Time Machine

Wells was interested in the implications of evolutionary theory on the future of human beings at the biological, sociological, and cultural levels, and The Time Machine, short and readable, draws on many of the social and scientific debates of the time. The Broadview edition of this science fiction classic includes extensive materials on Wells’s scientific and political influences.

This book explores the idea of time travel from the first account in English literature to the latest theories of physicists such as Kip Thorne and Igor Novikov. This very readable work covers a variety of topics including: the history of time travel in fiction; the fundamental scientific concepts of time, spacetime, and the fourth dimension; the speculations of Einstein, Richard Feynman, Kurt Goedel, and others; time travel paradoxes, and much more.

For a company that promised to "put a pause on new features," Apple sure has been busy-there's barely a feature left untouched in Mac OS X 10.6 "Snow Leopard." There's more speed, more polish, more refinement-but still no manual. Fortunately, David Pogue is back, with the humor and expertise that have made this the #1 bestselling Mac book for eight years straight. You get all the answers with jargon-free introductions to: Big-ticket changes. A 64-bit overhaul. Faster everything. A rewritten Finder. Microsoft Exchange compatibility. All-new QuickTime Player. If Apple wrote it, this book covers it. Snow Leopard Spots. This book demystifies the hundreds of smaller enhancements, too, in all 50 programs that come with the Mac: Safari, Mail, iChat, Preview, Time Machine. Shortcuts. This must be the tippiest, trickiest Mac book ever written. Undocumented surprises await on every page. Power usage. Security, networking, build-your-own Services, file sharing with Windows, even Mac OS X's Unix chassis-this one witty, expert guide makes it all crystal clear.

Is Windows giving you pause? Ready to make the leap to the Mac instead? There has never been a better time to switch from Windows to Mac, and this incomparable guide will help you make a smooth transition. New York Times columnist and Missing Manuals creator David Pogue gets you past three challenges: transferring your stuff, assembling Mac programs so you can do what you did with Windows, and learning your way around Mac OS X. Learning to use a Mac is not a piece of cake, but once you do, the rewards are oh-so-much better. No viruses, worms, or spyware. No questionable firewalls, inefficient permissions, or other strange features. Just a beautiful machine with a thoroughly reliable system. Whether you're using Windows XP or Vista, we've got you covered. If you're ready to take on Mac OS X Snow Leopard, the latest edition of this bestselling guide tells you everything you need to know: Transferring your stuff -- Moving photos, MP3s, and Microsoft Office documents is the easy part. This book gets you through the tricky things: extracting your email, address book, calendar, Web bookmarks, buddy list, desktop pictures, and MP3 files. Re-creating your software suite -- Big-name programs (Word, Photoshop, Firefox, Dreamweaver, and so on) are available in both Mac and Windows versions, but hundreds of other programs are available only for Windows. This guide identifies the Mac equivalents and explains how to move your data to them. Learning Snow Leopard -- Once you've moved into the Mac, a final task awaits: Learning your way around. Fortunately, you're in good hands with the author of Mac OS X: The Missing Manual, the #1 bestselling guide to the Macintosh. Moving from Windows to a Mac successfully and painlessly is the one thing Apple does not deliver. Switching to the Mac: The Missing Manual, Snow Leopard Edition is your ticket to a new computing experience.

Almost from its inception, Einstein's general theory of relativity was known to sanction spacetime models harboring singularities. Until the 1960s, however, spacetime singularities were thought to be artifacts of the idealizations of the models. This attitude evaporated in the face of a series of theorems, due largely to Stephen Hawking and Roger Penrose, which showed that Einstein's general theory implies that singularities can be expected to occur in a wide variety of conditions in both gravitational collapse and in cosmology. In the light of these results some physicists adopted the attitude that, since spacetime singularities are intolerable, general relativity contains within itself the seeds of its own destruction. Others hoped that peaceful coexistence with singularities could be achieved by proving a form of Roger Penrose's cosmic censorship hypothesis, which would place singularities safely inside black holes. Whatever the attitude one adopts toward spacetime singularities, it is evident that they raise a number of foundational problems for physics and have profound implications for the philosophy of space and time. However, philosophers of science have been slow to awaken to the significance of these developments. Indeed, this is the first serious book-length study of the subject by a philosopher of science. It features an overview of the literature on singularities, as well as an analytic commentary on their significance to a number of scientific and philosophical issues.

H. G. Wells wrote almost a hundred books, yet he is generally remembered for only a handful of them. He is known above all as a writer who heralded the future, yet throughout his life he clung to fixed attitudes from the Victorian past. He began his career as a draper's apprentice; by the age of forty-five he had secured an international reputation as the author of The Time Machine, The War of the Worlds, Kipps and Tono Bungay; he went on to establish himself as an influential educator, polemicist and sage. In this book John Batchelor offers a readable introduction to Wells's huge and varied output as a writer and thinker. He guides the reader through the whole oeuvre, and argues persuasively that at his best Wells was a great artist: a man with a remarkable, restless imagination (not limited, as many critics have implied, merely to his early romances) and with a coherent and responsible theory of fiction.
