Correct use of scientific spells

When Xia Youjie received the news from the other party, his first emotion was confusion.

——He really didn't know the extent of the "secret of the world" that the other party said.

The existence of the Digimon world is a secret, and an ancient well connecting the Warring States Period and modern times is also a secret. As for the content of the research of those people, as long as it has nothing to do with magic spirits, it is not much different from science fiction to him.

Yuan Shan sent out a few photos of crows, talking freely.

— Hypothesis.

Assume that, before Miss Ming took the initiative to control with spells, the vast majority of crows did not have the ability to see the spell spirit.

Then it can be preliminarily inferred from this that she has completed some transformation of these crows, thus crossing the boundary line between "invisible" and "visible".

"So we dissected two different crows."

Yuan Shan said.

Biology is not his specialty, and certainly not Okabe and Hashida Zhi's specialty, so they entrust Hiyasada, who is barely an interdisciplinary talent, to help under the name of "a rare bird disease".As a result of the dissection, there was no difference in the eyeball structure of the two crows, and the staining range was highly consistent after local staining of the cone cells.

"Through this dissection, it can be judged that the eyes are not the key to being able to see the curse spirit—of course, the situation of Wujo-kun is temporarily excluded as a special case."

There are three elements in the formation of vision, which are the reception, transmission and processing of visual signals.If the receiving end is completely consistent, the next thing to consider is "delivery".

Cone cells in the eyes of birds are relatively abundant[1], and they are often used as research objects in vision, so quite mature existing data can also be collected-in this regard, chickens and The crow controlled by Miss Ming should not be much different.

After testing, there is no significant difference in the secretion of guanylate cyclase kinase and the chemical reaction of light conduction detected between the intervened crows and the native crows. What's more, these simple biochemical reactions cannot accurately determine the "field of view" Something in it" was taken out.

—then the only remaining optionality that has not been ruled out is obvious.

The brain is the most sophisticated organ in the living body, and it is also a piece of secret land that has not yet been discovered by human technology. It has a very complicated response mechanism in terms of visual signal processing.In addition, the brain itself has the function of "completely ignoring part of the visual information that can be seen". If you don't believe it, you can close one eye and do a little experiment: human beings can actually see their noses with the naked eye.

But most of the time, your brain tells you it doesn't matter.

To give the simplest example, according to the biological content of junior high school, the structure of the human eyeball follows the principle of convex lens imaging. The imaging of external optical information in the eyeball is actually an inverted image, but the brain will automatically process the visual signal to convert the image in the human eye The world is righted again.If the experimenter wears special glasses to make the visual information appear positive, then the world he sees within a period of time will be reversed instead.

However, if the special glasses are worn for a longer period of time, the brain will readjust the cognition, and the visual center will revert the scenery seen.This process is not transferred by human subjective will, but is completely automatic regulation of the nervous system.

Xia Youjie was a little dumbfounded when he heard this, but what Yuanshan Minato said next simply surpassed ordinary high school students' understanding of the world.

"So we considered swapping the brains of the two crows."

Xia Youjie:? ? ? ?

He leaned back and threw the phone out of his hand, almost hitting Gojo Satoru on the back of the head.

The mobile phone stayed very close to his head, and the white-haired conjurer who was playing the game was very upset, turned his head and held the "hidden weapon" that attacked him in his hand: "I just asked you to come play with me, don't you?" Yes, now come to bother me again!"

"No... just saw something that surprised me."

Xia Youjie stared at Gojo Wu's forehead with a dazed expression, "Now I feel a little scary about science."

Gojo Satoru:?

He frowned: "Do you have a stomachache? You always say strange things."

"……nothing."

Xia Youjie instinctively felt that this kind of thing was too far away from a simple magician like Wu, and it was not a topic suitable for happy communication with classmates: "I am talking about university with my senior."

"Oh."

Gojo Satoru lost interest and turned his head to continue playing games.They have visited Dongdian University several times, and they also know that this group of people is making magic tools for Miss Ming recently. It is nothing more than some progress, and he doesn't pay much attention to it.

"What about the results of the experiment?"

Xia Youjie asked cautiously.

