The interferometric experiments on the convection of white light in flowing water first done by Fizeau in 1851 and later repeated by Michelson and Morley in 1886 are quantitatively meaningless. The work by Zeeman in 1914 on flowing water is in agreement with an incorrect formulation. His observations can also be interpreted to be in agreement with the conventional addition of speeds rather than the Einstein addition theorem. Zeeman's experiments with moving quartz rods led to ambiguous and inaccurate results. His experiments on moving glass rods are also quantitatively meaningless due to the use of white rather than monochromatic light. Experiments with a “ring” laser interferometer published in 1964 present results both in agreement and in disagreement with an incorrectly formulated prediction.
