Intrigued by Liouville's suggestion Thomson wrote several papers over the next few years based on Faraday's experimental results, including: On a Mechanical Representation of Electric, Magnetic and Galvanic Forces (1847). On the Mathematical Theory of Electricity (1848). On the Mathematical Theory of Magnetism (1851).

In particular a non-ideal gas, made to expand slowly through a porous plug so as to approximate a specified mathematical condition - constant enthalpy), would in general undergo cooling (essentially a transformation of atomic motion into work spent against the interatomic attractions)....But the appliocation of the Joule-Thomson effect to technology of refrigeration belongs to a later stage in the development of thermodynamics.""(DSB VII, p. 182).The Joule-Thomson effect or Joule-Kelvin effect describes the increase or decrease in the temperature of a real gas (as differentiated from an ideal gas) or a liquid when allowed to expand freely through a valve or other throttling device while kept insulated so that no heat is transferred to or from the fluid, and no external mechanical work is extracted from the fluid. The Joule-Thomson effect is an isenthalpic process, meaning that the enthalpy of the fluid is constant (i.e., does not change) during the process. It is named for James Prescott Joule and William Thomson, 1st Baron Kelvin who established the effect in 1852, following earlier work by Joule on Joule expansion in which a gas expands at constant internal energy. The Joule-Thomson effect is sometimes referred to as the Joule-Kelvin effect. Engineers often refer to it as simply the J-T effect.‎

[Entire volume: IV, 288, VIII pp.].‎

‎First English translation (and first translation in general) with 'considerable additions' (as stated on p. 75) of Thomson's highly influential paper in which he for the very first time occupies himself with - and anticipates the invention of - the quadrant electrometer, the portable electrometer, and the absolute electrometer. ""When resident in Paris he published in Lionville's Journal a paper [first publication of the present], in which he examined the experiments and deductions of Sir. W. Snow-Harris. This investigator had made an experimental examination of the fundamental laws of Coulomb. Thomson showed by pointing out the defects of Harris' electrometer that the results, instead of disproving these laws, actually confirmed them, so far as they went, from this examination dates Thomson's interest in electrometers, which led to the invention of the quadrant electrometer, the portable electrometer, and the absolute electrometer. "" (Lectures on Ten British Physicists of the Nineteenth Century, P. 57).""Thomson's extensive contact with Liouville led him to think more deeply about electrical theory. Liouville had heard of Faraday's work in electrostatics, or at least of the aspects in which Faraday claimed to have found that electrical induction occurs in ""curved lines."" The conception seemed to conflict with the action-at-a-distance approach, and Liouville asked Thomson to write a paper clarifying the differences between Faraday on the one hand and Coulomb and Poisson on the other. This request prompted Thomson to bring together ideas he had been turning over in his mind during the previous three years.From Thomson's new point of view, both the French approach to electrical theory and that of Faraday should consist only of sets of mathematical propositions about the ""distribution of electricity"" on conducting bodies. Of Coulomb, who had never written like Poisson of the ""thickness"" of the electrical layer, Thomson said that he had ""expressed his theory in such a manner that it can only be attacked in the way of proving his experimental results to be inaccurate."" He did not, therefore, believe that Coulomb's approach would stand or fall with the fate of the electrical fluid.Of course, it may be wondered how Thomson could have employed the phrase ""distribution of electricity"" without believing that some hypothetical entity is implicated. He did not think so, however. Instead, by 1845 he was drawing a distinction between a ""physical hypothesis"" and an elementary mathematical law."" By a physical hypothesis he meant an assumption concerning the physical existence of an unobservable entity like the electrical fluid or Faraday's contiguous dielectric particles. By an elementary mathematical law he meant a statement that can be directly applied in experiments because its referents are phenomenal entities and mathematical propositions about them. For example, when it is a question of the ""distribution of electricity"" a phrase that might appear in an ""elementary mathematical law,"" the actual subject concerns the effects produced when a proof-plane is applied to a point of an electrified conductor. The measure of those effects is the twist given to the torsion-bearing thread of an electrometer. Coulomb's laws, therefore, and also those aspects of Poisson's mathematical development of them that do not depend upon the conception of electricity as a physical fluid, were thus actually concise, mathematical laws applicable to the results of such experiments. They were not hypotheses concerning the nature of electricity."" (DSB)‎

‎First printing. The focusing ability of a lens or mirror type antenna is directly related to its width in wavelengths of the radar wave. The wider the antenna is in wavelengths, the smaller the angle of the beam that contains 50% of the radiated energy. The smaller the angle of the beam, the farther the radar can see the target and the more precisely the angle of the target can be known. Nike tracking radars had an effective antenna width of about 150 wavelengths. (The antennas were actually physically a little larger, but there are edge effects which decrease the focusing effect of the edge areas.)‎

Today the equation is used in magnetic resonance imaging (MRI), a method that produces images of biological tissues weighted with the local micro-structural characteristics of water diffusion.
