An Uncertain Determinism

A quark withing a particle
of the nucleus of an atom
in a molecule of substance
of a rolling snooker ball
is neither here nor there
and not directional.

So are they all.

They dance in random orbits
where the chance that each is where
their fellows in the prodding
of the chalky, pushy cue
are in line with its pointing
is no more than a smattering
twixt my lucky streak continuing
at the table in the corner
and the quite unlikely sound
of another player saying,
‘I’m buying the next round.’

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?


Back with a charged computer and taking up where I left off, I imagine many of you spotted the theme of my last post ‘Elpee!’ was Planck’s Length, L­­­p­­­ and the strange forces that seem to bind the universe together at the same time as preventing it from collapsing in on itself.

You did? Wow!

Anyway for those who might not have done:

The concealed theme in the poem is the four fundamental interactions or forces of Quantum Mechanics (QM): electromagnetic, gravitational, strong, and weak, which make up our universe. They can be hard to understand, as is QM generally, so I pictured them as a flock of starlings.

Electromagnetic radiation is the colours thrown between the sky and starlings wings (by which they know one another and their world).

Gravity is the distant longing, drawing the flock as one (Newton’s apple to the earth).

The strong interaction draws mate to mate, binding families and roosting birds into groups (atoms, molecules, compounds, you).

The weak interaction is the short range interaction between birds, stopping them crashing together but not strong enough to break up the flock (stabilising those groups drawn by the strong interaction).

LP is Planck Length. A starling’s wing-flutter and flight swirls make its position, size and velocity uncertain. If there were no limit to this, if their size could be infinitely small, the flock could collapse or evaporate to nothing. Max Planck, faced with a  problem involving radiation, found there was a limit to the smallness of things; a fundamental length or grain size, even to space, below which the laws of physics will not take us. This length is known as Planck’s Length, or LP, the smallest distance that can be measured.

Because length is effectively granular in this way, so are all those things that depend on it. Speed of travel is length (distance travelled) divided by the time taken, so time is granular in the same way; it literally ticks on in tiny portions of Planck Time (Tp), the time light, the fastest thing in the universe, takes to travel one Planck length. Mass, temperature, and electric charge also share this granular nature.

I hope you find this difficult to follow because physicists do. There is something very strange going on – a conflict between the laws governing the very small and the very large. The sums do not work. When particles, which are seen as the focus or points of action of waves of energy, come together en masse, the Earth and Moon, or an apple falling from a tree, their gravity bends and contracts the space between them and brings them together. Physicists can calculate the mathematics of this and define its laws, but these same particles on their own, in their own tiny inner space do not follow these laws. The laws we find governing the very small and the very big do not agree. Somewhere we have got it wrong.

No poem this time, but I am working on it. A murmuration of starlings is one way of looking at the cosmos with the starlings representing particles of matter in fields of energy. Each starling or particle is a focus or point of action of its field of energy.

There may be another way, a quite different, far more relaxed view, in which starlings are replaced by ‘Eddies in the Stream’ which I shall post in a couple of weeks. If you want to get ahead of me there are two fun and interesting ‘You Tube’ illustrations by ‘Physics Girl’ Dianna Cowern here and James Dann here. If you watch James Dann’s setup closely there is something to be seen that he does not mention.

See you in two weeks.
