Henry Petroski's previous bestsellers have delighted readers with intriguing stories about the engineering marvels around us, from the lowly pencil to the soaring suspension bridge. In this book, Petroski delves deeper into the mystery of invention, to explore what everyday artifacts and sophisticated networks can reveal about the way engineers solve problems.

Engineering entails more than knowing the way things work. What do economics and ecology, aesthetics and ethics, have to do with the shape of a paper clip, the tab of a beverage can, the cabin design of a turbojet, or the course of a river? How do the idiosyncrasies of individual engineers, companies, and communities leave their mark on projects from Velcro® to fax machines to waterworks?Invention by Design offers an insider's look at these political and cultural dimensions of design and development, production and construction.

Readers unfamiliar with engineering will find Petroski's enthusiasm contagious, whether the topic is the genesis of the Ziploc baggie or the averted collapse of Manhattan's sleekest skyscraper. And those who inhabit the world of engineering will discover insights to challenge their customary perspective, whether their work involves failure analysis, systems design, or public relations. Written with the flair that readers have come to expect from his books, Invention by Design reaffirms Petroski as the master explicator of the principles and processes that turn thoughts into the many things that define our made world.

No other text on the market today can match the success of Halliday, Resnick and Walker’s Fundamentals of Physics This text continues to outperform the competition year after year, and the new edition will be no exception.  Intended for Calculus-based Physics courses, the 6th edition of this extraordinary text is a major redesign of the best-selling 5th edition, which still maintains many of the elements that led to its enormous success.  Jearl Walker adds his unique style to this edition with the addition of new problems designed to capture, and keep, students’ attention.  Nearly all changes are based on suggestions from instructors and students using the 5th edition, from reviewer comments, and from research done on the process of learning.  The primary goal of this text is to provide students with a solid understanding of fundamental physics concepts, and to help them apply this conceptual understanding to quantitative problem solving.

The principal goal of Halliday-Resnick-Walker is to provide instructors with a tool by which they can teach students how to effectively read scientific material and successfully reason through scientific questions. To sharpen this tool, the Enhanced Problems Version of the sixth edition of Fundamentals of Physics contains over 1000 new, high-quality problems that require thought and reasoning rather than simplistic plugging of data into formulas..

How is the human brain like the AIDS epidemic? Ask physicist Albert-László Barabási and he'll explain them both in terms of networks of individual nodes connected via complex but understandable relationships. Linked: The New Science of Networks is his bright, accessible guide to the fundamentals underlying neurology, epidemiology, Internet traffic, and many other fields united by complexity.

Barabási's gift for concrete, nonmathematical explanations and penchant for eccentric humor would make the book thoroughly enjoyable even if the content weren't engaging. But the results of Barabási's research into the behavior of networks are deeply compelling. Not all networks are created equal, he says, and he shows how even fairly robust systems like the Internet could be crippled by taking out a few super-connected nodes, or hubs. His mathematical descriptions of this behavior are helping doctors, programmers, and security professionals design systems better suited to their needs. Linked presents the next step in complexity theory--from understanding chaos to practical applications. --Rob Lightner.

Demon Doppelgangers

Ancient powers give evil rise

and open up demon eyes.

Find the answer, quell the curse --

or things will surely get much worse...

Paige has a new job -- and it's perfect for her. She's working at a museum, conducting tours through a traveling Grecian display. It's temporary, but it's better than nothing, and it means she gets to see Chase, a really hot guy who started working at the museum at about the same time she did. One day, though, a big stone ovoid meant to represent a dragon's egg turns up, and it gives her the creeps. When Paige asks Phoebe and Piper to come check it out, they agree there's definitely something evil about that weird old egg.

Later, after a long day of tours, Paige and Chase relax near the artifact. Without warning, Chase, who knows only a few Greek words, begins speaking in the language. His monologue opens the egg, releasing a demon that promptly assumes Chase's form. When Paige tries to kill it, it splits in half, forming two identical Chases. With the real Chase unable to explain what happened and demons on the loose, the Charmed Ones will have to count on the Power of Three to figure out what's doubling these demons...and why.

“The Icarus Girl is an astonishing achievement.” —Sunday Telegraph (London)

Jessamy “Jess” Harrison is eight years old. Sensitive, whimsical, possessed of an extraordinary and powerful imagination, she spends hours writing haiku, reading Shakespeare, or simply hiding in the dark warmth of the airing cupboard. As the child of an English father and a Nigerian mother, Jess just can’t shake off the feeling of being alone wherever she goes, and the other kids in her class are wary of her tendency to succumb to terrified fits of screaming. Believing that a change from her English environment might be the perfect antidote to Jess’s alarming mood swings, her parents whisk her off to Nigeria for the first time where she meets her mother’s family—including her formidable grandfather.

Jess’s adjustment to Nigeria is only beginning when she encounters Titiola, or TillyTilly, a ragged little girl her own age. To Jess, it seems that, at last, she has found someone who will understand her. But gradually, TillyTilly’s visits become more disturbing, making Jess start to realize that she doesn’t know who TillyTilly is at all.

Helen Oyeyemi draws on Nigerian mythology to present a strikingly original variation on a classic literary theme: the existence of "doubles," both real and spiritual, who play havoc with our perceptions and our lives. Lyrical, haunting, and compelling, The Icarus Girl is a story of twins and ghosts, of a little girl growing up between cultures and colors. It heralds the arrival of a remarkable new talent..
