Chapter 7 Late Feedback
On the hill behind Yichuan Academy, from the top of the mountain to the slope at the foot of the mountain, there is a core and elite of Luoxue standing at intervals, and at the foot of the mountain, Cheng Yi's eyes squinted at the top of the mountain.
"Teacher, they seem to be ready. ”
"I saw it. Cheng Yi looked at the stone ball rolling down from the top of the mountain, and what came to his mind was the experiment mentioned in Qin Xianao's article "Talk".
"Since Qin Xianao has come to a conclusion, he should not be wrong. Cheng Yi thought about it, the stone ball rumbled in front of him, and Yang Shilian stretched out his foot and stepped on the stone ball.
"Count!" Yang Shi shouted.
"I'm 20 here!"
“27!”
“35!”...... One by one, everyone's eyes lit up.
"Teacher, sure enough, objects keep getting faster when they fall in the air. "Teacher, it seems that Qin Xianao and Duan Haifeng's acceleration formula is not wrong. Said excitedly one by one. Cheng Yi nodded slightly: "Continue to the next one!" "Yes!" A group of people rushed to the eastern forest.
"Master, Qin Xianao has done these experiments, we actually ......," Luo Congyan said in a low voice.
Cheng Yi raised his eyebrows: "Zhong Su, this experiment is not to verify Qin Xianao's conclusion. "Isn't it a verification conclusion?" Luo Congyan looked at Cheng Yi suspiciously, Cheng Yi smiled indifferently and strode forward. "Zhong Su, you should carefully read Qin Xianao's new book. Yang Shi smiled. Luo Congyan's brows furrowed.
"Zhong Su, Qin Xianao's new book, the most valuable thing is not the theory in it, but the way of doing research, this way, we ourselves understand that it can't work, because our strength is limited after all, so cultivating future disciples and cultivating good research methods is what the teacher values the most. You Xing said in a low voice.
In the courtyard of the Prime Minister's Mansion in Bianliang, Sima Guang grabbed an iron ball with both hands on his left and right, and raised it thirty zhang high. Then he raised his hands flat and released them at the same time, and suddenly the two iron balls, one large and one small, fell to the ground.
"Canopy!"
The iron ball lands.
"Those who landed at the same time, sure enough, landed at the same time. As soon as Sima Guang's feet hit the ground, he laughed loudly and walked into the study.
In the garden, an eighteen-year-old woman sits on a swing. The old man behind him gave him a push, then jumped to the side and watched the swing swing swing back and forth.
"My grandfather is really, in order to verify the experiment in Qin Xianao's book, he actually let me ......" Zhao Ming'er was full of helplessness, she is now a young girl, where can she play on a swing, but grandpa's order, can she not obey?
As soon as the swing goes up and down, the swing amplitude becomes smaller and smaller. It gradually stopped.
"Haha!" Zhao Ting let out a haha and left with his hands behind his back.
......
In a study room in Qingfeng Manor, Qin Chao looked at the book "Conversation" in his hand.
"No problem, why hasn't anyone reported it so far?" Come in!" Qin Chao looked at the door. "Tent!" Abi pushed open the door heavily, "Childe, here, here!"
"You mean...... Qin Chao's eyes fell on Abi holding a dozen telegrams, and his heart was pounding.
"You can see it when you look at it. Ah Bi put the draft of the telegram in his arms on the table in front of Qin Chao. Smile so much that his face was red, "Childe." Look, the telegram is still ringing over there, and there's still a lot of paper!" he said and rushed out of the study door.
The Qin Dynasty directly opened a telegram draft.
"Qin Xianao's writings never disappoint, this is already the consensus of the world, so when I got this book, I also had high expectations......
Qin Chao's heart skipped a beat. It can't be a bad word, right?
Undoubtedly, the title of this book is contrary to Qin Xianao's previous thickness, although this is a bit surprising, but considering that this book is written by Qin Gongzi, Duan Haifeng, and Qin Xianhao's "Dialogue". It's nothing, open the book, the preface is very well written, these don't need to be mentioned, if Qin Xianao doesn't have this foundation, he is not Qin Xianao!"
