The aim of this book is to provide a treatment of quantum Yang–Mills gravity, with an emphasis on the ideas and evidence that the gravitational field is the manifestation of space-time translational symmetry in flat space-time, and that there exists a fundamental space-time symmetry framework that can encompass all of physics, including gravity, for all inertial and non-inertial frames of reference.Contents:The Taiji Symmetry Framework (Leonardo Hsu and Jong-Ping Hsu):Space-Time Symmetry, Natural Units and Fundamental ConstantsThe Taiji Relativity FrameworkThe Principle of Limiting Continuation of Physical Laws and Coordinate Transformations for Frames with Constant AccelerationsCoordinate Transformations for Frames with Arbitrary Linear Accelerations and the Taiji Pseudo-GroupCoordinate Transformations for Rotating Frames and Experimental TestsConservation Laws and Symmetric Energy–Momentum TensorsQuantum Yang–Mills Gravity (Jong-Ping Hsu and Leonardo Hsu):The Yang–Mills–Utiyama–Weyl Framework for Internal and External Gauge SymmetriesYang–Mills Gravity Based on Flat Space-Time and Effective Curved Space-Time for Motions of Classical ObjectsExperimental Tests of Classical Yang–Mills GravityThe S-Matrix in Yang–Mills GravityQuantization of Yang–Mills Gravity and Feynman–Dyson RulesGravitational Self-Energy of the GravitonSpace-Time Gauge Identities and Finite-Loop RenormalizationA Unified Gravity–Electroweak ModelA Unified Gravity–Strong Force ModelOutlookAppendices:The Fock–Hilbert Approach to Local Symmetry and Conservation Laws in General Frames of ReferenceCalculations of Hμν in the Gravitational Field EquationTensor Properties of Physical Quantities in Taiji Space-Time

Prof Wu feels grateful that he had the opportunity to educate a group of extremely talented students and, in particular, to discover T D Lee's remarkable talent. Although creative talent is no doubt a product of nature, it must also be nurtured. Prof Wu has played a crucial role for an entire generation of physicists in China and has won great respect from former students such as C N Yang, T D Lee, K Huang, and countless others. Prof Wu's love of physics and his dedication in teaching and research will always be remembered.

The aim is to present some of the leading ideas and problems discussed by physicists and mathematicians. We highlight three aspects: formulations of gravity as a Yang-Mills field, first discussed by Utiyama; problems of gravitational theory, discussed by Feynman, Dyson and others; spacetime properties and the physics of fields and particles in accelerated frames of reference.
These unfulfilled aspects of Einstein and Yang–Mills' profound thoughts present a great challenge to physicists and mathematicians in the 21st century.

Ten of the fundamental experiments testing special relativity are also discussed, showing that they actually support a four-dimensional spacetime based on broad Lorentz and Poincaré invariance which is more general than and includes the special theory of relativity. The generalization of the concepts of simultaneity, physical time and the nature of the speed of light within a four-dimensional spacetime framework leads to the conclusion that the symmetries embodied by the special theory of relativity can be realized using only a single postulate — the principle of relativity for physical laws.

To simplify historical search many original articles written during the early days of relativity are included here as English translations, which can be very useful to the readers. Of particular interest is the role of Woldemar Voigt (1850–1919) on the emergence of relativity, which is being given its proper place here. The authors' own comments on these issues appear as separate articles placed strategically throughout the volume to emphasize specific points.”Professor George Leung

“Hsu's book shows many new aspects of Einstein's theory which are not taught in lectures or by any other books on this subject … His understanding and appreciation of physics together with his unconventional style of writing make, in my opinion, the book worth reading for every physicist who is interested in Special Relativity.”Andreas Ernst
