Chapter 373 Giant Current River Breakthrough!
Institute of Mathematics, top floor.

Lin Ke sat at the conference table with a helpless expression, while the mathematicians sat at the table one by one, sitting upright.

The mathematicians didn't really fight just now. When Lin Ke was thrown into the air, they quickly pulled him back, like elementary school students who made a mistake.

But Lin Ke was not angry either.

Compared with many experts and professors with human faces and animal hearts in previous lives, the mathematicians in front of them can be regarded as pure and pure.

"Actually, for rational numbers and irrational numbers, in simple terms, I think this way..." Lin Ke didn't write any ink, and started to calculate directly.

"The difference between rational numbers and irrational numbers is as follows. I think the most important point is that rational numbers can be written as finite or infinite recurring numbers, while irrational numbers can only be written as infinite non-recurring numbers!"

As soon as he finished speaking, the mathematicians fell into deep thought.

To distinguish whether it is circular or not?
After careful consideration, I have to say that Hezhen is a more differentiated and recognizable classification.

Lin Ke continued:
"All rational numbers can be written as a ratio of two integers, but irrational numbers cannot be written as a ratio of two integers, and the ranges of the two are different. A reasonable number set is an extension of the integer set. The four operations, addition, subtraction, multiplication, Divide. Unobstructed in the set of rational numbers."

"Rational numbers and irrational numbers are collectively called real numbers by me. Complex numbers other than real numbers are called imaginary numbers by me. Real numbers and imaginary numbers are also called complex numbers..."

Lin Ke spoke extremely fast, telling about "numbers".

Complex numbers, real numbers, rational numbers, integers, fractions, odd numbers, even numbers...

Layers of logical and rigorous classification diagrams about numbers are slowly unfolding in the eyes of mathematicians.

This is a complete and effective mathematical system!
Generally speaking, systematic things are not formed from top to bottom from the beginning.

In science, it is often a hammer here and a stick there, some research results here, some research results there, and finally these bits and pieces of results converge into the final system.

Then discover the previous gaps in this more comprehensive system.

Like the periodic table of elements.

It doesn't mean that there is such a thing at the beginning, and then start the experiment with hydrogen.

It was only after experimenting with scattered elements that the law was discovered.

The same is true for mathematics.

Some people study positive integers, and after further research, they find that there are also negative integers and decimals. This step by step constitutes one of the high-rise buildings of mathematics.

Science, is bottom-up.

Therefore, when Lin Ke proposed a complete classification concept from top to bottom, mathematicians were surprised.

Their terrifying brains immediately started various thinking collisions, and the meeting room immediately fell into a small magical storm.

"Integers, prime numbers, analytic functions..."

"This is one of the cornerstones of mathematics!"

"I feel that suitable disciplines can be extended from each category!"

"Not only that, a legend may be born in each category!"

The mathematicians discussed with great interest.

Juliuhe also asked Lin Ke at this time.

"Mr. Lin Ke, you told me a word before, it seems to be pronounced...'π'?" Juliuhe didn't remember much about other things, but she remembered mathematics very clearly.

"π?" Lin Ke nodded: "I realized that you haven't invented such a thing as a compass, have you? This is a tool for drawing circles. As for π, it was born from the method of cutting circles..."

Lin Ke began to explain π, and used elements to outline the shape of the Greek letter "π" in the air.

π is pi.

In the previous life, π was the ratio of the circumference of a circle to its diameter, generally represented by the Greek letter π, and it is a mathematical constant commonly found in mathematics and physics.

π is also equal to the ratio of the area of ​​a circle to the square of the radius, and is a key value for accurately calculating geometric shapes such as the circumference of a circle, the area of ​​a circle, and the volume of a sphere.

In analysis, π can be strictly defined as the smallest positive real number x satisfying sinx=0.

But in Nassang, there is no such concept as pi.

So, this will be brought up by Lin Ke.

Logically speaking, Nasenge and the previous life are two completely different universes.

But mathematics, a discipline about pure numbers, will not change.

Physics, chemistry, biology, history, astronomy, etc., many things will change with the changes of the universe, galaxies, and planets.

But math doesn't.

Under certain conditions, one plus one equals two, but not three.

It doesn't matter which universe you change to.

But physical chemistry and the like, perhaps just a slight change in the laws of the universe, will change beyond recognition.

Therefore, mathematics is the cornerstone of science.

But in the previous life, the definition of irrational numbers was infinite non-recurring decimals.

The most representative of these is pi.

Why are so many people trying to prove that pi is circular in previous lives?
For example, on August 2, 21x8 in the previous life, a Swiss researcher used a supercomputer for 17 days to calculate π to 108 trillion digits after the decimal point, and still found that it is infinite and non-recurring.

At present, this is an endless number.

But once someone discovers that π is cyclic, or finite, the mathematical algorithm will collapse from the bottom, which will affect every discipline of the entire science.

For example, high numbers based on infinite approximation thinking such as calculus are based on the circle cutting method.

The same is true for physics, there will be problems in the formulas of the gravitational field equations of the general theory of relativity, and the same is true for Coulomb's law.

All kinds of conservation theorems will also become invalid because of this, the scientific buildings of the last 400 years since the time of Newton will be demolished and rebuilt, and the entire human history will be rewritten.

Therefore, when Lin Ke proposed π, the eyes of Juliuhe in front of him burst into a frightening light.

In front of her, a circle outlined by white light appeared, and in just an instant, tens of thousands of lines appeared on the circle to divide the circle into equal parts.

And this number is still increasing. In just a dozen seconds, the circle in front of me is filled with those lines, and I don't know how many parts it has been divided into.

"This...this is..."

The strange shape of Juliu River attracted other mathematicians, and they looked over one by one.

And in the process, the aura on Juliuhe's body became more and more intense, and the white light that shot out from his eyes became more and more astonishing.

Lin Ke and the others didn't move. They stood there and watched. Many researchers in the Institute of Mathematics were startled by the breath of the Juliu River. Countless elements in the entire small space rushed towards the Juliu River.

A symbol appeared in Juliuhe's glowing eyes, it was "π"!
"I understand!"

Juliuhe let out a soft drink, and the circle that had been divided countless times in front of her eyes dissipated immediately, but her body floated up.

Lin Ke raised his eyebrows: "This is... a breakthrough?"
