- Kalki, get your definitions streight. The information content is the _size_
- of the smallest UTM that can generate the mandelbrot set (which is probably less
- than average) not the length of time it takes to run.
-
- By that argument the information content of the physical laws is infinite. It
- is impossible for a computer to compute the exact solutions to the pendulum
- problem.

-
- there you go, switching paradigms again. Information content is _not_ the
- size of the computer program, it is the size of the UTM. Unless you own a
- univesal turing machine (which is extremely doubtful) the two will be completely
- different.

-
- PI (the number), comes to mind. The actual information content is small since
- PI=4-(4/3)+(4/5)-(4/7)+(4/9)-..., which is a simple program to write. (only a
- little more comlicated than the division and addition routines).
-
- Some intergrals, a number of PDEs, ODEs, and BVPs also come to mind. Much
- game theory. Some combinatorics, statistics, and higher levels of algebra.
