  1. No, it has not. Watt invented the term 'horsepower' in 1782, but the term 'watt' wasn't adopted as a unit of power until 100 years later. Arguably 746 watts may have always been 1 horsepower, but not the other way 'round.

  3. Shape is important as well as material in reflecting microwaves. Many parabolic microwave antennas are fiberglass for example.
  4. Because you are used to hearing your voice as it is delivered to your eardrums through vibrations of your jaw, skull, and other tissues. The more you listen to recordings of your voice the more likely you will recognize recordings of your voice.
  5. Identify and destroy invasive species and/or replace/replant with native species. :idea:
  6. The mechanism is called a torsion pendulum. It consumes/transforms energy; it is not a 'source' of energy. Some clocks use the mechanism as an escapement, but their source of energy/power is a separate wound torsion spring. Torsion Pendulum Clock >> http://en.wikipedia.org/wiki/Torsion_pendulum_clock Torsion Spring >> http://en.wikipedia.org/wiki/Torsion_spring (Sorry the equations don't paste up correctly. Check the link to see them in proper markup.) hope this is ok
  7. Just to be clear, microwaving adds no 'radiation' to anything if by that you mean 'radioactivity'.
  8. We can thank the quacks and con artists who sell 'water energizers' for the concept of 'dead' water. They love no one more than those ill and vulnerable. Here's a listing of dozens of such pseudoscientific bamboozles. Dead Water, Lies or Fiction? >> http://liesorfiction.blogspot.com/
  9. A sticky wicket to be sure. Have the reserve people made any official appeal for exemptions? Have they brought the matter to the attention of the general public, or did you learn of it through casual conversation(s)? Also wondering if you have the Stonecrop in your own yard or have seen it elsewhere in the community? The solution here I think would be educating the weed warriors. Since any plant or community of plants can only occupy a finite area it seems to me pulling an invader out is worth the risk of leaving some to regrow. At the very least it gives a native an oportunity to occupy the space before any regrowth of the invader. In that vein I think an important adjunct to invasive removal is replacing it with natives whenever possible. I can accept that to some degree, but I don't see it as removing we peoples from responsible stewardship. One might argue we have 'naturally' evolved to pollute but that doesn't negate that we also naturally know better than to put the outhouse next to the well. The invasive plants can and do endanger native plants and so decrease biodiversity. A more immediate economic cost for some areas relates to eco-tourism inasmuch that if a unique plant or plant community is quashed, people will no longer travel to the area to see it. A particular concern to me in my own area is the English Ivy. It escapes into forests & climbs the trees where it adds 1000's of pounds to the tree, ups the wind-load by increasing surface area, covers over the trunk making it unavailable for birds, lichens and other native life, as well as going to seed. State laws exist to restrict it, but they and the counties often have no resources to combat it on public land let alone enforce the laws requiring private landowners to control it. Good stuff StringJunky; thanks for the input.
  10. For all the public commotion over genetically modified plants, invasive plants seem of little public interest. Granted GM plants have the potential to wreak havoc with agriculture and ecosystems, but invasive plants have already been at it for years. Where's the anger? The suspicion? The hue and the cry? Do you know what is and is not invasive where you live? Do you or do you not do anything about it? Do you think it's a non-problem? If you think it's a problem is it the other person's? The goverments' problem(s)? Who should do what, when, where, and for how much expense to thwart the invasive plant onslaught? I never paid much attention until I got on a jag hiking around looking for native plants, and even now I don't go out of my way to combat invasives. I mean I hack their insolent stemage & rip out their filthy little roots when I find them but I haven't joined or invested in any group kills. Here's a US government invasive organism clearing house site for your enjoyment. http://www.invasivespeciesinfo.gov/index.shtml While there are invasive creatures o'plenty, I suspect advocating that we'd better kill a bunch of plants will stir up less angst than say, erhm ... European sparrow hunting.
