‎First appearance of both papers, controversial as Brodie here tries to established a new chemical philosophy, refusing atomism and founding the calculation of chemical processes on Boolean Algebra, defining chemical symbols with mathematical terms and notations. The work is a remarkable attempt to set chemistry on a rational deductive basis. - The introduction in the second paper meets the main points raised by his critics.""In 1866 the Royal Society began to publish Brodie’s ""The Calculus of Chemical Operations"" (Philosophical Transactions, 156 [1866], 781-859"" 167 [1877], 35-116) which introduced Greek symbols for the chemical elements to replace the roman alphabet (Berzelian) symbols that contemporary chemists used to represent atomic weights. Brodie’s symbols, however, represented operations on space (volumes), not weights for, besides its revolutionary symbolism, the calculus also demanded an appreciation of George Boole’s algebraic logic, which Brodie had studied after the publication of Boole’s Investigation of the Laws of Thought in 1854. In this an equation such as y = xy is a symbolic statement that y is a subset of x in which the symbol x is an operator on y. Although professional mathematicians like William Donkin and Henry Smith later advised Brodie, it appears that he developed the system without professional help. The principal difficulty about the calculus for the present-day historian and philosopher of science is the need to explain it before going on to discuss it and the difficulty of giving any concise description of it. Boole had developed the concept of symbolic operators in algebraic analysis. These provided a code as to how the symbols were to be understood and manipulated. Brodie exploited this in the idea of a chemical operator, or chemical operations, that he symbolized by Greek letters. It is probably unwise, therefore, to interpret Brodie’s philosophy as analogous to Percy Bridgman’s later operationism. He proposed that if two substances with the empirically-derived weights, x and y combined to form a new compound with weight xy, then x + y = xy. From such weight equations he constructed a symbolic algebra that bypassed any atomistic interpretation.""(William H. Brock in ""Hyle Biography"").‎

‎(London, Harrison and Sons, 1878). 4to. No wrappers as extracted from ""Philosophical Transactions"" 1877 - Vol. 167. Pp. 313-349.‎

‎First appearance of Adams and Day's landmark paper, in which they demonstrated that electricity could be produced from light without moving parts, eventually leading to the modern solar cell. It is here that Adams shows for the first time that the discovery of Willoughby Smith - that the conductivity of selenium is due only to the effect of light - is correct and furthermore that light has an effect on the resistance of selenium and that light generates electrical currents in selenium. Two years later Adams expanded the work and published 'Solar Heat'. Here he described his ""Power Tower Concept"", which to this day remains the basis of solar plants.William Grylls Adams (1836 - 1915), professor of Natural Philosophy at King's College, London, and brother of the famous astronomer John Couch Adams (1819-1892), was President of the Physical Society of London from 1878 to 1880. In 1872 he was elected a Fellow of the Royal Society and in 1875 delivered their Bakerian Lecture. He was president of the Institute of Electrical Engineers and of the mathematical and physical section of the British Association.His greatest achievement lies in demonstrating the seminal discovery that electricity could be produced from light without moving parts. The road to this discovery was begun in 1839 when Becquerel discovered that illumination of one of two metal plates in a dilute acid changed the electromotive force. Another French scientist, Auguste Mouchout, followed up on Becquerel's discovery, but it was not until 1876, when Adams and Richard Evans Day discovered that illuminating a junction between selenium and platinum has a photovoltaic effect, that the foundation for the documented use of solar thermal power was laid [with the publication of the present paper]. ""From a historical viewpoint, it is of interest to note that the first experiments on the generation of solar thermal power in India were conducted by an Englishman, William Adams, about one hundred years ago. Adams stayed in Coloba, Mumbai and performed his experiments in the compound of his bungalow. He used a sphecical reflector 12 m in diameter, made from sheets of glass mirror. The sun's rays were focussed on a boiler having a capacity of about 60 litres and the steam generated was used to drive a 2.5 HP steam pump. Adams's work is described in a book written by him entitled ""Solar Heat - A Substitute for Fuel in Tropical Countries for Heating Steam Boilers and Other Purposes"" (Education Society's Press, Byculla, Bombay, 1878)."" (Sukhatme & Neyak, ""Solar Energy. Principles of Thermal Collection and Storage"", p. 48)""William Grylls Adams was and English scientist who taught as a professor in the department of Natural Philosophy at King's College. He is notable for his contribution to the discovery of the photoelectric effect, on which all solar energy applications are based. He was inspired by Auguste Mouchout's invention of the solar steam engine. With the intent of making improvements to Mouchot's design, Adams began to experiment with different materials and designs. In 1876, working in conjunction with his student, Richard Day, he discovered that selenium produced electricity when exposed to sunlight. Using the selenium, he then added mirrors to the design to concentrate sunlight on the engine. This design came to be known as the power tower concept and is still in use today.""

Davy began to examine the chemical effects of electricity in 1800, and his numerous discoveries were presented in his Bakerian lectures."" Another notable paper comes together with avy's papers: THOMAS BRANDE ""The Bakerian Lecture: on some new Electro-chemical Phenomena. Read November 25, 1813.""

