Niven Ring Gravitational Stability Carl A
Niven Ring Gravitational Stability Carl A. Brannen 8500 148th Ave. NE #T-1064, Redmond, WA USA, [email protected] Abstract. A “Niven ring” is a ring of material placed around a star so as to provide a very large inhabitable region. The ring would be solid, about a million miles wide and would be at about earth’s orbit, around 100 million miles from the sun. The ring would be set spinning so that it would provide an equivalent to earth’s gravity field by the action of centrifugal force. Walls a thousand miles high along the edges hold in the atmosphere. The origin of the Niven ring idea is L. Niven’s 1970 novel “Ringworld”. Sometime after writing this book, the author was informed that a Niven ring would be gravitationally unstable. This resulted in further plot development by the author in his 1980 novel, “The Ringworld Engineers”, which describes the efforts necessary to keep the Niven ring orbiting stably. In this short paper we derive the gravitational instability of a Niven ring without calculus. We show that the ring orbit decays exponentially with a time period t of about two months. Keywords: Larry Niven, Ringworld, stability, engineer PACS: 96.15.De, 12.10.Dm 1. INTRODUCTION Larry Niven’s book “Ringworld” [1] describes what is now known as a “Niven ring”, a ring of material surrounding a star at a comfortable (for life) distance, and set in motion so as to provide centrifugal acceleration equivalent to earth’s gravitational field. The orbit of a planet in the gravitational field of the sun is stable, that is, if we make small changes to the orbital parameters this will result in only small changes to the orbit of the planet. -

CYTEEN DOWNLOAD FREE BOOK C. J. Cherryh | 680 pages | 15 Apr 2004 | Little, Brown & Company | 9780446671279 | English | New York, United States Cyteen Series She writes for people who want a long, in-depth read and who aren't afraid of being plunged into Cyteen world full Cyteen new and often confusing Cyteen, ideas, and vocabulary. You can read why I came to this decision here. Extraneous detail, too, which should have been omitted. Cyteen current Talk Cyteen about this Cyteen. ISBN Published by Questar There are so many scenes where Cherryh has CIT characters tell AZIs to perform emotional, sexual and physical labour for them and I have little doubt every time Ari tells Florian to "do something" Cyteen her, Cyteen are reading about rape, and the way Cherryh writes it doesn't hide Cyteen. Mar 24, Margaret rated it really liked it Shelves: fantasy-and- science-fictionauthors-cd. There are plodding sections of political machinations and long stretches of self-analysis and introspection on the part of the main characters Ari and Cyteen. The Cyteen which weren't going anywhere Cyteen long, but had there been content I would be glad to read twice as much. There are a number of political factions in Union's Cyteen, the main ones being the Centrists and the Expansionists. Human colonization has expanded out into the Cyteen, but originally only by slower-than-light travel sponsored by the private Sol Corporation. It just doesn't feel like the 25th century. I even think it's four stars because I was so interested in the character of Ari2. -
THE SURVIVAL and MUTATION of Utoi
PHOENIX RENEWED: THE SURVIVAL AND MUTATION OF UTOi’IAN THOUGHT IN NORTH AMERICAN SCIENCE FICTION, 1965—1982 A DISSERTATION SUBMITTED TO THE FACULTY OF ATLANTA UNIVERSITY IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR TEE DEGREE OF DOCTOR OF PHILOSOPHY BY HODA MOUKHTAR ZAKI DEPARTMENT OF POLITICAL SCIENCE ATLANTA, GEORGIA DECEMBER 1984 ABS TRACT POLITICAL SCIENCE ZAKI, H01P4 MOURHIAR B.A. , American University in Cairo, 1971 N.A., Atlanta University, Atlanta, Georgia, 1974 Phoenix Renewed: The Survival and_Mutation_of Utopian Thought in ~urth American Science Fiction, 1965—1982 Adviser: Dr. Alex Hillingham The&is d~tei Decenber, 1984 This dissertation is concerned with the status of utoni en in rwdcra timas. As such it is concerned with a historic problem ir pci tial :hearv, i.e., how to visualize a perfect human community. Since the turn of the 20th century, we have seen a decline in utopian ~i tera.ture. A variety of commentators, including Mannhein: and Mumford, noted and decried this trend. It seemed ironic to those observers that utopia~s demise would occur when humanity was closest to realizing material abundance for all. My research evaluates this irony. The primary data of my work are drawn from the genre of science fiction. The new locus for utopian thought seems natural enough. Science fiction is a speculative activity and, in its emphasis on science and technology, concerns itself with an area of human activity that has been intimately connected with the idea of progress since the European Enlightenment. A number of scholars including Mumford, Sargent, Suvin, and Williams, have asserted that contemporary utopian thought could be found in science fiction. -
Our University Innovation Is Central to Who We Are and What We Do at the University of California, San Diego
Our University Innovation is central to who we are and what we do at the University of California, San Diego. Here, students learn that knowledge isn’t just acquired in the classroom—life is their laboratory. UC San Diego is an academic powerhouse and economic engine, recognized as one of the top 10 public universities by U.S. News & World Report and ranked number one in the nation for public service by the Washington Monthly. Our location is unparalleled, our impact unmistakable. UC San Diego shapes minds, changes lives, launches industries and builds the future … one student, one discovery and one achievement at a time. Points of Distinction Scripps Institution of Oceanography climate scientist Charles David Keeling was the first to confirm the buildup of carbon dioxide in the atmosphere. His precise measurements, which he began calculating in 1958, produced a data set now known widely as the “Keeling Curve,” a benchmark of global warming studies. The Jacobs School of Engineering is home to the world’s first full-scale outdoor shake table, designed to create realistic simulations of the most devastating earthquakes on record to advance seismic safety. UC San Diego is unique among other UC campuses—our university offers undergraduates the “small college” concept patterned after those at Cambridge and Oxford. Each of the six undergraduate colleges has its own residence halls, student services, traditions and even graduation ceremonies. While the undergraduates remain part of one university, they also develop a sense of identity within the smaller family of their chosen college. In 1986 UC San Diego established the first Cognitive Science Department in the world, which has become one of the leading centers of this field. -

Mirrorshade Women: Feminism and Cyberpunk
Mirrorshade Women: Feminism and Cyberpunk at the Turn of the Twenty-first Century Carlen Lavigne McGill University, Montréal Department of Art History and Communication Studies February 2008 A thesis submitted to McGill University in partial fulfilment of the requirements of the degree of Doctor of Philosophy in Communication Studies © Carlen Lavigne 2008 2 Abstract This study analyzes works of cyberpunk literature written between 1981 and 2005, and positions women’s cyberpunk as part of a larger cultural discussion of feminist issues. It traces the origins of the genre, reviews critical reactions, and subsequently outlines the ways in which women’s cyberpunk altered genre conventions in order to advance specifically feminist points of view. Novels are examined within their historical contexts; their content is compared to broader trends and controversies within contemporary feminism, and their themes are revealed to be visible reflections of feminist discourse at the end of the twentieth century. The study will ultimately make a case for the treatment of feminist cyberpunk as a unique vehicle for the examination of contemporary women’s issues, and for the analysis of feminist science fiction as a complex source of political ideas. Cette étude fait l’analyse d’ouvrages de littérature cyberpunk écrits entre 1981 et 2005, et situe la littérature féminine cyberpunk dans le contexte d’une discussion culturelle plus vaste des questions féministes. Elle établit les origines du genre, analyse les réactions culturelles et, par la suite, donne un aperçu des différentes manières dont la littérature féminine cyberpunk a transformé les usages du genre afin de promouvoir en particulier le point de vue féministe. -
