Peter,
It is not as though I don't have some grasp, but as they say about car racing, "Ninety % of the cost goes into the last 10% of performance."
The problem isn't so much the physical dynamics, as it is the psychological dynamics. As Robert McEachern points out, there is a tremendous amount of knowledge on the part of the observer necessary to decode even the most basic equations and what also needs to be taken into account are the inherent intellectual biases built into this knowledge base as it has evolved over all of recored history, as well as unrecorded history.
Being in the sailing world, as well as the physics community, you understand how peoples minds and world views are very much a product of context and that often what are assumed to be universal knowledge are finely honed and hard earned understandings of particular facets of reality.
We are frames within frames, like all those wheels turning within each other.
Personally I grew up in a situation where the prep school education was far removed from my somewhat threadbare landed gentry farm life and so there was a need to study the process critically. We are all educated by the prior generation and build on what they give us, without really recognizing its composite and patchwork structure, before having devoted our lives to its influence.
For one thing, what could be more fundamental to even the concept of history, than narrative? Thus time as a set sequence of events.
And while the enlightenment might have begun the process of rejecting an anthropomorphic deity, as well as monarchy, it still hasn't escaped the influence of thinking a central ideal has to be objectively absolute, that there is one frame "to rule them all."
It is a function of how our minds operate, as top down ordering processes and this is reflective of one aspect of reality; That coming together of input to create particular frames, which then, like prior generations, form the basis for the next frame.
What it overlooks is that underlaying dynamic, where these frames are only nodes in a network with no central frame, only the parameters of equilibrium and infinity.
Our consciousness is constantly growing into the future, while our thoughts are contracting into the past.
So just as the detector fields dictate the spin passed on, our preceding generations set the field for us and we can't escape it, only try to take a broader look, using whatever other frames are at our disposal and let the next generation do what they will.
Regards,
John M
