This graduate/advanced undergraduate textbook contains a systematic and elementary treatment of finite groups generated by reflections. The approach is based on fundamental geometric considerations in Coxeter complexes, and emphasizes the intuitive geometric aspects of the theory of reflection groups. Key features include: many important concepts in the proofs are illustrated in simple drawings, which give easy access to the theory; a large number of exercises at various levels of difficulty; some Euclidean geometry is included along with the theory of convex polyhedra; no prerequisites are necessary beyond the basic concepts of linear algebra and group theory; and a good index and bibliography The exposition is directed at advanced undergraduates and first-year graduate students.

Discover the power of mirror meditation to help you awaken self-compassion, increase self-awareness, and gain the confidence needed to thrive. Seeing ourselves clearly isn’t always easy—especially in the age of social media. Technology has eroded our capacity for authentic self-reflection. As a result, we feel more anxious and depressed, have shorter attention spans, and have become more estranged from ourselves and each other. We’ve also become more critical of our physical appearance, and this self-criticism can damage our confidence and stand in the way of our happiness. In order to heal, we must come face to face with our true selves—not the images of ourselves that we alter and post online. If you're ready for self-reflection that has nothing to do with selfies, this book will reveal the way. Based in cutting-edge neuroscience, Mirror Meditation offers mindful practices for increasing your self-awareness, managing stress and emotions, developing self-compassion, and increasing your confidence and personal presence. Using the three principles of mindfulness meditation—attention to the present moment, open awareness, and kind intention toward oneself—you’ll realize just how much your self-criticisms are affecting you. Then you’ll have a choice—and a practice—to treat yourself with more self-acceptance. Self-awareness can help you break free from both your inner critic and the external world that stokes the fears and anxieties that we are never good enough, never have enough, and are never safe enough. The simple self-mirroring technique in this unique guide isn’t grounded in technology—just a commitment to be present with yourself.

Of all human inventions, the mirror is perhaps the one most closely connected to our own consciousness. As our first technology for contemplation of the self, the mirror is arguably as important an invention as the wheel. Mirror Mirror is the fascinating story of the mirror's invention, refinement, and use in an astonishing range of human activities -- from the fantastic mirrored rooms that wealthy Romans created for their orgies to the mirror's key role in the use and understanding of light. Pendergrast spins tales of the 2,500year mystery of whether Archimedes and his "burning mirror" really set faraway Roman ships on fire; the medieval Venetian glassmakers, who perfected the technique of making large, flat mirrors from clear glass and for whom any attempt to leave their cloistered island was punishable by death; Isaac Newton, whose experiments with sunlight on mirrors once left him blinded for three days; the artist David Hockney, who holds controversial ideas about Renaissance artists and their use of optical devices; and George Ellery Hale, the manic-depressive astronomer and telescope enthusiast who inspired (and gave his name to) the twentieth century's largest ground-based telescope. Like mirrors themselves, Mirror Mirror is a book of endless wonder and fascination.

Her Silence is BROKEN. Her voice is now heard. Echoing loud, vibrant and FREE. A decade's long journey will now be told. from successfully single to married with five children in one year. Chronicling homelessness, marital affairs, grief, loss, divorce, and joy. All while learning to listen to that still small voice. Crying God where are you. Learning to find him in the murkiest of waters. These are her personal reflections.

A thrilling gothic horror novel about biracial twin sisters separated at birth, perfect for fans of Lovecraft Country and The Vanishing Half As infants, twin sisters Charlie Yates and Magnolia Heathwood were secretly separated after the brutal lynching of their parents, who died for loving across the color line. Now, at the dawn of the Civil Rights Movement, Charlie is a young Black organizer in Harlem, while white-passing Magnolia is the heiress to a cotton plantation in rural Georgia. Magnolia knows nothing of her racial heritage, but secrets are hard to keep in a town haunted by the ghosts of its slave-holding past. When Magnolia finally learns the truth, her reflection mysteriously disappears from mirrors—the sign of a terrible curse. Meanwhile, in Harlem, Charlie's beloved grandmother falls ill. Her final wish is to be buried back home in Georgia—and, unbeknownst to Charlie, to see her long-lost granddaughter, Magnolia Heathwood, one last time. So Charlie travels into the Deep South, confronting the land of her worst nightmares—and Jim Crow segregation. The sisters reunite as teenagers in the deeply haunted town of Eureka, Georgia, where ghosts linger centuries after their time and dangers lurk behind every mirror. They couldn’t be more different, but they will need each other to put the hauntings of the past to rest, to break the mirrors’ deadly curse—and to discover the meaning of sisterhood in a racially divided land.

She begins with an intriguing tour through the history of the mirror, from its origins in prehistory right up to the present. With the help of 200 spectacular photographs, she demonstrates the many remarkable ways in which mirror has been used over the past three centuries to transform spaces of every size and shape. Using dozens of examples, ranging from the Palace at Versailles to a modern shoe store in New York City, she describes techniques developed by architects and designers to alter perspectives and change the way people respond to both private and public spaces. Ms. Heyne explores the use of mirror in a variety of settings - from bedrooms, living rooms, exercise rooms, and nurseries, to restaurants, lobbies, clothing stores, and hospitals. She offers valuable technical advice on the uses and misuses of mirror in a wide variety of settings and summarizes what is known about the psychological impact of mirror in each setting.
