Scope out this play

German author Bertolt Brecht first brought the "Life of Galileo" to audiences during World War II. He found parallels between Galileo's stunning theories of the universe and the turbulent '40s, when new technologies and the war were changing life dramatically. In David Edgar's modern translation, the epic debate between science and religion has relevance to modern issues such as global warming and cloning.
