‎---- TROIS OUVRAGES RELIES EN UN VOLUME SUR LA CONTREVERSE RELATIVE AUX FORCES VIVES ---- "Collection of THREE WORKS RELATING TO THE VIS-VIVA CONTROVERSY. THE FIRST is MAIRAN'S reply to Madame DU CHATELET's Institutions de physique in which she had attacked his 1728 memoir condemning the vis-viva principle. The conflict between MAIRAN and DU CHATELET was a proonged and acrimonious one, in which curiously, VOLTAIRE was to take the side of MAIRAN. The Marquise had originally been a supporter of MAIRAN and of the Newtonian-Cartesian viewpoint, but was broutht over to the Leibnizian camp. MAIRAN's view of the problem was the force of a body depends on its velocity rather than the squae of its velocity. Contrary to some, MAIRAN was aware that velocity should be treated as a vector quantity, bt his arguments in general did not provide anay special clarification to the problem". (DSB IX pp. 33-34 & Bibliotheca Mechanica p. 211/212 -- The SECOND WORK by MAIRAN is the reediton of his 1728 memoir to the Academy by Abbé DEIDIER -- The THIRD WORK by Abbé DEIDIER is a refutation of the vis-viva theory**7752/ARM2A-8771/ARB6‎
