Time and Consistent Relativity: Physical and Mathematical Fundamentals establishes a new and original theory of time relativity, which is fully consistent. It explains why Einstein`s theory of time relativity is physically meaningless and mathematically based on tacit inacceptable assumptions, and why it represents the singular case from the mathematical point of view. The consistent relativity theory established in the book represents an exit from the situation created by Einstein`s theory of time relativity.

This original book presents novel results on time and its relativity that constitute the consistent relativity theory. The results are free of mistakes, inconsistencies, and paradoxes of Einstein`s time relativity theory. The author’s original discoveries and results constitute the new physical and mathematical fundamentals on time and its relativity. The book presentation is concise, clear, and self-contained. It covers the phenomenon of time and its properties and results in a definition and characterization of time. It enables the great variety of new mathematical results presented in the form of theorems and their corollaries and specifies the necessary and sufficient conditions for the corresponding statements to hold. The proofs are rigorous.

This book:

  • explains the physical nature of time
  • presents the definition and characterization of time
  • explains the physical sense of time relativity
  • rejects Einstein’s time relativity theory as the general one
  • proves that Einstein’s time relativity theory represents a singular case valid under tacit, physically meaningless and mathematically inacceptable, assumptions
  • generalizes and extends the Galilean-Newtonian meaning of time and its relativity
  • introduces various new classes of mathematical transformations related to temporal, spatial, and velocity coordinates and proves the necessary and sufficient conditions for their validity
  • discovers a great specter of new results on the time uniqueness, relativity, temporal speed
  • discovers and proves a great specter of new results on the velocity and its transformations
  • discovers and proves a great specter of new results on the light speed and its invariance and non-invariance
  • discovers and proves the relationship of the light speed and the upper limiting speed
  • opens new directions for further research in physics and mathematical physics.

Lyubomir T. Gruyitch, DSc, was a Professor at the Ecole Nationale d'Ingénieurs, which integrated with the Institut Polytechnique de Sévenans at the University of Technology Belfort–Montbeliard, in France (1993-2007). He was also the AECI Professor of Control in the Department of Electrical Engineering at the University of Natal, Durban, South Africa (1992/1993), and a Professor of Automatic Control in the Faculty of Mechanical Engineering at the University of Belgrade, Serbia (1964–1992). He has also been a visiting professor at Ecole Centrale, Lille, France (1992); at Louisiana State University, Baton Rouge, Louisiana (1989/1990); and at the University of Notre Dame, Notre Dame, Indiana (1988/1989); as well as Research Associate at the University of Santa Clara, Santa Clara, California (1972). He has continued his research, lecturing, and consulting activity.

Dr. Gruyitch is the author of several published books and many scientific papers on dynamical systems, on control systems, and on time and its relativity. He has participated at many scientific conferences throughout the world. He has been honored with several awards and honors, including being honored with Doctor Honoris Causa by French Republic and the highest award presented by the Faculty of Mechanical Engineering, University of Belgrade, for teaching and scientific contributions to the faculty, 1964–1992, and an award from the Yugoslav Air Force Academy for teaching achievements in the undergraduate course Foundations of Automatic Control.

Dr. Gruyitch is a Certified Mechanical Engineer (Dipl. M. Eng.), Master of Electrical Engineering Sciences (M. E. E. Sc.), and Doctor of Engineering Sciences (DSc), all from the University of Belgrade, Serbia.
