Xueba, I beg you to go and escort him quickly!

"..."

“最后利用以上我说过的那些式子，可以得到电荷量为：Q=I△t=R2B3/ro=800kmvBR2/R1ro（4r1+πro）。”

"If I'm not mistaken, the answer should be this?"

The voice fell.

Dean Nie had goose bumps all over his body.

Inside the car, it's very quiet!

It's been quiet for a long, long time...

finally--

"hiss……!!!"

Dean Nie's gasp broke the silence.

Dean Nie is driving now!

He looked at the service area 5 kilometers ahead!

Turn directly and head for the service area!

Xu Heng, "?"

Just arrived at the service area!

Just parked the car!

Xu Heng originally thought that Dean Nie was going to the bathroom.

Can--

He unbuckled his seat belt, turned around abruptly, staring at Xu Heng with a pair of big eyes.

"hiss……!!!"

Another long inhale.

Xu Heng could see that Dean Nie's body was shaking.

Xu Heng, "Dean Nie, why are you looking at me like that all of a sudden?"

Dean Nie's scalp was numb, and his tone of voice was very heavy.

"You know what to ask!"

He suddenly lowered his head, looked at the blank paper in Xu Heng's hand, and then raised his head to look at Xu Heng.

"Student Xu Heng, this question, you, you, you, you...! Can you call it a calculation? You are doing oral calculations!"

Xu Heng also looked at him, and then looked down at the paper.

"Dean, why are you so excited?"

Dean Nie, "!!!"

"Can you not be excited?! How did you solve this question?!"

He is the dean of Peking University's School of Physics!

He used to be admitted to the School of Physics of Peking University with the honor of provincial champion and perfect score in physics!

Later, he studied all the way, got a doctorate, and then served as the dean of the school.

For so many years, let alone him, even the most talented classmate he has ever met, is not as exaggerated as Xu Heng!

He was shocked!

Do not!

To be precise, he was frightened!

scared! ! !

"Student Xu Heng, you... hiss..."

Taking another deep breath, Dean Nie couldn't even speak properly. He bit the bullet and suppressed the excitement in his heart...

But I can't hold it down at all!

"Hiss...｀々!"

His body was still shaking.

Xu Heng was embarrassed, "I'm sorry, Dean, I'm used to it... I used to do the same way when I did the questions. Unless the questions are a bit difficult, I will write a little bit. Otherwise, if I can do the math, try not to get it. "

"After all, I'm lazy."

Dean Nie, "!!!"

lazy?

Obviously this is not the problem, okay?

!!!

Dean Nie froze, staring at Xu Heng.

Stare very hard!

He clenched his teeth!

The masseter muscles of the face are clearly visible.

Xu Heng, "Eh... Dean..."

Dean Nie was quite frightened.

He looked at Xu Heng and kept thinking about what Xu Heng said just now.

Therefore, Xu Heng has long been used to it!

hiss! ! !

What Xu Heng takes for granted is probably unmatched by high school students all over the country, even teachers, or Dean Nie, doctors, professors, and deans!

Originally, Dean Nie just wanted to see Xu Heng's level with his own eyes!

But it doesn't matter if you look at it!

He was so astonished that he couldn't bear it!

"Huhuhu..."

Dean Nie was short of breath.

Xu Heng, "Dean Nie, are you okay?"

Dean Nie, "Hiss... I'm fine! I'm fine! No wonder you can come up with the title so quickly!"

"If the brain of ordinary people is the number 1, then your Xu Heng's is 100, or even more!"

Xu Heng, "???"

ordinary people?

Dean Nie, just be an individual, you call yourself an ordinary person!

How many real ordinary people are there?

? 0.01?

???

Xu Heng, "So, Dean Nie, do you want to go to the toilet? Are you still hungry?"

This is the service area!

Xu Heng didn't believe that Dean Nie came to the service area just to turn his head to look at himself.

Dean Nie, "No! Let's go! Hiss... let me take a few minutes."

He was very excited, excited all over his body.

He had to calm down as soon as possible before he could drive.

Otherwise, the hand holding the steering wheel will not be steady!

If there is a slight deviation, something will happen.

"Huh...huh...huh..."

Dean Nie took a deep breath.

Keep breathing deeply.

He tried his best not to look at Xu Heng in the back seat.

Xu Heng, "..."

I'm afraid there is something wrong with the dean...

Suddenly, Xu Heng felt a little regretful.

It was more than ten minutes before the car returned to the high speed.

Dean Nie was still breathing heavily.

The way he drives at this moment is very similar to when he drove for the first time more than ten or twenty years ago.

tension!

Holding the steering wheel with both hands!

Xu Heng, "Well... Dean Nie, why don't we talk about other things! Don't talk about study problems, tell me about the institute!"

Xu Heng is helping Dean Nie to divert his attention.

"Huh... good! Let me think about where to start."

Xu Heng, "Whatever you want! Say whatever you think of."

Dean Nie, "Ahem! I'm sorry, I'm full of you now."

Xu Heng, "Uh..."

The atmosphere instantly became awkward.

Xu Heng joked, "It's not good for my girlfriend to know."

"Uh...hahaha! Student Xu Heng, stop making trouble!"

The atmosphere eased a little, and Dean Nie was not so nervous.

Dean Nie, "This year's latest official report shows that there are 3 state key laboratories in physics, 6 academy key laboratories, 3 institute-level laboratories, and 8 research centers; there are 2 first-level discipline doctoral training centers, 2 training sites for postgraduates with professional degrees, 2 postdoctoral mobile stations for first-level disciplines..."

"..."

"Integrated configuration of highly flexible, long-life zinc-ion battery, antiferromagnetic metal chromium nitride, black scale, new alloy material, three-dimensional interconnected graphene roll skeleton, etc..."

""Shang Shuwei Kao Lingyao" records that the earth is constantly moving but people don't know it, such as people's observation and thinking in a big boat. In ancient times, people had a simple understanding of the theory of relativity."

"Modern Western Galileo, Newton and others put forward concepts such as inertia and acceleration."

"..."

"Do you think the theory of relativity is far away from us?"

Xu Heng smiled, "If there is no theory of relativity, how do you calibrate a moving clock? How do you tell time and measure distance in daily life? Also, satellite navigation, doesn't it all have the shadow of relativity?"

Dean Nie's eyes lit up, "I didn't expect you to be so good at thinking!"

chat and chat.

Dean Nie suddenly said, "Xu Heng, in your understanding, what is physics?"

Xu Heng waved his hand, "I've never studied such abstruse things! I also ask Dean Nie to enlighten me."

Dean Nie, "From the universe to the sun, to the earth, to human beings, to biological cells, to atoms, to quarks, to..."

"Particle physics..."

"..."

"In fact, there are many kinds of physics, such as physics, astronomy, nuclear science, atmospheric science, oceanography, etc."