"It hasn't been done yet. We don't have that kind of advanced surgical conditions here, and the funds are not very abundant. We have to consider a series of issues such as confidentiality."

Yuanshan Minou replied: "Anyway, I plan to wait until I receive the final payment from Miss Ming. Anyway, she said that the crow lease is also within the scope of entrustment. You can ask her for help at any time."

The earliest human animal head-changing experiments can be traced back to 1970. American brain science expert Dr. Robert White[2] used two rhesus monkeys to complete the head-changing operation. Unfortunately, because there was no way to bridge the nerves connected to the spine, the two All monkeys were paralyzed from the neck down.

However, this does not affect the processing of visual signals. Toyama Minato said that they only need to capture the tracking of the crow's eyes on the movement state of the magic spirit. The technology in this aspect is quite mature, which is equivalent to picking apples on the shoulders of giants.

Xia Youjie: "..."

It's totally doable.

From the proposal of the conjecture to the design of the experiment, in just a few months, this group of people completed the journey of exploration in the magic world that is often calculated in thousands of years.

By the time the research results were delivered, it was already winter.

Even though most of the technologies used have a theoretical basis, and the support team from the United States is luxurious enough, Miss Ming's commission still took them less than half a year.

The final result is a semicircular sensor that can be worn on the back of the crow's neck, which can transmit real-time visual signals to the receiving port through the base station, decode them locally, and convert them into dynamic images visible on the screen.Even with the most advanced communication equipment and processors, there is a delay of about five to ten seconds between the real-time picture and the picture observed by the crow. This is the inevitable processing time of signal decoding, and there is no way to continue to optimize it.

"This kind of thing can't be done without a supercomputer."

Hashida Zhi spread his hands together: "It can almost turn ten seconds into three seconds."

"But who would prepare a computing array the size of a house for such a thing?"

Minato Yuanshan then explained: "It is more cost-effective to sacrifice a few seconds of information processing time."

Pursuing cost-effectiveness is also one of the correct choices for businessmen, Mingming nodded, expressing that he can accept this little flaw.The handling, dismantling, and equipment joint debugging of the base station require them to provide technical guidance and training for a period of time. Except for the details of acceptance, they have already received 90% of the final payment.

For college students, this can be said to be rich in place.

"It can really be done!"

Hashida Zhi pinched his fingers and exclaimed: "At first I thought it was an impossible task!"

"Of course no problem! After all, this is the choice of Steins Gate—"

Okabe was talking nonsense again, but this time no one complained about him, and all the members of the laboratory were in high spirits.

Ruka Urushihara and Mayuri are also happy for them: after several months of feeding the crows, they are getting a little tired of the job.

On the computer screen, Xia Youjie's curse spirit is about the size of a flying football. It has sharp mouthparts like mosquitoes, can float without wings, and has a short, stinging needle like a scorpion. Tail.

"A breakthrough in biology."

Hong Liqi commented expressionlessly: "With this appearance, I still thought that I would never be able to fly no matter what."

"The image I made up at the beginning was a big fly."

Yuanshan Minato also said: "After all, when scanning with the sensor, it is always flying in the air, and the protruding beak can be seen in the computer."

"There is indeed a gap between the image scan and the real pattern."

Rintaro Okabe sums it up: "The image that was full of noise and sharpening aliasing before was really hard to make out."

Everyone couldn't help but look at the tempered glass. The inside of the glass was empty, and there was nothing in their field of vision.Before, they tried to blow a large amount of plastic foam dust into the space where the magic spirit was placed. Considering that the foam would collide and interfere with the magic spirit, they tried to see its position in a space full of opaque materials.But perhaps because the size of the target is too small, it can only barely recognize the orientation, and the effect is not as good as their scanner.

Probably because of Xia Youjie's order to the curse spirit, the curse spirit stayed where it was and didn't move, but it seemed a little sluggish after several months.Toyama Minato speculates that this is due to the lack of an effective energy supply - as long as a thing can move, it will definitely consume something, otherwise the first type of perpetual motion machine will be realized in this little monster invisible to the naked eye.

Obviously, the perpetual motion machine has not been realized, so it is not difficult to guess the energy source of the curse spirit: Toyama Minato recalled the curse spirit that once lay on Dr. Zhongba and was killed by Miss Ming with a crow.

