The subject spread in this book is all over the map. If the subjects are related, the reader must intuit it . . . and they may be. The author is not mainstream, which is refreshing but sometimes frustrating. I wish for him a good editor and new title.Although I do not rate this book high for its smorgasboard topics, the revised edition's Epilogue rates a 5 simply for passing on Kunkel's theory that the Great Pyramid was a vacuum or hydraulic pump, complete with drawings and explanations. Since Kunkel self-published, his work may be lost except as preserved in Noone's book. Hats off to Noone for this alone.P.S. It's 5-21-00. The publisher should now lose the 5-4-00 fear-based readership, thank goodness.
