That's an interesting suggestion.  When everything seems impenetrable /
indecipherable, we're in a high entropy state.

Like when you first get off the airplane in some alien culture and so much
of what goes on seems an utter mystery.

We're more like newborns.

Then as we "learn the ropes" and start to "figure it out" there's a sense
of Entropy decreasing.  It all makes more sense.

To a point.  :-D

Is the self-education process itself a struggle against our own mental
entropy?

I really like how I can put LaTeX between dollar signs in a Jupyter
Notebook and use it inline.

I started on a Polyhedrons notebook.  This is where I've invested a lot of
time over the years.

Bob and Wayne on math-teach say my use of Quadray Coordinates is not math.
Some kind of hocus pocus.

I'm the only one in the world who seems to think they have a place, if only
to stimulate our thinking about coordinate systems more generally.

In the sense that we all start out ignorant of what these curricula aim to
signal, I think we all begin in a bath of noise.

Thanks as always for intriguing input.

I'm on a physics teacher list where they like to argue about Entropy and
how best to teach about it.

They're talking thermodynamics more than information theory, but that's all
the more reason to look for these unifying concepts.

Perhaps Hell is pure nonsense, separated from Heaven by the thinnest of
veils, like a decrypting key.

Like the less redundancy in a channel, the purer the signal, the closer it
comes to appearing random, if we're locked out of its meaning.

Right?
