Found it too easy to zone out into a biltz of phrases and names, not certain if I were truly grasping what was being said. Typically finding that a guest is trying to encapsulate something and then Melvin butts in to speed things along.

It is good though, but I find subjects I knew something about already were dealt with in a somewhat obscurantist manner that didn't really impart a high level understanding.

Any favorite episode i should start with?

An episode that really stood out for me when I first heard it was about Imaginary Numbers: http://www.bbc.co.uk/programmes/b00tt6b2
