The number 0 is a major turning point in mathematics.❗️
Let's think about it.
The numbers we use every day, like "0,"
In fact... it took humans 4,000 years to recognize it as a "real number."
.
Why is it so long?
.
The answer is
Early humans never thought that "emptiness" should be a number.
.
Back more than 3,400 BC.
Sumerian and Egyptian times
Numbers are only made for the "count of."
.
One sheep.
Two sheep.
But without any sheep?
Those of that generation will answer, "No sheep."
Not "0."
.
Because for them,
nullness = nullness
It's not "the amount of absence."
So 0 doesn't have to happen yet.
.
More than 1,000 years have passed.
Babylonia began to run into some problems.
They use a base 60 numeral system.
And time will write more complicated numbers.
There must be a way to say, "This position is empty, not missing."
.
So a symbol came up.
Serves as a placeholder.
Or "vacancy teller."
.
But it must be emphasized that...
It's not yet 0.
Not yet a "number."
It's only "the telling body here is nothing."
.
And humans still live with this...
Over 3,000 years.
.
Until 628.
Indian land.
Born one of the world's greatest mathematical turning points.
.
A mathematician named Brahmagupta.
Write a book called Brahmasphutasiddhanta
By stating clearly that
.
"Zero is a number with its own mathematical properties, positive, negative, computable."
.
This is the first time in human history.
Where "emptiness" is raised to
Really numbers.
.
But despite how important
0 was still in India.
Not yet spread to the world.
.
Until the 8th-9th centuries.
In the era, Thai land was still in the end of Dwaradi.
About 400 years before Sukhothai.
.
An Arab wise man named
Muhammad ibn Musa al-Khwarizmi
(The name became "Algorithm")
Leading Hindu-Arabic numerals 1-9 and 0
Let's write math texts systematically.
.
And those texts.
Is the bridge connecting 0 from India.
Into the Western world.
.
Then, in 1202,
Famous mathematicians of Europe
Leonardo Fibonacci
Write a book, Liber Abaci.
Declare that
.
"With the 9 numbers and with the 0 notation, we can write any number."
.
This book makes Europe
Discontinued Roman numerals
There are no zeros, there is no location system, and it is very difficult to calculate.
.
What's more,
It is the point that makes
Mathematics, Science, Engineering, Finance and Technology
Grow up by leaps and bounds.
Because the world had a "numerical system suitable for computing" for the first time.
.
If the world doesn't have 0
There will be no calculus.
No physics.
There is no algebra.
There's no computer.
No AI.
And of course,
There will be no world of engineers as we see it today.
.
From what once humans believed
"priceless."
Become the foundation of human civilization.
.
And it shows us that...
Sometimes emptiness is the most important key to moving the world forward.
