The book: Physics – How does God manifest Himself in the Universe? God's Master Equation is a general audience scientific book that discusses the evolution of ideas in Physics throughout history covering its main areas of Classical Mechanics, Thermodynamics, Electromagnetism, and Quantum Mechanics, in addition to two others: Cosmology and Nonlinear Dynamics. God's manifestation is debated based on quotes from great scientists, such as Einstein and Newton, and scientific arguments, as well as quotes from the Bible and other religions. A chapter is devoted to the equation and associated theory that entitles the book. The language is accessible and the equations and examples presented are as simple as possible to reach a large audience. The book presents a proposal to consider a third important quantity in the Universe, which is Information, associated with Entropy. This topic is already known, but the author rereads it through a new interpretation, which absorbs the reader.
