Our ideas of what’s beautiful are tied to symmetry. Symmetry attracts. Why? What’s so compelling about faces that are the same on both sides of that nose in the middle?  To study symmetry we dive into the world of asymmetry – where things are different. Dessa talks with a professor who studies right- and left-handedness, a graphic designer who explains the appeal of a bit of asymmetry and a woman who grew up with a distinctly asymmetrical face – and ended up in a very surprising profession as a result.
