At 36,000 feet, Wi-Fi converts our airline seats to remote offices. It lets us read email in airports, watch video in coffee shops, and listen to music at home. Wi-Fi is everywhere. But where did it come from? Wi-Fi and the Bad Boys of Radio takes us back to when the Internet was first gaining popularity, email took ten minutes to load up, and cell phones were big and unwieldy. But Alex Hills had a vision: people carrying small handheld devices that were always connected. His unwavering purpose was to change the way we use the Internet. After being a teenage "ham operator" and bringing radio, TV and telephone service to the Eskimos of northern Alaska, Dr. Hills led a small band of innovators to overcome "the bad boys of radio" - the devilishly unpredictable behavior of radio waves - and build the network that would become the forerunner to today's Wi-Fi. "I know of no one so capable of telling the Wi-Fi story and explaining so clearly how the technology works. Alex Hills is certain to capture the public imagination with this new book." Jim Geier, Principal Consultant, Wireless-Nets, Ltd. and Wi-Fi author "Alex Hills has contributed to the developing world and to developing advanced wireless technology at one of the world's most tech-savvy universities. Working on both frontiers, Dr. Hills pioneered wireless Internet and launched a revolution in the way the world communicates. His story of how we "cut the cord" begins in a place where there were no cords to begin with -- remote Alaska." Mead Treadwell, Lieutenant Governor of Alaska and former Chair, United States Arctic Research Commission Alex Hills is Distinguished Service Professor of Engineering & Public Policy and Electrical & Computer Engineering at Carnegie Mellon University. Dr. Hills is frequently invited to speak at conventions, conferences, university seminars, corporate training sessions, and community events. His talks, with their vivid stories and clear explanations of technology, have been well-received by audiences throughout the United States and in more than twenty foreign countries. An inventor with eleven patents, Dr. Hills can write and speak in technical jargon. But in his writing, as in his talks, he speaks to everyone -- technical specialists and the public alike. People of all backgrounds have been fascinated by his contributions to Scientific American and IEEE Spectrum magazines -- articles that explain technology in a style that is clear to any reader.
From the award-winning author of Parable of the Sower:After the near-extinction of the human race, one young man with extraordinary gifts will reveal whether the human race can learn from its past and rebuild their future . . . or is doomed to self-destruction. In the future, nuclear war has destroyed nearly all humankind. An alien race intervenes, saving the small group of survivors from certain death. But their salvation comes at a cost. The Oankali are able to read and mutate genetic code, and they use these skills for their own survival, interbreeding with new species to constantly adapt and evolve. They value the intelligence they see in humankind but also know that the species—rigidly bound to destructive social hierarchies—is destined for failure. They are determined that the only way forward is for the two races to produce a new hybrid species—and they will not tolerate rebellion. Akin looks like an ordinary human child. But as the first true human-alien hybrid, he is born understanding language, then starts to form sentences at two months old. He can see at a molecular level and kill with a touch. More powerful than any human or Oankali, he will be the architect of both races' future. But before he can carry this new species into the stars, Akin must reconcile with his own heritage in a world already torn in two.
A comprehensive and fascinating account of electrical and electronics history Much of the infrastructure of today's industrialized world arose in the period from the outbreak of World War I to the conclusion of World War II. It was during these years that the capabilities of traditional electrical engineering—generators, power transmission, motors, electric lighting and heating, home appliances, and so on—became ubiquitous. Even more importantly, it was during this time that a new type of electrical engineering—electronics—emerged. Because of its applications in communications (both wire-based and wireless), entertainment (notably radio, the phonograph, and sound movies), industry, science and medicine, and the military, the electronics industry became a major part of the economy. Dawn of the Electronic Age?explores how this engineering knowledge and its main applications developed in various scientific, economic, and social contexts, and explains how each was profoundly affected by electrical technologies. It takes an international perspective and a narrative approach, unfolding the story chronologically. Though a scholarly study (with sources of information given in endnotes for engineers and historians of science and technology), the book is intended for the general public.?Ultimately, it tells the story of the development of a new realm of engineering and its widespread applications during the remarkable and tragic period of two world wars and the decades in between.
So, what would Mary Ann do? As the sweet, polite, and thoughtful Mary Ann Summers from Kansas in the hit series Gilligan’s Island, Dawn Wells created an unforgettable and beloved character that still connects with people fifty years from the show’s debut in 1964. As the “good girl” among the group of castaways on a tiny island, she was often positioned against the glamorous and exotic Ginger Grant, played by Tina Louise, prompting many to ask: Are you a Ginger or a Mary Ann? This book not only helps readers answer that question for themselves but also sends the inspirational and heartwarming message that yes, good girls do finish first. Part self-help, part memoir, and part humor—with a little classic TV nostalgia for good measure—What Would Mary Ann Do? contains twelve chapters on everything from how Mary Ann would respond to changes in today’s culture to addressing issues confronting single women and mothers. Wells brings along her fellow characters from Gilligan’s Island to illustrate certain principles, such as incorporating the miserly Thurston Howell III (Jim Backus) in a discussion on money. Anecdotal sidebars also describe fascinating facts and compelling memories from the show, as well as some trivia questions to challenge fans and followers. Illustrated with photographs from Wells’s private collection, this book provides inspiring lessons from TV’s favorite good girl.

“Stross’s work offers a potent reminder of why short stories used to be the preferred delivery method for science fiction.” – The A.V. Club This selection of speculative fiction runs the gamut—from “Palimpsest,” a decidedly nontraditional time-travel novella, to “Dawn on the Farm,” an adventure of hapless secret agent Bob Howard (star of the Laundry novels: The Atrocity Archives, The Jennifer Morgue, and The Fuller Memorandum). Also included are “MAXOS,” a stunning example of the new flash-fiction form; his Locus Award-winning novella, “Missile Gap”; and “Unwirer,” a collaboration with Cory Doctorow. Rounding out the contents are “A Colder War,” “Rogue Farm,” “Trunk and Disorderly,” and “Snowball’s Chance,” four unique, genre-bending tales that could only come from the limitless imagination of one of the twenty-first century’s most daring visionaries, Charles Stross.