‎First appearance of this milestone paper in organic chemistry - a shorter note was published in Comptes Rendus in June 1858 - in which, independently of Kekulé, Couper introduces the CONCEPT OF BONDS (represented as a dash or a dotted line) in chemistry and also observes the very importent fact, that carbon atoms forms the backbone of organic compounds.""It was not till 1858 that a satisfactory theory of molecular constitution was advanced, simultaneously and endependently, by thwo young chemists, Friedrich August Kekulé and Archibald Scott Couper. The theory of molecular constitution put foreward....by Couper and Kekulé rested on two main postulates, the quadriivalency of carbon,....and the capacity of the carbon atom for mutual linking or combining together to form a carbon ""chain"". By this hypothesis of the mutual linking together of carbon atoms - which waslater confirmed by experiment - it was possible to explain the formation of organic compounds containing a large number of carbon atoms. On the foundation of their postulates two postulates, moreover, (they) showed how the molecular constitution or mutual linking together of the atoms of a compound could be represented diagrammatically and the relstions between different compounds made readily intelligible. In his classic paper ""On a New Chemical Theory"" (the paper offered here in its first appearance) advanced beyond Kekulé by representing the constitutions of the compounds by means of GRAPHIC FORMULA in which, as at the present day, the valencies pf the atoms are represented by lines....his formulae are similar to those at present in use...""(Findlay pp. 34 ff)""The theory of Kekulé and Couper gave the chemists the maeans of solving the problems of chemical constitution"" and by means of the graphic or constitutional formulae it became possible to represent the molecular constitution of known compounds and to foresee the possible existence of isomeric compounds.""(Findlay).Parkinson ""Breakthroughs"" 1858 C.The volume contains another importent, monumental memoir MARCELLIN BERTHELOT ""Sur la Synthèse des Carbures D'Hydrogene"", pp. 69-208. Here he prsents his review of his work in organic chemistry during the previous ten years. ""In his conclusion Berthelot argued that chemistry differed from a descriptive science such as natural history by being creative and that in this it resembled the mathematical sciences.""(DSB)‎

‎First appearance of a milestonepaper in chemistry in which Cailletet describes his invention of the liquedifaction-process of oxygen and 5 other gases - and a classic in Low-Temperature Chemistry.""Cailletet is most famous for his investigations on the compression and liquefaction of gases. At the time there were still six gases that were considered permanen: oxygen, nitrogen, hydrogen, nitrogen dioxyde, acrbon monooxide, and acetylene. Liquefaction had not been achieved despite the use of what were considered ernomous pressures. At the end of 1877 and the beginning of 1878 Callitet liquefied all these gases shortly before Raoul Pictet, who employed a completely different procedure. Cailletet had, following Andrews, recognized the importence of the critical temperature, above which liquefaction of a gas does not take place. In order to produce the necessary ccoling, he had recourse to expansion, sometimes employing several expansions in a staged process. It was in this manner that he succeeded in liquefying oxygen by beginning with liquid ethylene and passing through the stage of liquid methane.""(DSB III, pp. 11-12).

‎First appearance of a milestone paper in chemistry and physics in which the author describes how he found the new element Gallium by analyzing spectral lines which he observed on a Pyrenea blende sample, the emission lines corresponding to the eka-aluminum that was predicted by Mendeleev in 1871 and he subsequently isolated the element by electrolysis. This was the first element discovered by use of the spark spectrum. In his discovery of the new element Boisbaudran was not guided by the predictions of Mendeleev, but only by his own law of spectra.""Boisbaudran ranks with Bunsen, Kirchhoff, and Crookes as one of the founders of the science of spectroscopy.""(Weeks).""Lecoq de Boisbaudran announced his discovery (by spectroscopic analysis) of the new element gallium. Mendeleev had first predicted its existence and had named it eka-aluminium. The discovery was made in the author's private laboratory, in a specimen of zinc blende from the Pierrefitte mine in the Angelès Valley in the Hautes Pyrénées. He describes how on the evening of 27 August 1875 he detected the existence of this new element, which he named ""gallium"" in honor of France (Gallia). The plate shows the two spectral lines of gallium, which are distinct from those of other elements (indium and potassium) in the same region of the spectrum. A month later he ""performed in Wurtz's laboratory in Paris....a series of experiments to prove that gallium...is a true element""(Weeks). he discusses how he eventually isloated small amounts of pure metallic gallium and determined its physical and chemical properties. The paper (the paper offered) first describes gallium compounds (e.g., ammonium gallium alum,, chloride, oxide, and sulphate).""(Roy G.

‎First appearance of the paper in which Ramsay and Travers announced their discovery of a new element which they named ""krypton"" (meaning hidden).""Dr. William Hampson presented them (Ransay & Travers) with about a liter of liquid air, which they used, not for liquefying the argon, but for obstaining sufficient skill in manipulation so that they would not risk loosing their precious fifteen liter of argon......The residue left after most of the liquid air had boliled away consisted largly of oxygen and nitrogen, which Ramsay and Travers temoved with red-hot copper and magnesium. ....(they) then examined the twenty-five cibic centimeters of residual gas, and when they found it to be inerst, they immediately placedit in a Pl'ucker tube connected to and induction coil and observed its spectrum. There was a bright yelælow line with a greener tint than that of the helium line and a brilliant green line that did nor coincide with any line of argon, helium, mercury, or hydrogen. They discoverede this gas on 30 May, 1898, and named it 'krypton'....they found that it belonged between bromine and rubidium in the periodic table, and so great was their excitement that the younger chemist almost forgot about his examination for doctor of sciwence which had been schedules for the next day.""(Weeks, p. 267).Parkinson ""Breakthroughs"", 1898 C.‎
