Linear Collider Physics

Studies of the physics potential of the Future Linear Collider are establishing a broad programme which will start in the region of 350 to 500 GeV C. of M. energy. The main goal is to understand why the standard model works; by studying the properties of the Higgs sector, if it is within reach, and by exploring the complex world of Supersymmetry, if it is real. If the Higgs boson is not found soon, then the Linear Collider can test the standard model with high precision measurements, both at energies approaching 1 TeV and with high statistics at the Z0.Comment: 12 pages, 4 figures, to be published in Proceedings of La Thuile 200

Ignorance and Blame

Sometimes ignorance is a legitimate excuse for morally wrong behavior, and sometimes it isn’t. If someone has secretly replaced my sugar with arsenic, then I’m blameless for putting arsenic in your tea. But if I put arsenic in your tea because I keep arsenic and sugar jars on the same shelf and don’t label them, then I’m plausibly blameworthy for poisoning you. Why is my ignorance in the first case a legitimate excuse, but my ignorance in the second case isn’t? This essay explores the relationship between ignorance and blameworthiness

Alternative Experimental Protocol for a PBR-Like Result

Pusey, Barrett and Rudolph (PBR) have recently proven an important new theorem in the foundations of quantum mechanics. Here we propose alternative experimental protocols which lead to the PBR result for a special case and a weaker PBR-like result generally. Alternative experimental protocols support the assumption of measurement independence required for the PBR theorem.Comment: 4 pages, 1 figur

Horse and Herald: Posidippus' Equestrian Angelia

Posidippus’ epigrams for equestrian victors (the Hippika, AB 71–88) build on epinician convention by maintaining the central role of the herald’s proclamation— the angelia—in the representation of athletic achievement. In a few of these epigrams, however, Posidippus embeds the horse itself in postvictory rituals. For example, the horse brings the crown to the victor, replacing the figure of the herald who announced and crowned victors; or, in a narrative of the race’s aftermath, the horse, incredibly, chooses the victor. Posidippus’ horses, therefore, act as causal agents for the glory of their owners, and his detailed descriptions transform the horse from flesh-and-blood equine to everlasting (literary) monument. Les épigrammes de Posidippe sur les victoires équestres (les Hippiques, 71-88 A.-B.) s’appuient sur une convention poétique propre aux épinicies qui maintient le rôle de la proclamation du héraut – l’angelia – dans la représentation de la réussite athlétique. Cependant, dans quelques-unes de ces épigrammes, Posidippe intègre le cheval lui-même au rituel marquant la victoire. Par exemple, le cheval apporte la couronne au vainqueur en remplacement de la figure du héraut qui annonce et couronne les vainqueurs ; ou encore, dans le récit de l’après-course, le cheval choisit, de façon surprenante, le vainqueur. Les chevaux de Posidippe interviennent donc en tant qu’agents causaux dans la gloire de leur propriétaire. Ses descriptions détaillées transforment ainsi l’être de chair et de sang qu’est le cheval en un monument (littéraire) éternel.https://www.utpjournals.press/doi/full/10.3138/mous.16.3.00

Recollections of My Research in Developing the Heart-Lung Machine at Jefferson Medical College

A personal memoir written by Dr. Bernard J. Miller about his introduction to and interest in medical research as well as his experiences working on the heart-lung machine. He focuses specifically on his working relationship with John H. Gibbon, Jr., the development of a viable oxygenator and ventilator, and early testing of the machine on animal
