‎Firs appearance of these two milestone papers in nuclear physics recording the set up of the first proton accelerator and describing the first nuclear reaction brought about artificially. the first paper describing the sccelarator, the second the nuclear reaction. their experiment with the accelerator is regarded as the first demonstration of the mass-energy equivalence. cockcroft and walton were awarded the nobel prize in 1951.""Cockcroft, with the assistance of Walton, devised aninstrument in 1929 that could built up voltages(a voltage multiplier) and, in so doing, accelerate protons (which are easy to obtain by ionizing hydrogen atoms) to energies higher than those of natural alpha particles. In 1932 Cockcroft and Walton mbombarded lithium with such protons and produced alpha particles. It was clear, that what they had done was to combine lithium and hydrogen to form helium. This was the first nuclear reaction brought about through artificially accelerated particles and wihtout the aid of any form of natural activity....Both during and after World War II, Cockcroft was engaged in work having to do with the development of the atomic bomb. And, as it happened, his very first artificially-induced nuclear reaction, that of lithium with hydrogen, proved to be of GREAT IMPORTENCE IN THE DEVELOPMENT OF THE HYDROGEN BOMB.""(Asimov).Sigmund Brandt ""The Harvest of as Century"", Episode 50.‎

‎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. 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. ‎

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 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.""
