"This question is easy to understand, one-dimensional space is a point, two-dimensional space is a surface, three-dimensional space is three-dimensional, and four-dimensional space is curved. Therefore, the four-dimensional space can be understood as the universe, but it is not exactly the universe. So four-dimensional space is not absolute, but a relative concept. There are many people who think of four-dimensional space as three-dimensional space plus a timeline. In fact, it is a misunderstanding. In my understanding, the fourth dimension is not something like time and space. ”

"What's that?" Hu Xinrui looked at Zhang Ye a little strangely, feeling that this person seemed to be doing science popularization for herself. But something seemed interesting, so she couldn't help but ask.

"Thinking! I think it's thinking. Only thinking can lead to infinite possibilities. Therefore, the four-dimensional space should be the three-dimensional space plus thinking, not the so-called time or space. ”

"But what does this online game have to do with you?"

"It's understandable. You must know that similar to the holographic online game technology in the novel, it is a game similar to acting directly on the nerves of the brain. The nerve is the basis of thinking, so the game that directly acts on the cranial nerves can be regarded as a game that directly acts on the mind. ”

After a pause, Zhang Ye said again, "Therefore, at this time, the dimension has changed. The games we used to play were two-dimensional or three-dimensional games, and these games needed a medium to carry them. However, holographic games have changed in dimension, so there is almost no need for so-called media, and various generators and sensors are used directly to act directly on the cranial nerves. This is the shift in latitude. ”

"What if the latitude changes? Then why do you say that the time has been extended? ”

"For example, if I were to say the North Pole, what would you think of?"

"Ice and snow."

"And what about the moon?"

"Lunar landing plan, Chang'e to the moon."

"Yes, that's it. But when you think about that, the first thing that comes to mind is the endless ice fields, or the lunar surface of the craters, right? ”

"Yes!"

"And what about Pluto?"

"......" Hu Xinrui didn't say anything this time, but looked at him strangely like this, with an indescribable weirdness in her heart. Half an hour later. "What the hell do you want to say?" ”

"The Sun is so far away from Pluto that it takes almost two days for the light to get there. But you can think of it for a split second, and imagine the surface of a cold planet. ”

"What do you think of?"

"Thinking is fast, faster than the speed of light."

"That's right! Thinking fast. Beyond the speed of light, beyond time and space. Therefore, you can think of many things in a moment, and if your imagination is richer, you can even feel like you are there. ”

"Holographic games act directly on the cranial nerves, so to speak, directly on the mind. And thinking is limitless. Therefore, as long as the hardware equipment is good enough, it can allow people to come into contact with a lot of things in an instant in the fourth dimension. And it's directly on the nerves, so it's going to be hard to forget. What do you have in mind when I say this? Speaking of this, Zhang Ye's expression was quite like the madness and excitement of a scientific researcher.

Hu Xinrui is not a fool, she can pass the Jinshi in the Guangxu period by means, which shows that she is definitely not a stupid person. Coupled with the modernization theories she has been exposed to for so many years, she knows a lot of theoretical knowledge. When Zhang Ye said this, she quickly thought of a question. "Because of the shift in latitude, theoretically. The timeline has been extended. So theoretically, humanity will have an infinite amount of time. ”

"Yes! That's what it means. In my opinion, there are only two conditions that restrict the large-scale use of this technology, and if these two conditions are resolved, humanity will theoretically have an infinite amount of time. ”

"On what terms?"

"The capacity of the nerves, and the processing capacity of the hardware. Long-term high-speed operation of nerves consumes a lot of self, and at the same time, it will also cause pressure on nerves, and if you don't do well, it will burst blood vessels. The hardware capability is whether these bioelectric impulses can be fully captured. So that it can be parsed out, and then fed back. I think this amount of processing will be very large, and ordinary processors simply can't handle so much complex information. ”

"And you're still so excited?" When I heard Zhang Ye say this, Hu Xinrui was a little strange! Since there are these two constraints. So what is he excited about? Are these two problems solved?

"Because this kind of thing has basically been solved! Although I don't know the exact progress of the research, when I was talking to the housekeeper last night, he told me that the hardware development was basically completed. As for nerve pressure, there is no need to worry. It's just a small matter for me, and I don't have to worry about it at all. Now the only thing that is more troublesome is. How to build that game world. Because the data required is so great that even with the ability of a housekeeper, it will not be possible to get it for a while. ”

"Didn't you say that tomorrow would be fine?"

