Apart from an introductory chapter giving a brief summary of Newtonian and Lagrangian mechanics, this book consists entirely of questions and solutions on topics in classical mechanics that will be encountered in undergraduate and graduate courses. These include one-, two-, and three-dimensional motion; linear and non-linear oscillations; energy, potentials, momentum, and angular momentum; spherically symmetric potentials; multi-particle systems; rigid bodies; translation and rotation of the reference frame; and the relativity principle and some of its consequences. The solutions are followed by a set of comments intended to stimulate inductive reasoning and provide additional information of interest. Both analytical and numerical (computer) techniques are used to obtain and analyze solutions. The computer calculations use Mathematica® (version 7), and the relevant code is given in the text. It includes use of the interactive Manipulate function which enables one to observe simulated motion on a computer screen, and to study the effects of changing parameters.

The book will be useful to students and lecturers in undergraduate and graduate courses on classical mechanics, and students and lecturers in courses in computational physics.

`The writing is succinct and clear and the comments often bring out the relevance of the problem to a phenomenon of current interest as well as points of historical importance. The problems are varied and well chosen.'--- A.D. Buckingham, Cambridge University

This book addresses production and inventory management problems where products can be replaced by specified substitutes. Depending on the considered application, substitutions can potentially improve the service level, reduce required safety stocks and total setup costs and times, utilize cost variations of input products, and reduce the amount of wastage. The main focus is the development of graphical modeling approaches for substitution options and of production planning models based on these approaches using mathematical programming. In addition to single-level dynamic lot-sizing models with substitutions, models for multi-level production systems with flexible bills-of-materials and recipes are devised. Also, a simulation-based optimization approach for a multi-location inventory system with substitutions is developed.

If we could turn back the clock psychologically, could we also turn it back physically? For more than thirty years, award-winning social psychologist Ellen Langer has studied this provocative question, and now, in Counterclockwise, she presents a conclusive answer: Opening our minds to what’s possible, instead of presuming impossibility, can lead to better health—at any age. Drawing on landmark work in the field and her own body of highly original experiments—including her “counterclockwise” study, in which elderly men lived for a week as though it was 1959 and showed dramatic improvements in their hearing, memory, dexterity, appetite, and general well-being—Langer shows that the magic of rejuvenation and ongoing good health lies in being aware of the ways we mindlessly react to social and cultural cues. Examining the intricate but often defeatist ways we define our physical health, Langer challenges the idea that the limits we assume and impose on ourselves are real. With only subtle shifts in our thinking, in our language, and in our expectations, she tells us, we can begin to change the ingrained behaviors that sap health, optimism, and vitality from our lives. Improved vision, weight loss, and increased longevity are just three of the results that Langer has demonstrated.Provocative and riveting, Counterclockwise offers a transformative and bold new paradigm: the psychology of possibility. A hopeful and groundbreaking work by an author who has changed how people all over the world think and feel, Counterclockwise is sure to join Mindfulness as a standard source on new-century science and healing.

If we could turn back the clock psychologically, could we also turn it back physically? For more than thirty years, award-winning social psychologist Ellen Langer has studied this provocative question, and now, in Counterclockwise, she presents the answer: Opening our minds to what's possible, instead of presuming impossibility, can lead to better health–at any age.

Drawing on landmark work in the field and her own body of colorful and highly original experiments–including the first detailed discussion of her “counterclockwise” study, in which elderly men lived for a week as though it was 1959 and showed dramatic improvements in their hearing, memory, dexterity, appetite, and general well-being–Langer shows that the magic of rejuvenation and ongoing good health lies in being aware of the ways we mindlessly react to social and cultural cues. Examining the hidden decisions and vocabulary that shape the medical world (“chronic” versus “acute,” “cure” versus “remission”), the powerful physical effects of placebos, and the intricate but often defeatist ways we define our physical health, Langer challenges the idea that the limits we assume and impose on ourselves are real. With only subtle shifts in our thinking, in our language, and in our expectations, she tells us, we can begin to change the ingrained behaviors that sap health, optimism, and vitality from our lives. Improved vision, younger appearance, weight loss, and increased longevity are just four of the results that Langer has demonstrated.

Immensely readable and riveting, Counterclockwise offers a transformative and bold new paradigm: the psychology of possibility. A hopeful and groundbreaking book by an author who has changed how people all over the world think and feel, Counterclockwise is sure to join Mindfulness as a standard source on new-century science and healing.

Ellen J. Langer, Harvard professor of psychology, determines that the mindless following of routine and other automatic behaviors lead to much error, pain and a predetermined course of life.

In this thought provoking audiobook, her research has been "translated" for the lay listener. With anecdotes and metaphors, Langer explains how the mindless--as opposed to the mindful--develop mindsets of categories, associations, habits of thought born of repetition in childhood and throughout schooling. To be mindful, she notes, stressing process over outcome, allows free rein to intuition and creativity, and opens us to new information and perspectives.

Langer discusses the negative impact of mindsets on business and social relations, showing special concern for the elderly, who often suffer from learned helplessness and lack of options.

Encouraging the application of mindfulness to health, the author affirms that placebos and alternative, mind-based therapies can help patients and addicts move from unhealthy to healthy contexts.

“All it takes to become an artist is to start doing art.”
–from On Becoming an Artist

On Becoming an Artist is loaded with good news. Backed by her landmark scientific work on mindfulness and artistic nature, bestselling author and Harvard psychologist Ellen J. Langer shows us that creativity is not a rare gift that only some special few are born with, but rather an integral part of everyone's makeup. All of us can express our creative impulses– authentically and uniquely–and, in the process, enrich our lives.

Why then do so many of us merely dream of someday painting, someday writing, someday making music? Why do we think the same old thoughts, harbor the same old prejudices, stay stuck in the same old mud? Who taught us to think “inside the box”?

No one is more qualified to answer these questions than Dr. Langer, who has explored their every facet for years. She describes dozens of fascinating experiments–her own and those of her colleagues–that are designed to study mindfulness and its relation to human creativity, and she shares the profound implications of the results–for our well-being, health, and happiness.

Langer reveals myriad insights, among them: We think we should already know what only firsthand experience can teach us. . . . In learning the ways that all roses are alike, we risk becoming blind to their differences. . . . If we are mindfully creative, the circumstances of the moment will tell us what to do. . . . Those of us who are less evaluatively inclined experience less guilt, less regret, less blame, and tend to like ourselves more. . . . Uncertainty gives us the freedom to discover meaning. . . . Finally, what we think we're sure of may not even exist.

With the skill of a gifted logician, Langer demonstrates exactly how we undervalue ourselves and undermine our creativity. By example, she persuades us to have faith in our creative works, not because someone else approves of them but because they're a true expression of ourselves. Her high-spirited, challenging book sparkles with wit and intelligence and inspires in us an infectious enthusiasm for our creations, our world, and ourselves. It can be of lifelong value to everyone who reads it.
