In 1746 Johann Heinrich Pott obtained a "simple earth" (compounds which did not dissolve in water, melt in fire, or burn in air) from alumen. Following the practice of the day, he called it "alumina". By 1790 Lavoisier had established the present system of chemical nomencalture, which was becoming internationally accepted. In that system, metals had names ending in -um. Hence platinum, molybdenum, and tantalum. When Humphrey Davey believed he had isolated a metal from alumina, he called it "aluminum". However, due to the chance vagaries of language, many metals were prepared from compounds ending in "i", and became therefore ----ium. The momentum of the times carried aluminum with it. Until 1880 no element had an English name with more than four syllables, ex- cept aluminum in Britain. Even now, those that do are not common. Therefore, it is *aluminum*, NOT *aluminium*. ------------------------------------------------------------------------------- In the article, Asimov brushes off the French and German appelations (alumini- um) with the statement that they didn't speak standard English. Additionally, while not saying so, he implies, at least with the first reading, that Davey discovered aluminum. Those criticisms aside, Dr. Asimov makes a good case for "aluminum", one which we colonials find useful. As for the date, considering the expansiveness of the colonies and the diffi- culty of travel, could it be that the month was far more certain than the day, and was given precedence?

I don't believe *I* ever mentioned NASA. I was explaining why most "space resources" studies to date have had such a narrow focus. That's an important part of my point; this whole thread is about the difference between commercial planning and government central planning, and related differences in attitude and vision. I'm not doing it to "kick NASA down", and I don't believe that NASA is an "evil empire". Isn't it possible to making factual statements or reasonable observations about something anymore without being guilty of "bashing"? Furthermore, I never claimed you mentioned NASA. I mentioned NASA because it was important to my point. That's putting words in my mouth #1. >>Think tech constraints, not timeframes. .. >> > Hmm, I see. Let's see, I want to invest $100,000 in Szabo >Enterprises because I think I might see some good come out of it. That's putting words in my mouth #2. I have not solicited private investment funds for any of my proposals. I consider _exploratory_ business planning to be crucial for long-range planning for NASA. I have worked out explicit numbers for returns based on meeting tech constraints and various conservative trend assumptions (eg launch costs dropping by a factor of 2). The important aspect of such planning, like I said, is tech constraints not absolute schedule times ("Manned Mars Landing: 1980" -- from NASA plan c. 1970). In fact, I explicitly said that I would not consider large scale private investment likely until these tech constraints have been satisfactorily met. There's a role for NASA exploration and R&D if NASA is truly interested in space development and economic competitiveness. >Hell, if you said 10-50 years, I'd be happy. Most of my scenarios pay off IRR 20-40% over a 10-20 year period, assuming probable tech, discovery, and cost drop conditions are met (an inherently unpredictable proposition in the absolute timeframe, central planning pretensions notwithstanding). See my original post on this thread for more details. NASA has to give up pretensions of predicting the future and learn to live with the uncertainty just like everybody else in the R&D world. Ditto for space fans. > Once again you use my question as a place to get on your >high horse about centralized beaurcracy. I never mentioned it, and >I don't support it. Glad to hear it. I mention it because centralized bureaucracy dominates today's space program and the thinking of most people involved in it. It's quite relevant to the discussion, and I never claimed you support it. Words in my mouth #3. >>Fixed plans CAN be silly. But setting goals >>is not. Setting goals implies choosing some end points at the expense of others -- eliminating goals before they have been demonstrated to be unworthy. I explore scenarios, a wide variety of scenarios and try to find those which payoff the most soonest. A diverse set of goals can then be based on the most promising scenarios. > Ah, I see, respected climatologists say it's ok so >I should believe them. Sorry, I'd still like to see more data. So get on your library's computer and do a lit search for "ethane && ozone && Science" already. I never said you should believe them just based on what I said.

Words in my mouth #4. > So, when does your venture capital company start up? Again, you totally misconstrue the reason for using business style planning here. Whoever has the talent to implement when the tech constraints are met, that's who you invest in. Meanwhile, the business scenarios are for exploring which are the most productive future prospects for commercial space development for the lowest amount of NASA exploration and R&D (the tech constraints to be met). Finally, please stop accusing me of misediting and putting words in your mouth. That is a very common occurence on this kind of forum, quite difficult to avoid, especially given this subject matter. You've screwed up badly at least four times yourself, claiming I said things that I never came close to saying, but that you arrived at by hasty interpretation. I suggest you read my posts more deeply for meaning, and I will endeavor to do the same.

