Life is like this, as people wish, it is already hard to do so. It is not impossible to live a simple and simple life. Who can guarantee that you have enough vision and insight in your life? At the intersection 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., and every profession in the spacecraft must be available.

The atmosphere on the dining table gradually improved, and many things were just like that.

The entire 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 that great.

"Using knowledge to achieve class leap is actually the healthiest way of human civilization. Even if you don't get into graduate school, you can still be like me. As long as you work hard, there are many ways to realize your value." Finally, Brother Wang Xin made another life comment.

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

There are so many things to learn about space mechanics.

A spacecraft, whether it is a large or a small spacecraft, involves more than a dozen disciplines, including physics, biology, materials, chemistry, etc.

He teaches himself for a long time every day.

Especially in the next step, we have to participate in a more difficult interview, which is good even if we just cram the opportunity to study.

“… Let’s start with integrated circuits first.”

Zhang Yuan opened "Purpose-Special Integrated Circuit Design", a very classic book, mainly covering the basic process of digital integrated circuits and application-Special Integrated Circuit Design, plus the main design methods, a total of 8 chapters.

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

Actually...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 connecting the two ends of the pn junction to a diode is a diode. With diodes, "ANG gate circuit" and "Non-gate circuit" can be designed very simply, and then it can be used for logic calculations.

The Soviets once developed ternary circuits, which were slightly different from binary circuits. There were two more resistors in the "AND gate circuit" and "Non-gate circuits". However, this difference is more troublesome for the manufacturing industry, with high costs and much lower yields of chips. Due to various shortcomings, they were gradually eliminated.

It sounds like something that is so simple, almost kills 99.9% of humans in seconds!

Zhang Yuan felt that without using computers, even if he spent a month, his computing power in designing circuits was not as good as a six-year-old child...

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

Chip science is a discipline that has been developed for hundreds of years, from ancient diodes, integrated circuits, to the latest photonic chips, its basic "energy band theory" is actually just an approximate theory. Humans clearly know that it is not completely correct, but they cannot correct it.

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

To put it further, although the various disciplines are complicated, most of them are just playing with electronics.

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

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

The rapidly moving brain is slightly hot and it takes a certain amount of time to absorb these new learning content.

"Let's change your mind and take a break."

I went out for supper and took half an hour.

He opened the computer again and found a lot of unprocessed information in his email. He clicked it one by one and replied.

Work projects on Earth are a good exercise opportunity, and we still have to continue to do it. He mainly engages in work on algorithmic frameworks, and the progress is faster than that on Earth teams. It is enough to spend four or five hours a day.

Therefore, more than ten hours of study every day are definitely not bragging.

The above day was almost a very regular day for Zhang Yuan. Sometimes he felt very tired, but it was more of a sense of fulfillment brought by knowledge. He did not play games, watched soap operas, and fell in love, so he made himself stronger.

Zhang Yuan sighed in his heart: "If Li Zhendong worked for so long every day, even if he was not as good as me, he would be more than half of his level..."

But he knew deeply that what he was looking at was just a little bit of fur. There were definitely many people in the world who were better than him.

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

The first level is that during a long trip, I heard a strange aunt brag about how amazing her child was, and I was admitted to the city's key junior high school, high school, etc., first in the class, second in the class, etc.

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 after entering a key university, some people also attended classes and studied by themselves. After one semester, they inexplicably got a high score.

As time goes by, I gradually find that no matter how hard I try, I seem to be unable to surpass these people. With the same study time, they are always more efficient than ordinary people.

Such great people are often called "real academic masters".

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

Unlike academic masters, if the academic god doesn’t study much, he can get high scores.

They are the most dangerous people in college. Many weak chickens who are not self-aware follow them and also play games online all night, but they have been to several courses.

Looking back, the same guy who was playing tricks also participated in some competitions and scholarships...

The weak chicken failed the class and was reincarnated, but the "god of learning" went abroad.

The fourth level has begun to march towards non-human beings and is called the true "god".

From the perspective of personal morality, "God" has no flaws.

They are both academic gods and academic masters. The most domineering part of these "gods" is naturally physical strength and sustainability. Learning is a very happy thing for them, just like chewing Xuanmai, you can't stop at all.

When ordinary people face "God", they will only dwarf the comparison, feel ashamed and cannot raise any trace of jealousy.

Naturally, the God of Learning cannot be compared with the true "God". Because the God of Learning is limited to the knowledge in the textbook, the real "God" has long since broken out of the scope of the school.

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

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

Only witness can be witnessed in the greatest genius in the world.

For example, Academician Ding, the intent tutor, is from the Mathematics Department of P University, a major in mathematics, with 20 100 points and 6 99 points!

But he never boasted about the trivial matter of getting full marks in exams. For these "gods of gods", exams, competitions, and scholarships are as naive as kindergarten games.

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

However, none of these matters. Only exploring infinite nature is the joy of life in the "God of God".

There are people who are stronger than Ding Zhaodong!

For example...Professor Wang Zhong!

Professor Wang became famous at a young age and at the age of 22, he created a masterpiece that caused the mathematics community - "The Homotone Function in Nuclear Space".

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

In Professor Wang's words, the most genius in the world should study mathematics. For these engineering professors who have no mood and aesthetic abilities, he simply disdains to talk to them...

Even these people learn day after day, year after year, and the accumulation over the past few decades increases in a straight line, the gap between people is actually larger than that between people and dogs.

In this way, what qualifications does he have to complain?
