After the breakup, a song without makeup resonated with the entire Internet

"First of all, let's warmly welcome Jiang Yu to my show." Zhu Yongquan said with a smile: "Teacher Jiang Yu can be said to be a frequent guest on our TV station. He often guest on the show of the person next door, and the ratings are simply , which makes our other colleagues very envious. I finally invite you to my program today. Thank you again for coming to my program."

"No way." Jiang Yu smiled lightly: "I should be grateful to you for providing me with such an opportunity."

Zhu Yongquan smiled: "Okay, let's get started. Qian Laoyou just talked about your latest work "The Three-Body Problem", so we can talk about the circumstances under which you made this novel that shocked the whole world. What was produced?"

Jiang Yu smiled.

"Actually, at the beginning of this year, I went to other countries to promote my movies, but I met several teachers, one of whom was a big figure in the science fiction world. When we were chatting, he said that there is no science fiction in our country. works, so we made an appointment to compete. I must make a qualified science fiction movie to compete with him, so I appeared."

"Oh, so you're going to make "The Three-Body Problem" into a movie?"

"That's not true." Jiang Yu smiled: "There are some very detailed issues in the work "The Three-Body Problem". It is difficult to accommodate them all in a mere 120 minutes. I prefer to film this work as The TV series that I really want to compete with him is currently being filmed, and it is also a very good movie that I think will be on the shelves next year."

After all, I'm here to be on a show, so it's not too much to advertise my movie.

Of course, everyone is not very disgusted with this kind of thing.

"Then we are looking forward to this work." Zhu Yongquan smiled, and then looked at Mr. Yang: "Actually, I also read the novel "The Three-Body Problem". Let's put the other issues aside first. I am interested in "The Three-Body Problem". One of the reasons why the Three Body people want to stop Wang Miao from producing nanomaterials is to build a space elevator and deploy a defense outside the earth. Mr. Yang, do you think this space elevator is possible?"

"I am a person engaged in science and technology. I am very interested in the contents of the book, which are those ideas about science, such as proton engineering, and the multi-dimensional plane in which protons unfold, including space. There’s an elevator.”

Mr. Yang smiled.

"In fact, we have also specifically discussed the concept of a space elevator. Theoretically speaking, there is no suspense about the realization of this space elevator."

"But the biggest difficulty in stopping this idea now is the same as what Jiang Yu wrote in the book. It is the problem of materials. To solve this problem, we must choose a material with very high strength, low density and extremely strong tensile strength. Tall and strong enough, it's difficult to achieve with this material."

Hear what Mr. Yang said.

The audience in the live broadcast room immediately started discussing.

[It’s really difficult to realize. Materials with this strength would have to be found on planets with a density higher than neutron stars, right? 】

[No way, the neutron star is so dense and the mass is too high. 】

【What's the meaning? Come on, brother, please explain to me, what does neutron star density mean? 】

[I’ll explain it to you in detail. Let me give you a few examples. It’s the spoon you usually use to drink soup. The mass of a neutron star is as heavy as Mount Everest, or a neutron star the size of a basketball is as heavy as our earth. Heavy. 】

[Hey dear, if the density is so high, then the intensity must be enough. Shouldn’t that be possible? 】

[Brother, quality, our strongest material now is carbon fiber. It has low density and high strength. But even with such a material, the distance we can lift it into the air is only 200 kilometers. If the density is too high, the quality will be reduced. It is too big. For the elevator's steel cable, the pressure area is small, and the ground may be pierced by then, which is very difficult. 】

[So that’s it, darling, I finally understand. I’m sorry, I’m not very good at studying. I really don’t deserve to read this novel. 】

Zhu Yongquan nodded: "So, at present, it is still difficult to realize it in terms of materials?"

"Actually, we have a lot of theoretical knowledge." Mr. Qian said: "But the materials I have discovered at this stage have prevented the realization of countless theories, so we still need continuous progress and development, so that we can put many What exists only in theory develops into reality.”

Zhu Yongquan smiled: "Speaking of this scientific development, there is a core content in "Three-Body", that is, our science stopped and was blocked by the enemy. It would be like the end of the world. Mr. Qian, what do you think? I don’t know if you have any impression of this plot, but what will happen if our human science really stagnates?”

Mr. Qian raised his eyebrows: "I haven't thought about this yet, because our duty is to continuously advance technology. I think it's better to let Jiang Yu express his thoughts."

Zhu Yongquan looked at Jiang Yu: "Jiang Yu, can you tell me your views on the cessation of science?"

Jiang Yu thought for a moment and nodded: "In fact, in my opinion, perhaps the slowdown in scientific development is the greatest danger to mankind."

Zhu Yongquan's eyes lit up: "Can you elaborate more in detail? Perhaps in everyone's perception, war, disease, or environmental pollution are the greatest dangers to mankind. Why is it said that the slowdown in scientific development is the greatest danger to mankind? ?”

Jiang Yu said: "Actually, diseases, infectious diseases, and wars, throughout history, such things have happened in basically every period of time. Plagues that could not be solved in ancient times, such as smallpox, and wars, have all It keeps appearing, and even now, it has not stopped.”

"But smallpox has been solved by us. I believe that diseases, even terminal diseases such as cancer, will be solved by science one day. As for war, I admit that it is indeed the biggest danger to mankind. But in the final analysis, this danger lies in mankind itself. , the competition for the environment and resources.”

"In my book, I believe you have also seen something. Resources and the environment are conserved. There are only so many resources on our planet. Human beings are greedy, which is why wars occur. It is all for the sake of Competing for resources.”

"Actually, the biggest crisis is created by us humans."

“But what prevents this, isn’t evolving science?”

"For example, what we have always advocated is sustainable development, garbage classification, and using garbage that can be recycled to create new value. These are all things that can only be created because of the development of science, aren't they?"

"So I think the biggest crisis in our future is not the things we see now, but the slowdown in scientific development. Once scientific development becomes slow and human greed or desires cannot be satisfied, then it will be even greater. Crisis, right?”

"As written in the book, the development of science means the destruction of the environment. This is indeed a cost of developing science, but it is science that can manage this cost. After all, do human beings also need to survive? Moreover, in the universe, we I don’t think that our situation as human beings is unique. In such a big universe, why are we the special ones?”

"Therefore, to ensure that alien civilizations like the Trisolarans are not allowed to appear, we will not take the initiative to invade others, but we must also have sufficient ability to protect ourselves. This is also a necessity for scientific development."

"Of course, I think science and technology cannot go astray. It must develop on the right track. Only then will it gradually get better."
