It is an interesting fact that during my tour I was never allowed access to computers, radios, or anything else that I might damage through curiosity, or perhaps something more sinister.
As a consequence while we had a roof over our heads, food on the table, and clothes to wear to school we were constantly conscious of being of modest means.
But the need for conflict to expose prejudice and unclear reasoning, which is deeply embedded in my philosophy of science, has its origin in these debates.
I also taught myself how to blow glass using a propane torch from the hardware store and managed to make some elementary chemistry plumbing such as tees and small glass bulbs.
In parallel with the development of my interests in technical gadgetry I began to acquire a profound love of and respect for the natural world which motivates my scientific thinking to this day.
It was at Bell Labs that I first made direct contact with real semiconductor experts and thus began to fully understand what amazing materials they were and what they could do.
It was at this moment that I wrote my first important paper in theoretical physics. I was 32 years old, 5 years beyond the alleged age of senility for theorists.
My mother also had us take piano lessons, and this had a similar effect. I hated those lessons, but I now play regularly for pleasure and have even tried my hand at composing.
My job at Stanford is rather different from the ones I had held previously in that my own ambitions must take a back seat to the well-being of the students with whom I work.
One of the terrific aspects of MIT in those days was the enormous variety of experimental work that either took place there or was talked about in seminars by outside speakers aggressively recruited by the faculty.
Over the course of time this gave us a deep respect for ideas, both our own and those of others, and an understanding that conflict through debate is a powerful means of revealing truth.
The questions worth asking, in other words, come not from other people but from nature, and are for the most part delicate things easily drowned out by the noise of everyday life.
To this day I always insist on working out a problem from the beginning without reading up on it first, a habit that sometimes gets me into trouble but just as often helps me see things my predecessors have missed.
