DESCRIPTION:[b]DIAS Lecture by Giovanna Cifolletti\, Membres émérites et h
 onoraires\, Directrice d'études de l'EHESS [/b] [nl] [nl] [b] From Early 
 modern (European) symbolic algebra: a rhetorical project ? [/b] [nl] [nl]
  \n\nMy research project aims to understand the sense of the symbolic alg
 ebra of Viète and Descartes\, in the context of 16th-century Europe. To a
 pply a sociological scheme could hardly bridge the gap between mathematic
 al theory and practice on the one hand and the actual concerns of scienti
 sts and practitioners (including masters of crafts and merchants) on the 
 other. Hence I opted for a social history approach in the sense defined b
 y Lucien Febvre in connection with 16th-century people: our purpose is to
  see how people formulated their problems and  found strategies to solve 
 them. [nl] [nl] \nThis invites us to search for information in documents 
 about the history of books and printing\, of universities\, of academies 
 and civic schools. At the theoretical level\, we look for the connections
  of algebra\, geometry and arithmetic with other disciplines or liberal a
 rts: besides mathematics\, these include grammar\, rhetoric and logic or 
 dialectic\; within mathematics\, there are the links with the mathematica
 l arts music and astronomy as well as with many subordinate arts such as 
 optics or chronology\, calendars and commercial arithmetic. Febvre’s appr
 oach insists on paying attention to the perspective of the actors\, not o
 nly as an intellectual curiosity but as the search for an actual comparis
 on with our research. In fact\, Lucien Febvre shares categories with the 
 people he studies: for instance putting problems and solutions at the cen
 ter of intellectual life is a typical move of 16th-century rhetoric and l
 ogic. [nl] [nl] \nWith the study of symbolic algebra we are in a similar 
 position: algebra in the 16th- century was transformed to become the scie
 nce of formulating problems and their solutions. Today we shall see in pa
 rticular how 15th- century vernacular rhetoric and logic of Lorenzo Valla
  created the conditions for this transformation in the works of Jacques P
 eletier\, so that on this basis algebra itself replaced logic in Descarte
 s and Fermat.\n\n[nl] [nl][b]About[/b] [nl]\nGiovanna Cifoletti\, Profess
 or and Directrice d'Etudes à l'EHESS\, L’école des hautes études en scien
 ces sociales\, the School for Advanced Studies in the Social Sciences\, H
 istoire des sciences et des techniques\, Doctor of Philosophy.\nHer resea
 rch areas are the History of Mathematics\, especially early modern algebr
 a. Intellectual and social European and Mediterranean history in the earl
 y modern period. Abacus Schools: texts and commercial practices. Mathemat
 ics\, rhetoric and logic in early modern Europe\, especially among jurist
 s and mathematicians.\n[nl] [nl] The lecture takes place in the DIAS Audi
 torium\, Fioniavej 34from 11:15 to 12:15. Everybody is welcome and no reg
 istration is needed. [nl][nl]
