Each week, I will pick a TED talk to share with PLSD.  This talk could be about teaching and learning or about technology or about leadership or just something fun.  TED is a world of spreading ideas and thinking outside of the box.  TED is a world that there is no right or wrong, only what if.  TED opens the door for innovation, creativity and the future.

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.

This week’s TED Talk is about the most powerful ideas of 2014? Watch our 8-minute highlight reel of the Year in Ideas.Explore a fun, interactive playlist of the TED Talks of the year at http://yearinideas.ted.com/2014/
