Rebirth of science and technology academic master

Chapter 80 Calculus

Jingtian's agent was filled with emotion and joy at the same time.

The original signing of Jingtian was based on the belief that Jingtian had good appearance, sweet appearance, and was born to eat this bowl of rice. He belongs to what Zhang Laomouzi said, God rewards rice to eat. And although my understanding is a bit poor, the key is to work hard.

Coupled with some connections in Jingtian's family, there is no shortage of resources, and he is not afraid of not becoming popular.

But the manager never expected that Jingtian would become famous so quickly, and even become so popular that he almost turned purple. If it weren't for Jingtian's image and future development, there would be no problem at all doubling the endorsement contract.

There are also commercial performances, and the appearance fee has also doubled. If a commercial performance does not have 100,000 or 200,000 yuan, it is impossible to invite Jingtian.

This time, a large shopping mall in Magic City spent 200,000 yuan to hire Jingtian Commercial to perform in order to gain popularity at the end of the year. He only needed to sing three songs and boost the atmosphere, and he could earn 200,000 yuan in less than an hour. This is better than anything else. Money comes quickly!

What a money tree!

I have to set up a longevity card for Professor Qin when I get back! the agent muttered to himself.

The commission she received from Jingtian was more than ten times more than the sum of the artists under her.

The agent is most grateful to Qin Yuanqing now. In her heart, Qin Yuanqing is the God of Wealth, the kind who turns stone into gold. Such a person must be well supported.

Qin Yuanqing, who is regarded as the God of Wealth, naturally doesn't know that he has a God of Wealth hat on his head, and even if he knows, he doesn't care.

At this time, he was immersed in the ocean of books and the vast sea of ​​mathematical knowledge, constantly absorbing relevant mathematical knowledge.

As for the Hailstorm Conjecture, he still had no clue, so he just read random math books and earned some study coins.

Ever since he spent most of his learning coins in exchange for car engine technology, his learning coins now only have 200. Alone, Qin Yuan cleared the air at the beginning of his rebirth and had never been so poor.

Since the system was upgraded to an intermediate system, there is no longer a task bar, so Qin Yuanqing will be rewarded for solving difficult problems.

What Qin Yuanqing didn't know was that he had already shocked the people around him by reading a book in half an hour.

So this is a top student. It takes me a month to read a book, but others don't need half an hour. It's still math! A female classmate actually felt a touch of sadness in her heart.

Mathematics, for most girls, is like a sacred book. After studying it for a year and a half, you may not be able to understand anything.

No wonder someone has already proved two world-class mathematical problems in just half a semester and won the first prize of the National Natural Science Award! A junior girl was very emotional. God rewards hard work, and it is indeed not unreasonable!

I heard that Professor Qin's IQ is as high as 200, but I don't know if it's true or not! The two little girls murmured in a low voice. During the exam week, everyone went to the library to cram in and have a good impact to avoid failing the exam.

Now I accidentally saw Qin Yuanqing's speed of flipping through the book, and suddenly he couldn't read the book anymore.

What an outstanding man, compared to others, his boyfriend is simply outclassed! Woohoo, why was I so stupid back then, and was blinded by sweet words? No wonder the senior sister said fire prevention, theft prevention, and senior classmate prevention, but it was a pity that it was too late for me to understand this truth!

However, this girl has made up her mind to learn about her experiences and feelings on the forum and wake up the school girls. She must be on guard against the seniors, otherwise she will definitely regret it!

If you were outstanding, how could you become a senior single? ?

It would be great if I could have a boyfriend who is a top student! A girl's eyes were full of peach blossoms, but she didn't notice at all that her boyfriend beside her was already furious because she had a certain cuckold on her head.

If it weren't for the library, I would have given this woman a good beating.

This calculus is indeed one of the most important mathematical tools in the history of mathematics development! Qin Yuanqing was very moved after reading a book explaining advanced calculus.

Calculus is a branch of mathematics in higher mathematics that studies the differential, integral and related concepts and applications of functions. It is a major branch in the field of mathematics and can be said to be a basic subject of mathematics. The entire calculus includes limits, differential calculus, integral calculus and their applications. Its existence enables functions, speeds, accelerations, and slopes of curves to be discussed with a common set of symbols. It provides a common method for defining and calculating area, volume, etc.

Everyone's impression of Newton is that he was the greatest physicist who established the system of classical mechanics. But in the same way, Newton was also a great mathematician. In his 1671 book The Method of Streams and Infinite Series, he pointed out that variables are generated by the continuous motion of points, lines, and surfaces, denying his previous The variables considered are stationary geometries of infinitesimal elements. He called continuous variables flow quantities, and the derivatives of these flow quantities called flow numbers. The central problem raised by Newton in fluxes is: given the path of continuous motion, find the speed at a given moment (differential method); given the speed of motion, find the distance traveled in a given time (integral method)!

It can be said that it was Newton and Leibniz who created the mathematical branch of calculus, which has made calculus still exude strong vitality after hundreds of years.