"Yes, tomorrow will be fine. It only takes until tomorrow, and I believe that these children will become doctors in a short period of time. And tap into your potential in the game. ”

"How did you come up with this?" Looking at Zhang Ye, Hu Xinrui felt a little strange.

This man doesn't seem to be the kind of super-smart master of the generation! How did you get along with each other in this way? It's too mysterious! If this technology is completed, then everything in this world will be turned upside down.

As long as you buy one of these instruments, as long as you can endure loneliness and spend decades on thinking, you can learn to become a university scholar throughout the ages. At that time, if people all over the world can endure loneliness, won't that mean that people all over the world can become university scholars in a short period of time?

Think about it, a moment ago, someone was still at the back of the crane, but after a night, he immediately became a postdoc. Learning methods will change dramatically, and learning time will be minimized. Even if you have been illiterate for 18 years, as long as you spend money to buy a device, or borrow a device from someone else, you can become a master of all kinds after one night.

Shaking!

The changes that this technology will bring to human beings will be earth-shattering. The consequences are more drastic than any steam engine or textile machine. Everything is going to be a game-changer.

Even if the fidelity can really reach more than 90%, then most of the rigorous scientific research work can be moved into the fourth dimension. In this way, the consumption of equipment, space and materials can be saved to the greatest extent.

"How? Do you think this technology is very high-minded? Zhang Ye leaned against the door frame and looked at Hu Xinrui with a smile.

"I don't see it at the top, but I think it's a subversive invention. Once this equipment is spread, the sensation and shock caused will surpass all inventions of the past. This kind of thing is good, but you have thought about it, sometimes good things do not necessarily get good results. ”

"I'm not unfamiliar with this question, so I'm not going to release the technology or start making equipment for sale right away. Instead, I plan to keep it at home and play it by myself. ”

"Why?"

"Not suitable! I have a housekeeper now, and I can put off everything else, and I'm not in a hurry. Although I am also human, I have to say that human beings have too much uncertainty. If this device were sold, God knows what would happen? When the time comes, after a little smarter people have mastered a lot of knowledge, won't they be able to make an atomic bomb in the kitchen? This kind of thing is too dangerous, so you have to be cautious. ”

"Also, almost everything can be found on the Internet these days. Just find a drawing, and you might be able to build a fighter in the living room. It's too dangerous! ”

"It's good to know. So my primary goal is not to sell things, but to give them to children. I believe that these little guys should be able to become very knowledgeable in no time after using these devices. ”

"But I don't think that's a good thing."

"Why?" Hu Xinrui's words were almost equivalent to a scoop of cold water, splashed on his head, making Zhang Ye feel a little cold.

"They're too small. Exposure to too much knowledge is not a good thing for them. It's like your fourth child. ”

"Uh......" Zhang Ye touched his nose, feeling that what Hu Xinrui said seemed to make some sense.

Ruier was born to know, she can run and jump when she is born, and she will make some messy things, and she always likes to pretend to be old. If these little guys are exposed to too much knowledge at this time, will they also become like Ruier?

Thinking that these little guys would gather together to discuss advanced knowledge such as m=pv, q=m/t, p=pRT when they were fine, Zhang Ye felt weird when he thought about it.

"It seems that this matter really needs to be thought through! Otherwise, it is not a good thing for children. Rubbing his head, Zhang Ye didn't know what to do.

The child is very intelligent and knowledgeable. This kind of thing is loved by every parent, but it would be cruel to deprive them of their childhood because of this. He's not going to let these little guys become old pedants. If that's the case, won't the children's coquettishness be gone?

All kinds of tricks and tricks are gone, and all kinds of crookedness are gone. Xiao Linglong won't shout for her father to hug her, and Xin'er won't lie on his head all day long. Thinking of this, Zhang Ye couldn't help but shudder, if this was the case, he would rather these children be stupid for the time being.

Looking at Zhang Ye, Hu Xinrui seemed to guess the concerns in his heart, and said, "Actually, I don't think you have to worry about anything about this kind of thing at all!" In fact, just go another way, and you'll be fine. There is no need to worry that these children will become old pedants who only know how to discuss all kinds of advanced knowledge. ”

"In what way?"

"Teach in a child's way! Don't you know that there is a word called edutainment? As long as you integrate all kinds of knowledge into the game, anything can be solved. At the same time, they still maintain the temperament of children, but they have a lot of knowledge in their heads. Isn't that great? ”

"Hmm...... Reasonable! Hu Xinrui's words almost made Zhang Yemao pause, "Just ask what you say!" I think that through play, these children should not become old pedants. (To be continued.) )
