Math Man specializes in the mathematics of dynamical systems, in chaos theory. I dabble in chaos too, just in its embodied form, rather than the theoretical. Chaotic systems are not random, though they might appear to be. Given a particular set of starting conditions (two sons, one cat, teaching two classes, a spouse on leave), the unfolding of the system is completely determined (a December calendar that requires 5 colors to keep track of everyone's obligations).
Not every system ultimately leads to chaos (where every possible state is eventually experienced), some eventually arrive at an equilibrium state - called an attractive fixed point. I think I'm approaching a fixed point tomorrow, though I'm not finding it all that attractive personally! All obligations (musicals, concerts, dinners, rehearsals, auditions) are being sucked in to the 6 hours between 3 pm and 9 pm on December 13th. Some fixed points have basins around them, where the conditions all lead to the same end point (exhaustion?). Others find a new fixed point to hone in on with a subtle change in conditions. So what will the potential ice storm do to my spiral?
The spirals above are three related species in a damped oscillating chemical reaction.
The Jesuits hold that you can find God in all things, presumably even chaos. I note that ergodic is another term for chaotic. QED, or perhaps I should say AMDG?
