[Group Wearing Song Dynasty] The Glory of the Sky

"A humanist who knows nothing about thermodynamics is as bad as a scientist who knows nothing about Shakespeare." - Charles Percy Snow, Two Cultures and the Scientific Revolution

Xin Qiji felt that his breathing stopped for a few seconds.

He went from an ancient man who only knew the Four Books and Five Classics, to an intern at the Linguo Senate, to a teacher at Wensi Academy, and then to a student at Jiangyin Middle School. This series of identity changes and self-cognition changes all happened in the In less than two years.

He couldn't even imagine what he would become in five years.

And now, sitting next to Yuanshou Liu who started to crunch beans again, he stopped breathing for a few seconds because of something that he couldn't touch at all.

"It's not a serious question. This concept is like explaining why the sun is red—" Liu Xi comforted, "Calm down."

Wait...why is the sun red?

Xin Qiji felt that after opening his eyes, sooner or later he would be trapped by infinite questions, so he chewed over and over again: "You mean, the essence of time is the change of matter?"

"Further down, we will talk about entropy increase and other aspects of knowledge." Liu Xi signaled him to bring some beans, raised his eyebrows and said, "That's not something that can be finished in three or four days."

"Besides, I don't quite understand the mysteries of it." Liu Xi shook the finger on his thumb and explained: "My family did engage in this industry in the past time and space, but I haven't had much contact with physics and related fields. In fact, he is also a layman."

But what he said was shocking enough.

If time is the movement of matter and the transmission of energy, then in order to reverse time or affect time, the essence is to study the relationship between energy and matter—

"But having said that, maybe in a few decades, by 2060 or even earlier, the mechanism of time and space and other things will have been deciphered clearly." Liu Xi interrupted his aimless thoughts, raised Picking up the mobile phone at hand: "How long do you think it took for this thing to flourish from birth to prosperity?"

This is a smartphone.

Xin Qiji has long experienced the [-] uses of this thing that are no less than that of a tablet, and has even long since gotten used to its existence in his own life—of course, this thing is still mysterious and daunting to Song people. artifact.

"Hundreds of years?" He asked uncertainly: "The structure of this thing is too precise, I have taken it apart and seen it..."

But he couldn't understand the mechanism inside, and the screen that could change into various pictures.

The birth of this kind of thing is not like a steamed bun in a pot that can be steamed out in one go.

Every component is a product of modern industry, the slimmer and more convenient it is, the more hidden beauty it has.

"Wrong answer," Liu Xi laughed: "As a communication tool, it took decades to evolve."

"It took less than ten years to evolve from a communication tool to a multi-functional terminal."

Xin Qiji's eyes widened suddenly, he clenched the cold cell phone, and subconsciously looked around: "In less than ten years—has it changed like this in less than ten years?!"

"The development of science and technology is not about building the Great Wall. It is not about building the Great Wall brick by brick. It is not considered complete until the last brick is built." Liu Zi said slowly: "On the contrary, it is more like tearing down obstacles."

People set up various research groups to constantly eliminate wrong choices and research models, just like a group of people surrounded by building blocks, waiting to remove the core piece, so that the entire obstacle collapses.

"The wrong options that were dismantled before are of course of reference." He said meaningfully: "But as long as someone intentionally or unintentionally pries open the most core piece, all obstacles will be dismantled head-on.

Xin Qiji had seen the Lego blocks in Qingyu's room, but he still didn't quite understand what he was talking about.

"Can you make it more clear?"

It seems that he doesn't worry about being late for class if he doesn't wake up.

Liu Xi thought he had another reason to sleep in, so he turned on the phone with facial recognition, and showed him the signal notification on the upper right corner of the phone.

"5G signal, 4G signal, can you see this mark?"

The rapid development of mobile phones lies in the fact that someone has figured out the data transmission mode.

From 1983 to 1991, signal transmission developed from 1G analog cellular network to 2G digital network.

From 1991 to 2001, it developed from 2G to IP data network, and packet switching replaced circuit switching, which is a milestone in mobile communication technology.

From 2001 to 2009, the 4G network era of all-IP data came, circuit switching completely disappeared, and communication costs dropped significantly.

