Wow, a fascinating programme.

I wish I had a better grasp of category theory, my ever-curious self has made several attempts at getting into it, I failed each time! Abstract vector spaces: yeah! Measure theory, Hilbert spaces: I can follow most arguments. Graph theory: I love it. Category theory: help!

On a biographical note: I read M&M's 1972 Limits to Growth as a boy in the mid-70s, it turned me into an environmentalist. My father had an MIT work connection and we had all sorts of 1960s MIT systems books at home. I patiently re-drew all the big flow diagrams from Limits to Growth by hand, on sheets of A3 paper. That was at the same time that I played through the dynamics of John Conway's Life, by hand, using coloured pens on huge sheets of grid paper. Somehow the two exposures (Meadows, Conway) are merged in my mind, these activities shaped the way young Roamer thought. I may have been 12 or thereabouts. Happy memories.
