TED is a platform for ideas worth spreading. Started in 1984 as a conference where technology, entertainment and design converged, TED today shares ideas from a broad spectrum — from science to business to global issues — in more than 100 languages. Meanwhile, independent TEDx events help share ideas in communities around the world. https://www.ted.com/talks/jay_walker_on_the_world_s_english_mania (do notice the pronunciation of the word "mania") http://www.ted.com/playlists/117/words_words_words (hilarious) https://www.ted.com/talks/mark_pagel_how_language_transformed_humanity (the power of language) Subtitles and transcripts are also available for all the speeches.
