Thomas Saunders Evans’ Greek poem Mathematogonia. The mythological birth of the nymph Mathesis (1839) is one of the outstanding products of the British compositional tradition. The article begins with a brief account of Evans and of the historical context of the poem, which also belongs to the history of mathematics in Britain, and in particular, its teaching in nineteenth-century Cambridge. This is followed by a preliminary note on Mathematogonia; a reproduction of the text of the poem, with Evans’ original preface and notes; an English translation; notes detailing Evans’ sources and borrowings from Tragic texts; and an appendix listing the changes he made after its first publication. The aim is to show what Evans wrote, and to explain what prompted him to do so.

Although better known as a playwright and film-maker, David Mamet started his artistic career as a teacher of acting. In this essay Christophe Collard contextualizes the influences, evaluates the implications, and criticizes some of the implementations of his ‘Practical Aesthetics’ by bridging the divide between Mamet's aesthetic theory and its concretization in practice. Often mistaken for a disingenuous appropriation of the so-called ‘Stanislavsky System’, Mamet's derived ‘Method’ arguably is more functional than original. Nevertheless, Collard argues that his confusion between various interpretations of these precepts is deliberate and serves primarily a reflexive purpose, as illustrated here with an analysis of Mamet's rehearsal play A Life in the Theatre. Christophe Collard works as a research fellow in American theatre and drama at the Vrije Universiteit Brussel (Free University of Brussels), where he recently completed a doctorate about media and genre crossings in the work of David Mamet.

L'objectif de cette étude est de faire dialoguer la simulation numérique et l'expérience pour étudier le comportement en traction d'un multicristal en alliage à mémoire de forme de type CuAlBe. Ce dialogue permet de comparer qualitativement les distributions de transformation martensitique, observée à travers un microscope à grande distance frontale, avec celle obtenue par simulation numérique en utilisant une loi de comportement thermomécanique. Cette loi est basée sur la description de la transformation martensitique à l'échelle du réseau cristallin, elle est implantée dans le code Abaqus®. Les conditions aux limites appliquées lors de la modélisation correspondent aux déplacements mesurés sur les sections frontières par une technique de corrélation d'images. Les propriétés géométriques et cristallographiques des différents grains du multicristal sont quantifiées expérimentalement. L'essai de traction est réalisé à température ambiante où l'alliage a un comportement superélastique. Une bonne corrélation entre les observations expérimentales et les résultats numériques est observée.
