— Erik Jonsson is a very special person: a retired engineer who has practiced and studied the ways by which people wonder about the world, finding their way -- and losing it. I confess to a very special bias for Erik and this book. I have known Erik for years. I encouraged him to put his ideas into writing and to publish the book. And I wrote the introduction. But why not? To paraphrase my introduction, "I have learned more about the science of human navigation from this witty, quirky, fascinating book of stories than from the many scientific journals I read."Pointer to the book at Amazon.com
