Mark Changizi: Alien Vision Revolution

alien vision eye changiziThis could be interesting: RPI cognitive scientist Mark Changizi will be giving a talk about human vision Wednesday evening. From the blurb:

Why do humans see in color? Why do we have eyes on the front of our heads, like cats, rather than on the sides, like horses? And how is it that we find it so easy to read when written language did not exist until a few thousand years ago--a virtual millisecond in evolutionary time? These are just a few of the riddles theoretical neurobiologist Mark Changizi explores in his talk on Alien Vision Revolution. Searching for the design principles behind color vision, binocularity, motion, and object recognition, Changizi suggests what they say about human nature and the circumstances in which it was formed. He also uses those principles to extrapolate how extraterrestrial beings would be likely to see--probably the same sorts of writing but not the same colors, and not with eyes that face forward.

Changizi recently published a book last year called The Vision Revolution, about recent scientific insights into human vision. Commented Melinda Wenner for Scientific American MIND: "One thing is certain: The Vision Revolution will make you wonder the next time you notice someone blush, catch a ball or finish reading a magazine page."

Changizi's talk is at 7 pm at EMPAC. It's free and open to the public.

Definitely needs a mural. Another spot that is begging for one is the Delaware Ave Price Chopper in Albany. The side along Elm St is a huge gray wall that takes up most of the block!
