[++] "Going Right and Making It Wrong: The Reception of Fizeau s Ether-Drift Experiment of 1859" by Jan Frercks, Boston Studies In The Philosophy Of Science book series (BSPS,volume 267) . "For Hippolyte Fizeau, everything in his ether-drift experiment of 1859 [one part of which is offered here in the CR, followed shortly thereafter the same year and in 1860 in the Annales de Chymie et de Physique] went right.1 He had expected a change in an optical effect caused by the motion of the Earth, and, indeed, he measured this change. The data corresponded neatly with his theory-based prediction. This was the first demonstration of the motion of the Earth with respect to the luminiferous ether. In fact, it remained the only experiment which proved such an effect. According to present-day knowledge, however, the effect deduced and measured by Fizeau is known not to exist, signaling that something must have gone fatally wrong in Fizeau s experiment. The problem is not that the experiment is based on the assumption of an ether, which is today is regarded as non-existent. The problem rather is that the data themselves must be judged as wrong in the sense of referring not to nature, but to some (unknown) property of the apparatus or the measuring procedure."

By the middle of the nineteenth century, most scientists had come to accept the wave theory of light, formulated near the beginning of the century by Thomas Young and Augustin Fresnel. There remained, however, several gaps in the investigation of the experimental consequences of the theory. For example, in the study of interference fringes produced by two rays of light issuing from the same source, only several dozen fringes on each side of the central band had been observed."--Dictionary of Scientific Biography.

Two French physicists, Jean Bernard Léon Foucault ( 1819 -1868 ) and Armand Hippolyte Louis Fizeau ( 1819 - 1896 ), attempted the determination for the finite speed of light; Fizeau did so singly in 1849 and again in 1850 together with Foucault but thereafter independently sought the speed of light in his famous 1851 Fizeau Water Experiment whenever light was transmitted thru a high velocity flowing medium such as water. In essence, therefore, Fizeau attempted to confirm Augustin - Jean Fresnel ( 1788 - 1827 )'s "velocity drag coefficient" for light transmitted thru high - velocity ( at least / approx. 30 m/sec ) flowing water. It should be thus noted that Augustin - Jean Fresnel, French mathematical theorist and experimenter in optical wave physics, is the original mathematical discoverer in 1818 of the velocity drag coefficient."--Dictionary of Scientific Biography.

French physicist Hippolyte Fizeau (18191896) independently discovered the Doppler effect for light in 1848 and in his presentation to the Société Philomathique de Paris he proposed that the motion of stars relative to the Earth can be measured through changes in their spectra. This led to astronomical spectrum analysis, perhaps the most important application of the Doppler effect. As a result, the Doppler effect is referred to in France as "effet Doppler-Fizeau." Fizeau's theory and proposal became known, but his presentation was not published until 1870 [the paper being offered for sale here].

In this paper, Clausius introduced the concept of entropy and stated the second law of thermodynamics in a form that is now widely recognized. He emphasized that heat does not spontaneously flow from a colder body to a hotter one, and he introduced the idea of entropy as a measure of the unavailability of energy for doing work. [++] "In 1851 [in the original appearance of the "Comptes Rendus." vol 33 pp 349-355, 1851, and which ap-pears here in translation I the same year] Fizeau found a way of overcoming the seemingly impossible difficulty of measuring the small increment in the velocity of light that in theory would be produced by a body in motion. His method was simply to produce interference fringes from rays of light that had passed through two parallel tubes containing a fluid moving in opposite directions. Even a relatively small difference in the velocity of the two light rays would cause a perceptible displacement of the interference fringes. Using air as the test medium, Fizeau discerned no change in the speed of light, a result that he expected because the refractive index of air is equal almost to one. With water, however, the velocity of light was altered by an amount that accorded reasonably well with Fresnel's formula. In 1886 A. A. Michelson and E. W. Morley repeated the experiment on a larger scale and confirmed Fizeau's results."--Complete DSB online.

