'Jacques's voice sings out loud and clear – wistful, drily humorous, stiletto-sharp.' – The Observer Variations is the debut short story collection from one of Britain's most compelling voices, Juliet Jacques. Using fiction inspired by found material and real-life events, Variations explores the history of transgender Britain with lyrical, acerbic wit. Variations travels from Oscar Wilde's London to austerity-era Belfast via inter-war Cardiff, a drag bar in Liverpool just after the decriminalisation of homosexuality, Manchester's protests against Clause 28, and Brighton in the 2000s. Through diary entries of an illicit love affair, an oral history of a contemporary political collective; a 1920s academic paper to a 1990s film script; a 1950s memoir to a series of 2014 blog posts, Jacques rewrites and reinvigorates a history so often relegated to stale police records and sensationalist news headlines. Innovative and fresh, Variations is a bold and beautiful book of stories unheard; until now. 'Everything about this book—from the conception, to the language, to the execution—makes me wish I'd been the one to write it. Except I couldn't have. Juliet Jacques is a complete original and this book is the proof.' – Torrey Peters

Darwin's theory of evolution by natural selection was based on the observation that there is variation between individuals within the same species. This fundamental observation is a central concept in evolutionary biology. However, variation is only rarely treated directly. It has remained peripheral to the study of mechanisms of evolutionary change. The explosion of knowledge in genetics, developmental biology, and the ongoing synthesis of evolutionary and developmental biology has made it possible for us to study the factors that limit, enhance, or structure variation at the level of an animals' physical appearance and behavior. Knowledge of the significance of variability is crucial to this emerging synthesis. Variation situates the role of variability within this broad framework, bringing variation back to the center of the evolutionary stage. - Provides an overview of current thinking on variation in evolutionary biology, functional morphology, and evolutionary developmental biology - Written by a team of leading scholars specializing on the study of variation - Reviews of statistical analysis of variation by leading authorities - Key chapters focus on the role of the study of phenotypic variation for evolutionary, developmental, and post-genomic biology

Fiction. NECROPHILIA VARIATIONS is a literary monograph on the erotic attraction to corpses and death. It consists of a series of texts that, like musical phrases, take up the theme and advance it by means of repetition, contrast, and variation.Written in a style that ranges from the lugubrious to the ludicrous--from purple prose to black humor--NECROPHILIA VARIATIONS uses literary means to probe the psychopathology of sexual perversion. Eros, the book asks, is naturally drawn to beauty, and yet nothing would seem to be less inherently beautiful than a cadaver. How is it that a necrophile ends up confusing the two, discovering beauty in what most people would find repugnant? How does he come to desire that which would seem to be intrinsically undesirable? If you have ever contemplated the curious points of contact between eros and thanatos, then Necrophilia Variations will be sure to delight you with its depictions of death, desire, and deviance.

A constellation of short stories illustrate the intersecting lives of women on various peripheries of society in and around Bogotá, Colombia. In six subtly connected stories, Variations on the Body explores the obsessions, desires, and idiosyncrasies of women and girls from different strata of Colombian society. A former FARC guerilla fighter adjusts to urban life and faces the new violence of an editor co-opting her experiences. A woman adrift in the city she left as a child looks for someone to care for, even if it has to be by force, while another documents a flea infestation with a catalog of the marks on her flesh. A little girl copes with her anxiety about the adult world by exacting revenge on her nanny, who she thinks belongs to her. Combining humor, heartbreak, and unexpected violence, Ospina constructs a keen reflection on the body as a simultaneous vehicle of connection and alienation in vibrant, gleaming prose.

Fresh, lively text serves as a modern introduction to the subject, with applications to the mechanics of systems with a finite number of degrees of freedom. Ideal for math and physics students.

From the graceful flutter of Princess Florine at Sleeping Beauty's wedding to the playful jetées in the first act of Giselle, the variation - or short solo work - is one of the key elements of classical ballet. Arguing that true artistry requires in-depth knowledge, author Nina Danilova has worked with students for many years to focus on performing individual variations with the greatest extent of technical proficiency and artistic sensitivity. Eight Female Classical Ballet Variations lays out eight variations in the ballerina's repertoire. Each chapter is divided into five sections: a piano reduction of the score; a contextual note covering the history of the ballet, the plot, and memorable dancers who have performed the role; and instructions for dancing the variation itself, illustrated step by step. Accompanied by a comprehensive companion website, Eight Female Classical Ballet Variations pairs Danilova's method of teaching students with her decades of pedagogical experience.

Provides a thorough understanding of calculus of variations and prepares readers for the study of modern optimal control theory. Selected variational problems and over 400 exercises. Bibliography. 1969 edition.

National Bestseller National Book Critics Circle Award Nominee From the Pulitzer Prize–winning author of The Overstory and the forthcoming Bewilderment, a magnificent double love story of two young couples separated by a distance of twenty-five years. “The most lavishly ambitious American novel since Gravity’s Rainbow . . . An outright marvel.” —Washington Post Stuart Ressler, a brilliant young molecular biologist, sets out in 1957 to crack the genetic code. His efforts are sidetracked by other, more intractable codes—social, moral, musical, spiritual—and he falls in love with a member of his research team. Years later, another young man and woman team up to investigate a different scientific mystery: Why did the eminently promising Ressler suddenly disappear from the world of science? Strand by strand, these two love stories twist about each other in a double helix of desire. The critically acclaimed third novel from Pulitzer Prize–winning author Richard Powers, The Gold Bug Variations is an intellectual tour-de-force that probes the meaning of love, science, music, and art.

From André Aciman, the author of Call Me by Your Name (now a major motion picture and the winner of the OscarTM for Best Adapted Screenplay) comes “a sensory masterclass, absorbing, intelligent, unforgettable” (Times Literary Supplement). André Aciman, hailed as a writer of “fiction at its most supremely interesting” (The New York Review of Books), has written a novel that charts the life of a man named Paul, whose loves remain as consuming and as covetous throughout his adulthood as they were in his adolescence. Whether the setting is southern Italy, where as a boy he has a crush on his parents’ cabinetmaker, or a snowbound campus in New England, where his enduring passion for a girl he’ll meet again and again over the years is punctuated by anonymous encounters with men; whether he’s on a tennis court in Central Park, or on a New York sidewalk in early spring, his attachments are ungraspable, transient, and forever underwritten by raw desire—not for just one person’s body but, inevitably, for someone else’s as well. In Enigma Variations, Aciman maps the most inscrutable corners of passion, proving to be an unsparing reader of the human psyche and a master stylist. With language at once lyrical, bare-knuckled, and unabashedly candid, he casts a sensuous, shimmering light over each facet of desire to probe how we ache, want, and waver, and ultimately how we sometimes falter and let go of those who may want to offer only what we crave from them. Ahead of every step Paul takes, his hopes, denials, fears, and regrets are always ready to lay their traps. Yet the dream of love lingers. We may not always know what we want. We may remain enigmas to ourselves and to others. But sooner or later we discover who we’ve always known we were.