According to the second law of mantra spirits, mantra spirits will always be malicious to human beings.So what is the reason why they can withstand this kind of malice and not kill the target immediately, the reason is very likely to be here.

Further guesses can be made: Dr. Nakabachi's jealousy towards Hong Liqi became the nourishment of the curse spirit, and the curse spirit may have affected his emotions to some extent. The two complement each other, just like a virus It reproduces and spreads in the human body and gradually expands the scope of influence.

By analogy, there should be many similar situations in society.Dr. Zhongba will never be an isolated case, otherwise, it would be impossible to form such a solid magician response system for thousands of years.

"It's really troublesome, a creature like a curse spirit."

Yuan Shanmin sat on the chair and stretched, feeling the clicking sound of the bones on his body, so as to relieve the fatigue of working at the desk for a long time.

"Not necessarily a living thing."

Hashida Zhi reminded him from a distance: "It is not a good habit to define too early."

Although prions are proteins, they are also viruses. Although whales live in the sea, they are also mammals. Strictly speaking, mantras are natural metabolites of humans. But who would think that the sweat they sweat after exercise will one day pose a risk of killing people?

The world is really wonderful, even if you think about it from afar, it is also full of dangers.

Fortunately, those young conjurers brought a strong sense of security.

Professor Reiskinen is busy with business and comes and goes like a breeze, and he also has a wide range of contacts in the Japanese academic circle. Except for the cute boy Luca, Japanese Shamangirls rarely appears in their group building occasions.The few remaining people immediately decided to have a small celebration, and everyone ate barbecue on the rooftop of the Lab—recently, they often hang out in the laboratory of Tokyo Electric Power University. The "Future Science Research Institute" that was pulled up by Okabe go seldom.

Fortunately, the rent has not been cut off, and the owner of the Tennoji Temple has been keeping these college students at a very low price. Now that they have returned to the base, everyone has decided to invite the owner and his daughter to have a big meal together.

"Why don't you call those high school students? After all, you helped me a lot before."

Hong Liqi suggested.

This is indeed a good idea, and Wutiao students will definitely be interested in this kind of activity. I heard that conjurers are busy with work in summer, and now it is almost the season of snowing. It just so happens that Lei Net released a new card group. Help me buy a set.

I would also like to thank student Xia You, if it wasn't for the safe enough magic spirit he provided, the progress of their experiment would probably be delayed for a long time.

After getting the first start-up capital, it was the mass production of the magic spirit detection machine, and then the salary was collected from the magic world as a "window", trying to balance the investment and income as much as possible, and trying to find a way to snowball. An industry-although there will be various problems in implementation, but he has a large group of reliable and smart friends, even if the road ahead is bumpy, he will definitely be able to go on.

This is the way to protect more human beings, which is different from the "other positions" of EVA drivers.

However, Toyama Minato called, but it took a long time to get a response.Xia Youjie's voice sounded a little tired, and he just paused after hearing his invitation, saying that he was not in Tokyo recently, and probably couldn't share the joy of their success together.

"I'm in Kyoto now."

"It might not be until next week," he said.

Kyoto is the base camp of the conjurer industry, and it is also the headquarters that has been passed down from Heian-kyo to the present. It is not surprising that Xia You classmates will occasionally go to Kyoto.Toyama Minato didn't think too much about it, but just welcomed him to come back and celebrate together. It just so happens that everyone has a lot of cash recently and can choose a famous restaurant with higher quality.

Xia Youjie hummed and hung up the phone.

He put the phone back into his trouser pocket, and stuffed it between the two curse spirit jades in his pocket.Kusakabe Atsuya stood next to him, with a gloomy expression and lowered his head: "Sorry, Xia You, I need to trouble you to help me with this kind of thing."

"Let's take it as a repayment for Mr. Kusakabe's advice to me some time ago."

Xia Youjie said, "As long as it's something I can help with, please feel welcome."

The gurgling water of Kamogawa has taken away countless lives for thousands of years.Kusakabe finally couldn't hold back, stretched out a hand to cover his eyes, and let out a breath slowly.

His sister's child, the nephew Xiao Wu who also has "talent", failed to survive this winter from the spell.
