Looking at the math problems he had done, Zhang Yang put the piece of paper in the book with a proud expression. He felt a great sense of accomplishment. He estimated that this problem was placed in it because a classmate couldn't solve it.
Zhang Yang didn't know that while he was concentrating on doing the questions, the old man he met during the day was looking at him not far away, seemingly thoughtful.
…
That night, Zhang Yang slept well. He had money and slept soundly. But when he was lying on the bed, the old man was sitting on the desk. There was the "Principles of Computational Fluid Dynamics" on the desk.
The paper was held in the old man's hand.
This is a three-dimensional geometry that only Harvard Polytechnic students can understand. As a rubbish school where few people even learn plane geometry well, such a person appears, which shocks the old professor.
Although the old man lives in the College of Arts and Sciences in City C, he is actually a professor at Harvard Polytechnic Institute. After retirement, he returned to his hometown to take care of his old age. He only occasionally gave guest lectures in the school.
Of course, what shocked the old man was not that Zhang Yang solved this problem, but Zhang Yang's method of solving the problem. This problem was solved not only with the knowledge of solid geometry, but also with plane geometry. This way of solving the problem allowed the old man to solve it.
All were full of excitement.
Because the method of solving the problem was too simple, it was so simple that he could not believe it. Zhang Yang first used plane geometry to deduce several formulas of solid geometry, and then used the formulas he deduced to solve the problem.
The old man didn't know that Zhang Yang had good intentions. He was afraid that the classmate who left the note wouldn't understand, so he used the simplest method. He had no idea that his good intentions would make an old man so shocked.
The old man sighed and gently put down the paper in his hand. He felt a little excited. This feeling had not appeared for a long time. I remember that this feeling occurred many years ago. The old man couldn't help but feel in his eyes.
A flash of sadness...
…
There was a professional class this morning, and Zhang Yang got up early. Whether he was a junior or a senior, Zhang Yang usually took professional classes. He had his own set of standards for life. He believed that since he had studied this major,
It's more or less a little bit dotted.
The morning light shone on the window. Zhang Yang glanced at the half-open curtains and couldn't help but swallow a mouthful of saliva. After all, Zhang Yang couldn't resist the temptation and gently walked to the curtains and opened them...
"Cha..."
"Cha..."
Zhang Yang was startled. He had just opened the curtains when a sound of curtains being drawn was heard from the building opposite. Logically speaking, Zhang Yang should not be able to hear it from such a distance, but he happened to hear it.
Zhang Yang hurriedly pulled the curtains closed and looked through the gap. He saw that the curtains in the dormitory building behind him were all closed, and many curtains were still swinging. Obviously, they were closed just now...
I couldn't help but feel depressed. Such nice weather was a good day for peeping, but I knew that because I did something stupid, I couldn't see anything.
"Brother, don't bother, as long as there is a slight movement of the curtains on our side, they will be closed on the other side." Zhang Yang's roommate on the upper bunk stretched his head and said.
"Ah...ahem...no...I just want to get some air..." Zhang Yang said awkwardly.
"Zhang Yang, we also want to ventilate, but now even ventilating is suspected, so we should keep the curtains closed. If you want to see, it's the same if you look through the crack. Don't worry, we won't tell the truth...
..." Another roommate also stuck his head out.
"..." Zhang Yang was speechless.
"Zhang Yang, we have lived together for a few years. No one blamed you for what happened. It's just that we always have a question to ask you." Another guy showed his head from the bed.
"Well?" Zhang Yang secretly thought that something was wrong, but he had to bite the bullet and say it.
"Why did you post those photos on the Internet? It would be great for us brothers to see them in the dormitory. Hey..." The roommate who spoke had a look of deep regret.
"That, that... you guys talk, I have to go to class, and I have to prepare. As you know, the preparation for our profession takes a long time..."
Zhang Yang fled in despair.
Zhang Yang spent this morning in the studio, boringly painting some plaster heads, and finally painted a pair of watercolors before leaving the studio. After lunch, he went straight to the library.
The library was deserted. Zhang Yang saw the old man again. The two nodded to each other and then immersed themselves in reading.
For Zhang Yang's introverted personality, he doesn't like social activities at all. What's more, the old man seems too old and is not the person he socializes with.
This time, Zhang Yang brought pen and paper. Every time he picked up a library book, he had the desire to do calculations on it.
Time passes slowly, and Zhang Yang's speed is still ridiculously fast. It is difficult for him to change a book for more than half an hour. Occasionally when he encounters a problem, he will pause, pick up the pen and make a few gestures.
Zhang Yang's interests are becoming more and more extensive, including proportional analysis, algebraic methods, logical methods, ordinary differential equations, fluid mechanics... He has begun to dabble in almost all subjects from design to mathematics.
Soon, Zhang Yang discovered that the books in the library could no longer satisfy his reading desire.
In fact, this school is just a low-end institution, and it has invested little in the library. Many books have not kept up with the times. Fortunately, the school has a long history, and there are still some materials. Otherwise, Zhang Yang would not be able to read it.
After all, Zhang Yang now has quite a wide range of reading options, and the scope of information books in many schools is also quite narrow.
At about five o'clock in the afternoon, Zhang Yang had lost interest in some mathematics books on the bookshelf, and began to wander around the library in various boredoms, trying to find some relevant information that he was interested in...
"Zhang Yang?"
"...Du Xue!"
While Zhang Yang was wandering around inside, a girlish voice came from behind. When Zhang Yang looked back, he saw that it was Du Xue.
"I'm sorry." When Du Xue saw Zhang Yang, she shook her clothes and lowered her head, her ears and neck turning red.
"Haha, it's okay. Do you also read?" Zhang Yang didn't want to dwell on that issue.
"Yes, I come here every day to read. I like this atmosphere... By the way, what books are you reading?" Du Xue breathed a sigh of relief when she saw that Zhang Yang didn't seem to take it seriously.
"There's nothing I like, I just browsed through it..."
Zhang Yang smiled and put the "Book of Mountains and Seas" in his hand on the bookshelf. He had read this book when he was very young and just flipped through it casually.
"What kind of books do you like to read?"
"I'm not interested in anything. I used to like reading online novels, but I've been busy lately so I haven't gone out."
"Ah... you also like to read online novels?" Du Xue looked excited.
"Well, just to kill time."
Looking at Du Xue's white and tender skin, Zhang Yang's heart beat for a while. Du Xue was the kind of girl who became more and more beautiful the more she looked at her. She was so soft and frail that it was easy for people to have a protective mentality. In fact, when on the train,
Zhang Yang's sudden burst of courage is also related to Du Xue's weak temperament. In every man's heart, there will be a subconscious desire to protect the weak machismo... [Recommendation vote is not fierce]
