With some trepidation (and aware of some of the inaccuracies) I give you the promised link to the talk I gave for the Faraday Institute two weeks ago (this should lead you to the Cambridge University Media website). It was great to see Dan Batovici and Peter Head there (as well as many other friends). And yes, I use the term 'original text'. Most people understand this term better than some of the more recent proposals (intelligibility over technical precision).
