Into Unscientific

  Chapter 38 Killing and punishing the heart (please read more!!)

   A few seconds after Maverick knocked on the door, a male voice came from the room, and the owner of the voice was Hook:

"come in."

   Seeing this, Maverick took a deep breath, and led Xu Yun to push open the door.

  Hooker's guest room has a one-bedroom-one-living room layout, which was marked as a suite by most hotels in later generations and was extremely expensive, but it was a standard configuration in the seventeenth century.

  At this time, the door of the bedroom had already been closed, and Hook was sitting on the desk in the living room opposite the door, smoking a pipe in one hand, and seemed to be flipping through a book with the other.

   Seeing the two Mavericks appear, he did not stand up to greet him, but leaned back on the chair comfortably:

   "Student Newton, it's just passed. Oh, four days, four days, right? Why did you come here?"

   Could it be that you can't get in touch with Barrow? Or did you solve that problem? "

  Hooker's last sentence carried obvious sarcasm, condescending and deep-eyed.

  In his view, the purpose of the Mavericks' visit this time must be to prepare to inform him that he cannot contact Barrow:

  Four days are obviously not enough time to spend a letter in different places, and if Barrow is in the Lincolnshire area, then he will definitely come to find himself with the Mavericks today.

  Baro is a person he knows quite well, and he has a slight sense of responsibility. Even if there is no problem, he will not let his students come to pick up the bag.

   So it is clear that there is only one possibility at the moment:

  After searching at home, Xiao Niu found that he had lost his teacher’s contact address, or was told that the mail of the letter was temporarily suspended due to the epidemic, so he had no choice but to come to tell him about it.

   At the same time, this move also indicates another point:

  He tried to calculate the problem, but couldn't do anything.

   As for the possibility of Mavericks unraveling this.

  He would rather believe that someone deduced the specific formula of gravity while he was alive than believe that such a young man can solve his own problems.

  Even if he is the first fee-reduction student of Trinity College in fifteen years, it is absolutely impossible!

   While Hook was thinking about how to mock the Maverick, Maverick's voice with some inexplicable meaning came from his ear:

   "Yes, Mr. Hooker, I solved this problem."

   "I know, it's really difficult with your ability. Wait?!"

  Hook was going to continue to ridicule, but suddenly found something wrong while talking, the smile froze on his face, and he stood there in a daze.

   He was in a daze for more than ten seconds before he sat up straight from the chair and stared at the calf:

"what did you just say?"

   Maverick shrugged, took out a written manuscript from his body, and handed it to him:

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

   "Nonsense, it's impossible!"

  Hook cursed a curse word, grabbed Mavericks’ manuscript without grace, spread it out on the table, and read it like this:

   "A specific vibration frequency corresponds to a specific curve to derive coordinates."

   "The linear strain formula Σa=(Σx+Σy)+(Σx-Σy)cos2α+yxcos2α in the unit body is wonderful, wonderful."

  "d(△l)=εxdxcosα+εydysinα-γxydxsinα

  εα=d(△l)/ds

  =(εx+εy)/2+{(εx-εy)/2}cos2α-{(γxy)/2}sin2α" (Someone asked me what the content of the equation is, so I wrote it out this time)

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

   Counting and counting, Hook's pen suddenly stopped at one of the positions.

  I saw him draw a horizontal line under "→0" and asked Maverick:

"What does it mean?"

  Seeing that it involves the core issues of his current research, Mavericks will naturally not disclose it casually—don’t look at this petty and irritable person, but in fact he is a very thief, and Hook was tricked when he deduced universal gravitation.

  So the Maverick hummed casually:

  "It's just an abbreviation for approaching, which can be seen as a decreasing trend of the -1 power level.

  Mr. Hooker, you can draw a stress distribution curve on the central height line, and the displacement is close to the side where the load acts, and you will find that the position where the three stress fields tend to be consistent is twice the distance to the load boundary. "

   Mavericks' tone looked very relaxed, with a taste of "knowing everything".

   But in fact, this passage contains a lot of key information—especially the second half of the sentence.

