I found in science a mode of playfulness and imagination, of obsessions and fixed ideas. To my surprise, those who achieved the unexpected and invented the possible were not simply men of learning and method. More than anything else, they possessed extraodinary minds, enjoyed the difficult, and often were creatures of amazing vision. Those in the front ranks displayed exotic blends of passion and indifference, of rigor and whimsy, of naïveté and the will to power, in a triumph of individuality.
