SUMMARY:Knowing by drawing: geometric material models in 19th Century Fran
 ce
DESCRIPTION:Art and Math Seminar Presents:\n\nSpeaker: Frédéric Brechenmac
 her\n\nAbstract: This paper investigates several historical collections o
 f geometric material models\, drawings\, photographs and other types of g
 raphical representations. The practice of model drawing played a key role
  in the development of descriptive geometry and\, more generally\, of mat
 hematics from the mid 18th century to the beginning of the 20th century. 
 For a long time\, material models were competitors of professors and mode
 l drawing an alternative to lectures. Historical sources such as drawings
  (and later photographs and films)\, models (of all kinds\, including rel
 ief drawings) and instruments\, highlight the key role played by specific
  forms of non-textual knowledge in mathematics. These collections raise m
 any questions concerning the role played by instruments in mathematics an
 d its relation to other sciences\, techniques and industry\, but also to 
 the fine arts. To be sure several instruments originated from the practic
 e of geometric model drawing. More importantly\, models and drawings them
 selves came to be considered as specific types of instruments by the end 
 of the 19th century : graphical instruments.\n\nhttp://next-to-u.app/even
