Qingfeng Manor Bamboo Garden is inside.

"The knowledge of geometry and mathematics in this book is still good, and some of the first content is barely acceptable, but since this theory of relativity, the latter one is more absurd than the other. ”

"Special relativity is unreliable, general relativity is even more crazy and irrational, and quantum theory is even more unacceptable. ”

......

Su Shi, Cheng Yi, Shen Du, Li Kefei and others quarreled and discussed from time to time, and after reading this book "New Physics Foundation", everyone was puzzled and waited for Qin Xianao to return, so as to ask, this day of waiting for Qin Xianao naturally discussed the arguments in the book.

"Click~"

The door opens.

"Others are not shocking and endless, but this Qin boy is not shocking and endless. Su Shi rubbed his head and walked out of the house, walking out of the corridor, for Su Shi, visiting the Qingfeng Manor of the Qin Dynasty is like visiting his own yard, there is no big scruples, and these days Su Shi has already read "New Physics Foundation" has already made Su Shi dizzy.

Su Shi walked along the mountain road outside Qingfeng Manor.

"Qin boy is really, he is hiding at this time, won't he go to Qin's village?" Su Shi squinted, and suddenly his ears moved, and several children not far away were playing at home.

"Mr. Qin caught a basket of yellow eels, I didn't believe it, my father and mother said that Mr. Qin was a scholar and never went to the field. ”

"What does your father know, my father accompanied me yesterday to catch yellow eels in the hill field of Huangniwan, my father is a scholar, but he catches loaches, and yellow eels are stronger than your father. A crisp sound rang out.

"It was Qin Ben who spoke. Su Shi's eyebrows and heart beat, "This Qin Ben kid said that his father was here to catch yellow eels yesterday, which doesn't mean that Qin kid didn't stay away at all." At this thought, Su Shi even walked to a few children: "Ben'er, Yuan'er, does your father really know how to catch yellow eels......

"Hey, it's Uncle Su!" ......

Su Shi teased a few children, Qin Ben and Qin Yuan are children after all, even if the Qin Dynasty explained that they were not allowed to reveal the news of the Qin Dynasty to Su Shi, Cheng Yi and others, Su Shi could wipe his feet with a few words, and then he set out the location of the Qin Dynasty.

There is a small valley planted with various medicinal herbs in Qingfeng Gorge, and there is a manor 'Baicao Garden' built next to the medicine field, which is the residence of Yuwen Rouniang.

"Sheng Chao, are you really going to retreat?"

"No, no, the "New Physics Foundation" I released this time, after all, it was released a little early, and there are not many people in the world who can understand and agree with it after all, and only by demonstrating it as soon as possible from the longevity formula can it be recognized. Qin Chao looked at Yuwen Rouniang and Li Qingzhao who were drying medicine in the courtyard. Among the women, Li Qingzhao and Yuwen Rouniang are the most compatible, and Yuwen Rouniang studies pharmacology and biology, and Li Qingzhao also studies botany and genetics, these two disciplines are intersecting, so the two have a lot of topics.

"I don't know if it's right or wrong in your book. Li Qingzhao hung an angelica on the rope, and suddenly her hand stiffened slightly, and her eyes looked into the distance: "Sheng Chao, hide quickly, it seems that they are coming." ”

"I can't hide, they should have gotten the news from your mother and made a special trip to surround me. Qin Chao stepped forward to help Li Qingzhao sort out the angelica. Soon, figures appeared in all directions.

"Brother Qin, what a grace!"

"Qin Gongzi, you are really a noble person. ”

"Accompanied by beautiful women, Qin Gongzi is really 'busy'!" Su Shi, Shen Du, Dong Xiyan, Cheng Yi, and Li Kefei flew down in front of Qin Chao, and Wang Yixian also flew into the courtyard with a smile, glancing at Qin Chao with beautiful eyes: "Qin Gongzi, I didn't reveal your whereabouts, it was Mr. Su who found you." ”

Qin Chao shrugged his shoulders and walked towards the lobby: "Since you are here, please serve tea inside." ”

"Qin Gongzi, we are not here to drink tea, but to ask you a few questions, I will ask you. Cheng Yi glared at the Qin Dynasty, and his voice was like a bell, "In your book, the special theory of relativity puts forward a premise that 'the speed of light does not change', I want to ask, how did you arrive at this premise that obviously violates normal rules?"

"Light is a wave, and it is also a particle. Shen Du pointed directly to the stream next to him, "The light wave is no different from the water wave, you see that this stream flows on the flat ground and on the steep mountain, and the flow speed in the river and the waterfall is the same?"

"The earth movement theory has now proved that the earth moves around the sun, the earth rotates, and light will inevitably be fast and slow in the aetheric storm, why do you think that the speed of light does not change?" Dong Xi said crisply.

Qin Chao smiled bitterly in his heart, for many phenomena of optics, this era also appeared to describe the name 'ether', although the invention of 'ether' to describe some special phenomena, but at this time the development of science and technology has not yet reached the level of the later Michelson-Morey experiment, and it is naturally impossible to find out the wrong thing about the 'ether' theory.

