Omnipotent Data

Chapter 382

Five minutes later, Classmate Chali ran back out of breath.

"Great God, I borrowed my classmate's library card, you use it first." Chali panted and handed a library card to Cheng Nuo.

Cheng Nuo took it and smiled, "Thank you."

"No, no thanks." Chali hurriedly waved his hand, scratched his head, and said to Cheng Nuo with a smile, "Great God, let's go in together."

"go!"

The two went in smoothly, first found an empty table to put down their school bags, and then under the guidance of Chali, walked to the math section of the library.

Ten rows of bookshelves are densely packed with books related to mathematics, and there are hundreds of thousands of books.

The scope 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!

Restraining the excitement in his heart, he took a deep breath, step by step searching for the books he needed.

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

As for that new project, Cheng Nuo guessed that 80% of it should still be a subject in the field of geometry.

Among all branches of mathematics, geometry is not Cheng Nuo's best field. Of course, as far as Cheng Nuo's ability in geometry is concerned, it is more than enough to be Professor Fresnel's assistant.

But Cheng Nuo's goal is not so narrow.

Cheng Nuo has to charge more when he has time.

"Modern European Geometry"

"Affine Differential Geometry"

"Ackerman's Turn to Geometry"

…………

Cheng Nuo quickly turned on the harvest mode, and when he saw the book of interest, he pulled it out directly from the shelf.

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

On the way back to the desk, Cheng Nuo happened to be the location of the book collection in the number theory area. After a light glance, he was suddenly attracted by the name of a book: "The Development and Recent Situation of the ABC Conjecture".

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

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

While chewing, there was an expression of incomparable intoxication on his face.

Classmate Chali wiped off the sweat that didn't exist on his forehead, and muttered in his heart, "The great **** is the great god, and even the way the library reads is so different!"

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

Even with numbers in English, Cheng Nuo's reading speed is not slower than usual.

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

With the passage of time, Cheng Nuo's geometry skill points are constantly soaring.

Geometry is considered to be the oldest among all branches of mathematics. From the period of the four ancient civilizations to the present, I am afraid it has a history of more than three thousand 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 world, is afraid to say that he can thoroughly study this subject, let alone Cheng Nuo.

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 the sadness.

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

Cheng Nuo was in such a state. He was already in a good mood. After reading three or four books on geometry, he felt more happy.

Opposite Chali looked up at Cheng Nuo's face from time to time while reading a book.

Seeing Cheng Nuo's rising mouth corners, classmate Chali couldn't help being even more bewildered.

After another period of time passed, Cheng Nuo had been tired of reading books on geometry, so he took the thin "Development and Recent Situation of ABC Conjecture" in front of him.

Previously, the names of the ABC conjecture have been well known, but the difficulty of it has never been seriously studied.

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

Even compared to Goldbach’s conjecture, the difficulty alone is a level higher.

Now, Cheng Nuo wants to really experience it.

Turning to the first page, Cheng Nuo glanced through the catalog.

Sure enough, all the books on the ABC conjecture, Ueda Shinichi is a hurdle that cannot be avoided. In this book, about one-third of the space is related to Ueda Shinichi.

Compared with famous members of the mathematics conjecture family, such as Riemann’s conjecture, Goldbach’s conjecture, twin prime conjecture, and the (proven) Fermat conjecture, the "qualification" of ABC conjecture is very It's shallow, because all the other guesses are "old predecessors" over a hundred years old.

This conjecture was put forward in 1985. At that time, the reputation was not obvious, but after later generations noticed the importance of this conjecture, it entered the field of vision of mathematicians in the world.

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

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

Obviously, there are infinitely many groups of positive integers satisfying this condition, such as (3, 8, 11), (16, 17, 33). In order to elicit the ABC conjecture, take (3, 8, 11) as an example, and do a simple calculation of "three steps":

① Multiply A, B, and C (the result is 3×8×11=264);

② Perform prime number decomposition on the product (the result is 264=23×3×11);

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

Now, compare the larger of the three numbers A, B, and C (namely C) with the result of step 3. You will find that the latter is greater than the former. If you just find some other examples, 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 if the result of ③ is added to a power greater than 1, the number of counterexamples will change from infinite to finite. U U Reading www.uukanshu.com

Simply put, the ABC conjecture is a conjecture that allows counterexamples.

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

After reading the title, Cheng Nuo took out a draft paper and wrote and painted on it for a while.

Half an hour later, he could only sigh, "It's difficult!"

Sure enough, this kind of world-class conjecture is not something coquettish.

This conjecture is really interesting!

No clue, no clue.

Cheng Nuo didn't read the analysis of this conjecture by several mathematics tycoons later in the book. He tried a wave alone, but found that the whole line was defeated.

He could not find any breakthrough to overcome this conjecture.

It's uncomfortable!
