TED 2014 is held in Vancouver, Canada. Today (March 19th), TED post the video "Chris Hadfield: What I learned from going blind in space" free online for all to watch. Free is a pretty good price comparing to the US$7,500 to attend in-person in 2014. You can "apply" to attend TED 2015 now for US$8,500 which seems a lot for 5 days! Anyway, hope you enjoy Chris Hadfield's TED Talk.
