Know Theatre presents David Auburn's play Proof. It explores the fine line between genius and madness in a family of mathematicians. A mathematician tries to "prove" her own genius against the memories of her recently-departed mathematician father. Actors Tim Gleason and Eric Young talk about their roles and the tensions and conflicts as the family strives for a resolution.https://wskg.org/audio/proofmix.mp3 photo courtesy tkamenick via Flickr
