    Let's transform energy -- with natural gas - T. Boone Pickens

After the talk, watch for a lively Q&A with TED Curator Chris Anderson. Talk by T. Boone Pickens. Learn more about your ad choices. Visit megaphone.fm/adchoices

    Speech acts: Constative and performative - Colleen Glenney Boggs

    View full lesson: http://ed.ted.com/lessons/speech-acts-constative-and-performative-colleen-glenney-boggs When are words just words, and when do words force action? Linguist J.L. Austin divided words into two categories: constatives (words that describe a situation) and performatives (words that incite action). For instance, is a "No running" sign describing your gait, or are you not running because the sign prohibits it? Colleen Glenney Boggs describes how these categorizations give power to words and, ultimately, to your actions. Lesson by Colleen Glenney Boggs, animation by Lou Webb.
