Physics and Albert MIchelesen

A detailed Summary of Physics and Albert MIchelesen

ysics is a powerful word- this single word embodies everything that the universe encompasses- and everything even beyond this point. Excelling in the field of optics and broaching the topic of light, Albert Michelsen was a man who had made an important mark in this area that would make an everlasting impression in the world of physics.

During Michelsen's long career, he was able to explore the world of physics with a greater depth, due to the abundance of knowledge he had received in the area of physics by both learning and teaching it in his career- he initiated his career as earning the position as an instructor in physics and chemistry at the Academy. Later, in 1879, Michelsen was posted to the Nautical Almanac Office, Washington. He also visited the Universities of Berlin, Heidelberg, College de France and École Polytechnique. In 1883 Michelsen returned to America and became a professor of physics in the Case School of Applied Science. In 1890 he accepted a similar position at Clark University, Worcester, Massachusetts and in the year1892, Michelsen became the highly prestigious and distinguished role of the Professor of Physics and the first Head of Department at the new University of Chicago (http://www.nobel.se/physics/l

By himself, Albert Michelsen was already a fully adequately trained man in physics- he had already spent most of his life learning about this subject in school, and had later devoted the rest of his life in teaching it in return to other people, as well as discovering new inventions in this field. Later in his life, when he had teamed up with Morley, the end result in refining his devices were considered excellent considering the current time frame he was in, and when his spectrometer was even further redefined my Fourier's tweaking and readjustments, the end result was an amazing apparatus that aided the world of physics greatly.

During his lifetime, Michelsen accomplished a great deal in the physics world. Michelsen contributed a great deal in the area of optics, experimenting with some rather crude, but respectable versions, at that time, of approximating the speed of light (Gary Waldman, Introduction to light: the physics of light, vision, and color, Englewood Cliffs, N.J. : Prentice-Hall, 1983, p. 221).

These rough sketches led to the invention of a new apparatus- the interferometer. This device was designed to split a single beam of light into two different beams of light. After the divergence has both beams in two lines, perpendicular to one another, they are brought back together once more. If the waves of the light have not fallen back in place, the interference fringes of the alternating dark and light bands would show (Waldman, p. 146). The measurements of the exact width of the band along with the exact number of fringes that would be accounted for had measured up to the light ray's velocity. In fact, an equation was even used to intertwine these different components together: lambda = xd/L, where lambda, x, d, and L, equal the length of the wavelength, the distance from the screen, the width of the slit, and the distance of the central bright light to the first-order bright light (Paul W. Zitewitz, Physics: Principles and Problems, New York, NY: McGraw Hill, 1999, p.447).

Michelsen was credited to have found the best measurements of the rotating mirror in the year ninety twenty-six, with a measurement of 299,796 kilometers per second, with a marginal plus four, minus four, error. His very fist attempt was in the year eighteen seventy-eight- he then conjured a measure of 186,508 miles per second. However, in ninety twenty-seven, Michelson made his final measurement in the location of Mount Wilson in the state of Californ