"Ladies and gentlemen, the constant speed of light is an assumption. Qin Chao said.

"Hypothesis?" Cheng Yi's voice became louder and louder, "You yourself have always said that science is rigorous, and you can't come to all kinds of hypothetical fantasies that are out of tune, why do you set up a hypothesis here?"

"I admit that there is really no conclusive experimental evidence here, not even a hundred or even five hundred years from here. Qin Chaolian said that the invariance of the speed of light and the principle of relativity are the two logical premises of the special theory of relativity, and the speed of light is unchanged, even in the era of the Qin Dynasty's previous life, there is still no convincing conclusive evidence, and there is even some evidence that the speed of light is also variable.

"Qin Gongzi, it's good that you can admit this, but why?" Cheng Yi spat out.

"Because there's no other way. Qin Chao raised his eyebrows, "If you want to give physical meaning to the concept of time, you need some kind of process that can establish the relationship between different places. For such a definition of time, it is not important which process is chosen, but for the sake of theory, I can only choose the one that seems to me to be more understood, more clear and reliable, and the propagation of light in a vacuum seems to me to be the best one at present. ”

"No science can make assumptions, even if light travels. Shen Du interjected, "What you call the definition of time is a clock paradox. ”

"Qin Gongzi, everything deduced from your two premises looks good, but it is too complicated and does not meet the simple aesthetic definition. Dong Xiyan smiled, "Qin Gongzi, according to the inference of your theory of relativity, the time of moving objects has slowed down. ”

In other words, there are two brothers, the elder brother flew out of the earth to travel at the speed of light, and returned to Earth a year later, and his younger brother is already old. But everything is relative, people sit on the boat, what they see is the trees on the shore moving, not themselves, the elder brother flew out of the earth to travel at the speed of light, in the eyes of the elder brother, the earth is also moving at close to the speed of light, so he returned to the earth after sixty years, and it was only he who became old, and the earth was only a year later, and it was not necessarily. ”

"One day above the heavens, a thousand years in the world, or one day above the world, a thousand years in the heavens. Li Kefei sat down on the side, his eyes shimmering at the Qin Dynasty.

This is not a paradox. Qin Chao shook his head and said, "Whoever is a thousand years, who has a day depends on the mass energy between them, the sun around the earth and the earth around the sun, is it relative? The mass of the earth is smaller than that of the sun, so the earth surrounds the sun, not the sun around the earth, so this time paradox does not exist at all." ”

"Young Master Qin, you haven't explained the matter of the ether to me yet. Dong Xi looked at the Qin Dynasty with a smile.

"The so-called ether is just a kind of thing that everyone has imagined, and I don't think it exists......"

"If the aether doesn't exist, how do you explain those phenomena, and how do you come to the ...... that the aether doesn't exist?"

"Aether, like heat and oxygen, is a kind of substance that is forcibly constructed because we don't know enough about natural science......

......

Time passed, and the Qin Dynasty continued to explain their doubts to Cheng Yi, Shen Du, Dong Xiyan, and Li Kefei, but after all, the assumptions of the theory of relativity were too 'absurd', and the various phenomena deduced were too unimaginable and unacceptable, so in the end, they were still not convinced and did not recognize this "New Physics Foundation".

It's getting late.

"Ladies and gentlemen, what I want to say has been written in the book, and what has not been written in the book is because the conditions are not enough, and everything should be left to practice to prove in the future. Qin Chao smiled bitterly.

"That's fine. Cheng Yi grabbed the teacup on the table and drank it all.

"It seems that Qin Gongzi, your theories are indeed too fanciful and not rigorous enough, so you can only let them go first. Shen Du nodded, after all, if he asked, it would be impossible for the Qin Dynasty to convince them.

"Haha, Brother Qin, they don't ask, I have a question. Su Shi said loudly.

A pair of eyes looked at Su Shi, all day long, Cheng Yi, Shen Du, Dong Xiyan, and Li Kefei turned to the Qin Dynasty to fire, but Su Shi and Wang Yixian just watched the play from the sidelines.

"Speak. The Qin Dynasty was also curious about Su Shi's question.

"In this book, you use the special theory of relativity to derive a formula called the 'mass-energy formula'. Su Shi said loudly, "You wrote a sentence after this formula, 'If my expectation is correct, this is a devil's formula', I'm curious, why do you say this formula is the devil?"

"Mass energy formula?" Qin Chao's heart jumped.

The mass-energy formula derived from the special theory of relativity, that is, the one E=MC?, this one seems to be a beautiful, concise, and beautiful formula, which is very famous in later generations, but the Qin Dynasty wrote that he is the formula of the 'devil', mainly because this formula explains the principle of the atomic bomb.

Cheng Yi, Shen Du, Dong Xiyan, Li Kefei, and Wang Yixian actually saw the inexplicable sentence of 'this is a devil's formula', although they were puzzled at the time, but because the relationship between mass and energy revealed by the mass-energy formula itself is incredible, so everyone didn't think much about it.
