From the popular science media, we learn that Einstein spent the last 30 years of his life on a fruitless search for a theory that would bring all the forces of nature into one giant theoretical scheme. In this mini-monograph, which is an effort to try and achieve Einstein''s seemingly elusive dream, we improve on Weyl''s brilliant but failed geometry. We bring all the forces of nature into a unified theoretical scheme. Our scheme not only brings all forces together, but also quantum physics and gravitation under one unified theoretical framework. What is unique about the theoretical scheme that we have discovered, is that, all the forces of nature together with gravity and quantum mechanics, are all unified on a four dimensional continuum of spacetime.
