Acknowledgments

This book is the product of many minds.

Guy Blaylock, Danny Greenerger, David Harrison, David Kaiser, Preston Stahley, and Arthur Zajonc read the manuscript and gave me the immeasurable benefit of their advice. Andrew Fraknoi and John Harte read an earlier article and similarly gave me much help. And over the years I have benefited greatly from—and enjoyed—illuminating conversations with innumerable colleagues and friends: some of them scientists working in the field, others nonscientists who nevertheless had insights that gently prodded me in productive directions.

Renate Bertleman, John Clauser, and Jain Wei Pan kindly contributed their own personal photographs of people and equipment.

To all my deepest thanks.