  11. Not sure what 'something' you meant, but forcing gun owners to have insurance might pit the insurance lobby against the gun lobby. Greed vs. greed. You can have my steering wheel when you pry it from my cold dead hands. Works for me.
  12. As farmers switch to growing new varieties they stop growing old varieties and so they stop collecting seeds of old varieties and so there is no seed stock for the old varieties. Without the old varieties (often called 'heirloom' varieties) there is a potential loss to get back to the original plants and so what was valuable about them to begin with. Part of that value is the food aspect, part the genetic qualities that 'naturally' evolved.
  13. No religion is a religion of peace. For every 2 people brought together under a religion, thousands are set apart. My imaginary friend(s) can beat up your imaginary friend(s).
  14. OK Quote works with toggle down. Switching back after quote I can bold and italic. Yep; can work around the rest I think. Thanks.
  15. Trying toggle...Trying toggle Voila! Pasting works from copy. Trying a link...http://en.wikipedia.org/wiki/Chain Well, that pasted but will check after Post-ing to see if it displays as a link. I see with the toggle down I lose all editor functions such as emoticons and inserting images though. That's not good. Will check if I can quote. As to browser I have IE. Since it works everywhere else this must be a problem specific to this forum. I have no plans to add another browser. If the admins can't fix the problem so be it. I'll make do without the quotes and type out whatever I have to.
  16. I am having the same problem as coden3 asked about a few posts back. I know how to cut/copy and paste thank you very much. When I paste to a reply box, nothing appears. The copied material is on my clipboard as I checked it using Clipboard Viewer. Neither does the quote function work for me. I don't have the problem in other applications. Little help?
  17. Pseudoscience is the appropriate category for learning about perpetual motion machines. Alternative energy is the appropriate category for learning about alternative energy machines and systems.
  18. Just took delivery of Ethnobotany of Western Washington: The Knowledge and Use of Indigenous Plants By Native Americans by Erna Gunther. I have been referring to an online source at University of Michigan for individual plants, but this is my first book. Looking forward to meeting old friends and making new. Did you know (according to the Michigan source) that chewing my native Fringecup - Tellima grandiflora will keep you from having dreams of having sex with dead people? Will see if Erna confirms that. :read:
  19. When relatively near the Sun, comets have 2 tails. The tail illustrated above -always directed away from the Sun- is the ion tail and is composed mostly of gasses. The other tail which is not illustrated is a dust particle tail and trails more or less behind (points away from) the comet and not directly away from the Sun.. Besides dust stirred onto the lander by solar forces, I suspect it might accumulate dust through electrostatic forces.
  20. OT If anyone can give me some insight or direction concerning my inability to get the quotes function to work or why I can't paste, I'd be appreciative. Cursed machine! @@$%~@%!^~!!! Studiot: Are you referring to a drum with the Amerindian diaphragm reference? If so, I say yay yay. One for the money, one for the funny. Moth: I'd say yes, a chimney is a machine. Not only is magnitude altered but the direction of the exhaust gasses as well. Much of the idea of "machine" is academic and the traditional 6 from the Renaisance mentioned in the OP are an enhancement of the 3 of antiquity. (Archimedes' lever, pulley, screw.) Add to that confusion the qualification of "machine" in some definitions that its work be 'useful'. Can we then not have a useless machine? Professor be damned!! I may be a necromancer but I'm no mind-reader. As we say, so shall it be. A machine is as a machine does.
  21. Acme's the name, impressing the game. My calendrical impairment notwithstanding, what did you think of my answer?
  22. The question put forward by the title is a literary non sequitur. "We" simply can't know such a thing. As to admiring it while we can, "we" readers are in no danger of losing sight of Luna while we live. (Notwithstanding its possible destruction by impact. Even so, if humans survive such a thing we can still admire the debris.) I admire what I want ,when I want; thank you very much.
  23. Crito, we owe a cock to Asclepius. Please, don't forget to pay the debt. ~ Socrates
