Thank you, Ian. That was a much better, more helpful answer than I ever got on that old thread - "Beginning of entropy" quite an apprehensible concept.

As to appropriateness of asking on this forum ~~ tho peopled by folkies, many of them have other interests & qualifications too. Why, I was even a theatre critic too, way back in the day... So ask me about Æschylus or Noel Coward or Pirandello or Corneille or Beaumont·&·Fletcher, why dontcha, and see how well I can waffle...
