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

This textbook, based on courses taught at Harvard University, is an introduction to group theory and its application to physics. The physical applications are considered as the mathematical theory is developed so that the presentation is unusually cohesive and well-motivated. Many modern topics are dealt with, and there is much discussion of the group SU(n) and its representations. This is of great significance in elementary particle physics. Applications to solid state physics are also considered. This stimulating account will prove to be an essential resource for senior undergraduate students and their teachers.

From tribal religious rituals to the Playboy mansion, and from ancient Rome to Burning Man, Plays Well in Groups explores the phenomenon of group sex. Author Katherine Frank draws on surveys, ethnographic research, participant interviews, and more to provide explanations for both, participation in group sex and our complex reactions to it, from fascination to fear. This book looks at group sex across cultures—who has it, and why. Group sex is almost always taboo and often criminalized, and yet it persists across cultures throughout history. Plays Well in Groups looks at the symbolism of orgies, as well as contemporary manifestations of group sex in bathhouses and public sex venues, at BDSM and swinging parties, on Craigslist, and in political scandals, Tantra classes, reality television, and more. Frank explores the many reasons people participate in group sex, from arousal to spiritual transcendence, in this bold study of subversive sexuality.

Following the same successful approach as Dr. Burn's previous book on number theory, this text consists of a carefully constructed sequence of questions that will enable the reader, through participation, to study all the group theory covered by a conventional first university course. An introduction to vector spaces, leading to the study of linear groups, and an introduction to complex numbers, leading to the study of Möbius transformations and stereographic projection, are also included. Quaternions and their relationships to 3-dimensional isometries are covered, and the climax of the book is a study of the crystallographic groups, with a complete analysis of these groups in two dimensions.

This important, pioneering book collates our knowledge of large groups, both at a theoretical and practical level. Thirteen distinguished contributors offer experiences from a wide range of disciplines and settings. Roughly half the chapters are psychoanalytic in their orientation; other contributions derive from general psychiatry, sociology, anthropology and industrial psychology.The place of large-group therapy is still to be defined, but it is hoped that this book will contribute to the careful and detailed assessment that is necessary to fulfill its evaluation.

This first volume of clasic articles by the Glasgow University Media Group focuses on issues of news content, language and the role of visual images in news reporting. It also includes an introduction to the Group's work by John Eldridge.

Book clubs are everywhere these days. And women talk about the clubs they belong to with surprising emotion. But why are the clubs so important to them? And what do the women discuss when they meet? To answer questions like these, Elizabeth Long spent years observing and participating in women's book clubs and interviewing members from different discussion groups. Far from being an isolated activity, she finds reading for club members to be an active and social pursuit, a crucial way for women to reflect creatively on the meaning of their lives and their place in the social order.

This two-volume set LNAI 12748 and 12749 constitutes the refereed proceedings of the 22nd International Conference on Artificial Intelligence in Education, AIED 2021, held in Utrecht, The Netherlands, in June 2021.* The 40 full papers presented together with 76 short papers, 2 panels papers, 4 industry papers, 4 doctoral consortium, and 6 workshop papers were carefully reviewed and selected from 209 submissions. The conference provides opportunities for the cross-fertilization of approaches, techniques and ideas from the many fields that comprise AIED, including computer science, cognitive and learning sciences, education, game design, psychology, sociology, linguistics as well as many domain-specific areas. ​*The conference was held virtually due to the COVID-19 pandemic.

This book is based on a one-semester course for advanced undergraduates specializing in physical chemistry. I am aware that the mathematical training of most science majors is more heavily weighted towards analysis – typ- ally calculus and differential equations – than towards algebra. But it remains my conviction that the basic ideas and applications of group theory are not only vital, but not dif?cult to learn, even though a formal mathematical setting with emphasis on rigor and completeness is not the place where most chemists would feel most comfortable in learning them. The presentation here is short, and limited to those aspects of symmetry and group theory that are directly useful in interpreting molecular structure and spectroscopy. Nevertheless I hope that the reader will begin to sense some of the beauty of the subject. Symmetry is at the heart of our understanding of the physical laws of nature. If a reader is happy with what appears in this book, I must count this a success. But if the book motivates a reader to move deeper into the subject, I shall be grati?ed.
