61. Computations In Riemann Geometry - Introduction are there any general conclusions we can draw about product metrics? of that quintessential practical application of geometry, general Relativity, http://www.rwc.uc.edu/koehler/crg/intro.html

Introduction This is a book for students of General Relativity, by a student of General Relativity. Most of us understand the subject to the extent that we do, due to the detailed computations we have carried out and whose significance we have tried to understand. Our intent here is to provide examples of the computational techniques, and a compendium of sometimes useful and occasionally interesting results, which might enable us as students to develop some intuition about the applications of Riemannian Geometry to the study of GR. There are several over-arching questions which have guided our investigations and which give some shape to this work: Is there an invariant way to capture the essential characteristics of the space(time) described by a given metric? Given two metrics, are there any clues to indicate that they are or are not in the same diffeomorphism class? What effect does dimension have on geometry in a class of related metrics? Are there any general conclusions we can draw about product metrics? Most students will find these questions interesting in their own right, yet they are almost completely ignored in most texts. The typical student of GR usually has little time to completely analyze the Schwarzschild Solution to Einstein's Equations before embarking on an individual course of research. This leaves no opportunity for a leisurely and moderately thorough examination of a variety of metrics which might lead to greater understanding.

The Search for Philosophical Novelty Extraordinary public clamor greeted an announcement of the joint meeting of the Royal Society of London and the Royal Astronomical Society on the 6th of November, 1919. To within acceptable margin of error, astronomical observations during the solar eclipse the previous May 29 th revealed the displacement of starlight passing near the surface of the sun predicted by Einstein's gravitational theory of curved spacetime. By dint of having "overthrown" such a permanent fixture of the cognitive landscape as Newtonian gravitational theory, the general theory of relativity at once became a principal focus of philosophical interest and inquiry. Although some physicists and philosophers initially opposed it, mostly on non-physical grounds, surveyed here are the principal philosophical interpretations of the theory accepting it as a definite advance in physical knowledge. Even so, these include positions ill-informed as to the mathematics and physics of the theory. Further lack of clarity stemmed from the scientific

GP GPU General-Purpose Computation Using Graphics Hardware Forums Introduction GPGPU stands for General-Purpose computation on GPUs . With the increasing programmability of commodity graphics processing units (GPUs), these chips are capable of performing more than the specific graphics computations for which they were designed. They are now capable coprocessors, and their high speed makes them useful for a variety of applications. The goal of this page is to catalog the current and historical use of GPUs for general-purpose computation. Contribute Have some GPGPU News to Contribute? Submit it!

An Implementation of a FIR Filter on a GPU Alexey Smirnov and Tzi-cker Chiueh from Stony Brook University have published a technical report describing an implementation of a FIR filter on a GPU. The results of the performance evaluation using a Geforce 6600 video card and a Pentium 4-HT 3.2 GHz-based PC indicate that the GPU implementation is better than the SSE-optimized CPU implementation for certain input parameters.

67. Non-Euclidean Geometry With LOGO This document is a Review of NonEuclidean geometry with LOGO by Helen of the project is on geometry and graphics rather than on general programming. http://www.bham.ac.uk/ctimath/reviews/logo.html

Non-Euclidean Geometry with LOGO Helen Sims-Coomber and Ralph Martin, Department of Computing Mathematics, University of Wales, College of Cardiff. This article describes a version of LOGO currently under development at Cardiff that uses non-Euclidean geometry. The ultimate aim is that a final version could be given to mathematics students to help them visualise non-Euclidean geometry. The programming language LOGO with its Turtle Graphics facilities is well known in educational circles. The turtle is a small triangular pointer that appears on the display screen. Simple commands are used to move it (FORWARD or BACK) and rotate it (LEFT or RIGHT); it leaves a trail behind it as it moves around the screen. Using the turtle to draw in this way provides an easy introduction to computing for young children, but LOGO is equally suitable for older students. Many sophisticated areas of mathematics (including topology, relativity and differential geometry) can be explored through the use of turtle graphics (see [1]). The system under development at Cardiff is specifically designed for exploring non-Euclidean geometry. Euclidean geometry is the kind taught in schools. Most students will be familiar with the properties of Euclidean parallel lines; given a straight line, L, and a point, P, not on the line, we can construct exactly one line through P parallel to L. The distinguishing feature of non-Euclidean geometry is the behaviour of parallel lines. There are two main types of non-Euclidean geometry: hyperbolic geometry, in which more than one line parallel to L can be constructed, and elliptic geometry, in which parallel lines do not exist at all.

Armstrong , Professor of Computer Aided Engineering, Queen's University Belfast Geometric models form the basis for the construction of domain discretizations used in many computational mechanics simulations. Geometry represents a bottleneck to high-fidelity simulation because of the work required to convert a typical CAD model into the desired analysis model. There are also growing opportunities to use geometry to support advanced techniques like geometry-fitted adaptive mesh refinement, smooth-surface contact detection, and coarsening of mesh models. We invite submissions describing geometric algorithms used during all stages of the mechanics analysis process. Specific areas of interest include, but are not limited to:
