Science writer Jennifer Ouellette talks with evolutionary neurobiologist Mark Changizi, about the ultimate foundations underlying why we think, feel and see as we do.
Mark's research focuses on questions such as why we see in color, why we see illusions, why we have forward-facing eyes, why letters are shaped as they are, why the brain is organized as it is, why animals have as many limbs and fingers as they do, and why the dictionary is organized as it is.
They talk about his latest book and work on vision and cognition, plus such crowd-pleasing topics as pruney fingers, complex networks as they relate to organisms and language, the cognitive sicence behind "Eureka!" moments, complexity of writing over human history, scaling principles for city highway networks, and his new science show, Head Games.
Jennifer hosts Virtually Speaking Science on the 2nd Wed of each month. Widely read - Washington Post, Discover, Discovery News, Salon, Nature, Physics Today, Symmetry, Physics World, New Scientist, etc, she maintains a personal science-and-culture blog at Scientific American called Cocktail Party Physics, featuring her avatar altar-ego/evil twin, Jen-Luc Piquant.
