Brady Haran has made various series' of short, informative, and entertaining videos, centering around maths and sciences at the University of Nottingham.
I urge everyone to check them out. I stumbled on them recently via YouTube, and have found myself hooked.
Anyways, if you get the urge to revel in your inner nerd, enjoy.
(no, this is not an ad. I am in no way connected to, affiliated with, or even in contact with, the filmmaker or his associates. I'm just a fan.)
