This play by Susan Yankowitz centers on what physicist Steven Hawking calls the two remaining mysteries: the brain and the cosmos. The work looks at what happens to a bright, articulate astronomer, her family and her career when she is struck by a car and loses her ability to speak conventionally, a condition known as "aphasia." As she is left to expresses herself in an alternately funny, poetic, confusing and profound hodge-podge of words her daughter, fiancé and colleagues face uncommon challenges as they discover new ways to communicate. Tues.-Sat., 8; Sat. & Sun., 3. Call for variations in schedule. (Through 6/20)
