moving and what not

Helped roger move into his new place on Marlboro. In between I read some more bits of SICM. I’ve figured out that their “notation” appendix is critical reading. Much of their math and code doesn’t make much sense without a review of that bit. I’m making a little more headway in understanding Lagrangians. I think he action is a quantity which is zero along the stable, and realizable path. That path is also to a solution to a system of differential equations that relate kinetic energy to potential energy.
