Title: Vision and hope can't be conveyed to troglodytes
Review: Sagan's brilliance lies in his ability to make intelligent readers wonder. Those who nit-pick and complain about pi are missing the point. Sagan used pi to show the existence of god because pi cannot be changed; it is built into the fabric of reality and only the creator of that reality could embed a message in pi. All in all, an incredible book by an extraodinary man.
