New in October 2017

Loose ends from September and also from so long ago that I can’t say I know how I came to revisit them, let alone why I didn’t finish them first time round. Well, on that last point the answer may simply be that, as would be known to anyone who works at understanding something that’s large and complex and of moderately wide interest, there’s no end of stuff to look into and write up. And, of course, I don’t always have either as long an attention span as I’d like or the resources to keep plugging away!
