Biography

Miller obtained a doctorate in astronomy at Princeton University under Charles A. Young. In 1890, he worked at the Case School of Applied Science in Cleveland, Ohio teaching astronomy, later becoming the head of the physics department in 1893. Following the discovery of X-rays by Wilhelm Röntgen in 1895, Miller used cathode ray tubes built by William Crookes to make some of the first photographic images of concealed objects, including a bullet within a man's limb. Astronomy (Greek: αστρονομία = άστρον + νόμος, astronomia = astron + nomos, literally, law of the stars) is the science of celestial objects and phenomena that originate outside the Earths atmosphere, such as stars, planets, comets, aurora, galaxies, and the cosmic background radiation. ...

Aether research

In 1900, he began work with Edward Morley on the detection of aether drift, at the time one of the "hot" areas of fundamental physics. Following on with the basic apparatus as the earlier Michelson-Morley experiment, Miller and Morley published another null result in 1904. The experiments concern many physicists dealing with Albert Einstein's theory of relativity. 1900 (MCM) was an exceptional common year starting on Monday. ... Edward Morley (1887). ... The aether (also spelled ether) is a substance concept, historically used in science and philosophy. ... The Michelson-Morley experiment, one of the most important and famous experiments in the history of physics, was performed in 1887 by Albert Michelson and Edward Morley at what is now Case Western Reserve University, and is considered by some to be the first strong evidence against the theory of...

Miller continued with the experiment, conducting thousands of measurements and eventually developing the most accurate interferometer in the world at that time. The type of experimental apparatus Miller used was very delicate. Dayton Miller performed over 200,000 observations and experiments dealing with the aether and aether drift. A second publication in 1926 showed what appeared to be a small amount of drift, which Miller commented on at several meetings. A third, in 1933, continued the theme. From 1902 to 1933 Miller performed experiments producing more accurate measurements. This work on aether was published as a positive result for the existence of an aether drift. However, the effect Miller saw was tiny. In order for it to detect aether, the properties of aether drag would have to more pronounced. Furthermore, the measurement was statistically far from any other measurements being carried on at the time, fringe shifts of about 0.01 were being observed in many experiments, while Miller's 0.08 was not duplicated anywhere else -- including Miller's own 1904 experiments with Morley, which showed a drift of only 0.015. The measurements are perfectly consistent with a fringe difference of zero -- the null result that every other experiment was recording. The luminiferous aether: it was hypothesised that the Earth moves through a medium of aether that carries light In the late 19th century luminiferous aether (light-bearing aether) was the term used to describe a medium for the propagation of light. ... 1902 (MCMII) was a common year starting on Wednesday (see link for calendar). ... 1933 (MCMXXXIII) was a common year starting on Sunday (link will take you to calendar). ...


Einstein was interested in this aether drift theory and acknowledged that a positive result for the existence of aether would invalidate the theory of special relativity, but commented that altitudal influences and temperatures may have provided sources of error in the findings. Miller commented: ... Temperature is also the name of a song by Sean Paul. ...

"The trouble with Professor Einstein is that he knows nothing about my results. ... He ought to give me credit for knowing that temperature differences would affect the results. He wrote to me in November suggesting this. I am not so simple as to make no allowance for temperature."

During the 1920s a number of experiments, both interferometry based, as in Miller's experiment, and others using entirely different techniques, were conducted and these returned a null result as well. Even at the time, Miller's work was increasingly considered to be a statistical anomaly, an opinion which remains true today, given an ever growing body of negative results. Generally, a null result is a result which is null (nothing): that is, the absence of an observable result. ...


Shankland analysis

In 1955, Robert S. Shankland, S. W. McCuskey, F. C. Leone, and G. Kuerti performed a re-analysis of Miller's results. Shankland, who led the report, noted that the "signal" that Miller observed in 1933 is actually composed of points that are an average of several hundred measurements each, and the magnitude of the signal is more than 10 times smaller than the resolution with which the measurements were recorded. Miller's extraction of a single value for the measurement is statistically impossible, the data is too variable to say "this" number is any better than "that" -- the data, from Shankland's position, supports a null result as equally as Miller's positive. 1955 (MCMLV) was a common year starting on Saturday of the Gregorian calendar. ... Robert S. Shankland (1908–1982) was an American physicist and historian. ...


Shankland concluded that Miller's observed signal was partly due to statistical fluctuations and partly due to local temperature conditions and, also, suggested that the results of Miller were due to a systematic error rather than an observed existence of aether. In particular he felt that Miller did not take enough care in guarding against thermal gradients in the room where the experiment took place, as, unlike most interferometry experiments, Miller conducted his in a room where the apparatus was deliberately left open to the elements to some degree. Systematic errors are biases in measurement which lead to measured values being systematically too high or too low. ...


In Shankland's analysis, no statistically significant signal for the existence of aether was found. Shankland concluded that Miller's observed signal was partly due to error rather than an observed existence of aether holding radiant energy. Thus, a large, but indefinite, number of mainstream scientists today hold the conviction that any signal that Miller observed was the result of the experimenter effect, which was a common source of systematic error before modern experimental techniques were developed (ed, Miller did publish an 20th century textbook on experimental techniques; cf., Ginn & Company, 1903). Radiant energy is the energy of electromagnetic waves. ... The expectancy effect (or experimenter effect) is a common problem in scientific experiments, a researcher or subject expects a given result, and tends to find it in the data. ...

Scientific method refers to a body of techniques for the investigation of phenomena and the acquisition of new knowledge of the natural world, as well as the correction and integration of previous knowledge, based on observable, empirical, measurable evidence, and subject to laws of reasoning. ...


William Broad and Nicholas Wade, reporters who wrote Betrayers of the Truth: Fraud in Science (1983), have stated that scientists should have reviewed Miller's research more seriously at the time, and that their refusal to do so is evidence of incompetence and unprofessional conduct. Robert Crease argues that it would have been "irrational and unscientific" to suspend Einstein's theory because of a contrary experiment. In Crease's opinion, this would allow some antiscientific ideologues (eg., some Soviet scientists) to stop progress through falsification. [1]


Modern precision experiments have continually verified the results brought into question by Miller, discounting his repeated attempts. [2] [3] [4]


Other endeavors

Dr. Miller published manuals designed to be student handbooks for the performance of experimental problems in physics. In 1908, Miller's interest in acoustics led him to develop a machine to record sound waves photographically, called the phonodeik. He used the machine to compare the waveforms produced by flutes crafted from different materials. During World War I, Miller worked with the physical characteristics of pressure waves of large guns at the request of the government. Dayton Miller was elected to the National Academy of Science in 1921.

Miller's 1933 Cosmic Model (6802 words)
Miller’s observations are best fit by the model if the magnitude curves are presumed to be determined only by the apparent ether intake apexes, while the azimuth curves are presumed to be determined only by the apparent exhaust apexes.
Miller could not explain the effect in which the mean azimuth axis (24-hour average azimuth) is displaced generally eastward from North by as much as 55º.
Miller’s choice is weaker because it fails to account for the wide azimuth swings and the (mostly) eastward displacement of the mean azimuth axis, especially in the April and September epochs.
