In this study, I have benefitted from the encouragement of a few close acquaintances. Moreover, I received considerable support from the publishing company (Shin-Shisakusha, Tokyo) proprietor, Mr. Koichi Koizumi.
More than anything, this study could not have been accomplished without the precious achievements of the late Dr. Albert Abraham Michelson, as well as Mr. Henry G. Gale, Mr. Fred Pearson and many other co-operators. Words are not enough to express my admiration of them.
We also thank Crimson Interactive Pvt. Ltd. (Ulatus and Enago) for their assistance in the translation and editing of this manuscript.
Appendix: ＊1The Michelson–Gale–Pearson experiment (1925, Illinois, U.S.A.).
The outline is shown in Figure 4. An evacuated 12-inch pipe is horizontally constructed to form a 300 m×600 m rectangle.
The splitter divides the introduced light, and each ray of light travels
around the pipe in opposite directions.
A
gap of 0.25 wavelengths was detected between the two rays of light because of
the relative speed of Earth’s rotation ω0.
If
let θ is Illinois latitude then ω
= ω0 sinθ, in Illinois.
