## Introduction

This site presents a non-mathematical overview of the re-working of Einstein's Special Theory of Relativity by John Field, who is a retired researcher at the University of Geneva, working at CERN. Starting from novel premises, and presented in an ongoing series of scientific papers, Field's analysis leads to the conclusion that time dilation arises without length contraction or differences in simultaneity. I.e. That special relativity is compatible with absolute simultaneity. However, and most controversially, this suggests that the Reciprocity Principle does not apply to special relativity.

This overview has been approved by John Field, who has kindly allowed his unpublished papers to be hosted on this site. These provide further insight into his ideas. Collectively, the published and unpublished papers represent a fundamental revision of the subject.

## The Lorentz Transformation

John Field's paper "A New Kinematical Derivation of the Lorentz Transformation and the Particle Description of Light" distinguishes between the kinematic (i.e. space-time geometric) and the dynamic (i.e. concerning transformation laws of fields and forces) aspects of the transformation.

By this means he derives the Lorentz Transformation without assuming Einstein's second postulate (that the velocity of light is constant in all frames of reference). Instead, he uses three novel postulates to show that Einstein's second postulate is a necessary CONSEQUENCE of relativistic kinematics, if it is assumed that light consists of massless particles. The postulates are:

- A weak kinematical form of Einstein's first postulate (the Special Relativity Principle), that requires that space-time measurements in reciprocal experiments by two different inertial observers will be the same.
- Uniqueness. I.e. That the Lorentz Transformation should give a single solution for the description, in any frame, of a given space-time experiment.
- Spatial Isotropy. I.e. That space is uniform in all directions.
