Morally it made a big difference, but from a military point of view it was pretty much a full surrender. Formally it made a difference, as this made soldiers wearing Norwegian uniforms lawful combatants. If they were caught during missions in occupied territories, they should be awarded POW rather than saboteur status, according to the Geneva convention. Of course, that didn't always happen in reality, some of them were summarily executed.
I thought you were being sarcastic in a different way for a second, because so many people still bring that junk through checkpoints, slowing us all down. What use could anyone possibly have for an extra laptop battery on a five-hour flight...?
There was an article a week or so back describing some place printing ballots on demand. What if paper ballots were printed on demand, but the people printing them are the voters? A machine could be hooked up to print a ballot when a voter presses the correct buttons, and would only print out one ballot per voter. The ballots themselves would also have a barcode on them with a code certifying which machine printed them. The printers would count how many ballots were printed, and if that number doesn't match the number counted, that'd signify a problem -- either the machines were tampered with, or the physical ballots. Wouldn't this violate voter privacy? If the only paper ballot you have matches the actual vote case, you could take a snapshot of it with your cellphone and show to the guys who paid for your vote. A major point with secret ballots is that you do not have a paper trail, so you can lie to anyone instructing you to vote for a certain party.
You would need to have the machine print arbitrary ballots, which would of course cause problems if there is a paper recount after the machine count failed, and you managed to put the wrong ballot in the envelope... the whole thing looks a little difficult to me.
Tetraethyl Lead (TEL) was never used in diesel. It's used as an additive used in gasoline to make it easier to depress the piston in the cylinders without accidentally igniting it. This is only necessary for spark plug engines.
Interesting, as I think his books are much clearer and to the point than I'm used to in physics/engineering. Perhaps he's just better with the written word than in front of the blackboard? Personally I'd recommend his books to anyone (with three or more years of college physics) who wants to know more about flight. His book on computational fluid dynamics (CFD) is particularly lucid, imo.
His strength is that he starts each topic with a brief talk about its application, as a motivator. You are never left wondering "what's the point in this?". He also is very good at choosing the appropriate mathematical depth -- neither bogging you down with equation nor leaving out important steps.
I should note that I have a theoretical fluid dynamics background, rather than engineering, which may influence how I read him.
HE 1523-0901 is as you imply a very old star, but not a "first", since the first star would not have heavy elements. What the article says (for some reason I can only access the abstract, something's rotten over at ApJ) is that HE 1523-0901 was contaminated with mostly r-process elements.
Frebel &al's case is that since r-process element decay more quickly than those produced in by the s-process, this old star could only have been exposed to a few supernovae. And supernovae were very common back in those days since the high hydrogen concentration produced many heavy stars. The conclusion is thus that it formed just at the same time as the first supernovae, and those took place only a few million years after the first stars formed.
The r and s-processes are the two ways in which heavy elements are produced in core collapse supernovae (type 1b, 1c and 2).
Please Mr. Slashdot, stick to the computer stuff! There is nothing wrong (or even inaccurate) in the cited articles. The structure of the solar magnetic field is complex, and these simulations are probably going to help a lot in understanding them. Personally, I'm looking forward to reading their article ( http://adsabs.harvard.edu/abs/2007astro.ph..2604H ).

Actually Norway never surrendered. They moved their administration to London.
Good thing you only need 12 ores to complete the quest :/

A simple substitution cipher has a keyspace of 26! ~= 1.7e26. It is still broken in seconds just by looking at it :)
