Egrodicity

Egrodicity is an idea where a point of a moving system will eventually have travelled through all parts of the space that the system moves in. Like smoke in room and it eventually filling up the room. The egrodic theorem has been used to describe common-sense phenomenon like mixing of liquids from a mathematical point of view. An egrodic process is a process that has the same time average and ensemble average. A time average of a process is the value of the process over an amount of time. While an ensemble average is the average of N number of identical process at a specific point of time. An egrodic process can be understood by looking at a snapshot of the process rather than the complete picture.
