New theories for new instruments: Fabrizio Mordente's proportional compass and the genesis of Giordano Bruno's atomist geometry.

摘要: The aim of this article is to shed light on an understudied aspect Giordano Bruno's intellectual biography, namely, his career as a mathematical practitioner. Early interpreters, especially, have criticized mathematics for being "outdated" or too "concrete". However, thanks developments in the study early modern and rediscovery first writings (four dialogues Fabrizio's Mordente proportional compass), we are position better understand mathematics. In particular, aims reopen question whether Bruno anticipated concept infinitesimal quantity. It does so by providing analysis Mordente's compass historical circumstances under which those were written.
