Who says you can't have both? With traditional medicine, they're called side effects. Perhaps chemotherapy qualifies too (attack everything, hope the cancer cells die first).
Yes, that'll teach them! They're going to weep all the way from the courthouse to their next case, with their shiny new precedent as their only consolation.
Heh, thanks. By "annoying" I meant that the missing "www" sometimes takes you to a different site, but I can see clearly now that I need more quality sleep:)
Not necessarily. Ever said "when I grow up I wanna..." without a clue as to what it would take? You still have that option as a grownup, with perhaps a better chance of making it since you make your own decisions:)
Isn't this a href= thing fun? I can go on all day. I am, however, saddened, that you call this "some mistakes".
Not to bait flames: And here you are as well as sp3d2orbit, typing this for all to see without (much) fear that the (Dutch? American?) gov't will knock on your door for disturbing the peace of the population.
Isn't this free speech thing fun, even if spotty? I guess a Chinese citizen with average Internet skills couldn't get away with that for long, much less if he can't even fully trust that "secure connection" icon in his browser.
Okay, so it's all about needing a *very* high current to align the domains, i.e. high coercivity (if such concept applies to ceramics). Thank you lots:)
And BTW, that magnetic spike surely creates an EM pulse that could really ruin your day if you stand nearby wearing a pacemaker.
Judging by the stories I've read here and there, a straight look in the eye, asking more than twice and their gut feelings could actually work better than the current system.:)
Sorry for replying twice, but I forgot to point out this: there are two possible applications for strong magnetic fields in a HDD factory: one is to "bake" those nasty rare-earth magnets (I haven't the faintest idea how they're made), and that would surely be a DC field (harmless), and the other would be an AC field to demagnetize any other components before assembly, including the blank platters. The latter is the one that can jam a pacemaker, since the induced current in a decent conductor can get really high even at low frequencies.
Sorry, a strong magnet does not an EMF field make. EMFs are about varying fields - an oscillating magnetic field produces an (also oscillating) electric field, and viceversa.
The current line of reasoning is more or less: the RF energy sure does not disrupt DNA since no matter how many quanta are hitting you, they are too weak to break the bonds involved; the remaining concern is whether the heat produced in the tissue when it absorbs the radiation can produce any harm over the years. The preliminary consensus so far is "unlikely", but you gotta be sure...
“Our system can run nearly perpetually if periodically exposed to reasonable lighting conditions, even indoors [...] Its only limiting factor is battery wear-out, but the battery would last many years.”
By the time the battery wears out, you have gotten a few years of data; then you toss away the tiny thing.
Even when it's 100% reflective? (Yes, I know it's impossible.)
Pure aluminium can reflect maybe 97% in far IR, so you need to supply 30+ times the energy needed to deliver the same energy to black body and destroy it.
Come to think of it, in practice the aluminium will be coated to prevent degradation (I did a cursory search and couldn't find any info on what is used), but this coating would absorb some radiation and ideally fizzle away. Then you'd have the spanking-new aluminium exposed.
That's right- in the end the high reflectivity just means you need a bigger laser. Also, aluminium doesn't stay pure for long when exposed to the air - as we all know, it becomes dull gray Al2O3.
Still, they seem to need such a big laser for an effective hit, but surely they didn't aim for a compact design at this stage.
The laser's mirrors are under special conditions, certainly not exposed to good-old-O2. As for tracking, you have a big shining fireball during the boost and ascent phases - quoth the fine article:
the modified 747-400F aircraft took off from Edwards Air Force Base and used its infrared sensors to find a target missile launched from San Nicolas Island, California.
It's not so much about being "mirror-like" (polished), but rather about being "white" (reflective). The thing is, nothing reflects 100% of the incoming light - even the reflectivity of pure alumin[i]um's is slightly above 90% for visible light, dips to 85% around 850 nm (near IR), and bounces back to perhaps 97% in the micrometer range (which is what some big lasers give out if I'm not mistaken).
Still, 97% is a lot of wasted energy, and thus the need for high energies and huge lasers on ginormous shar^H^H^H^H planes. But perhaps light is perhaps the only thing that can reliably hit a speeding missile.
I'm not sure what level of development they expect for a possibility of $3k, but it will probably end up being bored flash developers and computer-precocious grammar school classes that compete.
Thanks for the correction - it was not entirely clear to me with all the buzzwords the measly $3k led me to think that it was for the kids (their families).
Now come to think of it, how on earth is a videogame going to make kids exercise and eat healthier? I remember a silly flash game on Dilbert.com where you caught fruit and other healthy morsels and dodged pizza, burritos, etc. as they fell down the screen.

Dipole antennas in this case are installed vertically. Think of it this way: the doughnut is meant to cover you, the customer.

It's www.paint.net. Annoying.
Not bloody likely.
Likely bloody. Very bloody.

/me reads his own post and crawls under a stair before the booing starts.
Try standing out in front of Lowe's or Home Depot on a Saturday morning. It seems to work for others
Or the Chinese Embassy ;)

On top of that, the frequency of said oscillation not only determines the depth to which it penetrates the tissue, but is also vital to any biological effects, and that's where the argument about nonionizing radiation comes.
The current line of reasoning is more or less: the RF energy sure does not disrupt DNA since no matter how many quanta are hitting you, they are too weak to break the bonds involved; the remaining concern is whether the heat produced in the tissue when it absorbs the radiation can produce any harm over the years.

Then you're not an Apple fanboi; you just really like the way they make (most of) their products.
He's just accepting the inevitable and accepting his new artiste overlord. Have you?

Insightful? I think this is a joke
Insight is often at the root of (fine) humour.
