MarkGuzdial (SqueakLanguage guy) on research into using a ProgrammingLanguage for representing physics problems.
Shows how notations affect our ability to represent problems.
This is a very interesting quote :
Bruce talks about algebraic notations leading to a physics of "balance and equilibrium" while programming leads to a physics of "processes and causation."
I guess this is similar to what goes on in other studies of complexity. Compare economics, which has tended towards studying equilibria problems (such as when markets clear) rather than dynamics of market-systems (which is what I'm interested in in Optimaes). And maybe (WarpLink) MediaAndMaterials
