内容简介：
This is a collection of articles that place emphasis on the most observable aspects of relative motion, i. e., aberration effects, to ultimately define what the author calls "observational relativity." The reader will gain valuable insights into all aspects of relativity using the many informative diagrams and illustrations provided whether the author's alternative interpretations are accepted as superior or not. It is written for the intelligent (maybe very intelligent) reader, but very little in the way of advanced mathematics is required to fully comprehend the arguments.
