** Circular Geometry**

Why doe those watersoundimages appear in liquid in a circular form?

**Properties of the circle in regard of watersoundimages**

Also a circular disk can be regarded as a three-unity. A disk is the area between the counterparts of perimeter and midpoint.The interaction between those opposites take place in this shape (disk, cilinder, sphere).

A circle has a circumference and a centre: an outside boundary, and a middle that is at equal distance of each point of that circumference.

The centre is a point (with no dimension), the circumference is a line (one dimension) that borders a rounded shape, a disc ( wich is a second dimension) and turns back in his own tail so that there is no ending (nor begining). You could walk on this circumference infinite long. The centre, without dimension, is infinite small.

So, in a circle we have two infinities in complete different ways, in opposite meanings, in a polar sence.

The relation between the centre and the circumference can be described in other ways. For example in space: how can we move between them? Best known is going straight from the centre to (one place on) the circumference. Then we follow a radial, between centre-point and curved rounding.

Or can we go to all the places of the perimeter at one time? With more people yes, in a ring, like a circular wave. And if everyone(all at the same speed please), by the meeting of the circular boundery, perpendicular to him turn back, we will all meet again. Where? Right, all of us right in the centre. Self-evident you can say, nevertheless this will only happen in a circle.

The water in our vessel knows this centre very well: radials and circlewaves start from it, reflect perpendicular on the circumference and return right to the centre.

Straight radials and curved circumference meet each other with their "polar characters", work together, and create many patterns. Between concentric circles appear straight sided polygons, near the outside boundery polygons with rounded sides. Regular arranged circles inside the total circle influence each other and create new patterns. Sometimes two opposite curved lines even create straight lines, therefore they have to work together in an extreme equilibrium!

Three-unity processes in the circle:

- in the disk-plane happens the interaction between peripheral en central forces;

- a rectilinear radial moves between a (mid-)point and a curved closed line;

- a disk-plane between an all arround, envelopping bounderie outside and a sourcing centre inside;

- over the disk are moving centrifugal forces from the centre, and centripetal influences to that centre from the periphery;

- expanding and contracting phenomena meet over the disk;

- the interaction is dynamical, in a well-balanced equilibrium between rectilinear radials and curved arcs;

- a differentiating harmonical arrangement between all those polar influences, a teamwork leading to a well-balanced composition;

- a symphony ...
