Physics of our Four-Dimensional Space

Why do we need a simple model to replace the standard model of physics ? How to realize the existence of fourth space dimension ? How does new physics of four-dimensional space explain or interpret some fundamentals of modern physics ? How does this new physics provide a classical picture of mass-energy conversion process ? How Schrödinger equation and de Broglie hypothesis are obtained from the equation that describes four-dimensional structure of fundamental particle ? How Coulomb force and strong nuclear force are unified ? How wave particle duality is resolved ? ... This short book provides very simple answers to these questions.
