96 precise world

The campus of Normal University cannot be said to be very luxurious, but as a university, it still takes a long time to walk, so it is extremely important to have a car. 【】

Xu Zihao's high-end convertible car has not been used since he entered the school, because no one else in the dormitory has had time to buy a car, and everyone is in a group activity, so he has always accompanied them to go, this is now alone Ride your bike and go straight to the library.

There are few people on weekends, and it is so early, the campus looks very empty.That is to say, this group of "troops" that have just disappeared will naturally wake up at this point. Of course, they will also integrate into the rhythm of the entire university in a short time.

He had just taken Zizi car out of the shed, wiped off the dust on the seat cushion and faucet, and when he looked up, he saw a girl in front of him waving to him.

Yu Yuan also stopped suddenly after seeing Xu Zihao. The two of them seemed to be wondering why the other got up so early.

After asking Xu Zihao's destination without asking for permission, Yu Yuan unceremoniously sat in his back seat, this action seemed to be a habit.It was hard for Xu Zihao to refuse, and Yu Yuan had hitched a ride with him countless times when he was in high school, but so far, Yu Yuan seemed to be the only one who had sat in his back seat.

At the beginning, the two were still discussing what kind of university they would be admitted to in the future, and where they would go to study, but they didn't expect that they could become classmates now, and the dormitories lived so close together.

Four years is enough time for many things to happen.A voice in Yu Yuan's heart told her that at least now she could see him often, and even go to school and eat together.

Today, however, she was going to the association for an interview, and she happened to be on the way.

There are generally no classes on weekends, but for busy people, it is almost always filled with various activities.Associations, clubs, and student unions, either choose to hold meetings at this time, or just hold meetings, and groups such as art troupes, dance associations, and martial arts associations will have at least one group rehearsal on weekends, and they will have at least one group rehearsal on weekdays. Take a time to come out, after school in the evening or afternoon.

Xu Zihao pedaled the bicycle, and felt a signal coming from his feet, not very strong, but a faint signal. At that time, he said with a smirk: "Yu Yuan, compared with when you were tall, you must have gained weight. Let me tell you, if you eat so much during military training, you must gain weight."

Yu Yuan frowned, pinched his waist from behind, and said angrily: "It's not that obvious, I can't tell it by comparing photos. Don't talk nonsense, the food that you ate too much during the military training was digested by the military training." , did not gain weight, no!"

"I didn't say the fat is on the face, it must be fat anyway, I'm sure."

Yu Yuan was really unhappy, and patted him: "Hey, do you know how to chat? You also said. Yes, yes, it's fat, a little bit, it's all your fault, you didn't stop me at the beginning, that's why you got fat , you are responsible."

"What's the responsibility of being fat? I just said that you are fat, but I didn't say that being fat is bad. Even if I meant to laugh at you, it's just an idea. It hasn't become a reality yet, and you have no evidence. Why? Let me be responsible. Everyone speak up and be reasonable.”

"If you don't tell me, it's your fault."

Xu Zihao's words felt wrong as soon as he uttered them, but he didn't expect that the more wrong and outrageous he got, the result was Qing's fist on the back.

Fighting, Yu Yuan has already arrived at the station.In a teaching building next to the library, the classrooms are available for students to apply for holding some conference activities when there are no classes.

"After my interview, you come to pick me up, and we will have dinner together." Yu Yuan ordered.

"Will you please?" Xu Zihao said cheekily.

"I'll treat you to the cafeteria." Yu Yuan also replied directly.

"Forget it, let me invite you to go out to eat a cheat sheet. I found a restaurant that is economical and affordable yesterday. How long will you be interviewing?" Xu Zihao cried, instinctively resisting the food in the cafeteria.

"I don't know, it should be over before 11 o'clock."

"Call me when the time comes. Well, little fat girl." Anyway, she has already been pinched, and it still feels unfair not to despise her.

By the time Yu Yuan reacted, Xu Zihao had already stepped on his bicycle and disappeared in a flash.

Every floor of the library is stocked with various books by category. Most people will check the types and quantities of books they need, their collection locations on the computer on the first floor, and go straight there.

In Xu Zihao's mind, he already knew about it, but what he didn't know was what kind of book to read.

Maybe the feeling will tell itself.

Xu Zihao took out a coin and tossed it upwards, deciding that if it was the national emblem, it would go up, and if it was a word, it would be this floor.

