Research On The Simplicity Principle In Complexity Science

The simplicity principle is one of the important principles of scientific methodology,which develops in the long-term theory and practice. Many people have wrong understandings on the principles of simplicity. This article is intended for detailed description and analysis of relevant content and grasping or understanding objectively and comprehensively.On one hand, firstly, thought of simplicity of ancient Greece from Pythagoras, Aristotle;the theoretical principles of simplicity forming of Ockham’s Razor, Newton and J.W.Gibbs from 14 th century to 19 th century; "the economic principle" of Mach and the logical simplicity principle of Einstein mainly discuss the principle of simplicity of pre complexity science.What’s more, it discusses simplicity principle in complexity science from what is simplicity principle,on the rise of complexity science and on the end of simplicity principle,simplicity principle in complexity science,complexity science needs simplicity principle and simplicity principle in catastrophe theory.Finally, it illustrates the principle of simplicity significance in complexity science from two aspects.First, ontological and epistemological meaning; second, methodology of simplicity principle.On the other hand, simplicity principle in complexity science cannot be free to use. If we do not limit it, it will simply lead to one-sided orientation, resulting in lack of understanding of results. Newton’s classical mechanics is the system which puts form of motion together in the world simplified as a form of exercise machinery, ignoring different things and gaps of different levels of things. Therefore, as science continues to develop, it will retard the pace of scientific understanding.Thus, study of simplicity principle of complexity science need us grasp its significance correctly and use the role of the simplicity principle in science and cannot be single-faceted.Application of simplicity in complexity science epitomizes the catastrophe theory.Catastrophe theory, combining synergetics and dissipative structure theory forms the basis of mathematical theory, and they promote the further deepening of scientific theory,transformation of mode of thinking and enable the human society to develop to an unprecedented level.
