There has always been a thin line between genius and crazy. Where does this line disappear? Proof revolves around Catherine, the daughter of a renowned mathematician with severe schizophrenia. The play explores the mystery of mathematics and the uncertainty of love through four characters who are at the same time funny, irritating, lovable, and vividly alive. Proof is in the Cafritz Theatre on November 18 at 7:30 pm and November 19 at 8:00 pm. Tickets are $10 and are available at the CSPAC box office.
