When I was around 10 years old, I concluded that key to understanding the world was physics, specifically theoretical mathematical physics. I don't remember how I came to such a conclusion or exactly the arguments that buttressed such a view, but I was deeply affected by it. Albert Einstein was an early hero of mine. So was Dr. Who,
the BBC-based Time Lord who wandered not only the spatial but temporal
reaches of the cosmos. Both Einstein and Dr. Who were romantic figures
who mastered the essential nature of the world. I wanted to be like
them in their fame and in their fashion sense; Einstein's unkept mane
and the long scarf of the 4th Dr. Who figured large in my imagination. Thus did fame and fashion become linked to physics and ultimately to my Ph.D. work in Berkeley.
