Sci.Physics is an unmoderated newsgroup dedicated to the discussion
of physics, news from the physics community, and physics-related social
issues. People from a wide variety of non-physics backgrounds, as well
as students and experts in all areas of physics participate in the ongoing
discussions on sci.physics. Professors, industrial scientists, graduate
students, etc., are all on hand to bring physics expertise to bear on
almost any question. But the only requirement for participation is
interest in physics, so feel free to post -- but before you do, please do
the following:

This Frequently Asked Questions List is posted monthly, at or near
the first of the month, to the Usenet newsgroup sci.physics in an attempt
to provide good answers to frequently asked questions and other reference
material which is worth preserving. If you have corrections or answers to
other frequently asked questions that you would like included in this
posting, send E-mail to sichase@csa2.lbl.gov (Scott I. Chase).

weird stuff

This is the sci.skeptic FAQ. It is intended to provide a factual base
for most of the commonly discussed topics on sci.skeptic.
Unfortunately I don't have much time to do this in, and anyway a FAQ
should be the Distilled Wisdom of the Net rather than just My Arrogant
Opinion, so I invite submissions and let all the net experts out there
fill in the details. Submissions from any point of view and on any
sci.skeptic topic are welcomed, but please keep them short and to the
point. The ideal submission is a short summary with one or two
references to other literature. I have added comments in square
brackets where I think more information is particularly needed, but
don't let that stop you sending something else.
