[Set of Nineteenth-Century Scientific and Mathematical Treatises]:

£18,750 · Offered by Shapero Rare Books

An attractive set of nineteenth-century scientific and mathematical treatises, bound to match. I) First edition of Avogadro's magnum opus, containing the first announcement of 'Avogadro's Number'. A major treatise containing Avogadro's famous hypothesis that the number of integral molecules in any gas is always the same for equal volumes, or always proportional to the volumes. This was of great importance for nineteenth-century chemistry in effectively distinguishing between atoms and molecules. Avogadro first published this hypothesis in 1811, but it was largely ignored for another half century, partly because it was published first in Italian (when Italy was at the periphery of scientific research) and subsequently only in minor French, German and English scientific journals. II) First edition of this rare publication, considered an important scientific journal above all for being the means of dissemination of the mathematical theories of A.L. Cauchy in Italy. The second volume contains some of Cauchy's fundamental works translated into Italian, including Sulla meccanica celeste. III) First publication of Cauchy's equation, which determined the relationship between the wavelength of light and the refractive index of a material the light passes through. Cauchy produced this publication, which consisted of his own papers, in 1835 and 1836. This memoir was issued as eight parts of his periodical Nouveaux Exercices de Mathématiques, and was a successor to his earlier Exercices
