Very strange.  The director of the Center for Meteorite Studies at
Arizona State U. loves to talk about how he can always tell if a
reported fall is a hoax because people who aren't describing a true
meteorite hit invariably describe the sample as "still hot" when they
found it, when in fact actual meteorites are usually very *cold*.  As
he described it, only the outermost layer heats up on entry to the
earth's atmosphere, and the rest of the rock is still the temperature
it was in space - cold.  So immediately after landing, the hot outer
layer gets cooled down from the cold inside, and the whole thing feels
cold when you pick it up.

  It probably depends on what frequency/wavelength you want to
investigate.  In the traditional shortwave region and even into the VHF
and UHF range antenna/system temperature isn't likely to be below 100
degrees and a you'll get diminishing return from lowering the
temperature (noise figure) of the radio equipment.  It also depends on
the performance of your antenna and what kind of sidelobe performance it
has.  If it is "looking" at terra firma to a significant degree you'll
have noise from that source as well and truly low noise equipment won't
return as much benefit.  Building low noise amplifiers into the
microwave region is an achievable goal but I think you might do well to
examine your system requirements before you begin such construction.

As many have mentioned, Venus is pretty easy to spot in daylight if you
know right where to look.  What about other objects?  A couple of
months ago I followed the Moon, Mars, and Aldebaran up the morning
sky.  After sunrise, I put my solar filter on my SPC-8 and watched the
Sun for a couple of hours.  Then, using the Moon as a "pointer", I'm
sure I saw Mars and Aldebaran!  I couldn't find them using binoculars
though, and that may have been a problem of a) focus, or b) hallucination.

Any thoughts?

This is a repost of 6 Oct. posting (revised)...

We at Langley Research Center received news on Thursday, October 2,
1992 that NASA intends to shutdown the following satellites in
December to save about $15M:

     NUMBUS-7

     ERBS

     NOAA-9 (partial?)

     NOAA-10 (partial?)

     UARS (SPRING 1993)

Some of the following experiments that will terminate when
their satellites are shutdown are:

     Stratospheric Aerosol Measurement II  (SAM II)

     Earth Radiation Budget Experiment (ERBS) (3)

     Stratospheric Aerosol and Gas Experiment II (SAGE II)
     
     Total Ozone Measurement System (TOMS)

     Halogen Occultation Experiment (HALOE)

     Microwave Limb Sounder (MLS)

No plans have been stated to restart the satellites.

Budget cuts are specified in House Conference Report 102-902
that is attached to HR 5679, Sept. 24, 1992.

 I am curious. When I lived in Chicago, I found that boric acid WAS the final 
solution for taking care of roaches.. Let's hear some tales. Here's one from me.

At Californial Polytechnic State University in San Luis Obispo, an experiment was performed
in the early 60's on some Cuban roaches which were supposed to be one of the largest in
existence. Apparently, some droppings were placed in a trash can, and now they
are underneath the science building. As of 1983, they were still there, at least a zillion
of them, scaring the crap
out of students who walk into the labs at night to work on a project, only to find them
dropping off of counters, etc. Fast critters, they were. At any rate, one Thanksgiving, 
a roach got stuck on some duct tape in the physics labs. Physicists being the curious
types, placed him in a mayonaisse jar, poked a few holes in the top, and left him...
over Christmas break. When they came back, Enrique (his adopted name) was still as
active as a hungry roach in mayonaisse jar, to coin a phrase. When they droppered some water
in the jar, Enrique ran over and immediately sucked up the entire amount. So they dropped
in a small chunk of peanut butter.... Same results... So they left a huge chunk in the jar,
along with plenty of water.. Went home for the day. Then next day.. Guess what????

Enrique had eaten until his stomach exploded.. Perhaps the solution to the roach
problem is to place open jars of peanut butter around the house. Sort of like a 
Roach Cafe........

over 100

Sounds apocryphal. Why? I heard the same story at the new mexico
school of mines. Common features: 1960's, "very large roaches", trash
can, subsequent infestation.

This must have actually happened somewhere...

I've never heard of PbO2 used in paint either ( PbO2 is black!!)
but it does exist quite happily at room temp and pressure.

If you don't believe me cut open your car battery
and look at all the black stuff on the positive plate.
Yes that is PbO2 and you will find it is stable at room
temp and pressure.  There are two main PbO2's, -
alpha and beta.  Although formed under rather extreme
electrochemical conditions, they can be formed chemically
(I am told) without too much trouble.

Two that are fairly easy to make crystals from are copper sulfate
(bright blue) and chrome alum (dark purple-almost black).  I think I
recall hearing that mixtures of chrome alum and ordinary alum make
prettier, lighter-colored crystals.

You might be able to get copper sulfate at bigger hardware stores.
Maybe chrome alum, too.

No.  Bleach (a dilute solution of sodium hypochlorite) is made by 
"dissolving" chlorine gas in a dilute solution of caustic (sodium hydroxide):

      Cl2 + 2 NaOH  ---->  NaCl + NaOCl + H20

Acidifying the solution with something like sulfuric acid shifts the 
equilibrium to the left by removing the sodium hydroxide:

      Cl2 + Na2SO4 + H2O  <----  NaCl + NaOCl + H2SO4

This is not unlike the dissolving carbon dioxide in caustic to form sodium 
carbonate or sodium bicarbonate.  Upon acidification, sodium carbonate and 
bicarbonate effervesce carbon dioxide.
