That was funny, when I read the title in my recommendations I thought "Exactly, why is that!" and then approximately 1.5 seconds later the explanation was in my mind. Thanks Cosmology Today for making me smile.

I often leave Feynman lectures on when I go to bed. it helps calm my mind and ensures a good night's kip.... Unless my ears prick up cos an interesting problem has arisen, then I have to get up until a reasonable conclusion has been reached. R.I.P Dr F still teaching in 2016.
