Sure! It's fascinating stuff, but for some reason we hardly ever hear about
it.&nbsp; My College Physics text only contains one single sentence about
it!!&nbsp; But check these out:

<P>"FTL" particles creating shock waves of light - it may be old news but
it's nonetheless very amazing stuff.&nbsp; These shock waves, or "Cerenkov
Radiation", are also the primary means of detecting neutrinos in our atmosphere.&nbsp;
It's a very underappreciated effect, IMHO.

Hi Hex et al!

Conspiracies? How are 'psychic healing' and 'crop circles' remotely
related to conspiracies??

A simple question about Chladni waveplates and how to image them via a
computer program isn't remotely related to a conspiracy.. It was simply
a question about how it could be done in software.

Nor is the anecdote that I wrote up which appears to be an antitime
phenomenon and which I've not seen yet, but which specifically referred
to what I would consider major physical damage that was reversed by some
odd process and recorded on video in lieu of just taking the witness'
word for it. I presented it only because it correlated with phenomena
that I think an understandig of negative entropy and thus antitime could
produce.

But your baby and bathwater dismissal of both of these innocuous posts
tied in to some bizarre link to conspiracies just makes no sense
whatsoever. Gee, guy, get a grip and make some positive contributions.
