When Li Zheng was obsessed with solving problems.

He didn't know that Jiang Qinghua had been scratching his head crazily for a long time.

Sun? Nuclear fusion? Nuclear reaction equation?

Jiang Qinghua is in chaos.

The more chaotic it is, the more confused you will be by the scary questions.

The more chaotic it is, the harder it is to find simple and pure ideas for solving problems.

After being confused for an unknown amount of time, Jiang Qinghua aimed at the second question.

This is a classic question about hitting a ball with a stick and calculating kinetic energy and speed.

This is good, there are routines.

Just apply the formulas of conservation of kinetic energy and momentum.

However, he was wrong.

He didn't know that in the physics competition.

The more scary the question is, the simpler it is actually.

The more mentally handicapped things like small balls and poles are, the more difficult it is.

For example, things like artificial satellite orbits and solar nuclear reactions. Although the questions are very grand, they only test your application ability. As long as you string together the physical environment and simple knowledge, you can always give the answer easily.

.

On the contrary, these devilish things like balls and rods will assess you in a terrifyingly detailed way.

Where does the ball hit the club?

What kind of twisting occurs in the rod?

After twisting to the extreme, how will it shake back?

What state will it end up in?

By the way, there are also small balls tied to both ends of this pole.

This complicated situation can be analyzed step by step using calculus, and it is basically a foregone conclusion.

Jiang Qinghua undoubtedly fell deeper and deeper in this process.

He began to doubt himself deeply.

Why, after studying for so long, can’t you even figure out a mentally retarded question like a small ball and a thin rod?

In the pain, Jiang Qinghua's stomach growled unsatisfactorily, and she couldn't bear it anymore.

In fact, this question has really been difficult for Li Zheng for a long time, much longer than solar nuclear fusion.

Just because the calculation steps are too complicated, it is much more difficult than the math exam.

As for Lin Yujing...

She used a unique method of angular velocity and angular momentum to solve the problem, completely bypassing process analysis and derivation calculations, and had already started working on the third problem.

These three situations also fully reflect the styles of the three people.

Li Zheng:a→b→c→c……→c

Lin Yujing:a→(strange train of thought)→z

Jiang Qinghua:a→?→b→?→a?→c?→……→???

…

The war inside the office is fierce, but outside the office it is very leisurely.

On her way back from fetching water, Tao Feifei happened to bump into Yu Hong who was returning from an interview.

Although they didn't have much interaction on weekdays, facing the competition and facing the question of how to train Li Zheng and Lin Yujing, Yu Hong became extremely enthusiastic and pulled Tao Feifei away and refused to let them go.

"Xiao Tao, please don't underestimate Li Zheng."

"The speed of this person's progress is terrifying."

"And he has made progress in all aspects, without any blind spots in knowledge."

"Shi Yang, who beat Li Zheng by a few points in the end, is a chemical genius who has been in the chemistry laboratory since he was a child. He is a once-in-a-lifetime genius."

"In the end, Li Zheng's theoretical score is still higher than him? If it weren't for the limited experimental opportunities, it's hard to tell the result."

"Just listen to me and just give Li Zhengshu the highest goal and move forward."

Tao Feifei nodded repeatedly after hearing this, but she was also a little disapproving.

In her eyes, the gap between chemistry competitions and physics competitions is roughly equivalent to the gap between the Asian Games and the Olympic Games.

The core of the difference is that chemistry has a lot of hard-to-learn knowledge points, while physics requires more talent.

This leads to the fact that those real monsters have no energy or interest to invest in chemistry competitions. Only physics competitions can provide a stage for them to display their talents.

The core reason why Li Zheng Huajing achieved such terrifying results was his own terrifying study intensity.

When it comes to thinking talent, he is certainly not bad either.

However, what he is about to face is a large group of Lin Yujing level monsters.

Of course, Tao Feifei is not good at confronting Yu Hong, and at most she only dares to be weird.

"Teacher Yu, let me ask you something." Tao Feifei rubbed the kettle and asked slowly, "Look, in the preliminary round of chemical competition, Li Zheng and Lin Yujing were ranked second and seventh. They were probably far behind.

Five points, right?”

"Yes, I didn't expect Li Zheng to be higher." Yu Hong nodded repeatedly, "You have to know that Shi Yang was five points higher than Li Zheng at that time. In just one month, Li Zheng's national finals results were completed.

Go ahead."

"Yes, yes, yes...but I want to ask..." Tao Feifei pursed her lips and said, "Taking the preliminary round of Huajing as the time point, if Li Zheng's energy invested in learning Huajing is 100, then how much is Lin Yujing's approximate number?

"

"..." Yu Hong's eyebrows tightened. After thinking for a long time, he raised his hand and made a 2 sign.

"20?" Tao Feifei asked.

"2."

"..."

"..."

The two fell into a long silence.

"Actually, this 2, I've already said is more conservative... I feel like she plays basketball more attentively." Yu Hong shook his head and sighed, "I can't help it, I have never seen Lin Yujing at this level in my life."

"When you say that, I have higher expectations for Lin Yujing..." Tao Feifei took a breath and said, "You have to know that in the face of the physics competition, Lin Yujing's investment... is 100

.”

"Oh my god..." Yu Hong opened his mouth in shock, "Then...can you still teach me?"

"Hey!" Tao Feifei slapped her thigh in pain, "It's too difficult. She occasionally has questions... I don't even understand what she's asking... I even suspect that I am a fake graduate student..."

"Fortunately, she didn't ask me any chemistry questions." Yu Hong pouted at the office after the disaster, "What are they doing now?"

"Doing the semi-final questions is equivalent to the preliminary round of your competition." Tao Feifei whispered, "The two of them are competing very well."

"It's normal. Chemistry also occasionally competes." Yu Hong suddenly became excited, "Is this a real question? Do you know the score line?"

"I know all the real questions." Tao Feifei shook her head and said, "But I can probably guess the result."

"Haha." Yu Hong narrowed his eyes and patted Tao Feifei gently, "You are still too young."

"..."

"Come and talk to me after the results are out."

"Teacher Yu, who is too late, this set of questions must be done after 7pm..."

"It's okay, I'll wait for you." Yu Hong took out his phone and swallowed, "It's been a long time since I had barbecue."

"..." Tao Feifei realized that Yu Hong was going to eat something terrible at school again.

At this time, Yu Hong was already fiddling with his mobile phone and walking away: "Then I'll order a meal for 6 people. At least there are two big boys."

"You... spent money..."

…

Tao Feifei entered the office and saw the three of them working hard to solve problems. She didn't want to peep.

But I couldn't help it.

As a physics teacher, she is very confident in her judgment.

This kind of confidence is not something that comes naturally, but is honed through repeated comparisons of predictions and results.

Li Zheng 35, Jiang Qinghua 14, Lin Yujing 75.
