  • The Being of Analogy Noah Roderick Noah Roderick the Being of Analogy
    Noah Roderick The Being of Analogy Noah Roderick Noah Roderick The Being of Analogy The Being of Modern physics replaced the dualism of matter and form with a new distinction between matter and force. In this way form was marginalized, and with it the related notion of the object. Noah Roderick’s book is a refreshing effort to reverse the consequences of this now banal mainstream materialism. Ranging from physics through literature to linguistics, spanning philosophy from East to West, and weaving it all together in remarkably lucid prose, Roderick intro- duces a new concept of analogy that sheds unfamiliar light on such thinkers as Marx, Deleuze, Goodman, Sellars, and Foucault. More than a literary device, analogy teaches us something about being itself. OPEN HUMANITIES PRESS Cover design by Katherine Gillieson · Illustration by Tammy Lu The Being of Analogy New Metaphysics Series Editors: Graham Harman and Bruno Latour The world is due for a resurgence of original speculative metaphysics. The New Metaphys- ics series aims to provide a safe house for such thinking amidst the demoralizing caution and prudence of professional academic philosophy. We do not aim to bridge the analytic- continental divide, since we are equally impatient with nail-filing analytic critique and the continental reverence for dusty textual monuments. We favor instead the spirit of the intel- lectual gambler, and wish to discover and promote authors who meet this description. Like an emergent recording company, what we seek are traces of a new metaphysical ‘sound’ from any nation of the world. The editors are open to translations of neglected metaphysical classics, and will consider secondary works of especial force and daring.

  • Was the Eruption of Ferdinandea, Near Sicily, One of the Largest Volcanic Climate Forcing Events of the Nineteenth Century?
    https://doi.org/10.5194/cp-2021-78 Preprint. Discussion started: 5 August 2021 c Author(s) 2021. CC BY 4.0 License. The blue suns of 1831: was the eruption of Ferdinandea, near Sicily, one of the largest volcanic climate forcing events of the nineteenth century? 5 Christopher Garrison1, Christopher Kilburn1, David Smart 1, Stephen Edwards 1. 1 UCL Hazard Centre, Department of Earth Sciences, University College London, Gower Street, London, WC1E 6BT, UK. Correspondence to: Christopher Garrison ([email protected]) Abstract. One of the largest climate forcing eruptions of the nineteenth century was, until recently, 10 believed to have taken place at Babuyan Claro volcano, in the Philippines, in 1831. However, a recent investigation found no reliable evidence of such an eruption, suggesting that the 1831 eruption must have taken place elsewhere. A newly compiled dataset of reported observations of a blue, purple and green sun in August 1831 is here used to reconstruct the transport of a stratospheric aerosol plume from that eruption. The source of the aerosol plume is identified as the eruption of Ferdinandea, which took place 15 about 50 km off the south-west coast of Sicily (lat. 37.1o N., long. 12.7o E.), in July and August 1831. The modest magnitude of this eruption, assigned a Volcanic Explosivity Index (VEI) of 3, has commonly caused it to be discounted or overlooked when identifying the likely source of the stratospheric sulphate aerosol in 1831. It is proposed, however, that convective instability in the troposphere contributed to aerosol reaching the stratosphere and that the aerosol load was enhanced by addition of a sedimentary 20 sulphur component to the volcanic plume.

  • Summary of Sexual Abuse Claims in Chapter 11 Cases of Boy Scouts of America
    Summary of Sexual Abuse Claims in Chapter 11 Cases of Boy Scouts of America There are approximately 101,135sexual abuse claims filed. Of those claims, the Tort Claimants’ Committee estimates that there are approximately 83,807 unique claims if the amended and superseded and multiple claims filed on account of the same survivor are removed. The summary of sexual abuse claims below uses the set of 83,807 of claim for purposes of claims summary below.1 The Tort Claimants’ Committee has broken down the sexual abuse claims in various categories for the purpose of disclosing where and when the sexual abuse claims arose and the identity of certain of the parties that are implicated in the alleged sexual abuse. Attached hereto as Exhibit 1 is a chart that shows the sexual abuse claims broken down by the year in which they first arose. Please note that there approximately 10,500 claims did not provide a date for when the sexual abuse occurred. As a result, those claims have not been assigned a year in which the abuse first arose. Attached hereto as Exhibit 2 is a chart that shows the claims broken down by the state or jurisdiction in which they arose. Please note there are approximately 7,186 claims that did not provide a location of abuse. Those claims are reflected by YY or ZZ in the codes used to identify the applicable state or jurisdiction. Those claims have not been assigned a state or other jurisdiction. Attached hereto as Exhibit 3 is a chart that shows the claims broken down by the Local Council implicated in the sexual abuse.

  • Lunar Pole Illumination and Communications Maps Computed from Goldstone Solar System Radar Elevation Data
    IPN Progress Report 42-176 • February 15, 2009 Lunar Pole Illumination and Communications Maps Computed from Goldstone Solar System Radar Elevation Data Scott Bryant* The Goldstone Solar System Radar (GSSR) group at JPL produced a digital elevation model (DEM) of the lunar south pole using data obtained in 2006. This new DEM has 40-m hori- zontal resolution and about 5-m relative vertical accuracy. This article explains how this DEM was used to evaluate average solar illumination and Earth visibility near the lunar south pole. The elevation data were converted into local terrain horizon masks for the area within 100 km of the lunar south pole. These topocentric horizon masks were converted into selenographic latitude and longitude coordinates, then compared to regions bound- ing the maximum Sun and Earth motions relative to the Moon. Estimates of Earth visibility were computed by integrating the area of the region bounding the Earth’s motion that was below the horizon mask. Solar illumination and other metrics were computed similarly. Proposed lunar south pole base sites are examined in detail, with the best site showing multiyear averages of solar power availability of 92 percent and direct-to-Earth (DTE) com- munication availability of 51 percent. Results are compared with a theoretical model and with actual Sun and Earth visibility averaged over the years 2009 to 2028. Peaks near the lunar south pole with continuous DTE communications are also presented. Results for the lunar north pole were computed using the GSSR DEM of the lunar north pole produced in 1997. The article also explores using a heliostat to reduce the photovoltaic power system mass and complexity.
