At eight o'clock on Monday night, Yao Yayao came to Associate Professor Qian's teacher's apartment as promised. He had a few learning difficulties, and he wanted to ask Associate Professor Qian to solve them in person.

Associate Professor Qian's apartment space is still relatively large, with four bedrooms and two living rooms, and the decoration is elegant. Both rooms have clever bookshelves with a large number of books. This fully embodies the elegance of intellectuals.

Associate Professor Qian's family seems to have gone out for a walk, and he is the only one in the house. While making a large pot of tea to entertain Yao Yayao, he said slightly apologetically:

"Yayao, I've kept you waiting! On Saturdays and Sundays, I usually go out and work part-time, so I'm very busy and don't have time at all. If you want to come to me for anything, try to come over Monday through Friday nights. ”

Seeing that Yao Yayao seemed to show a little confused expression, Associate Professor Qian, who had half-gray hair, shook his head lightly, and said helplessly:

"The state is also not kind to us professors. The house is huge, and additionally a complimentary renovation. I could live here for the rest of my life if I wanted to. But they don't know that when people get old, they always want to be able to return to their roots. Now that the house outside is so expensive, with my ten-year salary, I can only buy half a living room when I return to my hometown. ”

"Although this teacher's apartment is very beautiful, you can't take it away and you can't buy or sell it. Therefore, teachers only go out on Saturdays and Sundays to work part-time to prepare for the future of retirement in their later years. ”

With such a heavy topic, Yao Yayao didn't know what to say. Therefore, he could only nod his head again and again, indicating that he understood.

After a casual exchange of pleasantries, the conversation began. Yao Yayao spread out the book he brought, and asked Associate Professor Qian for advice on the difficult parts of the book that he had made special marks.

The professor is really the level of the professor, and what Yao Yayao has learned is not confused, and when it comes to Associate Professor Qian, it is all easy to solve.

"The cross-sectional stress calculation of the parabolic arch axis of this three-hinged arch is also valid for your solution. The reason why this simplified solution idea is not mentioned in the textbook is that it needs to involve a special formula for the differential commutation integral method: ∫x^αdx=x^(α+1)/(α+1)+C. ”

"It will be difficult for the average college student to fully understand this particular formula. College textbooks focus on popularization and acceptance, so the book prefers to choose another method of solving the problem that is cumbersome in the process but easy to understand in the reasoning steps. Advanced mathematics is a course that many ordinary college students in universities will inevitably fail at the end of the semester, so it is better to avoid the light than the heavy. You're good at advanced math, so you'll be able to think of other ways of solving problems. ”

"As for the fracture mechanism of the creep along the crystal of the metal material folding, you simply rely on the text description, and naturally you cannot intuitively understand the material distortion process at the critical point of decay. I have here a dedicated in-house laboratory atlas with a local 5,000x magnification of the material's molecules taken with a high-speed camera. For example, the differences in materials between carbon-containing alloy steels and non-carbon-free steels are clear in the local details in the atlas. ”

"I can borrow this atlas and take it back to the dormitory. Be cautious and don't lose it! This is an exclusive atlas of the school's labs, which is only available to teachers in the school, and cannot be purchased outside. ”

Associate Professor Qian patiently answered all of Yao Yayao's incurable diseases.

While answering the question, his face also showed a slightly surprised expression, but Yao Yayao was so immersed in the ocean of knowledge that he didn't notice the expression on Associate Professor Qian's face.

Associate Professor Qian was surprised because he felt that these questions should not be asked by a first-year student, especially a student who has just entered the school for two months. If a junior comes to him and asks him about these questions, it seems normal.

Associate Professor Qian has been teaching at Xiannan University of Technology for many years. A student like Yao Yayao, who has a high degree of initiative and subjectivity in learning, has not seen it for many years. Ordinary college students can complete the prescribed textbooks in the school, and if they don't fail the final exam, they are already very good.

"Sure enough, interest is the best teacher!" Associate Professor Qian sighed in his heart. Combined with the strange consulting questions that Yao Yayao asked him in the classroom last time, he found that almost all the questions asked by Yao Yayao tonight were related to the 922 building collapse incident.

Yao Yayao, a freshman who has just entered the school, is because of the book "The Great Scam of the 922 Shocking Century", and now he is persevering in pursuing all kinds of relevant knowledge in the book, and then continues to study and research?!

His own students actually have a very hard work spirit in learning, and this unexpected discovery made Associate Professor Qian suddenly feel a little relieved.

However, there are pros and cons to everything, and it is not a good thing to pursue the truth too much and seek scientific truth. People who have too much scientific research spirit are often the people who are most likely to "hit the thunder" and step into misunderstandings.

For example, Copernicus, who was the first to propose the "heliocentric theory" instead of the "geocentric theory" and then burned at the stake, is the most typical example.

While answering Yao Yayao's questions fluently, Associate Professor Qian was also groaning, thinking about how to guide studious students like Yao Yayao.

Yao Yayao knew nothing about Associate Professor Qian's inner activities. He quickly raised one of his major doubts:

"Professor Qian, why was Building 6 of the World Trade Tower, another 47-storey semi-skyscraper, not hit by a plane at all, and then the whole building collapsed? Official sources say it was also caused by the fire. The building was not made of wood, so how could a fire burn with such serious consequences? ”

The freshman in front of me is really curious! Associate Professor Qian sighed in his heart.

There are countless cats in this world, all of which are ruthlessly killed by curiosity!!

Associate Professor Qian made up his mind to tell Yao Yayao about the truth of life. Otherwise, this good seedling in front of him may go astray in the future and suffer some unexpected injuries that should not be suffered.

It is good for a person to have a more sincere spirit, but it depends on what kind of environment he is in. Sometimes, "If you're serious, you've already lost!" ”

"Yayao, have you ever heard of the term 'suicide'? The reason why Building No. 6 completely collapsed in six or seven seconds is probably because it was "collapsed", or "collapsed in fear of sin"! Associate Professor Qian said lightly, and the corners of his mouth actually revealed a hint of cynicism that high-level intellectuals should not have.

"Suicide?? Collapsed?? Yao Yayao's expression was stunned. At his young age, these two sarcastic terms were obviously beyond his comprehension.

"Come on, don't worry about how this building collapsed. The teacher now wants to talk to you about a book, Mr. Quan Yong's famous martial arts book "The Seven Divisions of the Heavenly Dragon", have you read this book? ”

Associate Professor Qian stood up and ripped off a book on a small bookshelf in the living room. It is the "Seven Divisions of the Heavenly Dragon" that he mentioned.

"Yes." Yao Yayao nodded. He didn't quite understand what Associate Professor Qian meant when he suddenly mentioned this martial arts book.
