How do our eyes make sense of the world?

An untutored brain — or a computer — could go nuts with the visual input we process every moment, like trying to sort a swimming pool full of broken stained glass.

McGreggor will be among the speakers Oct. 17 at the TEDxPeachtree conference at the Buckhead Theatre, a day-long program organized around the theme “Illuminate.”

Among 12 others addressing the conference will be Chantelle Rytter, organizer of the Atlanta Beltline Lantern Parade, and Genna Duberstein, lead multimedia producer for heliophysics at NASA’s Goddard Space Flight Center.
