After his talk at TEDGlobal 2009, David Deutsch answered questions from TED Curator Chris Anderson. It was a short, but fascinating Q&A, so we thought we’d share it here on the TED Blog! http://video.ted.com/assets/player/swf/EmbedPlayer.swfContinue reading
Why you should listen
David Deutsch is a physicist and author who is, as he puts it, "interested in anything fundamental." He discovered the first quantum algorithm and is the codiscoverer, with Richard Jozsa, of the first quantum algorithm that could solve certain problems exponentially faster than anything available to classical computer science.
Deutsch has proposed constructor theory, which postulates that all laws of nature can be expressed in terms of whether a task is possible or impossible -- a theory that extends not only to computation, but also into everything that exists. He is a proponent of the multiverse interpretation of quantum mechanics, which has the startling implication that every physically possible event exists somewhere within an infinite fabric of co-existing universes.
What others say
“Amazingly enough, it is Deutsch's idea -- one he has harbored since childhood, he says -- to truly understand "everything" that is known. Even more amazing is how close he seems to have come and how well he explains it to the rest of us.” — The San Jose Mercury News

Unedited running notes from TEDGlobal 2009. Our ancestors wondered what stars are. Humans have always yearned to know more — it is a survival instinct. “How can I be warmer, cooler, safer, in less pain?” Prehistoric cave artists may have wished to draw better. But although they wished for more knowledge, for progress, they failed. […]Continue reading
