Can someone with greater knowledge than I explain how the camera survived re-entry, or is there no re-entry at that altitude yet?
It's less a question of altitude than velocity. The solid rocket boosters cut out and fall away at much less than orbital velocity; most of their job is lifting the heavy fully-loaded external tank off the pad. The expended boosters start off with comparatively little horizontal valocity, and no vertical velocity at the top of their trajectory; they fall effectively straight down from a relatively low altitude, and reenter the atmosphere (which reduces and eventually reverses their acceleration) before they can build up much speed.
It's worth noting that SpaceShipOne followed a similar velocity/altitude profile, and thus also didn't encounter significant reentry heating.
Studies show that the net is displacing television as an entertainment option, especially among coveted younger viewers. I love the kind of thinking that responds to this threat by trying to make sure that television remains as unlike (and separate from) the net as possible.
I barely watch TV anymore, and commercials are one big reason why. I'm so used to being able to choose exactly what I see and hear that I find the idea of passively accepting ads unacceptable; the annoyance level spoils shows for me. Note that I *am* willing to pay for programming; I'd just rather do it directly, through subscription fees, than have content force-fed to me on the remote chance it might make me buy something.
I've found the nitpicking he's gotten about this very unfair. We ultra-hip tech gurus call them "pipes", after all. Is the guy so far off base using a near-synonym to express the same idea?
Given that fossil fuels are just biologically condensed solar power, I'm not sure there's room for a "first" here.
For that matter, wind is driven by differential heating of the Earth's atmosphere by the Sun, so Magellan might have a claim on being first with the boat variant.
Yes! I am surprised that more people haven't bitched about this - and even then, it's always because of how he appears (small, mobile, making goofy facial expressions, etc, etc) and never that the conversation with him is damn near the same conversation Han had with Greedo just a minute before.
I'm with you on this. It's so obvious that what we're seeing is the result of a last-minute script rewrite in the origional where the dialog with Jabba was reassigned to Greedo. And then Lucas thought nobody would care that the same dialog gets used in the very next scene in his reissued version.
I lost interest in the reissued version at that point; if Lucas doesn't care about it, why should I?
Or have they managed to get the jumbo to fly at the speed of light?
Yes; but it's operated by United, so what with the two-hour-late departure and sitting on the taxiway at your destination for another hour waiting for your arrival gate to open up, you still miss your connecting flight.
It's close enough to being a vacuum that standard university lab equipment couldn't detect the difference between it and a true vacuum. To give some idea of how little of it there is, each of the Apollo missions noticeably increased the lunar atmospheric pressure with exhaust gases from the descent and ascent stages.
A recently-dead corpse will spout blood and water from a chest wound, as Roman soldiers assigned to crucifixion duty would presumably know well. So stabbing a body in the chest wouldn't make a very good test for life (talk about observation influencing the observed). I side with those who read the "already dead" language in the Gospel of John as a later insertion by someone unfamiliar with the mechanics of crucifixion.
That's often read as a gloss on the original text, written by someone who didn't understand the mechanics of crucifixion. Why stab someone who's already dead, especially if he's going to spray blood and water all over your nice clean tunic?
That's "crucifixion", not "crucification", just for the record. As in "to be fixed to a cross (crucis)".
Crucifixion was in fact a fairly common form of punishment throughout much of the Roman Empire. It was both a particularly painful and notably humiliating way to die; victims often lingered in agony for days while being jeered at by passers-by. Few understand that Longinus did Jesus a huge favor when he stabbed him in the side with his spear.
It will be interesting to see how this punishment works out in Roma Victor. As the player will feel no pain, and loses only a week of game time while on the cross, the real punishment will come if others in the game take having been crucified as a mark of shame rather than a boastworthy accomplishment. Given typical online-game culture, I fear the latter is more likely.
there are bands in Jupiter's atmosphere that are comparable to Earth's atmosphere, past and present.
There is certainly a broad layer where the pressure and temperature are roughly Earthlike. However, there is nowhere in Jupiter's atmosphere where the composition is more than vaguely similar to Earth's primal (prebiotic) atmosphere, and nowhere similar to Earth's current atmosphere at all. There is effectively no free oxygen in Jupiter's atmosphere, and only tiny traces of anything other than hydrogen and helium. Most of the traces are simple alkanes and water.
Now if we can just develop some sort of automated tool that obsessively scans a list of webpages for updates, leaving inane comments when it encounters a new piece of content, we can all finally leave behind the drudgery of the web and enjoy more free time.
My favored analogy for a sprawling, unplanned, grew-by-accretion software product is the Winchester Mystery House in San Jose, California. So the chosen analogy happened to strike me in the worst possible way. I've worked on and with too many WMH projects already.
Well no offense man, but I'll take Von Braun's argument over yours any day of the week.
Do as you like; but note that I, unlike Von Braun, am not defending my argument in order to obtain billions of dollars in government funding for my pet projects.
had shown they can man and supply outposts in much harsher conditions.
And where, exactly, had the Army been maintaining outposts in conditions harsher than those of hard vaccum, 300K day/night temperature variation, unfiltered exposure to solar and cosmic radiation, and a nearly complete lack of extractable life-support volatiles in the soil?
Why is it that every new PMM for the last two decades has involved permanent magnets? Is there some kind of mad-scientist cabal that decrees these things? Will the fashion turn to something else soon, like, I don't know, materials so bouncy that they rebound with more energy than they hit the surface with? (Name that classic SF story.)
Seriously: Editors, please shitcan perpetual motion machines before we have to waste precious seconds on them. When a real PMM is possible, you'll know it's happened because suddenly the universe will have stopped working properly, and you'll be instantaneously and very thoroughly dead.

This is why I so appreciate Perl's "taint checking" mode. In this mode, *all* data obtained from external sources -- http payload, env, read from a file -- is considered tainted until it's been the object of a regex pattern match, which turns off the taint bit. Tainted data cannot be used in any action that will have external effects -- writing to output streams, calling system execs, etc.
It's not perfect, of course, but it's alerted me to potential security problems dozens of times.
I once managed to deflect a corporate decision that seemed certain to lead to disaster by saying in a meeting with the CEO and other bigwigs "Guys, I'm having a Morton Thiokol moment, here." Enough of them got the reference (and saw that I meant it) that they actually started listening to me.
Yep, I probably blew this one. I was repeating a story I heard from a materials professor back in college, but he may not have thought it through, either.
Damn, another good party conversation-starter down the drain.:P

this technology won't turn out to be just so much vapor.
Until the heat sink fails.

Well, I'll also argue that maintaining a base on the Moon is logistically more difficult than anywhere you can name on Earth.
My brother, an Army veteran, claims that Fort Benning, Georgia is far less hospitable than the surface of the Moon, by the way.

I called it a PMM in my post because the linked article blathers on about over-unity efficiency, which is just another way to say PMM.
Bing! Give the man a prize, that's the very story I was thinking of -- and in fact I read it in that collection, too.
I should have known Wikipedia would have the answer; it always does. Thanks for the pointer.
*laugh* I'd forgotten about that one! You score full credit, but I actually had a textual short SF story in mind.
