I first came across complex numbers in the early 1970s, and the only symbol I ever saw used to mark the imaginary component was i. It might have...

Platinum and palladium come close, though. If a car needs a replacement catalytic converter, it's because the old one wore out or got damaged --...
In June 2008, rhodium hit $10050 per ounce. (No, I did not type an extra digit by mistake.) In November 2008, rhodium hit $1000 per ounce. (No, I...
Huh. I didn't know acetone required that. Makes sense, I suppose. Fortunately it doesn't look like something that would affect metal or toning,...
I haven't looked closely, but I didn't think you could get 100% pure acetone there, only "nail polish remover" with scents and whatnot added...
I'd have to say Shield Cent, but only because they're saddled with the zinc reverse-galvanic-protection composition. I actually like the shield...
OMG -- The Sticker King!!! (29957blue, aka "Zack's", used to post photos of coins in 2x2s covered with stickers. The one I remember is "Less than...

So, will you be taking photo gear? I've got a 100-400L that produces an image of the lunar disc maybe 800 pixels wide on my sensor; trying to...
Taking them even further from their "original condition". ;) Seriously, I think the "removing foreign material" bit is necessary and sufficient....
Closer, but "contamination" is overly specific, I think. I still don't think "original state" belongs. The carrot was covered with dirt from the...
As for my own definition, I can't do any better than "removing foreign or undesired material from an item."
I'd argue that that's not a good definition of "cleaning", but it is an excellent example of "begging the question". What does "original state"...
Y'know, it's funny -- Abe's face gets smoother with age, but not mine...
Never mind that. Think how many rolls of Wheats you could get with the money you spend on cigs!
So, if that's the case, I think the solution's perfectly clear: ask them to send you their card reader! You run the transaction, send it back to...
Separate names with a comma.
