    Indeed. It would be an impossibly large volume of water. That's why it's viewed as one of the miracles in the Bible -- a miracle being something that happens but does not follow natural laws. Something that can only happen if God decides to suspend the laws of nature and make it happen.

    I think it's much more likely that some people saw something and utterly misunderstood it. That would appear to be a common human failing, even today.

    Perhaps it wasn't 17000 feet tall at the time. Simply because the earth currently has "deep" oceans and "high" mountains doesn't mean that it always did.

    I find it even harder to believe that the remains of a wooden boat would remain on a mountain long enough for such radical geological changes to take place.

  3. Re:Incorrect... on Video Projector for Home Theater? · · Score: 1

    Car headlights are deliberately trying to not have an even light distribution - that's what all those pretty patterns in the headlamp cover are for.

    The "pretty patterns" aren't so much to not get an even light distribution as to shape and focus the beam. I'm pretty sure the designers don't care very much about small irregularities in the headlight beam, so long as the beam is directed in the proper direction and maintains good overall brightness.

    There's a reason projectors (overhead or video) use fancy bulbs. They need lots of brightness and even lighting.

    My living room needs a lot of brightness and lighting. My car needs a lot of brightness and lighting.


    Even lighting. Point your car headlights at a wall or garage door and observe the pattern. It's not even pretending to be an even light distribution. Your living room lights are somewhat similar, but more importantly they don't have the proper spectrum to accurately, consistently represent colors.

    Projector bulbs are high-precision instruments. Car headlights and living room lamp bulbs simply aren't.

  5. Re:What if ... on UK Releases Global Warming Report · · Score: 1

    This is true, but the part of the ice that is above the waterline is entirely made up of the extra "structure that ... is less dense than liquid H2O". Hence, when melted it will compact back into liquid and NOT raise the sea level. It's a question of mass, not volume!

    Please see my reply to the peer of your comment. This is simply not true. Because seawater is denser than pure (for certain values of "pure") water, melting ice in seawater will take up more volume than the displaced seawater.

  6. Re:What if ... on UK Releases Global Warming Report · · Score: 1

    The mass of salt water displaced is equal to the total mass of the iceberg (above and beneath the waterline).

    True.

    So except for the small difference in density between salt water and fresh water, melting an iceberg doesn't raise the sea level.

    The masses are equal, not the volumes.

    subscript s -> displaced seawater
    subscript i -> iceberg
    subscript w -> melted iceberg

    Mi = Mw = Ms
    Vw*Dw = Vs*Ds
    Vw/Vs = Ds/Dw = (1.026 kg/m3)/(1.000 kg/m3) = 1.026

    Thus, the volume of the melted iceberg will be 1.026 times, or 2.6% greater, than the displaced seawater.

    A 2.6% increase is non-zero, nor can it be made zero by hand-waving.

    Another thing to consider is that this melting ice will reduce density of the surrounding water closer to pure water levels, causing existing ice sheets to require increasing volumes of displaced seawater to support their weight. This must also raise sea levels.

  7. Re:What if ... on UK Releases Global Warming Report · · Score: 2, Interesting

    ice from the north pole displaces just as much water when it's ice as when it's water - because it's floating, melting that shouldn't change the level.

    BINGO! You are correct. But acknowledging this fact would mess up a perfectly dandy argument in favor of the Kyoto protocol. That's why it tends to get conveniently overlooked...

    Actually, as posted elsewhere, this is incorrect. Frozen H2O forms a structure that actually is less dense than liquid H2O, which is why ice floats.

    Don't forget that much of this ice is above the waterline, which once melted would transfer below the waterline, raising sea level.

    .zip is vicious too. I've seen several copies of a virus that tries to look like its being sent from the staff of your domain, and says that you have to unlock your email account because of abuse. The instructions are in a .zip archive and the mail provides you with a password to "unlock" the archive.

    This is just to prevent anti-virus tools from scanning the compressed archive. If the virus is known and detectable by the ZIP file, once you supply the correct password, the virus should be detected when being extracted from the archive. (Assuming your scanner supports scanning of new files that hit the disk, and this feature is enabled.)

    This tactic wouldn't seem to be all that effective. The more manual steps you give the user, the less likely they'll be able to do all of them to completion without goofing up, and the less likely the lazier ones will want to bother.

    If you read 'The Light of Other Days' by Arthur C Clarke & Stephen Baxter you'll get a good insight into the possible consequences. While the book is centred around the idea that wormholes can be used to view anyone at any time, knowing what people think would have the same effect of first causing terrible unrest but eventually destroying barriers and allowing everyone to work together. It's a very interesting read and I feel that every day we get closer to that reality.

    Indeed, the wormholes eventually allow groups of people to share their thoughts, but the obvious difference there is that the sharing of thoughts is bi-directional and only possible after an implant.

    I'm sure once a tool is invented that allows reception of an individual's thoughts or motivations, a small subset of society will monopolize and abuse it before it ever becomes a commonly-available tool.

    So I read the article on deuceofclubs - what exactly does that have to do with Free Speech? Sounds to me like Trademark or copyright violation or maybe even fraud...but not free speech.

    To me, this particular case illustrates that there's a very nebulous line between intellectual property, trademarks, copyrights, and free speech, at least when it comes to art.

    Making a statement in art seems very much like an aspect of free speech. Is that only when the art doesn't cost anything? When you're an artist that actually wants to make a career out of creating art, does that mean you're not allowed to parody, satire, or generally make a statement using aspects of our society that happen to be trademarked or copyrighted?

    Part of the point of this was that at the same time, U2 was using other's copyrighted content without reimbursement in their own concerts. They'd no doubt argue that this was done for their art, but apparently other artists aren't allowed to do likewise, not when it involves U2 trademarks an content. (Note that this was mainly a spat between labels, but U2 declined to make a stand on principle when it came to this particular spat.)

    Anyway, this is a bit off-topic, so I'll not belabor the issue.
