8. "The brain is evolutionarily hard-wired to do its best daydreaming only when it senses that it is safe to do so—when, in short, it is relaxed.

Or during Sunday afternoon walks on Glasgow Green, when the idea of a separate condenser seems to have excited the aSTG in the skull of James Watt. Eureka indeed."
- William Rosen, The Most Powerful Idea in the World: A Story of Steam
