‎On a Method of making a Direct Comparison of Electrostatic with Electromagnetic Force" with a Note on the Electromagnetic Theory of Light. (Read June 18, 1868). - [THE INTRODUCTION OF THE ""ELECTRICAL FORMULATION"" OF THE ELECTROMAGNETIC THEORY OF LIGHT.]‎

‎First appearance of this major paper on electromagnetic dynamics, in which Maxwell improves the groundbreaking equations he had set forth in his famous paper of 1865, the ""A dynamical Theory of Electro-Magnetic Fields"". In the paper offered here, he for the first time proposed to base the electromagnetic theory of light solely on 2 equations. The paper is one of Maxwell's 5 most importent contributions to electromagnetism.""Formulas for the forces between moving charged bodies may indeed de derived from Maxwell's equations, but the action is not along the line joining them and can be reconciled with a dynamical principle only by taking into account the exchange of momentum with the field. Maxwell remarked that the equations might be condensed, but ""to eliminate a quantity which expresses a useful idea would be rather a loss than a gain in this stage of our enquiry."" he had in fact simplified the equations in his fifth major paper, the short, but importent ""Note on the Electromagnetic Theory of Light."" (1868), writing them in an integral form without the function A, based on four postulates derived from electrical experiments. This may be called the electrical formulation of the theory, in contrast with the original dynamical formulation."" (C.W.F. Everitt in DSB).‎

‎First appearance of Maxwell's landmark - and his very first published on electromagnetism - paper in which he anticipates many of the fundamental ideas presented in his famous four-part paper ""On Physical Lines of Force"" (1861-2) in which he derived the equations of electromagnetism. The present paper ushered in a new era of classical electrodynamics and catalyzed further progress in the mathematical field of vector calculus. Because of this, it is considered one of the most historically significant publications in the field of physics and of science in general.Maxwell began his researches on electromagnetism following the completion of his studies at Cambridge in 1854. They were aimed at constructing, at a theoretical level, a unified mathematical theory of electric and magnetic phenomena that would express the methods and ideas of Faraday as an alternative to the theory of Weber."" This programme was announced in his first article, 'On Faraday's lines of force', in 1856, and continued in two other major texts, 'On physical lines of force' in 1861-1862 and 'A dynamical theory of the electromagnetic field' in 1865. According to a famous passage in its preface, the Treatise (1873) represented the outcome of this programme"" (Landmark Writings, p. 569). ""Maxwell's first paper, ""On Faraday's Line of Force"" (1855-1856), was divided into two parts, with supplementary) examples. Its origin may he traced in a long correspondence with Thomson, edited by Larmor in 1936. Part 1 was an exposition of the analogy between lines of force and streamlines in an incompressible fluid. It contained one notable extension to Thomson's treatment of the subject and also an illuminating opening discourse on the philosophical significance of analogies between different branches of physics. This was a theme to which Maxwell returned more than once. His biographers print in full an essay entitled ""Analogies in Nature,"" which he read a few months later (February 1856) to the famous Apostles Club at Cambridge" this puts the subject in a wider setting and deserves careful reading despite its involved and cryptic style. Here, as elsewhere, Maxwell's metaphysical speculation discloses the influence of Sir William Hamilton, specifically of Hamilton's Kantian view that all human knowledge is of relations rather than of things. The use Maxwell saw in the method of analogy was twofold. It crossfertilized technique between different fields, and it served as a golden mean between analytic abstraction and the method of hypothesis. The essence of analogy (in contrast with identity) being partial resemblance, its limits must be recognized as clearly as its existence" yet analogies may help in guarding against too facile commitment to a hypothesis. The analogy of an electric current to two phenomena as different as conduction of heat and the motion of a fluid should, Maxwell later observed, prevent physicists from hastily assuming that ""electricity is either a substance like water, or a state of agitation like heat. ""The analogy is geometrical: ""a similarity between relations, not a similarity between the things related."""" (DSB)The 1856 paper has been eclipsed by Maxwell's later work, but its originality and importance are greater than is usually thought. Besides interpreting Faraday's work and giving the electrotonic function, it contained the germ of a number of ideas which Maxwell was to revive or modify in 1868 and later an integral representation of the field equations (1868),the treatment of electrical action as analogous to the motion of an incompressible fluid (1869, 1873), the classification of vector functions into forces and fluxes (1870), and an interesting formal symmetry in the equations connecting A, B, E, and H, different from the symmetry commonly recognized in the completed field equations. The paper ended with solutions to a series of problems, including an application of the electrotonic function to calculate the action of a magnetic field on a spinning conducting sphere.‎

