A comprehensive rewriting of the metaphorical book on imaginary numbers that defines them in logical and rational terms with examples anyone can understand, even computers. Then expands their applications in algebra, quadratic equations, defining radians, circular and hyperbolic functions. Identifies and defines their roles in entropy exploring topics in topology, differential equations, and partial differential equations. Applies the concepts to elementary entanglements like gluons, magnetic field induction through the dynamo-effect, and time. Re-evaluates Euler's Complex Variables and Helix differentiating mechanical rules for which heuristics are devised from applied understanding of imaginary numbers upon which exact solutions can be obtained. A concise treatment useful to students, teachers, and experts in mathematics and physics. Includes the text of Phase Theory of Everything, the cosmology (including Unified Field Theory) and related mathematical systems resulting from and coinciding with applications of imaginary numbers. This text in full color also appears under this title and in large print in Phase Theory of Everything. Metastar and white hole data appearing in a paragraph of the "Lemaitre Epoch" section of "Bang Starts Here" chapter is incorrect and was overlooked in editing. The correct estimates appear in the comparative table in the next ("Pre-Quasar Epoch") section. Further corrections, should they be necessary, will appear at akademe.org.
