There's something charmingly apocalyptic about a gold vault.

Martin isn't autistic, dumbo. He's just a chemist and they're excited about chemicals.

I would suggest the SCIENCE HAIR! tag though.
ALL chemists are autistic, Fever. You could split the difference and call him a "better autistic", but a posh job title and a dgree from Cambridge can't hide the truth.
i like it, done and done

Just because he's a nerd, doesn't make him autistic. He has a wife, colleagues, personality, communication. He isn't autistic. Autistic would be withdrawn and unable to communicate except on a very personal level, even on the lowest spectrum.
If you watch in HD you can see it's the beginning stages of Parkinson's. I liked the plutonium video too but it would have been better if They let him into the plutonium vault.
Stop killing the joke, Jet Bin, you autistic weirdo.

I was pretty startled by the statement about the total amount of gold ever mined. I knew it was rare, but 60mx60m doesn't seem nearly enough to account for the entirety of history. I'm guessing the number is only since they've been keeping records or something.
I can't find any sources that show their work, or even tell you who DID the work, if indeed any work was even done. Wikipedia, for example, cites an industry website that makes no effort to back up it's numbers and, worse, actually contradicts the numbers that Wikipedia claims to have got from it. The actual estimates vary WILDY, and range from about 60k tonnes to 190k metric tonnes, with most hovering between 140k and 160k. Virtually everyone agrees that this is the total amount of gold EVER mined (that does include estimates from prerecorded history) and that it can't exceed 190k or so. Modern mining is also much more productive than ancient mining was, as Mr Purple Cat suggests; more than half of our current global gold supply has been mined within the past fifty years, and pro-industry organizations suggest that the planet's reserves of mineable gold will be exhausted within the next couple decades, unless we start extracting gold from seawater or something.
There is a cube in Republic, WA that is about 4 feet on a side that represents nearly 50 years of mining there, and what the haul of 2 million ounces of gold would look like cast in one solid piece. It doesn't look like much-
Also you can't get gold from any old seawater, but you can get it from deep ocean vents, those 'black smokers' that are real deep and full of life. That is how all gold has formed, it comes from superheated solutions flowing from the mantle that collected in fractures and pores in various geology, leaving the veins and massive porphyry deposits we mine today.
Those chunky rock formations hat grow around those black smoker vents are loaded with gold, copper etc. In fact in places like Iceland that can exploit that kind of hot water for geothermal heat find their power plant pipes get clogged with mineral deposits, only instead of calcium and crap you might find in your house pipes, its a decent concentration of gold.

Very little of the gold initially mined has has been buried by its owners (or with them) and forgotten. It nearly all still around as bullion, jewelry, dental work, or electronics electroplating.
Also, the MacArthur-Forrest cyanide process first applied to gold ores in 1887 permitted gold to be leached from low-grade ores without visible flecks, and is responsible for the great majority of the above ground gold today.
See http://www.goldsheetlinks.com/autotal.gif for a graph of cumulative gold production. 90% of all gold ever produced has been mined in the last 150 years.
Fucking gold mines, how do they work?
