Police Detective

"Is it possible that there is really some technology that can implant dreams in others?" Bai Song looked at Sun Jie.

If Professor Ye’s blog is true, generally speaking, there are two possibilities. One is that Professor Ye was frightened and automatically made up some things in his mind, resulting in a dream; the other is that someone influenced his dream. .

These two situations are unlikely. The first reason is that Professor Ye probably doesn’t know the tour guide. How could he know something he didn’t know in his dream? The second nature is because of this technology.

Therefore, the most likely violation of the above assumption is that the blog posted by Professor Ye is fake.

Then if Professor Ye’s blog is fake, it is unlikely to be a suicide.

"I think Professor Ye may have been hypnotized," Sun Jie said, "It is indeed a bit difficult to implant dreams. This requires implanting memories and the like from internal channels. If humans have this mature technology, they will be able to memorize words in the future. It’s too simple. But hypnosis is possible, and the hypnotized person’s subconscious can be influenced and controlled by others.”

"How much do you know about hypnosis?" Bai Song asked: "If this were the case, would there be anything different if Professor Ye dissected his brain after committing suicide?"

"This." Sun Jie shook his head: "Forensic doctors don't have this business."

"Okay." Bai Song didn't continue to embarrass Sun Jie. It's really hard to talk about hypnosis.

It stands to reason that people like Professor Ye are not easily hypnotized, but this is just "not easy" and does not mean "impossible". If Professor Ye was really frightened by that "adventure", it would be much easier to be hypnotized again. .

"The crux of the problem is actually not this." Wang Huadong frowned at the side.

As an on-site investigator, the scene where the tour guide died just now was too simple for him. He could really see the clues in it just by looking at it three times, five times, five and two times. However, no matter how you look at this scene, it is a suicide.

To put it bluntly, if this was not the death of Professor Ye, but another daily case, he could have concluded that this person committed suicide.

"My opinion is still suicide," Wang Huadong said: "This is the consensus, but our focus should not be here. You must know what happened to the little girl. This is the most critical thing. "

"Huadong is right," Sun Jie said, "Are there no progress made by the professors we found?"

"They are all professors of mechanics and the like," Bai Song said, "I feel that the field is not quite right. I mentioned this matter to Mr. Ren a few hours ago. An optics professor is on his way over. He will be here soon. I feel that there will be a new one." breakthrough."

"Optics?" Wang Huadong seemed to understand Bai Song's analysis: "Yes, I understand."

After one hour.

There are specialties in the art industry, but this thing is unacceptable.

Physics becomes more specialized the deeper you study it. Except for a few professors who cover a wide range of topics, most of them only study one field. The person who came this time was an optics professor from Nanjiang University. His surname was Xu, and he was well-known in the field.

Ren Hao already attached great importance to some of Bai Song's words, and the person invited this time was indeed a big shot.

"Let me read the transcript first," Professor Xu made this request after reading the video and photos.

"Read the transcript?" This was the first time Bai Song heard that the professor also wanted to read the transcript.

"Well, the two waves of people who have seen this girl only have descriptions and no video data." Professor Xu said: "It depends on your writing skills."

Bai Song and others brought the transcript, and Professor Xu considered it carefully for a while, then looked at the video and photos.

"I have an idea, you can listen to it," Professor Xu said.

"You tell me!" Bai Song sat more dignified.

"Pepper's Illusion," the professor said, "According to the current scientific level, this is the only way to fake it."

"What is this?" Bai Song was the first to ask.

"Actually, it's very common, it's fake holographic projection technology," the professor said, "This thing is often used in stage magic."

"Can you tell me the principle?" Bai Song said: "How can you deceive Professor Ye so close?"

"It's impossible. You can't deceive Professor Ye. It's too close." The professor said, "I don't have this technology. But I can tell you about this Pepper illusion."

Speaking of which, this is not a difficult technique and is used on many stages.

"Pepper's illusion uses a kind of transparent film made of glass or other materials. The refractive index of this film is completely different from that of air, and the refractive index of light in it is also different, so there is a chance of forming a phase, do you understand?" The professor said.

"?" Bai Song said, "Can you explain it in detail?"

"Due to different refractive indexes, when light reaches the interface of materials, part of it will be reflected and part of it will be transmitted. This amount of light can be controlled by the Fresnel equation. Simply put, when talking about reflection and refraction, the electric vector and the incident "The relationship between electric vectors, the specific expression." The professor began to talk non-stop for more than ten minutes: "Do you understand?"

Bai Song applauded directly, and several other people also applauded when they saw Bai Song like this.

"Um, do you understand?" Professor Xu asked.

Bai Song was a little embarrassed: "Professor, can you give us a demonstration of this?"

"Well, I have courseware here, you can take a look."

Then, Bai Song saw an experimental setup.

One image, two rooms (one of which is out of sight of the viewer), with a glass wall between the viewer and the two rooms.

The light emitted from the image will be refracted when it enters and leaves the glass. The audience can see the image on the glass, but cannot see the glass at all. The glass seems to be in mid-air, so the image appears in mid-air like a ghost.

After watching the demonstration video, Bai Song felt that it was still very shocking. This is the power of science. After thinking about it, Bai Song said: "In that case, this can be consistent with the transcripts of the two groups other than Professor Ye, and can even be consistent with the video and Professor Ye was so close to the content in the photo, so how could he not see it clearly?"

"This does not belong to the field of our optical research." Professor Xu looked at Bai Song: "Officer, I feel that you may have a misunderstanding. That is, how should I put it? Let me ask you, are there any people in your police force? Are they all good people?”

After listening to Professor Xu's words, Bai Song suddenly understood!

Problem solved, this Professor Ye acted from beginning to end and was lying! Professor Ye is not a good person at all!

This can solve many problems, but it cannot explain why Professor Ye died. Of course, this is not what Professor Xu is responsible for. This big boss has completed his work perfectly.
