Chapter 113: Compared to mathematics, I am truly more skilled at physics

Just as Xu Qingzhou was deep in thought, Xu Zhengyang and the others had already arrived at the classroom.

After Xu Zhengyang's guidance along the way, Kong Xianbo finally recovered some of his former spirit. That's right, we are math majors, why go and compete in physics? Isn't it enough as long as we win in math!

"Old Kong, those few aren't from our class, are they?" Xu Zhengyang pointed at the two unfamiliar boys at the very front.

Kong Xianbo took a glance, shook his head, and said, "These two are here for retakes."

"Retakes..."

Xu Zhengyang shuddered, thinking to himself that he had to do well; he couldn't afford to lose face like that. Moreover, the moment he entered the classroom, he saw a large crowd of people he didn't recognize, and an inexplicable fear rose in his heart.

It was that feeling of going alone into the enemy's base, facing a crowd of strangers wielding knives and guns—it was just too uncomfortable.

Jiao Mingwu sat at the podium, looking at the latest electronic issue of *Mathematical Inventions* sent by Gu Zhizhong. Regarding the application of Euler's formula in wave function representation, he nodded gently, his eyes filled with undisguised admiration.

Jiao Mingwu was in a very good mood and nodded: "Mm, our department has a student who published a paper in *Mathematical Inventions*."

Read! {

"Ah? A junior, publishing an SCI paper in his sophomore year?!" This person exclaimed.

【primes=y(【2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31# Calculate prime gaps gaps=(primes)# Calculate mean and standard deviation】

When constructing the underlying model, in order to better filter prime numbers and find patterns, Xu Qingzhou wrote a Python function.

"Your student?"

After finishing his meal, Xu Qingzhou found an empty classroom. The prime number analysis model constructed so far was only a base model—you could say it was the foundation—and now he needed to add bricks and mortar.

Just two papers? Not a big deal? Xu Zhengyang fell silent. At this moment, he suddenly felt that Old Kong's previous posturing behaviors were quite easy to accept, and he even felt a sense of closeness.

Time passed second by second.

Many journals are printed in advance, so that when readers receive the November issue in October, they don't feel like it's expired.

"I'm fine, but Old Kong and the others have had their Dao hearts collapse."

However, when running it at the supercomputing center, he discovered that when generating all prime numbers less than or equal to 10,000,000—that is, limit=10,000,000—this function would consume a massive amount of memory and computation time.

He was eating at the Third Canteen when Ji Yunshi called to say that the procedures for his second major had been completed. He could just follow Physics Class 1 for his regular classes. As for whether he needed to attend the lectures, that depended on whether Xu Qingzhou had the time.

Xu Qingzhou gently spun the signature pen in his hand, considering how to modify it.

Beside him, Xu Zhengyang and the others also pricked up their ears to listen to the senior and Professor Jiao chatting, lamenting the senior's strong mentality—he was so calm and composed even while retaking a course.

Xu Zhengyang's gaze was incredibly resentful; he gritted his teeth and said, "Old Xu, what the hell is going on here!"

He posted on his social media for the night, put away his phone, and went to eat.

Previously, using his own computer for simulations hadn't resulted in this situation, but using the supercomputer, the problem became quite obvious.

"???"

Xu Qingzhou put down his things and asked worriedly, "Are you all okay?"

!.

"Hmph~ You think others are just like you two tail-enders!"

At 5:30 PM, Xu Qingzhou came out of the server room, lamenting that the supercomputer lived up to its name; its speed was much faster than his computer, and filtering prime pairs was as simple as drinking water.

【# Initialize a boolean array, set all values to true, indicating all numbers could be prime prime=【truefor_inrange(limit+1)】p=2while(p*p# If prime【p】 hasn't been changed, then it is a prime number

Also, the group chat was being bombed with messages.

On this basis, directly using the `primerange` function had the same effect as the previous Python function, but the entire calculation process was simplified a lot.

Damn, this guy is the real king of posturing! Kong Xianbo and Zhai Ziqiang also looked over, wanting to hear what Xu Qingzhou had to say.

"Counting it up, he's still your junior," Jiao Mingwu looked at the person on the left.

Only then did he notice that Gu Zhizhong had sent a message saying the papers were published.

However, while simulating values at the supercomputing center in the afternoon, Xu Qingzhou discovered a small problem.

Being able to skillfully apply wave functions, calculus, and linear algebra meant he was definitely very proficient; this was why he felt at ease letting Xu Qingzhou skip lectures.

Kong Xianbo clutched his chest, feeling like he was having a myocardial infarction. Zhai Ziqiang let out a breath and gave a thumbs up.

Jiao Mingwu swept his gaze around the classroom and smiled: "He didn't come to class today."

if(prime【p】==true): # Update all multiples of p as non-prime】

"It's just two papers, not a big deal. I originally planned to tell you all later." Xu Qingzhou smiled modestly.

Xu Qingzhou was also a bit surprised that two papers were published on the same day.

At 10:30 PM, Xu Qingzhou let out a breath, looked at the screen, and nodded with satisfaction.

For example, the date on *Mathematical Inventions* was November 5, 2014.

That feeling was like having a 1050 graphics card appear inside a top-tier computer.

Stretching, Xu Qingzhou packed his things to return to the dormitory.

Xu Zhengyang was a bit better, but at this moment, he was also staring straight at him.

"I started conceiving these two papers during the summer vacation, and Professor Gu Zhizhong also helped me revise them." Xu Qingzhou explained with a smile.

Xu Qingzhou pushed the door open and entered, only to find the atmosphere in the dormitory very strange. Kong Xianbo sat on his chair with vacant eyes, and Zhai Ziqiang looked at him, wanting to speak but stopping.

"*Mathematical Inventions*? So strong!"

The boy beside him also started laughing, secretly thinking that it seemed normal for him to fail and retake a course.

Of course, although it was the same day, the publication dates listed on the two journals, *Physics Reports* and *Mathematical Inventions*, were different.

To have this level of ability as a freshman—within 10 years, he might have a chance to challenge for the Fields Medal.

"Didn't come?" That boy was stunned for a moment, and after reflecting on it, he asked in surprise: "A big shot who publishes SCI papers can also retake courses?"

Of course, it was mainly Xu Zhengyang's news; Kong Xianbo and Zhai Ziqiang had both fallen into an eerie silence.

The approximate expression of the Prime Number Theorem gives an approximate value for the number of primes $\pi(x)$ less than or equal to a certain number $x$: $【\pi(x)\approx\frac{x}{\lnx}】$. This formula is very accurate when $x$ is large.

"Professor, I see you're in a very good mood today." A senior chatted happily with Jiao Mingwu.

Kong Xianbo secretly let out a breath, clenching his fists, full of drive. Publishing a paper in a top journal as a sophomore—this was the life he should have.

The classroom fell into silence.

Jiao Mingwu glared and said irritably: "Xu Qingzhou, he's a freshman, and he's in this class!"

Professor Gu helped revise it?

Hearing this, Kong Xianbo finally felt a bit better inside. If Professor Gu helped him revise, then... But why didn't Professor Gu sign his name? Not even the name of the corresponding author... Kong Xianbo hadn't asked yet, but Zhai Ziqiang had already discovered the key point: "But Professor Gu teaches math, how did he help you revise a physics paper?"

"Oh, this one, I wrote it myself. Professor Gu only helped me revise the math one, but because the changes weren't big, he said he wouldn't sign his name."

"Actually, I wasn't lying last time; compared to math, I am truly more skilled at physics."
