shi Yang laughed and said, "Lao Tzu basically didn't write a word of these two questions." ”

And the face said. Li Zheng waved his hand in disgust, "Go back and review the competition, not everyone can go to the right question, so I might as well make some clues for the seventh question." ”

"Question 7......" The hairy monster who had been watching the play in the middle suddenly remembered something, and said thoughtfully, "I remember that the volume of the helium balloon is measured ...... 380m3, right?"

Li Zheng's eyes were stunned: "Are you talking nonsense? My result is 1900m3." ”

"Hah......" the hairy monster rubbed the back of his head stupidly, "you should be wrong." ”

"???" Li Zheng's eyes widened.

Should I be wrong?

Young man, for so long.

Only, a man, would dare to speak to me like that.

Just as he was about to say something, the long-haired monster suddenly waved his fist: "I know, you should have miscalculated the density at 12 kilometers above the ground, could it be 1.53?"

Li Zheng's eyes could have been even bigger.

"It's really ......" the hairy monster shook his finger and laughed, "If you think about it, when you count the LN earlier, was it sloppy?"

Li Zheng was so shocked that he grabbed out the scratch paper and examined it.

Soon.

"Ah!!" Li Zheng hugged his head angrily, "Why are you so stupid!"

"Don't worry...... the hairy monster waved his hand to soothe, "Is it that when you count it here, that very fierce teacher just reminded you that there are still 10 minutes to wrap up, which disrupted your rhythm?"

"......" Li Zhengmu turned his head, his eyes could not be bigger.

This forced is obviously in a daze 80% of the time, and I haven't even mentioned it a few times......

Thinking of this, Li Zheng's brain tensed.

Don't...... This is mental arithmetic?!

This level of complexity...... So much calculus......

You can't necessarily be a champion in a number of competitions, right?

This, so young, looks like a junior high school student......

How is it possible to compete for the championship......

Thinking of this, Li Zheng's scalp gradually became numb, and he said word by word: "You...... Call...... Miscellaneous...... ......"

The hairy monster smiled and stretched out his right hand: "Return to the wind." Yes, it's that return, that see, and that wind. ”
