Furthermore, Modem practitioners of mathematics have been taught their mathematics by teachers who have been taught by teachers (who . etc.) who have been taught by mathematicians. In both senses, practitioners' mathematics can then be regarded as »applied mathematics«. - Wikipedia: Jens Egede Høyrup, born 1943 in Copenhagen, is a Danish historian of mathematics, specializing in pre-modern and early modern mathematics, ancient Mesopotamian mathematics in particular. He is especially known for his interpretation of what has often been referred to as Old Babylonian "algebra" as consisting of concrete, geometric manipulations.

A good and very clean copy. -Dal testo: Le pagine che seguono esplorano le tracce di un modo di pensare le aree e le lunghezze che a noi pare strano ma che in varié culture matema-tiche é stato cosí consueto che era superfino spiegarlo; cosí strano e cosí consueto, infatti, che gli storici moderni hanno dichiarato sbagliati, confusi o privi di senso i passi nelle fonti che riflettono questa struttura concettuale. Si tratta dell'abitudine di immaginarsi le linee come portatrici di una larghezza virtuale di una unitá, e le aree come composte di strisce unitarie di questa sorta: abitudine diffusa in molti ambienti di agrimensura pratica (dove é facile, grazie all'uniformitá delle usanze, essere d'accordo su una sola larghezza standardizzata: quella dell'unitá primaria di lunghezza; dove, per cosí dire, la térra si misura come si vendono ancora oggi le stoffe con la loro larghezza físicamente fissata) - abitudine pero che si riflette anche in testi con provenienza piü teórica benché ancora ispirati o tinti dalla misura pratica e dal suo linguaggio. - Wikipdia: Jens Egede Høyrup, born 1943 in Copenhagen, is a Danish historian of mathematics, specializing in pre-modern and early modern mathematics, ancient Mesopotamian mathematics in particular.

Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - This book provides a unique perspective on the history of European algebra up to the advent of Viète and Descartes. The standard version of this history is written on the basis of a narrow and misleading source basis: the Latin translations of al-Khwarizmi, Fibonacci's Liber abbaci, Luca Pacioli's Summa, Cardano's Ars magna-with neither Fibonacci nor Pacioli being read in detail. The existence of the Italian abacus and German cossic algebra is at most taken note of but they are not read, leading to the idea that Viète's and Descartes' use of genuine symbolism (not only abbreviations), many unknowns, and abstract coefficients seem to be miraculous leaps. This book traces the meandering development of all these techniques along with the mostly ignored but very important parenthesis function, by means of detailed readings of all pertinent sources, including the abacus and cossic algebra and French algebra from Chuquet to Gosselin. It argues for a necessary distinction between abbreviating glyphs and genuine symbols serving within a symbolic syntax, which allows it to trace the emergence of symbolic calculation. Characterization of the mathematical practice of the environment within which Viète and Descartes moved allows for an explanation of how these two figures did not even need to invent abstract coefficients but rather received them as a gift.
