Negative Positive
Title: Clever and entertaining while being informative
Review: Clifford Pickover covers a lot of bases. He explores the different kinds of creatures on Earth and suggests that aliens might take similar routes. He also explores what senses an alien might have, problems with communication, even alien sex. He selects some fine examples of aliens from science fiction writers.Pickover is not afraid to toot his own horn. He makes extensive references to his own work. There is also the standard ridicule of religious principles which no self respecting writer would leave out of his work. This is a good exploration of xenobiology and worth the read for anyone who speculates about the nature of extraterrestrials.