It is as if the core load-bearing part of the building blocks is continuously removed, and finally all the shackles are disintegrated.

"I'm not saying this to tell you how mobile phones were developed," Liu Zi said seriously, "Such things can also be substituted into the history of physics or even any other discipline."

When a certain joint is opened, things will change from quantitative to qualitative.

The definitions of thermodynamics and quantum mechanics in physics are too complicated. Not to mention explaining to Xin Qiji, even he himself is sometimes confused, but certain objective laws are like this.

People may argue or study for thousands of years for definitions and derivative theories such as time and space, but it may only take a few decades or even less to really play a key role.

"You mean, the technology of quantum teleportation is also such a... building block?" Xin Qiji asked suddenly: "In this case, could someone have already removed the core of the building block, but didn't tell you?"

Will someone have already mastered the technology of living body teleportation or even teleportation across time and space?

This is a very bold assumption, but according to his own sources, it is unlikely.

Liu Xi chuckled, waved his hands and said, "Then I'll ask the Bodhisattva."

Yangzhou City.

Sun Ci glanced at the time, thinking that bastard Liu Xi must have fallen asleep again, and he hadn't returned to Jiangyin City for the meeting at this point.

She glanced at Long Mu who was waiting next to her, showing a rather apologetic expression: "I'm sorry, I might have to wait a little longer—how about you go to the meeting room next to me and wait?"

Song Guo's delegation came a little earlier, so she couldn't be busy at all.

Didn't it arrive just after the explanation? !

There was nothing important about Long Mu, he just nodded and went to the meeting room next to him, continuing to read the unfinished documents.

His life is boring and monotonous, but he has long been used to these things.

The door was opened gently.

He raised his head and saw a woman dressed in Song Dynasty standing at the door, as if confirming his appearance.

"Hello?" He put down the tablet, took a few steps forward, looked at the young woman and asked, "Are you going the wrong way? Do you need my help?"

This happened many times.

Long Mu had stayed in the Senate for a period of time before, and received requests for help from various people almost every two or three days.

Some just came to the Senate Council to do business and went to the wrong floor and room, some had disasters of all sizes at home, and some came here with the mentality of seeking gods and Buddhas and simply wanted to burn incense sticks for the people of Linguo.

Although the guards have always been in charge, most people have a reason to be able to enter the Senate.

Although he doesn't have much time, but out of kindness, he will always help out when he can.

The woman took a step back subconsciously, but her eyes were still fixed on herself.

She looks very good-looking, even if she doesn't wear any gorgeous makeup, she has a completely different temperament from others just because of her facial features.

Long Mu felt that her emotions were not right, so he kept his distance, and asked again: "Did you go to the wrong place?"

"Yes," she looked down at him, and her body began to tremble slightly, so that she choked up when she spoke: "I went wrong, maybe I didn't go wrong."

"I'm Long Mu." The boy said patiently, "I'm also a staff member here. If you need any help, you can tell me."

But before he could comfort the woman, the other party suddenly began to cry.

It is always pitiful for a woman to shed tears, even if there is no crying sound, it will make people subconsciously want to comfort something.

But when the woman was crying, her expression was detached from her emotions.

She just looked down at Long Mu like that, without taking a deep breath, without pain, as long as her body was trembling instinctively, trembling so much that even the wide sash of her clothes was shaking slightly.

Big tears fell from her eye sockets as if uncontrollably, and before she even took any action, they began to scramble to flow out.

Long Mu had never seen such a crying method.

It seems that there is only something wrong with the eyes.

When people cry, shouldn't they have great mood swings?

In a short period of time, the woman's tears soaked a small piece of clothes along her cheeks, and she didn't intend to stop at all.

"I'm sorry," Long Mu slowed down, trying to make her feel better: "Maybe I can help you."

Yun Qi laughed, bowed his head and took out a handkerchief to wipe away the tears hanging from the corners of his eyes and cheeks.

Her movements are still not coherent, and one can feel that she is trying to control her body's reaction.

"Can I hug you?" he asked softly.

Yun Qi shook his head, stopped answering any questions, turned around and closed the door and left.

As if just a stranger going the wrong way.
