- Me too! It makes algebra *so* much easier. And teaching is a lot more
- fun when you can draw pictures of things instead of writing out strings
- of symbols.
-
- The trouble is that a lot of people (maybe more so in computer
- science?) are symbol oriented. They get very disoriented by your
- pictures and accuse you of being too intuitive. Then you have to
- translate for them, which is not only a pain but meanwhile you aren't
- talking to the visual people, so you end up explaining everything
- twice, or ignoring the symbol people if there isn't time. But the
- worst is program committees, which don't give you enough room to
- explain everything twice.

-
- Me too! Even when I'm thinking about red-and-black trees the nodes are
- white and black. (Come to think of it, maybe that's because they're
- colored that way in Cormen, Leiserson and Rivest.)
-
- So what's the cause? Do we think monochromatically because the great
- majority of textbooks are monochrome, or are textbooks monochrome
- because their authors have colorless ideas (when not sleeping
- furiously)?
-
- When I run out of bandwidth on the blackboard I revert to colored
- chalk. Axiom: there's never enough colored chalk, you have to bring
- your own.