As a result, he threw the national emblem 8 times in a row, and the height of each throw was the same as the height of his hand. Only then did he confirm that he could now precisely control his force, and he had reached such a fine level. Degree.Even sometimes you don't have to try too hard, it's just a feeling.

This is already the top floor of the library, and he wanted to use coins to judge whether he was going left or right, but he thought about putting the coins away again.Because of this kind of result that can be controlled, why bother to lie to yourself to do it one more time.

He turned to the left, and the books here were related to his major, they were all engineering books.

After walking two steps, there was a class of textbooks on the bookshelf. The cover made him feel very familiar. This book was called "Engineering Drawing", and their class this semester had this class, but in the version, this book Books are older.

Xu Zihao suddenly thought of something, took out the book and flipped through it.But after a few minutes, the world as far as his eyes could see was full of numbers.

This kind of thing happened a long time ago. At that time, Xu Zihao could quickly feel his length, width and height when he was fighting. What kind of distance to keep with people, and what kind of moves to capture people.Therefore, when facing the 1.9-meter-high fire, he still faced it calmly and easily jumped onto the beam.

To be honest, that kind of judgment is of great benefit for him to use throwing knives and even play parkour, and he can be sure of almost everything.And now, these numbers have a new concept.

It turned out that what he was only in contact with was the long, wide and high curtain, but now the engineering drawing adds the concept of radian.It used to be that a circle was described by its diameter and radius, but now that this thing was introduced, Xu Zihao suddenly realized the description of a curved surface, because these things can also be described by radius and angle.

As a result, the world in Xu Zihao's eyes has become wider, and many things have been defined, so that in the entire three-dimensional world, nothing can be described and accurately expressed.

It seems interesting.Xu Zihao thought about it, and he knew what the next book he wanted was.

He came to another floor of the library, where most of the books on physics were piled up.Soon, he found this book on mechanics.This book is separated separately for mechanics, and it is different from his "University Physics" textbook.But this book is obviously more difficult, because there are many applications of calculus formulas on it.

He managed to finish the book, and found that apart from some newly introduced things, there was not much difference between him and Gao. The biggest difference was the use of new concepts to describe and calculate forces.However, the result obtained by this calculation was originally impossible to calculate.

Now that it's all in his head, it doesn't matter if he can't understand it for the time being, because Xu Zihao knows where the key to solving this problem is, "High Numbers", the tree that is said to have many people hanging on it.

There are many versions of the tutorial materials of "Advanced Mathematics", and there are also a lot of them, but there are not many left on the bookshelf.Many people have already taken the lead, and the content of this course is really in demand.But Xu Zihao believes that it is not because everyone is so interested in this course, but because of the fear and awe of the difficulty of this course and the terrible failure rate.

After learning the detailed explanations in the tutorial materials, Xu Zihao also gradually realized the difficulty.It is said that the derivative is turned over to be calculus, but one sentence conceals all the hidden difficulties. When fixed and unfixed things are put together, the fixed one is obviously much simpler.Difficulty tends to increase with uncertainty.

Xu Zihao was very careful, and savored his concept guide carefully, and finally formed various dimensional space graphics in his mind, and finally felt a sense of enlightenment.I feel that the things described in this whole book are extremely incisive, but they are all summed up by mathematicians in the 18th century, and I also admire them.Of course, Xu Zihao used empathy to think about it. These things seemed to be of little use to Xiaozhi and the others, and they were useless in life.

As for Xu Zihao, he doesn't think so, at least, according to Sankai's local gravity, ground friction, lever effect caused by the distance of the axle, etc., after quick calculations in his head, he came to the conclusion that , Yu Yuan was 6 to 7 catties heavier than before the end of the college entrance examination.There is still a big error in this data. If Xu Zihao made a dramatic estimate based on his current ability, it would be about 63 catties.Perhaps after accumulating more actual situations and analysis results, this data can be closer to the real value, and can be accurate to more digits after the decimal point.

As for whether this result was useful to him, Xu Zihao didn't care that much.It will always be useful, at least when you meet someone in the future, instead of saying "he hit me hard; he hit me hard..." you can say "he hit me with 35n force, I touched an area of ​​23 square centimeters, the force time was 045s, and my pain level... ".

For the first time, Xu Zihao felt that the phrase "If someone offends me, I will pay you back twice" is really achievable, and it can indeed be accurate to "double."
