Square waves and electrons are seriously some of the most beautiful, incredible things.
But for my money, how about logic? Why the hell do logical operators make sense, how have ideas with absolutely no physical basis taken a life of their own and woven all this magic around us?
I usually think of logic as rigorously defined language, rather than built-up math. (Math being based in the physical world, and language being purely ephemeral)
From that point of view, 'or' 'and' 'not' and 'xor' make perfect sense.
Seriously, I can understand the fascination with something so fundamental to programming. I'm just surprised the favorite editor wasn't mentioned.
