Evolution from the classical dynamics W=P to the spacetime interwoven W=P+iV of modern physics, this paper demonstrates the yinyang physics of nature law: Universal Topology W=P±iV, that intuitively constitutes YinYang Manifolds and Dual Event Operations. Following the yinyang principle, its First Horizon naturally comes out with the YinYang Energy-State Equilibrium and YinYang Motion Dynamics, which replace the empirical “math law” and give rise to the general quantum fields to concisely include Schrödinger and Klein–Gordon Equations. As a result, this becomes a groundwork in the quest for Unified Physics: the workings of a life streaming of yinyang dynamics ...
