The Architecture of Knowledge: Science, Collecting and Display in Eighteenth-Century Naples

Before the age of the ‘modern’ museum – understood as an institutionalized space for education and entertainment, structured according to standard criteria of classification – the passions of curiosity and wonder materialized in eclectic collections that defied the borders between art, science and nature.1 In cabinets of rarities and in Wunderkammern, mathematical instruments and fossils often ...

The role of divided attention and working memory in mathematical reasoning with the mediation of mathematical knowledge and fluid intelligence in fourth grade elementary students

The purpose of the research is modeling the relationship between divided attention and working memory in mathematical reasoning with the mediation of mathematical knowledge and fluid intelligence in fourth grade elementary students. Statistical population of the research included all fourth grade male students of Primary schools in District 4 of Qom from which 213 students were randomly selecte...

The Origin and Limitations of Modern Mathematical Economics: A Historical Approach

We have first demonstrated that Debreu’s view regarding the publication of The Theory of Games and Economic Behavior by von Neumann and Morgenstern in 1944 as the birth of modern mathematical economics is not convincing. In this paper, we have proposed the hypothesis that the coordinated research programs in the 1930’s, initiated by the Econometric Society and the Cowles Commission for Research...

A novel mathematical model of formulation design of emulsion explosive

A novel mathematical model has been developed to aid the formulation of emulsion explosives. This mathematical model calculated heat of explosion, oxygen balance and raw material cost as a function of explosive ingredients, and the solution of the mathematical model was obtained by a MS Excel program. The effects of the different content of NH4NO3, NaNO3, H2O, and span-80 and composite fuel oil...
