Or, you would need 10 000 comets mashed together into the same volume to have the surface gravity of earth.
...and they wouldn't stay that squished for very long. The explosive rebound of the comet's surface would vastly exceed its escape velocity. Or, to put it more succinctly, BOOM. Unless, of course, you can wrap it in a stasis field, or stabilize it with some other layer of handwavium...
Refrigeration is only one of numerous ways to do air conditioning. The important thing is modifying the air's properties (temperature and/or humidity) to better suit a target application.
In this case, the dinosaur had a sophisticated heat exchanger, one key component of air conditioning. But the "air conditioning" (warming the air) isn't the function they're emphasizing -- they're emphasizing the "chiller" function, where that air controllably cooled blood circulating to the brain.
"...proves that our theoretical understanding about the evolution of planetary systems is correct."
"...will revolutionize theories of planet formation."
Well, which is it? Is it proving that we're right, or proving that we've been wrong?
I expect the answer is that it confirms general aspects of the theory, but challenges specific details. As written, though, the summary seems to contradict the quote.
"We aren't saying that functional, static and strongly typed languages are inherently superior. We're just saying that if you don't prefer them, maybe you aren't really cut out for programming."
As I understand it, getting "captured in a gravity well" is actually pretty tricky. Unless you form in orbit around a larger body, you're most likely by far to just do a hyperbolic single-pass encounter. To be captured, you need to impact the larger body (a very rare occurrence), or dissipate your momentum in its atmosphere (almost as rare), or have some sort of multi-body interaction (probably rarer still).
This is all approximate -- technically, I guess everything orbits everything within its historical light-cone. Almost none of those orbits are anything close to periodic, though.
Thanks, but it's the kind of job I hope I never have to take...
It actually is current that matters, I think -- voltage is important largely for driving rapid changes in current, but if you don't have enough current-generation capacity, your load will limit either your voltage or the rate at which you can make sparks.
I really need to lay in copies of the Foxfire books, too. Again, I view it as hedging against something that I really hope doesn't happen -- but they're interesting reading regardless, and sometimes they'll suggest an idea that's quite useful even in our tech-besotted present.
If they're actually specifying the embargo time in Eastern or Pacific Standard Time, even though most of the US remains on Daylight Saving Time until Sunday Nov 2, the confusion may last a bit longer than they expect.
I love the way the link leads to a "sorry we can't find it, here are some suggestions..." page, with the first suggestion being the very same link, which produces the very same result. Okay, maybe I was looking for an error page.
Transmitters are harder, since you need oscillating circuits, not to mention more power (especially if the receiver is un-amplified). However, the technology required to create evacuated glass vacuum tubes was pretty much all there since about the mid-late 1700s. What we lacked at the time was knowing how to put it all together.
Remember Morse code and CW transmission? Generating loads of RF is easy -- you need a big stack of batteries, a spark gap, and an antenna. In fact, a spinning sulfur ball and a silk brush could probably generate enough current at high voltage to do the trick. I'm thinking you can even do AM voice without a conventional "amplifying" device, if you aren't concerned about pleasing audiophiles.
I'm almost all in on continued technological progress -- I'm not sure I'd want to live in a collapsed, post-tech civilization. But I've accumulated quite a few hardcopy books about "how stuff works", how to build lab equipment, "amateur science", and the like. I've always been the geek, and I'd have to count on others for basic agricultural and military/survivalist knowledge, but I figure I'd have some value to offer. If nothing else, I'll bet I could build the best stills in the district, and I might be able to give them a leg up on antibiotics and other life-science stuff...
...and if "voting" actually provided a way to override the will of the telecom giants. Believing that constituent voices will override telecom campaign donations and lobbyists is adorable, but not very effective.
These launches aren't that uncommon, but they're visible from a lot of highly-populated areas, and they're bright enough to see even if you've got a lot of light pollution. If you have a good view of the horizon in the proper direction, check it out.
milk in the front of the store costs more than milk in the back, and its tagged and tracked through the payment system differently.
Where in the world are you shopping? At the only store I frequent (Kroger) with front-and-back milk displays, it's all the same brand, same packaging, same barcode. If the barcode is the same, there's no way for the checkout system to detect where it came from and alter the price.
Now, I do notice that the milk they put up front is older (has an earlier expiration date). That just seems like sensible inventory management to me.
FWIW, when I was a student thirty-odd years ago, I hardly ever encountered the plural-noun ("data are") form. I knew it was technically correct, but almost nobody tried to use it. If anything, the plural form seems more common now than it was then.
That's a bit unnerving, given the prevalence of smoking in Russia. Ether's therapeutic index isn't terrible, but when mixed with air and exposed to an ignition source, it turns into a fuel-air bomb, significantly impairing its "non-lethality".
Look, even the summary above makes it clear that "lethality" is usually dose-dependent, and that dosage control is practically impossible in most real-world crowd-control situations. The Snelgrove tragedy is completely unrelated to that issue.
Whether the police are shooting rounds of pepper spray, lead, VX, or candy-canes, if one of them enters your eye socket at high enough velocity, it's unlikely to be "non-lethal". Let's stay focused on the real issue here, the mythology of "non-lethal" chemical incapacitants, and not get distracted by the obvious "don't shoot people in the face with rounds of anything".
What a perfect application for a truck-bed-sided fusion plant.
Actually, scale it up a good bit from that. Cold side for heat-engine power cycle? You're sitting on a giant snowball! Boil off volatiles with the hot side of your exchanger, use some of your power to drive the deuterium separation plant you hauled along, and use the rest to accelerate some of the vapor out the back. It's the next best thing to rendezvousing with an already-filled fuel tank.*
Frankly, when I here "we have unique demands" I ask for clarification an detain gently guid ether to the determination they are not a unique as they think.

I'm sure any Slashdot post invoking both of these political figures will attract only the most calm and well-reasoned discussion.
...so no Battlezone. :( There was ONE GAME that I played obsessively and mastered, and it's not there.
No, wait, there was one raster game I liked, but it didn't make much of a splash in the real world -- Reactor. It's not there, either.
900 games, 850 of which I've never heard of, and the two that I look for aren't there. I want a refund.
I didn't know Rick Deckard was currently working as a NASA spokesman.

Fine, bring on the "redundant" mods.
jeffb (2.718), typing more slowly than Anonymous Cowards since 2008 or so...
If it falls to the ground quickly, it's gravity.
If it drifts to the ground slowly, it's gravity.
If it falls because someone pushes it off a cliff, it's gravity.
If it just slowly slides down a slope without anyone touching it, it's gravity.
So, basically, if downward motion occurs in there somewhere, it's gravity.
I'd really like to see a falsifiable rendering of "gravity". It would make discussion so much easier.
Until the, TEACH THE CONTROVERSY!

That's an interesting point. I think you'd have a hard time demonstrating discrimination against a protected class, though.
For each person, they're displaying a price at which they'll sell to that person.
What part of this is "false"?
Do you also consider frequent-buyer discounts, loyalty programs, and targeted electronic coupons to be "false advertising"?

0.8 kilometer (1/2 mile) is about one kilometer. Claiming more precision ("1/2 mile, or 0.8 kilometer") would actually be misleading.
