39: Chapter 39 The Shining Goal 39: Chapter 39 The Shining Goal Qiao Yu didn’t care what the teachers were thinking.

His keen anticipation for Little Alibaba’s math competition had even faded.

Yes, at this time, Qiao Yu had focused most of his thoughts on Number Theory, especially Prime Numbers and large Prime Numbers.

Qiao Yu had his own understanding of Mathematics.

He always believed that Mathematics, simply put, is a discipline that studies patterns.

Whether it’s the distribution of Prime Numbers, divisibility, or congruence relations, in simple terms, they’re all patterns.

He believed that if he could find those potential, undiscovered patterns, he could master a method for quickly factoring large Prime Numbers and even ultra-large Prime Numbers.

As long as he mastered this method, the wealth of the entire world would bow to him.

It’s no exaggeration to say, he’d make a fortune just by collecting protection fees.

Yes, Qiao Yu had it all figured out.

If he could truly solve this mystery, he would then establish a company dedicated to providing password security services to major companies and institutions in need.

If he really succeeded, perhaps those richest people now affectionately called Daddy would have the urge to call him Daddy Qiao.

Qiao Yu wasn’t interested in becoming a daddy, but he was really interested in money, which made his interest in Mathematics unprecedentedly intense, especially his interest in numbers.

Yes, not just Prime Numbers, but numbers, or more accurately, integers.

Because Qiao Yu believed that to fully understand Prime Numbers, it was impossible to bypass the relationship between Prime Numbers and other integers.

For example, the book mentioned the quadratic reciprocity law, a basic tool in classic Number Theory.

Although it mainly describes the quadratic residue relationship of two odd Prime Numbers, to Qiao Yu, it must also directly involve the relationship between Prime Numbers and other integers.

If Lan Jie knew Qiao Yu’s current mental journey, he would probably be very pleased.

Under his guidance, Qiao Yu developed a strong, even passionate interest in Number Theory, which was what Lan Jie most wanted to see.

Considering the talent Qiao Yu showed, it was really a pity not to study Number Theory.

Of course, there would surely be some surprise, because the content on Algebra and Number Theory was actually a bit too advanced for someone of Qiao Yu’s age.

But no matter what, with the drive to become the richest, Qiao Yu’s feelings for Number Theory, previously deemed too profound and intimidating, vanished, and his confidence quickly inflated to infinity.

If the good guy were to ask Qiao Yu his thoughts on Mathematics now, the answer would probably be love.

…

“Qiao Yu, why have you seemed drained these past two days?” As they were having breakfast, Xia Keke stared at Qiao Yu and asked.

“Have you ever seen the moon at 3 a.m.?” Qiao Yu casually replied, receiving a roll of eyes in return.

“Not sleeping at midnight, what are you doing?”

“Of course, studying, studying makes me happy!”

“Studying in the middle of the night?

What are you studying?”

“Mathematics!

You’re still young, you don’t understand how truly joyful learning real Mathematics can be.”

Qiao Yu said this very seriously, and Xia Keke, who thought she knew Qiao Yu well, could tell he was genuinely invested.

Curiously, she asked, “What is real Mathematics?”

Hearing this question, Qiao Yu quickly finished his last bite of food and became spirited: “For instance, you know Prime Numbers, right?”

Xia Keke rolled her eyes again: “Obviously, I’m in the Rocket Class, we learned about Prime and Composite Numbers in first grade.”

“Then do you know why there are infinitely many Prime Numbers?” Qiao Yu nonchalantly pursued.

Xia Keke furrowed her brows and pondered for a moment before shaking her head and saying, “I remember the textbook just says there are infinite Prime Numbers, isn’t that a theorem?”

Qiao Yu, full of enthusiasm, said: “No, no, no, in Mathematics, theorems are only theorems once proven.

Actually, it’s quite simple to prove.

First, assume there are finitely many Prime Numbers, from P1 to Pn, and then construct a new number N, which equals the product of all Prime Numbers plus 1.

Because we previously assumed there were finitely many Prime Numbers, N divided by any Prime Number Pi would have a remainder of 1.

This means that the new number N cannot be divided by any Prime Number.

So, N is either a new Prime Number or has a Prime factor different from all others, which proves there are infinitely many Prime Numbers.

This is real Mathematics.”

Xia Keke smirked, though her grades were indeed good, her Mathematics could only be described as generally excellent, she found it hard to GET to the excitement that thrilled Qiao Yu, and she quickly changed the topic: “By the way, how did your test go yesterday?

They said the last question in Physics was quite difficult.”

“Yesterday’s Physics test had a hard question?

Aren’t you guys the Rocket Class?” Still in a state of excitement, Qiao Yu casually scoffed.

“The last circuit problem wasn’t hard?

Many people got it wrong!” Xia Keke emphasized angrily.

“Circuit?

Oh, was that the one about comparing which method is more energy efficient, forgetting to record the proposal?

It only involved two laws, Joule’s Law and Ohm’s Law, and it’s called difficult?

It just needs a slight transformation.

So the final answer must be the second method, connecting the heating wire in series at point B.

The newly obtained resistance value should be approximately 18.33 ohms.”

Qiao Yu said confidently, given it was just yesterday’s test content, it would be hard to forget.

“I got it right too, but many people got it wrong!” Xia Keke emphasized once more.

“Oh, you’re awesome!” Qiao Yu insincerely praised her, but couldn’t resist adding: “But those who find such a problem difficult, barely managing to be in Class One, right?

Why does the Rocket Class sound like it doesn’t live up to its name?”

It wasn’t a lack of emotional intelligence, but since Xia Keke had been his little tagalong for many years, he couldn’t help but tease her a bit.

Most importantly, now he didn’t need to pretend anymore, he could lay it all out, the things learned in middle school were indeed quite simple.

“If it’s so simple can you get a perfect score?” Xia Keke asked.

“Sure, no problem with Math, Physics, and Chemistry, the other subjects, teachers would dock points, as it’s just a mock exam, they fear I’ll get arrogant.

But if this is the level of your Rocket Class, stomping on you shouldn’t be an issue.” Qiao Yu said honestly.

Xia Keke sneered: “Heh…”

She believed Qiao Yu’s words in her heart and was quite happy, but seeing Qiao Yu’s full-of-confidence look, she couldn’t help but want to take him down a peg.

Obviously, her attitude had no impact on Qiao Yu.

“Many times it’s just so helpless, some people never realize how weak they originally were until they try harder.

For example, those classmates of yours who found this Physics test difficult, I suggest they should accept their mediocrity sooner, be kinder to themselves, don’t push themselves so hard, life isn’t worth it.”

From these words, one can tell that Qiao Yu is an earnest person.
