User:Juuitchan wants to know the difference between
straw and
hay; in particular, how to tell them apart.
Ship buffs: I wanted to know the power rating of a nice, powerful nuclear power plant, presumably from an aircraft carrier, and perhaps one from a submarine too, to add as an example for orders of magnitude (power), but I've been through pretty nearly all the U.S. aircraft carrier pages, checked the ships' own websites when they had external links, and haven't come up with a thing other than "two A4W reactors". Is the information classified or something? I wouldn't have thought so. If not, does one of you have a power rating of at least one aircraft carrier/submarine in any of your references? -- John Owens 21:06 22 May 2003 (UTC)
Hey Library Reference Desk! I have a HISTORY reference question: where might I find detailed county-by-county results for past U.S. Presidential elections? My specific question is New Jersey Counties in the 1860 Lincoln/Douglas contest, but I'm sure I will have other uses for the answer to the originla question. I'll even make an article on it, if I can find out where to get the info. Many thanks in advance... ArloBee 20:12 25 May 2003 (UTC)
Dubin, Michael J. United States presidential elections, 1788-1860 : the official results by county and state / Michael J. Dubin. Jefferson, N.C. : McFarland & Co., c2002. xxv, 225 p. : maps ; 29 cm. CALL NUMBER: JK524 .D778 2002 Alc The U of Penn library has it and I will go up there tomorrow for that (1 hour away). But if there turns outto be an online source somewhere, that would be pretty great. I guess I can copy some measure of facts out of that book without violating copyright? But I'll feel safer if there is a neighboring book of greater vintage that I can mine from for wiki. ArloBee 20:49 25 May 2003 (UTC)
In an aqueous solution of, say, a lead compound, why don't all the lead ions sink to the bottom? I suppose that lead is only denser than water because the atoms in solid or liquid lead are packed tighter than the molecules in water, but to me it seems unlikely that all the ions and molecules in a solution have exactly the same density. What is it that keeps them all afloat? -- Heron
I see. Thanks. So the 'ion/water thingamajing' has the same density as water. -- Heron 21:03 10 Jun 2003 (UTC)
Heron originally asked "why don't all the lead ions sink to the bottom". Off the top of my head, I would say diffusion. Random thermal motion of the lead particles tends to make them evenly mixed throughout the sample, and swamps the gravitational effect. It's the same reason the air in a room doesn't settle to the floor, leaving vacuum at the top. If the lead ions were much, much heavier, they would sink towards the bottom. The bottom would become positively charged, eventually repelling additional lead ions. -- Tim Starling 08:05 11 Jun 2003 (UTC)
as heard on US tv shows, what are "cooties"?
The circular saw is persistently listed on timeline of inventions as being invented by Samuel Miller. And yet I have a distinct memory of reading that it was invented by someone of the female persuasion, in some religious utopian community or other. Can't find my source, and it is driving me crazy. -- Cimon Avaro on a pogo stick 17:52 23 Jun 2003 (UTC)
Hi im a little confused on what this page is for, can i ask any guestion or only guestions regarding world events and or common knowledge. JS
