CHAPTER 465: CHAPTER 289: WHO KNOWS HOW THIS THEOREM CAME ABOUT, FEELS LIKE IT’S OUT TO SELL ITSELF_2

"Sure."

"Let’s go."

Everyone nodded, but Bai Bufan was focused, scribbling rapidly on the paper. Hearing the voices, he just slightly raised his left hand and said, "Wait a minute," without looking up.

Then he immediately lowered it and continued pressing on the rough paper, looking increasingly excited.

"No rush, take your time."

Lin Li, seeing this, sat back down, opened his water bottle, and began to drink.

Being in this "Zone" of studying is also a rare occurrence, and sure enough, he was doing math problems.

And at times like these, solving it would greatly benefit Bai Bufan.

Bai Bufan did not disappoint Lin Li. In the next moment, he excitedly stood up, heavily slapped the pen onto the scratch paper, and exclaimed:

"I’ve solved it! Whoa! I’ve solved it!"

"You little devil, what have you solved?"

"The Pythagorean theorem is incorrect!"

"Not bad, pfft—" Lin Li’s thumbs were already up, but the moment he confirmed what he heard, water instantly sprayed out.

Luckily, he was facing Bai Bufan and not the girls.

Bai Bufan’s excitement came to an abrupt halt, wiping the water off his face and looking coldly at Lin Li.

He had been harassed.

But Lin Li was too busy to deal with that now. Pointing at Bai Bufan, he was full of disbelief: "What did you just say? What did you prove is wrong?"

Bai Bufan, who was originally prepared to question Lin Li, heard this and ignored the water on his face. He accepted the tissue handed over by Chen Yu Ying, wiped a couple of times, and excitedly showed his scratch paper to the four present.

He made a solemn declaration—

"The Pythagorean theorem really doesn’t always hold!"

"I know you might not believe it, but listen to me explain!"

"Come, follow my rhythm, let’s use proof by contradiction. First, we assume a²+b²=c² is correct. abc are just algebraic letters that can be arbitrarily set, so for your understanding, we’ll write it as x²+y²=z².

Hey, you smart ones should see it by now."

"See what?"

"Sigh, fools!

Then I’ll have to continue revealing it. Look! On the left, x²+y² is a binary quadratic equation, while on the right, z² is a unary quadratic equation.

Binary quadratic is just unary linear, and unary quadratic linear only costs fifty cents.

This price difference is double, folks, so it’s obviously unequal, which means the assumption doesn’t hold, and the Pythagorean theorem is incorrect!"

Since the entire proof was thought out by himself, Bai Bufan explained very smoothly, in a flowing manner.

Ding Sihan, Chen Yu Ying, Qu Wanqiu: "?"

What fifty cents?

What did I just hear?

Bai Bufan shook his head, realizing his astonishing discovery had indeed completely shocked Lin, Ding, Qu, and Chen. They were staring at the formulas on his scratch paper, speechless.

Understandable.

After all, his discovery was too great.

Lin Li was the first to react. He covered his mouth, his expression somewhat terrified: "Damn, so that’s how it is..."

Ding Sihan, Chen Yu Ying, Qu Wanqiu: "?"

No... You?

Lin Li then sighed and, with even more grief and regret, mumbled:

"Damn, I even recommended the Pythagorean theorem to my friends before, never thought it would collapse like this. Everyone should remember to avoid pitfalls in the future, Old Jian is really harmful, taking any sponsorship deals, teaching any kind of knowledge..."

"Hmm... I think, actually, collapse is normal. When I learned it in middle school, I thought this theorem was not serious, mixing ’legs’ and ’hypotenuse’, seemed popular just by chance," Ding Sihan took a deep breath, nodded, and acknowledged.

Chen Yu Ying and Qu Wanqiu suddenly turned their heads: "??"

No... how come you too?

"Moreover, my research results are not over yet, folks, I’ve just calculated the specific value of π."

"Oh, another expert?"

"Look, π＝兀＝one+son, while Binbin taught us that the sonorous tone has no actual meaning, so π＝one＝1!"

The great mathematician Bai Bufan wouldn’t stop here. He continued to pull out his previous scratch papers, explaining to the others.

"Damn! Bai Bufan, you are indeed a genius!" Lin Li was the perfect foil, harmonizing perfectly with rise and fall in pitch:

"Humans are no longer troubled by memorizing the value of π! The dark clouds over the math building have diminished! Bai Bufan, you’re practically Gauss’s brother, a big ’Gouthus’!"

It seems an all-around development is necessary, those mathematicians of the past, if only they had studied literature well, would have found the value of π earlier.

Ding Sihan also nodded with satisfaction: "A small step for Bai Bufan, a stationary step for humankind."

"Overpraise, overpraise."

The atmosphere in the study room was harmonious, with mutual commercial praise and modesty moments.

Meanwhile, Chen Yu Ying and Qu Wanqiu exchanged glances.

For some reason, it seemed like they were the abnormal ones among everyone there.

Turns out we’re the ones with issues?

In a lack of confidence, let’s take another look.

"Wanqiu, don’t join them, I beg you," pitiful Ying Bao pleaded while holding Qu Wanqiu’s hand.

"Don’t worry, I’m still lagging behind, still a bit too sane," Qu Wanqiu patted Chen Yu Ying’s hand back and nodded regretfully.

"Bufan, are you interested in teaching during winter and summer breaks in the mountain village? I feel you could teach the kids into the jungle."

Lin Li hooked Bai Bufan’s shoulder, treating him like a national treasure—

"Bufan, the country needs teachers like you!"

"Heh—oh—" Bai Bufan still wanted to maintain seriousness, but Lin Li’s two sentences completely broke him, making him burst into laughter.
