‎First appearance of Dufay's importent work on phosphorescence.""Chemists had long been acquainted with a fes minerals like the Bologna stone (BaS) and Balduin's hermetic phosphor (plain CaS) that glowed after exposure to light. Greatmystery surrunded those expensive and supposedly rare substances. Dufay detested mysteries and held as a guiding principle that a given physical property, however bizarre, must be assumed characteristic of a large class of bodies, not of isolated species. He found that almost everything except metals and very hard gems could be made phosphorescent: he depressed the phosphor market by describing his procedure: and he became sensitive to the endless small variations in the physical properties of bodies. 'How many things behave that seemed similar, and how many varieties there are in effects that seemed identical.""

‎First publication of these two seminal papers which constitutes one of the most significant discovery in 20th century physics. It ushered a golden period of low-temperature physics and created a new research field within physics which was later to be called quantum liquids. Both paper described a hitherto unknown state of matter: superfluidity of matter. The two discoveries were made independently, Kapitza's paper superseding Allen and Misener's by two weeks. Both studies reported that liquid helium flowed with almost no measurable viscosity below the transition temperature of 2.18 K.""Although the discovery of superfluidity stands as one of the most significant in physics in the 20th century, it was to be 40 years before the Royal Swedish Academy of Sciences honoured this seminal discovery with a Nobel prize - an exceptionally long interval. In 1978 Kapitza, by then 84, was given half of that year's Nobel Prize for Physics with a somewhat vague citation reading ""for his basic inventions and discoveries in the area of low-temperature physics"". The other half did not go to Allen and Misener. Today, science popularizers generally give sole credit for the discovery of superfluidity to Kapitza."" (Physics world, University of Toronto.). ""Kapitza observed that He II flowed between two closely spaced parallel plates extremely rapidly compared to He I, for the same pressure difference. This result, published in Nature on 8 January 1938, showed unambiguously that here was a new and mysterious kind of liquid - one with almost no viscosity. On the page facing Kapitza's one-page paper was another by the young Canadian physicists Jack Allen and Donald Misener, with essentially equivalent results on helium flow on long capillary tubes. It was submitted two weeks after Kapitza's, but both papers are the standard reference for the discovery of superfluidity"". (Griffin, A Century of Nature, 2003, p. 52).While investigating the thermal conductivity of liquid helium, Kapitsa measured the flow as the fluid flows through a gap between two discs into a surrounding bath. Above the lambda point, there was little flow, but below the lambda temperature, the liquid flowed with such great ease that Kapitsa drew an analogy with superconductors. It was a liquid of zero viscosity. He discovered the phenomenon in 1937 and published a paper about it in Nature in January 1938. He wrote: ""The helium below the lambda point enters a special state that might be called a ‘superfluid.’"" (DSB).Today the theory behind superfluidity is widely used within a broad variety of different subject such as spectroscopic and in high-precision devices as gyroscopes which allow the measurement of some theoretically predicted gravitational effects. In 1999, a type of superfluid was used to trap light and greatly reduce its speed. Light was passed through a Bose-Einstein condensed gas of sodium (superfluid) and found to be slowed to 17 m/s from its normal speed of 299,792,458 metres per second.Brandt, The Harvest of a Century, Pp. 254-7.‎

As a result of the work of Soddy and Aston a new form of Prout's hypothesis was established and Prout was found to be not wrong, but merely a century premature.""(Asimov).""The concept of a primary substance as the basis of all matter has a tempting simplicity which has appealed to thinkers from the classic Greek age to our own day. The idea was revived in a new garb in 1815-1816 by a London physician, Willia Prout, who observed that with few exceptions the specific gravities of elementary gases (i.e., their atomic weight) were evenmultiples of of that of hydrogen. The experimental errors in the data then available were such asto make the hypothesis appear plausible. Prout concluded, therefore, that hydrogen isthe fundamental constituent from which all other elements are compounded....... his idea that all matter is composed of the same material is now established.""(Leicester & Klickstein in ""A Source Book in Chemistry 1400-1900"", p. 275 ff.). - See also note to PMM 407, entry Moseley The Atomic Table.Parkinson ""Breakthroughs"", 1816 C.‎

In 1857, Henri Deville began a eries of studies which established quantitatively a new type of high- temperature reaction... In the course of his studies on the preparation of sodium and potassium and their use as reducing agents in the manufacture of other metals, Deville often used high temperatures. He was aware of the decompositions which often occurred under these conditions, and he suspected that such decompositions were of very frequent occurrence. He therfore undertook the study of reactions which occurred reversibly at high temperature. Such reactions he called 'dissociations', and by an extensive series of studies he showed the importence of dissociation as a general phenomenon in chemistry."" (Leicester a.

