This book is an introductory real analysis textbook, presented through the lens of history. That is, it proposes that an effective way to motivate the highly non-intuitve definitions and theorems encountered in an introductory, college level Real Analysis course is via one of the stories (there are many) of the historical development of the subject, from its intuitive beginnings to modern rigor. The definitions and techniques are motivated by the actual difficulties encountered by the intuitive approach and are presented in their historical context.

A little girl and her family have just moved across the country by train. Their new neighborhood in the city of Toronto is very different from their home in the Saskatchewan bush, and at first everything about “there” seems better than “here.” The little girl’s dad has just finished building a dam across the Saskatchewan River, and his new project is to build a highway through Toronto. In Saskatchewan, he would come home for lunch every day, but now he doesn’t come until supper. The family used to love to look at the stars, and the northern lights dancing in the night sky. But in the city, all they can see is the glare from the streetlights. All the kids used to run and play together, but now older brother Doug has his own friends. Then one day there is a knock on the door. It is Anne, who lives kitty-corner and is also eight, going on nine, and suddenly living in Toronto takes on a whole new light. Laurel Croza and Matt James have beautifully captured the voice and intense feelings of a young child who, in the midst of upheaval, finds hope in her new surroundings.

Her street name is Maybe She lives with a tribe of homeless teens -- runaways and throwaways, kids who have no place to go other than the cold city streets, and no family except for one another. Abused, abandoned, and forgotten, they struggle against the cold, hunger, and constant danger. With the frigid winds of January comes a new girl: Tears, a twelve-year-old whose mother doesn't believe her stepfather abuses her. As the other kids start to disappear -- victims of violence, addiction, and exposure -- Maybe tries to help Tears get off the streets...if it's not already too late. Todd Strasser, author of the powerful and disturbing Give a Boy a Gun, again focuses on an important social issue as he tells a thought-provoking, heart-wrenching story of young lives lost to the streets, and of a society that has forgotten how to care.

For over two decades Wesley Salmon has helped to shape the course of debate in philosophy of science. He is a major contributor to the philosophical discussion of problems associated with causality and the author of two influential books on scientific explanation. This long-awaited volume collects twenty- six of Salmon's essays, including seven that have never before been published and others difficult to find. Part I comprises five introductory essays that presuppose no formal training in philosophy of science and form a background for subsequent essays. Parts II and III contain Salmon's seminal work on scientific explanation and causality. Part IV offers survey articles that feature advanced material but remain accessible to those outside philosophy of science. Essays in Part V address specific issues in particular scientific disciplines, namely, archaeology and anthropology, astrophysics and cosmology, and physics. Clear, compelling, and essential, this volume offers a superb introduction to philosophy of science for nonspecialists and belongs on the bookshelf of all who carry out work in this exciting field. Wesley Salmon is renowned for his seminal contributions to the philosophy of science. He has powerfully and permanently shaped discussion of such issues as lawlike and probabilistic explanation and the interrelation of explanatory notions to causal notions. This unique volume brings together twenty-six of his essays on subjects related to causality and explanation, written over the period 1971-1995. Six of the essays have never been published before and many others have only appeared in obscure venues. The volume includes a section of accessible introductory pieces, as well as more advanced and technical pieces, and will make essential work in the philosophy of science readily available to both scholars and students.

Let's Go! takes readers on an amazing journey across our continent and through time to discover all the ways we've used to get from one place to another. From the very first "travelers" who came to this cold land across the Bering Land Bridge and through to future space travel, the story of transportation through the ages is the story of peoples' imagination, ingenuity, and resourcefulness. Readers take part in a journey across land, sea, and sky to see the First Peoples trailing travois and wearing snowshoes; traders and trappers crossing cold, fresh waters; and settlers in wooden ships, and horses pulling barges. Along the way, the pages offer a fascinating snapshot of life at different points in our history. As steamships, railways, streetcars, bicycles, cars, and airplanes come along, we see the world become a busier and busier place. And yet we're reminded that we still use the same ways to get around that were used in ancient times. A final spread of amazing "Did You Know" facts rounds out the book with more fascinating information on the time periods and modes of transportation covered in the book.

A famous writer exiled from Albania and Greece. A Somali nomad-turned-multinational banker. An Asian-born virtuoso violinist with perfect pitch, and many more . . . In this eye-opening collection of immigrant trials, triumphs, and contributions, leading immigration lawyer Susan Cohen invites you to walk with her clients as they share their incredible journeys coming to America while overcoming unimaginable dangers and often heartbreaking obstacles abroad. Cohen masterfully uplifts marginalized voices, laying bare the remarkable realities of staggering hardships and inspiring resilience. Sprinkled with amusing anecdotes, tense junctures, and heartwarming segments, you will sit front and center at the courtroom learning about US immigration policies and systems—which often become an immigrant’s greatest hurdle—while also discovering the ways unscrupulous American citizens take advantage of those not born in the States. As you ride the ups and downs and follow the zig-zagging twists and turns of their travails, you will discover the many ways immigrants from all over the world give back to their local communities and enrich the fabric of the nation. Finding yourself enmeshed in their stories, you will gain insight, grow in empathy, and come to understand what it truly takes to become an American citizen.

A Wired Most Fascinating Book of the Year “An important book that reminds us that navigation remains one of our most underappreciated arts.” —Tristan Gooley, author of The Lost Art of Reading Nature’s Signs “If you want to understand what rats can teach us about better-planned cities, why walking into a different room can help you find your car keys, or how your brain’s grid, border, and speed cells combine to give us a sense of direction, this book has all the answers.” —The Scotsman How is it that some of us can walk unfamiliar streets without losing our way, while the rest of us struggle even with a GPS? Navigating in uncharted territory is a remarkable feat if you stop to think about it. In this beguiling mix of science and storytelling, Michael Bond explores how we do it: how our brains make the “cognitive maps” that keep us orientated and how that anchors our sense of wellbeing. Children are instinctive explorers, developing a spatial understanding as they roam. And yet today few of us make use of the wayfinding skills that we inherited from our nomadic ancestors. Bond tells stories of the lost and found—sailors, orienteering champions, early aviators—and explores why being lost can be such a devastating experience. He considers how our understanding of the world around us affects our psychology and helps us see how our reliance on technology may be changing who we are. “Bond concludes that, by setting aside our GPS devices, by redesigning parts of our cities and play areas, and sometimes just by letting ourselves get lost, we can indeed revivify our ability to find our way, to the benefit of our inner world no less than the outer one.” —Science “A thoughtful argument about how our ability to find our way is integral to our nature.” —Sunday Times
