Comments: Sent using PMDF-822 V3.0, routing is done by TUDRVA

Hi there stargazers....

Here's the solution to the problem of the (until now)
missing matter in the universe. At long last, a logic,
yet subtle theory has emerged.....

The mising matter all exists of disappeared socks.....

Yes, you read right, disappeared socks....

How often has it not happened that you throw your
socks, along with all your other laundry, into the
washing machine, and then, after you've washed, the
other laundry is there, but some of the socks, often
even all, have gone. You can search the machine, take
it apart, do what you like, you'll never find your
socks again.

It is obvious that some, uptil now unknown, universal
law is working overtime here.

After careful research and many painstaking calculations,
we have been able to pin down the exact number of socks
in the universe. It turns out that the total mass of all
the socks is remarkably close to that of the missing mass.

So here we see that logic once again prevails over
superstition.

Have a nice day,
Nick

    Why are you people so worked up over that proposed spaceport
in Hawaii? Why does it bother you people so much?

    And if you want to check out environmental effects, there is
PLENTY of experience at other launch sites. Check out the Kennedy
Space Center or Vandenberg AFB or Kourou or (possibly) Tyuratam or
(just a faint possibility) Plesetsk. None of those environmental
horrors mentioned in this proposed Environmental Impact Statement have
come to pass.

    And some of them are ABSURD. Like getting worked up over
hydrochloric acid(HCl). It is dangerous when concentrated, but it
easily dilutes to harmlessness. And chlorine is an important component
of one common and important substance -- table salt (NaCl).

    I think that concerns about the environment are completely
legitimate, but that those who make a big issue out of the environment
should take on more worthy targets.

Most scientists that I know are very concerned about the enviornment.
Poorly researched articles such as yours do nothing but harm the
environmental movement.

When you consider the relative speeds of stars around here, the Voyager-Sun
speeds are not too great.  Those closest stellar approaches are mostly due
to the relative motion of those stars to the solar system.  So the
spacecraft orbits around the Milky Way will look pretty much like the Sun's
orbit.

But no one really knows what the Sun's orbit is like.  It has been presumed
to be fairly circular, but according to a recent article in Sky & Telescope,
some researchers think it is quite elliptical.  The illustration suggested
the ellipse is centered on the MW center, rather than having it as a focus.

Subject: Tides


    I've been thinking about the Earth's tides, and there's something
I can't figure out.

    The Sun has 27,000,000 times the Moon's mass (the Sun is 333,000
times more massive than the Earth, which has 81 times the Moon's mass).

    The Sun is 391 times more distant than the Moon (93,000,000 /
238,000).

    Therefore, the Sun's gravitational pull on the Earth is 177 times
that of the Moon (divide mass ration by square of distance ratio).

    This is what we would expect -- we revolve around the Sun every
year, not the Moon.  But it seems to me that tides caused by the Sun
should be 177 times stronger than those caused by the Moon!  What's wrong
with my reasoning?

    (advThanksance, and all that.)

Hello:

     I received the following newsltter and scanned it with an optical scanner.
If there are any errors I apologize.  If you want more information; please

Vol. 'i, "Issue 2    U.S. Geological Survey, Reston, Virginia
  May 1990

Greetings once again from JEDI central! This is the second
"JEdIgram" to bring you up-to-date on late-breaking developments on
the Joint Education Initiative. This is an effort by the U.S.
Geological Survey (USGS) in association with the National
Aeronautics and Space Administration (NASA), the National Oceanic
and Atmospheric Administration (NOAA), The Smithsonian Institution,
the American Chemical Society and other organizations to strengthen
the teaching of science in elementary and secondary schools by
sharing scientific data through the revolutionary storage medium
called CD-ROM.

The JEDI Teachers' Workshop, scheduled for July 9-27, is coming
along nicely, thanks to the outstanding efforts of Jim Sproull
(McLean High School , VA) and Mary Orzech (USGS). Twenty teachers
representing 9 states from across the country have been selected to
participate in the workshop. Donna Scholz, a senior scientist from
TGS Technology working out of the Eros Data Center, Sioux Falls,
South Dakota, will be conducting a 2-day tutorial on the basics of
digital data, remote sensing, image processing and geographic
information systems (GIS).

Industry participation in JEDI continues to grow. Thus far, we have
firm commitments from 6 different CD-ROM drive manufacturers for at
least 20 CD-ROM dri ves to be donated to schools of teachers
associated with JEdI. These manufacturers are as follows: Shinano
Kenshi Corporation (SKC), Hitachi Corporation, Laser Magnetic
Storage, Inc.(LMSI), NEC, SONY, and Toshiba.

We are hoping to make a major announcement very soon concerning the
donation of 20 complete CD-ROM computer systems. These systems will
include CD-ROM readers and will be used during the JEDI Workshop and
subsequently placed in the schools of the participating teachers.

Can you help with our JEDI Wish-List? We need contributions, large
or small, to help with incidental expenses that include: (1) housing
for seven out-of-town teachers; (2) text books for Remote Sensing
Applications graduate course; (3) transportation expenses for
teachers from California, Idaho, Ohio, South Dakota, and Wyoming;
(4) chartered bus for teacher's field trip to Charlottesville,
Virginia; and (5) other workshop expenses. If your organization can
help, please contact our industry liason, Dr. Roger Hutchinson, (CD
ROM Inc. , 303-231-9373).


There is quite a variety of educational CD-ROM discs already
available in the marketplace. We are tal.ing with the producers of
many of these titles and already have commitments for at least 20
copies of each of the following products:

Electronic Whole Earth Catalog - Broderbund Software, San Rafael,
CA (800) 5216263

World Fact Book - 1989 - Quanta Press, St. Paul, MN - (612)
641-0714

Ruckersville, VA

Birds of America and Shakespeare on disc! - CMC Research, Inc.,

I Speak English - 'Lntcl--hnica International inc., Midwest City,
OK (800) 5943663

Voyage to the Planets - Astronomical Research Network, Maplewood,
MN (612) 4885178


As we indicated last time, the CD-ROM discs which are now being
prepared will provide the JEDI Workshop participants with a rich
assortment of scientific databases and "visualization" software upon
which an innovative set of activity materials can be developed. Once
the activity materials have been developed, we plan to release a
limited number of preliminary JEDI packages to 25 to 50 "beta" sites
for initial shakedown during the August-September timeframe. The
beta sites will be supplied with CD-ROM drives donated by
participating drive manufacturers.

In addition to beta sites, we also envision an even larger number
(perhaps 200 or so ) of JEDI "evaluation" sites. These sites must
provide their own hardware (IBM or compatibles, 286 class or higher
class) but will receive the full set of JEDI discs and teaching
materials. If you would like to be a JEDI evaluation site, please
complete the form included with this JEdIgram and return it to Mary
Orzech at the indicated address.

Well. that's about it for this JEdIgram. We'll be back soon with
another update. Keep those cards and letters coming!
