    Eternal God: Divine Atemporality in Thomas Aquinas

    Get PDF
    The recent trend among many philosophers of religion has been to interpret divine eternity as an everlasting temporality in which an omnitemporal God exists in and throughout the whole of time. This is in contrast to the classical account of divine eternity as atemporal, immutable existence. In this paper, Aquinas' use of Boethius's definition of eternity as “the whole, perfect, and simultaneous possession of endless life” is analyzed and explained in contradistinction to Aristotle's definition of time. This analysis is then used to respond to Nicholas Wolterstroff's argument in "God Everlasting" that God's knowledge of temporal events infects God with temporality and mutability. The argument concludes by introducing an important distinction between absolute simultaneity and temporal simultaneity, which allows us to hold God is omniscient because he is absolutely simultaneous with all events but is not temporally simultaneous with any event

    Frozen reaction fronts in steady flows: a burning-invariant-manifold perspective

    Full text link
    The dynamics of fronts, such as chemical reaction fronts, propagating in two-dimensional fluid flows can be remarkably rich and varied. For time-invariant flows, the front dynamics may simplify, settling in to a steady state in which the reacted domain is static, and the front appears "frozen". Our central result is that these frozen fronts in the two-dimensional fluid are composed of segments of burning invariant manifolds---invariant manifolds of front-element dynamics in xyθxy\theta-space, where θ\theta is the front orientation. Burning invariant manifolds (BIMs) have been identified previously as important local barriers to front propagation in fluid flows. The relevance of BIMs for frozen fronts rests in their ability, under appropriate conditions, to form global barriers, separating reacted domains from nonreacted domains for all time. The second main result of this paper is an understanding of bifurcations that lead from a nonfrozen state to a frozen state, as well as bifurcations that change the topological structure of the frozen front. Though the primary results of this study apply to general fluid flows, our analysis focuses on a chain of vortices in a channel flow with an imposed wind. For this system, we present both experimental and numerical studies that support the theoretical analysis developed here.Comment: 21 pages, 30 figure

    Reinventing the 21st Century Professor

    Standardized testing, MOOCs, automated systems, complex pedagogies, and adoption of all manner of trendy technologies into every classroom situation are currently presented as the solutions to current educational challenges. Nonsense. 21st century students certainly interact and engage in entirely new ways, but great teacher/student communication is still at the core of building great learning environments, be they live lectures or entirely digital online courses. There are tons of great new tools out there to facilitate great communication but they should not all be automatically ignored by older generations, nor immediately embraced as a solution in and of themselves. Professor Boyer will share his two decades of experience with new technologies and evolving student mindset in creating both record-breaking super-large live courses, as well as the transition to fully digital courses that actually increase student engagement and flexibility, while serving 3500-4000 students each academic year. The time has come to totally disrupt the standard operating procedure of the classic college classroom by encouraging educators to find their voice (amplified by selective use of technologies suited to them and their subject matter), to focus on bringing passion and inspiration back to the forefront of their profession. When it comes to teachers and technologies: EMBRACE not REPLACE! The best teachers will EMBRACE the technologies that help them better communicate with students, but those technologies will never REPLACE human to human interaction. But blending the best communicators with the best technology has to offer will produce some amazing and unpredictable opportunities

    Compilation of a materials cost database for a web-based composites cost estimator

    Get PDF
    Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2001.Includes bibliographical references (p. 44-45).The production of composite materials continues to be an expensive process. The WEB-Based Cost Estimation Model enables one to approximate the cost of manufacturing composites, so as to assist the user in making sound economic decisions. An extensive, up-to-date materials database is an essential part of such a cost estimator. This paper presents a list of materials to be added to the existing database and also derives a materials selection chart for six manufacturing processes.by John R. Boyer.S.B
