"My house is the red earth; it could be the center of the world." This is Navajo country, a land of mysterious and delicate beauty. "Stephen Strom's photographs lead you to that place," writes Joy Harjo. "The camera eye becomes a space you can move through into the powerful landscapes that he photographs. The horizon may shift and change all around you, but underneath it is the heart with which we move." Harjo's prose poems accompany these images, interpreting each photograph as a story that evokes the spirit of the Earth. Images and words harmonize to evoke the mysteries of what the Navajo call the center of the world.

From the New York Times–bestselling author of Picture This—a stunning revelation sends a mother and her adopted daughter on a journey of self-discovery. How do you keep a secret so huge that it could devastate everyone you care about? For Kate Malloy, the answer is simple: one lie at a time. That’s how she has protected her daughter for more than a dozen years, shielding her from a terrible truth. Sofia, a fifteen-year-old soccer star living in New England, believes she was born in Mexico and legally adopted by Kate. But a posthumous letter from her stepfather tells Sofia a different story—one of civil unrest and bloodshed, death-defying heroism and child-smuggling, harrowing sacrifice and desperate decisions.\ Sofia’s trust in her mother is shattered. At last Kate must do what she knows is right—accompany Sofia back to Guatemala—the place where Kate found horror and heartache but also the greatest joy of her life. As mother and daughter confront the damage done by years of dangerous yet necessary deceptions, they discover how much love, hope, and happiness may still remain—if they have the courage to face their past.

The family from Secrets of the Garden are back in a new book about backyard science that explains why the seasons change. Alice and her friend Zack explore the reasons for the seasons. Alice's narrative is all about noticing the changes as fall turns into winter, spring, and then summer. She explains how the earth's yearlong journey around the sun, combined with the tilt in the earth's axis, makes the seasons happen. Alice's text is clear and simple, and experiential. Two very helpful—and very funny—chickens give more science details and further explanation through charts, diagrams, and sidebars. Packed with sensory details, humor, and solid science, this book makes a complicated concept completely clear for young readers—and also for the many parents who struggle to answer their kids' questions! "Several adults of my acquaintance . . . would find Secrets of the Seasons to be an eye-popping revelation." —John Lithgow, The New York Times Book Review

How did our universe come to exist? Why do stars shine? Is there life beyond the Earth? For millennia, humans have looked to the celestial sphere to explain the cosmos,first recording the movements of the Moon 25,000 years ago. Since the Enlightenmentand the dawn of the space age, scientists have been unravelling cosmic mysteries, andraising astonishing new questions for future generations to answer. Today we live inan age of unprecedented astronomical revelation, from the discovery of water on Marsto the detection of gravitational waves and the first photograph of a black hole. World-renowned astronomer Paul Murdin explains the science behind these discoveries, along with the passions, strugglesand quirks of fate that made them some of the most intriguing dramas of their times,demonstrating how human ingenuity and technological innovation have expandedour knowledge of the Universe beyond anything our ancestors - even as recently asa generation ago - could ever have imagined.

This anniversary edition which has stood the test of time as a runaway best-seller provides a practical, straight-forward guide to achieving security throughout computer networks. No theory, no math, no fiction of what should be working but isn't, just the facts. Known as the master of cryptography, Schneier uses his extensive field experience with his own clients to dispel the myths that often mislead IT managers as they try to build secure systems. A much-touted section: Schneier's tutorial on just what cryptography (a subset of computer security) can and cannot do for them, has received far-reaching praise from both the technical and business community. Praise for Secrets and Lies "This is a business issue, not a technical one, and executives can no longer leave such decisions to techies. That's why Secrets and Lies belongs in every manager's library."-Business Week "Startlingly lively....a jewel box of little surprises you can actually use."-Fortune "Secrets is a comprehensive, well-written work on a topic few business leaders can afford to neglect."-Business 2.0 "Instead of talking algorithms to geeky programmers, [Schneier] offers a primer in practical computer security aimed at those shopping, communicating or doing business online-almost everyone, in other words."-The Economist "Schneier...peppers the book with lively anecdotes and aphorisms, making it unusually accessible."-Los Angeles Times With a new and compelling Introduction by the author, this premium edition will become a keepsake for security enthusiasts of every stripe.

With its clear skies and low humidity, the southwestern United States is an astronomer’s paradise where observatories like Kitt Peak have redefined the art of skywatching. The region is unique in its loose federation of like-minded research outposts and in the quantity and diversity of its observatories—places captured in this unique guidebook. Douglas Isbell and Stephen Strom, both intimately involved in southwestern astronomy, have written a practical guide to the major observatories of the region for those eager to learn what modern telescopes are doing, to understand the role each of these often quirky places has played in advancing our understanding of the cosmos, and hopefully to visit and see the tools of the astronomer up close. For each observatory, the authors describe its history, highlights of its contributions to astronomy—with an emphasis on recent results—and information for visitors. Also included are wide-ranging interviews with astronomers closely associated with each site. Observatories covered range from McDonald in Texas to Palomar in California, with significant outposts in between: Arizona’s Kitt Peak National Observatory southwest of Tucson, the Lowell Observatory in Flagstaff, and the Whipple Observatory outside Amado; and New Mexico’s Very Large Array near Socorro and Sacramento Peak close to Sunspot. In addition to describing these established institutions, they also take a look ahead to the most powerful ground-based telescope in the world just beginning to operate at full power on Mount Graham in Safford, Arizona. With more than three dozen illustrations, Observatories of the Southwest is accessible to amateur astronomers, tourists, students, and teachers—anyone fascinated with the contributions that astronomy has made to deepening our understanding of humanity’s place in the universe, whether exploring the solar system from Lowell Observatory or studying the birth of stars using the army of giant radio telescopes at the Very Large Array. This book aims to inspire visits to these sites by illuminating the major scientific questions being pursued every clear night beneath the dark skies of the Southwest and the amazing machinery that makes these pursuits possible.
