First appearance of this classic paper which announced one of the most celebrated experiments in the history of physics and eventually led Einstein to his Relativity Theory.The experiment was expected to show the rate of the earth's movement through the ether"" they looked in vain for a difference between the speed of light in the direction of the earth's motion around the sun and the direction perpendicular to it. The failure of this experiment was a serious blow to classical scientific theories because it cast doubts on the existance of the universal ether which had been a basic principleof, for example, the Newtonian theories of the universe. (Vide PMM: 378, 401, 408).The paper appeared first in the ""American Journal of Science"" in November (as offered here), and was published a month later in ""Philosophical Magazine"" in a slightly modified form.""Michelson, trained at the U.S. Naval Academy, and Morley, minister turned chemist, began a series of experiments to determine the relation of ether drift and the velocity of light, effects of extremely minute values. They used a slightly silvered glass set angular to a ray of sunlight so that a part ofthe ray was transmitted, a part reflected out and again returned, thereby providing two paths, one perpendicular to the other. If drift existed, the superimposed rays would produce interference. None was observed, showing that the earth's motion did not affect the light's speed. The negative result held revolutionary implications which led directly thru Lorentz and Einstein to the acceptance of new standards of reference of time and space from geometry and cosmometry.""(Dibner)In 1919 Einstein met Michelson in California. At a dinner given in honor of them both, Einstein said in a speech ""You (Michelson) uncovered an insidious defect in the ether theory of light, as it existed, and stimulated the ideas of H.A. Lorentz and Fitzgerald, out of which the Special Theory of Relativity developed. Without your work this theory would today be scarcely more than an interesting speculation..."" In an interview in 1842 Einstein said: ""It is no doubt that Michelson's experiment was of considerably influence upon my work insofar as it strengthened my conviction concerning the validity of the Principle of relativity...On the other side I was pretty much convinced of the validity of the principle before I did know this experiment and its result. In any case, Michelson's experiment removed practically any doubt about the validity of the principle in optics and showed that a profound change of the basic concepts of physics was inevitable.""Michelson was awarded the 1907 Nobel Prize ""for his optical precision instrument (the inteferometer) and the spectroscopic and metrological investigations he has carried on.""Dibner: Heralds of Science: 161 (lising the later version from ""Philosophical Magazine"") - Norman 1505.- Magee ""A Source Book in Physics"", pp. 369 ff. (the later paper).The volume contains another paper by Michelson and Morley ""On a method of Making the Wave-lenght of Sodium Light the actual and practical Standard of Lenght"", pp. 427-430.

First European publication of this classic paper which announced one of the most celebrated experiments in the history of physics and eventually led Einstein to his Relativity Theory (see PMM 378,410,408). The paper appeared first in the ""American Journal of Science"" just one month before in November, not in August as stated in PMM. The offered paper appeared in the December issue 1887 and in a slightly modified form.Michelson was the first American to be awarded the Nobel Prize for Physics, in 1907, for the measurement of the speed of light through the design and application of precise optical instruments such as the interferometer, which was used in this experiment.""Michelson, trained at the U.S. Naval Academy, and Morley, minister turned chemist, began a series of experiments to determine the relation of ether drift and the velocity of light, effects of extremely minute values.

The seminal first edition of the first description of the first version of a series of experiments with the Interferometer, which was built by Michelson and with which he planned to measure the relative speeds of light-waves moving at right angles to each other - an experiment that would ultimately lead to the special theory of relativity. The series of experiments ended with the so-called ""Michelson-Morley experiment"", the results of which were published 6 years after Michelson's first experiment (the item offered here). The 1887 paper, written together with Morley, constituted an improved attempt of the 1881- version of the experiment. The experiments were designed to calculate the effect of the earth's motion on the passage of light rays through the ""luminous ether"", which was believed to surround the earth. The experiments were negative and as such led to the introduction of relativity.""Michelson tried to determinate the relation of ether drift and the velocity of light, effect of extremely minute values...no drift could be found and the ""negative result held revolutionary implications which led directly through Lorentz and Einstein to the acceptance of new standards of reference of time and space from geometry an cosmometry.""(Dibner).In 1919 Einstein met Michelson in California.
