"The unitary element equals God"
Aristoteles

I read a book that has fascinated my imagination. Its name is "El hombre que calculaba" (I´m pretty sure that there must be an English version whose name I ignore) and it was a book about math and life. In it, a great mathematician, Beremir Azis (or I don´t know what the hell was his name) reflected great wisdom in the mitological Persia.

One of his great reflexions was about the concept of number and their great consecuences. He stated that the number was an estratification of the concept of quantity. Any beast is capable with a single glance to determine if there has been a significative change in the quantity, but just an inteligent person could "count" and determine the "number" of elements. Therefore, the number arises as the necesity of cuantifying the mental process of counting and to assign a value, the "quantity".

Numbers arise and all their relationships in the big science of mathematics, doctor of all sciences and distinguished daughter of filosophy, mother of all sciences.And all numbers present their beautiful and gorgeous features, their infinity does not rest them the spark that each one of them has.

One of their features is that they can be expressed in several ways:

2 = 1 + 1
12 = 3 * 2 * 2 = 3 * 2^2
8 = SR(64)
5 = 2.5 + .5 + 4/2

And so on ...

Taking into consideration the natural procedures of human logic, synthesis and analysis, the ways of expressing numbers vary infinetly
in both directions.
For example, given that:

.5x + .25x + .2x +.05x = x

The previous equations shows that the sum of the parts of a everything always is going to be equal to the unit. Therefore if we consider that everything has to do with everything, the sinergy, summatory, fusion or synthesis of the elements of the universe should be equal to a superior unit, that represents the wholeness of the universe. Then the explanation of:

"The number that represents the unit is God"

Following the inverse pattern, analysis, you can "analyze" or divide the unit in many ways, but you can mainly do two, uniformly or variably. Percentages represent a variable division.

Uniformly is represented by the arimetic operation: division. This one enables to cut the unit in equal parts, giving them uniformity without pondering any of them.

Among all posible divisions, there is one worthy of mention: by two.
This represents the least possible problems for human understanding.

And this is how duality is defined, a unit represented by the most simple division, where the totality of a unit is fractioned in two parts that aparently struggle with each other but equilibrate forces in a spiral of constant fusion and give form to the unit. The best representation of the most simple division is the so famous chinese symbol, yin-yan.

The black part goes into the white one and a part of the white does the same with the black. A little bit of both is on the opposite side.
Yin-yan by definition is the grafic representation of the most simple divition. Summatory of both areas gives as result the totality of the circle´s area which represents the unit.

Duality (most simple division) represents the unit as two parts apparently distincts.
