Chapter 62： Underestimated the ancients
Afterwards, Wu Changqing asked to distribute the printed book "Elementary Physics" and exhorted: "This book is extremely precious, I hope you can take good care of it. At the same time, please take a look at yourself first. If you have any questions, the class will officially start tomorrow. Ask me questions at time."
Feng Xianzhong and Liu Tao were like treasures when they got this book. Their future official movements are all in this booklet.
The others are the same, put them carefully.
Wu Changqing talked about some other points for attention, and then left first. He still had many important things waiting to deal with decision-making.
Some of the other students go home, while others live in the dormitory in the university hall.
Feng Xianzhong and Liu Tao are both from Suzhou and both live in houses in the city. But in order to implement the spirit of hard study and not waste time on the road, they also live in the student dormitory.
Back in the dormitory, Feng Xianzhong eagerly opened this elementary physics book.
The first page is a table of contents, which reads mechanical motion, sound phenomena, changes in physical state, light phenomena, mass and density...
There are so many new words that Feng Xianzhong is at a loss.
He knows the meaning of movement, but what is mechanical movement?
He could understand the sound phenomenon literally, but he couldn't figure out what other common sense of sound could be learned, and what use could he learn?
After a brief look at the table of contents, he began to read the text.
Junior high school physics is not easy for children to understand, but for adults like Feng Xianzhong, it is actually easy to understand.
It's just that there are many new terms in the book, and it is difficult for him to adapt for a while.
Looking at it, Feng Xianzhong was fascinated by it. Human beings are always full of curiosity about the unknown, and the content of this book has always been revealing common phenomena in life, which is very interesting.
"It turns out that the sound is spread like this. But how do you prove what is said in this book?"
Feng Xianzhong muttered to himself.
This set of junior high school physics written by Wu Changqing is quite different from what he used in school before. Many things have been deleted and other things have been added.
For example, the unit of length, he has to redefine the unit of meter. You know, the length unit used in the Ming Dynasty is still in feet, and Wu Changqing is not used to it.
Most of the knowledge in the book is just a simple conclusion, without explaining how to verify it. For example, sound is transmitted through the air. This Wu Changqing has no way to verify. He can only tell the students that it is transmitted in this way.
There is no other way. To impart such knowledge in this era is indeed too radical.
"Brother Feng, you may understand what is written in this book?"
Liu Tao looked miserable. He was watching it just now, but he looked dazed.
"Generally I can understand, but there are also many questions."
Feng Xianzhong said.
After all, geniuses like Feng Xianzhong are in the minority, and most of the scholars who have read textbooks are eager to cry without tears. They found that the official position in Wu Changqing's hands was not so easy to take.
The next day, the first physics class in the university.
Wu Changqing took some rulers and walked over with a prism. At this moment, wherever he had the image of a general, he was just like a people's teacher, just a pair of glasses.
"Physics, the principle of all things. Why do heavy objects fall from the sky, but the moon and the sun do not? Why do we often see lightning first and then hear thunder? Why do you light the gunpowder and the bullets in the blunderbuss Shoot a hundred meters away?
The physics we are learning is to unravel the principle of the operation of everything in this world. "
Wu Changqing said vigorously, in front of these ancient people, his sense of superiority was overwhelming, because he knew so much better than others.
Unraveling the truth of everything, the tone was quite loud, and some students were full of enthusiasm when they heard it.
"After you went back to read the books yesterday, did you gain something, do you have any questions?"
Wu Changqing asked.
Feng Xianzhong immediately raised his hand. This is the rule Wu Changqing said yesterday. You need to raise your hand before asking questions.
He is very eager to show himself in front of Wu Changqing and show his talents. Only in this way can it be easier to be recruited as staff.
Wu Changqing motioned for him to say, Feng Xianzhong stood up and said: "After reading the book, I learned that because the speed of light is faster than sound, we will see lightning first and then hear thunder. It's just that, What I don’t understand is why light is faster than sound, how much faster."
"..."
Wu Changqing was almost dumbfounded. He found that he seemed to underestimate the IQ of the ancients. This person who answered the question was quite remarkable, at least with a very strong memory.
In just one day, I had read the acoustic part and the optical part, and I remembered them all.
Wu Changqing knew that he had encountered a legendary genius. Comparing IQ with this kind of genius is a very silly behavior, and Wu Changqing didn't do it.
Anyway, no matter how smart this person is, he is still only his student now.
Wu Changqing opened the mouth and said: "The answer is very good. It seems that you read the book carefully. As for why the light you said is faster than the sound, this teacher is not clear. I can only tell you what I know. As for why light is faster than sound, this teacher is waiting for you to be better than blue, and wait for you to crack."
It's not that Wu Changqing really doesn't know why light travels faster than sound, but it is too complicated to explain. In teaching this stuff, we still have to proceed step by step, starting from the simple.
Now telling them about the loss of power in the transmission of sound waves, that is undoubtedly talking about the heavenly book. Even Wu Changqing himself is not very clear about this part of knowledge.
Feng Xianzhong was a little excited after receiving Wu Changqing's praise. No matter how young Wu Changqing is, he is still an upright second-grade member, Wu Guogong.
It is an exciting thing to be recognized and praised by such characters.
Others cast all kinds of envy, jealousy and hatred. Feng Xianzhong was already ahead of them.
Although they don't think there is any use in knowing that light travels faster than sound, they can be appreciated and praised by Wu Changqing, which means that they will be able to be officials in the future.
Since then, some people who have read the book and have a little bit of money also raised their hands cautiously and said some of their own thoughts and questions.
This is Wu Changqing's first batch of students, and he answered very patiently. Basically every question, he will use easy-to-understand words to explain.
As for some things that he couldn't explain clearly, or were too advanced, he said that he would talk about it later, and now start with the simple ones.
The first class teaches mechanics, which is a very basic and practical knowledge point. After a lesson, most students understood it, but there were also a small number of people who couldn't understand it.
There is nothing for this group of people to understand. Wu Changqing doesn't have so much time for counseling.
His identity is destined that he can only teach some geniuses, and ordinary people certainly can't keep up with him.
