Charge and field

The elementary particles come in two types, charge and field.
Mass is charge, gravity is field.
(+) and (-) electrical charges, light or electric and magnetic fields.
Quarks are color charges, gluons are color fields.

Algebra is like charge, geometry is like field.
Algebra operates in the boundary provided by geometry.

Analytical brain performs algebra, while emotional brain provides geometry.
Although the brain hemispheres tend to specialise to a degree, they can perform both tasks.
Like the elementary particles, brain hemispheres also divide into parts.
The frontal lobes are for higher functions like planning.
The higher functions form a weak field of influence on the brain.
They only control the available free parameters, thus acting like a donkey leading a camel herd.
Mass/Gravity are the higher functions of the universe, forming it's overall shape.

A town is like charge, it's villages are like field.

A cat in the wild holds it's territory by random inspections, thus forming a field of influence.

In ATON, charge is like ESet, field is like HSet.
