Contest and community : wonder-working in Christian popular literature from the second to the fifth centuries CE

Schwartzman, Lauren J. January 2013 (has links)
In this thesis, I hope to demonstrate that what I call the magic contest tradition, that is the episodes of competitive wonder-working that appear in a wide variety of apocryphal and non-canonical Christian texts, made an important contribution to the development of Christian thought during the second to the fifth centuries CE. This contribution was to articulate ‘the way’ to be a Christian in a world which was not isolated from the secular, and not insulated from the reality of the Roman empire. First, I demonstrate that a tradition of texts which feature magic contests exists within the broader scope of non-canonical Christian literature (looking at this literature across communities, regions and time periods). Second, I identify what the major features of the traditions are, e.g. what form the narratives take, what the form for a magic contest is, and what the principles used to build the magic contests are, and how these principles feature in the texts. The principles I identify are power, authority, ritual, and conversion, as well as their use as historical exempla. Third, I discuss what the texts did in the context of the time period, and for the communities that produced and read them: in other words, how did the this tradition work? I show that they served multiple purposes: as tests of faith, religious truth and ways to proclaim such; as constructors and markers of group identity (and the perilous task of identifying the insiders and those who should be outsiders); as calls to unity within the overarching diversity of the times and places, and a unified front for the ‘battle’ against evil. I suggest that the texts present a model for how one could decide what the ‘true faith’ was and how one could practice it in the turbulent environment that early Christians faced both before and after Constantine.

Towards quantum telecommunication and a Thorium nuclear clock

Radnaev, Alexander G. 17 August 2012 (has links)
This thesis presents the investigations of Rubidium atoms in magneto-optical traps and triply charged Thorium ions in electrodynamic traps for future advances in long-distance quantum telecommunication, next generation clocks, and fundamental tests of current physical theories. Experimental realizations of two core building blocks of a quantum repeater are described: a multiplexed quantum memory and a telecom interface for long-lived quantum memories. A color change of single-photon level light fields by several hundred nanometers in an optically thick cold gas is demonstrated, while preserving quantum entanglement with a remotely stored matter excitation. These are essential elements for long-distance quantum telecommunication, fundamental tests of quantum mechanics, and applications in secure communication and computation. The first trapping and laser cooling of Thorium-229 ions are described. Thorium-229 nuclear electric quadrupole moment is revealed by hyperfine spectroscopy of triply charged Thorium-229 ions. A system to search for the isomer nuclear transition in Thorium-229 is developed and tested with the excitation of a forbidden electronic transition at 717 nm. Direct excitation of the nuclear transition with laser light would allow for an extremely accurate clock and a sensitive test bed for variations of fundamental physical constants, including the fine structure constant.
