According to Littlewood's Law of Miracles (based on the theory of large numbers and probability), you should expect something truly unusual to happen every 35 days--so strange, in fact, that it will look like a miracle. This book, which is fully illustrated, explains how the improbable is probable by focusing on desultory decussation (where two random events from an interesting intersection--a synchronicity) and Littlewood's work in number theory at Cambridge University in the last century. Also explains such concepts as Apohenia and Patternicity.
