Relativistic Sagnac Effect

The book "Relativistic Sagnac Effect" by Biplab Raychaudhuri offers a comprehensive analysis of the conceptual questions associated with the relativistic Sagnac effect in flat and curved space-time continua. It addresses relevant topics related to rotating reference frames and examines various paradoxes of special relativity, including the Ehrenfest, Tippe-Top, and Selleri paradoxes. The author proposes innovative solutions that utilize the Sagnac effect as a tool to illuminate these complex issues. The discussion also includes the treatment of the Sagnac effect from the perspective of rotating reference frames, demonstrating that the Tangherlini transformation is the preferred method for representing absolute simultaneity. Furthermore, the Sagnac effect is addressed in curved space-time continua, deepening the understanding of relativity theory in various contexts. Two appendices provide an educational treatment of special relativity and the resulting transformations.
