I love TED talks.......
TED is a nonprofit devoted to spreading ideas, usually in the form of
short, powerful talks (18 minutes or less). TED began in 1984 as a
conference where Technology, Entertainment and Design converged, and
today covers almost all topics — from science to business to global
issues — in more than 100 languages. Meanwhile, independently run TEDx
events help share ideas in communities around the world.
