Killing People and Destroying Hearts (Seeking Follow-up!!!)

A few seconds after Little Ox knocked on the door, a male voice came from inside. The owner of the voice was Hooke:

"Come in."

Seeing this, Little Ox took a deep breath and pushed the door open with Xu Yun.

Hooke's guest room was a one-bedroom, one-living room layout. This type of suite, which would be marked as a suite and be extremely expensive in most hotels in later generations, was standard in the 17th century.

At this moment, the bedroom door was already closed. Hooke was sitting at the desk in the living room facing the door, smoking his pipe in one hand and seemingly flipping through a book in the other.

Seeing Little Ox and the other appear, he didn't get up to greet them. Instead, he leaned back comfortably in his chair:

"Student Newton, it's only been... oh, four days, right? Why are you here so soon?

Could it be that you couldn't contact Barrow? Or have you solved that problem?"

Hooke's last sentence carried a distinct tone of sarcasm, looking down from above with a deep gaze.

In his opinion, the purpose of Little Ox's visit must be to inform him that he couldn't contact Barrow.

Four days was clearly not enough time for a round trip by mail, and if Barrow was in Lincolnshire, he would definitely have come with Little Ox to find him today.

He knew Barrow fairly well; he had a tiny bit of responsibility, and even if he couldn't solve the problem, he wouldn't send his student to take the fall.

Therefore, it was obvious that there was only one possibility:

Little Ox had searched at home and found that he had lost his teacher's contact address, or was told that mail delivery was temporarily suspended due to the epidemic, and could only come to inform him of the matter.

At the same time, this action also indicated another point:

He had attempted to calculate this problem but was unable to.

As for the possibility of Little Ox solving this problem...

He was more willing to believe that someone had deduced the specific formula for Universal Gravitation during his lifetime than to believe that a young man could solve his problem.

Even if he was Trinity College's first fee-waiver student in fifteen years, it was impossible!

And just as Hooke was contemplating how to mock Little Ox, he heard Little Ox's voice, tinged with a strange meaning:

"That's right, Mr. Hooke, I solved this problem."

"I know, it's indeed difficult for you. Wait?!"

Hooke, who was about to continue his mockery, suddenly realized something was amiss as he spoke. His smile froze on his face, and he stood there dumbfounded.

He stared blankly for more than ten seconds before suddenly sitting up straight in his chair, staring intently at Little Ox:

"What did you just say?"

Little Ox shrugged, took out a prepared manuscript from his person, and handed it to him:

"The solution is here, provided you can understand it, Mr. Hooke."

"Nonsense, that's impossible!"

Hooke cursed rudely and snatched the manuscript from Little Ox without any grace. He spread it out directly on the table and began to read:

"Specific vibration frequencies correspond to specific curves derived from coordinates."

"The formula for linear strain within a unit body, Σa=(Σx+Σy)+(Σx-Σy)cos2α+yxcos2α. Brilliant, brilliant."

"d(△l)=εxdxcosα+εydysinα-γxydxsinα

εα=d(△l)/ds

=(εx+εy)/2+{(εx-εy)/2}cos2α-{(γxy)/2}sin2α" (Someone asked me what the equation was, I've written it out this time)

"Horizontal displacement S=ε1, then... hmm?"

As he was calculating, Hooke's pen suddenly stopped at a certain point.

He drew a line under "→0" and asked Little Ox:

"What does this mean?"

Seeing that it involved the core of his current research, Little Ox naturally wouldn't reveal it casually—although this man was petty and easily angered, he was actually very cunning. Hooke had been tricked when deriving Universal Gravitation.

So Little Ox hummed casually:

"It's just an abbreviation for approaching; you can consider it a decrease trend of the -1 power order.

Mr. Hooke, you can draw a stress distribution curve on the line of central height. As the displacement approaches the load-bearing edge, you will find that the three stress fields tend to be consistent at a distance twice the distance from the load boundary."

Little Ox's tone seemed relaxed, with a hint of "those who know, know."

But in reality, this statement contained a lot of crucial information—especially the latter half.

This sentence actually involved Saint-Venant's principle, a fundamental theorem proposed by the Gaulish scientist Saint-Venant in 1855, which was still nearly 200 years away.

But after Xu Yun processed it, it became the work of the all-around genius Han Li.

Saint-Venant applied many concepts of infinitesimals in deriving the problem of zero force systems and strain energy density. Therefore, there was a very subtle equivalent recursion between the two, which could be used to explain the concept of infinitesimals.

After all, at this time, before the generalized Hooke's Law was proposed, no one knew what an equivalent force system was.

At worst, the tendency of the stress field could be attributed to a positional phenomenon—Little Ox saying he had created a new mathematical tool might attract some hatred, but saying he observed a phenomenon in experiments that followed a certain pattern, even Hooke wouldn't say anything about such an explanation.

Of course...

This is also related to Hooke's problem, which only involves the second-order Taylor expansion.

The entire process, apart from some calculations, does not require the mathematical tool of Calculus in most cases. Only the conceptual interpretation is needed.

Therefore, after Little Ox exploited a bug 200 years ago to conceal the true meaning of infinitesimals, Hooke quickly deduced a brand new result:

"With ρx and ρy unchanged, this is an elastic force within a logical framework? Wait, no!"

As he was calculating, Hooke suddenly looked up:

"What about the stress-strain relationship? How do we derive the linear strain occupied by the medium?"

Seeing Hooke's exasperated expression, as if he had encountered the author's cliffhanger, Little Ox shrugged at him innocently and said:

"I'm sorry, Mr. Hooke, Professor Barrow only taught me this knowledge.

If you want to understand the subsequent content, you can wait until the epidemic is over and personally visit Trinity College to ask for guidance.

Given his personality, I'm sure my teacher will patiently answer you."

"You're dreaming!"

As soon as Little Ox finished speaking, Hooke abruptly stood up, his face looking extremely terrifying in the dim light:

"You want me to ask him questions? I'd rather wait for the end of the world!

You little brat, I'm telling you, don't think you're so great just because you solved this little problem. You'll regret it one day!

Regret becoming Barrow's student! Regret saying these words today!"

Xu Yun, watching the impotent rage of Hooke, shook his head slightly in his heart:

Thank goodness this is reality. If this were in a game, and I sent a question mark right now, Hooke would probably smash his computer in frustration.

Beside Xu Yun, Little Ox, uncharacteristically, wasn't angry. Instead, he pouted provocatively:

"Mr. Hooke, whatever you think is fine. I won't disturb you any longer. Please, make yourself at home."

With that, he pulled Xu Yun and left the room.

As they reached the doorway, Little Ox 'suddenly' seemed to remember something. He let out an exaggerated "Oh" and said to Xu Yun:

"Fat Fish, do you know where Teacher Barrow is right now?"

After a few days of getting along, Xu Yun had gotten to know this ancestor somewhat. So, despite not understanding why he brought this up, he cooperated and replied:

"I don't know."

"Ah, that's just how Teacher is. He likes to wander around. But with Teacher's wife accompanying him, I'm sure he's living very happily."

"Teacher's wife?"

"Yes, you don't know? Teacher's wife is named Eloise Bryce. She's a great beauty. She was also a renowned scholar at Oxford University. But one year, during an exchange competition between Oxford and Cambridge, she faced off against Teacher, and Teacher reversed the score with a 3-0 sweep. Ever since then, she's been pursuing Teacher."

Little Ox hadn't even finished speaking when a sound of a heavy object falling came from the room behind them, along with a roar tinged with a hint of crying.

"Get lost!!!!!"
