In "The Worlds of If," author Stanley Weinbaum plays with a concept that has been at the center of countless science fiction tales before and after: how the most minute shifts can alter the past, present and future. In this case, nutty professor Haskel van Manderpootz invents a contraption that allows users to view alternate life paths that might have transpired if they had made different choices along the way.

From the #1 New York Times bestselling author of Anathem, Reamde, and Cryptonomicon comes an exciting and thought-provoking science fiction epic—a grand story of annihilation and survival spanning five thousand years. What would happen if the world were ending? A catastrophic event renders the earth a ticking time bomb. In a feverish race against the inevitable, nations around the globe band together to devise an ambitious plan to ensure the survival of humanity far beyond our atmosphere, in outer space. But the complexities and unpredictability of human nature coupled with unforeseen challenges and dangers threaten the intrepid pioneers, until only a handful of survivors remain . . . Five thousand years later, their progeny—seven distinct races now three billion strong—embark on yet another audacious journey into the unknown . . . to an alien world utterly transformed by cataclysm and time: Earth. A writer of dazzling genius and imaginative vision, Neal Stephenson combines science, philosophy, technology, psychology, and literature in a magnificent work of speculative fiction that offers a portrait of a future that is both extraordinary and eerily recognizable. As he did in Anathem, Cryptonomicon, the Baroque Cycle, and Reamde, Stephenson explores some of our biggest ideas and perplexing challenges in a breathtaking saga that is daring, engrossing, and altogether brilliant.

This unusual picture book shrinks the world's population down to a village of 100 to help children better understand who we are, where we live, how fast we are growing and more. "Thought-provoking and highly effective, this world-in-miniature will open eyes to a wider view of our planet and its human inhabitants."

Scientists are building rocket ships for a chosen few to escape planets hurtling toward each other on a direct collision course, leaks out touching off a savage struggle for survival.

"In the face of the most perilous challenges of our time--climate change, terrorism, poverty, and trafficking of drugs, guns, and people--the nations of the world seem paralyzed. The problems are too big for governments to deal with. Benjamin Barber contends that cities, and the mayors who run them, can do and are doing a better job than nations. He cites the unique qualities cities worldwide share: pragmatism, civic trust, participation, indifference to borders and sovereignty, and a democratic penchant for networking, creativity, innovation, and cooperation. He demonstrates how city mayors, singly and jointly, are responding to transnational problems more effectively than nation-states mired in ideological infighting and sovereign rivalries. The book features profiles of a dozen mayors around the world, making a persuasive case that the city is democracy's best hope in a globalizing world, and that great mayors are already proving that this is so"--

"No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's..." So begins H. G. Wells' classic novel in which Martian lifeforms take over planet Earth. As the Martians emerge, they construct giant killing machines - armed with heatrays - that are impervious to attack. Advancing upon London they destroy everything in their path. Everything, except the few humans they collect in metal traps. Victorian England is a place in which the steam engine is state-of-the-art technology and powered flight is just a dream. Mankind is helpless against the killing machines from Mars, and soon the survivors are left living in a new stone age. Includes the original Warwick Goble illustrations.

I guess I always felt even if the world came to an end, McDonald's still would be open. High school sophomore Miranda's disbelief turns to fear in a split second when an asteroid knocks the moon closer to Earth, like "one marble hits another." The result is catastrophic. How can her family prepare for the future when worldwide tsunamis are wiping out the coasts, earthquakes are rocking the continents, and volcanic ash is blocking out the sun? As August turns dark and wintery in northeastern Pennsylvania, Miranda, her two brothers, and their mother retreat to the unexpected safe haven of their sunroom, where they subsist on stockpiled food and limited water in the warmth of a wood-burning stove. Told in a year's worth of journal entries, this heart-pounding story chronicles Miranda's struggle to hold on to the most important resource of all--hope--in an increasingly desperate and unfamiliar world. An extraordinary series debut Susan Beth Pfeffer has written several companion novels to Life As We Knew It, including The Dead and the Gone, This World We Live In, and The Shade of the Moon.
