When I was young, I was fascinated by Einstein's (special) theory of gravity
(known as 'relativity') based on the idea that the four 'dimensions'
of "north-south", "east-west", "up-down" and past-future should be treated
together as a single entity: space-time. I used to try to visualize them mentally
in a kind of super-space - with minimal success!
My thinking was, as it were, mechanical - and I was became a mathematical
physicist for my later work. A strand of spirituality was there, but
only occasionally did I bring in spirituality, which now, in various forms,
is the sea in which I swim.
