Mathematik and Dynamical Systems. Mathematical visual effects and games, mostly javascript-based.

Neat! thanks. I hadnt seen the dynamical systems site.

Many of these are open Hamiltonian problems and the models are approximations.

Curiously, the matter of whether our own solar system is stable is still really an open problem (though it is likely chaotic but bounded)

I like math. Especially when it is animated.

Okay, I have a question about the Turing Machine section. The site states that "A challenging sport is to find among all Turing machines with n states the 'busy beaver,' the program, which produces from the empty band a maximum number of consecutive 1's before it halts."

It seems to me that just setting all the rules to 1R1 will move along the tape infinitely, setting each memory location to 1 as it goes. By saying "before it halts," does that mean that the program needs to come to a halt eventually to satisfy the problem?

patgas: yes. Note that this problem becomes uncomputable very quickly.
