I have some postmodern tendencies. One of them is that I like to see the substructure of things. I like to see how things are made, whether they are skyscrapers or salt mines or even speeches. Here is a gem, a “mini-documentary” of two 2010 TED speakers: the now famous Sir Ken Robinson and the comparatively little-known, Raghava KK. I especially enjoyed the end of the video, the look on the young man’s face when he heard from his mother.
