Systems Science as a Subset of Other Sciences

Systems science is best seen as a science that consists of nested sub-sciences. It is presented most compactly using the notation of set theory. Let A represent a science of description. Let B represent a science of design. Let C represent a science of complexity. Let D represent a science of action (praxiology). Let E represent systems science. Then A ⊂ B ⊂ C ⊂ D ⊂ E illustrates the concept that we can learn something of systems science by first learning a science of description. ...