"When you read the text, it is also unexpected and reasonable, and the way of writing the text is completely a simulation of Duan Haifeng and Qin Xianhao's book "Dialogue", but the characters of the dialogue have become Duan Haifeng and Shen Kuo, and Qin Xianhao is secondary. ”
In the book "Dialogue", Qin Xianao is a clown-like character in the book, highlighting and praising Mr. Liu Qin, while this "Conversation" is Duan Haifeng becoming a clown-like character, highlighting and praising Shen Cunzhong. ”
"Shen Cunzhong has had a bumpy career in his life, and he has done some very shameful things, so at first glance, when I read that Shen Cunzhong has become the positive protagonist in the book, I am a little uncomfortable, I think most readers in the world are probably not adaptable, but if you think about it carefully, Shen Cunzhong's cultivation may have some problems, but his knowledge is excellent, so Qin Gongzi let him play a positive role in the book, and he is also passable, I will not say more here. ”
"It is undoubtedly very interesting to adopt a style similar to the book "Dialogue", and Qin Gongzi is skillful in writing, and the dialogue of the characters in this book is obviously higher than Duan Haifeng and Qin Xianhao's "Dialogue" in some aspects such as interesting, easy to read, and literary. ”
This kind of book is very attractive, especially for ordinary readers, but for people in our industry, the value of reading a book is not literary, let alone interesting, but the value of the Tao it contains, so I pay more attention to the substance of the narrative in the book, so I read it with both skepticism and expectation. ”
"This book talks about the way of nature, in short, it is mainly motion and mechanics, motion and force are the most common and commonplace in life, but to tell the truth, it is also the most difficult to convince, but I never thought that Qin Gongzi's book would be so powerful......"
Qin Chao's pounding mood calmed down suddenly.
"From the first example in the book, I can't help but fall into it, there is no doubt that Qin Xianao's analysis of the operation of various mechanics is very accurate and appropriate, but I am more interested in the example evidence on which his analysis is based......"
This article is full of praise and some questions to ponder and ask.
After reading this one, Qin Chao looked at another manuscript.
"Just as we regard the book "Dialogue" as an upgraded version of "The Theory of the Movement of Celestial Bodies", now I can say that this "Dialogue" can be regarded as an upgraded version of "Dialogue" if we do not take into account the astronomical system......"
This is also an article that gives high praise to the book "The Conversation", and then-
"The old man Cheng Yi can make a prediction here, a broad and profound science has been enlightened, and the work of "The Conversation" in this regard is only the beginning of it......"
"In the last book of Duan Haifeng and Qin Xianhao's "Dialogue", we can see the signs of the germination of some mechanical knowledge in it, and this one has really sent out tender shoots and grown new leaves......"
"After reading this book, I can be sure that a new science has been born, and that is the ...... mechanics"
"The discussion of the motion of free fall, inclined plane, throwing object, and pendulum in the book allows us to see the direction of mechanics research......"
"The dog Sima Kang attaches great importance to the study of kinematics in the book, but the old man values the experimental methods, idealized methods, eloquent reasoning and strict mathematical deduction methods in the book, etc., which is definitely the beginning of a new era in physics......"
"A genius is a genius, and the oblique rollerball experiment in the book, like the last hemispheric experiment, is definitely a classic experiment in the history of science......"
......
An article, either from Cheng Yi, or Sima Guang, or by Lu Gong, or by Wang Anshi...... In addition to discussing some of the scientific issues in the book, it is also full of praise.
Soon after Qin Chao finished reading the telegram draft on the table, Ah Bi rushed in with a dozen telegram drafts: "Childe, these are the same, you watch first, I'll go to the telegram room." ”
"Put it aside!" Qin Chao stood up and walked out of the courtyard.
Galileo was the pioneer of mechanics, but to lay the foundation, Newton, Descartes and other scientists of his time were needed. Qin Chao looked at the sky, his eyes flashed, "Now that the research of mechanics has begun, the next ......" Soon Qin Chao walked into the study, picked up the pen, and soon lines of numbers and formulas appeared on the paper.
Science can be expressed in numbers, and the knowledge of planets and celestial bodies must also be demonstrated by mathematical logic, and only when the calculations are consistent with actual observations can they be truly convincing.
Kepler's three laws of planetary motion are simple to say, but they are the product of Kepler's long and complicated calculations and countless failures throughout his life.
"I know Kepler's three laws, but I haven't read his mathematical argumentation process at all. A trace of helplessness flashed in Qin Chao's eyes, although there was a lot of information in his mind, but in his previous life, after all, he majored in liberal arts, not a professional scientific researcher, and in terms of science, he knew everything about the definition and formula of big theorems such as Kepler's three laws, Newton's various laws, and gravitation.
However, in terms of details, the mathematical calculation of these formulas is a step lower. In particular, when Newton and Kepler came up with their classic three laws of planetary motion, the laws of gravitation, etc., how to fail again and again, fill in the loopholes again and again, and finally use mathematics to calculate, these are completely blank.
"Fortunately, I was not a partial subject in my previous life. ”
The formulas of his previous life flashed in Qin Chao's mind, and at the same time, he deduced and calculated them against the data of various stars such as the moon, gold, wood, water, fire, and earth observed with a telescope.
Although the Qin Dynasty can directly prove it with the longevity formula, this is not a real scientific attitude at all.
And the Qin Dynasty also had confidence.
"Kepler spent his whole life and Newton spent decades figuring out those theorems, but they didn't know the answers, and now I have the answers, the data, and I want the process of reasoning. "In the study, the Qin Dynasty sometimes moves like a fly, and sometimes meditates with a deep face. (To be continued.) )
