Closing Remarks 187 POSTSCRIPT 193 REFERENCES 197 INDEX 199 Preface D,URING my career in science, now nearly a half century in duration, I have grown more and more aware that success in science, paralleling success in most careers, comes not so much to the most gifted, nor the most skillful, nor the most knowledge- able, nor the most affluent of scientists, but rather to the supe- rior strategist and tactician. The individual who is able to ma- neuver with propriety through the world of science along a course that regularly puts him or her in a position of serendipity is often the one who excels. Consequently, I have long sought to observe the experiences and the personal styles of successful scientists and to identify common traits that might be acquired and used profitably by others as they direct their careers. This book is a summary of those observations and hence can serve as a guide to the ambitious young scientist or student of science. However, no matter how well we prepare and plan, no matter how carefully we make our decisions and guide our actions, fate still seems always to play a central role in our careers and our lives. Often an apparently insignificant incident turns out to be a critical step to important developments that follow. In this preface, I relate the chain of incidents that led me to the gateway of the world of discovery and hence ultimately to the writing of x Preface this book. In so doing I hope not only to set the stage for what follows but also to set an appropriate tone of caution for a book that purports, somewhat optimistically, to be a guide in a subject that is never fully predictable. In the fall of 1946, Columbia played Yale in the Yale Bowl. During the post—World War II years, the stature and caliber of Ivy League football was unusually high as war veterans returned to school and reinforced the normal complement of younger ath- letes. Stadia were filled; tickets were scalped; Ivy League teams made headlines. The contest in New Haven was a particularly exciting one. Yale dominated early play and led at the half by two touchdowns, but Columbia rallied to pull ahead late in the game and win. For me that game was especially memorable. In the last quarter, I was able to block a Yale punt and so set up the winning score for Columbia. It was a notable event in an athletic career that was otherwise largely undistinguished. Long forgotten by others, that moment of success will stand out in my memory for life. But strangely that unusual achievement was not the most important thing that happened to me during that game. An obscure event earlier began an unlikely chain of happenings that had a far more profound effect on my life. The event set me onto the trail of discovery in science and eventually onto the writing of this book. Surely unnoticed by spectators, and inconsequen- tial with regard to the outcome of the contest, the event was a key incident in the development of my career and my life. While blocking on one play, which as I recall was a routine plunge into the line for little gain, I foolishly put my outstretched hand on the turf. An opposing player promptly stepped on it—with his cleats, of course. The injury that resulted was not crippling, but it did require frequent application of liniment and bandage dur- ing the following week or so. The liniment was the critical ele- ment in what followed. At the time, I was taking an intermediate-level course in elec- tricity and magnetism. It was given by Professor Polykarp Kusch, later a Nobel laureate in physics. The course was designed for, and populated by, physics majors, of which I was one. Now it often happens that members of a particular subset of society develop a common social attitude toward certain matters outside the mutual interest that defines the subset. In this manner, Preface xl physicists and physics students of that era were conditioned to downplay or ignore athletics. They wanted to be like Oppen- heimer, not Dimaggio, or Davis and Blanchard, or Sugar Ray Robinson. Modern physicists are often sports minded and sports conscious, but they were much less so then. Consequently, no one in that physics class knew that I was an athlete, nor did I in turn know whether any of the other students were athletes. The liniment quickly changed that. The strong aroma that accompanied me as I entered the classroom was detected by all and immediately identified by one, a wrestler named Dick Ed- wards. Dick knew that the familiar odor came from the Columbia trainer's private concoction and immediately deduced that an- other varsity athlete was in the class. He sniffed me out and struck up a conversation. The camaraderie of athletes prevailed and we became friends. Without the liniment, we might never have become acquainted in the no-nonsense environment of that course. Dick, it turned out, would arrange my introduction to geophysics. At the end of the academic year, I made a late decision to forego my senior year of college in order to begin graduate study in physics at Columbia during the following semester. It was a sound decision academically but not financially. Life as a gradu- ate student was more expensive than I had anticipated. Early in the fall of 1947, I confided to a friend that I needed money and was seeking a job. As luck would have it, the conversation was overheard by Dick Edwards, and he kindly volunteered some help. Dick led me to an unfamiliar part of the campus and intro- duced me to his employer, Professor Maurice Ewing. In less than five minutes Ewing interviewed me, offered me a job, and I ac- cepted with delight.
