Abstract :
An incremental method for modeling the essential system of life, in which physical attributes of life are brought together to improve the model of life, is explained. We present a tiny example that uses only four attributes, i.e. locality, metabolism, entropy reduction, and chemotaxis. These four attributes are translated into physical formulae and evaluated in a two dimensional simulation of an autocatalytic reaction. Autocatalysts injected into a vessel begin to flow toward the source of their substrate similarly to chemotaxis. At the front line of this flow, a subsystem associated with the four properties is detected. This kind of subsystem could be increasingly life-like if more critical attributes are used for detection. A database of the attributes is being made.
