Mostly right, but it's important to note that AC voltages are usually listed as RMS values. When you are worried about a voltage getting through your skin, however, you are mostly worried about peak-to-peak voltage. Since the RMS voltage of a pure sine wave is approximately.707 of the peak voltage, there is the potential to be misled. Consider that 50VDC is really 50V whereas 50VAC (RMS, which is often reported) peaks at over 70V. If that extra 20V is enough to overcome your skin's resistance, it may burn your skin which will reduce your overall resistance considerably (human internals are mostly saline, after all).
From wikipedia: An average bolt of negative lightning carries a current of 30-to-50 kiloamperes(kA), although some bolts can be up to 120kA, and transfers a charge of 5 coulombs and 500 megajoules (enough to light a 100 watt light bulb for 2 months).
So 500 megajoules in a fraction of a second? We're definitely talking jigga watts.
Those references sound like they are saying that some 3d curvatures can be DETECTED by 2d beings, not that a 2d surface can be curved without occupying a 3rd dimension. This may just be semantics in the way you interpret the anomolies introduced by (for instance) flattening a 3d sphere into a 2d plane. In other words, a 2d being inhabiting the surface of a sphere could detect the curvature by attempting to circumambulate a certain triangles (making the turns add up to 180 degrees) but finding that he did not arrive where he expected to. This could be interpreted by the 2d being as his 2d plane being warped, or as existing in a 3d dimension.
If this interpretation has an error, please point it out as my background does not allow me to completely follow the reference provided.
Whoah, this one's news to me. Do you have any references for this? Just a keyword for this phenomena would help, as "curved surface not needing a higher dimension" doesn't really work in google:)
Dispite the redundancy in there, I think that's a great idea! If you keep complaining about the damned thing after you've disabled it, he won't even know it's broken.
Despite the spelling error in there, you're right about the redundancy!
Yeah, I guess this wasn't an explosion: http://youtube.com/watch?v=FFxx1o84dj4
Jet fuel may not technically be an explosive, but igniting a plane full of it over an airport would be as bad or worse than a conventional explosive.
On a more serious note, if you are shooting a laser at a device that contains explosives within it, you need much less power to detonate it (or at least seriously damage its detonation mechanism) than to shoot down an airliner.
Explosives, you say... you mean like jet fuel? It's not just for breakfast anymore.
I imagine you were modded troll because of the glaring inconsistencies in your post. For instance, you say that you were carded buying epoxy at Walmart when you could get it at any supermarket without the hassle. The obvious question here is why you didn't do elsewhere to begin with -- especially since by purchasing at Walmart, you are supporting an establishment that you deride for participating in censorship. Either that, or as usual, the mods have been sniffing the aforementioned glue.
Anyways, to answer your question, no I haven't been to Walmart. I, too, find their practices questionable and I'd rather not give them my business. That doesn't change the fact that the epoxy example isn't analogous to the CD issue for the exact reason you stated at the end of your post: they don't have the power to change the nature of epoxy, but they do have the power to change the CDs. Given then choice between a product that they have to card for and one they don't, it's a no-brainer to go with the "kid-friendly" version. Now, whether their primary motivation is "corporate responsibility" or "corporate profitability" is something that we could argue endlessly. It doesn't change the fact that carding for CDs is a pain in the ass that I'm sure they would like to do without. I'm sure that if they could get a non-sniffable epoxy, they would sell that instead.
Not only that, but they also require you to build a separate door, to which only the police have a key, with money from your own pocket. But don't worry, cause the police will only use that key when they have a warrant. Or when you are out of town and they need a good place to have a party.
He didn't say that it was hard to KNOW WHEN to card. I think his point was that the actual carding would be on a much larger scale with CDs. Walmart is the kind of place that spends a lot of money shaving a few seconds off their credit card authorizations. They do NOT want to add even a minute to any transaction if they don't have to. Plus, you know how people get pissy if they are over 21 but get carded for booze? Imagine all the irate teenagers who get carded for something even sillier. They probably figure it's not worth the hassle.
Wait, what is this "minus expenses" parenthetical remark? Expenses are the law firm's bread and butter. Expenses include but are not limited to: Attorney salaries, assistant salaries, Managing Partner's Dog's salaries, catering services, car services, car washes, travel expenses, strip club outings, and energy efficient lightbulb surcharge.
Are you talking to me? I think you're talking to me. In this situation, I was a lurker. Two other parties were arguing about X and Y and nobody was giving Z, which was my complaint. I didn't need feedback.
Yeah, except it pisses off people like me who read "you're wrong, no you're wrong, no you're wrong" and nobody ever puts up specifics and then I learn nothing. And I'm so tired from reading your useless dialogue that I don't have the energy to look it up myself! And I missed my nap!
Dude, you are smoking some serious crack. I'm not saying Carnegie was a saint, but there are inconsistencies in your argument. If Carnegie's strongarming kept the steel mills running at lower cost, that wouldn't CRIPPLE industrial growth, it would SPUR growth at the expense of the workers.
I don't know anyone who thinks unions are corporate puppets, since they DO have an enormous amount of power here in the US. You know how the goverment is always stepping into union negotiations to keep things like airplanes and education services running? If unions were puppets, there would be none of that nonsense.
No matter what you think of the man, it's hard to disagree that he will be remembered long into the future for the good, and most will overlook the bad. I'm not saying it's right, but that's certainly the way it's going to be.

Can't you just cite the treaty itself?
You know, it's like 16 different shades of gray.

Is a conclussion like a concussion brought on by the conclusion obtained through the use of a clue-stick?

They can do whatever they want with their site. I just don't think they can do whatever they want with my wallet.
hehehe, you said analize....

Now that's a feature I'd like to see in the next version. For when your porn is just too darn small!

See, THIS is the one that should have been modded funny!
Of course this is better, but it's not always possible. I realize you weren't promoting this idea yourself, but just the idea makes me a little mad.
I prefer "whimsical"
