Pacioli and humanism: pitching the text in Summa Arithmetica
Despite the wide cross-disciplinary influence of Fra’ Luca Pacioli’s Summa de Arithmetica, Geometria, Proportioni et Proportionalita (Summa), it has been criticized as being both difficult to read and written in a mixture of bad Italian and bad Latin; but, paradoxically, intellectuals
of Pacioli’s day praised the style of writing in Summa. Can both viewpoints be correct? The answer to this question is sought by identifying what may have inspired Pacioli to write Summa in the manner he did. In doing so, the article considers the times in which he lived and, in particular,
the impact that Renaissance Humanism and Humanist Education
may have had upon his writing style. The article finds both views were correct in their own timeframes and contexts and that Pacioli’s writing style was both an appropriate one with which to address a contemporary merchant society and one which would impress and gain the approval of his fellow humanist educators and patrons
The market for Luca Pacioli's Summa arithmetica
This paper looks at an aspect of Luca Pacioli and his Summa
Arithmetica that has not previously been explored in detail – the market for which he wrote the book. In order to do so, it follows a path identified by two clues in the bookkeeping treatise as to the nature of this market that modern eyes, unaware of how life was in late 15th century Italy, have missed. After discussing the curriculum taught in schools at that time, this paper considers a range of possible markets for which the book may have been written. The paper concludes that it was written primarily for, and sold mainly to, merchants who used the book as a reference text, as a source of pleasure from the mathematical puzzles it contained and as an aid for the education of their sons

Itinerant ferromagnetism in a two-dimensional atomic gas
Motivated by the first experimental evidence of ferromagnetic behavior in a
three-dimensional ultracold atomic gas, we explore the possibility of itinerant
ferromagnetism in a trapped two-dimensional atomic gas. Firstly, we develop a
formalism that demonstrates how quantum fluctuations drive the ferromagnetic
reconstruction first order, and consider the consequences of an imposed
population imbalance. Secondly, we adapt this formalism to elucidate the key
experimental signatures of ferromagnetism in a realistic trapped geometry.Comment: Accepted for publication in Phys. Rev.
