Why symmetry attracts.

Our ideas of what’s beautiful are tied to symmetry. If it looks beautifully symmetrical, it’s beautiful, right? Why? What’s so compelling about faces that are the same on both sides on that nose in the middle?

So to study symmetry we dive into the world of asymmetry – where things are different! And we introduce you to 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 who ended up in a very surprising profession as a result.
