The History Of Zero
The history of zero
One century after the Mayans...
Romans were also the one who invented numeral, but there is no zero in
The symbol for the number zero is "0"
The number zero is...
* a non- negative integer of the minimums
* a non-positive integer of the maximums.
* a whole number
* a even number
But it's NOT...
* a positive number
* a negative number
Who invented the zero number?
Once upon a time there was no zero.
The modern 0 symbol was invented in India in the 6-th century, used later by the Persians and Arab and later in Europe.
In thermodynamics, absolute zero is the theoretical lowest possible temperature.
0 is also the lowest for the pH scale in chemistry.
The melting point and freezing point of water are zero in the Celsius degree.
Music makes our life much better and zero is also a major part in the notation- "The Rest".
In the ancient, People think zero is a point of the world because you cannot around it.
It is always between the two who are opposite. Zero has been used in Zen, magic theory and other areas in metaphysics.
Zero is an important number; perhaps the most important.
The meaning of zero is very deep, so deep that we might never understand.
Thank you for watching!!
The number zero was one of the last numbers invented because the ancient Egyptian never used them and not many other countries at the time used math.
We are so accustomed with seeing the perfect circle, the zero that we cannot imagine it had to be invented.
The invention of zero was a real revolution.
"Zero" has many concepts in different areas.
At first, it could be the lowest number, could be the biggest number, or could be nothing.
How did they survive without zero?
How could they tell when all of their money was gone?
Their pockets were empty.
They had words for kind of situation: "My pockets are empty".
This concept is obviously related to numbers
(no coins, when one coin was slightly better situation).
But, you don't need an actual number zero,
when it is not part of your counting system.
They obviously had words for 'none' or 'nothing' but there was no Roman numeral for zero.
Similarly, in most cases,
you can do without negative numbers.
You need them to describe the situation in which your own money or other things that is countable, or when you measuring some thing's length.
You can ignore negative numbers,
just as the Romans had no use for a number zero.

Their numbering system was not transmitted to other people because of its peculiarity: the first group (that of the units) was not made of 10, but 60 figures.
Arabs had invented the "zero” during the 4th century BC.
That corresponded to our system of time counting:
1 minute = 60 seconds
1 hour = 60 minutes
To make sure you understood that the space was really empty there, they put a little raised dot.
Well dots are easy to miss, so to make it a little blacker, the scribe would wiggle his pen around a little, which sometimes left a little hole in the middle of a small circle.
We see that the Arabs used the function of the zero that we know today, but they did not say it was a number.
Hindu Savants invented too the figure "zero".
They also invented the position numbering.
In today's modern mathematics...
We have become used to zero as a number.
It's hard to believe that most ancient number systems didn't include zero.
The Mayan culture may have been among the first to have a symbol for zero.
The ancient Egyptians, Romans, and Greeks had no symbol for zero.
It is understandable in some way. I'm just giving out an idea to have a better view of the meaning of Zero.
The Rest perfectly link up the althorn part and the bass part in music, sounds like it is effecting like the effect of zero between the positive and negative parts in mathematics.
