Excerpt from the Book
Classical ether theory explains the Fizeau experiment
Regardless of the fact that A. Michelson and E. Morley explained the Fizeau Experiment [1, 2] in a very simple classical way [3], this experiment is sometimes used to demonstrate the validity of special theory of relativity[4]. Because some other experiments [5, 6] show that Doppler effect, which is generated within moving Medium, influence the average speed of light, it could be rather interpreted as an argument against special theory of relativity.
An attempt to measure the speed of light in the flowing water was accomplished 1851 by H. Fizeau [1, 2], whereby it turned out that the addition of the speeds does not correspond to the usual composition of vector values. It was shown however that the measurements confirm the ether drag theory, whereby the ether is to be only partly carried. Since the speed of light is in a medium also frequency dependent, Fresnel's theory cannot completely be in this case free of errors. Later it was shown that the results of Fizeau experiment can be derived by use of the relativistic addition of the speeds, if it is limited to small speed of the medium (M. Laue) [4], with the problem that relativistic addition of speeds is neither mathematically nor physically an addition but only a rule for the computation of a transcendental function of the sum of two numerical values.

Frequently Asked Questions
What is the fundamental focus of this publication?
The paper focuses on re-examining the Fizeau experiment through the lens of classical ether theory, arguing that it does not necessitate the assumptions of special relativity.
What are the central themes discussed?
The core themes include the behavior of light in moving media, the validity of Fresnel's carrying formula, and the mathematical derivation of light velocity in flowing water.
What is the primary objective of this work?
The goal is to provide a consistent physical explanation for the Fizeau experiment using classical concepts to challenge the exclusive interpretation of the results through special relativity.
Which scientific methodology is applied?
The author uses mathematical modeling and derivations, comparing calculated results with experimental observations and existing physical formulas like the Fresnel equation.
What topics are covered in the main section?
The main text covers the derivation of speed in moving water, the definition of the refractive index in relation to the medium, and the calculation of light velocity under varying flow conditions.
Which keywords best characterize the research?
Key terms include Fizeau experiment, Classical ether theory, Ether drag, Moving medium, and light speed composition.
How does the author view the relativistic addition of speeds?
The author argues that relativistic addition is not a true physical addition but rather a rule for computing transcendental functions, making it a limited interpretation.
Does the paper consider the Doppler effect?
Yes, the paper acknowledges that the Doppler effect, generated within a moving medium, influences the average speed of light and serves as a point of contention against relativistic interpretations.
What role does the "material portion" play in the author's theory?
The author distinguishes between the material (ponderable) portion of the light path that moves with the medium and the empty gaps where the ether remains uninfluenced.
