This inspired idea was begun by Brockman on the Edge website, as his annual forum for experts to answer one given question using layman's language. It has led to this fabulous book – a mine of accessible science that is food for mind and soul, in three-page essays apiece.
The question: "What scientific concept would improve everybody's cognitive toolkit?" Answers from a roster of 160 big brains (Matt Ridley, Brian Eno, Richard Dawkins, et al) traverse across the cosmos, deep time and the unconscious. A real must-read.
