‎First appearance of the 2 papers which represents Homberg's main works. In these papers he shows for the first time how to determine equal weights of substances, that all acids differ only in water content, and that dry acids combines in equal proportions with alkali. In the first paper he also gives the Pygnometer Bottle its modern form.""Probably his most importent work was on the strenght of acids and the quantity required to neutralize a given quantity of alkali (two papers published in 1699 and 1700) - the papers offered - Homberg recognized that different alkalis neutralized the same acid in different proportion but believed that the relative strenghts of two acids could be determined by using the same alkali in each case. he treated the the question of neutralization (or dissolvability, as he called it) in quite quantitative fashion, showing that if an alkaline salt were treated with an acid, the gain of weight ofthe salt wasan indication of the amount of acid absorbed....Homberg nevertheless understood the fundamentals of the process and thereby laid the foundation for an understanding the nature of salts.""(DSB VI, p. 478).Parkinson ""Breakthroughs"" 1700 C.‎

‎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.‎

‎First appearance of this milestone paper in organic chemistry in which he demonstrated the mutual linking together of carbon atoms, developed the idea of affinity units, later called ""valence bonds"", and thus making it possible to explain the formation of organic compounds containing large numbers of carbon atoms. This was ""the final step in the development of modern structural formulas for organic compounds..."" (Leicester & Klickstein, p. 417)""It was not till 1858 that a satisfactory theory of molecular constitution was advanced, simultaneously and independently, 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 means 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. - Ostwald's Klassiker No. 183. - Leicester & Klickstein ""A Source Book in Chemistry"", pp. 417-425. - Exhibition of First Editions of Epochal Achievements in the History of Science, Berkeley 1934.

‎First edition of the first volume of this very important journal, founded by Lavoisier and his friends, collaborating in establishing THE NEW SCIENCE of Anti-Phlogistic theory in chemistry. Crosland (in ""The two French Revolutions"" and ""The Imperial Despotism of Oxygen"") claims that for a clear understanding of the CHEMICAL REVOLUTION, THE NEW JOURNAL of ANNALES DE CHIMIE can be rightly considered as FUNDAMENTAL as the ""Traite élementaire de Chimie"".""A third and most important instrument was the establishment of a new scientific journal, edited - and dominated - by the votaries of the ""new chemistry"". The first number of this journal of the Annales de chimie appeared in 1789, the year of the Revolution. Its editors were besides Lavoisier, his early disciples - Guyton, Berthollet, Fourcroy, and Monge - with the addition of three new recruits: the Strassbourf metallurgist the Baron de Dietrich, Jean-henri Hssenfratz and Pierre Auguste Adet.""(DSB VIII, p.81).LAVOISIER'S paper on COMBUSTION (pp. 19-30) contains his important interpretation of the phenomena of combustion in air, making the fundamental distinction between burning and combustion. By this ""Lavoisier gave to the study of chemistry a new life, a new direction and a wider outlook."" (Alexander Findley).""The Lavoisierian memoir on combustion of iron stood out among the large number of interesting papers discussed in the first volume of the ""Annales"". In his account Lavoisier sustained that in nature, combustion without flames did occur. Thus, he clarified the distinction between ordinary burning and combustion: an issue on which the majority of traditional chemists were confused. The need for accuracy and precision in laboratory practices was emphasised in his study, as it was a means to determine quantities rather than assuming them.""(Angela Bandinelli in ""Scientific Communication During a Major Change ...Empirical Research: Annales de chimie vs Obs. sur la physique/ Journal de physique (1789-1803)).The volume furthermore contains important papers by: Adet, Fourcroy (3 papers), Berthollet (3 papers), Chaptal, Hassenfratz (5 papers), Baron de Dietrich (2 papers), Klaproth (2 papers), Girtanner, Dollfuss, Bonz de Ettingen, Crell, De Morveau.‎
