Chapter 63 Evening Chat

night.

The night sky over Nanjing was tinged with a faint red.

The boys' dormitory at the High School Affiliated to National Taiwan Normal University.

Second floor, room 204.

Half past ten.

The lights are off.

Only the moonlight from outside the window and the faint light from the distant streetlights shone through the window.

The dappled shadows of sycamore leaves are cast on the floor.

Four ninth-grade boys were lying on their respective beds.

After the exam that afternoon.

Everyone is very tired.

The dormitory was very quiet.

All that could be heard was the sound of even, heavy breathing.

And the occasional creaking sound from the metal frame bed when I turn over.

in the dark.

A long sigh came from the lower bunk on the left, near the door.

Her voice was soft and weak, completely lacking the energy she had during the day.

Brothers...

Wang's taciturn voice rang out in the darkness.

My stomach is growling louder than the cicadas outside.

"I feel like I used up three days' worth of food this afternoon. That one question completely drained my brain."

"Even though I ate sweet and sour pork, my stomach still feels empty."

He rolled over and faced the other side.

"Chen Zhuo".

"Could your Inner Mongolian beef jerky... come in handy in an emergency?"

The lower bunk on the right.

Chen Zhuo leaned against the pillow.

His face was not visible in the darkness.

He shifted slightly, and the bed frame made a soft creak.

"On the wooden board at the foot of the bed."

"The kraft paper package is open; feel it yourself."

"Give some to Shi'an and the others as well."

"Oh, my dear brother!"

Wang Huashao suddenly sat up in the darkness.

A rustling sound arose.

He groped his way out of bed and stepped barefoot onto the floor.

He walked to the foot of Chen Zhuo's bed and touched the brown paper package.

"Shi'an, Kai-ge, and He Gui."

Wang spoke little and lowered his voice.

"Want some? I'll give each of you one."

"Give me one."

Miao Shi'an sighed from the lower bunk opposite him.

"I wasted six sheets of paper this afternoon on scrap paper, all of them useless energy conversion equations."

"In the end, I crossed them all out with a pen."

"My wrist is still cramping, so I'm chewing on something hard to exercise my jaw muscles."

"I want one too."

He Gui, who was in the corner, said something quietly.

Wang, a man of few words, distributed beef jerky in the dark.

In the dormitory.

Immediately, the sound of down-to-earth, crunchy chewing filled the air.

That kind of hard, dried beef is very difficult to chew; you have to use your molars to tear it apart.

The lower right bunk by the window.

Zhou Kai was lying in bed.

He was also holding a piece of beef jerky in his hand.

He took a bite.

The salty and savory flavor of the dried meat spread throughout my mouth.

Zhou Kai chewed on the dried meat.

I rolled over, lay flat on my back, and stared at the dark ceiling.

His tone carried an extremely frankness, a thirst for knowledge about physics itself, and even a touch of self-deprecation.

"Chen Zhuo".

Zhou Kai's voice was gentle, slowly spreading through the night.

"I almost racked my brains when I was working on that problem this afternoon."

"When I was halfway through the derivation, I actually realized that applying Ohm's law to a rotating motor was not right."

He paused for a moment, then chewed a piece of tendon forcefully.

"But I just don't know how to write the equation for the conservation of energy."

"I always feel that I can't write anything that's not taught in books."

"How did you manage to turn that corner?"

"How dare you isolate Joule heating to counteract the back electromotive force?"

Miao Shi'an, who was standing next to him, also stopped chewing.

He smiled and echoed the sentiment.

"yes."

"I'm stuck here too. I feel like something's missing, like a puzzle piece is missing."

Chen Zhuo leaned against the headboard.

He was holding a half-eaten beef jerky in his hand.

The moonlight from outside the window shone on the edge of his bed.

He didn't go on to explain any profound principles of electromagnetism.

They didn't lecture like a teacher would.

"Actually, when I was doing this problem, I didn't think that deeply about it."

Chen Zhuo took a bite of the beef jerky.

"I just suddenly remembered that my childhood friend used to play with Audi Double Diamond four-wheel drive cars."

As soon as those words were spoken...

The chewing sounds in the dormitory suddenly stopped for a moment.

Chen Zhuo continued speaking.

His voice carried a lighthearted quality unique to boys, reminiscing about childhood toys.

"You've all definitely played it."

"Those four-wheel drive vehicles, equipped with Nanfu batteries, can run very fast when placed on the ground."

"But what if it hits a corner or gets stuck somewhere and can't move?"

"If the wheel can't turn, the motor will be stuck inside, struggling to keep up."

Chen Zhuo stared at the ceiling.

"At this point, you pick it up and touch the motor."

"It will be very hot to the touch."

"You can even smell a burnt plastic odor."

In the darkness, several boys listened quietly.

"The electricity wasn't converted into power; it was all turned into heat."

Chen Zhuo's voice was very steady.

"So I think that when a motor is stuck, it becomes a pure resistor, and all of its energy is used to generate heat."

"But when it starts spinning, the amount of heat generated must be less than the energy used for spinning."

"Following this line of thought."

"The formula for the conservation of energy naturally follows."

In the dormitory.

There was a two-second silence.

The only sound was the rustling of the sycamore leaves in the breeze outside the window.

then.

A burst of frustrated yet joyful whispers erupted.

"Oh my god!"

Wang Huashao slapped his thigh hard, making a crisp sound.

"Audi Double Diamond! Dragon Head and Phoenix Tail!"

"A few years ago, when I was modifying the motor of a four-wheel drive car, I wrapped copper wire around it myself and burned my hands several times!"

"When that motor jams, it's so hot you could fry an egg in it!"

"How could I not have connected this to the test paper this afternoon!"

Wang, who rarely spoke, rolled over in bed.

His tone was full of regret for missing out on a hundred million.

"What a huge loss! An absolute huge loss!"

Zhou Kai is in bed.

He couldn't help but laugh out loud.

It was a sense of relief after truly understanding, and a complete comprehension of Professor Wang's initial show of force.

"I'm impressed."

Zhou Kai smiled and shook his head.

"Professor Wang will talk about the real world this afternoon."

"So this is where they were waiting for us."

"Physics is life. We've really gone crazy from doing those ideal model problems. We've even forgotten about things like four-wheel drive cars burning out their motors."

He returned to the corner.

He added quietly.

"that..

"I used to play with a four-wheel drive car that I made myself. To make it run faster, I added two batteries."

"Later, the car got stuck under the bed, and the motor started emitting a plume of smoke... It even burned a hole in the bed."

He Gui had barely finished speaking.

The four boys in the dormitory couldn't help but burst into laughter in the darkness.

The academic pressure of the daytime was gone.

They've shed their airs of being number one or number two in the province.

In this somewhat dull dormitory room 204.

Several fifteen- or sixteen-year-old boys were chewing on hard Pimon beef jerky.

The shared childhood memory of four-wheel drive cars burning out motors created an extremely strong resonance.
