‎First appearance of Thomson's second paper on the Vortex Atom. In 1882 he had won a prize with the subject ""a general investigation of the action upon each other of two closed vortices in a perfect incompressible fluid""The first attempt to construct a physical model of an atom was made by Lord Kelvin in 1867. The main point was that in an ideal fluid, a vortex line is always composed of the same particles, it remains unbroken, so it is ring-like.""In fact, the investigations of vortices, trying to match their properties with those of atoms, led to a much better understanding of the hydrodynamics of vortices - the constancy of the circulation around a vortex, for example, is known as Kelvin's law. In 1882 another Thomson, J. J., won a prize for an essay on vortex atoms, and how they might interact chemically. After that, though, interest began to wane - Kelvin himself began to doubt that his model really had much to do with atoms, and when the electron was discovered by J. J. in 1897, and was clearly a component of all atoms, different kinds of non-vortex atomic models evolved.""(Michael Fowler).‎

‎First appearance of all the 6 founding papers around the invention of the ""Harmonic Analyzer"" and with the mathematical theory for the differential analyzor, containing both the mathematical theories and the practical descriptions of the analyzer and further also having the paper by Lord Kelvin's brother (the first paper offered) in which the machinery is shown for the first time.""A ball and disk integrator was the vital invention needed to build the FIRST AUTOMATIC ANALOG COMPUTING MACHINES. Lord kelvin used this integrator -devised for a planimeter in the 1860s by his brother, James Thomson - on two new kinds of analog computers: a harmonic analyzer and a tide predictor. he later specified a more general machine - a differential analyzer.""(Eames in ""A Computer Perspective"").""The harmonic analyzer was used in conjunction with Thomson's tide predictor...The present paper (""Harmonic Analyzer"") contains the first full description of the harmoniz analyzer, which was ""designed rudimentally"" (p. 371) in Thomson's ""On an integrating machine having a new kinematic principle""(also offered here),,,,James Thomson's integrator - ""one of the first really workable integrating devices"" (Williams 1985, 207) - served as the basis for other analog machines designed by William Thomson for solving simultaneous linear equations and integrating differential equations. Thomson first described such a machine, composed of several Thomson integrators connedted together, in his paper on ""Mechanical integration of the linear differentialequations of the decond order...."" (also offred here)"" however the ""idea could then hardly be carried out, forone reason because an integrator, which is simply a variable- speed drive, could not then be buitl both accurate and capable of carrying sufficient load to move numerous mechanical parts"" (Bush 193, 450). The full realization of Thomson's idea did not come until fifty years later, when Vannevar Bush invented the torque amplifier for use in his differential analyzer.""(Hook and Norman).‎

‎First printing of these importent papers in which the authors found the so-called Joule-Thomson effect which should be the founding technology in refrigeration. They showed that a gas expanding into vacuum without addition of external work undergo a change in temperature, in spite of the theoretical speculations. The temperature change occurs due to the internal work required to overcome the attractive forces between molecules.""The only substantial contribution to thermodnamics to which the joint names of Joule and Thomson, are attached belongs to an idea conceived by Thomson, who saw the possibility of analyzing the deviations of gas properties from the ideal behavior. 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 a cooling (essentially a transformation of atomic motion into work spent against the interatomic attractions). For the delicate test of this effect Thomson required Joule’s unsurpassed skill (1852). But the application of the Joule- Thomson effect to the technology of refrigeration belongs to a later stage in the development of thermodynamics.""(DSB).Peter Guthrie Tait (1831 - 1901) was a Scottish mathematical physicist, best known for the seminal energy physics textbook Treatise on Natural Philosophy, which he co-wrote with Kelvin, and his early investigations into knot theory, which contributed to the eventual formation of topology as a mathematical discipline. His name is known in graph theory mainly for Tait's conjecture. (His name on the first titlepage).Parkinson ""Breakthroughs"" 1852 C.‎

‎First appearance of this highly importent paper in the development of thermodynamics, describing the experiments leading to the discovery of the cooling effect when a gas is allowed to expand freely. This is the founding theory, later used in refrigeration.""The only substantial contribution to thermodynamics to which the joint names of Joule and Thomson are attached belongs to an idea conceived by Thomson, who saw the possibility of analyzing the deviations of gas properties from the ideal behavior. 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. ‎
