Arthur Koestler of "Darkness at Noon" fame also wrote a little-read book titled "The Act of Creation." I originally bought it years ago because I thought it was about what we think of as "creativity" (art, poetry, sculpture, etc.), but it was all about the act of *scientific* creation. It was fascinating. He delved into Darwin, for example, and talked about the decades Darwin spent in research and travel and thought before having his Eureka moment of natural selection. It's well worth reading, especially in the context of this interview -- looking deeply into the links among our creations and discoveries and how we arrive at them.
