Really? Is slashdot now making fun of the nerds for being smart?
You must be a ton of fun at parties. In this case, the poster is actually making fun of *himself* for not being as smart as the OP (or, possibly, simply for not being educated in the field the OP is talking about), not of the OP for being smarter than him. At worst, it is a comment on how specific and arcane the language of a specific field can become to the outside observer.
They have a lot of directionality. The physics is not completely understood, but gamma ray bursts are focused along a fairly narrow line in two opposite directions.
Orbital speed is ~7.7 km/s at that altitude, so unless it is traveling in the same direction they are, the most probable speed was somewhere upwards of 7 km/s (if it was orbiting in the other direction, 15km/s). Enough to put a hole in just about anything. That's assuming it was in orbit, if it was a meteor and not manmade, it could have been going almost any speed (but probably still a few km/s at a minimum).
How does the ninth amendment even apply, in any way? The FOIA isn't in the constitution at all. Anyways, the SCOTUS found a long (long) time ago that the 9th amendment only applies to the federal government and isn't enforceable against the states, so even if it was in some way relevant, it still wouldn't apply, as this is a state-level FOIAs that the ruling was on.
Same thing happened to the neutrinos as happened to the photons. They cooled down. Currently, the neutrino background is ~1.7K, I believe (they're a bit cooler than photons as photons decoupled from matter much later in the early universe than neutrinos did). Neutrinos are, on cosmological scales, treated mostly the same way photons are (they behave in a similar fashion). In any case, the current energy in neutrinos is about ~60% of that in photons, and photons are about 4 orders of magnitude below the energy in dark matter.
We can also predict how the universe would evolve if neutrinos made up the bulk of dark matter. Since it didn't evolve that way, dark matter has to be something else.
Since AMD drivers are total garbage, why bother?
Might as well stick with a card I can actually use.
You know, I keep seeing people say this, yet the only manufacturer I've ever had driver trouble with was Nvidia, on both Linux and Windows. So, you know, YMMV.
How many people use GPIO on these boards? A small, small minority. Pretty much everyone else who's not content with a media center will want a decent CPU instead. It's a fully fledged general purpose computer. Not some android toy, but something that's good enough to be one's primary machine with a real OS.
The entire target market on these things is for people who use GPIO. Sure, lots of people who don't care about that end up buying them because it's a cheap tiny low power computer (half the cost of your suggested replacement), but they are designed around being device controllers, not media center PCs.
Firewire goes to 30GB/s and 45 watts (30v @ 1.5 amps) and you can daisy chain it. Seems like a better idea than inventing a non-backward compatible serial port and pretending it is somehow related to USBs of yore.
Do you have a source on the non-backwards compatibility thing? Because the USB spec release[PDF warning] for the new USB SuperSpeed states it will be.
I should add that the newest FireWire specs only go up to 800mb/s, so also a source on that would be nice.
Maybe I missed it but the picture gives me a vague impression that waves have something to do with it but I didn't see them mentioned? I suppose the water movement wouldn't be much use though.
No, it has nothing to do with waves. It uses the ocean's thermal gradient as a power source: because there is warm water on top, and cold on the bottom, we can use the difference to generate power (much like heat from a conventional power plant). Keep in mind it won't be very efficient, since the temperature difference is relatively low, but since you have quite a lot of seawater to utilize, efficiency isn't terribly important.
I don't quite get why expanding faster makes temperatures more equalized, but I don't doubt the math works
In order to be in thermal equilibrium, two objects need to be close enough together at one point in time to, well, touch, basically (within each others light-horizon, specifically). Without inflation, parts of the microwave background far apart wouldn't be within each others horizons, so they wouldn't have been able to interact and equalize their temperatures. Inflation solves that by making it so everything was much much more dense in the very early universe, so temperature across the entire (visible) universe could equalize, then expanding very (very very) rapidly so that bits that were within thermal contact are now separated (or rather were separated at the time of microwave background emissions).
I beleive the leading guess is that the universe expands to its limit, then gravity asserts itself, causing all matter in the universe to compress into an unstable singularity.
No, current observations and theories place the energy density of the universe at below critical value, i.e. it won't re-compress and will keep expanding forever. Actually, thanks to dark energy, the expansion is accelerating (although since we don't know what dark energy is, yet, whether that will continue or even reverse is a very much open question).
It should be pointed out that EA did lose a ton of money last year ($45 million quarter 4 2012, $381 the quarter before that). If they keep on track they should go out of business pretty quickly.
But in reality, Android phone makers who want to include must-have Google apps such as Maps, YouTube or Play are required to pre-load an entire suite of Google mobile services and to give them prominent default placement on the phone,â the group argued.
Isn't this what Microsoft was accused of with regard to Internet Explorer, and what they were just fined $700+ million for?
