  1. Or possibly a slight mangling of the rotating mirror method of calculating c.
  2. Yes, I believe UFOs exist. I don't believe that they are alien visitors.
  3. You might want to read The Man Who Tasted Shapes by Richard E. Cytowic
  4. An ideal solenoid has no field outside of it, so that part of it was incorrect, and thus anything derived from that notion is incorrect. Of course, a real (i.e. non-infinite) solenoid will have a field outside, since the divergence of B is zero - but the field is much stronger inside.
  5. The velocity with respect to what? You said that you can measure if the velocity changes. Velocity is measured with respect to something else - my point was: how do you know if you are accelerating or if that "something else" is accelerating? That measurement is insufficient to tell who is accelerating.
  6. This is the first hurdle to overcome, not a much later one.
  7. Basically, if Newton's laws work, you are not being accelerated.
  8. Depends on the gas. Some atoms or molecules are gases at room temperature and pressure. Some need to be heated. Depends on the boiling point. (Technically, everything has a vapor pressure, so you will find some gas of even a metal at room temperature - but it's a very, very small amount compared to the other constituents.)
  9. There are two types of people: those who categorize people into two types, and those who don't.
  10. I decide? Good. As a refutation of relativity, it's crap. Game over. Thanks for playing. The page loads now that I am on my home computer. Your clocks are 15 light-seconds apart. All you are doing is measuring that they are 15 light-seconds apart. An observer at any position will be x light-seconds away from one clock and 15-x light seconds away from the other. One reading will always be T-x, and the other will be T+x-15 (ignoring your offset). When you add them, x cancels out, so all observers see 2T-15. Wow. You've discovered algebra. <yawn>. Note that you have assumed Galilean transformations. Relativity hasn't come anywhere close to your dicussions, so I don't see how you can conclude that it's wrong.
  11. A bar walks into a man... ooops! Wrong reference frame. How about science cartoons? Non-science ones
  12. Yes, there's a pipeline from Prudhoe Bay to Valdez, in Alaska. But I'm pretty sure that any pipeline running through Canada is natural gas.
  13. Copyright ownership does not imply orginality. You can sell or transfer copyright ownership. Copyright of cartoons in the New Yorker magazine, for example, are owned by the magazine, but were created by the individual cartoonists.
  14. This year's group is Brood X, but as the numbering implies, there are many different broods. There are also 13-year cicadas. But brood X is the big one, and in full force in the mid-Atlantic. The chorus sounds like the phasers from the original Star Trek, and the mating call buzzing and clicking has started. More info here
  15. I think that's a gas pipeline(s) that goes through Canada.
  16. What circumstance do you envision would lead to that? It would mean either you paid someone for the copyright or the work was created as part of the normal course of their job, with you as the employer (i.e. a work for hire). I don't see how either gets you around a rule saying you have to do original work.
  17. We're already using that electricity. You have to build new plants for the hydrogen electrolysis. So, in the US at least, that kinda rules out nuclear for the time being.
  18. How is that, if you have to burn fossil fuels in order to get the hydrogen? Your pollution level is the same (or worse, because the efficiency of the processes isn't 100%)
