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.

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. ^ Loren Petrich, the Master Blaster \ ^ / loren@sunlight.llnl.gov \ ^ / One may need to route through any of: \^/ <<<<<<<<+>>>>>>>> lll-lcc.llnl.gov /v\ lll-crg.llnl.gov / v \ star.stanford.edu / v \ v For example, use: loren%sunlight.llnl.gov@star.stanford.edu "Eliminate the ninnies and the twits!" -- Devo ------------------------------ Date: 8 Jun 90 17:06:29 GMT From: uvaarpa!murdoch!astsun.astro.Virginia.EDU!gl8f@mcnc.org (Greg Lindahl) Subject: Re: HAWAII/ROCKET very long - 61k In article <1050400021@cdp> jhanson@cdp.UUCP writes: >The reason for posting this message here is that there are many >scientists who are unaware of the enormous environmental >and social costs associated with their activities.

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. -- David R.

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!

Robert Jaquiss Internet: robertj@tekgen.bv.tek.com ------------------------------------------------------------------------ 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 Classical Record Catalog - Nimbus Information Systems, Ruckersville, VA Birds of America and Shakespeare on disc! - CMC Research, Inc., Portland OR (800) 262-7668 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! E. J.
