Judging by the mathematical symbols and equations painted on the floor and wall of the Crane's studio theater, I was expecting Another Revolution to be a math play (which I love, BTW). But this new play by Jacqueline Bircher, produced by Market Garden Theatre, is less about math than it is about science, and it's less about science than it is about friendship, politics, protest, war, and coming of an age in a tumultuous time. The tumultuous time in this case is 1968, but it's not too hard to translate it to today's world, which has plenty to protest and is still sending young people to war. In addition to math plays, I also really love two-people-sitting-in-a-room-talking kind of plays, and that's what this play is. It's like eavesdropping on a conversation between two specifically drawn characters who couldn't be more different, but find common ground, and maybe even friendship, when forced to spend a few months together. This is also one of those plays where nothing really happens, and everything happens. Both are true. I left the theater looking at the sky differently than when I walked in. What more can you ask of theater than a discussion of ideas big and small, and a different outlook on the world?
