Intelligent Design, Abiogenesis, and Learning from History: Dennis R
Author Exchange Intelligent Design, Abiogenesis, and Learning from History: Dennis R. Venema A Reply to Meyer Dennis R. Venema Weizsäcker’s book The World View of Physics is still keeping me very busy. It has again brought home to me quite clearly how wrong it is to use God as a stop-gap for the incompleteness of our knowledge. If in fact the frontiers of knowledge are being pushed back (and that is bound to be the case), then God is being pushed back with them, and is therefore continually in retreat. We are to find God in what we know, not in what we don’t know; God wants us to realize his presence, not in unsolved problems but in those that are solved. Dietrich Bonhoeffer1 am thankful for this opportunity to nature, is the result of intelligence.

Meyer’s origin of biological information: if infor- critiques of my review fall into two gen- mation only ever arises from intelli- eral categories. First, he claims I mistook gence, then the mere presence of Signature for an argument against bio- information demonstrates design. A few logical evolution, rendering several of examples from Signature make the point my arguments superfluous. Secondly, easily: Meyer asserts that I have failed to refute … historical scientists can show that his thesis by not providing a “causally a presently acting cause must have adequate alternative explanation” for the been present in the past because the origin of life in that the few relevant cri- proposed candidate is the only known tiques I do provide are “deeply flawed.” cause of the effect in question. -
A Time of Great Growth
Newsletter | Spring 2019 A Time of Great Growth Heartfelt greetings from the UC Riverside Department of Physics and Astronomy. This is our annual newsletter, sent out each Spring to stay connected with our former students, retired faculty, and friends in the wider community. The Department continues to grow, not merely in size but also in stature and reputation. For the 2018-2019 academic year, we were pleased to welcome two new faculty: Professors Thomas Kuhlman and Barry Barish. Professor Kuhlman was previously on the faculty at the University of Illinois at Urbana-Champaign. He joins our efforts in the emerging field of biophysics. His research lies in the quantitative imaging and theoretical modeling of biological systems. He works on genome dynamics, quantification of the activity of transposable elements in living cells, and applications to the engineering of genome editing. Professor Barry Barish, who joins us from Caltech, is the winner of the 2017 Nobel Prize in Physics. He brings great prestige to our Department. Along with Professor Richard Schrock of the Department of Chemistry, who also joined UCR in 2018, UCR now has two Nobel Prize winners on its faculty. Professor Barish is an expert on the detection and physics of gravitational waves. He has been one of the key figures in the conception, construction, and operation of the LIGO detector, where gravitational waves were first discovered in 2015, and which led to his Nobel Prize. He is a member of the National Academy of Sciences and the winner of many other prestigious awards. The discovery of gravitational waves is one of the most exciting developments in physics so far this century. -

Saad Ghafar and Amir Sultan Khan Department of Mathematics, Kohat University of Science and Technology, Kohat 26000, Pakistan; [email protected] (F.A.); [email protected] (A.S.); [email protected] (M.S.G.); [email protected] (A.S.K.) * Correspondence: [email protected] Received: 5 December 2018; Accepted: 22 January 2019; Published: 13 February 2019 Abstract: This research provides second-order approximate Noether symmetries of geodetic Lagrangian of time-conformal plane symmetric spacetime. A time-conformal factor is of the form ee f (t) which perturbs the plane symmetric static spacetime, where e is small a positive parameter that produces perturbation in the spacetime. By considering the perturbation up to second-order in e in plane symmetric spacetime, we find the second order approximate Noether symmetries for the corresponding Lagrangian. Using Noether theorem, the corresponding second order approximate conservation laws are investigated for plane symmetric gravitational waves like spacetimes. This technique tells about the energy content of the gravitational waves. Keywords: Einstein field equations; time conformal spacetime; approximate conservation of energy 1. Introduction Gravitational waves are ripples in the fabric of space-time produced by some of the most violent and energetic processes like colliding black holes or closely orbiting black holes and neutron stars (binary pulsars). These waves travel with the speed of light and depend on their sources [1–5]. The study of these waves provide us useful information about their sources (black holes and neutron stars). -

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. -

Ripples in Spacetime
editorial Ripples in spacetime The 2017 Nobel prize in Physics has been awarded to Rainer Weiss, Barry C. Barish and Kip S. Thorne “for decisive contributions to the LIGO detector and the observation of gravitational waves”. It is, frankly, difficult to find something original to say about the detection of gravitational waves that hasn’t been said already. The technological feat of measuring fluctuations in the fabric of spacetime less than one-thousandth the width of an atomic nucleus is quite simply astonishing. The scientific achievement represented by the confirmation of a century-old prediction by Albert Einstein is unique. And the collaborative effort that made the discovery possible — the Laser Interferometer Gravitational-Wave Observatory (LIGO) — is inspiring. Adapted from Phys. Rev. Lett. 116, 061102 (2016), under Creative Commons Licence.

Title: the Distribution of an Illustrated Timeline Wall Chart and Teacher's Guide of 20Fh Century Physics
REPORT NSF GRANT #PHY-98143318 Title: The Distribution of an Illustrated Timeline Wall Chart and Teacher’s Guide of 20fhCentury Physics DOE Patent Clearance Granted December 26,2000 Principal Investigator, Brian Schwartz, The American Physical Society 1 Physics Ellipse College Park, MD 20740 301-209-3223 [email protected] BACKGROUND The American Physi a1 Society s part of its centennial celebration in March of 1999 decided to develop a timeline wall chart on the history of 20thcentury physics. This resulted in eleven consecutive posters, which when mounted side by side, create a %foot mural. The timeline exhibits and describes the millstones of physics in images and words. The timeline functions as a chronology, a work of art, a permanent open textbook, and a gigantic photo album covering a hundred years in the life of the community of physicists and the existence of the American Physical Society . Each of the eleven posters begins with a brief essay that places a major scientific achievement of the decade in its historical context. Large portraits of the essays’ subjects include youthful photographs of Marie Curie, Albert Einstein, and Richard Feynman among others, to help put a face on science. Below the essays, a total of over 130 individual discoveries and inventions, explained in dated text boxes with accompanying images, form the backbone of the timeline. For ease of comprehension, this wealth of material is organized into five color- coded story lines the stretch horizontally across the hundred years of the 20th century. The five story lines are: Cosmic Scale, relate the story of astrophysics and cosmology; Human Scale, refers to the physics of the more familiar distances from the global to the microscopic; Atomic Scale, focuses on the submicroscopic This report was prepared as an account of work sponsored by an agency of the United States Government. -

The History of Lasers at Stanford Group
Lasers at 50: Byer The History of Lasers at Stanford Group Robert L. Byer Applied Physics Stanford University [email protected] Abstract In the fifty years since the demonstration of the laser, coherent light has changed the way we work, communicate and play. The generation and control of light is critical for meeting important challenges of the 21st century from fundamental science to the generation of energy. A look back at the early days of the laser at Stanford will be contrasted to the recent breakthroughs in solid state lasers and the applications to fundamental science of gravitational wave detection, remote sensing, and laser induced fusion for energy production.
