  1. As noted above, you don't need mass to have momentum, just energy. Photons can bounce off things somewhat like a ping pong ball bounces off a table, and impart momentum. As for the more exact "how" IIRC all momentum arises pretty much in the same way in QM, but I won't go there.
  2. I read about this last night and was pretty thrilled, a great leap forward in stem cell research.

    SNF? Skilled Nursing Facility? Saturday Night Fever?
  4. Aaagh, cellphone camera videos! The goggles, they do nothing! The sound quality isn't exactly awesome either. Also, nice necromancy, seeing how this thread had been dead for over four years Somewhat related, filmed with a digital photo/video camera. The "intense bass" of the report is more apparent, imo. And that's just perchlorate and aluminum, rather than nitrate + Mg.
  5. Rene Descartes walks into a bar, and the bartender asks, "Would you like a beer?" Descartes says, "I think not," and vanishes in a puff of logic.
  6. I like the fact that in those dense articles one can often find this notice at the top: "This article may be too technical for most readers to understand, and needs attention from an expert on its subject. Please expand it to make it accessible to non-experts, without removing the technical details." It's a very visible indicator of the "denseness", encouraging further edits, rather than just something hidden in the article history.

    Relativity "works" always. Actually, effects of relativity are especially evident at small scales, particles' lifetimes affected by their extreme velocities and so forth.
  8. Very little English spam lately, but I keep getting tons of mail in languages I'm not the least bit fluent in. There's no fun in spam if you can't tell what they're trying to use as an excuse to give them money or download a virus or two. :| For example "Josh Woodcock" is trying to tell me something very important, but my Turkish is a bit rusty.
  9. Is the "another corner" an adjacent or an opposing one? Does the table have to be completely covered by the tablecloth? Actually I'm not sure if even then there's just one correct answer.
  10. Seems like tungsten hexafluoride is pretty much as dense as a gas can be at STP, and it has a density of 13.1g/L vs. water's ~1kg/L. While an object will fall much slower through such a gas than it would through air the density would have to be dozens of times higher for swimming.
  11. There is no center of the universe in the same sense as there is a center of a conventional explosion. Current evidence indicates that space itself is expanding, much like a balloon's surface expands when it is inflated, sort of dragging matter with it, which makes it possible for the universe to have a diameter greater than 27.4 billion light years. Edit: Severian's link covers the more technical aspects of this.
  12. Especially around the holidays there's lots to do at the mall. Like tackling the mall pianist and playing the Star Wars Cantina Band theme on the piano until security comes to drag you away.
  13. It's "less indeterminate" than [math]\frac{0}{0}[/math] though.

    Mirror's Edge

    Too... many... games. While a huge game rush just before the holiday season is nothing new, this year amazingly many of the games are actually good. I'm looking forward to the PC release of Mirror's Edge, but I'm guessing it won't be any time soon.
  15. That sure beats 6 months of military / 12 months of civilian service. Gender equality and all, wow!
  16. Well there's the Nuremberg Code and the 1974 Declaration of Helsinki. As for animals in particular I'm not sure if there's an international code.
  17. Chemistry was pretty much always my strongest subject in school, but eventually I decided that it wasn't going to be a career for me, at least not on an academic level. I like music as well, but the actual studies would probably be too mechanical for me. Starting a career in something can take a lot of fun and freedom out of it, so you should really think it over carefully. I don't want to sound too materialistic but one thing to consider is whether you can make a living out of it. But I agree it's OK to study something just for the sake of getting better at it or learning more about it in general, before deciding whether to go for a related career.
  18. Awesome! I've always wanted to do something like that but as noted stuff like TCPO or luminol isn't exactly easy to make at home.
  19. UTFSE is an acronym. It is crucial to remember that there is a search option. While the indicator for said search field is quite small (much smaller than a football field, depending on your monitor resolution of course), not using it can cause unnecessary threads. In other words, I think we have like over nine thousand threads about this.
  20. The newest Simpsons episode's intro was hilarious. "Six votes for President McCain." "Hey, I only meant one of those votes for McCain... this machine is rigged!" Anyway, the statistics support Obama's victory to such an extent that should he lose some people are likely to expel blocks of masonry-related ceramic material from their rectal cavities, so to speak.
  21. I know YT better than I know Biden and Sarah Palin is... well, Sarah Palin. So YT it is, duh.
  22. Antimatter is just an extension of sorts, from antiparticles, so that's not a very good reasoning.
  23. If we're talking about specific applications of theories I'll have to agree on the transistor.
