How Scientifically Literate Are You?

Hi petrophysics1I'm currently involved (government initiative) in setting up guidelines for exploration by means of 'fracturing' and extraction of shale gas in the central Karoo basin (the gas is there, the exploration for resources by 'fracking' and the extraction method is controversial).It's going to be exciting. Lot's of challenges from everywhere, also from the greenies (even though I'm a soft greenie).I've never heard of a word called 'frac', previously, though. Maybe it's an American word not used anywhere else? But, you've added to my vocab. As long as you learn the word 'braai' when you do barbeques on our extracted, fracked shale gas here!!Never too old to learn, I guess. Just don't expect everyone in the rest of the English speaking world to understand every word of your or my English. It differs way too much.Edited by Pressie, : Changed a lot.
