Actually *bolide* is ultimately related to the Greek *bolis* (literally, a
thrown object), while *bolometer* is related to the Greek *bole* (literally,
light ray).  As it happens, however, the two Greek words _are_ related.

There's an even better book on the subject, called "The Amateur Radio
Astronomer's Handbook", and is written by Robert Sickels.  It contains
all sorts of information about constructing your own equipment, from
simple radiometers to systems that allow you to detect and record
pulsars.

There are also plans for a hand-built 12-foot diameter dish antenna 
(I even built one myself).

There is also an organization of radio astronomy amateurs, called
"Society of Amateur Radio Astronomers" (SARA), and it publishes a journal
monthly.

It also supports a library of technical data, as well as the sponsoring
of various activities.

I used to be a member, but let my membership lapse about a year ago.

If you're interested in details, look for an ad in the back of 
Sky and Telescope for "Bob's Electronic Service".  Contact them,
and ask for information about SARA.  

I would provide you with the information myself, but it is in my 
office, and I am not and won't be for some time to come.

BTW: Bob's Electronic Service is _THE_ amateur radio astronomer's
mail-order supply house for radio-telescopes and related hardware.

I'm not endorsing it, I'm simply stating the facts.

As there seems noone to respond, I have a question:  How would they do it?
The old idea:  Packing all the CFCs in the now unused strategic missiles
and sending them to Mars?  What time will it need?  What chemistry is involved?

No, not at all.  You would only have a slightly cooler Venus and the atmospheric
pressure would still be ~90 times too high.  There would also be virtually no
available hydrogen for water (you could crack CO2 into oxygen if you could find
an efficient method and had enough time and energy).

Wouldn't it be more sensible in the long run to curb unlimited growth
in population, moving to other planets just puts off the date of
overpopulation and increases the scale of the problem and increases the
rate of use of limited resources.

Look, if you had the enormous available energy to move Venus around then you
would probably do better to go to the asteroid belt and use their mass to 
build orbiting colonies. This is a much more efficient expenditure of energy.
Or since we're talking on this scale, just dismantle the moon since it has a
lower binding energy (compared to Venus) and construct O'Neill colonies around
the Earth or in solar orbit.  Still population control is still the best way
to go.

Organization: Iowa State University, Ames IA


     In our Solar System, the planet VENUS is the only planet which sizewise,
masswise and substancewise closely resembles our planet Earth.
     The main difference between Venus and Earth lies in their orbits around
the Sun.  For one thing, Venus stays around 67 million miles away from the
Sun, whereas Earth stays around 93 million miles away from the Sun.  As a
consequence of the corresponding greenhouse effects, Venus' average surface
temperature is around 900 degrees F, whereas Earth's is around 60 degrees F.  
Venus, being an extraordinarily hot planet is unsuitable for sustaining life
(as we know it).
     However, if we alter Venus' orbit and make it similar to the Earth's
orbit, then the gradual process of generating life sustaining ecology on 
Venus will evolve automatically.  As a result, a second Earth-like planet
will be created which, in due course, will be readily and easily populated
by the human species.
     The present-day tendencies of Space Scientists and Space Technology 
consist in keeping Venus or Mars in their existing orbits and trying to install
on them machinery which will produce life-sustaining conditions.  This approach
most likely will not yield the desired results.  Indeed, creating life-
sustaining ecology on the planets (like Venus or Mars) whose present cosmic 
parameters, to begin with do not allow the existence of life on them, seems
improbable and impractical.
     As mentioned above, a practical way for creating a life-sustaining ecology
say, on Venus, is to put Venus in an orbit similar to the Earth's orbit, to
begin with.  This is the way, the only way.  Philosophically:

In addition to the energy and angular momentum problem, another problem is
that two similar sized bodies on similar circular orbits make an UNSTABLE
system!  The Earth and Venus would rapidly change their distance to the Sun, 
unless the above unspecified large energy source is steadily correcting the 
Earth and Venus orbits.  This instability explains why the planets are on
sufficiently different nearly circular orbits; among all the possible ~circular
orbits, only the most stable survived.  In some way planetary systems result
from a natural selection of the most stable configurations.

I would echo that Kane's books is a fairly good one -- of course,
Kane taught my Particle class, so that could affect my
viewpoint.

With that book (and especially the early chapter on the Higgs
mechanism) behind you, the chapters on Phase Transitions,
Inflation, etc., in

are digestable.  I think this is the best overview
