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 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.
