Brody " Subject: Calendar and Zodiak Newsgroups: sci.space I was just reading that the Earth precesses at a period of 26000 yrs. This means that over the past 2000 years, we have precessed about 30 degrees or one month. If the vernal equinox was in March back then, how do we account for the missing (or extra) month in our calendar? To reiterate, the vernal equinox is occurring 2000/26000 sooner than when it occurred 2000 years ago in a solar system coordinate system. In another 2000 years, will spring star in February, or do we account for precession somehow in the calendar? ------------------------------ Date: Mon, 27 Jul 92 20:32:41 GMT From: Dave Jones Subject: Calendar and Zodiak Newsgroups: sci.space In article <1992Jul27.183247.14412@eos.arc.nasa.gov> brody@eos.arc.nasa.gov (Adam R.

I just looked in my desktop database (actually the paperback 1991 Information Please Almanac, 10Mb equiv, $7.95 cheap) and on the subject of calendars it deals only with drift due to the solar year not being a whole number of solar days, and the various systems for correcting for that, adding days under various rules. This being the case, I will stick my neck out and say that the length of the solar day must be governed by three things: the Earths rotation period, its orbital speed (which causes a shift of the Sun's apparent position in the sky) and the rate of precession of the rotation axis. Thus a calendar based on the solar day must automatically be corrected for precession. I'll stick it out even further and assert that the sidereal day (which is not affected by the orbital speed) also incorporates precession. P.S. Don't make those nooses too small: I've a size 17 neck. -- ||))) If you build it )))))))))))))))))))))))))))))| ||))) They will cancel it - Field of Dweebs. )))))))))))))))))))))))))))))| ||))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))))| ||Dave Jones (dj@ekcolor.ssd.kodak.com) | Eastman Kodak Co.

The yearly calendar until @1950 was defined as the time between extremal positions of the sun: furthest north or south of the year etc. However, the position of sun with respect to the stars at the extremal point moves slightly each year- about the diameter of the moon per 36 years. The vernal equinox (spring) now occurs when the Sun is in the constellation Aquarius. During the Roman Empire the sun was one constallation over in Pisces during the equinox. After 1950 the length of the year is defined in terms of vibrations of cesium atoms which are ten million times more stable than the length of a year. ------------------------------ Date: 28 Jul 92 00:19:03 GMT From: Steinn Sigurdsson Subject: Calendar and Zodiak Newsgroups: sci.space In article <1992Jul27.220716.11396@unocal.com> stgprao@xing.unocal.com (Richard Ottolini) writes: The vernal equinox (spring) now occurs when the Sun is in the constellation Aquarius.

Radio transmissions started in the early part of this century. So we've had radio waves going everywhere and, especially into outer space at lightspeed for at least seventy years. Indeed, I see it that in a sphere of seventy lightyears radius, any intelligent life form either isn't advanced enough or won't receive radio. Or they don't want to speak to us. Or our early radio messages just got to them and they're just broadcasting back. Even so, leaving 5 years for time to think up of a message, we should have received messages from stars within a 30 lightyear radius. If extraterrestrial intelligence exists, then they must not be very popular with God, although some say that intelligence will almost certainly be developed by some lifeforms, who will use their sentience as their defense and weapon, so it is inevitable that a planet that can support life will soon have an intelligent species.

That is, I am looking for function that returns the time of year, given the position of the sun in geocentric ecliptic coordinates and a year of interest (e.g., 1994). This function only need be accurate to 1' from 1994 - 2000. Yes, yes, I know that I can use a true solar ephemeris (e.g., Van Flandern and Pulkkinen's formulae) to iteratively solve for the time of year, but I'd rather not take the time to write and test the code if an inverse ephemeris exists.

Please get this up on Compu$erve, and Prodigy, and any and all BBSs or systems! Memorandum Friday, July 24th, 1992 1. The House Appropriations Committee ("HAC") and its Defense Subcommittee Chair, Representative John Murtha, will take the position in conference with the Senate on the FY '93 Defense Appropriations Bill (H.R. 5504) that SSRT funding should be restored (said conference occurring probably sometime in early September). Nevertheless, the prejudicial language terminating SSRT contained in the HAC's Committee Report H. Rpt. 102-627 has passed into the outside world, and the same arguments against SSRT as are presented and justified in H. Rpt. 102-627 are butrussed by their presence in that report. 2. We must assure that there is as much positive support from Congress for SSRT as is possible before the HAC/SAC ("Senate Appropriations Committee") conference on the Defense Appropriations Bill. This will help to neutralize the "bad" language of H. Rpt. 102-627. 3. The Defense Subcommittee of the SAC will mark up its bill and its associated report in the next few weeks (I will see that specific data on this meeting, such as date and time, is posted as soon as I can get it). 4. Letters, phone calls, faxes, etc., should be made to the Senators listed following as soon as is possible; they are the members of the SAC Defense Sub. Ask that the SSRT DC-X ATD program be supported in the SAC's Committee Report on their Defense Appropriations Bill (which will probably be the _Senate's_ version of the House's bill H.R. 5504; their Committee Report _will_ sport a different number designator than that on H. Rpt. 102-627). The more and varied the positive contacts supporting SSRT these Senators receive, the better. All of the Senators listed below are members, of course, of the full Senate Appropriations Committee; in fact, the Chair of the Full SAC, Senator Byrd (D-WV) is a member of the Defense Subcommittee. The Ranking Republican of the full SAC, however, is _NOT_ on the Defense Sub. I've listed him below anyway. You should write/call/fax him too (Mark Hatfield).

