Computing processes are ultimately abstractions of physical processes; thus, a comprehensive theory of computation must reflect in a stylized way aspects of the underlying physical world. On the other hand, physics itself may draw fresh insights and productive methodological tools from looking at the world as an ongoing computation. The terminformation mechanics seems appropriate for this unified approach to physics and computation.
