How they mine and refine pure gold.
I thought it was very interesting.

I read a little while ago in "A Short History of Nearly Everything" that the most likely event (theoretically) that could've created the element, gold as we know it. Is the direct collision ograterwo neutron stars. Apparantly that's the only thing that could generate the required heat.

Since I read that, I find gold much more interesting. I mean, we can create diamonds in a lab now but we might never, ever, ever find a way to create gold.

(incidently, this is a great way to make your wife think that she'd rather have gold than diamonds.)

They're mining 6ppm ore and probably creating thousands of grams of pollution for every gram of gold they produce... This, and all other sources of pollution, should be taxed heavily.

This clip is actually from the original Canadian version of the show. It's my understanding that the primary difference with other localizations is that different narrators are used.

this lady's voice is extremely irritating to me.
what the hell is gould?
i suppose it could be the past tense of "goul"
a synonym of goul is spirit
past tense of spirit would be spirited
spirited synonym is lively

How it's Made: Lively.

Actually, and incredibly, nearly all elements formed inside gigantic stars billions of years ago. The sun, whose massive internal pressure fuses 700 million tons of hydrogen into 695 million tons of helium every single second(the remaining 5 million tons are released as pure energy) isnt powerful enough to generate any other elements, they all formed in absolute massive explosions and collisions in the early universe.

When Carl Sagan said that we are all made of star-stuff, he wasn't being metaphorical, he was literally right.
