I don't know the details, I don't remember them as being well defined. It goes something like this: When the pressure in the aveoli goes over a certain level, the hemoglobin absorbs O2. When it drops below a certain level, the hemoglobin gives up CO2. This is fuzzy knowledge, so corrections/clarifications/"you don't know what your talking about" are all apprciated.

Gee, I don't need a doctor to put on a Bandaid, decide when I'm sick, or any of those. Lambasting someone for talking medicine without knowing anything about it (no degree required -- just some knowledge, which you don't appear to have) is rather like, well, like lambasting someone for talking economics without knowing what they're talking about -- or talking anything else without knowing what they're talking about.

Most people think Newtonian physics; some think Einsteinian physics; the physicists, though, are out there doing stuff that 'just-plain-folks' would think is counter-intuitive, because the physicist is somewhere out in (or beyond) quantum mechanical physics. >Or do you mean, the way things work are how the gov decides, and, since >economists advise Congress, the IRS, the Prez, and anyone else who will >listen, how an economist thinks is how economies run?

Yes, and of course moving parts (with their moments of inertia) are great in a weightless environment. And lets not even talk about lubrication (and since you postulate a 'high plasma' environment, I assume you're just going to shove these chips unconnected out into a plasma field -- so what about lubricant properties in vacuum and the temperature cycles they would be exposed to?), repair, replacement, weights, etc. SEU isn't that major a problem, nor is your 'plasma environment'. If it was that big a problem, we'd still be using Echo satellites instead of all those birds with the solid-state widgetry in them. There are some ham satellites that use OFF THE SHELF electronics for things.

I mean, let's take a look at the sequence of events here that led to this flurry of assaults from little Tommy Mac, shall we? He wrote me some private notes all about how I shouldn't flame Nick just because he wants to call me things like 'Luddite'. I explained to him that as long as Nick elected to behave that way toward me, I would continue to behave that way back, since Mr Szabo is certianly not entitled to any special dispensation. My only other 'sin' toward young Tommy is to point out how shallow and unthought out his libertarian politics are. Suddenly there is a *flurry* of Tommy Mac notes. Yeah, sure sounds like I attacked you and provoked all this, doesn't it, Tommy? As for how old I am, older than you, I would suspect. But I don't call you "little boy" because of your age; I call you that because of your decided lack of maturity. Now, mine is nothing to brag on, but I've got a 4 year old niece who displays more maturity than you do. >>>Happy now Fred?

Wouldn't you agree, Fred? Right. Do what Tommy does and lie about who started this particular little string. No ego there, except that I wasn't inclined to take a private lecture from Mr Tommy about giving Nick 'The Lip' Szabo a special dispensation to be abusive because Tommy likes his politics. This, of course, naturally led to Tommy 'Want My Mommy' Mac going into public attack mode with his much-(self)vaunted lack of ego. >Yes, Fred, this is an ego-game now.

Well, of course not, Fred! I assume you know them, and were merely ignoring them, and I don't want to raise your ire by making reference to free-mark... oops, I mean 'libertopian' thinking.

Actually, it's just the opposite. Because it can change the rules whenever it pleases, it fails. "Market failure", broadly interpreted, means that situation where the market mechanism fails to meet the needs and desires of the people that make up and are served by the market. To get back to space, NASA, or at least, some parts of it, fails to meet the needs of the people for whom it was dedicated. SSF is a great example. NASA was entrusted to build a space station, with some abilites or another, for X dollars. Now, we have spent far more than intended, and don't have a space station, and will soon not even have that expensive design, since they are essentially starting over. If you don't think there is a government failure here, then you must be way too high to drive home safely.

Since economic value comes from the valuings of human beings, then morals, i.e. principles based on human valuings, are an integral part of economics. To ignore it is just so much simplistic, intentional ignorance of something you (apparently) don't like. Besides, as I said, the moral argument is supplemented by the utilitarian argument, WRT efficiency, best use of resources, land and labor, et. al.

