Hello -

I'm interested in finding some good references in Astrophysics and 
astrodynamics, so I'm wondering if there's a FAQ for this group 
available, or if anyone has any advice they'd like to offer me.

Basically, I need an introductory reference; calculus and formulas are 
what I'm interested in, but a glossary and examples are good too.  I'd 
just go to a local university and check out an intro text, but I'd 
prefer getting an "established" book if such a thing exists.

Thanks for any assistance

It's the divine spark of YHWH within us that urges us to take
literally His statement that the descendants of Abraham shall be
numbered as the stars in Heaven.

The only problem is the method:  to achieve the AstroZionist vision,
one must study Torah and Kabala.  Only after sufficient preparation will the
AstroZionist be ready to face the challenge, whether it be moving
Venus into another orbit, terraforming Mars, or traveling to the most
distant regions of the Universe at will.  The scientific method will
fail, and leave death and destruction in its wake.  Indeed, the 
AstroZionist vision will be fully realized at the moment of the next
Holocaust.  Those who fear YHWH will yet again be rounded up for
persecution and destruction.  They will depart in the blink of an
eye, and their altars to YHWH will be found and the Shema heard for thousands
and millions of years hence on every planet from here to the Andromeda 
Galaxy.

This statement is good, but it is better to say diffraction limited.
Actually, the saying should be something like: "1/4 wave_front_
accuracy _and_ diffraction limited (i.e. a transverse abberration of
less than one) within the same region of focus." (source: Suiter, Telescope
Making 32)  Yes, it is possible to
have a 1/12th wavefront mirror that isn't diffraction limited.

Amen to this!  The coma in a newtonian is normally _not_ seen in the
eyepiece.  It is more likely you are seeing astigmatism introduced
by the eyepiece if you see funny shaped stars toward the edge of the
field.  In this respect, the most recent FAQ on telescope buying is
wrong.  Coma isn't nearly the visual problem that most people think
it is.

     Thanks to everyone who responded to my original post.  This is a
     summary of the responses.

     The anomoulous TV reception I saw was not due to the aurora.  It was
     coincidental that there may have been auroral activity going on at the
     time.  I am told that auroral activity effects would not have been
     sufficient to maintain a usable TV picture.  The reflected bandwidth
     is too narrow.

     Instead what I experienced was Tropospheric Ducting, which can occur
     during a temperature inversion with dry air above moist air.  I'm told
     its common in late summer, and Lake Erie is a good source for moist
     air.

     As for the stations I picked out, the following identities have been
     proposed:

     9    CFTO-TV Toronto (CTV-network)
          (re-broadcast from Windsor on same channel?)
     31   City TV Toronto  (but apparently not listed in TV guide?)
          or Ann Arbor MI  (I thought I was picking up a Canadian Station
     38   ???
     40   CBC (re?-)broadcast from near London  (CBLFT2-TV?)
          or SRC [French] in London (or is this likely to be channel 38?)

Practical?  If we had control of the energy resources to move Venus's orbit, I

I have a Super Polaris mount with the Celestion SP-C80 refractor. It's
a good system, with a lot of flexibilty in mounting different scopes. There's
a camera mount that hangs on the counterbalance arm, too. Neat.
 
You can get adapters for the Genesis, which I note you're interested in,
and the Russian 6" Maksutov from INTES as well.
 
I've added the half-pier extension and I'm thinking about adding the one-axis
drive, mainly for visual tracking at high magnification for planetary and
lunar observing.
 
The only weak point in the Super Polaris is the tripod legs. They're far
better than the wooden legs on most imports, of course, and are made of
some unknown tropical hardwood, but I wouldn't mind having bigger ones for
more stability. I may make a set. Wobbles damp out pretty quickly as it
is, but I'd like something heavier still. The mount is heavy and bulky as
it is (particularly with the half-pier installed) so doubling the weight
of the legs wouldn't really make it any less convenient.
 
One other thought: I notice Meade now offers their line of SCTs on the
same heavy duty GEM mounts used for their new line of refractors. Certainly
worth looking into as well. They have tubular steel legs and two drive
options, including a computerized drive.

What do we know about the origin of the seven-day week?

My guess, somehow supported by informal readings, is that the lunar month
was divided into four weeks corresponding to 'the four lunar phases'.

I also read that 'seven' might have been suggested by the number of 'planets'
known (i.e. 5 planets + sun + moon).

On the other hand, I heard that the Egyptians adopted a 'solar' ten-days
'week' as early as the third millenium b.c.

Anybody out there who can provide more solid information?

The book goes on to describe several amazing feats pulled off by the use
of light on mammals, including the author's own arthritis going into 
remission once he started spending a significant amount of time outdoors
every day.  He talks of friends who have likewise felt better after going
through the same regimen.  All of this makes me a little skeptical.  Well,
more than a little skeptical.  The topper came when he claimed that the
type of light used in one woman's chinchilla farm helped determine the 
gender of the litters - even when the new lighting had been installed
1/3 to 1/2 of the way through the gestation period.  So now I'm highly
skeptical.

I hate to say this about any book, but I've given up on it and I've stopped
reading it.  I got bogged down in his puzzled accounts of his attempts to 
get the scientific community to look into his discoveries, and his repeated
rejections when he applied for grants.  Of course, during this time he 
constructed no actual experiments to show what he wanted to prove.  All of
his evidence is anecdotal.  The author strikes me as a tinkerer who doesn't
really care about all that stuff about scientific method.  He has no degree
in science (he was given an honorary B.S. by some college), and he didn't 
seem to be terribly interested in learning enough science to answer his
questions.  But still, there are questions.  There is mention later on of
things like electronics companies recalling TV sets and a Congressional
investigation that he calls "the case of the tired children".

So my question is this.   Is there any validity at all to this guy's
assertions about the effect of light on mammals or even plants?  Has any
work been done in this vein?  I'm interested in finding out, but I just 
can't read this book any longer.  This book doesn't tell me anything, and
I just get frustrated by this guy's attitude.
