As a physicist, Max Tegmark sees people as "food, rearranged." That makes his answer to complicated questions like "What is consciousness?" simple: It's just math. Why? Because it's the patterns, not the particles, that matter. Learn more about Max Tegmark at space.mit.edu/home/tegmark/mathematical.html and TEDxCambridge at www.tedxcambridge.com. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.
