Chapter 379 Uncomfortable!
382 chapter

Five minutes later, classmate Chari ran back panting.

"Master, I borrowed my classmate's library card, you use it first." Panting heavily, Cha Li handed a library card to Cheng Nuo.

Cheng Nuo took it and said with a smile, "Thank you."

"No, no thanks." Cha Li hurriedly waved his hands, scratched his head, and said to Cheng Nuo with a smile, "Master, let's go in together."

"go!"

The two of them went in smoothly, first found an empty table and put down their schoolbags, and then, under the guidance of Zha Li, they walked to the mathematics section of the library.

There are ten rows of bookshelves, all of which are densely packed with books related to mathematics subjects. There are at least 10,000+ books.

The coverage covers almost all kinds of books from easy to difficult in all branches of mathematics.

Standing in front of the bookshelf, Cheng Nuo was dazzled.

This... is simply heaven on earth!

Suppressing the excitement in his heart, he took a deep breath and searched for the books he needed step by step.

In three or four days, he will return to the office to tackle new projects with Professor Fresnel.

As for the new project, Cheng Nuo probably guessed that it should still belong to the field of geometry.

Among all the branches of mathematics, geometry was not Cheng Nuo's best field.Of course, Cheng Nuo's ability in geometry was more than enough to be Professor Fresnel's assistant.

But Cheng Nuo's goal was not so narrow.

Taking advantage of the time, charging more is what Cheng Nuo should do.

"Modern European Geometry"

"Affine Differential Geometry"

"Ackermann Turns to Geometry"

…………

Cheng Nuo quickly turned on the harvesting mode, and when he saw a book he was interested in, he pulled it out of the shelf.

He didn't expect to become a fat man in one go, and when he saw that the books in his hand had piled up in a high pile, he stopped harvesting.

On the way back to the desk, Cheng Nuo happened to find the book collection in the number theory area. After a quick glance, he was suddenly attracted by the title of a book: "The Development and Current Situation of the ABC Conjecture".

It happened that yesterday I listened to a lecture on the ABC conjecture, so as soon as Cheng Nuo saw the name, he subconsciously pulled out the book and put it in his "book pile".

So when Charlie came back with two books, what he saw was that Cheng Nuo was chewing on a stack of books more than half a meter high.

While chewing, there was an intoxicated expression on his face.

Student Chali wiped the sweat that didn't exist on his forehead, and muttered in his heart, "The Great God is the Great God, even the way of reading in the library is so different!"

After thinking about it, he sat across from Cheng Nuo and picked up the book to read.

Even though it was all in English, Cheng Nuo's reading speed was not slower than usual.

A book with more than 100 pages can only last half an hour under Cheng Nuo's hands.

As time went by, Cheng Nuo's geometry skill points continued to soar.

Geometry is the oldest of all branches of mathematics.From the period of the four ancient civilizations to the present, I am afraid that it has a history of more than 3000 years.

Thousands of years of accumulation and development have made geometry a very advanced subject.

Even Professor Fresnel, who stands at the top of the world's mathematics field, would not dare to say that he can thoroughly study this subject, let alone Cheng Nuo now.

He is like a sponge in the vast sea, absorbing the water of knowledge as much as possible.

Mathematics makes people happy.This sentence is really good.

When you are sad, take out a math book and study it carefully, which will make people forget their sadness.

When you are happy, take out a math book and savor it slowly, you will be happier!

Cheng Nuo was in such a state. He was already in a good mood, but after reading three or four books on geometry, he felt even happier.

On the opposite side, while reading a book, Cha Li looked up from time to time to observe Cheng Nuo's face.

Seeing the corners of Cheng Nuo's mouth rising more and more, classmate Zhali couldn't help but become even more confused.

Some time passed, and Cheng Nuo got tired of reading geometry books, so he casually took the thin "The Development and Current Situation of ABC Conjecture" in front of him.

The ABC conjecture has been widely known before, but its difficulty has never been seriously studied.

But it is recognized that, in addition to six of the seven millennium conjectures that have not yet been solved, the ABC conjecture can be ranked in the second echelon.

Even compared to that Goldbach's conjecture, it is even higher in terms of difficulty.

Now, Cheng Nuo wanted to experience it for real.

Turning to the first page, Cheng Nuo briefly browsed the catalog.

Sure enough, for all the books about the ABC conjecture, Ueda Shinichi is an insurmountable hurdle.In this book, about one-third of the space is related to Ueda Shinichi.

Compared with famous members of the big family of mathematical conjectures, such as Riemann conjecture, Goldbach conjecture, twin prime conjecture, and (already proven) Fermat conjecture, etc., the "qualifications" of ABC conjecture are very Shallow, because the other conjectures are "old-timers" who are over a hundred years old.

This conjecture was proposed in 1985. It was not well-known at the time. However, after later generations noticed the importance of the conjecture, it entered the field of vision of the world's mathematicians.

In fact, the content of ABC conjecture is the same as Goldbach’s conjecture, and it is not difficult for ordinary people to understand:

The ABC conjecture is for groups of positive integers (A, B, C) that satisfy two simple conditions.The first condition is that A and B are mutually prime, and the second condition is that A+B=C.

Obviously, there are infinitely many groups of positive integers satisfying this condition—for example, (3, 8, 11), (16, 17, 33)....In order to draw out the ABC conjecture, take (3, 8, 11) as an example, and do a simple "three-step" calculation:
①Multiply A, B, C (result is 3×8×11=264);

②Decompose the product into prime numbers (the result is 264=23×3×11);

③Multiply all the different prime numbers in the prime factorization (the result is 2×3×11=66).

Now, compare the larger of the three numbers A, B, and C (that is, C) with the result of step 3, and you will find that the latter is greater than the former.If you look for some other examples at random, you are likely to find the same result.

But this is not a rule, there are countless counterexamples, such as (3, 125, 128), etc., but adding a power greater than 1 to the result of ③, the number of counterexamples will change from infinite to limited.

In simple terms, the ABC conjecture is a conjecture that allows counterexamples.

Therefore, the method of using supercomputing to find counterexamples to prove conjectures is not applicable to this problem at all.

After reading the topic, Cheng Nuo took out a piece of draft paper and wrote and drew on it for a while.

Half an hour later, I could only sigh, "It's hard!"

Sure enough, this kind of world-class conjecture cannot be achieved by just some glamorous craftsman.

This conjecture is really very predictable!
No clue, no clue.

Cheng Nuo didn't read the analysis of the conjecture by several mathematics experts in the back of the book. He tried a wave alone, but found that he was completely defeated.

He couldn't find any breakthrough at all to overcome this conjecture.

Uncomfortable!
