Thomas noted that earlier calculations of the precession of the electronic spin had been performed in the rest frame of the electron, without taking into account the precession of the electron orbit around its normal. Inclusion of this relativistic effect reduces the angular velocity of the electron (as seen by the nucleus) by the needed factor 1/2. Einstein was surprised. Pauli became converted.""

‎First appearance of these two historical papers in chemistry in which Thomson and Wollaston, independently, presents experimental proofs of John Dalton's ""Law of Multiple Proportions"", and thereby laying the foundations of the Atomic Theory. - These demonstrations went far to influence chemists favorably toward Dalton's atomic theory. ""In January 1808 Thomson was the first to submit an experimental illustration of the law of multiple proportions, doing so at least four months before the publication of Dalton's ""New System of Chemistry Philosophy"" (1808). This paper, ""On Oxalic Acid"" also established a usefull method of determining empirical formulas.""(DSB XIII, p. 373).""This paper is also importent as he here introduces quantified chemical symbolism for compounds, a compound with, for instance, two parts oxygen (w) and one part carbon (c) being denoted by 2w + c."" (Parkinson in ""Breakthroughs"", 1808 C).""In 1808 he (Wollaston) described his experiments on carbonates, sulfates, and oxalates, which proved that the composition of these substances was regulated by the law of multiple proportions. These additional instances of the law were easely verifiable and were often mentioned as standard examples. Wollaston accepted that his findings were merely particular instances of Dalton's assertion that the atoms of elements united one to one, or by simple multiple relation.""(DSB XIV, p.488).‎

‎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.‎

‎First appearance of Tschirnhaus's three exceedingly important papers which were to to initiate one of the most famous mathematical discoveries. In the papers he used infinitisimal methods which were very close to Leibniz's method and where he tried to lay down criteria for rational quadratures in the case of conic, cubic and quadratic curves, papers that led Leibniz to publish his first paper on the differential calculus, the ""Nova Methoda"" in the Acta for 1684 in order to secure his priority over Tschirnhaus concerning the calculus. Leibniz discovered, when he read Tschirnhaus' papers, that Tschirnhaus had here published results showing similarity with Leibniz's invention of the calculus as he had confided to Tschirnhaus earlier, during their Parisian stay, and this without references to Leibniz.The present volume of Acta also contain the first edition of Tschirnhaus' ""Tschirnhaus Tranformation"". Tschirnhaus work intensively on finding a general method for solving equations of higher of higher degree. ""His transformations constituted the most promising contribution to the solution of equations during the seventeenth century" but his elimination of the second and third coefficients by means of such transformation was far from adequate for the solution of the quintic.(Boyer. A History of Mathematics, 1968, 472 p.).Tschirnhaus (1651-1708) , a Saxon nobleman, had as wide interest as acquaintances: He studied in Leyden, served in the Dutch army, visited England and Paris several times. He set up a glassworks in Italy and is said to have introduced Porcelain to Europe. He wrote about philosophy and mathematics and was a close friend of Leibniz.‎

(Fourcroy). ""In 1750 Venel described his analysis of the effervescent mineral water of Selz, in Germany. Evaporation yielded only common salt and a little lime, and he was more interested in the effervescence, which was, he thought, caused by the escape of common air. All water contained a small amount of dissolved air, but Selzer and other effervescent waters contained superabundant air, as Venel called it. He made artificial Selzer water by adding the correct amounts of marine (hydrochloric) acid and soda to pure water, and he called the product aerated water, a term that is still in use. Stephen Hales had thought that effervescent mineral waters contained “sulphurous spirit"""" Venel’s experiments proved the absence of the gas now called sulfur dioxide, but he failed to notice that the ""superabundant air"" differed in any way from common air. It was, of course, carbon dioxide, characterized in 1754 by Joseph Black, who called it fixed air.

Von Neumann showed that mathematical rigor could be restored by taking as basic axioms the assumptions that the states of a physical system were poinds of a Hilbert space and that the measurable quantities were Hermitian (generally unbounded) operators densely efined in that space.

‎First edition of this important first systematical treatment of the theory of complex numbers and at the same time, the first work to add vectors in three-dimensional space.""Wessel’s fame as a mathematician is based entirely on one paper, written in Danish and published in the Mémoires of the Royal Danish Academy, that established his priority in publication of the geometric representation of complex numbers. John Wallis had given a geometric representation of the complex roots of quadratic equations in 1685"" Gauss had had the idea as early as 1799 but did not explicitly publish it until 1831. Robert Argand’s independent publication in 1806 must be credited as the source of this concept in modern mathematics because Wessel’s work remained essentially unknown until 1895, when its significance was pointed out by Christian Juel. The title of Wessel’s treatise calls it an ""attempt"" to give an analytic representation of both distance and direction that could be used to solve plane and spherical polygons. The connection of this goal with Wessel’s work as a surveyor and cartographer is obvious. The statement of the problem also suggests that Wessel should be credited with an early formulation of vector addition. In fact, Michael J. Crowe, in A History of Vector Analysis (University of Notre Dame Press, 1967), defines the first period in that history as that of a search for hypercomplex numbers to be used in space analysis and dates it from the time of Wessel, whom he calls the first to add vectors in three-dimensional space.""

‎First appearance of this importent paper in which Whewell gave crystallography a mathematical foundation.""In a paper read before the Royal Society in 1824, Whewell, according to Herbert Deas, ""laid the foundations of mathematical crystallography."" His system for calculating the angles of planes of crystals assumed that crystals are aggregates of small rhomboids that can be thought to shrink below the level of possible measurement, thus suggesting that crystals are latticelike. In 1825 Whewell visited Mohs in Germany. In 1828, the year in which Whewell became professor of mineralogy, he published a revision of Mohs’s system of mineralogical classification.""(DSB).‎
