From hair parts to the origin of the universe, how symmetry shapes our existence.

This hour of Radiolab, Jad and Robert set out in search of order and balance in the world around us, and ask how symmetry shapes our very existence -- from the origins of the universe, to what we see when we look in the mirror.

***Are You My Brain Double?

***Mirror, Mirror

***Nothing's the Antimatter
