  1. Re:The good news is ... on Smithsonian 'Toned Down the Science' In Climate Change Exhibit · · Score: 1

    250 years ago, the Smithsonian was under water (or in the middle of a swamp, anyway.)

    Isn't that essentially what Unisys did with the .gif format?

    Or was there some other subtlety in that case?

    MTV is to music as KFC is to chicken.

    True. Both make me vomit.

    Although in the year 3000, everyone will just say aks, and assume that ask is a archaic pronunciation.

    Where I once managed to think in "tree structures" where multiple solutions are being thought about; I had only -one- way of thinking when taking this drug.

    That's interesting to hear from someone who's been on and off the drug.

    I noticed similar behavior back working at a day camp in HS. We'd get the same kids year after year, until the aged-out at 12. Sometimes you'd have a very bright kid who was hyper and hard to control, but you could give them a difficult task or puzzle, and they could focus for hours (chess, checkers, and connect-four against the adults, for example. The kids I'm talking about would crush any of the other kids in no time.) Unfortunately, too often we saw the brightest kids back next summer, drugged up and seemingly dim.

    Granted, not a scientific study, just an observation.

    20 light years.

    At 10.8 miles/s -- the current speed of Voyager 1, 373,000 years (I rounded -- alot).

    If we can jack that up to .25c (a considerable feat), it falls to 80 years, but the crew will only age 79 years or so.

    Now, if we double that to .5c (a damn-near impossible feat), it becomes 40 years, with the crew only age 36 years, provided they don't become goo from the massive g force they will feel getting up to .5c.

  7. Re:SETI failed? on Extrasolar Planet Could Harbor Life · · Score: 1

    The planet is only 20 LY away. So we could send and expect to receive a signal in a human lifetime.

  8. Re:A question of perspective on Global Internet Censorship On the Rise · · Score: 1

    Your point is somewhat contradictory. You say "obey zoning laws," but then say that censorship regulates usage - "what you can and cannot do with your property."

    Zoning laws by their very nature regulate what you can and cannot do with your property. If I want to run a retail business out of my home, I can get away with it only as long as the city doesn't find out. I can't open a cafe, or a bed-and-breakfast, or a photography studio, or a road-side stand under the zoning restrictions.

  9. Re:if it requires latex gloves on How Far Should a Job Screening Go? · · Score: 1
    I was fingerprinted AFTER I'd already accepted the position.

    Excellent point. I've been fingerprint screened for two jobs - a day camp counselor back in HS (they screen for pedophiles) and when I worked at GSFC/NASA -- and at GSFC it wasn't even my company, but the government. Both screening were after I had already gotten the job.

    I've also been drugged screened, again, after I had accepted the position.

  10. Re:Strange ice on Strange Alien World Made of "Hot Ice" · · Score: 2, Informative

    There is a problem with the UVA page -- Ice skates blades aren't flat in any dimension, so you get nowhere near 20cmx3mm in contact when gliding. A hockey skate probably has 8cm of length in contact, and a figure skate about 12cm. The blade itself is hollowed down the middle, like an upside-down U. A very shallow hollow will have a 7.5cm radius, a figure skate about 4-5cm, a normal hockey hollow is closer to 2.5cm, and a suicidally deep hollow has a 1cm radius (But its all a matter of personal preference, really.)

    Effectively, a hockey skate will actually have about 8cm*1.5mm = 12 sq mm in contact with the ice, not 60 sq mm. That's a 5x increase in pressure over what the UVACD says, meaning instead of 12 atms (their number), you get 60 atms. Still not enough to raise it one degree (there are other factors -- frictional melting and the temperature of the blade), but their assumptions are wrong.

    The blades also bend ALOT when skating, more than you might think. Whenever there is a turn cut in the ice, the blade deforms to match it. And bending a metal creates heat.

    As an aside, the best ice for skating should be around 18F (as measured by return brine temp, so the surface will be a few degrees warmer), with an ambient air temp of about 32-40F, and 20-30% relative humidity. Above 40F or 30% humidity, either the surface starts to melt, or water condenses on the ice.

    Now that was completely unrelated to the topic at hand, but I had to rant. Sorry.
