‎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.

The firstpart of the paper conatins a description of observations on the cathode rays, made with a Lenard Tube, in which the cathode rays passed through an aluminium window into an extension of the tube where as high a rarefaction as possible was maintained. The magnetic and electrostatic deflexions of a narrow cathode stream were observed and Wien concludes that it is proved by his investigation that the cathode rays which pass through the windoww carry with them strong negative charges.""(Magie ""Souce Book in Physics"", p. 597 ff.).Wien was awarded the 1911 Nobel Prize for physics for his discoveries regarding laws governing the radiation of heat.‎

‎First appearance of the paper which describes the final version of his invention, the famous Cloud-Chamber, - the first Cloud Chamber was invented by him in 1896 - for making visible and photographing the paths of charged particles, an invention for which Wilson received a share of the Nobel Prize in 1827. By using the Cloud Chamber he was here (1911) able to observe the track of an alpha ray by condensing water drops onto the ions produced by its passage.The Cloud Chamber, which Rutherford called ""the most original apparatus in the whole history of physics"", became standard equipment in physics laboratories, and made possible numerous important discoveries in the fields of particle and nuclear physicsAfter 1896 ""Wilson continued to experiment with ultraviolet radiation and other techniques for producing condensation effects, but soon concentrated on atmospheric electricity, not returning to the cloud chamber until December 1910. He designed an improved chamber with new methods of illumination and the possibility of photographing the results. At this time Wilson realized that it might be possible to reveal the track of an a ray by condensing water drops onto the ions produced by its passage. During March 1911 he saw this effect produced in his apparatus. Thus, the elucidation of phenomena seen in the Scottish hills led to the possibility of studying the processes of radioactivity, and the Wilson cloud chamber became an important piece of laboratory equipment. But it was in the study of cosmic rays that it achieved its full power, particularly in the refined form developed by Patrick Blackett, in which it was possible to study particles of very high energy and the production of electron-positron pairs with the chamber situated in a strong magnetic field.""

‎First printing of this groundbreaking paper in which Wilson describes the invention which made it possible to view the track of a single atomic projectile or electron. The invenvention of the ""Dust-Chamber"" made it possible for J.J. Thomson in 1897 to calculate the charge of the electron, and thereby finding its mass, since the ratio between the two was known. In most cases it was found that the track of the particle is a straight, or nearly straight line.""C.T.R. Wilson had been developing his cloud-chamber, which was to provide the most powerfull of all methods of investigation in atomic physics. In moist air, if a certain degree of supersaturation is exceeded this can be secured by a sudden expansion of the air) condensation takes place on dust-nuclei, when any are present: if by preliminary operations condensation is made to take place on the dust-nuclei, and the resulting droplets are allowed to settle, the air in the chamber is thereby freed from dust. If now X-rays or radiation from a radioactive substance are passed into the chamber, and if the degree of supersaturation is sufficient, condensation again takes place: this is due to the production of ions by the radiation. Thus the tracks of ionising radiations can be made visible by the sudden expansion of a moist gas, each ion becoming the centre of a visible globule of water. Wilson showed that the ions produced by uranium radiation were identical with those produced by X-rays."" (Whittaker in ""A History of the Theories of Aether & Electricity"" II:p.4).‎

