Civilizations have two important properties: they are dissipative systems, and they are creative systems. A dissipative system is a physical system that maintains its state by turning resources from a usable form into an unusable waste form. In terms of physics (specifically: thermodynamics) one can describe them as dynamic systems that produce entropy (i.e. they […]

Civilizations – Part 4

(continued…) The standard view on resources is to treat them as being external to the system. So we perceive the extension of the system of our civilization as growth. But while this system is growing, the resources are shrinking. If growth happens at a constant rate (measured in percent), it is actually exponential, so the […]
