A method for modeling life based on physical attributes.
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.
