‎First appearance of an importent papwer in the history of analytic geometry.""In this article Tinseau gave an interesting generalization of the Pythagorean theorem for space of three dimensions: the square of the area of a plane surface is equal to the sum of the squares of the projection of this surface upon three mutually perpendicular coordinate planes....To Tinseau it appears that the use of the word ""conoid"" in the modern sense is due.""(Boyer ""History of Analytic Geometry, p. 207).""Two of the three memoirs that constitute Tinseau’s oeuvre deal with topics in the theory of surfaces and curves of double curvature: planes tangent to a surface, contact curves of circumscribed cones or cylinders, various surfaces attached to a space curve, the determination of the osculatory plane at a point of a space curve, problems of quadrature and cubature involving ruled surfaces, the study of the properties of certain special ruled surfaces (particularly conoids), and various results in the analytic geometry of space. In these two papers the equation of the tangent plane at a point of a surface was first worked out in detail (the equation had been known since Parent), methods of descriptive geometry were used in determining the perpendicular common to two straight lines in space, and the Pythagorean theorem was generalized to space (the square of a plane area is equal to the sum of the squares of the projections of this area on mutually perpendicular planes). (DSB). Although Tinseau published very little, his papers are of great interest as additions to Monge’s earliest works. Indeed, Tinseau appears to have been Monge’s first disciple.‎

[Entire volume: (8), 561, (7) pp + 13 plates].‎

‎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.‎

‎First printing of the papers in which Vauquelin describes and announces his discovery of Chromium. The first paper was simultaneously printed in Mem.de l'Institut. Because of its many coloured compounds Fourcroy and Haüy suggested the name 'chromium' for the new metal. (Greek, chroma-colour).In 1797, Vauquelin began his own studies of Siberian red lead. He was convinced that the mineral contained a new element. None of the elements then known could account for his results. He reported ""a new metal, possessing properties entirely unlike those of any other metal."" A year later, Vauquelin was able to isolate a small sample of the metal itself. He heated charcoal (nearly pure carbon ) with a compound of chromium, chromium trioxide (Cr 2 O 3 ). When the reaction was complete, he found tiny metallic needles of chromium metal.

‎In these two memoirs Venel attempted to prove that effervescent mineral waters contain a quantity of common air in solution, thus seperating carbon dioxyde (he called it air surabondante) without knowing what it really was, thus beeing ""so close to making a discovery without actually making it..."" (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. Fourcroy later commented that no one had ever been so close to making a discovery without actually making it as was Venel.""(DSB).‎

‎First French edition of these 3 letters to Gren in which Volta described his last steps towards his groundbreaking construction of his famous ""Pile"". In the letters he established the first law governing an electrical fluid and he anticipated both Davy and Faraday.""In 1796 Volta wrote three letters to Gren (published in German in Gren's N.J. der Physik). In THE FIRST he describes 'a very remarkable experiment'. A tin cup filled with soapy water, milk of lime, or better fairly strong alkaline ley, was held with one or both hands moistened witn ater, and the tip of the tongue dipped into the liquid. A sour taste was at once perceived by the tongue in contact with the alkaline liquid, which soon, changed into a salty and finally into a sharp alkaline taste. The acid taste was 'produced by the current of the electric fluid passing from the tin to thee alkaline liquer, from there to the tongue, then through the body to the layer of water and from there to the tin in a continous current..... In his SECOND LETTER Volta repeats this 'law' of the combination of three conductors. The mutual contact of silver and tin, for example, produces 'an action, a force, by means of which the first gives the electric fluid and the second receives it. If the circuit is completed by a humid concustor, a current or continous circulation of this fluid is set up in the direction indicated in the table (depicted on the attached plate)... In his THIRD LETTER Volta describes experiments in which plates of silver and zinc so smooth that they adhered on contact, polished, dry, and insulated, were brought in close contact, and separated by pulling them perpendicularly apart. They gave small deflections when applied directly to the electrometer...."" (Partington ""A History of Chemistry"", Vol. IV, pp. 10-12).‎

‎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.""

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 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 and Electricity."" II, p. 4).‎

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.""
