At Santa Barbara (CA), the moon sets at 12h49 TU. The penumbra starts at 10h16 TU -> Moon's height = 24 degrees at Santa Barbara (CA) The umbra starts at 11h15 TU -> Moon's height = 16 degrees at Santa Barbara (CA) The totality starts at 12h15 TU -> Moon's height = 6 degrees at Santa Barbara (CA) The maximum starts at 13h03 TU -> Moon's height = -1 degrees at Santa Barbara (CA) ---> The best place in all USA is Santa Barbara (CA) and his surroundings ! <--- ^^^^^^^ You're lucky to live here ! And the best place in all the world is New Caledonia (Maximum at zenith) --------------------------------------------------------------------------------- _______ _______ ________ | Firstname: Frank /______/| /______/\ /_______/| | Lastname : ROUSSEL / ______|/ / ____ \/| |__ __|/ | E-mail: rousself@univ-rennes1.fr / /| | |____| |/ | || | Telephone: + 33 99 83 26 10 | || | __ __/ | || | | |\______ | || \ \\ __| ||__ | Address: 175, rue Belle Epine \ \______/| | || \ \\ /__| |/_/| | CityStateZip: 35510 \_______|/ |_|/ \_\| |_______|/ | Cityname: CESSON SEVIGNE Centre de Ressources Informatiques | Country: FRANCE --------------------------------------------------------------------------------- ---------- Science without conscience is only soul's ruin (Rabelais) ------------ --------------------------------------------------------------------------------- - Signed: The responsible of ASTROGOF project at Rennes' University of France - - who contributes to the development of CRI-CICB Gopher's server (ASTRO images) - --------------------------------------------------------------------------------- ------------------------------ Date: 18 May 93 06:22:27 GMT From: Dave Michelson Subject: Life on Earth (or elsewhere : -) Newsgroups: sci.space I wrote: > Hasn't some of the early work on the Burgess shale been > discredited in recent years?

Well, I don't claim any particular expertise in this area, but an opposing view is taken by Jeffrey Levinton writing in the Nov 92 issue of Scientific American. ("The Big Bang of Animal Evolution", pp. 84-91). While Levinton agrees that "a Cambrian explosion in animal diversity did occur," he points out that many of the claims that were popularized by Gould in his book 'Wonderful Life' have been refuted in the past few years. Examples: Wiwaxia novel phylum --> relative of a modern scaleworm called a sea mouse Hallugenia novel phylum --> a velvet worm of the phylum Onchophora Levinton notes that "these stories point to serious problem with all arguments about evolution that rely on taxonomic classification" of fragmentary fossils. He goes on to state that he (and apparently others) believe that "Gould and some other paleontologists have exagerated the diversity in the Cambrian". The article is interesting reading and well worth a hunt through your pile of back issues of Sci Am. -- Dave Michelson -- davem@ee.ubc.ca -- University of British Columbia ------------------------------ Date: Tue, 18 May 93 07:06:46 GMT From: TMakinen@CRABAPPLE.SRV.CS.CMU.EDU Subject: Life on Earth (or elsewhere : -) Newsgroups: sci.space In article flb@flb.optiplan.fi ("F.Baube[tm]") writes: >From: Dave Michelson >> >> Hasn't some of the early work on the Burgess shale been >> discredited in recent years? > >Yes.

Now it is coming round the full circle - many of the 'examples of heretofore unknown geni' as described e.g. in "Wonderful Life" have been recognized to belong into existing taxa, although not necessarily the original ones. The young liberalists tried too hard to turn everything upside down.

The launcher country is defined as the nation that rules the land area on which the launch took place. If the launch was not from ground (air and sea launches) the nationality is determined by the nationality of the launch carriers (aeroplains or ships). Mind you, I'm not sure what is the position concerning Antractica..

The "1992 International Space Year" Compendium has been jointly produced by PBS E/SS and the Student Space Foundation with support from the National Science Teachers Association's Space, Science & Technology Division to assist educators in grades K-12 in their planning and celebration for the 1992 International Year of Space. It is also designed to help educators and students investigate and celebrate space exploration for many years to come. This comprehensive compendium lists hundreds of classroom resources, including videos, books, research reports, posters, computer software, space societies, teacher training workshops, music, and more! Parents may also find this useful in supporting budding scientists/astronomers. 135 pgs.

See above. Note that if various industrialists had not provided the Nazis with supplies, they may not have gone to war. It's sort of like with Iraq - why would you think a country supplying you with arms is going to decide to fight against you? But this is getting way off topic. >>Try living on a different *place* on Earth for a while.

There may be fuzzy lines (eg., infomercials, kids shows about a toy like G.I.Joe or My Little Pony), but this is unlikely to be a situation where whether or not something is "advertising" is controversial, given the promoter's statements. Maybe the line between "good" and "bad" is 'arbitrary' (it's irrelevant here), but there is no *a priori* reason why a principled distinction can't be drawn between commercial and non-commercial speech. > I've spoken with lots of people who have lived in places >where that judgement has gone disasterously wrong, and cost people >their lives. > >And I have _no_ desire to live in one of those countries. I want to >try to keep the US from being one of those countries. Badly. The FCC (like the CRTC in Canada) does it all the time. The allocation (and regulation) of the use of airwaves is a good parallel to this situation. Many municipalities have bylaws limiting the size and location of billboards, without leading to any disastrous consequence. Given a choice between NYC's glut of advertising, and Ottawa's more subdued (but still readily visible) billboards, I'll take Ottawa every time. Similarly, cigarette advertising is much more restricted in Canada than in the U.S.; we still have a constitutional right to free speech.

If you can increase the amount of time the thing will be visible by a factor of, say, five that greatly offsets the increase in launch costs. >What worries me most is the bad precedent it would set.

The 100th will be a while elephant. An orbiting inflated billboard has a smaller audience than you think, is expensive and offers very little actual data space. One frame of bad resolution without audio. The advertising value is in its novelty. What body (if any) would govern this type of access to LEO? There is no world body with the authority now. That doesn't mean one can't be created. However, to paraphrase an economist "governments don't behave rationally, so why bother trying to predict what they will do?" Since you brought up science fiction, try reading Asimov's "Buy Jupiter."
