The MichelsonMorley Experiment: An Improved Method of Calculating Phase Shift in Moving Interferometer (2005, ~17 pages)
By means of the Michelson interferometer a number of experiments were carried out to demonstrate the translational motion of the earth. The author reanalyzes the method of calculation in these experiments, and shows that, when taking into account a factor so far judged negligible, the expectable total phase shift will be proportional to the fourth power of v/c (the ratio of translation speed to light velocity).
