New Ideas on Special Relativity and Electrodynamics

By Georg Lentze

This book is not a textbook. It starts by querying a cornerstone of classical physics: the constancy of the one-way speed of light. This constancy is found to rely on a definition of time coordinates which does not establish a meaningful relationship of simultaneity. The book then asks why the two-way speed of light is constant for every observer. It argues that this constancy is a result of lengths being contracted and times dilated for any observer moving through a frame of reference in which light propagates in symmetrical conditions. A new model of electricity is presented which explains electric length contraction and time dilation in such a frame of reference without using the concept of magnetism and without assuming the constancy of the two-way speed of light.
