According to this study that combining almost all physics laws and theories -from Newton's Mechanics, Einstein's Relativity...to 11D Super String theory- in form of unique unified field structure in Space-time, a Modern Age Principia can be said. This volume contains instead of the Theory of 5D Relativity can be defined as a mathematical generalization..so also provides some importants results.According to this study that combining almost all physics laws and theories -from Newton's Mechanics, Einstein's Relativity...to 11D Super String theory- in form of unique unified field structure in Space-time, a Modern Age Principia can be said..
