It would be the best thing ever. Nothing non-perishable would need to be made from scratch more than once, no more resources would need to be depleted, manufacturing and construction would be much, much, much more efficient (who needs an expensive cement mixer when you can just make 1 litre of it and continuously replicate it), and farming would be far, far, far more efficient (grow a hundred plants, put them into a hundred replicators, and you can have as much food as you want).
While that is true, it can be avoided somewhat in some topics by asking questions that are phrased along the lines of "show that the wavelength is 400nm" rather than "find the wavelength". I still prefer long answer, though.
No, we can just keep calculating it further and further until we get enough accuracy to get the correct number of atoms (since there will be an integer number of atoms, the inaccuracy will be lost in the rounding).
New stuff, perhaps not. I don't think that there's anything wrong with selling a copy, without permission, of a film that was produced 40 years ago. Not that that's what most of this is, but it's far from black and white.
I seem to remember a news article about the museum (from an Australian source) stating that they felt that it would not be a worthwhile endeavour in Australia. Which it wouldn't be; something like this would be about as popular over here as a cane toad farm.
As the other poster said, chlorine tablets are probably not such a good idea. You don't put chlorinate water because the chloride kills things, you chlorinate it because it creates hypochlorous acid. Which you probably don't want all over your basement.
If the solar cells are more efficient, then the panels will produce more power, and therefore less will be needed. Also, less space will be needed, less equipment, etc. etc.
Telstra did, but now they have renamed Unlimited to Liberty (and yes, they were previously advertising as Unlimited). That link claims that they changed the name in response to a complaint by the Victorian Fair Trading Commission. I can't think of any others off-hand - most of the ISPs that I know of are somewhat more reputable than claiming unlimited when you either pay extra or are capped.
I don't know why people believe that a few bucks a month guarentees them unlimited bandwidth. If you want guarentees, or you can't sleep at night, pay for commercial service.
The advertising stating that they get unlimited transfer, probably. You can't set up a shop with a sign saying "$5, take as much of whatever you want" and then kick people out for taking too much, so why should it be any different for the internet?
You forgot to add a half hour to go and buy stamps because you haven't actually mailed anything in an envelope for the last eleven months.
How hard is it to walk down to the servo or a post office to buy a stamp? You're already walking down to the letterbox, so it's not that much longer anyway (or at all if you go to the post office).
He might know what every Pokémon card says, but what does he know about any other cards? Pokémon was popular because it was popular (not that that makes complete sense). What makes you think that anything like this will have that level of support?
They might enjoy it, but does it help them to learn more? It sounds doubtful to me. When was the last time that you saw schools trying to use games to teach beyond a five-minute quiz?
Well, I exaggerated a bit, but my point still stands. You can't teach some things without a certain amount of text. Printing it on a card and saying that it's a game will not make a valence shell any easier to understand. You can't learn this sort of thing without the basics, and it is unlikely that a card game can serve this purpose.
Personally, writing about a topic is what has taught me the most. Playing a card game might be fun (for about five minutes, if that), but it's not much of a replacement for a structured text. Is a 60-card collection of trivia really going that useful a supplement? Can you really fit enough useful information onto a card to teach anything useful? IMO, the card game will probably be played solely as a game, if at all, rather than as a learning aid.
Here's how the game works: You command an army of chemical elements, compounds and catalysts -- represented within a 66-card deck (the fire and brimstone card at left is for "Sulfur," for example). Your opponent has his own deck with the same number of cards. Your goal is to battle your competitor and reduce his IQ down to zero. Pit your oxygen card against your opponent's iron card, for example, and you learn that you create rust. Score one for oxygen.

Samar would kick my butt in this game. At least I'd probably learn more about chemistry in an hour of game play than I learned in my high school chemistry class a couple decades ago.
Maybe it could be expanded, but this isn't exactly all there is to chemistry. How can you teach, with a card game, the procedure for a titration? The workings of an atomic absorption spectrometer? Electron configurations? Secondary interactions?
You could, I suppose, write on every ionic compound a paragraph about ionic lattices, and an explanation about dipole-dipole interactions on every polar molecule's card, but how is that different from the textbook?
Perhaps better textbooks would be in order. I'm studying Year 12 Chemistry now, and it could not be considered boring. Those who don't enjoy it, don't enjoy it. Those who do, do. A card game would certainly do no good, other than bore to tears everyone involved. This is just a tacky thing that sounds fun to a 13-year-old, but in reality would never work.
As the other poster said, eV is a unit of energy, not velocity. Velocity is in ms^-1. 1ev ~ 1.6e-19 joules.
Obviously the charge of an electron is constant (in case you get confused eV is a measurement of velocity, not charge). What we use in computers today is the QUANTITY of electrons "flowing" (these days tunnelling may be a better term) through non-conductive layers.
What the article means is that we use the charge of an electron to transmit information at this point, rather than the spin or other properties. While we are not able to change the charge of an electron, we can change the charge of a flow of electrons by modifying the amount of current flowing.
Opposite here in Australia - people over here hardly know what's illegal at any given moment, but using a mobile phone while driving is rare enough that I can't remember any specific instance in which I have seen it happen.
The cost and horrors are still there, but only the opposition is subjected to them. Peace has the benefit of not containing a bloodbath hidden out of sight.
My understanding is that SACE and TER are unrelated, even though both are administrated by SSABSA. You can pass SACE without receiving a TER (pick less than four HESS General subjects). The only issue is that you don't know for sure what it is until after you've finished high school (not that it really matters, since 50% of the mark is from the exam anyway).
I don't really have that many complaints about it, except that some of the Specialist Maths topics probably should be in Studies (I am tired of spending time learning to add vectors in half of my subjects). It's most likely the quality of the teachers that are the biggest factor, really.
SACE only gives you Satisfactory Achievement (10+), Recorded Achievement (3+), and Requirements not met. Anything else, I believe, is the responsibility of the school.
It tells you nothing about how you are going compared to other class members
Neither does my school, but the externally assessed mark is tends to hang at around 13.5 (well, it does for English Studies and Specialist Maths, so one would presume that that's the standard that they write the exams to), which is enough to get a rough idea of how you're doing. Comparing yourself with other class members is useless, anyway, since (at least from my experience) each class tends to hold people of roughly the same ability. You can tell whether you're an idiot or that the test that you got back was just hard, but that's about it.
You misunderstand. When the key transfer happens, they do as follows:
Store the public key.
Send a different public key that corresponds to a private key that is available to them.
Then, when someone tries to send some encrypted data over the network:
Decrypt the data with the private key that corresponds to the false public key that is now in the possession of the sender.
Re-encrypt it with the public key that was supposed to be sent, and send it to the recipient.
PGP depends on the availability of a secure channel either for the key-transfer itself or to verify the fingerprint of the public key. Like any other system, it is vulnerable to man-in-the-middle attacks.

Can't the pharmacist replace it with a generic? Or is that not allowed over your way?

Maybe so, but what happens when the sun explodes holds no relation to what happens when it implodes.

I'd hardly call this reverse engineering. The unclassified document was made so by simply removing the scale from a graph.
This is even worse than declassifying documents by putting a box on top of text in a PDF. How can people be so stupid?

I suspect that they are intended to have sunlight focused onto them, rather than just put out into the sunlight.

Actually, unused memory is disk cache, and far from wasted memory.

I've heard good things about IB, however I don't think it's common (or used anywhere?) in public schools, which take something like 70% of students. Fortunately, I don't think either have anything truly horrifying, whether because it is impossible to get a question wrong, or because the exam needs to check whether someone knows how to factorise a quadratic..
