How Scientifically Literate Are You?

Which one?Was it the gases in air question?That is the one that caught out a couple of others I have shown this to.

Even vodka..? Only kiddin. Milk is still in pints. Don't butchers and green grocers still do pounds? Olde swet shops still do old weight measures too. Really? I haven't seen anything but litres for years and years. I think a lot of people are just as comfortable with Kgs.The most common non-metric thing we use is miles (our car speedometers are still in MpH)But - Yes - We use a mixed bag of measurements.

Fracking is a reasonably big deal in the UK. And probably soon to be a bigger deal.Here (so I understand) the term is normally applied to shale gas and the technique used is generally implied to be a new or newly viable development that is relatively untested but potentially bountiful.I don't know if this is accurate. But this is the general impression given by the mainstream UK media.
