  1. Re:Math Forfront on Mathematician Solves a Big One After 140 Years · · Score: 1

    An equation can be said to describe a thing(maybe approximately;). People interested in a thing often find it useful to have a description of it. They have two choices: use an existing description, or come up with their own.

    So, how often does human technology follow math, and how often does math follow human interest?

    I actually thought I read your original post rather closely before I asked the question, because it is a stupid question to ask(and could be interpreted divisively) if you have already mentioned that you did a sleep study. Re-reading it, I still don't see where you mentioned any testing or observation. What am I missing?

    What you are getting it is that productivity can't be measured in hours worked. This shouldn't surprise anybody.

    That's that's a big part of the reason the dollar is falling BTW, people in the US are getting more dollars per abstract unit of productivity than people elsewhere are getting units of their currency, and relative currency valuations are shifting to make sure that each unit of productivity ends up being worth about the same amount, regardless of origin. There are also structural economic reasons(government subsidies, taxes, differing regulatory regimes, stuff like that), but those should tend to impact parts of the economy, and the current slide seems pretty broad based(it is also measurable in commodity prices, etc).

    To be clear, I'm talking about equivalent units of productivity. If two outputs are the same, there isn't any reason for a third party to care where about where they came from. If the outputs are not equivalent, you have to scale them to be equivalent before you judge their impact on currencies.

    By volume, lithium-ion batteries only have 1-2x the energy density of nimh:

    How do you prove that you didn't just break into the police station and insert a forged record? What do you do if an accident or a crooked cop destroys your record?

    Authentication is hard. Documents(and information) are only as reliable as the institution that issued them when it is at its worst(If the DMV has corrupt employees selling apparently legitimate but actually false identification...), and to the extent that they are difficult to forge. Beyond that, trust is something that has to be built.

    The more you treat documents as infallible, the bigger your problems are when they, inevitably, are incorrect. This is why limiting their use to where it is necessary is a good rule of thumb - you don't create problems for yourself(problems that are, by definition, unnecessary).

  19. Re:space *exploration* on SpaceX Delays Falcon 9 Launch · · Score: 1

    If we don't have the political will to deal with hunger, is it reasonable to expect that we have the political will to colonize space?

    My comment about chemistry and anti-gravity was a bit tongue in cheek; neither has advanced, nor are they particularly likely to advance, a great deal from the state of the art in 1960(so, decent fuels and no anti-gravity), so advances in other areas aren't going to have an enormous impact on the basic operational economics of space faring. And other than satellite launches and super high end tourism(both of which are being actively pursued in the private sector), I'm not aware of any activity that justifies the fuel costs, let alone amortization of development costs. Nuclear rockets(and such) are interesting, but they currently slam head long into that lack of political will from earlier.

    There is some argument to be made about having humans living somewhere other than on planet earth, but we don't know how to do that in a way that would be useful(which I would deem to be self sufficiency for at least several years, but really, decades), and the problems associated with it aren't problems that you need to be in space to investigate, so(and this is clearly an opinion) it isn't particularly worthwhile to be exercising our ability to deal with the challenges we can handle. It would be neat to have a moon base, and I'm sure all sorts of operational experience and interesting technologies would fall out of such a program, but I don't think the value of that experience and technology, added together with the fact that it was neat, would even begin to justify the costs.

    The way I see it, the OP is standing on the sea shore holding a plank and pointing and shouting. Its easy to see that what he is talking about is compelling, but all signs point to it being, still, a little premature.

    I don't think they are able to effectively maintain the secrecy you are claiming; there are plenty of companies that maintain databases of public records and sell the access to the general public. For example:

    http://zabasearch.com/

    That site will probably have a result for your name(for Americans); if you pay money, you can find out more about the records they got the information from. It isn't going to help you find out about a bad connection that one of their competitors has made, but it gives a sense of what is out there about you, likely to come up in other searches, and *easily* available.

    For companies that won't sell you your own record, the only way that would work is if they were extremely selective about their clients, as all you have to do is have a trusted associate purchase the record from them. If you don't have a trusted associate, you can hire one, they are in the yellow pages under 'Attorneys'.

  21. Re:Summary is misleading on Intel Researchers Consider Ray-Tracing for Mobile Devices · · Score: 2, Informative

    Sort of. You only need as many pixels as the eye can see at the distance the display is used at(and maybe some extra for leaning in). If you jump through some hoops, you can come up with a resolution for a given distance:

    http://en.wikipedia.org/wiki/Eye#Acuity
    http://www.dansdata.com/gz029.htm

    Piggy-backing on Dan's hand waving, 300 dpi at 1 foot is a decent rule of thumb, and waving my own hands, 1 foot is a reasonable minimum distance for a handheld device(I don't imagine most people holding something any closer than this for long periods of time, opinions may vary). So for a screen that is 5 x 10 inches, the benefits for going past 1500 X 3000 pixels rapidly diminish, especially for video/animation. For smaller screens, the pixel count is (obviously) even lower. So if you aren't in need of extraordinary resolution on a large screen, current pixel counts are pretty close to 'enough', especially for screens that don't occupy huge portions of your field of view, so you don't need to factor increases(especially large, continuous increases) in resolution into the comparison.

    So we are at least on the threshold where increases in resolution are done 'because we can' rather than 'because there are obvious benefits', for lots of devices. Plenty of people already don't see a whole lot of benefit in the move to HDTV; Ultra-HDTV or whatever is going to be an even harder sell, as the difference will only show up at very close distances or on very large screens(and plenty of people already have the largest screen that they want as furniture).

    High resolution text is probably orthogonal to a discussion about ray tracing, and it seems to be the biggest current motivation for increasing display resolution.