‎First edition, off-print, of the seminal paper that contains the first enunciation of the thermochemical affinity principle and the introduction of the term ""varmetoning"". The present paper represents Thomsen's main work as well as the ""(to use Oswald's words) scientific creed of the chemist for the next half-century. It constituted the only method by which chemists could predict the course of chemical reactions, and Thomsen himself employed the theory in various ways to carry out calculations of this kind."" (Brøndsted in: Meisen edt., Prominent Danish Scientists Through the Ages, p. 143). This breakthrough work, which contains the first statement of a thermochemical nomenclatura and the first definition and presentation of the thermochemical affinity principle, inaugurated a several decades long period of thermochemical studies, during which Thomsen personally carried out more than 3,500 calorimetric measurements in a room kept at 18 degrees celcius. His fundamental thought was that the evolution of heat accompanying a chemical reaction (""varmetoning"") is an exact expression of the chemical affinity of the reaction. Bethelot reached many of the same conclusions a bit later and advanced a theory that in essence was the same as Thomsen's. This led to heated discussions that continued for several years between the two scientists. Thomsen's principle is now usually known as the Thomsen-Berthelot-Principle. In 1883, the Davy Medal was awarded in duplicate, to ""M. Marcellin Berthelot, Member of the Institute of France, and Foreign Member of the Royal Society, and Prof. Julius Thomsen, of Copenhagen"", although Berthelot was obviously preceded by Thomsen. ""The importance of Thomsen's scientific work was rapidly recognized in both Denmark and abroad. In 1860 he was elected member of the Royal Danish Academy of Sciences and Letters. Nine years later he was nominated as professor of physical chemistry at the University of Leipzig, but he refused the offer. Many foreign scientists asked to work under his guidance, but he was afraid that the comparability of the results obtained would be endangered when more than one person performed such measurements and therefore refused all such requests. Thus no school was formed around him. Thomsen was a foreign member of various academies and honorary member of learned societies, and held honorary doctorates from several universities (but not in France, because of the conflict with Berthelot)."" (D.S.B. XIII:359).""Julius Thomsen's international reputation is due largely to his thermochemical studies. He began to work on thermochemical problems in 1850, and in 1852 he published in the ""Videnskabernes Selskabs Skrifter"" a paper entitled ""Bidrag til et thermochemisk System"" [""Contributions to a thermochemical System""], in which he outlined the scheme of his subsequent thorough investigations in this field. This paper contains the first enunciation of the thermochemical affinity principle, which states that chemical affinity, or the attraction between substances, can be measured by the heat evolved when they combine.Ideas as to the nature and laws of chemical affinity were by no means lacking at this period, but the prevalent views were vague, hypothetical and mutually irreconcilable. The great importance of Julius Thomsen's principle when compared with earlier speculations lies not only in its fundamental theoretical ideas, which associate chemical and mechanical phenomena, but also in the fact that the conception of affinity is related to a measurable quantity, the ""Varmetoning"" - a term which Julius Thomsen introduced to include both evolution and absorption of heat - and thus is easily accessible to experimental investigation.""

Following Galvani's experiments and the discovery of the voltaic pile, interest in galvanic electricity had become widespread. The first electrolysis by means of the pile was carried out in 1800 by Nicholson and Carisle, who obtained oxygen and hydrogen from water. Davy began to examine the chemical effects of electricity in 1800, and his numerous discoveries were presented in his Bakerian lecture to the Royal Society on November 20, 1806 (the paper offered here).

He published 30 papers in all under this general title.They represents Faraday's most importent work, are classics in both chemistry and physics and are the experimental foundations for Maxwell's electro-magnetic theory of light, using Faraday's concepts of lines of force or tubes of magnetic and electrical forces. His many experiments on the effects of electricity and magnetism presented in these papers lead to the fundamental discoveries of 'induced electricity' (the Farday current), the electronic state of matter, the identity of electricity from different sources, equivalents in electro-chemical decomposition, electrostatic induction, hydro-electricity, diamagnetism, relation of gravity to electricity, atmospheric magnetism and many other.""Among experimental philosophers Faraday holds by universal consent the foremost place. The memoirs in which his discoveries are enshrined will never ceaseto be read with admiration and delight"" and future generations will preserve with an affection not less enduring the personal records and familiar letters, which recall the memory of his humble and unselfish spirit.""(Edmund Whittaker in A History of the Theories of Aether and Electricity).The paper is reprinted in Magie: A Source Book in Physics p.485 ff.‎

He further utilized the strong reducing power of potassium to prepare boron.""Humphry Davy was one of the most brilliant chemists of the early nineteenth century. His early study of nitrous oxide brought him his first reputation, but his later and most importent investigations were devoted to electrochemistry. Following Galvani's experiments and the discovery of the voltaic pile, interest in galvanic electricity had become widespread. The first electrolysis by means of the pile was carried out in 1800 by Nicholson and Carisle, who obtained oxygen and hydrogen from water. Davy began to examine the chemical effects of electricity in 1800, and his numerous discoveries were presented in his Bakerian lectures."" - Not in Wheeler Gift. - The Ronalds Library p. 128.‎

‎First appearance of the paper in which Wollaston announced his discovery of the metallic element Rhodium.""Dr. Wollaston dissolved a portion of crude platinum in qgua regia, and neutralized the excess acid with caustic soda. He then added salammoniac to precipitate the platinum as ammonium chloroplatinate, and mercurous cyanide to precipitate the palladium as palladium cyanide. After filteringoff the precipitate, he decomposed the excess mercurous cyanide inthe filtarate by adding hydrochloric acid and evaporating to dryness. When he washed the residue with alcohol, everything dissolved except a beautiful dark red powder, which proved to be a double chloride of sodium and a new metal, which because of the rose color of its salts, Dr. Wollaston named 'Rhodium'. He found that the sodium rhodium chloride could be easely reduced by heating it in a current of hydrogen, and that after the sodium chloride had been washed out, the rhodium remained as a metallic powder. he also succeeded in obtaining a rhodium button.""(Weeks: Discovery of the Elements. p. 104-05.)‎
