Universal Topology and First Horizon of Quantum Fields 16 20 EN Wei Xu 1760 Sunrise Valley Dr. Suite 403, Reston, Virginia 20191, USA IJP2017513 10.12691/ijp-5-1-3 2016 9 4 2017 1 7 2017 2 15 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=PiV, 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�CGordon Equations. As a result, this becomes a groundwork in the quest for Unified Physics: the workings of a life streaming of yinyang dynamics ...
