The TED Talks (Technology, Entertainment, and Design) have a reputation for being quite fascinating, though perhaps a bit disconnected from every day life. For example, David Gallo’s talk about astonishing creatures living beneath the seas. They’re all fascinating (particularly the octipus at the end), but how much relevance does it have to every day life?
But then we have other talks, such as this one by investor Yossi Vardi who talks about how important it is to prevent not just global warming, but local warming too.
