Available in PDF, EPUB and Kindle. Book excerpt: Creating the Sinclair ZX Spectrum Vega describes how the four founders of Retro Computers came together to create a unique games console: the Sinclair ZX Spectrum Vega. Sir Clive Sinclair, the world famous inventor, caused a technological revolution in the early 1980s when he launched the ZX Spectrum, a low-cost colour home computer that found its way into millions of households throughout the UK, Spain, Russia and many other countries across the world. The Spectrum proved so successful that more than twenty thousand games, utilities and educational titles were written for it, many of which are remembered fondly to this very day. When the Retro Computers team released the Vega, a modern interpretation of that original ZX Spectrum, one thousand of these much-loved games were pre-loaded on the console; obtaining the rights to these is just one part of the fascinating story that this book tells: the genesis, conception and development of the Sinclair ZX Spectrum Vega.

Download or read book Random Graph Dynamics written by Rick Durrett and published by Cambridge University Press. This book was released on 2010-05-31 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theory of random graphs began in the late 1950s in several papers by Erdos and Renyi. In the late twentieth century, the notion of six degrees of separation, meaning that any two people on the planet can be connected by a short chain of people who know each other, inspired Strogatz and Watts to define the small world random graph in which each site is connected to k close neighbors, but also has long-range connections. At a similar time, it was observed in human social and sexual networks and on the Internet that the number of neighbors of an individual or computer has a power law distribution. This inspired Barabasi and Albert to define the preferential attachment model, which has these properties. These two papers have led to an explosion of research. The purpose of this book is to use a wide variety of mathematical argument to obtain insights into the properties of these graphs. A unique feature is the interest in the dynamics of process taking place on the graph in addition to their geometric properties, such as connectedness and diameter.

Download or read book The Originality of the Avant Garde and Other Modernist Myths written by Rosalind E. Krauss and published by MIT Press. This book was released on 1986-07-09 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Co-founder and co-editor of October magazine, a veteran of Artforum of the 1960s and early 1970s, Rosalind Krauss has presided over and shared in the major formulation of the theory of postmodernism. In this challenging collection of fifteen essays, most of which originally appeared in October, she explores the ways in which the break in style that produced postmodernism has forced a change in our various understandings of twentieth-century art, beginning with the almost mythic idea of the avant-garde. Krauss uses the analytical tools of semiology, structuralism, and poststructuralism to reveal new meanings in the visual arts and to critique the way other prominent practitioners of art and literary history write about art. In two sections, "Modernist Myths" and "Toward Postmodernism," her essays range from the problem of the grid in painting and the unity of Giacometti's sculpture to the works of Jackson Pollock, Sol Lewitt, and Richard Serra, and observations about major trends in contemporary literary criticism.

Download or read book Protocols in Lichenology written by Ilse Kranner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: As an intricate association between a fungus and one or more green algae or cyanobacteria, lichens are one of the most successful examples of symbiosis. These fascinating organisms survive extreme desiccation and temperatures. They are adapted to a great variety of habitats, from deserts to intertidal zones, from tropical rain forests to the peaks of the Himalayas and to circumpolar ecosystems. Lichens are extremely efficient accumulators of atmospherically deposited pollutants, and are therefore widely used to monitor environmental pollution. Their wide range of secondary products show pharmaceutically interesting fungicidal, antibacterial and antiviral properties. Lichens are extremely difficult to culture. This manual provides well-tested tissue culture protocols, protocols for studying lichen ultrastructure, (eco)physiology, primary and secondary compounds, and for using lichens as bioindicators.

Download or read book Electronic Dreams written by Tom Lean and published by Bloomsbury Publishing. This book was released on 2016-02-11 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did computers invade the homes and cultural life of 1980s Britain? Remember the ZX Spectrum? Ever have a go at programming with its stretchy rubber keys? How about the BBC Micro, Acorn Electron, or Commodore 64? Did you marvel at the immense galaxies of Elite, master digital kung-fu in Way of the Exploding Fist or lose yourself in the surreal caverns of Manic Miner? For anyone who was a kid in the 1980s, these iconic computer brands are the stuff of legend. In Electronic Dreams, Tom Lean tells the story of how computers invaded British homes for the first time, as people set aside their worries of electronic brains and Big Brother and embraced the wonder-technology of the 1980s. This book charts the history of the rise and fall of the home computer, the family of futuristic and quirky machines that took computing from the realm of science and science fiction to being a user-friendly domestic technology. It is a tale of unexpected consequences, when the machines that parents bought to help their kids with homework ended up giving birth to the video games industry, and of unrealised ambitions, like the ahead-of-its-time Prestel network that first put the British home online but failed to change the world. Ultimately, it's the story of the people who made the boom happen, the inventors and entrepreneurs like Clive Sinclair and Alan Sugar seeking new markets, bedroom programmers and computer hackers, and the millions of everyday folk who bought in to the electronic dream and let the computer into their lives.
