‎Copenhagen. 1850. 4to. Uncut and unopened. No wrappers. Plates loose. Very nice and clean. Pp. (121) - 188 + four plates.‎

‎First edition of these absolutely fundamental papers, by the (co-)discoverer of the principle of Conservation of Energy, prove Colding's assumption of ""the imperishability of nature"" and present for the first time in printing his elaborate experiments on the subject, contributing significantly to the cementation of his version of the principle of Conservation of Energy. Ludvig August Colding (1815 - 1888) was a famous Danish engineer and physicist. He was originally educated as a carpenter but graduated as mechanical engineer in 1841. In 1845 he became water-inspector in Copenhagen and in 1847 he was also given the responsibility of the gas- and waterworks. Together with the famous chemist Julius Thomsen, he proved that the cholera spread throughout Copenhagen through the drinking water (1853) - a most significant discovery. After this he was responsible replacing much of the sewer-system of Copenhagen. In 1857 he became state engineer. During this period he overhauled the desperately inadequate water and sanitation system. He articulated the principle of conservation of energy contemporaneously with, and independently of, James Prescott Joule and Julius Robert von Mayer though his contribution was largely overlooked and neglected.His work on the power of water-stem in the steam engine is considered one of his most significant.The principle of Conservation of Energy was discovered and proven independently and practically simultaneously by Colding, Meyer, Joule, and Helmholtz. As the other three, Colding had discovered the principle in the early 1840'ies, but up until 1843 (where he publishes his first breakthrough article on the subject), Colding's experiments had suggested that no force seems to be disappearing but merely undergoes a transformation, whereupon it becomes effective in other forms. On H.C. Oersted's recommendation (Colding was Oersted's assistent in their experiments with the heating of compressed water), however, Colding carried out a more elaborate version of his experiments, which made him able to verify his assumption that led to his principle of Conservation of Energy with much greater certainty. These new results were reported at the 1847 meeting of Scandinavian Scientists and published in 1850 as the two first papers present here.Mayer's famous ""Bemerkungen über das mechanische Aequivalent der Wärme"" was published a year after Colding's papers, 1851.‎

‎Rare first edition, presentation-copy, of colding's highly interesting first work on the philosophical and religious aspects of his discovery of the principle of conservation of energy, which is of importance for his discussions of joule's experiments and for his priority dispute with mayer, independently of and simultaneusly with both of whom he discovered the principle of conservation of energy. Presentation inscription from the author (""Hr. Generalmajor v. Schlegel / ærbødigt fra A. Colding"") [i. e. ""Mr. General Major v. Schlegel / Yours faithfully A. Colding""] to verso of the original front wrapper.Ludvig August Colding (1815 - 1888) was a famous Danish engineer and physicist. He was originally educated as a carpenter but graduated as mechanical engineer in 1841. In 1845 he became water-inspector in Copenhagen and in 1847 he was also given the responsibility of the gas- and waterworks. Together with the famous chemist Julius Thomsen, he proved that the cholera spread throughout Copenhagen through the drinking water (1853) - a most significant discovery. After this he was responsible for replacing much of the sewer-system of Copenhagen. In 1857 he became state engineer. During this period he overhauled the desperately inadequate water and sanitation system. He articulated the principle of conservation of energy contemporaneously with, and independently of, James Prescott Joule and Julius Robert von Mayer though his contribution was largely overlooked and neglected.""The Philosophical and religious side of Colding's thesis was first elaborated in his cumbersome treatise of 1856, ""Naturvidenskabelige Betragtninger over Slaegtskabet mellem det aandelige Livs Virksomheder og de almindelige Naturkraefter"" (""Scientific Reflections on the Relationship between the Intellectual Life's Activity and the General Forces of Nature""), his last paper on this topic to the Danish Society of Sciences"" it was published on the occasion of his being elected member of the Society. It stressed his own philosophical conviction and dwelt at length on the relationship between the material and the spiritual in nature, clearly echoing the intellectual and aesthetic influence of Oersted and in a tone reminiscent of Kant and Schelling. This paper is also of interest for Colding's discussions of Joule's experiments, with which he was acquainted by then, and for his passionate priority dispute with Mayer.""

‎Rare first edition, presentation-copy ""fra Forfatter"" [i.e. from the author] on front wrapper, of Colding's observations concerning dampness in Copenhagen and surroundings.The present work is based on Colding's experiences and observations during his years as state-engineer. The water supply in Copenhagen was largely built upon the accumulation on the thaw drain in spring, hence his studies on evaporation in lake Peblinge and lake Damhus in Copenhagen. During the 1850' ies Colding initiated drillings in the catchment area of lake Damhus. These drillings created the foundations for The Copenhagen Waterworks.

‎First edition, off-print (separately paginated), presentation-copy, of Colding's major contribution to the development of the steam engine. The hand-written presentation on front free end-paper reads as thus: ""Høivelbaarne/ Hr. General-Major Schlegel C. af D. pp./ med høiagtelse/ fra/ Forfatteren."" [Honoured/ Mr. General v. Schlegel C. of D. pp. (honorary title)/ with high estimation/ from/ the author.].Ludvig August Colding is primarily remembered today for, together with Meyer, Joule, and Helmholtz, having determined the principle of Conservation of Energy. His final major contribution to this discovery consists in the publication of his elaborated experiments which once and for all determined the accuracy of his assumption (that no amount of energy gets lost, since what is apparently lost in energy will be found in other places or in different forms, e.g. heat) (1850). Two years after that seminal publication, he publishes his main contribution to the development of the steam engine, namely his ""Investigation of the Water Steams and their Moving Power in the Steam Engine"" (1850), which is obviously based on his determination of the principle of conservation and alteration of energy.Colding was a famous Danish engineer and physicist. He was originally educated as a carpenter but graduated as mechanical engineer in 1841.

‎First appearance of this important issue of The Royal Danish Academy of Sciences and Letters' Journal containing some of the most influential Danish contributions to science from the period: - Thomsen's ""Bidrag til et thermochemisk System"" undoubtly being the main contribution by a Dane in chemistry in the 19th Century.The paper from 1852 is famous as it is the first statement of a new thermochemical nomenclatura, and the 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 bodies combine. His fundamental thought was that the evolution of heat accompanying a chemical reaction (which he calls 'varmetoning', equivalent to enthalpy change) is an exact expression of the chemical affinity of the reaction.- Colding's ""Undersøgelse over Vanddampene og deres bevægende Kraft i Dampmaskinen"" being his major contribution to the development of the steam engine. ‎

‎First edition, off-print (separately paginated), of Colding's contribution to water level in loops with constant water flow.His works with the construction of sewers were the cause of his studies of water movement in closed loops. This led him to the realization of the variation of the coefficient of resistance with flow velocity, a similar result reached by Julius Weisbach. While studying these topics he founded the principles which the later constructed sewage system in Copenhagen was based upon. He expanded the use of these studies to also encompass studies of the free water table forms and currents in the ocean. Ludvig August Colding (1815 - 1888) was a famous Danish engineer and physicist.
