    But after her father suddenly passed away, leaving none of his fortune behind, Eden forced herself to grow up and become practical. Step one was accepting a job at Camp Liberty, a summer camp for girls. Even a year after her world fell apart, Eden is still grappling with her new responsibilities—especially keeping the campers out of their neighbor’s apple orchard. Chase Elliot is overbearing, and very strict about trespassers. Eden is more than happy to stay out of his way, but soon she finds Chase bumping into her every chance he gets. Eden’s past relationship proved to be a sham, so she constantly brushes Chase off, but sometimes temptation is too hard to resist!The Best MistakeEx-model Zoe Fleming is now a hardworking single mom—and she wouldn’t have it any other way. She does need a tenant to help with the household expenses, and when she enlists for one, comfirmed bachelor J. Cooper McKinnon signs the lease. Handsome as he is, Zoe is too busy for romance, and even if she wasn’t, Coop is not the type of man she had in mind: a sports reporter who admits he doesn’t understand kids. Coop wasn’t planning on settling down anyway, and he certainly didn’t sign up to be a father, but the more time he spends getting to know Zoe and her son, Keenan, the more he can picture their future as a family. If only he can convince Zoe he’s finally ready to commit…

    The New Society in which Filipinos live today may be described as their emancipation from an old society whose hallmark was injustice, the supreme injustice in which equality of opportunity was withheld from them by an oligarchy that appropriated for itself all power and bounty. The New Society is in fact a revolution of the poor. By means of it, Filipinos today are attempting, through disciplined vision, to make the rewards of their labors and the fruits of their resources available to all. By means of it, they are walking out of a stupor filled with Walter Mitty fantasies, the opium of the oppressed and underprivileged. To share together in real life is the heart of democracy. Accordingly, the New Society is democratizing the wealth of the nation, striving to move democracy from cloud to hovel.(from its Preface)

    A masterpiece of technical exposition, it was the basic textbook of astronomy for more than a thousand years, and still is the main source for our knowledge of ancient astronomy. This translation, based on the standard Greek text of Heiberg, makes the work accessible to English readers in an intelligible and reliable form. It contains numerous corrections derived from medieval Arabic translations and extensive footnotes that take account of the great progress in understanding the work made in this century, due to the discovery of Babylonian records and other researches. It is designed to stand by itself as an interpretation of the original, but it will also be useful as an aid to reading the Greek text.

    These topics lie at the heart of many exciting areas of contemporary science and engineering - communication, signal processing, data mining, machine learning, pattern recognition, computational neuroscience, bioinformatics, and cryptography. This textbook introduces theory in tandem with applications. Information theory is taught alongside practical communication systems, such as arithmetic coding for data compression and sparse-graph codes for error-correction. A toolbox of inference techniques, including message-passing algorithms, Monte Carlo methods, and variational approximations, are developed alongside applications of these tools to clustering, convolutional codes, independent component analysis, and neural networks. The final part of the book describes the state of the art in error-correcting codes, including low-density parity-check codes, turbo codes, and digital fountain codes -- the twenty-first century standards for satellite communications, disk drives, and data broadcast. Richly illustrated, filled with worked examples and over 400 exercises, some with detailed solutions, David MacKay's groundbreaking book is ideal for self-learning and for undergraduate or graduate courses. Interludes on crosswords, evolution, and sex provide entertainment along the way. In sum, this is a textbook on information, communication, and coding for a new generation of students, and an unparalleled entry point into these subjects for professionals in areas as diverse as computational biology, financial engineering, and machine learning.

    Book is unique in its emphasis on the frequency approach and its use in the solution of problems. Contents include: Fundamentals and Algorithms; Polynomial Approximation — Classical Theory; Fourier Approximation — Modern Theory; and Exponential Approximation.

    In his own words: "Dare to be naive... It is one of our most exciting discoveries that local discovery leads to a complex of further discoveries."

    Remarkable for his range of thought and his mastery of treatment, Archimedes addressed such topics as the famous problems of the ratio of the areas of a cylinder and an inscribed sphere; the measurement of a circle; the properties of conoids, spheroids, and spirals; and the quadrature of the parabola. This edition offers an informative introduction with many valuable insights into the ancient mathematician's life and thought as well as the views of his contemporaries. Modern mathematicians, physicists, science historians, and logicians will find this volume a source of timeless fascination.

    In this volume, Karen Barad, theoretical physicist and feminist theorist, elaborates her theory of agential realism. Offering an account of the world as a whole rather than as composed of separate natural and social realms, agential realism is at once a new epistemology, ontology, and ethics. The starting point for Barad’s analysis is the philosophical framework of quantum physicist Niels Bohr. Barad extends and partially revises Bohr’s philosophical views in light of current scholarship in physics, science studies, and the philosophy of science as well as feminist, poststructuralist, and other critical social theories. In the process, she significantly reworks understandings of space, time, matter, causality, agency, subjectivity, and objectivity.In an agential realist account, the world is made of entanglements of “social” and “natural” agencies, where the distinction between the two emerges out of specific intra-actions. Intra-activity is an inexhaustible dynamism that configures and reconfigures relations of space-time-matter. In explaining intra-activity, Barad reveals questions about how nature and culture interact and change over time to be fundamentally misguided. And she reframes understanding of the nature of scientific and political practices and their “interrelationship.” Thus she pays particular attention to the responsible practice of science, and she emphasizes changes in the understanding of political practices, critically reworking Judith Butler’s influential theory of performativity. Finally, Barad uses agential realism to produce a new interpretation of quantum physics, demonstrating that agential realism is more than a means of reflecting on science; it can be used to actually do science.

    A female officer who is attacked in the line of duty must protect her own husband from his worst impulses in this short story, first published in The Blue Religion (Michael Connelly, ed.) and recognized as one of 2009's Best American Mystery Stories (Jeffery Deaver, ed.).

    Devoted to her husband, a pediatric oncologist at a major cancer hospital, their young son Henry, and the patients she sees in her therapy practice, her days are full of familiar things: she lives in the very New York apartment in which she was raised, and sends Henry to the school she herself once attended. Dismayed by the ways in which women delude themselves, Grace is also the author of a book You Should Have Known, in which she cautions women to really hear what men are trying to tell them. But weeks before the book is published a chasm opens in her own life: a violent death, a missing husband, and, in the place of a man Grace thought she knew, only an ongoing chain of terrible revelations. Left behind in the wake of a spreading and very public disaster, and horrified by the ways in which she has failed to heed her own advice, Grace must dismantle one life and create another for her child and herself. For readers of the best women's fiction. This is a free preview, not the full book.
