"Senior ...... Is there anything strange about it? ”

Looking at several surprised eyes, Wu Bin asked strangely.

After listening to this, Li Yan replied: "It's not that it's strange, it's mainly that most of the people in this lobby have entered the semifinals in the second year of high school, and the first year of high school will come in, no, that Cui Shaodong is the first in the world." ”

"Hey, hey, hey, I seem to hear my name, what bad things do you say about me." Cui Shaodong shouted towards Li Yan after hearing it.

"How dare you say bad things, Cui Shaodong is the best in the world!"

"Yes, yes, Cui Shaodong is the best in the world!"

……

After a wave of rhythm, Cui Shaodong naturally replied, "Li Yan is the first in the world." "I continued to intersect with other people.

"So it's rare to see a junior like me, right?" Wu Bin pointed to himself.

At this time, a chubby boy next to him said, "That's quite rare, hiss...... Speaking of which, Kasumi is in his third year of high school...... It feels like you're all over the dark horse keyword. ”

In the self-introduction just now, Wu Bin knew that this boy was from the second high school attached to the Normal University, and his name was Lin Luo.

After listening to this, Li Yan immediately showed a look of sudden realization and said, "It makes sense! Bow down first, Wu Shen is awesome! ”

"Don't don't, don't, I don't have a few key bosses in the city, you are awesome, you are awesome." Wu Bin said as he bowed his hand.

"Hahaha, you learn fast." Li Yan laughed.

After a few more idle words, Li Yan didn't stare at Wu Bin and asked, but chatted with those friends who were originally more familiar.

"Damn, have you brushed all this book? Big guy! ”

"Awesome, have you solved that problem? Giant! ”

"This rematch must be your first, Superman!"

“……”

Wu Bin, who really couldn't fit into this "membrane circle", shook his head and casually found a place to sit down.

At 8:50, there were a total of 14 students in the lobby at this moment, including Wu Bin, who should have been killed from the preliminaries.

'What a thousand troops crossing the single-plank bridge......

When Wu Bin finished sighing in his heart, several middle-aged people who looked like big guys walked onto the podium.

"That's the director of our city's competition committee." Looking at Wu Bin's inexplicable look, Li Yan whispered to him to popularize science.

"Oh~ Xie Li Shen."

The next thing is to listen to some chicken soup and the rules of the competition, and I have to say that the leader is the leader, and it is not good to be punctual, and the time came to 9 o'clock after the speech, and the exam officially began!

"Come on~"

"So are you."

After waving their fists with Li Yan, all the candidates began their journey in the semi-finals.

First of all, there are two experimental questions, one is the observation of the spectrum, and the other is the measurement of the magnetic field with the Hall effect, both of which are available in the "Experimental Instruction".

Wu Bin, who is a "ghost talent" in the experimental question, is naturally easy and smooth, so that the invigilators can't help but nod secretly.

'40 points should be stable. ’

After completing the experimental questions, Wu Bin has to face the legendary eight problems that as long as he does four things correctly, he can enter the top 50 in the province.

After taking a deep breath, Wu Bin began to review the question.

First of all, there is a big question in thermo-optical and modern physics, and the thermal test is a classic question type, heat uniformity, gas work and P-V image questions, but this time the classic is not the kind of classic that has to be taken once in any exam, but the classic in the problem, or even the classic in the classic.

'It's hard enough......

Wu Bin scratched his head, and then went down the trial.

"the chicken...... I even took the geometric optics test. ”

Wu Bin almost spurted out a mouthful of old blood, this is definitely one of the most rare types of questions in optics, Wu Bin felt that his hand holding the pen was trembling slightly.

'Old licker...... Here's a call. ’

It seems that God really heard Wu Bin's prayer, and then gave Wu Bin two electrical questions.

One test is electromagnetic induction, and what is required is to induce electromotive force, which made Wu Bin almost shed tears of excitement.

I'm good at it! ’

As long as you understand the question and then follow the idea of the question, it is easy to get full marks for this kind of question, and you will not use too advanced knowledge.

'Using Faraday's law of electromagnetic induction should work. ’

Another problem is the design scheme of the cyclotron, the magnetic field is definitely not able to escape, and the classical charged particles are rotated in the electric field by the Lorentz force.

At first glance, Wu Bin felt that he still had some ideas in the first question, but the second and third questions were really difficult.

'How does the speed change on each lap...... How does the radius change, alas, a headache. ’

But it's a little easier than the two questions above. ’

After turning the pen and relieving the pressure, Wu Bin continued to look down.

I have an MMP that I really have to say! ’

The essence of modern physics is the atomic structure, energy level and transition, and even more disgusting things even bring a one-dimensional positive touch!

I think the person who asked me is embarrassing me, a little boy! ’

'What about the special theory of relativity!?' Lao Tzu has been studying for so long, you bring me this!? ’

I have to say that Wu Bin's mentality has collapsed a little, and he is definitely wearing a white suit to cross level 10 and go head-to-head boss now.

If you don't get some bells and whistles, I'm afraid you won't be able to pass this level." ’

Thinking of this, Wu Bin raised his head and looked around, and was relieved to find that many comrades were also scratching their ears and cheeks.

After reading the question, Wu Bin understood that the focus must be to find the conserved quantity to eliminate other variables, and he also understood that there are many thieves in this kind of problem.

For example, one is a column and the other is a cylinder, and the distance from the column axis to the cylinder axis is R-r and the like.

Then there is a question about the trajectory of a star around the sun that can be hit almost everywhere you go, and the content of the test is barely decent, mainly to examine the students' calculations related to conic curves.

'Whew...... Mechanics questions are awesome! ’

Although he has always known that mechanics questions have always been the first difficulty, Wu Bin still knelt after reading the finale, and both knees were broken together.

The topic is a test of trucks, which sounds a little more simple than the kind of satellites, solar systems, and hundreds of refractions of light.

But in fact, it is precisely this kind of question that looks ordinary and unremarkable, which is the most disgusting!

First of all, the multi-body friction topic is what Wu Bin has always found very tricky, and this kind of problem is very large to calculate, and even if it is big, it is not pleasant to calculate, and it is easy to lack conditions.

"Hoo ......"

Wu Bin, who had finished reviewing all the questions, took a deep breath and opened the Casio calculator.

'Gan Lingliang! ’

In the silent roar, Wu Bin picked up the pen and began to do the question.
