On The Effect Of The Motion Of A Body Upon The Velocity With Which It Is Traversed By Light

de Hippolyte Fizeau

~~26,49€~~ 23,84€ 10% IMEDIATO

DISPONIBILIDADE IMEDIATA

 On the Effect of the Motion of a Body upon the Velocity with which it is Traversed by Light is a seminal scientific treatise authored by the renowned physicist Albert A. Michelson in 1881. This groundbreaking work details Michelson's meticulous experimental investigation into the fundamental question of whether the motion of the Earth through the hypothetical luminiferous ether affects the speed of light as it travels through space. The book presents the theoretical background, experimental setup, and results of what would become known as the Michelson-Morley experiment, a pivotal moment in the history of physics. Michelson's narrative begins with a comprehensive review of the prevailing theories of light propagation, particularly the ether theory, which posited that light waves required a medium-ether-through which to travel. He then describes the design and construction of his innovative interferometer, an instrument capable of detecting minute differences in the speed of light along different axes of motion. Through a series of precise and carefully controlled experiments, Michelson sought to measure the expected variations in light speed as the Earth moved through the ether. The book meticulously documents the experimental procedures, including the alignment of mirrors, the use of monochromatic light sources, and the methods for minimizing sources of error. Michelson's clear and methodical exposition allows readers to follow the logic and reasoning behind each step of the experiment. The results, which showed no significant difference in the speed of light regardless of the direction of motion, challenged the ether theory and set the stage for the development of Einstein's theory of special relativity. In addition to its scientific content, the book offers insights into the spirit of inquiry and the rigorous standards of experimental physics in the late 19th century. Michelson's work is characterized by a commitment to precision, skepticism of untested assumptions, and a willingness to question established scientific dogma. On the Effect of the Motion of a Body upon the Velocity with which it is Traversed by Light remains a classic in the literature of physics, representing both a milestone in the understanding of the nature of light and a model of scientific investigation.
