Summary: Interaction between two subsets of variables.
Steady state Morowitz' book Thermodynamics Morowitz' book Summary: If two variables do not communicate, either directly or indirectly, then any interaction Q that include them must go to zero.
Coding problem Summary: Minsky and Papert really get hold of the Perceptron.

Channel what is a channel? Summary: The Coding Problem, even when asked only of binary relations, does not always admit a solution giving equality. 7086 Summary: A channel must be coded into and coded out of.
Epistemology [56]: McCrea's "principle" (7113) "The less information we can get [about distant events] the less we need in order to make predictions that are testable
by observation.". Summary: Examples of a channel that must have Least Safe Capacity, though transmitting less.

Information and interaction Interactionincreases information by x ki Summary: Interaction between parts having inputs raises the complexity by x ki. i = number of inputs to each part; k = number of values (states) of each part).
Summary: Among systems all of full interaction, doubling the size of the systems multiplies the information demands by the number of
bits required initially.
Summary: Thinking variables into vectors does not raise the order of the highest non-zero interaction.
