First edition of the French translation made by Chladni himself, bearing the inscription \u00ab A son Excellence Mr. le Comte de Lac\u00e9p\u00e8de. Hommage de l\u2019Auteur \u00bb..<\/span><\/p>\n Chladni and Count \u00c9tienne de Lac\u00e9p\u00e8de (1756\u20131825) met at the Tuileries in the year this treatise was published. The event was organised in February by Napoleon; the Emperor wished for Chladni to give a demonstration of his famous \u2018acoustic figures\u2019 in Paris.<\/p>\n Lac\u00e9p\u00e8de is said to have helped convince Chladni to produce this translation:<\/p>\n \u00ab Chladni ne tarda pas \u00e0 se lier d\u2019amiti\u00e9 avec plusieurs d\u2019entre eux [savants fran\u00e7ais]. Ce furent surtout MM. De la Place, Berthollet, Lacep\u00e8de et Biot qui, prenant un vif int\u00e9r\u00eat \u00e0 la science dont il leur avait r\u00e9v\u00e9l\u00e9 les myst\u00e8res, le press\u00e8rent de publier une traduction fran\u00e7aise de son ouvrage sur l\u2019acoustique \u00bb. (Revue et Gazette musicale, n\u00b041, 5e<\/sup> ann\u00e9e, 14 octobre 1838, p.402.)<\/i><\/p>\n Lac\u00e9p\u00e8de wrote a Po\u00e9tique sur la musique<\/i>, published in 1783; this explains the interest shown by this naturalist \u2013 the successor to Buffon \u2013 in the work of his counterpart.<\/p>\n Chladni (1756\u20131827) is regarded as the father of modern acoustics. He was the first to set out the general relationship between the frequency of vibration and pitch in tabular form, thereby laying the foundations for modern acoustics. The experiments he carried out by placing sand on metal or glass plates, which he then set vibrating with a bow, yielded astonishing results. Indeed, the sand settled into different geometric patterns depending on the vibrations of the plates. These patterns are still known today by the name of their famous inventor: \u2018Chladni figures\u2019. (PMM)<\/p>\n “Except for a few publications on meteorites, Chladni devoted his research to the study of acoustics and vibration. He first described his early experiments using the sand figures in Endeckunger \u00fcber die Theorie des Klanges<\/i>. They were presented with additional observations in Die Akustik<\/i>, which is also a general acoustics text containing very complete historical material. This appeared in French translation in 1809 (Trait\u00e9 d’acoustique<\/i>) in which he gives an autobiographical summary in the introduction” (DSB III p. 258).<\/p>\n Furthermore, the volume concludes with two reports signed by Gaspard de Prony but also co-signed by Lac\u00e9p\u00e8de, devoted respectively to the clavi-cylindre<\/i> and to Chladni\u2019s own work.<\/p>\n The plates illustrate a variety of geometric shapes obtained during the experiments.<\/p>\n Other provenance : Jesuit college (library label on inner-cover, as well as rubber stamp and number on title).<\/p>\n Small occasional marginal waterstain in a few leaves, otherwise a very fine copy of important scientific provenance.<\/p>\n","protected":false},"excerpt":{"rendered":" 8vo (192 x 120 mm) 2 nn.ll., XXVIII, 375 pp, 8 engraved folding plates.
