In this five-minute clip from The BBC's The Pleasure Of Finding Things Out, physicist Richard Feynman talks about his father, and how Feynman was taught by his father, the Encyclopedia Britannica, and good old-fashioned experimentation. It's a nice look into the origins of Feynman's thought processes, and how he attempted to pass them on to his own children.

Sample quote: "[My father] knew the difference between knowing the name of something, and knowing something."

My favorite moment starts around 4:20, when Feynman describes how his own son has a "word bag" that one day ran out of the word "cat." Adorable.
