Time suddenly became of paramount importance for me when out of town travel and a January snow storm converged to almost cause me to miss seeing this play.  Having followed Hannah Moscovitch's work since I first saw East of Berlin and the double bill of The Russian Play and Mexico City, a decade ago I was curious to see how she could create an engaging work about a physicist studying the nature of time.  As an aside, one of my sons is a theoretical physicist, excellent at explaining abstract concepts yet the only part of his PhD thesis I understood was the dedication.
