This book addresses the odd phenomenon of seeing 11:11 (or 2:22, 4:44, etc.) on the clock more often than seems to make sense. Well, at least that is this book's starting and ending point. In between, taking up most pages, is discussion about a multiplicity of fascinating facts about numbers and ratios involved in science, religion, and the occult. Sounds weird, right? It is, yet some of this stuff is truly amazing and warrants serious attention. It's kind of like an "Idiot's Guide" or "For Dummies" book about mysteries involving numbers. It is quite compelling and well written, but it leaves you feeling unsatisfied because most of the concepts discussed require considerable elaboration to be properly understood, and all this book offers is bite-size info-nuggets that serve as an intellectual snack instead of a psychic supper. This book definitely engaged my mind and elicited a desire to learn more about certain mysteries.
