Through the history of physics the retrospective, on a simple principle in the scientific understanding of the Not only is the simple physics of the theory of evolution direction, and simply reflects the natural law of physics is the inevitable result is to explore new theoretical physics in an effective Simple principle of scientific methodology is an important In the vast ocean of knowledge, more and more of the mysteries of nature were untied, the mountains of knowledge have been approaching the "big bang" In the scientific creation on the road, if we do not follow a simple principle, will inevitably cause the complex system of knowledge and large, become an obstacle to development thinking, difficult to be accepted by future In essence, the simple science of nature itself is the harmonious unity of the objective, is not entirely man-made "simple"
