    The reason they're not thinking that is, probably, that there has as yet been no evidence that there were humans in mainland Greece anything like that early. The earliest known sign of human habitation in Europe is only ca. 40k years old.

          There's too much speculation. "No evidence of human habitation" doesn't mean there absolutely were no humans, only that we haven't found settlements. I for one would be much more comfortable with an undiscovered Greek sea-faring civilization engaging in island-hopping trade among islands within sight of each other than a mysterious African tribe that suddenly invented the boat to colonize the island they had somehow heard about "over the horizon". Occam's razor, and all that. Obviously if a single discovery can completely "revolutionize" archaeological thought like this, then the "facts" and "evidence" are fairly shaky at best and I wouldn't back a claim that "Greece was uninhabited" is set in stone.

          No I'm more of a results oriented person who believes that dwelling on the past is not constructive to future progress. The past exists to be learned from, not lived in. My own past is full of very real nightmares and ghosts, things have happened to me that make everyone who finds out gasp in amazement. The key to survival is getting over it, not using it as an excuse for a "handicap". A person who has so called "math anxiety" and is determined enough can get past it. Or they can wallow in it and use it as an excuse to lead mediocre lives following the path of least resistance. Life is full of choices. Perhaps I am educating YOU.

    Just an anecdote but oddly enough most of the people I know that have gone on to high level math (>>Calc 3) tend not to be terribly good at doing basic math in their heads.

          Heh, I'm just the opposite. I'm very good at mental arithmetic, and I can multiply 4 digit numbers in my head usually faster than someone who reaches for a calculator, but I absolutely suck at math - especially trig (Calculus not so much). However I chalk it up to carelessness because I understand the concepts fine but I keep dropping or changing a sign here and there when I'm working out a problem. Which is why I went into a field in the biological sciences. Pretty much all the numbers are positive! Now my most complicated "formula" is "ok the kid weighs 8kg and the dose is 40mg/kg so 320mg per day divided by 3 is (rounding and adjusting up to the next dose easiest to dispense) 120mg 3 times a day...

    The bottom line is if you can't count, you can't count. AND practice makes perfect. Oh and guess what - doing something over and over also reduces anxiety. Hey, maybe those people are "anxious" about math because they're the ones that never did their math homework! Maybe doing math homework and doing the "extra credit" problems and oh I will go all out here - doing the EVEN numbered problems even when your teacher only assigned the ODD numbered problems, and WITHOUT looking at the answers in the back of the book, help build confidence and reduce anxiety.

    While your beer/soda anecdotes might be quite entertaining, the poster I was responding to compared the conductivity of water to the conductivity of air.

    Now since this is a site for nerds, we don't need to resort to anecdotes to make points. There exists an SI unit for conductivity called the Siemens per meter (S/m).

    While it's true that clean fresh water has a LOW conductivity (around 5 x 10^-2 to 5x10^6 (your deionized water) S/m), and while this is less than sea water which comes in at 5 S/m, and while I agree that this is several orders of magnitude less than say aluminum at roughly 40 S/m, air has a conductivity of 3 x 10^-15 S/m which is QUITE a difference. In fact it's 9 orders of magnitude less than the "purest" most "non conducting" water, compared to from aluminum to fresh water being only 4 orders of magnitude.

    I don't concentrate on deionized water because first you won't find it outside of a lab and secondly even in a lab it won't stay deionized for much more than an hour once you expose it to air.

    However let's be more practical. Again, feel free to prove your theory that water is not a conductor by standing in a puddle barefoot and electrocuting yourself. Remember to ensure that your last thought be "I'll be ok, water doesn't conduct electricity". And please name me as the beneficiary of your life insurance policy before you do this. Water is a BAD conductor, but it is a conductor nonetheless and you may feel free to plunge your electronics in it. However I shall pass.

    Pure or distilled water can't hurt an electric device any more than air could.

          Good luck finding "pure" water anywhere on PLANET EARTH. I am fed up with this internet myth. The people who go around claiming that "pure" water doesn't conduct electricity don't remember that water SELF IONIZES to H+ and OH-. Which is why "pure" water has a pH of roughly 7. Oh what does pH mean again? It's the negative log base 10 of the molar concentration of Hydrogen IONS. So in every mole of "pure" water, you will actually have 10-7 moles of hydrogen ions and 10-7 moles of hydroxide ions and GUESS WHAT? They are charged and conduct electricity!

          The fact that water is not a "good" conductor can only fool idiots into thinking that it's an INSULATOR (ie "pure water doesn't conduct electricity"). For all these idiots I invite you to use water immersion cooling methods for your computers, because after all who wants to deal with all that icky mineral oil... or better still, stand in a puddle of "pure water" on a "clean" conducting surface, and put your fingers in a 240V socket.

    Pure or distilled water can't hurt an electric device any more than air could.

          Yes keep thinking that and keep wondering why your electric devices keep frying when they shouldn't be, instead of learning some damned chemistry.

    And that's just a single game and these are huge publishers. Selling 82 million copies between all their games isn't as large amount as you think.

          But wait - you forgot to apply the 15% metric to modern warfare 2. Since 85% of sales are lost to piracy, Modern Warfare "should" have sold $13.3 billion dollars, right? Or do people only pirate Ubisoft games?

          So let's see, Modern Warfare 2 should have sold not 15 million copies but 100 million copies, right? Wait, since Modern Warfare 2 doesn't use Ubisoft's draconian DRM but plain old secuROM AND it was available on the internet BEFORE the launch, this must mean that even MORE "sales were lost", right? Perhaps the real sales figure should have been closer to 500 million? 1 billion copies? Maybe everyone on the planet was going to buy it?

          The truth is that games go stale very quickly on the shelf. Within a year, prices get slashed. After a couple years, you can usually pick them up for under $10. After 5 years or so, you have to bundle them with other software to move them at all. So I encourage you to hold the price constant while you multiply it by the "number of copies sold" and invent imaginary numbers to try to justify your claim. But just like Hollywood movies - if you didn't make the money in the first few weeks, you're probably not going to make much more. The income/time curve looks like 1/x. I assure you "Modern Warfare 2" is not going to make ANOTHER billion over its lifetime. Everyone who was desperate for a copy already has one, and now it's up to impulse sales.

          Plus we were talking about PC sales (which is where DRM is required and "piracy" happens), but the Modern Warfare figure is TOTAL sales on all platforms. Very much an apples:oranges comparison.
