current search for life elsewhere in the universe takes the form of broadcasting into space the mathematical symbol π. Implicit herein is the assumption that no civilization could develop radio reception unless it could understand that mathematical concept. But it is so enormously presumptuous to assume that life elsewhere is even three-dimensional or detectable by human senses at all, let alone be composed of discrete life units that solve problems by use of an intellect and employ symbols to communicate across space and time.