From the Middle Ages to the present, it has to be said that the development of the West has indeed surpassed the development of the East. In the field of natural sciences, mathematics, physics, chemistry, biology, etc. are all ahead of the East. The contribution made by the West in the field of natural sciences Far larger than the East, that is why the West has dominated the world for five hundred years, and the world hegemons for these hundreds of years were all born in the West.

Nowadays, all Chinese people are learners, learning Western knowledge and wisdom to develop themselves.

The more he understood mathematics, the more Qin Yuanqing felt that mathematics is too much about talent. Without enough talent, you will not be able to achieve any great achievements no matter how hard you work. Genius mathematicians can often achieve great results with a flash of inspiration.

Among the great mathematicians such as Newton, Gauss, Descartes, Euler, etc., which one is not gifted, and which one is not extremely intelligent?

Are there any ordinary people who study hard and make achievements in the field of mathematics?

No!

not a single one!

Realizing this, Qin Yuanqing felt that it was not advisable to popularize education on a large scale like the one in Huaxia, where mathematics was included in the knowledge system of primary school, junior high school, and high school, and accounted for a large proportion. Because most of the mathematical knowledge is not used in a person's life.

For example, calculus. Who among ordinary people in society uses calculus?

For example, the Pythagorean theorem and other theorems, can ordinary people use them in life?

Including English, unless they are working as a translator or going abroad, most people will not be able to use it after they join the workforce after graduation. This consumes the efforts and youth of countless Chinese people. I don’t know how many people learn English because of it. Because of the difference, he embarked on a different path in life.

Qin Yuanqing secretly shook his head. China's education should indeed be reformed and continue to keep pace with the times.

Unknowingly, the library management staff began to remind students that there were only 15 minutes left before closing, and students were asked to leave the library in time.

Qin Yuanqing put down the book and put away the draft paper on which he had written something.

Shuimu Campus looks very quiet at night. It snowed heavily in the sky, covering the ground with a thick layer of snow. The northwest wind blew, and the coldness was quite unbearable.

Under the street lamp, there is a silvery outfit!

Qin Yuanqing tightened his clothes. It was unbearably cold in this winter. It was raining heavily and the northwest wind was blowing. It was almost life-threatening.

In comparison, southern Fujian is better. It's still over ten degrees Celsius at this time, and you can still get some sunshine at noon. It's nowhere like Beijing, where it's over minus ten degrees Celsius, with heavy snow and northwest wind.

When they returned to the dormitory, the three little fat guys were already hiding under the covers, all shivering, while the wind was howling outside.

The boss is back, I wish he wasn't buried in the snow! When the little fat man saw Qin Yuanqing coming back, he greeted him with a smile, just like a traitor.

Hey, why does it smell like perfume? Qin Yuanqing sniffed it with his nose and said in surprise: Your little girlfriend came to the dormitory at night!

Qin Yuanqing put the draft paper into his schoolbag. His manuscripts were very precious. He will also donate the manuscripts of Zhou's conjecture and the twin prime conjecture to the school in the future for collection in the school museum.

Hey, what's the sound? Qin Yuanqing's ears twitched and he looked towards the little fat man's bed with a puzzled expression: Little fat man, why do you feel that you have gained a lot of weight?

No, no, no, boss, you are wrong! The little fat man shook his head repeatedly and denied.

But Qin Yuanqing's eyes were already wide open, because he saw a little girl emerging from the quilt on the inside of the little fat man's bed. This was the little fat man's little girlfriend!

I go!

When did this little fat man become so bold that he dared to take his girlfriend to the dormitory to spend the night? And how did this little fat man hide this from the dormitory aunt?

You must know that the management of this dormitory is very strict.

I told you to seize it, why can't you hide it! The little fat man was speechless, and then he quickly smiled and said: Boss, isn't it Yingying and the others who are timid? The northwest wind is howling outside and they can't sleep, so they come to our dormitory. Got it!

Qin Yuanqing was speechless.

How long has this northwest wind been blowing? It’s not the first time. How come I could sleep before but couldn’t sleep tonight?

Then in Qin Yuanqing's shocked eyes, Liu Feng and Zhang Jie each showed a shy face on their bed.

I go!

These guys must have had too much fun, they even brought their girlfriends to the dormitory to spend the night!

Isn’t it appropriate for me to come back?

Qin Yuanqing put his computer and schoolbag on his back, said that Jingtian would come to pick him up, and ran away!

These guys won't come to exchange at night!

Qin Yuanqing had to think evilly that the three of them were in the same dormitory and they were all familiar with each other. . . . . . . Qin Yuanqing quickly slapped his face. When did he become so evil? How dare he think about such a thing!

Absolutely evil!

It’s only been a while now that I’m no longer innocent! !

No!

He is still a good boy! ! It's just that the little fat guys have become bad!

Qin Yuanqing thought so firmly in the northwest wind.
