Horizon: The President's Guide to Science
mod
It's a program which talks about scientific principles in laymans terms, focussing on the ones that might prove pivotal for a US president to know about. It doesn't go into great detail at any point, but it was a great watch for me. Layman's explanations by specialists, smothered in nice visuals and sound design.