It is a "cloud" of objects in orbit about the star. This cloud is so dense that no radiant energy escapes to interstellar space. In Dyson's words, a civilization capable of constructing such a system to harness all the energy output by their sun would be called a "Phase II" civilization. I hope that this helps.

A number of people have given the dope on this already, but let me add that the idea you could light a liquid bipropellant rocket engine by, in essence, holding a match under the nozzle, is just *nuts*. One thing you absolutely must do in such an engine is to guarantee that the propellants ignite as soon as they mix, within milliseconds. To do otherwise is to fill your engine with a high explosive mixture which, when it finally does ignite, blows everything to hell.

Indeed, some of them didn't even have that: they basically just did what they were told, when they were told, and that was all. Nor was this restricted to the dawn of spaceflight; Pioneers 10 and 11, still in flight and in communication, work that way. (Ames would have liked to give them some autonomy, especially given the long speed-of-light lags in the outer solar system, but time, money, and mass did not permit.) Mind you, even such simpleminded probes typically do have one or two decisions made on-board, e.g. the decision to switch command receivers when nothing has been heard from Earth for a while. -- All work is one man's work. | Henry Spencer @ U of Toronto Zoology - Kipling | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: 3 Apr 1993 12:38:53 -0500 From: Pat Subject: Luddites in space Newsgroups: sci.space,talk.politics.space In article <1993Apr2.165052.174@mksol.dseg.ti.com> mccall@mksol.dseg.ti.com (fred j mccall 575-3539) writes: > >While a hunk of sheepskin certainly is no guarantee of competence, the >lack of one in a complex field is potentially an indicator of some >holes in the requisite underlying knowledge. > I'd say the only thing a sheepskin indicates is that you are willing to stay at one task for N Years, in pursuit of a goal.

OFtentimes the drive to teach oneself means not being blinded by Dogma to areas of new possibility. Given the evolutionary nature of CS, that may actuallyt be a benefit.

Oh God. Here I am. Sticking up for szabo again. Not that I agree with a lot of his stuff, but you are grossly over-simplifying his position. NASA employees, like other federal workers are prohibited under the Hatch act from engaging in Political campaigns on any level. They are also prohibited from taking remuneration from outside sources, although a recent appellate court ruling has confused things. I would say that being paid by an organization that lobbies for Space would be questionable. Now congress-critters are different matters. They are subject to the cruelest standard of all. the voter. We can vote them out and do often for highly ir-rational reasons. Federal workers like judges hold great tenure and thus are bound by different standards. Now as for engaging in PRish activities or responding to requests for infor mation is part of their charter to educate the public. I am sure Mary or one of the other NASA employees, Ron, Peter, can cite the exact agency guidelines on what is and isn't acceptable use of Government time or Equipment.

Leo Enright (BBC Ireland correspondent) seems convinced it was soemthing like the AURORA secret military craft, probably in trouble, crossing the country.

Never make any criticisms that might shine a negative light on anything, _never_ criticize. Only sell, sell. What a load of crap. This goes back to the accountability issue, BTW. Nobody is responsible for anything, because it's against this truly bizarre but convenient form of etiquette to criticize anything no matter how bad it is. If NASA squanders $50 billion to build a Shuttle that costs over an order of magnitude more per kg than originally promised, I dare not criticize it. If SSF goes from promised $8 billion to projected $100 billion or more, and back to the design board again, I dare not criticize it. Hell, I dare not even point out the facts of the matter, in which harsh critique is inherent. And never, ever try to compare these projects against alternative strategies for space development. Gosh, that might be embarassing, and we don't want to hurt anybody's feelings, do we? It might make somebody think, change somebody's mind, *shudder*!

Folks like Fred McCall thrive on flaming and putting down other people's ideas, even (especially?) if they have little understanding of them ("The One True Szabo Plan"); they don't know how to handle something positive or original.

The only recent one I can think of is a clear case of corruption, and had nothing to do with his disagreeing with any of my posts, in fact I was responding to a thread I was previously uninvolved in. If being ethical makes one "Lord God", we are in big trouble indeed. >blah blah blah obnoxious fool yack yack yack woof woof woof It's too bad that giving negative feedback, pointing out important but uncomfortable facts, and having a little fun in the process makes one an "obnoxious fool". It's too bad that one can post a bevy of original, diverse ideas and have them lumped together as a "One True Plan" -- without even one intelligent comment about the specific suggestions. I wonder if this attitude is common, is it any wonder that so many space projects are out of control? How can we fix something if we can't even point out where it's gone wrong? -- Nick Szabo szabo@techboook.com ------------------------------ End of Space Digest Volume 16 : Issue 416 ------------------------------
