Thanks for this episode. Reminded me of so many things. Twelve years since I studied this stuff for a lot of weeks, relating to Solaris. During those studies I repeatedly wondered 
"So what ?!....the foot bone is connected to the leg bone.".
Never-the-less, sometimes it pays to recognise one's available environment.
You stimulated my brain through a good chunk of dull work.
I would listen to this one again one day.
