Clifford algebra for dual quaternions has emerged recently as an alternative to standard matrix algebra as a computational framework for computer graphics. This book presents dual quaternions and their associated Clifford algebras in a new light, accessible to and geared toward the computer graphics community.Collecting all the associated formulas and theorems in one place, this book provides an extensive and rigorous treatment of dual quaternions, as well as showing how two models of Clifford algebra emerge naturally from the theory of dual quaternions. Each section comes complete with a set of exercises to help readers sharpen and practice their understanding.This book is accessible to anyone with a basic knowledge of quaternion algebra and is of particular use to forward-thinking members of the computer graphics community.

QUESTIONING CIRCUMCISION: A JEWISH PERSPECTIVE is the first critical examination of the growing controversy of male infant circumcision with special attention to contemporary concerns of the Jewish community. Endorsed by five rabbis among others, this extraordinary book examines the origins, assumed benefits, risks, and unrecognized consequences of the Jewish practice with thorough documentation and moving personal experiences. Consider these facts: Circumcision is not universal among Jews. Jewish press articles have questioned circumcision. A male child born of a Jewish mother is a Jew, whether he is circumcised or not. Jewish circumcision has never had anything to do with health concerns. Circumcision conflicts with significant Jewish laws and values. An Israeli organization publicly opposes circumcision. "Dr. Goldman has written a thoughtful, provocative book on a difficult subject. He challenges us to reexamine long-held assumptions and to reconsider the practice of milah (ritual circumcision) in light of contemporary evidence. By giving us an insightful and carefully documented exploration of a controversial perspective, Dr. Goldman helps to foster a healthy and valuable dialogue within the Jewish community." -Rabbi Jonathan Kraus, Beth El Temple Center "If you are a liberal Jew, whether you see circumcision as the sanctification of the covenant, as a ceremony marking you as a Jew, or otherwise, this book stimulates deeper reflection about the practice. As an aware, concerned, and introspective people, Jews must examine whether our rites are right. We must determine if our ceremonies, traditions, and practices reflect our innermost beliefs. Asking ourselves and each other the question 'Why?' is one of the most sacred tasks to which a modern Jew can dedicate himself or herself." -Rabbi Donald Pollock, pastoral psychotherapist, writer, and lecturer Ronald Goldman, Ph.D., a psychological researcher, educator, and writer, is the executive director of the Circumcision Resource Center in Boston, a nonprofit educational organization. He is internationally known for his work on circumcision, gives lectures and seminars on the subject, and provides consultation to expectant parents and circumcised men. As the author of Circumcision: The Hidden Trauma, Dr. Goldman has been a featured guest on local and national radio and television shows and has been published in medical journals, newspapers, parenting publications, and Jewish periodicals.

CIRCUMCISION: THE HIDDEN TRAUMA is the first intensive exploration of the unrecognized psychological and social aspects of this increasingly controversial American cultural practice. The book has been endorsed by dozens of professionals in psychology, psychiatry, child development, pediatrics, obstetrics, childbirth education, sociology, and anthropology, including Ashley Montagu, Christiane Northrup, Warren Farrell, Sheila Kitzinger, Sam Keen, and Penelope Leach. Without much knowledge, the American public generally assumes that our cultural practice of circumcision is a trivial and benign procedure. Plain facts and research results conflict with these beliefs and raise serious questions. Dr. Goldman's application of psychological and social research coherently explains both the tenacity of the practice and the contradictory information and beliefs about it. After a review of the surprising abilities of infants and their responses to circumcision pain, the long-term psychological effects of circumcision are examined from the perspectives of both traditional and innovative psychological theories. We learn that circumcision has potential effects not only on men and sexuality, but also on mother-child relationships, male-female relationships, and societal traits and problems. The text is supported with clinical reports, interviews, surveys, and thorough documentation. CIRCUMCISION: THE HIDDEN TRAUMA identifies an overlooked source of early pain and points us in the direction of both healing and preventing this pain. It is of particular interest to men who seek to explore their sexuality and deepen self-awareness; women who want to understand men better; parents and children's advocates; childbirth educators and allied workers; and mental health, medical, and academic professionals. The book has wide appeal because, more generally, it is about trusting our instincts, questioning some of our cultural values and assumptions, and reflecting on who we are and who we can be as individuals and as a society.
