Tilly, I started to read "Structure and Interpretations of Computer Programs" and it was right around the stuff you bring up above that I started to get lost. Too much for a guy who blew off H.S. more than he should have. So until I brush up on my math skills, do you know of a lighter introduction to the kind of concepts you mention above? Thanks, bro.
