  1. Momentum Conservation on How To Build a Quantum Propulsion Machine · · Score: 3, Interesting

    How does this preserve momentum conservation? In the Casimir effect, the force occurs between two plates; as the plates are pushed in opposite directions, total momentum is conserved. Here, it seems as though you get momentum out of thin air (although energy is reffered to as "being spent", but with no indication how).

    I call shenanignans!!

  2. Re:why would I accept a netbook? on Would You Use a Free Netbook From Google? · · Score: 1

    Why would I want a netbook, free or not? You have to have demand first before you think of price, and even at price 0, demand is not infinite (you've got to carry the thing home, find a place to stash it, etc. - there are costs involved in addition to the price).

    Of course, some people will want it, others won't. Considering there are people who are happy to pay for one, they would be probably be happy to get one for free.

    So no. Even for free, I wouldn't have a use for it. The whole netbook thing is pointless anyways and will soon blow over.

    Overblown, maybe, but far from pointless. It's easier to carry around than a full-blown laptop and it's cheaper and easier to use for working than an iPhone.

    I'm sorry, but your post was almost indecipherable gibberish.

    First you say something about Americans being too insular, then you try to segue into commenting on the site's business model. These things have nothing to do with each other.

    Mr BadAnalogyGuy,

    Please do not log off to comment on your own posts as AC to point out how bad your analogy was. It's as obnoxious as an frenchman in Texas.

    Muscle weighs more. (But it looks better and takes up less space.)

    It's also a lot better for your health. I always gain weight when I do serious exercise. I also gain better lung capacity, better heart capacity, I'm stronger and generally healthier. I'm also thinner. What's not to like? Why would you concentrate on the numbers on your balance?

    Now, if only I could keep it up....

    Yes, you need repeaters every 100km or so, which are powered through the cable by DC current.

    Other than that, I think it just lays in the bottom, yes. These are sturdy cable, they weigh about 10 kg/m.

    That's a very good point: there are many good PHP games that are, by nature, multi-platform. Linux users may want to check those out, as they have a larger user base than games "made for linux", yet don't necessitate you to reboot each time you want to switch from using your computers as computers were meant to be used to playing a game.

  13. Re:What Material Is the Pantacene Sitting On? on IBM Images a Single Molecule · · Score: 5, Interesting

    An AFM image will often look like it has a shadow. In that case, the tip was probably scanning from the right, and it "bounced" after being raised by the pentacene. The shadow size is related to the tip speed as much as the molecule height.

  14. Re:Molecules are made of atoms, right? on IBM Images a Single Molecule · · Score: 0

    So what is a molecule, then? At what size does it become big enough that it's easy?

    This image, for example, shows individual atoms, not in much greater number than the pentacene, although they are attached to a bigger object and can't roll around. These and these, however, seem similar to the pentacene. It's still impressive and cutting edge, just not that new.

    Impressive, so in 1989 they were able to image atoms, and only 2 decades later they already went on to molecules?

  16. Re:A NOOB!! on N00b Boyfriend · · Score: 1

    Creativity, I guess? Forward thinking? Yes, it's a question of semantics, the point being that it's not the same.

    And like I said, it's not that bad. No game is ever exactly by the book, and players of roughly equal level can have an exciting game even if that range is middling, but someone who is used to play will beat a novice so easily that it won't even be fun, and will not learn anything himself. That's the same as in most other sport/games, I know except that what constitute practice in chess is often not chess at all, and boring as hell.

  17. Re:A NOOB!! on N00b Boyfriend · · Score: 2, Informative

    When both players are novice, all patterns are new, and therefore the winner is decided buy pure skill. Then, you may start to learn a few openings, and a few tricks. It doesn't take much to easily beat novices, but you haven't won because of your skills, only because you memorized tricks. There is a huge range where the winner is decided more than by how well you know the opening than by actual skills. Eventually, you get to a point where you already know all the tricks there are to know, and so does your adversary, then most games end up as ties, and wins demonstrate real skill, over and above what's in the books.

    Of course in reality it's not that bad, but the quote is at least half-true.

    The acceleration, yes, but not the speed. That is why the sail has to start so close ot the sun, it needs it to accumulate most of its speed.

    No, a show of hands *is* self-enforcing *but* not secret, and therefore subject to coercion, which is why it is rarely used. The article alluded to the fact that there may be a self-enforcing, secret protocol, without going into details of what it could be. If it exists, it would be a good idea to use it. It would also have been a good idea to include it in the article....

  22. Re:Not doubling the infrared, but slowing by half. on Finally, a True Green Laser · · Score: 1

    You're right, of course.

    My point is, rather, that the slowing of light due to the index of refraction does not absorb energy. It is not a dissipative process. No heating or change of frequency occurs. SHG is a completely different process.

  23. Re:Not doubling the infrared, but slowing by half. on Finally, a True Green Laser · · Score: 1

    Well, some lights simply goes through, some light is absorbed, and some light is converted. The heating comes from the absorption. So yeah, calling it transparency is a stretch. Let's say "if 100% of the energy would exit the crystal, either at its original wavelength or at the new one, then no heating would occur".

  24. Re:Not doubling the infrared, but slowing by half. on Finally, a True Green Laser · · Score: 1, Informative

    Nothing is slowed down. Light always goes at the same speed. Guess its name.

    What happens in a non-linear crystal is that two infrared photons combine to make one more energetic photon. If you can achieve 100% efficiency, then you start with a beam of power P in the infrared and end up with a beam of the same power in green, but only half the number of photons, each photon having double the energy, at the same speed.

    The heating comes from inefficiency (transparency is never 100%) of the crystal, not from slowing down.

    This is all, of course, well-documented in the page you have linked to, but not read. A more specific page might be
