proposition 0.4

how about this as a working proposition:

rhythm is not a thing, not a form, not even a pattern, but a sense ?
(thus, a special case of temporality, which is the sense of dynamic, change, …)

added to
rhythm is not sonic

rhythmic is not unidimensional

rhythm is not metrically regular, or metric at all.

from teraswam to continuum mechanics, and rheology?

Could RHEOLOGY and continuum mechanics be a source of insight for the continuum limit from internet of things to teraswarm and beyond?

That, plus a form of general relativity that has to take into account the interactions peculiar to media?

Rheology (/riːˈɒlədʒi/; from Greek ῥέω rhéō, "flow" and -λoγία, -logia, "study of") is the study of the flow of matter, primarily in a liquid state, but also as 'soft solids' or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force.[1] It applies to substances which have a complex microstructure, such as muds, sludges, suspensions, polymers and other glass formers (e.g., silicates), as well as many foods and additives, bodily fluids (e.g., blood) and other biological materials or other materials which belong to the class of soft matter.

Abstract or Description

This introduction charts several of rhythm's various returns as a way of laying out the theoretical and methodological field in which the articles of this special issue find their place. While Henri Lefebvre’s rhythmanalysis is perhaps familiar to many, rhythm has appeared in a wide repertoire of guises, in many disciplines over the decades and indeed the centuries. This introduction attends to the particular roles of rhythm in the formation of modernity ranging from the processes of industrialization and the proliferation of new media technologies to film and literary aesthetics as well as conceptualizations of human psychology, social behaviour and physiology. These are some of the historical antecedents to the contemporary understandings of rhythm within body studies to which most of the contributions to this issue are devoted. In this respect, the introduction outlines recent approaches to rhythm as vibration, a force of the virtual, and an intensive excess outside consciousness.

complex systems phenomena of critical slowing down, and flickering

Your questions made me think of meta-stability and Simondon... I don't know if if I'm off in left field but here are my two cents' worth... Gotta say though that f is not just any (differentiable) scalar function… it's a nice way at "inducing" continuity where the underlying may not have it..

Yes, right — in fact distribution theory : representing a function by convolving against approximations to the identity with a kernel that converges to the Dirac delta function is a well known and beautiful way to densely approximate any integrable function — a much vaster set of functions, which includes wildly non-differentiable and even discontinuous functions — by infinitely differentiable functions.

If the second time-derivative is going to zero, one would be approaching a steady state of no change, i.e. no new energy entering or leaving the system.

The second time-derivative of what, prices of Apple stock, immigrant flows through Ellis Island ?  That is only the case when we’re talking about position (potential energy mass * dx).   

If the second time-derivative is positive, why would that induce flickering? If the second derivative is positive at a point, are not you not only providing half the story? Wouldn’t you need to see how the change is changing over time rather than tending? 

Yes exactly, that’s why I speak of second time-derivative f’’: change is f’  and change of change is f’’.

If the potential is locally a quadratic with nonzero second derivative, then it looks like a parabola (in potential space).   The classic dynamic (solution) subject to that sort of potential (differential equation) is harmonic oscillation. 

For the thing to flicker, one would need discontinuities in the system or very tight oscillations to the changing system... tending-positive to infinity, finding another “plateau” of zero (or near zero) and then another tending-negative to infinity and repeat
This flickering effect feels like a cycling of meta-stability where contributing factors within the system impede the system from acquiring a one way or the other... or exit that meta-stable state... the correlation lengths would depend on the energy dynamics of the system, how rough the cycling is, i.e. how much energy is required to get out of the troughs of the meta-stability yet not enough to break away from the cycling and revert to the meta-stable trough. Experimentally, to break the spell one needs to introduce ever larger amounts of energy, heighten the amplitude of the energy dynamics as roughness into the cycling so one overwhelms the threshold boundary and break free from the prevalent dynamic onto another regime. You gotta introduce some rough stuff into the system, i.e. introduce difference or change, to mix it up and break free from the toxic stability....

Does this make sense?

Not clear what you mean by all this.  Are we speaking of the base space, or the state space of configurations, or the space of potential energy (functional on configurations)?

I hope this doesn’t land like a hair in the soup, like they say in Qc French.

hahaha , what’s that in quebecois?

Best, Felix

P.S. I found this reference on my way to somewhere else... thought it might be an interesting comment to the death scenario of the .
