Atom

All entities are made of a smallest unit, an atom.
Chemical elements are made of atoms.
Carbon based life is based on cells, the atoms of life.
Species are made of individuals.
Galaxies are made of stars.
Universe is made of galaxies.

Atoms are made of a core, a shell and a core-shell relationship.
Cell core is made of genetic material.
Cell shell or skin is made of porous tissue made of proteins that allows bothways filtration.
Cell's inside is a dynamic environment, reflecting it's outer environment, that digests the food eaten, defends against invaders, does maintenance, creates heat and many other tasks.
The know-how is stored in the core, which is in a periodic swirling motion like a beating heart.
This motion is both inwards and outwards so that there is loop.

Like galaxies, all atoms spin in a preferred direction, left or right handed.
This spin creates a moment and allows atoms to line up to make networks.
Higher spins create inner moments.

For contained smooth motion to exist, a minimum of 2 dimensions are required.
The smallest sphere is a circle.
This is demonstrated by the closure of complex numbers by 2 dimensions {+-1, +-i}.
Contained motion defines the entity, e^i*a.
The first motion that emerges is that of communication or exchange.
i*i = -1
Sqrt[-1] = i

In the wild, all populations have predators until the top ones.
Even the top ones have predators in another context.
A relatively contained Predator/Prey relationship oscillates around a mean and defines both species.
Without a predator, a species would not evolve as fast and becomes extinct easily.
Predator eats the weak and the sick and thus refines the genetic pool of the prey.
Thus a good PP relationship defines an entity out of it's base.