  This sentence actually involves the content of Saint-Venant's theorem, which is a basic theorem proposed by the Gaul scientist Saint-Venant in 1855, and it is still 200 years away from now.

  But after being processed by Xu Yun, it became the handwriting of the all-round genius Han Li.

  Saint-Venant applied a lot of basic concepts of infinitesimals to the problem of deriving the zero-force system and strain energy density, so there is a very subtle equivalent recursion between the two parties, which can be used to explain the concept of infinitesimals in scale.

  Anyway, before the generalized Hooke's law was proposed these days, no one knew what the equivalent force system was.

It’s a big deal to attribute the tendency of the stress field to a positional phenomenon—Xiao Niu said that he created a new mathematical tool, which may attract hatred, but he said that he observed a certain phenomenon in the experiment, even if this explanation is nonsense. K wouldn't say anything.

Of course.

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

   Except for some calculations in the whole process, in most cases, the mathematical tool of calculus is not needed, as long as the interpretation of the concept is used.

  So after Mavericks developed a bug 200 years in advance to cover up the true meaning of infinitesimal quantities, Hook quickly calculated a brand new result:

   "When ρx and ρy remain unchanged, this is an elastic force within a logical framework? Wait, that's wrong!"

   Counting and counting, Hook suddenly raised his head:

   "What about the stress-strain relationship? How to derive the linear strain of the space occupied by the medium?"

  Looking at Hook with a crazy face as if he saw the author's broken chapter, Mavericks spread his hands towards him, and said innocently:

   "Sorry, Mr. Hook, Professor Barrow only taught me this knowledge.

   If you want to know the follow-up content, you can come to Trinity College for advice after the epidemic is over.

  With the character of the teacher, I am sure he will answer you patiently. "

   "You're daydreaming!"

   As soon as Maverick finished speaking, Hook stood up suddenly, his face looked extremely scary in the shady environment:

   "Wants me to ask him questions, wait for the end of the world!

  Little zei, let me tell you, don’t think it’s a big deal if you solve this problem, you will regret it one day!

   Regret being Barrow's student! I regret what I said today! "

   Xu Yun on the side looked at the impotent and furious Hu Ke, and shook his head slightly in his heart:

   Fortunately, this is in reality. If there is a question mark in the game at this time, Hook will probably break the defense and smash the computer.

  Beside Xu Yun, Maverick was rarely angry at this time, but curled his lips in embarrassment:

   "Mr. Hook, do whatever you think, I won't bother you, please do what you want."

  After speaking, he pulled Xu Yun and left the house.

  When he walked to the door, Xiao Niu suddenly thought of something, exaggeratedly said, and said to Xu Yun:

   "Fat fish, do you know where Mr. Barrow is now?"

   After getting along with each other for a few days, Xu Yun had a little understanding of this patriarch, so although he was puzzled why he started talking like this, he still cooperated and said:

   "I don't know."

   "Hey, the teacher is like this, he likes to run around, but with his wife by his side, he must be very happy."

   "Teacher's wife?"

"Yeah, don't you know? The teacher's wife is called Ilo Bryce, she is a beautiful woman. She is also a well-known student at Oxford University, but one year she met her teacher in the exchange competition between Cambridge and Oxford. , the score was reversed by the teacher in a series of three, and since then I have been chasing the teacher backwards."

   Before Maverick finished speaking, there was a sound of heavy objects falling from the room behind him, as well as the sound of a broken defense with a little crying.

   "Get out!!!"

Note:

  The derivation here is actually the generalized Hooke's law. The generalized Hooke's law in the three-dimensional case is three equations, and f=k·x cannot be directly derived.

  Baro in history did not solve this problem, and was forced to be miserable.

  From today to Tuesday is three days of life and death, begging for further reading! !

  The last book was updated with 25,000 words within 35 hours, and it will be updated after it is put on the shelves. Be sure to follow up, everyone! !

   I really should have listened to the comments, and shouldn’t have watched Knife in the Snow, what’s the slow motion here.