First appearance of thispaper in which the authors demonstrated importent similarities between sound - and lightwaves, and that interference takes place between rays of light of different wavelenghts thus giving considerably evidence for the wave theory of light."By analyzing the white light source into simpler constituents by means of a spectroscope, Fizeau and Foucault were able to observe fringes produced by interfering light rays with a difference of travel equal to more than 7,000 wavelenghts, thus showing hat light waves, like sound waves, remain geometrically constant over a large number of periods. But light waves, because of their transverse vibrations, are more complex than sound waves. Light can assume different forms of planes of vibration as well as different intensities. Using the same spectroscopic apparatus as in the preceeding experiment, Fizeau and Foucault observed the interaction of two rays produced by passing a single polarized ray through a birefringent crystal. In this case, instead of obtaining alternating bands of light and dark, they obtained bands of light periodcally polarized in different planes of vibration."(DSB V, p. 19).

Fizeau shows that the velocity of light is higher in water flowing in the direction of the beam than that of light propagating in the direction opposite the direction of flow. The paper offered is the shorter announcement of the research, the paper in full was published later in 1859 in "Annales de Chimie et de Physique". Albert Einstein later pointed out the IMPORTENCE OF THE EXPERIMENT FOR SPECIAL RELATIVITY.Fizeau's result was replicated by Albert Michelson and Edward Morley in 1886 repeated the experiment on a larger scale and confirmed Fizeau's results., and in 1914 it was confirmed by Pieter Zeeman. It was Arago in 1838, who suggested this "crucial experiment" to decide between the corpuscular and undulatory theories of light by comparing the speed of light in water and in air. It vindicated the undulatory position.It was shown by Hendrik Lorentz (1892, 1895) that the experiment can be explained by the reaction of the moving water upon the interfering waves without the need of any aether entrainment. On this occasion, Lorentz introduced a different time coordinate for moving bodies within the aether, the so called Local time (an early form of the Lorentz transformation for small velocities compared to the speed of light). In 1895, Lorentz went a step further and explained the coefficient by local time alone and without mentioning any interaction of light and matter.

On this occasion, Lorentz introduced a different time coordinate for moving bodies within the aether, the so called Local time (an early form of the Lorentz transformation for small velocities compared to the speed of light). In 1895, Lorentz went a step further and explained the coefficient by local time alone and without mentioning any interaction of light and matter.

First printing of a highly importent paper in the history of physics, "It is less famous, for some reason, than the failure of Michelson and Morley to detect the aether drag, but NO LESS SIGNIFICANT. For it showed that the velocity of light increases in a medium according to the formula, v (1 - 1/n2), where v is the velocity of the medium, and n is the refractive index"(Gillespie in "The Edge of Objecticity" p. 427). Fizeau shows that the velocity of light is higher in water flowing in the direction of the beam than that of light propagating in the direction opposite the direction of flow. The paper offered is the full text of the research, there appeared an extract of it in Comptes Rendus in 1851. Albert Einstein later pointed out the IMPORTENCE OF THE EXPERIMENT FOR SPECIAL RELATIVITY.Fizeau's result was replicated by Albert Michelson and Edward Morley in 1886 repeated the experiment on a larger scale and confirmed Fizeau's results., and in 1914 it was confirmed by Pieter Zeeman.

1 lettre autographe signée 3 In-8 07/04/1889 bon Bellelettre de l'astronome Hippolyte Fizeau à Mouchez au sujet de l'inauguration de la statue de Le Verrier à l'Observatoire de Paris. "Je dois d'abord vous remercier au nom du comité de souscription pour le bienveillant concours que vous lui avez prêté dans la question si longtemps indécise de l'emplacement où l'on devait définitivement ériger le monument consacré au grand astronome. Je crois que les savants français et étrangers ainsi que tous les souscripteurs, se féliciteront de la décision prise à ce sujet, laquelle me parait satisfaire à la fois aux honneurs dus à Leverrier, à la haute valeur de l'oeuvre de Chapu, ainsi qu'à l'ornement de la cour et de la façade nord de l'observatoire". Il l'entretient ensuite des questions pratiques relatives à l'inauguration du monument : discours et prises de parole, invitations. Il insiste sur le fait de ne pas inviter les représentants de la ville de Paris. "Il n'est pas possible d'oublier la brutalité avec laquelle ce conseil a refusé de prendre part à la souscription et s'est trop longtemps opposé à l'érection de la statue sur la voie publique à la place accordée par le ministre des Travaux publics [.]". Physicien et astronome, il travailla sur la lumière et découvrit l'effet Doppler-Fizeau, si précieux aux astronomes, qui permit de déterminer la vitesse et l'éloignement des étoiles.
