Great Country Academician

Half an hour passed, and after browsing all the manuscript data, Xu Chuan finally raised his head and looked out the window into the distance, as if he wanted to see the country on the earth through the dark night.

"You really look down on people with the design of this step. Does this mean that none of us can solve the previous relationship?"

In front of the desk, Xu Chuan looked at the dark night sky and muttered to himself. After reading the information in his hand, he had already found the corresponding law of the functions used in the ciphertext.

Compared with the previous strict defense, in this last step, the opponent's design simply opened the door directly.

The rule design of the last step is actually very simple.

Anyone who has studied functions knows that most of the complex functions in this world, except for a very few, are composed of two or three or more functions.

This also means that a complex function can be split into several elementary functions as needed.

This is the simplest method used in these encrypted messages. They converted a function into a date and inserted it into the plaintext.

In this way, the final complex variable function can be determined only by determining the basic function and elementary function used according to the date.

And the date number of each day of each year will not be repeated, just like today is March 8, 2015, the number sewn into the plaintext after splitting is 20150308.

The specific position can also be determined. The first number is the second in the first line, and so on. If zero is encountered, the corresponding number of lines will be vacated.

This extremely simple incorporation can be discovered by anyone who is a little sensitive to mathematics.

The difficulty is similar to that of elementary school students playing to find the rules.

That's why Xu Chuan said to himself that the law design in the last step is really looking down on people, and he is sure that they can't solve the previous law, can't write the corresponding numerical model, so it doesn't matter whether they will be discovered or not.

After thoroughly uncovering the secrets behind the encrypted message, Xu Chuan sorted out the manuscripts. After familiarizing himself with various laws and data, he left the original ciphertext and plaintext manuscripts that needed to be returned. Other drafts and calculation data were It was burned and rushed into the sewer.

It is impossible and impossible for him to take these things away, but staying here is considered a disaster for him, and it may expose his secrets, so it is better to be cautious.

Not to mention the country, if the first district knows that this information war was solved by a high school student, he probably will not have any peaceful days in the future, and it is impossible for him to take a step abroad.

But it is impossible for him not to go abroad. A lot of theories and technologies in his mind are waiting to be reproduced by him with the help of the particle collider of the European Atomic Energy Laboratory.

In his first rebirth, he still chose Sanjiang College as his university, not only because of his feelings, but also because of the path he had traveled in Sanjiang College in his previous life and the reasons for his opportunities.

Just like he went to CERN with his mentor several times in his previous life, some opportunities only appeared in specific places.

After finding out the mathematical laws and secrets behind the encrypted message, Xu Chuan felt relaxed.

Although this matter has not been completely resolved, he believes that it will not take long for the corresponding mathematical model to be written.

He can't help much with the rest of the work.

He is not familiar with programming and cryptography, and does not need his help. There are quite a lot of talents in these two fields in China.

For him, the most important goal in high school has been completed, and he can prepare for IMO, IPHO and college entrance examination with peace of mind.

Although participating in such a competition as a reborn person feels like bullying a child, after all, no one has won the gold medals of these two competitions in the same year.

Xu Chuan still has some expectations for this new achievement.

Moreover, it was a pity that he failed to win the absolute winner on the IPHO in his previous life. He has the opportunity to make up for it in this life, so he naturally doesn't want to miss it.

The next day, in the early morning, Xu Chuan had already woken up when the sky was light.

Taking advantage of the Sun Moon University playground to run a few laps can be regarded as resuming the exercise that has been stopped in recent days.

In the morning, he didn't go to the information building, but took a stroll around the campus of Sun Moon University, and slipped into a classroom to listen to an open physics class.

College life and high school life are two completely different lives. In high school, teachers will watch you study and ask you questions and investigations.

But the university is an environment that actively acquires knowledge and accepts information, and presents it to the society that is bigger than the course itself. Except for the final exams, few teachers care about how well you are studying.

An open class like this is a good place for students to demonstrate their ideas.

Although it is a university course, Xu Chuan thinks this class is very interesting. The core of its theme is the 'thermal invisibility' effect, which is considered a cutting-edge topic in the physics world.

The concept of invisibility has long been a popular element in science fiction and science fiction movies.

After all, YY can tell a lot of harsh stories.

What interested Xu Chuan in this class was some ideas put forward by some young students in the class, or it should be said that they were seniors.

A senior proposed a new concept of "thermal cloak" in class.

In his idea, this kind of clothing is composed of countless small chips, each chip has its own processor, and can call the information of everyone's eyeballs, and can image, emit light, dissipate heat, cool, breathe, etc.

When a person wearing an invisibility cloak appears, each chip in the clothing will image the image originally seen by the observer at your position according to the visual information of the observer.

This kind of invisibility clothing can not only be visually invisible, but also has the ability of "thermal stealth", which can avoid the detection of thermal imagers.

The idea is very whimsical, and it is impossible to realize it with the current technology, but it provides Xu Chuan with another brand new idea.

In his previous life, he majored in physics and minored in materials. He also has a deep understanding of materials.

Although this kind of chip cloak is not very realistic, it is not impossible to achieve light and thermal invisibility.

In his previous life, he has studied many materials, and some nanomaterials can achieve quantum confinement effect through specific means, and use this effect to adjust the band gap of the material, and then produce some unique photoelectric effects.

To put it simply, there is a material that can project different images from different angles like a polygonal mirror, so as to integrate with the surrounding environment, thereby creating a blind angle that people cannot see through, making objects hidden inside invisible.

However, Xu Chuan didn't go deep into this line of thought. He paused after thinking about it briefly and recorded it in his brain.

The greatest value of invisibility should be in the military, but this is something he can't touch at present.
