"I've known the author circa fifty years; then, a young broad-based scientist with a good sense of humor; now, a broader-based scientist with a great sense of humor. Who better to develop an obsession with an unfunny, tantalizing, and unquantifiable topic like serendipity and produce a gem of a book analyzing its vital importance in the past and its great need in the future?" -James A. Young, chemist "Surprise! I didn't see that coming! P. J. Hannan has ably documented the major role of fortuitous findings in scientific progress." -Clifford M. Gordon, physicist "Hannan writes the story of serendipity in research where scientific egos, luck, and the'Hand of God' clash for credit." -Michael A.

These and many other situations are described in this illuminating book that will be enjoyed by all who like a good story.