‎First printing of Maxwell's paper on a method of exhibiting the relations of colours.""Maxwell worked on the generation of white light by mixing different colors and in 1860, published the paper On the Theory of Compound Colours and its Relations to the Colours of the. In this paper, he extended the work of Thomas Young who first postulated only three colors, red, green and violet are necessary to produce any color including white and not all the colors of the spectrum are necessary as first illustrated by Newton. He also incorporated Hermann G?nther Grassman's concept that there are three variables of color vision (spectral color, intensity of illumination and the degree of saturation). Maxwell showed that these color variables can be represented on a color diagram based on three primary colors. While Newton distinguished his principal colors from the painters triad of primary colors (red, yellow and blue), he supposed the identity of mixing rule for lights and pigments. Even though Helmholtz explained that the mixture of color lights is an additive process while the mixture of pigments is a subtractive process as illustrated in Figure 2, Maxwell made experiments and developed a complete theory to explain how this happens by creating a color triangle which was originally suggested by James David Forbes and illustrated that any color can be generated with a mixture of any three primary colors and that a normal eye has three sorts of receptors as illustrated in his 1861 paper On the Theory of Three Primary Colours. He chose the three primary colors as red, green, and blue."" (Sarkar, Pp. 4-5). From 1855 to 1872, Maxwell published at intervals a series of valuable investigations concerning the perception of colour, colour-blindness and colour theory, for the earlier of which the Royal Society awarded him the Rumford Medal. The instruments which he devised for these investigations were simple and convenient to use. For example, Maxwell's discs were used to compare a variable mixture of three primary colours with a sample colour by observing the spinning ""colour top."".‎

Ce fut à l'époque le modèle le plus unifié de l'électromagnétisme. Il est également célèbre pour avoir interprété, dans un article en quatre parties publié dans Philosophical Magazine intitulé On Physical Lines of Force, la lumière comme étant un phénomène électromagnétique en s'appuyant sur les travaux de Michael Faraday. Il a notamment démontré que les champs électriques et magnétiques se propagent dans l'espace sous la forme d'une onde et à la vitesse de la lumière. Ces deux découvertes permirent d'importants travaux ultérieurs notamment en relativité restreinte et en mécanique quantique. Il a également développé la distribution de Maxwell, une méthode statistique de description de la théorie cinétique des gaz. - In 1865 Maxwell resigned the chair at King's College, London, and returned to Glenlair with Katherine. In his paper 'On governors' (1868) he mathematically described the behaviour of governors, devices that control the speed of steam engines, thereby establishing the theoretical basis of control engineering. In his paper ""On reciprocal figures, frames and diagrams of forces"" (1870) he discussed the rigidity of various designs of lattice. He wrote the textbook Theory of Heat (1871) and the treatise Matter and Motion (1876). Maxwell was also the first to make explicit use of dimensional analysis, in 1871.

The internal friction (the viscosity) of the gas is determined by the probability a particle of layer A enters layer B with a corresponding transfer of momentum. Maxwell's calculations showed him that the viscosity coefficient is proportional to both the density, the mean free path and the mean velocity of the atoms. On the other hand, the mean free path is inversely proportional to the density. So an increase of pressure doesn't result in any change of the viscosity.‎
