  1. I think we reached a possible conclusion in this thread (scroll down to post #23), which apparently is based on the axiom of choice
  2. I think the default is that the first comment requires approval and after that you're good to go (unless you link to more than two URLs). But I would have expected an "awaiting moderation" notice to appear; I've seen those in other blogs. FYI for ecoli and anybody doing science, but especially biology/medicine in their blogs: Science web carnival, Tangled bank http://tangledbank.net/ "The subject should be on biology, medicine, or natural history. We will define those categories very broadly, and it's sufficient that you show some passion for the science of the natural world." You just submit a blog entry by email, and they link to it at somebody's blog. You could even host the Tangled bank, and get lots of traffic going to your own blog. I submitted No Sweat and it was added for Tangled Bank #98 There is also the skeptic's circle blog carnival for skepticism blogs. http://blogcarnival.com/bc/cprof_19.html
  3. Have you tried surplus outlets? One of my favorites is American Science & Surplus http://www.sciplus.com/ I did a search on vial; there were a couple of possible candidates. Their whole glassware section: http://www.sciplus.com/category.cfm/subsection/4/category/42 LabX http://www.labx.com/v2/newad.cfm?catID=116 There may be some more candidates here http://amasci.com/surplus/scisupl.html and, of course, ebay
  4. Angry Harry? Sounds like a character that rat created in "Pearls Before Swine" Maybe a cousin to Angry Bob I think he's compensating for something.
  5. The wind is fairly smooth — comparitively good streamlines. The blades disrupt that, giving you more extreme pressure differences over shorter length scales.
  6. Ah, but it appears that it's also the turbulence that they create that contributes to the false readings. But there are wind farms that don't appear to cause problems. And what early-warning systems do we have in Illinois, anyway? Are we worried about an attack coming from Indiana?
  7. I often dream of many monkeys typing, and then there's a new "reality show" on TV. "It was the best of times, it was the blurst of times?! You stupid monkey!"
  8. Not to an arbitrary place they can't. Wind isn't available with the same favorable conditions in all places. One question I have is this: are the turbines any more of an interference than a building of similar size?
  9. You don't read blogs by mail. You read them on the internet. Oh, wait ...
  10. I just had a Pan-Galactic gargle blaster, so ... yes!
  11. Heh, Heh. The disappearing blog. That never gets old. I was poking around and discovered that you can already find my latest post if you Google using the blogs tabs. It's been one freaking hour. Also, if other places link to you, it improves your standing in certain search engines; I've added an "SFN blogs" category to mine and inked to those blogs on the RSS feed that looked like they had progressed past the "yes I can blog" stage. You might consider doing the same when you have the time.
  12. Ah, but time is an illusion, lunchtime doubly so. Douglas Adams
  13. Maybe some thin gauze on a wire hoop?
  14. I didn't even notice that it wasn't. Moved.
  15. OK, that works, but the link on my page gives a 404-file not found error, and I can't find where I can fix that. edit: If you want to "advertise" your blog, Pharyngula is having a "Blogroll Amnesty"
  16. Is there an RSS option for individual blogs?
  17. <grunt> Thread reopened. The thing about the acceleration is that two observers in relative moton won't agree whose clock is right and whose is wrong. Each sees the other's clock as running slow. Accelerations aren't relative — you can tell if you're accelerating — and you know that's the person whose clock has changed. Thread really closed now.
  18. Since this is posted in "relativity" I'll say that no, time is not an illusion. It can be measured. But there is no absolute time, and how it is perceived depends on the situation. Some aspects of time passing slow or fast to an individua might be considered an illusion.
  19. "Why We Get Sick" by Nesse and Williamson
  20. Trig functions are not linear. The easiest way to do this is to memorize all of the values of cosine for the various fractional values of pi. Otherwise I assume it's fair game that you know that pi/6 gives 1/2, and use the angle addition and subtraction formulae.
  21. Wonder bread. You forgot about the wonder bread.
  22. I believe that you're not making it up. It's awkwardly stated, but is has an element of fact — it's not that cats can only digest meat, but they do require it. "Vegetarian cat food" is an oxymoron. http://www.felinefuture.com/nutrition/taurine.php "Taurine is an amino acid formally known as 2-Aminoethanesulfonic Acid with the chemical formula: C2H7NO3S. Taurine is an essential amino acid for the cat, which means that the cat can not synthesize sufficient Taurine from other amino acids. Humans and dogs, for example, synthesize Taurine from the amino acids Methionine and Cystine. Preformed Taurine is only available from animal tissue, and high concentrations of Taurine are found in the heart muscle, skeletal muscles, brain and eyes of mammals, as well as the meat from clams and oysters."
  23. Yeah, you can see the dipole pattern when you do that. Also, in the sine wave you can see there's a difference between the near-field and far-field field.

  24. Nay, I think it belongs in speculations. But seriously, I agree — unless someone can come up with some actual data to substantiate their claims. While undoubtedly some sick people are kept alive much longer with generally poor quality of life, can anyone quantify this in any meaningful fashion? Think of counterexamples, like hip or knee replacement surgery, that definitely improve the quality of life.
  25. That's some catch, that Catch-22.
