Caustic Quilt

[David Dalton]

A physics clue came to me while I was semi-asleep.

It is "caustic quilt", so a mesh that is like quilt
stitching and is formed from caustics, or possibly
characteristic curves.

I just wanted to note it on these groups for the
record; perhaps someone else will make something
more of it before I do.

For those not familiar with caustics, one simple
example is the apple-like curve that can be seen
when light shines in on an angle into a cup of tea.

I will add it to past clues that may help me and
collaborators develop an interstellar drive.

We already have an interstellar drive, unfortunately for we short
lived species, it will take many lifetimes to get to Proxima Centauri,
let alone any of the less "proximate" suns.

You're a geophysicist. Astrophysics is out of your discipline however
deep time & cladistics is well within. When you understand our lack
of understanding of deep time, come back with some relevant dreams (if
dreams can ever be called relevant).

Perhaps we will find that, like energy levels of the hydrogen
atom, there are corresponding levels of the speed of light,
and so far we have accessed just the lowest level. This
may be related to branches of the inverse tangent function,
and entropy (S-Atan). :-)

Well, I have done introductory astrophysics and spent many
years in a Department of Geophysics and Astronomy, and
have studied some differential geometry and anisotropy,
but I do hope to work with collaborators. And note
that, as described on my web page, I got a peek into
higher dimensions during my sub stare.
