OrderAny arrangement of things is an order, and a different arrangement of the same things is a different order.

The “aspect of communication engineering”, here referred to, had to do with the technical problems with distinguishing ‘message’ (the wanted orders) from ‘noise’ (the unwanted orders), in telecommunications.
We see that right from the start, statistical mechanics, and its application to thermodynamics, is, by conscious, deliberate definition,
The degree of disorder mentioned above is by this definition to be understood as the negative of the amount of information as Wiener defines it. This quantity is Entropy.
In short, if liquid is particulate, it is supposed (rather than observed) to behave stochastically, and its entropy must increase with time.
Clearly, there has been a great deal of supposition going
on here!
The suppositions may be correct, but the hypothesis that all this supposition is intended to support has not, to my knowledge, been rigorously tested. The study suggested here, of water flow in flow forms, may offer a test. |
Water moving in a flow-formappears to be acted on at the macroscopic levelby mechanical forces in addition to those at the microscopic level considered by statistical mechanics and thermodynamics. Gravity is surely at work, and there are certainly periodic forces associated with wave-creation and propagation. Electrostatic forces, from friction between water and flow-form, can be expected. Resonance seems very much in evidence. ![]() The sketch above attempts to depict a way to study the behaviour of the surface of water oscillating through a flow-form. The light source should be small, and bright, and shine its light on the water's surface in such a way that its reflection from the surface are caught as a light-pattern on a translucent screen. This will allow the pattern to be photographed from behind the screen by a camera set normal to it, which should eliminate perspective problems. I guess that the pattern is bright where light has reflected from the surface, and dark where light has refracted down into the body of the water, which, according to ordinary physics, has all to do with the critical angle, which in turn implies that we are having as much to do with the orientation of planes—those “osculating” ( kissing! ) planes that are supposed to be tangent to the water's surface—as we are with position. It may be that we will have to do with both of the polar aspects of the surface. A CaveatWe need to bear in mindthat a surface is a mathematical entity. By definition, surfaces are continuous. But we are positing that a mathematical entity can interface particulate, physical media, which by definition are discontinuous. We should therefore be prepared to entertain the serious possibility that such a mathematical surface cannot physically exist. Strobed SamplesThe material bulk of a flow form – its stone, clay, ceramic or composite – is not intended by design to move in response to the water oscillating between its basins, but it must move, to some degree.If a strain-guage were to be used to detect this inevitable movement—which would be as rhythmic as the water's movement, and share its periodicity—its output could, conceivably, be arranged to trigger a photograph at a specified moment in each swing-cycle. This would in effect be strobing the water's pattern. An arrangement like the one in the diagram below might work. ![]()
The slight ‘rocking’ of the form would deform the rubber base to which it is attached, and with it the guage. The output waveform may not be quite as simple as the near-sinusoid depicted here! The pattern does not appear to the eye to repeat exactly, but it may nearly do so, in the sense that the samples might change from one to the next in some regular, incremental fashion, a bit like precession—or the changes might be chaotic, which, it must be stressed, does not imply that they are random (i.e., stochastic). Strobed sampling should cast some light (sic) on the issue. |

Interpretation of the Patterns (1)Which geometry applies? Does any apply?Light is often said to radiate: it is thought to travel as “rays”, which are lines, and to come from a source, or centre, which is a point.In other words, light is conflated with geometry and number, despite the fact that neither geometry nor number is light. Curious juxtapositions, like this one, of concept and phenomena are ubiquitous in physics, and rife in exact science generally. Geometry may have some kind of incidence with light,
