    Really?

    So a hypothetical photorealistic painting of an item isn't any different than the (indistinguishable) photograph of that item, despite it having required far more technique, time, and intent? Is it any different than your memory of the original item? Intent matters in art as well.

    Even better, let's take two blank white canvases, side by side. One is blank because the artist hasn't gotten around to painting it. The other is blank because its Kasimir Malevich's "White Square on White", on loan from MOMA. Which is better?

    1: I'm not at all convinced that's a common belief these days, but yes, if you believe there's no such thing as free will, then the two are directly comparable.

    2: If there is a God, and he gave us free will, he isn't culpable for our actions: the act of giving us free will made us responsible for our own actions.

As such, someone who truly believes in both God and free will can assign blame for the natural disaster to God (assuming that he presets non-thinking things) but not for the human disaster, assuming we have free will.

    Buying Soyuz from the Russians wouldn't really solve the problem, even assuming they would be willing to sell.

Whether or not you believe these are proper goals, it's hard to argue they aren't trying to do something. We can't just dump Shuttle immediately; amongst other things, we've promised to finish ISS, which requires Shuttle to launch major components. But there are plans to replace it with a more reasonable vehicle. They are working on fixing the problem; but these aren't computers. NASA has very, very long lead times.

    My count gives me: 3 Russian-built, one of which was American funded, and 12 American built, all of which were American funded. And unlike the Euro-built Nodes, which are being built in exchange for NASA launching Columbus, FGB was bought by the Americans because the Russians couldn't.

    By the way, Wikipedia isn't authoritative on this; I'd trust NASA's assembly drawings, which are publicly available at spaceflight.nasa.gov, quite a bit more.

    Pirs is a docking module. The trusses, in addition to providing support structure, include photovoltaics to provide power and radiators to provide thermal control. Russian experience is certainly why they get away with relatively small amounts of contribution, but the truth is - they lied about what they could do, financially, and as a result have received significant loans and leeway. Between paying for Zarya and having to purchase a backup for Zvezda because the Russians couldn't/wouldn't, significant financial resources have been expended by the Americans to cover the Russians' asses.

    Russia has the utilization rights to 100% of the Russian portion of the station, and no rights to the rest of the station (the NASA/NASDA/ESA/CSA section). Right now, that amounts to roughly zero, since there is zero experimental capability on the Russian side. Any resources they have are in exchange for the Russian crewmembers time.

    I'm pretty correct on this; the funding is mainly American, and the distribution of resources reflects that. If and when Russia ever gets around to launching RRM and SPP, I'll be wrong, but it doesn't look like that's ever going to happen. Russia has as much up there are they're likely to ever have, while there's quite a bit of American, European, and Canadian segments still to be launched.

    It isn't the American station; it is, however, a station funded mainly by the US.

Of course, looking at that image, SPP is unlikely to ever be built at this point due to lack of funding (according to the Russians), and RRM is unlikely as well (same reason), so shrink the Russian contribution considerably.

    Russia funds/funded around 2 percent of ISS; the remainder comes from the US and other Western countries. Japan funds 13%. ESA funds roughly 9%. CSA funds another 2%.

Probably a huge expense, but nothing gets money out of Congress like "The Russkies are trying to screw us out of our space station!". That and the US would probably declare Russia in default on the loans we've given them over the past decade or so.

    It is by no means a shame that there are probably treaties to stop it - do you really want to institutionalize space piracy?

    You do realize that most of our space program is *great*, right? I mean, the unmanned portion does incredible science, at generally reasonable cost, with very high rates of success. Look at the Soviet Mars exploration program - their first 3 missions failed, the 4th was a 200,000 km flyby, and only 2 of their first 10 Mars missions achieved any measure of success.

    It's just the manned portion of our program that's a little bit screwy, and honestly, we're not much worse at that than anyone else is, we just try to do things everyone else thinks are dumb for reasons having nothing to do with actual science utility, having more to do with the military (see: Space Shuttle program). If we'd stuck with capsules for reentry, we'd probably be quite a bit further than we are; the politics of manned space flight are what's been destroying NASA, not some mythical incompetence at running a space program. It's hard to do good work when middle management (Congress) keeps butting in and telling you to do something different, when the priorities you're being asked to achieve change constantly - any Slashdot software developer ought to have some experience with that.

  17. Re:shutter speed on High-Speed Video Using a Dense Camera Array · · Score: 1

    A CCD can, in theory, operate to infinitely small gaps in time, limited only by the bandwidth of the readout circuitry. However, as your time of collection decreases, you run into signal-to-noise problems; you have a finite, unrelated to integration time, amount of readout noise as well as thermal noise which is proportional to integration time. Thus, while you lose thermal noise when you shorten your integration time, readout noise remains fixed, and thus occupies an increasingly large portion of the read out compared to the signal.

    Basically, you can increase this method relatively infinitely at the cost of signal ratio; the less time you allot for collection, the lower the number of electrons collected, the dimmer the signal and the more interference you'll get from the inherent noise sources.

    However, thinking about it, overlapping collection time shouldn't be an issue assuming that motion in frame during collection is minimal - as that motion increases, you'll start to see 'blur' in your detectors. If you think of each detector as capturing a 'smear' of position in time, it doesn't matter if their 'smears' overlap, so long as during each 'smear' the object remains essentially fixed in position with respect to the detector. That's a seat of the pants guess, though.

    The optimal case would probably be collection time exactly equal to the frame length, but for best results with any scenario you're going to use the one thing any photographer can tell you will provide the best results - proper (i.e. VERY BRIGHT) lighting. If sufficient light is being scattered onto the sensors, even a short collection time will be enough to yield usable signal.

    Recording-wise, two thoughts here: for one, high speed cameras are usually used to capture very short events, so they may only need to store a tenth of a second or a half seconds worth of data. Given that that might only be a gig or two of data, you could quite easily back the CCDs with a RAM buffer capable of holding the entire shot sequence, and then slowly parcel it out to a slower hard drive.

    Second, there's always RAID (whether actual RAID or just multi-drive arrangements isn't important).

    All of the CCDs run at 30 FPS. So, yes, they can scale this almost endlessly (until the parallax variation from non-colocated image captures becomes extreme, basically, or until the trigger timing required becomes too hard to achieve and jitter begins to be large enough to significantly alter your frame timing/sequencing).

    The trick is that A runs on 0.000, 1.000, 2.000, etc. while B runs on 0.001, 1.001, 2.001, etc., C is on 0.002, 1.002, 2.002, etc. (units are frames relative to a starting time), and then the frames are sequenced appropriately (ABCABCABC etc.). This gives a very high frame rate while using relatively low-cost sensors - effectively, they're exploiting parallelism as a way to increase the array's effective sampling rate.

    Basically, if you have N sensors capable of sampling X times per second each, and are capable of accurately triggering each sensor to a high degree of time accuracy, your effective sampling rate can be NX. Neat trick.