People in the sciences are just beginning to pay real attention to the asteroid collision problem. Outside the few who are scientifically literate, almost no attention is paid to asteroid collisions with Earth. Next time you're with nontechnical types (at a party say) tell them the biggest environmental threat they face isn't some produced by humans but is asteroids and then watch reactions. If they are doubtful, inform them about Tunguska. A small part of comet exploded in Siberia in 1908. The resulting 10 MT blast leveled trees for 50 miles around and knocked horses to the ground 400 miles away. In 1972 a small (100m) asteroid almost hit the US northwest. If it had, we would have a major (multibillion) program designed to protect us. It missed (barely -- it went through the upper atmosphere).

I stress _may_. This thread has yet to lose that misanthropic assumption that so many eco-pagans hold: Man is not-life (or of the Earth - or of the whatever system that contains life). This is the result of the idea that man-made equal unnatural. But of course, our artifacts are as natural as termite- mounds and beaver dams. Otherwise, they would not exist in nature (here). We have as much right (power) to evolve as any other life-form. Attempts to disprove such will always degenerate into the man = non-life argument, which, of course, is wrong. Consider: Our presence -may- help evolution along. This value-judgement can never be resolved! Who will decide? Only something not-living can decide, since it won't be part of the process, but non-living things can't judge! Computers? How can they not be a part of evolution, being an artifact (tool) of an evolving life-form? Consider this: We get to mars, and find some bacteria that Viking missed, and discover it kills plant and animal life. Is it okay to kill it? What about small-pox? Polio? AIDS..... Or, if you prefer...is it okay to breed cattle and corn, irrevocobaly changing thier evolution for all eternity? And ours? It think the only tenable position has to be based on the question: Will this action be good for us? The eco-pagans would do well to learn this question... -Tommy Mac .

In the late 60s there were conferences - Wheeler and de Witt edited the proceedings for one, as I recall - on general relativity, the equation of state for neutron stars, there being no stable state for them above a certain mass. The name 'black hole' dates from then. Smith's negaspheres would have come from the Dirac Sea idea. Dirac's equation allows negative-energy states for electrons; but then why don't all the electrons fall into them? Ans: they are all filled, and the Exclusion Principle prevents it. A hole in the sea is a positron. Negative-energy electrons on the loose were never predicted.

(So far, only Alfred Hitchcock has seen the untapped potential of our feathered friends... ;) BTW, why would "podding" lead to counting? One advantage of the ancients is that they had recourse to being able to draw/write down their thoughts on these weighty matters. To be able to pursue such pastimes in one's head (be you whale or human) is quite a feat, and still more so to pass it to other generations. Whales do not have writing materials. Or at least not that we've observed. I think this explains why beaching occurs. They are wanting to make geometric drawings in the beach sand. To test this assumption, the ground around the next beached whale must be carefully observed. Usually gawkers and passers by have trampled the surrounding sand, obliterating their scribbles. This must be prevented. A helicopter flyby would be nice to take in the whole area around the whale... Richard Travsky "So long, and thanks for all the fish!"

I don't think that "chairs allow people to push them around" is the main proof that chairs lack intelligence. Other evidence, such as lack of anything that might support intelligence (neurons, electronic switching elements, etc) is stronger evidence. No, for practical purposes it is not proven that whales are not intelligent. They don't display human-like intelligence, but judging whales by lack of display of human thought patterns does not constitute significant proof of non-intelligence. By that proof, certain religious people, people who engage in extremely dangerous activities despite the risk, people with mental disorders, and even teenagers who commit suicide because a boyfriend/girlfriend left them would by your (and Russell's) definition be non-intelligent. -- Nick_Janow@mindlink.bc.ca ------------------------------ End of Space Digest Volume 15 : Issue 043 ------------------------------
