"Anthropic cosmology" with Barton Paul Levenson.
I don't go for that. It makes it sound as if the appearance of a planet that
can sustain life, as we know it, is somehow an inevitable consequence of the
history of our Universe. What evidence is there of this inevitability?
Indeed. However, we have the features we observe. Please provide evidence
that our appearance is an inevitable consequence of the laws of our Universe.
This isn't science. It's belief. First you must demonstrate the existence of
a god who went to the trouble of creating a Universe, before you can argue
that it would be senseless to create a Universe where life has not, or
cannot, evolve in order to appreciate said god's creation.

Write your reply.

assistant: The observed speed of one speeding object as seen from the other is
w  =  (u + v) / (1 + uv)
So for u = v = 0.51, the top is 1.02, the bottom is 1.2601, and w = 1.02 /
1.2601 or approximately 0.8094596.
This is only for u and v in terms of the speed of light.  If you use the S.I.
or the English system, the equation is actually
w  =  (u + v) / (1 + [uv / c^2])
which is a bit more complicated.

     To be honest, my question has been, what relation does the anisotropy
have with the observed clumping?  Should we not see anisotropy in the same
direction as the current location of superclusters?  Now, I know that
published results are Fourier spectra, meaning only the frequency/amplitude
is real, not the position.  But there are other ways of analyzing the data
that will also result in (partial) positional information.  I am wondering
why this was never done.

     If ours is the only planet capable of sustaining life, then I would
really wonder.  Yet, over the last two years, planetary systems have been
detected in 30+ star systems.  Now, none of these planets are Earth-sized,
since the detection mechanism are too crude to detect planets smaller than
Jupiter at Earth-like distance from a star.  However, it is encouraging to
find that the existence of planets is itself commonplace.
     The only available evidence for this is from the Earth's geological
record.  The cratering record on the Moon shows that the inner Solar System
underwent heavy sustained asteroidal bombardment for about 800 million years
after the Solar System formed.  About 3.8 billion years ago, this heavy
bombardment period ceased.  Within 200 million years, fossils came into
existence on the Earth - an extremely short period of time on astronomical
scales.  The Urey-Miller experiment also showed that given conditions thought
appropriate to the early Earth, simple amino acids form naturally within a
week.  Both of these results seem to indicate life will form whereever the
conditions are appropriate.  Our next bit of convincing evidence would be to
find fossils on Mars, which had a similar environment to the Earth 3.8
billion years ago.  If such evidence is found, I would strongly support the
idea of life being an inevitible consequence of the properties of this
universe.

PHYSICS NEWS UPDATE
The American Institute of Physics Bulletin of Physics News
Number 362 March 12, 1998   by Phillip F. Schewe and Ben Stein
WATER ON MOON, ASTEROID NEAR EARTH.  The Lunar Prospector spacecraft has
detected the presence of water ice, at a level of about 1%, in the soil at
the Moon's two poles.  Perhaps brought to the Moon by passing comets, the
water ice lies in valleys away from the Sun's rays. Its density was inferred
from the number of neutrons flung up when cosmic rays strike the lunar
surface (NASA press conference, 5 March).  Meanwhile, several observers have
spotted an asteroid, named 1997 XF11, whose orbit might bring it to within
30,000 miles of our planet in the year 2028. Its diameter may be as big as
one mile, making it one of the largest asteroids expected to have passed
within a distance equal to the moon's orbit. (IAU press release, 11 March.)
P.S.  The last news item will be largely superceded by the time you get this!

 I think it depends what kind of stereo effect you are after. In the sun
 example quoted, I believe you are exaggerating the depth effect in
 order to make the sunspots stand out. You'd have to do the same for the
 moon, because it is so far away. But here you are after imaging something
 that has real height, although this is only a very small fraction of
 the distance you are viewing from -- or apparent distance when you take
 magnification into account. But even a 1000x magnification would still
 leave the apparent distance as 250 miles, and you are looking at height
 differences of a few miles at most. So I'd guess even a 1000 mile
 stereo base would not give you much depth -- but this is a guess.
 Basically, the greater the magnification the greater the separation has
 to be. At least that is the case when photographing nearby objects - with
 longer focal length lenses you need a larger stereo base to get a
 'natural' impression. But of course you are not after a natural
 impression but an exaggerated one. Sorry, I don't have the data to hand,
 though it is available in a book or paper on 3D cinematography by
 Spottiswoode. All you can go by is similar triangle theory...
 Good point, assuming you are showing it.
 Even more important is getting the magnification exactly the same! The
 framing can be adjusted to a certain extent when mounting the slides,
 and the eyes can pull things into position if there is a good strong
 outline to act as a reference.

 Now just a minute!
 If an object relative to us is going to exceed the s.of l.  and its mass
become imaginary/whatever, then how does it manage to get to the point of
exceeding the s. of l. without actually equalling it at some point, hence at
that point it would have infinite mass?

Will they all be reasonably close to each other as a group in the sky?  Sort
of.  All the planets will be within a ninety degree section of sky.

assistant: The first rule for beginners in Astronomy is *** DO NOT BUY A TELESCOPE ***
Somewhere in your area is an Astronomy club.  Most probably your
astronomy class at College has some info on it.  Ask.  At the Astro
club you will have the opportunity to observe through many 'scopes.
Shortly you will find that different 'scopes have different personalities
and here you will have the opportunity to find which one is best for you.
Don't rush it.
At the same time, you will have access to the application of your
classroom learning with people who know the heavens as others know
-perhaps- fishing etc.  Take advantage of it. Enjoy.

assistant: Congratulations and welcome to a great hobby that will provide
 you with new things to see, do, and understand for the remainder
 of your life!
 Sorry, I don't know any retailers to suggest to you since I live
 far from you ;-) However I will take a moment to point out to
 you that for all things "cheap" and "good" are mutually
 exclusive adjectives ;-) That is especially true for telescopes
 which are, by there nature, not as susceptible to the economies
 of scale of many other goods and whose market is very tiny
 indeed. There are many choices you can make to keep control of
 the cost of the hobby so it isn't a hopeless case to do it on a
 tight budget but it takes study, and good judgement and it helps
 a lot if you are handy with tools.
 However the first piece of advice I'd give is don't be in a rush
 to acquire a scope. They make the sky a very big and very
 confusing place for someone new to observing and they often have
 the effect of causing the early purchaser to swear off the
 hobby. Find a club and hang out with people who know more than
 you do and learn from them. Start by learning to find your way
 around the sky, understand the motions of the sky, etc. Once you
 can reliably locate the major constellations move on to
 binoculars (ideally mounted on a tripod). With a normal pair of
 7x50 or 10x50 binoculars and a suitable star chart for them you
 can find a large number of deep sky objects, study the Moon,
 watch the galilean satellites orbit Jupiter, and many other
 things. In a year or so you will have decided whether the hobby
 is for you, you will have learned to read star charts, and find
 your way around the sky, and you will likely (if you have joined
 a club and participated) have a very good idea of what scope is
 right as a first scope for you.
 In the meantime if you have questions lets hear them ;-) We'd
 love to help.
