Corn in rows; OO? I'm here, aren't I?; emacs is the piece of software I love the most.
Unfortunately, I'm not enough of a math person to understand everything Tilly was saying (even though one of my majors for my Bachelor's degree was math), so I don't know which I am, nor can I really guess. I hated my Real & Complex Analysis class, but it was intended as the hardest course in the major, if I remember correctly. Perhaps it's more accurate to say I struggled with it.
To take a minor point and nitpick it, I wonder if he didn't get Emacs and vim reversed: one of the points of vim -- as I understand it; I've only gone through a bit of vimtutor -- is that the same blocks can be composed in separate ways. If you know that 3j means "move down three lines", then d3j means "delete the next three lines". That seems more like algebra than analysis.
