Viewing scenes of the history of chemistry through the opera glass

Artistic creation has always reflected the spirit of the moment and opera has not been an exception. There are several examples of operas which appeared at key moments of the development of science, portraying them. Additionally there are also operas that emerged after scientific events or the lifetime of the scientists they were inspired on. In what concerns chemistry, the first category could be exemplified by the apothecary operas (already discussed by the author in a previous paper of this journal) while the others could be illustrated by recent operas such as Dr. Atomic or Madame Curie. Continuing our endeavor of establishing relations between opera and chemistry, and considering that history of science plays an important role in the process of teaching and learning sciences, some milestones of the history of chemistry are here revisited through the opera glass. The operas analyzed have been grouped in the following categories: Operas of Fire and Metallurgy, Operas of the Philosophers of Antiquity, Operas of Alchemy, Operas of the Age of Enlightenment, Operas of the Revolutions and Operas of Entropy.Thanks are due to the Foundation for Science and Technology (FCT–Portugal) and FEDER (European Fund for Regional Development)-COMPETE/QREN/EU for financial support through the research unity PEst-C/QUI/UI686/2013.

The Science of Pronominal Usage: He and It in Co-Reference to Inanimate Objects in Late Middle English Texts on Alchemy

This is the author's accepted manuscript. The published version can be found at http://dx.doi.org/10.1177/0075424210384225This article explores the variation between he and it in coreference to inanimate entities (such as mercury, sulfur, and salt). Using alchemical texts from the fifteenth century as material, the article demonstrates that there was much more variation in pronominal reference in this period than has previously been shown. Of the possible explanations suggested by previous research, the earlier grammatical gender system and transference from Latin do not seem to play a role, while pronoun clustering and pronominal reanalysis appear to influence the quantitative distribution. The scale of individuation used by Siemund and Stenroos to explain similar usage is shown not to be a straightforward predictor. Other factors such as personification and perceived similarities between animate and inanimate entities may affect the degree of perceived individuation. The choice of he over she seems to be influenced by pronominal reanalysis and straightforward personification in some cases. In other instances, it is speculated that the he usage reflects (stereotypical) gender conceptions in the Middle Ages
