To Infinity and Beyond: A Cultural History of the Infinite
To Infinity and Beyond
A Cultural History of the Infinite
Paperback      ISBN: 0691025118

Eli Maor examines the role of infinity in mathematics and geometry and its cultural impact on the arts and sciences. He evokes the profound intellectual impact the infinite has exercised on the human mind--from the "horror infiniti" of the Greeks to the works of M. C. Escher; from the ornamental designs of the Moslems, to the sage Giordano Bruno, whose belief in an infinite universe led to his death at the hands of the Inquisition. But above all, the book describes the mathematician's fascination with infinity--a fascination mingled with puzzlement. "Maor explores the idea of infinity in mathematics and in art and argues that this is the point of contact between the two, best exemplified by the work of the Dutch artist M. C. Escher, six of whose works are shown here in beautiful color plates."--Los Angeles Times " Eli Maor's] enthusiasm for the topic carries the reader through a rich panorama."--Choice "Fascinating and enjoyable.... places the ideas of infinity in a cultural context and shows how they have been espoused and molded by mathematics."--Science

Kiss My Math: Showing Pre-Algebra Who's Boss
Kiss My Math
Showing Pre-Algebra Who's Boss
Paperback      ISBN: 0452295408
The New York Times bestselling math workbook from actress and math genius Danica McKellar that teaches seventh to ninth grade girls how to conquer pre-algebra

Stepping up not only the math but the sass and style, McKellar helps math-phobic teenagers moving up into high school chill out and finally "get" negative numbers, variables, absolute values, exponents, and more. As she did so effectively in Math Doesn't Suck, McKellar uses personality quizzes, reader polls, real-life testimonials, and stories from her own life--in addition to clear instruction, helpful tips, and practice problems--revealing why pre-algebra is easier, more relevant, and more glamorous than girls think.
Algebra Survival Guide: A Conversational Handbook for the Thoroughly Befuddled
Algebra Survival Guide
A Conversational Handbook for the Thoroughly Befuddled
Paperback      ISBN: 0965911381

If there's one question that many parents would rather not hear when Sophia or Aiden gets home from school, it's, "Mom, can you help me with my algebra homework?"

And nowadays that question gets asked by younger and younger children because algebraic thinking has been inserted into the math curriculum as early as 5th grade, sometimes even in 4th grade

So what helps parents recall algebra and also helps students learn it in a friendly way? The Algebra Survival Guide, now updated in its Second Edition.

Following on the success of the award-winning First Edition book and written by teacher/tutor Josh Rappaport, the Second Edition Guide offers time-tested advice for understanding the key areas of this gateway math subject.

The new Algebra Survival Guide features a unique Q&A format so students hear their own questions echoed in the text. The book's answers, written in the voice of a friendly tutor, provide conversational responses, along with step-by-step instructions in English right next to the math steps.

Each page is a one-page mini-lesson so students can focus without feeling overwhelmed. Following each lesson is a short set of practice problems, offering students instant feedback. At the end of each section, chapter tests provide comprehensive checks on understanding.

Since word problems are often the highest "hurdle" of algebra, the Second Edition contains a new 62-page chapter on advanced word problems. This chapter provides detailed strategies for setting up and solving word problems on such dastardly areas as rate, time and distance, work performed, mixture formulas, and even those crazy problems about Joe being three years older than four times Jane's age 10 years in the future.

In its twelve content chapters the 352-page Second Edition covers all key areas of PreAlgebra and Algebra 1: Algebraic Properties, Sets of Numbers, Positive and Negative Numbers, Order of Operations, Absolute Value, Exponents, Radicals, Factoring, Cancelling, Solving Equations, the Coordinate Plane, and Word Problems.

As a major bonus, the Guide buzzes with lively illustrations by award-winning artist Sally Blakemore. Ms. Blakemore's cartoons not only provide comic relief, they also offer a visual way to grasp algebra's challenging abstractions. (Example: to illustrate the Reflexive Property of x = x, a cartoon shows a sad 'x' gazing at itself in the mirror while suffering a 'bad hair day.') With all of these features, the Second Edition Algebra Survival Guide appeals equally to homeschoolers, students, parents, teachers, tutors and adult students striving to recall the math they learned a decade or so ago.

The Second Edition aligns with the Common Core State Standards for Math, so it's up-to-date for today's teachers.

Loaded with thorough explanations, practice problems and answers, the new Algebra Survival Guide gives anyone and everyone the needed boost for learning or teaching the timeless and critical subject of algebra.

Gaming: Essays on Algorithmic Culture
Essays on Algorithmic Culture
Paperback      ISBN: 0816648514

Video games have been a central feature of the cultural landscape for over twenty years and now rival older media like movies, television, and music in popularity and cultural influence. Yet there have been relatively few attempts to understand the video game as an independent medium. Most such efforts focus on the earliest generation of text-based adventures (Zork, for example) and have little to say about such visually and conceptually sophisticated games as Final Fantasy X, Shenmue, Grand Theft Auto, Halo, and The Sims, in which players inhabit elaborately detailed worlds and manipulate digital avatars with a vast--and in some cases, almost unlimited--array of actions and choices.

In Gaming, Alexander Galloway instead considers the video game as a distinct cultural form that demands a new and unique interpretive framework. Drawing on a wide range of disciplines, particularly critical theory and media studies, he analyzes video games as something to be played rather than as texts to be read, and traces in five concise chapters how the "algorithmic culture" created by video games intersects with theories of visuality, realism, allegory, and the avant-garde. If photographs are images and films are moving images, then, Galloway asserts, video games are best defined as actions.

Using examples from more than fifty video games, Galloway constructs a classification system of action in video games, incorporating standard elements of gameplay as well as software crashes, network lags, and the use of cheats and game hacks. In subsequent chapters, he explores the overlap between the conventions of film and video games, the political and cultural implications of gaming practices, the visual environment of video games, and the status of games as an emerging cultural form.

Together, these essays offer a new conception of gaming and, more broadly, of electronic culture as a whole, one that celebrates and does not lament the qualities of the digital age.

Alexander R. Galloway is assistant professor of culture and communication at New York University and author of Protocol: How Control Exists after Decentralization.
