However, I would like to point out that you've been mislead about Einstein. In fact, it's quite remarkable how quickly the special and general theories of relativity were accepted. The original paper on relativity was published in 1905. By 1909, several other prominent researchers (including Hilbert and Minkowski) were working on it, and in the same year Einstein was awarded an honorary doctorate from the University of Geneva, and gave an invited paper at a conference in Salzburg. He was also appointed to a position at the University of Zurich. He was hardly being "looked down upon". [Source: "Einstein: The Life and Times", Ronald W. Clark] (I think physicists in general have displayed a remarkable willingness to quickly accept radical new theories, such as quantum mechanics and relativity, that seem to be full of crazy ideas, *as long as there is good reason to*. Alas, there seems to be no good evidence for "reactionless drives", and moreover many good reasons to suspect that such things are impossible.) -- Eric R.

Its distance from the Sun is 162 million miles. Speed in orbit is 48,347 mph; round-trip communication time is nearly 15 minutes. The spacecraft health and performance continue to be excellent, except for the partly deployed high-gain antenna. Galileo's engineering telemetry data rate has been reduced to 10 bits per second (through the low-gain antenna) to permit communication with the 34-meter ground stations. The spacecraft is in the dual-spin mode, with the upper part spinning at about 3.15 revolutions per minute and the lower part not spinning. Meanwhile back on Earth, the Galileo flight team has been very busy designing and reviewing the next trajectory correction maneuver planned for July 2, the next cruise sequence or computer program to control spacecraft operations starting in September, and the Gaspra asteroid encounter, scheduled for October 29. The team continues intensive analysis and testing aimed ultimately at deploying the high-gain antenna. ##### ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@kelvin.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |__ M/S 301-355 | "Imagination is more /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | important than knowledge" |_____|/ |_|/ |_____|/ | Albert Einstein ------------------------------ Date: 24 Jun 91 03:25:19 GMT From: cis.ohio-state.edu!zaphod.mps.ohio-state.edu!sdd.hp.com!spool.mu.edu!munnari.oz.au!manuel!ijcai@ucbvax.Berkeley.EDU (IJCAI Mail Box) Subject: IJCAI Early registration ********************************************************************* * 12th INTERNATIONAL JOINT CONFERENCE ON ARTIFICIAL INTELLIGENCE * * * * 24 - 30 August, 1991 * * * * * Darling Harbour * Sydney * Australia * * * * * * * IJCAI-91 * * ======== * * * * --------- E A R L Y R E G I S T R A T I O N --------- * * * * 3 0 J U N E * * * ********************************************************************* IJCAI-91 will be held at Darling Harbour, Sydney, Australia, 24-30 August, 1991.

I was looking due south out of my apartment here in Iowa City, and noticed a series of 'cloud bursts', which started at about 2h0m UT. It looks like they are about at 15h18m, -2deg15m. They are pretty bright, white/gray in color, and emit from a constant position. They expand/disperse in ~2min, with new clouds starting ~4 min. We have a pretty heavy cloud cover right now, so I really don't think that these things are atmospheric tests, but just on a whim, are there any satellite chemical releases going on at the moment? Thanks, Paul ------------------------------ End of SPACE Digest V13 #787 *******************
