Eddies in the Stream

When rain clouds rise from oceans
like sea-waves in the sky
from sea to land and onward,
to hills and mountains upward,
to pour down from up high.

Where storm-rains lash the heather
to soak in moss and peat,
where dark deer-runnels ooze and drain
and ocean’s loss is nature’s gain,
for streamlets swell to run again
to rivers pure and sweet.

Where alders dip above the run
and boulders break the stream,
and eddies, whirling as they go,
dance with each other in the flow
like dancers in a dream.

They turn and fill and ebb and flow –
and catch the eye so well –
small points of action in the stream,
the focus of the swell
as though the river’s swelling run
is focussed in their spin and turn
and river, sea and rain are one;
a cosmic carousel.

We spin in busy circles,
swirled in life’s foray
while the great stream flows forever
to an ocean that is ever
beyond this little day
where the depth and breadth and wonder
of this turning cosmic reel
is just a little bay
in which the eddies play.

Two weeks ago I suggested that you watch two interesting ‘You Tube’ illustrations of eddies and harmonics:

‘Physics Girl’ Dianna Cowern here, and James Dann here.

If physics girl held her plate in a running stream instead of a still pool the eddies would be relatively still while the stream runs powerfully on.

If you watch James Dann’s setup closely you can see flickering waves within the ones he shows. Later, when he shows the first harmonic, at the wave’s highest and lowest points, top and bottom, there are nodes in the string outline which are not part of the demonstration. You can capture them, as well as the flickering internal nodes and harmonics, by pressing pause at various points. They can be seen as wobbles in the slow motion capture by the high-speed camera. They happen because the  string is never fully at rest before the demonstration starts. Dann moves from one example to the next without letting it fully settle down, but even if he did there would still be a fine wave background due to circumstances outside his control, an in-built uncertainty.

We are used to the idea that energy and matter are compatible and can be transformed, one into the other (E = mc2). Matter has been described as the collapsed waveform or point of action of waves of energy – the ‘hit’ where energy makes its impact. It forms interactive, bound clusters of these points of action which we call particles, atoms, molecules, compounds, chairs, tables, you.

Another word for the particles of which all things are built is nodes, from the latin for knot. It is as though energy is a vibrating violin string whose action, such as playing the note C, is marked by a point at which it is held at the bridge or the violinist’s finger.

These slower, harmonic notes point to a strange possibility. Nodes have little of the energy of the string, they are points of relative inaction. If we think of particles of matter as harmonic nodes in the total cosmic energy, then they are not points of action or collapsed waveforms, they are foci or regions of relative steadiness, eddies in the stream as the stream runs powerfully on. They swirl dramatically, like points of active energy in a stream’s flow, but the stream’s energy is far greater though less visible than its eddies. It is more like the dark energy unexpectedly accelerating cosmic expansion. Seen this way particles are not points of action or building blocks, they are eddies in this expanding cosmic ball; harmonics in the cosmic wave-function.

And is this universe what Dame Julian saw in a vision? something as small as a hazelnut in the hand of God, our Father and Source of all creative energy?
