Is the duckbilled platypus your thing? Does talk of faster-than-light travel in the cosmos and women's lib on earth and in space turn you on? Are you interested in learning how to help prevent the end of the world without abandoning civilization? Answer "yes" to any of these questions -- or if you just want to learn more about science and its relationship to man -- and you will enjoy this collection of Isaac Asimov's latest scientific essays, mostly reprints of articles published in magazines such as Look, International Wildlife, Smithsonian, and the Saturday Evening Post during the period 1969-72. Many of the pieces have been updated by the addition of "after-words" which serve the dual purpose of integrating the diverse essays into one more or less unified volume. Well prepared in the author's serendipitous style, this volume reads easily and is entertaining, appealing to readers interested in the natural world and the interactions of science and society.
