An augmented reality (AR) application that complements a DNA precipitation experiment has been developed for use on mobile devices. The AR experience provides atomistic detail on the reasoning behind the experimental observations. The development of the application is described, as are the download data. In a pilot survey, the students were asked about their use or intended use of the application. More students used the application after the laboratory compared with before or during the laboratory. These results suggest that students prefer to use this type of technology as a reflective tool to consolidate their laboratory experience.

The climactic duel of Shakespeare's Hamlet culminates a growing pattern of sympathy between Hamlet's madness and the madness of the Francophilic duel with rapiers. On one level, the play operates as a sustained criticism of the duel of honour as it existed in England at the turn of the seventeenth century, and also of the desire for revenge and recompense that drove it. Hamlet's mental decline is correlated to an increasing sympathy with the rapier, and it is only by breaking this sympathy and returning to chivalric martial English values that Hamlet is able to achieve redemption. Le duel fnal dans la tragédie de Shakespeare, Hamlet, est le point culminant d'une trajectoire qui lie de plus en plus étroitement la folie de Hamlet et un engouement francophile pour les duels à la rapière. à un niveau, la pièce fonctionne comme une critique du duel d'honneur tel qu'il se pratiquait en Angleterre au tournant du XVIIe siècle, et du désir de vengeance et de récompense qui l'animait. Le déclin psychologique de Hamlet s'accompagne d'une attirance croissante pour la rapière, et ce n'est qu'en brisant cette attirance et en renouant avec des valeurs martiales anglaises héritées de la chevalerie que Hamlet peut atteindre la rédemption.
