Music is, of course, a universal emotional experience, cutting across cultures and languages. I studied piano for ten years as a child and consider that experience one of the most valuable in my life.

For me, consciousness is the most interesting unsolved problem of science, and, in fact, we may never know what it is about a particular arrangement of neurons that gives rise to consciousness. Our consciousness, like the air we breathe or like the passage of time, is central to our existence as intelligent beings.
