Now who is setting up dichotomies with loaded use of the word "modern"?

You and your co-authors, in "Structure and Interpretation of the 
Computer Science Curriculum", rightly criticize SICP for requiring too 
much domain knowledge. One obvious use of world.ss is in simulation of 
physical phenomena -- but this requires domain knowledge in physics at 
least (maybe even fluid dynamics), not to mention knowing how to deal 
with computation using inexact numbers, something I would rather avoid 
in first year.

There must be non-gaming uses of world.ss that use discrete mathematics 
and have serious computer science content. I just have difficulty, 
personally, coming up with them. --PR
