Quantum Imaging beyond the Diffraction Limit by Optical Centroid Measurements

I propose a quantum imaging method that can beat the Rayleigh-Abbe diffraction limit and achieve de Broglie resolution without requiring a multiphoton absorber as the detector. Using the same non-classical states of light as those for quantum lithography, the proposed method requires only intensity measurements, followed by image post-processing, to produce the same complex image patterns as those in quantum lithography. The method is expected to be experimentally realizable using current technology.Comment: 4 pages, 2 figures; v2: accepted by PRL, see also the accompanying Viewpoint commentary by Anisimov and Dowling [Physics 2, 52 (2009), http://physics.aps.org/articles/v2/52

Apocalyptic Beauty

A potent and formative text for a theological aesthetics faithful to the God revealed in the Scriptures is the Apocalypse of John (Revelation). An apocalyptic viewpoint is beautiful inasmuch as it observes the whole from within the part of time/space and inasmuch as the apocalyptic vision provides considerable unity of diverse theological themes with various expansions and enhancements, hence mimicking the very function of theological beauty to communicate the whole (God) in the part (here, in space-time). This essay traces major themes throughout Scripture, utilizing inter-textual interpretation en route, and seeks to clarify the Book of Revelation\u27s role in recapitulation, consummation, and consolation (i.e. beauty). Commenting on how the Apocalypse meets the criteria for being theologically beautiful, this essay then seeks to show how this role of beauty--and in particular, consolation--attracted the early Christian devotees visiting/dwelling-in the catacombs (A.D. 150-500) to make the Apocalypse of John one of the major contributors to their artwork

Different Clusters of Text from Ancient China, Different Mathematical Ontologies

Sources attesting to mathematical activities in ancient China form at least four distinct clusters of texts, bespeaking at least four different—though overlapping—ways of practicing mathematics. I will focus on two such sets of documents: the canons that in the seventh century constituted one of the two curricula taught in the Imperial “School of Mathematics,” and manuscripts recently excavated from tombs sealed in the last centuries BCE. I will argue that these two sets of documents testify to two different ways of practicing mathematics, which related to different material practices. Accordingly, we can perceive that mathematical objects were shaped and explored in different ways, with significant consequences for the knowledge produced

Integrative biological simulation praxis: Considerations from physics, philosophy, and data/model curation practices

Integrative biological simulations have a varied and controversial history in the biological sciences. From computational models of organelles, cells, and simple organisms, to physiological models of tissues, organ systems, and ecosystems, a diverse array of biological systems have been the target of large-scale computational modeling efforts. Nonetheless, these research agendas have yet to prove decisively their value among the broader community of theoretical and experimental biologists. In this commentary, we examine a range of philosophical and practical issues relevant to understanding the potential of integrative simulations. We discuss the role of theory and modeling in different areas of physics and suggest that certain sub-disciplines of physics provide useful cultural analogies for imagining the future role of simulations in biological research. We examine philosophical issues related to modeling which consistently arise in discussions about integrative simulations and suggest a pragmatic viewpoint that balances a belief in philosophy with the recognition of the relative infancy of our state of philosophical understanding. Finally, we discuss community workflow and publication practices to allow research to be readily discoverable and amenable to incorporation into simulations. We argue that there are aligned incentives in widespread adoption of practices which will both advance the needs of integrative simulation efforts as well as other contemporary trends in the biological sciences, ranging from open science and data sharing to improving reproducibility.Comment: 10 page

Paper Friends: Honoring God in What You Read

Choosing literature to read and developing a relationship with it is similar to meeting people and choosing who will be our friends. Valerie Pors has created a clever parallel between evaluating literature and building friendships

Wim Wenders’ Use of Space in The Million Dollar Hotel

Wim Wenders has been quoted as saying, of his own development as a filmmaker, that he is “a painter of space engaged on a quest for time” (qtd. in Graf, 2002, p.63). This paper offers a systematic assessment of the way Wenders creates the filmic space of The Million Dollar Hotel (Wenders, 1999) from a place existing in downtown Los Angeles: the Frontier Hotel on East 5th St., LA (with its companion hotel, the Rosslyn, just across the street). This study considers both place and space as filmic effects, which operate on a continuum from documentary to fantasy