‎Together with the English version - published 1912 in the Proceedings of the Royal Society - this is Wilson's main paper relating ""that the track of an ionizing particle might be made visible and photographed by condensing water of the ions which is liberated"". The first trails were obtained in 1911 where he submitted a short note of this to the Proceedings. In the offered paper he published the first tracks made by the ionizing particles of alpha, beta and Röntgen-rays. This, Wilson Cloud-Chamber, became an extremely valuable instrument of fundamental research, the discovery of the positron in 1932 and the kaon in 1963 were made by using cloud chambers as detectors.""But the whole course of the particle appears infinitely more clearly by the method invented by C.T.R. Wilson in 1911 and named after him. The radiation is allowed to enter an expansion-chamber, containing a gas saturated with water vapour. A sudden expansion of the chamber cools the gas, and cloud-drops are then formed instantly around the ions produced along the tracks of the particles. By suitable illumination these tracks can be made to stand out clearly as if they had been described by luminous projectiles. The ""Altmeister"" of modern nuclear physics, Lord Rutherford, once called the Wilson chamber ""the most original and wonderful instrument in scientific history"".""Thomson Rees Wilson (1869-1959), a Scottish physicist, is credited with inventing the cloud chamber. Inspired by sightings of the Brocken spectre while working on the summit of Ben Nevis in 1894, he began to develop expansion chambers for studying cloud formation and optical phenomena in moist air. Very rapidly he discovered that ions could act as centers for water droplet formation in such chambers. He pursued the application of this discovery and perfected the first cloud chamber in 1911. In Wilson's original chamber the air inside the sealed device was saturated with water vapor, then a diaphragm is used to expand the air inside the chamber (adiabatic expansion). This cools the air and water vapor starts to condense. When an ionizing particle passes through the chamber, water vapor condenses on the resulting ions and the trail of the particle is visible in the vapor cloud. Wilson, along with Arthur Compton, received the Nobel Prize in Physics in 1927 for his work on the cloud chamber. (Wikipedia).‎

Wilson...It was a wonderful advance to be able to se, so to speak, the details of the adventures of these particles in their flight through the gas....""(Lord Rutherford).""C.T.R.

Wilson received the Nobel prize - together with Arthur Compton - in physics in 1927 for his work on the Cloud Chamber.""The 21 cloud chamber pictures of X-rays and beta-rays on coated stock printed recto only were the culmination of many years research by Wilson and at last showed the full potential of this method as a tool for particle physicists. Early in 1911 (Wilson) was the first person to see and photograph the tracks of individual alpha-particles and electrons. The event aroused great interest as the paths of the alpha-particle were just as W.H. Bragg had drawn them in publication some years earlier. But it was not until 1923 (the paperoffered) that the clous chamber was brought to perfection and led to his two, beautifully illustrated classic papers on the track of electron.""

Une des innovations de Kelvin est l'introduction d'un « zéro absolu » correspondant à l'absence absolue d'agitation thermique et de pression d'un gaz, dont il avait remarqué les variations liées selon un rapport linéaire. Il a laissé son nom à l'échelle de température, dite absolue, ou température « thermodynamique », mesurée en kelvins.

(source : Wikipedia) - George Gabriel Stokes (13 août 1819 1er février 1903), 1er baronnet, est un mathématicien et physicien britannique né en Irlande. Ses contributions majeures concernent la mécanique des fluides, l'optique et la géodésie. - Il publie, en 1845, le résultat de ses travaux sur les mouvements des fluides dans sa thèse On the theories of the internal friction of fluids in motion. Son approche mathématique décrivant l'écoulement d'un fluide newtonien incompressible dans un espace tridimensionnel, en ajoutant une force de viscosité à partir des équations d'Euler (Principes généraux du mouvement des fluides, 1755), est à l'origine des équations de Navier-Stokes. L'ensemble de ses recherches est synthétisé par son traité Report on recent research in Hydrodynamics, paru en 1846, texte fondateur de l'hydrodynamique. Il exploite ses expériences sur le mouvement d'un pendule dans un fluide pour étudier les variations de la gravitation à la surface de la terre et publie On the variation of gravity at the surface of the earth en 1849, ce qui fait de lui « l'un des initiateurs de la géodésie ». En 1852, dans On the change of refrangibility of light, il explique le phénomène de la fluorescence en constatant que certains matériaux, tels que le fluorine (CaF2) et l'ouraline, émettent la lumière visible lorsqu'ils sont exposés au rayonnement ultraviolet, qui possède une longueur d'onde inférieure.