The Start rocket is a conversion rocket. It is based on the Topol missile system's ballistic missile in service with the armed forces. [Shiryayev] This will be the first experiment to dispose of an SS- 25 strategic missile naturally, so to speak. In order to avoid having to blow it up--which is disadvantageous from an economic, environmental, and even commercial viewpoint--the strategic launch vehicle has been converted, and this hangar was built specifically for the launch. Tribute must be paid to the authors of this project, which will not only help to save many material resources but will also provide an opportunity to earn good money on launches like this one. Many companies in various countries of the world have expressed interest in placing advertisements aboard the carrier. There are also proposals to use the Start-1 launcher to place artificial earth satellites in orbit. Experimental 'Start' Rocket Launched Moscow ITAR-TASS World Service in Russian 1537 GMT 25 Mar 93 [By ITAR-TASS correspondent Veronika Romanenkova] Reported in FBIS-SOV-93-057 26 March 1993 [p. 61] Moscow, 25 March--Today, at 1615 hours, the launch of the "Start" experimental rocket carrying a space apparatus was carried out. The ITAR-TASS correspondent was told this at the press center of the Military-Space Forces. The mass of the space apparatus is 260 kg. The operating height of the orbit is 700 km. The "Start" rocket is a converted rocket. It has been created on the basis of the "RS-12M" ballistic missile that is in service (known in the West as SS-25). The new space complex has been created from extra- budget funds (taking part in financing the complex were the "IVK" joint- stock company, the "Kompleks" Scientific and Technical Center [NTTs], and the "Bauman" State Technical College in Moscow. Thanks to this, the producer of rockets of this class--the Votkinsk machine-building works in Udmurtia--was given the opportunity to apply its state-of-the-art output for peaceful purposes, too. Wide opportunities are opening up here inasmuch as the "Start" can put into orbit space apparatuses with a mass of up to one tonne, which it is inexpedient to do by means of other carrier-rockets being operated today. The space apparatus will be controlled by the Flight Control Center of apparatuses for scientific and national economy purposes, which is part of the Military-Space Forces. Orbit Parameters Given Moscow ITAR-TASS World Service in Russian 0925 GMT 26 Mar 93 Reported in FBIS-SOV-93-057 26 March 1993 [pp. 61-62] Moscow, 26 Mar (ITAR-TASS)--Today the Flight Control Center reported that on 25 March 1993 the first ever launch of a "Start-1" experimental satellite was carried out with the help of a "Start- 1" rocket carrier from Plesetsk cosmodrome. The "Start-1" rocket carrier was designed within the conversion framework on the basis of the RS-12M intercontinental ballistic missile, which is known abroad as the SS-25 missile. The modernization of this missile fully meets the conditions of the START II Russian-U.S. Treaty on the reduction of strategic offensive weapons. The "Start-1" satellite, which is a dummy of correct size and weight for flying-design trials of the carrier rocket, has been placed in orbit with the following parameters: --initial period of revolution--101 minutes; --apogee--966 km; --perigee--695 km; --orbital inclination--75.8 degrees ------------------------------ Date: Wed, 7 Apr 1993 15:01:28 GMT From: "John S. Neff" Subject: Vulcan Newsgroups: sci.space I think I forgot to say the L is the solar luminosity(in watts), that r is in meters and s is in MKS units. Sorry for the omission. A more practical form of the relation for the subsolar temperature is to use r in astronomical units and the solar constant in watt/m^2. T(in K) = 392*(1 - A)^(1/4)/r^(1/2) where A is the Bond albedo and r is the heliocentric distance in AU. ------------------------------ Date: Wed, 7 Apr 93 17:28:06 EST From: MAILRP%ESA.BITNET@vm.gmd.de Press Release Nr.17-93 Paris, 7 April 1993 First European Space Debris Conference ends today At the initiative of the European Space Agency (ESA), the First European Space Debris Conference was held in Darmstadt, Germany, from 5 to 7 April 1993 gathering together 251 world experts from 17 countries including China, India, Japan, Russia and the USA. The main conclusions of the conference are: - Ground based observations with radar and optical facilities reveal the existence of about 7000 objects in space, which do not represent an immediate danger. However, adequate actions have to be taken in order to keep the debris hazard for manned and unmanned missions within safe limits. Of most concern are the long-term prospects of the debris hazard, particularly in those regions in space which are most heavily used, e.g. low Earth (900- 1500 km) and the geostationary orbits (about 36.000 km). - Clean up of debris is neither technically practical nor economically feasible. The thrust of the action must be towards preventing the creation of debris. Several preventive measures have been identified and implemented in space activities, such as releasing residual propellant in rocket upper stages to preclude a subsequent explosion generating many fragments, and the reorbiting at higher altitudes of geostationary satellites at the end of their mission in order to avoid collision with operational satellites. Further possibilities include destructive re-entry into the atmosphere to burn up the spacecraft or selection of orbital parameters to limit the lifetime. - The space debris problem can only effectively be solved by international cooperation. Bilateral discussions between space agencies on the debris issue have taken place since 1987. Furthermore, on the occasion of this First European Space Debris Conference, the first multilateral discussions among representatives of NASA, the Russian Space Agency, Japan and ESA took place in Darmstadt (on 2-3 April) to present results of their research activities, to identify possibilities for cooperation and to discuss methods for debris reduction. In view of the high interest this ESA initiative has stimulated, it is envisaged to hold a second conference on the debris issue in about 2-3 years from now.  ------------------------------ End of Space Digest Volume 16 : Issue 432 ------------------------------