No, Microsoft was accused of integrating IE with Windows so it could not be removed. Google does not integrate any of their products with Android by default. In fact, to get Google applications the company making the device has to comply with Google's certification process.
What the companies are complaining about is that to get the "must have" applications, you need to pre-load Google's services. In other words, they are apparently complaining Google isn't giving away enough stuff with Android. Never mind there are quite a few alternatives to all those applications (Amazon store, 3rd party Youtube and map apps, so on and so forth), they are hardly "must have" at all.
It's more complex than that. You want a laser in a frequency you can generate easily, focus well with optics, and that will not be absorbed by water vapor, gas, or dust. Higher frequencies don't necessarily net you any kind of energy efficiency yield (while per-photon energy is higher in higher frequency, you can just produce more photons for the same energy cost, so there is not efficiency gains from the physics). This [PDF warning] report gives quite a lot more technical details (including, yes, they do use IR), but not all of them.
But planes have been hijacked with knives before 9/12/2001.
Fixed that for you.
Aye. That fact pretty much makes the whole TSA utterly pointless. No one is going to even try hijacking a plane, not anymore. Blowing it up, maybe, but not hijacking. And there are vastly easier targets if you just want to kill a few people with explosives (the queue for the security checkpoint, for example).
The largest we've seen is about 1/100th of that (very roughly, estimates for the largest we know about are about 17 billion solar masses, or 3*10^40kg). So, like I say, probably there isn't a black hole that big.
The opposite of what you said is to make every variable 0, which yields invalid results just like your infinite variables yield invalid results. It's fine to speculate some numbers, but you can't use zero or infinity as those speculated numbers.
Not sure what you're even talking about, setting the numbers to 0 works fine (zero gravitational field is well defined, even if it doesn't exist anywhere). And deriving equations and examples from infinite cases is a routine practice in physics. Many equations are derived from such cases (indeed, quite often you find that assuming a non-infinite field makes deriving an actual equation impossible). If you like, you can pretend the field is simply incredibly large relative to the scale you are interested in. Thats basically what is being said anyways.
Regardless, all we need is a field of such size that at some distance r from mass M escape velocity equals c. We don't even have to guess what that is, in fact, if we stipulate a_g=1G=9.8m/s^2. Swartzhschild radius is 2GM/c^2, a_g=GM/r^2, so M=c^4/(4G*a_g) or a mass of 3.1*10^42kg, about 1/2 the mass of the whole Milky Way galaxy. Larger than any black hole we know of, perhaps, or perhaps larger than a black hole could realistically form, but again: you can definitely have a gravity strength of 1G at an event horizon for a black hole, theoretically.
Not necessarily. Imagine an infinitely large gravitational field (caused by an infinite object an infinite distance away, so that all field lines are parallel to each other). It should be obvious that the "escape velocity" at any point in that field is infinite (no matter how fast you are traveling, you will always stop and start "falling" at some point less than infinity).
Of course, thats a fictional example, but it's a reasonable approximation for an extremely large mass a very long distance away (such as in the case of a supermassive black hole) and shows that escape velocity is not proportional to the gravitational acceleration.
And the market will show that the vast majority of gamers could not care less whether an Internet connection is required or not, so long as the game is fun. And since game development is all shifting towards multi-player anyway,
Fun fact: it's actually not. In fact, it's actually moving away from multiplayer-in-everything that was so common a few years ago. The percentage of games without multiplayer on consoles has almost doubled.
That is absolutely not how gravity assists work. Gravity assist work because the planet you are "assisting off" is moving: you can rob a little bit of that kinetic energy to give yourself a boost. But a "gravity highway"? No, you can't do that.
So, what are you most worried about? Health risks? Lower with nuclear (part of the reason it saves lives). Environmental impact? Lower with nuclear. Cost? About the same, coal is only lower because the power companies haven't had to pay as much in regulatory fees or health costs (overall, the total cost of coal is higher, especially over time).
Slavery does not have to be involuntary, nor non-profitable. As others have pointed out, people in ancient Rome would often sell themselves into slavery for money. Force is not a necessary condition for slavery, although historically it usually is.
Sort of. It's the edge of the actually visible universe: it's light from the moment (well, it wasn't a moment exactly, but it was nearly instantaneous on the scale of the universe) when photons stopped being scattered by matter, and started free-flowing (this is known as the "surface of last scattering"). Since some points were slightly hotter than others, they produced slightly different distribution of photon energies. Black body radiation (which is what the background radiation is) follows a well-defined curve of photon energies, so from the photons we observe today, we can deduce the differences in temperature in different spots then. The usual picture is of that temperature difference, after scientists have processed out all the foreground noise.
Technically, the "edge of the universe" is a bit further away than that, but we can't see that far, since light from that period of time was absorbed by all the ionized gas that filled the universe.
