    Journal of Biblical and Theological Studies JBTSVOLUME 2 | ISSUE 2 Christianity and the Philosophy of Science Divine Action and the World of Science: What Cosmology and Quantum Physics Teach Us about the Role of Providence in Nature 247 Bruce L. Gordon [JBTS 2.2 (2017): 247-298] Divine Action and the World of Science: What Cosmology and Quantum Physics Teach Us about the Role of Providence in Nature1 BRUCE L. GORDON Bruce L. Gordon is Associate Professor of the History and Philosophy of Science at Houston Baptist University and a Senior Fellow of Discovery Institute’s Center for Science and Culture Abstract: Modern science has revealed a world far more exotic and wonder- provoking than our wildest imaginings could have anticipated. It is the purpose of this essay to introduce the reader to the empirical discoveries and scientific concepts that limn our understanding of how reality is structured and interconnected—from the incomprehensibly large to the inconceivably small—and to draw out the metaphysical implications of this picture. What is unveiled is a universe in which Mind plays an indispensable role: from the uncanny life-giving precision inscribed in its initial conditions, mathematical regularities, and natural constants in the distant past, to its material insubstantiality and absolute dependence on transcendent causation for causal closure and phenomenological coherence in the present, the reality we inhabit is one in which divine action is before all things, in all things, and constitutes the very basis on which all things hold together (Colossians 1:17). §1. Introduction: The Intelligible Cosmos For science to be possible there has to be order present in nature and it has to be discoverable by the human mind.

  • Comments by Jon Mark Meeting of Board of Trustees December 13, 2016
    Comments by Jon Mark Meeting of Board of Trustees December 13, 2016 Dr. John Salimbene: It is with great sadness that we note the tragic death of Dr. John Salimbene. As has been publicly reported, Dr. Salimbene died in the fire that occurred in his home on Sunday, December 4, 2016. Many of his neighbors and other Scarsdale residents were his patients and he was fondly remembered by one of them as an old-fashioned town doctor. In addition, for more than half a century, Dr. Salimbene served as Tuckahoe’s village-appointed physician. Earlier this year, the Tuckahoe Police Department honored the doctor for his many years of kind and compassionate service. Here in Scarsdale, this Board and Village staff send our sincere condolences and prayers to the Salimbene family at this difficult time. We ask for a moment of silence in Dr. Salimbene’s memory. Dr. Richard Garwin : On November 22, 2016, President Barack Obama presented Dr. Richard Garwin with the Presidential Medal of Freedom. Dr. Garwin is a long-time resident of the Village. In making that award, the President noted that Dr. Garwin is a polymath physicist who earned a Ph.D. under Enrico Fermi at age 21 and subsequently made pioneering contributions to U.S. defense and intelligence technologies, low-temperature and nuclear physics, detection of gravitational radiation, magnetic resonance imaging (MRI), computer systems, laser printing, and nuclear arms control and nonproliferation. He directed Applied Research at IBM’s Thomas J. Watson Research Center and taught at the University of Chicago, Columbia University, and Harvard University.

  • Research/Teaching Statement Gerard Awanou 1 Trivariate Splines
    Research/Teaching statement Gerard Awanou I would like to describe in this statement the research I have done and comment on future directions. My work has been on trivariate splines for scattered data in- terpolation and numerical solution of partial differential equations, particularly, the Navier-Stokes equations. Another line of my research is mathematical finance. I have been interested in risk minimization in regime switching and two factor stochastic volatility models. I will describe my recent success in the construction of a family of mixed elements for three dimensional elasticity, a problem which was open for over 40 years. 1 Trivariate splines Let us assume that Ω is a three dimensional domain with a triangulation 4, i.e. the union of nonoverlapping tetrahedra with the property that the intersection of any two tetrahedra is either empty, a common vertex, a common edge or a common face. A spline function of degree d and smoothness r over Ω is a r times differentiable func- tion which is a polynomial of degree d when restricted to each tetrahedron. Finite elements are examples of spline functions. Scattered data interpolation A typical problem in surface design is the following: Given a set of scattered points in IR3, which are assumed to be at the vertices of a triangulation 4, find a spline with appropriate smoothness which interpolates the given data at the vertices. The resolution of this problem is by means of the construction of locally supported spline functions with high smoothness. I have implemented C1 spline functions in [6] on a special triangulation.
