The Science Fiction World of Xueba

"The mission of the rural teacher's plane is completed, and the evaluation is in progress... The evaluation is completed, and the completion of this mission is A. Congratulations to the host. It will greatly improve the teaching ability. In addition, the system will randomly select a piece of technology from this plane as a reward."

Pang Xuelin only felt a warm current rushing into his mind.

Suddenly there was something unclear in his brain. In the past, when he was in class, although he tried hard to explain all the knowledge points he wanted to explain, there were always some things that were not clear.

But now, Pang Xuelin has a feeling that even if an ordinary undergraduate student is in front of him, he still has a way to use a few lectures to make the other party understand his Ponzi geometry thoroughly.

Pang Xuelin opened his eyes, and saw the system's lottery turntable interface again.

Pang Xuelin was not in the mood to look at the rewards on the turntable, but asked:

"System, why did I leave the world of rural teachers so suddenly this time? I didn't even have time to say goodbye to Xiaohui and Ah Qing..."

"..."

"System, is it because some of the issues I discussed with the Consul of the Carbon-based Alliance are more sensitive, so you let me come back early."

"..."

There was still a silence.

"System, is the advanced civilization that made you stronger than Zero?"

"..."

"System, are you playing dead?"

"The system will not die!"

"MMP!"

Pang Xuelin cursed secretly.

The system is playing a rogue, and he can't help it.

"Okay, system, the last question. After I left the village teacher world, the time of the village teacher world has stagnated. I want to ask, is the time of the entire universe stagnant, or just a small area of ​​time?"

Pang Xuelin said.

This time, the system finally answered seriously: "After the host leaves the village teacher's world, all material time in the village teacher's world solar system will return to zero!"

"What's the meaning?"

Pang Xuelin was a little puzzled.

The system said: "Time returns to zero, that is, the entropy increase of all matter in the solar system stagnates, and the world outside the solar system will not be affected in any way. In the world of the village teacher, no civilization can observe the existence of the solar system again."

"Okay, you are awesome!"

Pang Xuelin couldn't help but heaved a sigh of relief.

No matter what, as long as I continue to grow, sooner or later in the future, I will be able to meet Xiaohui, Ah Qing and the others again.

After confirming that Wang Muhui and Su Anqing would have no problems, Pang Xuelin focused his attention on the lottery roulette in front of him.

The roulette wheel is divided into six areas, each representing six technologies.

The six technologies are:

1. The Singularity Bomb

Singularity bomb is essentially a particle, without size, and an atom is infinite compared with it. It is a miniature model of the singularity of the big universe, and has some parameters of the singularity of the big universe. Surrounding the singularity bomb is a miniature black hole with a diameter ranging from tens of meters to hundreds of meters. This kind of bomb is not man-made, but formed at the beginning of the creation of the universe. After the search fleets of the Carbon-Based Life Alliance and the Silicon-Based Life Alliance capture it, it can be detonated by special means. It is the only weapon in the village teacher world that can destroy stars.

2. Stellar leapfrog technology

Using stellar energy to open space-time wormholes for space-time jumps, the maximum jump distance is 200 light-years, which is an essential technology for superluminal space travel. The only disadvantage is that after the transition, it is easy to cause space-time distortion of the galaxy.

3. High-dimensional communication technology

Using high-dimensional space for super-light communication, even at both ends of the universe, communication can be guaranteed without any delay.

4. Holographic imaging technology

A technology that uses the principle of interference to record and reproduce a real three-dimensional image of an object. Ordinary photography can only record the intensity information (amplitude) of light, and the depth information (phase) is lost. In the interference process of holographic technology, the superposition of peaks and peaks will be higher, and the superposition of peaks and valleys will be flattened, so a series of irregular, alternating light and dark fringes will be produced, so that the phase information is converted into intensity information and recorded on the photosensitive material.

The first step is to use the principle of interference to record the light wave information of the object, which is the shooting process: the object to be photographed forms a diffuse object beam under laser irradiation; another part of the laser light is used as a reference beam to shoot on the holographic film, and superimposed with the object beam Interference is generated, and the phase and amplitude of each point on the object light wave are converted into a spatially varying intensity, so that all information of the object light wave is recorded by using the contrast and interval between the interference fringes. After the film with interference fringes is processed through developing, fixing and other processing procedures, it becomes a hologram, or a hologram.

The second step is to use the principle of diffraction to reproduce the light wave information of the object. This is the imaging process: the hologram is like a complex grating. There are two images, that is, the original image (also known as the initial image) and the conjugate image. The reproduced image has a strong three-dimensional effect and has a real visual effect. Each part of the hologram records the optical information of each point on the object, so in principle, each part of it can reproduce the entire image of the original object, and multiple different images can be recorded on the same film through multiple exposures. And they can be displayed separately without interfering with each other.

5. Quantum computer

Quantum computer is a kind of physical device that follows the laws of quantum mechanics to perform high-speed mathematical and logical operations, store and process quantum information.

The transformation it can realize for each superposition component is equivalent to a classical calculation. All these classical calculations are completed at the same time, and are superimposed according to a certain probability amplitude to give the output result of the quantum computer. This kind of calculation is called quantum parallel computing, and it is also the most important advantage of quantum computers.

6. Antimatter Technology

Antimatter is a particle of matter that is similar to a particle of matter but has the opposite electrical property. Every elementary particle has its corresponding antiparticle. When an elementary particle and its antiparticle meet, they are annihilated simultaneously, converted into energy.

...

Pang Xuelin's eyes lit up involuntarily.

This trip was not in vain.

Although the technological level of the earth in the world of "Village Teacher" is low, the technological level of this world has reached an extremely high level.

Therefore, the technical rewards given are also very embarrassing.

However, Pang Xuelin doesn't like the technologies of singularity bomb, stellar leapfrog, and high-dimensional communication.

Even if these technologies are drawn, it is like handing over the blueprints of nuclear bombs to primitive people, which is meaningless.

The earth in the real world simply does not have the possibility of realizing it in a short time.

The latter three technologies are a bit interesting.

Whether it is holographic images, quantum computers or antimatter, they all have certain application value.

Of course, even if antimatter is invented, it can only be used as a killer in the real world.

However, quantum computers and holographic images are more useful in the real world.

Among them, Pang Xuelin is most interested in quantum computer technology.

After all, whether it is a new home for MOSS or in future scientific computing, quantum computers have unique advantages.

"Host, do you want to start the lottery draw?"

"Start the lottery draw!"
