Chapter 381 Breakthrough of the Giant Stream River!

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 were not really fighting just now. When Lin Ke was thrown away, they quickly pulled him back, each one like a primary school student who made a mistake.

But Lin Ke wasn't angry either.

Compared with many experts and professors in previous lives who had human faces and animal hearts and dressed like animals, the mathematicians in front of us can be considered simple and pure.

"Actually, regarding rational numbers and irrational numbers, to put it simply, this is what I think..." Lin Ke started calculating directly without leaving any ink.

"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 cyclic numbers, while irrational numbers can only be written as infinite non-cyclic numbers!"

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

Distinguish by whether it is cyclic or limited?

After thinking about it carefully, I have to say that He Huan is really a more differentiated and recognizable classification.

Lin Ke continued:

"All rational numbers can be written as the ratio of two integers, but irrational numbers cannot be written as the ratio of two integers, and the ranges of the two are different. The reasonable number set is an extension of the integer set. Among them, the four operations are addition, subtraction, and multiplication.

Divide. There is no obstacle 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 composed of complex numbers..."

Lin Ke spoke very fast and talked about the knowledge about "numbers".

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

A layer-by-layer logical classification diagram of numbers slowly unfolded in the eyes of mathematicians.

This is a complete and effective mathematical system!

Generally speaking, things that form a system are not formed from the top down from the beginning.

In science, there is often a hammer in one place and a stick in the other. There are some research results here and some research results there. In the end, these bits and pieces of results converge into the final system.

Then we can discover the previous gaps in this more comprehensive system.

For example, the periodic table of elements.

It’s not like we first proposed the existence of this thing and then started experimenting with hydrogen.

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

The same is true for mathematics.

Some people study positive integers, and as they continue their research, they find that there are also negative integers and decimals. Step by step, they form one of the tallest buildings in 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 began to collide with various thoughts, and the conference room immediately fell into a small magic storm.

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

"This is one of the cornerstones of mathematics!"

“I feel that every category can be extended to appropriate disciplines!”

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

The mathematicians discussed it with great interest.

Juliuhe also asked Lin Ke at this time.

"Mr. Lin Ke, you told me a word before, and 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 noticed that you haven't invented something like the compass, right? This is an instrument used to draw circles. As for π, it was born from the method of cutting a circle..."

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 previous lives, π was the ratio of the circumference to the diameter of a circle, generally represented by the Greek letter π. It is a mathematical constant ubiquitous in mathematics and physics.

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

In analysis, π can be strictly defined as the smallest positive real number x that satisfies private nx=0.

But in Nassenger, there is currently no concept of pi.

So, this will be brought up by Lin Ke.

Logically speaking, Nasenger and his previous life are two completely different universes.

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

Physics, chemistry, biology, history, astronomy, etc., many things will change with the changes in 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 we change to, it's the same.

But in physics and chemistry, maybe just a slight change in the laws of the universe will change beyond recognition.

Therefore, mathematics is the cornerstone of science.

But in previous lives, the definition of irrational numbers was infinite non-repeating decimals.

The most representative one is pi.

Why did so many people in previous lives try to prove that pi is cyclic?

For example, on August 17, 2021, in the previous life, a Swiss researcher used a supercomputer to calculate pi to 62.8 trillion digits after the decimal point for 108 days, and still found that it was infinite and non-cyclic.

At present, this is an endless number.

But once someone discovers that π is cyclic, or finite, mathematical algorithms will collapse from the bottom, affecting every discipline of science.

For example, advanced numbers based on infinite approximation thinking such as calculus are based on the method of cutting circles.

The same is true in physics. Formulas such as the gravitational field equations of general relativity will have problems, and the same is true for Coulomb's law.

Various conservation principles will become invalid as a result, all four hundred years of scientific buildings since Newton's time will be torn down and rebuilt, and the entire history of mankind will be rewritten.

Therefore, when Lin Ke proposed π, a terrifying light erupted from Juliuhe's eyes.

In front of her, a circle outlined by white light appeared. In just a moment, tens of thousands of lines appeared on the circle, dividing the circle into equal parts.

And this number is still increasing. In just ten 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 behavior of the giant river attracted other mathematicians, and they looked over one by one.

In the process, the aura on Juliuhe's body became more and more intense, and the white light bursting out of his eyes became more and more astonishing.

Lin Ke and the others did not move. They stood there and watched. Many researchers in the Institute of Mathematics were alerted by the aura of Juliuhe. Countless elements in the entire small space rushed towards Juliuhe.

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

"I see!"

Juliuhe gave a soft drink, and the circle that had been divided countless times before her eyes immediately dissipated, while her body floated.

Lin Ke raised his eyebrows: "Is this...a breakthrough?"
