Life is like this, as people wish, it has been so hard, it is not impossible to live a simple and popular life, who can guarantee that there will be enough foresight for 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 doing scientific research. Teachers, doctors, nurses, maintenance workers, etc., every profession in the ship must be there.

The atmosphere at the dinner table is gradually improving, and many things are thought of when I think about it.

At present, the whole society is still dominated by young people, the class has not yet been solidified, and the entire social structure does not need to consider too many "money" issues, and the pressure is not so great.

"The use of knowledge to achieve class leaps is actually the healthiest way for human civilization to operate. Even if you don't get into graduate school, you can be like me, as long as you work hard, there are many ways to realize your value. In the end, Big Brother Wang Xin made another life speech.

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

There's so much to learn about space mechanics.

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

He would study on his own for a long time every day.

Especially if you have to participate in a more difficult interview in the future, even if it is just a temporary surprise study, it is also good.

“…… Let's start with integrated circuits. ”

Zhang Yuan opened "Application Specific Integrated Circuit Design", a very classic book, mainly covering the basic process of digital integrated circuit and application-specific integrated circuit 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.

In fact...... It's 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 the wires, which is the diode. With diodes, it is easy to design "AND gates" and "NOT gates", which can then be used for logic calculations.

The Soviets once came up with a ternary circuit, which was slightly different from the binary circuit, with two more resistors in the "AND gate" and "NOT gate". But this difference is more troublesome for the manufacturing industry, the cost is large, and the yield of chips is much lower, because of various shortcomings, so it is gradually eliminated.

Something that sounds so simple kills almost 99.9% of humanity in seconds!

Zhang Yuan felt that without the help of a computer, even if it took him a month, the computing power of designing circuits would not be comparable to 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 discipline that has been developed for hundreds of years, from ancient diodes, integrated circuits, to the latest photonic chips, its basic "band theory" is only an approximate theory, and human beings know that it is not completely correct, but there is no way to correct it.

Because there is no way to calculate the behavior of electrons precisely.

To put it further, don't look at the complexity of various disciplines, in fact, the vast majority of them are just playing with electronics.

As long as you are proficient in the various properties of electronics, the rest of the disciplines will be able to touch on the others.

After reading the book for six hours in a row, he stopped and took a breath.

The fast-moving brain is slightly hot, and it takes time to absorb the newly learned content.

"Let's change our minds and take a break."

Went out for dinner and spent half an hour of your time.

He turned on the computer again and found a large number of unprocessed messages in the mailbox, which he clicked on and replied to one by one.

The work project on Earth is a great opportunity to exercise, and it is important to keep doing it. He's mostly working on algorithmic frameworks, and he's moving a little faster than the teams on Earth, and four or five hours a day is enough.

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

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

Zhang Yuan sighed in his heart: "If Li Zhendong works so long every day, even if he is not better than me, he will have more than half of the level......

But he knows deeply that what he is currently seeing is only a little scratch of the surface. There are definitely many stronger people in the world than him.

The world's top students are divided into 5 levels in total.

The first level is when I heard a strange aunt brag about how good her child was during a long-distance trip, and she was admitted to the city's key junior high school, high school, etc., first in the class, second in the class, and so on.

This should be the lowest level of top students.

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

The second level is that after going to a key university, some people also attend classes and study on their own, and after a semester, they inexplicably get a high score.

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

Such cattle are often called "real scholars".

The third level, of course, is the legendary "god of learning".

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

They are the most dangerous people in the university, and many weak chickens who have no self-knowledge follow them, and they also play games online all night, but they hang up several classes in the mix.

Looking back suddenly, the guy who was also playing around had participated in some competitions and won some scholarships......

The weak chicken failed to repeat the grade, but the "study god" went abroad.

The fourth level, which has begun to march towards non-humans, is called the true "god".

From the point of view of personal morality, "God" is without any blemish.

They are both gods and scholars, and the most domineering place of this group of "gods" is naturally physical strength and continuity. Learning is a very happy thing for them, and they can't stop just like chewing Xuanmai.

In the face of "God", ordinary people will only be dwarfed, feel ashamed, and cannot raise any trace of jealousy.

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

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

There is even a fifth rank, of course, the "god of gods"!

Only the greatest geniuses in the world can bear witness to it.

For example, the intended tutor, Academician Ding, is a bachelor's degree in the Department of Mathematics of P University, a mathematics major course, with 20 100 points and 6 99 points!

But he never brags about the trivial matter of getting a perfect score in the exam, and for these "gods of God", exams, competitions, and scholarships are as naïve as kindergarten games.

Ding Zhaodong was in his first year of college, and in this year, he learned all the content of the four years of college, and by the way, he was a little bored, and he also learned the courses in the physics department next door......

However, none of this matters, only the exploration of infinite nature is the joy of the life of the "God of God".

Someone stronger than Ding Zhaodong, there is!

For example...... Professor Wang Zhong!

Professor Wang became famous at a young age, and at the age of 22, he had a sensational work in the mathematical world - "Cohomology Functions in Nuclear Space".

Zhang Yuan has not been able to understand this paper on algebraic geometry until now.

In Professor Wang's words, the world's most talented minds should study mathematics. He didn't bother to talk to these engineering professors who had no mood or aesthetic ability......

Even these people study day after day, year after year, and the accumulation over the decades increases linearly, and the gap between people is actually bigger than that between people and dogs.

In this case, what right does he have to complain?
