Body Quote by Kenneth E. Boulding

A second possible approach to general systems theory is through the arrangement of theoretical systems and constructs in a hierarchy of complexity, roughly corresponding…

A theory is just a mathematical model to describe the observations.

— Karl Popper

“systems theory or, as some people might call it, complexity theory? The simplest explanation is that it is the study of interactions.”

— Rich Jolly

The heart of mathematics consists of concrete examples and concrete problems. Big general theories are usually afterthoughts based on small but profound insights; the…

“idea models—models that are simple enough to study via mathematics or computers but that nonetheless capture fundamental properties of natural complex systems.”

— Melanie Mitchell

Experience has shown repeatedly that a mathematical theory with a rich internal structure generally turns out to have significant implications for the understanding of…

A theory is a good theory if it satisfies two requirements: it must accurately describe a large class of observations on the basis of…

One advantage of exhibiting a hierarchy of systems in this way is that it gives us some idea of the present gaps in both…

With the subsequent strong support from cybernetics , the concepts of systems thinking and systems theory became integral parts of the established scientific language,…

The Theory of Groups is a branch of mathematics in which one does something to something and then compares the result with the result…

...the source of all great mathematics is the special case, the concrete example. It is frequent in mathematics that every instance of a concept…

We lay down a fundamental principle of generalization by abstraction: The existence of analogies between central features of various theories implies the existence of…
