Pop science - 'Wow it's big!' and 'Wow it's loud!' and 'Wow it's fast!' Been done to death by Robert Llewellyn, Chris Barrie, that bloke off the Fast Show et al
By contrast, I've just heard a hero of pop science, Adam Hart-Davies, on Radio 4 with a special edition of the similarly named 'Engineering Solutions' about CERN and the LHC. Interesting, informed and informative.
And 'Connections', with James Burke, was a monumentally brilliant piece of television.
