2017ill., br. Ugo Ojetti (Roma 1871 - Firenze 1946) fu collezionista e opinionista sagace, ma fu, soprattutto, un raffinato censore del sistema delle arti italiano e, ancor più, un manager delle esposizioni, sorta di curatore ante litteram, teso fra passione antiquaria e ricerca di nuove qualità espressive, possibilmente connotate da un alto potenziale identitario ed economico. L'amore per i canoni visivi del nostro passato - avvertiti come necessaria consolazione al presente - lo spinse a promuoverne largamente il recupero, in una perenne ricerca di alleanze intellettuali, politiche e finanziarie. Opzione rischiosa, che lo portò - fra vittorie e delusioni - a incrociare i nodi più oscuri della programmazione culturale fascista. Questo volume indaga l'intensità del personaggio sotto il segno del fare. Segue il filo rosso della sua esperienza, affiancando scritti pubblici e carte private, così da individuare non soltanto il legame ch'egli seppe attivare fra indirizzo critico e attività organizzativa, ma anche la sua appassionata battaglia per avvicinare "la bellezza" a un pubblico esteso.

The entire issue No. 8 offered. Titlepage to vol. 26. Pp. 501-600. Helmholtz's paper: pp. 501-523. Clean and fine. First appearance of this founding paper in the modern theory of colour in which Helmholtz proved the surprising fact that there are only two among the colours of the spectrum yellow and indigo-blue which together yields pure white that is are complementary to each other whereas their combination had always been supposed to produce green."Helmholtz turned to the intricate problems of color vision in 1852 with an attack on Sir David Brewster's new theory of light. Brewster had maintained the objective reality of three primary colors by supposing in opposition to Newton that there exist three distinct kinds of light each of which excites in the eye one of the sensations red yellow or blue. Helmholtz regarded the theory as still another confusion of physical stimulus and subjective responce.He also revived Young's theory of color visoin.only to refute it. He had discovered that spectral colors when mixed always yield a duller color of less-than-spectral saturation. Therefore the whole idea that all colors may be obtained from mixtures of three primary colors must be incorrect he concluded for the spectral colorss at least can never be obtained in their full saturation by mixing any three of their number.Although Helmholtz dismissed Young's theory in 1852 by 1858 he had changed his mind and become its formost advocate. In order to save Ypoung's theory.Helmholtz asumed that Young's physiological primaries are not spectral colors att all but colors of far greater-than-spectral saturation."DSB VI pp. 246-247.

X636 pp. and 4 folded lithographed plates. Clausius's paper: pp. 239-258. The entire volume offered. Fine and clean. First printing of this main paper in the working out of the Kinetic Theory of Gases in which Clausius announced his determination of the equation governing the mean free path lenght of a molecule moving freely in gases. By this he inscribed his name as one of the founders of the Kinetic Theory of Gases."Clausius was one of the founders of the kinetic theory of gases and of the science of thermodynamics. He and Lord Kelvin at about the same time and independently announced the Second Law of thermodynamics. Clausius particularly developed the theory of thermodynamics by applying it to the study of gases and vapors."Magie in "A Source Book in Physics" p. 228."In order to analyze the process of molecular collisions Clausius adopted a simplified model for his admittedly complicated molecule. He assumed that whatever the actual patterns on intermolecular forces one could suppose that there is some advantage distance between the centers of molecules which would represent a general boundary between attractive and repulsive forces. If two molecules were to approach each other within that boundary repulsion would generally occur. Thus the very complex problem of intermolecular action was reduced to a "billiard ball" model."

First printing of this importent paper the seciond of C's papers in the working out of the Kinetic Theory of Gases. In the paper he states that he found an error in Maxwell's theory of gases an error Maxwell was to admit as far more serious. "In his initial approach to the conduction of heat in gases Maxwell drew a brilliant analogy between diffusion a transfer of mass and conduction a transfer of kinetic energy thereby making it possible to use the form of his diffusion equation to represent conduction simply replacing the mass of a molecule with its kinetic energy. Clausius critized this adoption of the diffusion equation because given the assumptions mass transfer would accompany the heat conduction and the process would not be one of energy transfer alone. He then offered a revised theory of conduction. "DSB III p. 308."Clausius was one of the founders of the kinetic theory of gases and of the science of thermodynamics. He and Lord Kelvin at about the same time and independently announced the Second Law of thermodynamics.

First German edition of both papers constituting the first 2 papers in his "Experimental Essays on the constitution of mixed gases." 1802 in which he formulated his famous gas laws and raised the foundation of the atomic theory in chemistry.The publication of these papers gave him at once international reputation they tried to explain why the gases of the atmosphere remain mixed instead of segregating with the heaviest element at the bottom it states that the maximum density of a vapour in contact with its liquid remains the same whether other gases be present or not and the vies that the particles of everykind of elastic fluid are elastic only with regard to their own kind and that the total pressure of the atmosphere equals the sum of the pressures exerted by the individual gases each of which excerts its pressure independently of the others. This was the first step toward his atomic theory of in chemistry. unknown

The paper offered is a free translation of Dalton's paper "On the Absorption of Gases by Water and Other Liquids" published 1805 in "Memoirs of the Literary and Philosophical Society of Manchester"."The paper was read to the Manchester Philosophical Society by Dalton in 1803 and printed in 1805. The appended table in this paper is the first list of atomic weights. Dalton in this publication took the law which William henry had recently enunciated that the amount of of gas absorbed by a liquid is proportional to the pressure and extended it to apply to mixtures of gases using his own law of partial pressures."
