This monograph consists of eleven chapters which develop the well known EinsteinCartan Evans (ECE and ECE 2) unified field theory which has swept the world of sciencein step with the knowledge revolution. In the first volume, ECE theory was systematically developed from geometrical first principles and applied to the unifi cation of gravitation and electrodynamics and the unifi cation of quantum mechanics and generalrelativity. In this volume unification is further perfected in nine chapters as follows. 1)"Introductory Overview on Achievements with ECE 2 Theory"; 2) "The Effect of Torsionon Geometry"; 3) "The Field Equations of ECE 2 Theory; 4) "ECE Theory of GravitationalOrbits"; 5) "Development of New Types of Spectroscopy"; 6) "The ECE 2 Vacuum"; 7)"Precession in Mechanics and Gravitation"; 8) "Triple Unifi cation: Fluid Electrodynam-ics"; 9) "Triple Unifi cation: Fluid Gravitation"; 10) "Unification of the Rainich Space: Properties of Elementary Particles"; 11) "New Assessment and Interpretationof Radiation Laws"; . The monograph has been translated into Spanish by Alex Hill (Spanish language section of www.aias.us. ) It has already been read tens of thousands of times of www.aias.us and www.upitec.org.
