Deep Space Fleet

Life is like this, as people wish, it has been so hard, it’s okay to live a simple and common life, who can guarantee that there will be enough foresight in a lifetime? At the crossroads of life, in addition to the postgraduate entrance examination, there are actually many choices, and not everyone is suitable for scientific research. Teachers, doctors, nurses, maintenance workers, etc., every occupation in the spacecraft must have.

The atmosphere at the dinner table gradually improved, and there were many things that I thought about when I wanted to.

The current society as a whole is still dominated by young people, classes have not yet solidified, and the entire social structure does not need to consider too much "money" issues, and the pressure is not that great.

"Using knowledge to achieve class transition is actually the healthiest way for human civilization to operate. Even if you don't get into a graduate school, you can still be like me. As long as you work hard, there are many ways to realize your own value." Finally, Big Brother Wang Xin Another life statement.

After having dinner with his friends, Zhang Yuan returned to his dormitory and began to learn new knowledge.

There is simply too much to learn about space mechanics.

A spacecraft, whether it is a large spacecraft or a small spacecraft, almost involves more than a dozen disciplines, large and small, such as physics, biology, materials, and chemistry.

He studies for a long time by himself every day.

Especially if you have to participate in a more difficult interview next time, even if it's just a temporary rush to study, it's not bad.

"...Let's start with the integrated circuit first."

Zhang Yuan opened "ASIC Design", a very classic book, mainly covering the basic process of digital integrated circuit and ASIC design, plus the main design methods, a total of 8 chapters.

When he was in college, he had received relevant knowledge, but it was not in-depth.

Actually...not too difficult.

The essence of silicon-based chips is actually very simple to understand: on the same semiconductor substrate, the PN junction has unidirectional conductivity, and the two ends of the PN junction are connected to wires to form a diode. With diodes, "AND gate circuits" and "NOT gate circuits" can be designed very simply, and then they can be used for logic calculations.

The Soviets once worked out a ternary circuit, which is slightly different from the binary circuit. There are two more resistors in the "AND circuit" and "NO circuit". But this difference is more troublesome for the manufacturing industry, the cost is high, and the yield rate of the chip is much lower. Because of various shortcomings, it is gradually eliminated.

It sounds like something so simple in principle has almost killed 99.9% of human beings in seconds!

Zhang Yuan felt that without the help of a computer, even if he spent a month designing a circuit, his calculation ability was no better than that of a six-year-old child...

To put it bluntly, the more you learn, the more you can understand the greatness of nature.

Chip science, a subject that has been developed for hundreds of years, from ancient diodes and integrated circuits to the latest photonic chips, its basic "energy band theory" is just an approximate theory. Humans clearly know that it is not completely correct, but There is no way to correct it.

Because the behavior of electrons is completely impossible to calculate accurately.

Going further, regardless of the complexity of various subjects, in fact, most of them are just playing with electronics.

As long as you are proficient in the various properties of electrons, the rest of the subjects can be understood by analogy.

After reading for six hours, he stopped and took a breath.

The fast-running brain is slightly hot, and it takes a certain amount of time to absorb these newly learned contents.

"It's better to change your mind and take a rest."

Went out for dinner, took half an hour.

He turned on the computer again, and found a lot of unprocessed messages in the mailbox, and opened and replied one by one.

The work project on earth is a good exercise opportunity, or to continue to do it. He is mainly engaged in the work on the algorithm framework, and the progress is a little faster than the team on the earth. Four or five hours a day is enough.

Therefore, studying for more than ten hours a day is definitely not a boast.

The above day is almost a very routine day for Zhang Yuan, and sometimes he feels very tired, but more of it is the sense of fulfillment brought by knowledge. Don't play games, don't watch soap operas, don't fall in love, and forcefully make yourself stronger.

Zhang Yuan sighed in his heart: "If Li Zhendong works so long every day, even if he is not better than me, he will still be half as good..."

But he deeply knows that what he is looking at now is just a little bit of superficiality. There are definitely many people stronger than him in the world.

The world's top academics are divided into 5 levels.

The first level is when on a long-distance trip, I hear a strange aunt bragging about how great her child is, and has been admitted to the city's key junior high school, high school, etc., ranking first in the class, second in the class, and so on.

This should be the lowest level of academic master.

It's just high school, I don't know what I'm bragging about...

The second level is that some people who also went to key universities also attended classes and self-study, and after a semester, they got a high score inexplicably.

After a long time, I will gradually realize that no matter how hard I try, I can't seem to surpass these people. They are always more efficient than ordinary people in the same study time.

Such talented people are usually called "true academic masters".

The third level, of course, is the legendary "God of Learning".

Unlike Xueba, Xueshen can get high marks without studying much.

They are the most dangerous people in the university. Many weak chickens without self-awareness follow them. They also play games online all night, but they fail several courses.

Suddenly looking back, that guy who was also playing around, also participated in some competitions and won some scholarships...

The weak chicken failed a grade and was repeated, but the "student god" went abroad.

The fourth level, which has already begun to march towards non-human beings, is called the real "god".

From the point of view of personal character, "God" is without any flaws.

They are both academic gods and academic masters. The most domineering part of this group of "gods" is naturally their physical strength and persistence. For them, learning is a very happy thing, just like chewing Xuan Mai, they can't stop at all.

Ordinary people will only pale in comparison to the "God", feel ashamed, and can't arouse any trace of jealousy.

Naturally, learning gods cannot be compared with real "gods". Because the ability to learn God is limited to the knowledge in textbooks, and the real "God" has long since jumped out of the scope of the school.

Zhang Yuan estimated confidently that he was marching in this direction...

There's even a fifth level, the "God of God" of course!

Witnessed only by the world's greatest geniuses.

For example, Academician Ding, the prospective tutor, is an undergraduate in the Department of Mathematics of University of P, majoring in mathematics, with 20 points of 100 points and 6 points of 99 points!

But he never brags about trivial things like full marks in exams. For these "Gods of God", exams, competitions, and scholarships are as childish as kindergarten games.

Ding Zhaodong was in the first year of university. In this year, he learned all the contents of the four years of university. By the way, he was a little bored, so he also learned the courses of the physics department next door...

However, these are not important. Only exploring the infinite nature is the joy in the life of "God above God".

There is someone stronger than Ding Zhaodong!

For example...Professor Wang Zhong!

Professor Wang became famous at a young age. At the age of 22, he produced a masterpiece that caused a sensation in the mathematics world - "Homologous Functions in Nuclear Space".

Zhang Yuan still has no way to understand this paper on algebraic geometry.

In the words of Professor Wang, the most talented brains in the world should study mathematics. For these engineering professors who have no emotional appeal and aesthetic ability, he doesn't even bother to talk to them...

Even if these people study day after day, year after year, and their accumulation has increased linearly over the past few decades, the gap between people is actually bigger than that between people and dogs.

So, what qualifications does he have to complain about it?
