Introduction - 10,000 Year Clock

Introduction - 10,000 Year Clock
The full scale 10,000 Year Clock is now under construction. While there is no completion date scheduled, we do plan to open it to the public once it is ready. The essay below by Long Now board member Kevin Kelly discusses what we hope the Clock will be once complete. This is one of several projects by Long Now to creatively foster long-term thinking in the context of the next 10,000 years. by Kevin Kelly There is a Clock ringing deep inside a mountain. is around to hear it. The Clock is real. The Clock is now being machined and assembled in California and Seattle. The Clock’s inventor introduced the idea of the Clock (in 01995) with this context: I cannot imagine the future, but I care about it. That’s Danny Hillis, a polymath inventor, computer engineer, and designer, inventor and prime genius of the Clock. Eno also composed the never-repeating melody generator that rings the Clock’s chimes inside the mountain. To see the Clock you need to start at dawn, like any pilgrimage.

Terminal Event Management Policy The Terminal Event Management Policy (TEMP) is an official policy of Wikipedia detailing the procedures to be followed to safeguard the content of the encyclopedia in the event of a non-localized event that would render the continuation of Wikipedia in its current form untenable. The policy is designed to facilitate the preservation of the encyclopedia by a transition to non-electronic media in an orderly, time-sensitive manner or, if events dictate otherwise, the preservation of the encyclopedia by other means. Editors are asked to familiarize themselves with the procedures and in the unlikely event that the implementation of these procedures proves necessary, act in accordance with the procedural guidelines, inasmuch as circumstances allow. About the policy[edit]

Asteroid spectral types Asteroids are assigned a type based on spectral shape, color, and sometimes albedo. These types are thought to correspond to an asteroid's surface composition. For small bodies that are not internally differentiated, the surface and internal compositions are presumably similar, while large bodies such as 1 Ceres and 4 Vesta are known to have internal structure.

Access Denied Machines: Global Village Construction Set The Global Village Construction Set (GVCS) is a modular, DIY, low-cost, high-performance platform that allows for the easy fabrication of the 50 different Industrial Machines that it takes to build a small, sustainable civilization with modern comforts. We’re developing open source industrial machines that can be made at a fraction of commercial costs, and sharing our designs online for free. We are developing a lifesize, scalable, modular LEGO construction set. The GVCS in itself consists of many other Construction Sets – as we build not individual machines, but construction sets of machines.

Anexo:Asteroides Lo que sigue son las tablas que componen el catálogo de asteroides dadas en orden secuencial. Hasta noviembre de 2014 había 415 688 [1] asteroides numerados y 248 348 [2] más sin numerar, la mayoría de ellos sin características destacables, mientras que los que habían recibido denominación definitiva asciendían a 18 977 [3]. El asteroide con menor número que aún no ha recibido nombre definitivo es (3708) 1974 FV1. El catálogo incluye todos los objetos del sistema solar que no son planetas (y sus satélites) o cometas. Cinco cuerpos de esta lista han sido catalogados también como planetas enanos. En grupos de 1000[editar]

Tux Factory - CrystalXP.net Preserving human knowledge: similar projects - The Knowledge The notion of preserving human knowledge for posterity, in sum total or at least a condensed summary of the key principles, in case of a cataclysm that collapses civilisation is not a new one. As discussed more fully in the History of the Total Book blogpost, eighteenth-century encyclopaedia compilers were conscious of the fragility of past empires and made efforts to catalogue and preserve crucial information for society in the aftermath of a great catastrophe. One of the inspirations for me to begin researching and writing The Knowledge on this theme was James Lovelock’s 1998 essay on the threats to our modern civilisation and the necessity for a ‘Book for All Seasons’. And there have been a number of other, similar propositions since then. Kevin Kelly, a former editor of the Whole Earth Catalog and founder of Wired magazine, proposed the ‘Forever Book’ in 2004 and the ‘Library of Utility’ in 2011 – a remote mountain-top vault of books.

Albedo La nieve tiene el albedo más alto de la superficie terrestre. El albedo es el porcentaje de radiación que cualquier superficie refleja respecto a la radiación que incide sobre la misma. Las superficies claras tienen valores de albedo superiores a las oscuras, y las brillantes más que las mates. El albedo medio de la Tierra es del 37-39% de la radiación que proviene del Sol. Es una medida de la tendencia de una superficie a reflejar radiación incidente. ‘Most crucial scientific knowledge’ preserved in academic’s guidebook for end of the world University of Leicester astrobiologist highlights importance of understanding fundamental science in new book Issued by University of Leicester Press Office on 2 April 2014 Image of book cover and photographs of Lewis Dartnell available from: pt91@le.ac.uk Book launch: Wednesday 9 April at 6.30pm, at Lutyens & Rubinstein, 21 Kensington Park Road, London, W11 2EU.

Tipo espectral (asteroides) La clasificación actual fue iniciada por Clark R. Chapman, David Morrison y Ben Zellner en 1975[1] con las tres categorías Tipo C para los objetos carbonaceos, Tipo S para objetos duros (silicatos), y Tipo U para los objetos que no tenían cabida en las categorías C o S. Esta clasificación ha sido expandida y clarificada. Una cantidad de clasificaciones están actualmente en existencia,[2] [3] y mientras ellas se esfuerzan en mantener algo de mutua consistencia, algunos pocos asteroides son ordenados en diferentes clases dependiendo del esquema en particular.

After an Apocalypse, What's Left of Digital Stores of Knowledge? The editor of the Gawker media sci-fi blog io9, Annalee Newitz, is working on a book about how humans will regroup after the apocalypse. That such a book could be considered non-fiction is a remarkable commentary on the world we live in, with gold at a record high, the U.S. government on the verge of default, supplies of cheap oil running out and the environment crashing down on the heads of more humans than anyone ever imagined could simultaneously inhabit spaceship earth. It’s tempting to believe that we live in a special time – this is the root of all apocalyptic thinking – but it’s hard to compare even today’s menaces to the rise of the Third Reich, the fall of the Roman Empire or the Black Death. At least not yet.

Álgebra de Virasoro El álgebra de Virasoro es una forma de álgebra de Lie compleja, dada como extensión central del campo vectorial de los polinomios complejos sobre la circunferencia unitaria; esta álgebra toma su nombre del físico argentino Miguel Ángel Virasoro (n. 1940). Es muy usada en teoría de las cuerdas. Definición[editar] El álgebra de Virasoro es una cobertura lineal de los elementos: para , con: Bubblegram A laser glass sculpture of a caffeine molecule A bubblegram (a.k.a. laser crystal, 3D crystal engraving or vitrography) is a solid block of glass or transparent plastic that have been exposed to laser beams to generate three-dimensional designs inside. The image is composed of many small points of fracture or other visible deformation and appears to float inside the block.

Ciclo de Carnot [actualizar] Esquema de una máquina de Carnot. La máquina absorbe calor desde la fuente caliente T1 y cede calor a la fría T2 produciendo trabajo. y, como se verá adelante, es mayor que cualquier máquina que funcione cíclicamente entre las mismas fuentes de temperatura. Una máquina térmica que realiza este ciclo se denomina máquina de Carnot.
