Ueber die Energievertheilung im Emissionsspectrum eines schwarzen Körpers. - WIEN'S DISPLACEMENT LAW

189643069Leipzig Johann Ambrosius Barth 1896. 8vo. Contemporary half cloth with gilt title to spine. Band 58 of "Annalen der Physik und Chemie". Library stamp to verso of title-page. Light wear to edges and capitals and a damp-stain to the lower part of the last three leaves. Otherwise a clean and well preserved copy. The entire volume offered. Pp. 662-669. Entire volume: VIII 776 pp. 6 folded plates. First edition of Wilhelm Wien's highly influential paper on the phenomenon of radiation also known as Wien's displacement law. Wien followed Ludwig Boltzmann's approach when incorporating electrodynamics and thermodynamics in investigating radiation and its characteristics. "He argued that if a system reaches the same temperature by the increase of temperature or by the adiabatic compression of the volume containing heat radiation it should yield the same energy distribution. Considering also the Doppler effect of the radiation Wien arrived at an expression for energy distribution that states that the product of temperature and the wave length is a constant". Mathew Chandrankunnel Philosophy of physics 2000 4 p.Wien's empirical observations functioned as a starting point for Max Planck who wanted prove the theoretical foundation for Wien's wishing thus to justify the entropy law. Today Wien's approximation is also known as Wien-Planck law.This phenomenon was coined "Wien's displacement law" because the energy density curve is displaced correspondingly to the temperature; it implies that the hotter an object is the shorter the wavelength at which it will release most of its radiation. Wien's description of radiation awarded him the Nobel Prize in Physics in 1911. Wien's constant is today used in a wide range of different aspects of physics e.g. cosmic microwave background and the determination of how much energy is emitted from a light bulb.

MAXWELL, JAMES CLARK - THE "MAXWELL-DISTRIBUTION"S FINAL FORM - A MAIN PAPER IN 19TH CENTURY PHYSICSBiblio.com

On the Dynamical Theory of Gases." Received May 16 - Read May 31 1866.

186743456London Taylor and Francis 1867. 4to. No wrappers as extracted from "Philosophical Transactions" Vol. 157 - Part I. Titlepage to volume 155 and pp. 49-88. Titlepage with minor light browning at corners. Internally clean. A small stamp on verso of titlepage. First appearance of this seminal paper in its full version from "Transactions" representing the announcement of Maxwell's final "Theory of Gases" and introduces the "Maxwell Distribution" in its final form a statistical means of describing aspects of the kinetic theory of gases a theory together with his electromagnetic theory are considered to be SOME OF THE GREATEST ADVANCES IN PHYSICS OF ALL TIMES. Everett considers this paper 1868 to be Maxwell's greatest single paper. Maxwell's discoveries laid the foundations of special relativity and quantum mechanics.One of Maxwell's major investigations was on the kinetic theory of gases. Originating with Daniel Bernoulli this theory was advanced by the successive labours of John Herapath John James Waterston James Joule and particularly Rudolf Clausius to such an extent as to put its general accuracy beyond a doubt; but it received enormous development from Maxwell who in this field appeared as an experimenter on the laws of gaseous friction as well as a mathematician.In 1866 he formulated statistically independently of Ludwig Boltzmann the Maxwell-Boltzmann kinetic theory of gases. His formula called the Maxwell distribution gives the fraction of gas molecules moving at a specified velocity at any given temperature. In the kinetic theory temperatures and heat involve only molecular movement. This approach generalized the previously established laws of thermodynamics and explained existing observations and experiments in a better way than had been achieved previously. Maxwell's work on thermodynamics led him to devise the Gedankenexperiment thought experiment that came to be known as Maxwell's demon. unknown
