The Book of Circles & Lines is part guide, part concept art, and part mental rabbit hole, designed to make you question the very foundations of how you think about the world. If you'll let it, this book will open you up to a whole new way of approaching life, help you break through mental blockers, and take you on a journey of self discovery that will change the way you think forever. Welcome to the maddeningly simple, yet infinitely deep black box that is The Book of Circles & Lines. *****************If you purchased a print copy, I will send you a free digital copy!

In this intimate, engaging book, John Demos offers an illuminating portrait of how colonial Americans, from the first settlers to the postrevolutionary generation, viewed their life experiences. He also offers an invaluable inside look into the craft of a master social historian as he unearths--in sometimes unexpected places--fragments of evidence that help us probe the interior lives of people from the faraway past. The earliest settlers lived in a traditional world of natural cycles that shaped their behavior: day and night; seasonal rhythms; the lunar cycle; the life cycle itself. Indeed, so basic were these elements that "almost no one felt a need to comment on them." Yet he finds cyclical patterns--in the seasonal foods they ate, in the spike in marriages following the autumn harvest. Witchcraft cases reveal the different emotional reactions to day versus night, as accidental mishaps in the light become fearful nighttime mysteries. During the transitional world of the American Revolution, people began to see their society in newer terms but seemed unable or unwilling to come to terms with that novelty. Americans became new, Demos points out, before they fully understood what it meant. Their cyclical frame of reference was coming unmoored, giving way to a linear world view in early nineteenth-century America that is neatly captured by Kentucky doctor Daniel Drake's description of the chronography of his life. In his meditation on these three worlds, Demos brilliantly demonstrates how large historical forces are reflected in individual lives. With the imaginative insights and personable touch that we have come to expect from this fine chronicler of the human condition, "Circles and Lines" is vintage John Demos.

Geometry: The Line and the Circle is an undergraduate text with a strong narrative that is written at the appropriate level of rigor for an upper-level survey or axiomatic course in geometry. Starting with Euclid's Elements, the book connects topics in Euclidean and non-Euclidean geometry in an intentional and meaningful way, with historical context. The line and the circle are the principal characters driving the narrative. In every geometry considered—which include spherical, hyperbolic, and taxicab, as well as finite affine and projective geometries—these two objects are analyzed and highlighted. Along the way, the reader contemplates fundamental questions such as: What is a straight line? What does parallel mean? What is distance? What is area? There is a strong focus on axiomatic structures throughout the text. While Euclid is a constant inspiration and the Elements is repeatedly revisited with substantial coverage of Books I, II, III, IV, and VI, non-Euclidean geometries are introduced very early to give the reader perspective on questions of axiomatics. Rounding out the thorough coverage of axiomatics are concluding chapters on transformations and constructibility. The book is compulsively readable with great attention paid to the historical narrative and hundreds of attractive problems.

This book is an English translation of a text written by Constantin Mihalescu, a retired artillery colonel and enthusiastic amateur mathematician. With the majority of the results obtained in the second half of the 19th century and the first half of the 20th century, this book was one of the most complete descriptions of geometry of its time. It contains a comprehensive collection of the most important properties of points, lines, and circles related to triangles and quadrilaterals, as they were known by the mid-1950s, and a rich assortment of problems to entice and inspire readers of all levels. Topics covered include the nine-point circle, the Simson line, the orthopolar triangles, the orthopole, the Gergonne and Nagel points, the Miquel point and circle, the Carnot circle, the Brocard points, the Lemoine point and circles, the Newton-Gauss line, and much more.

"Precalculus is intended for college-level precalculus students. Since precalculus courses vary from one institution to the next, we have attempted to meet the needs of as broad an audience as possible, including all of the content that might be covered in any particular course. The result is a comprehensive book that covers more ground than an instructor could likely cover in a typical one- or two-semester course; but instructors should find, almost without fail, that the topics they wish to include in their syllabus are covered in the text. Many chapters of OpenStax College Precalculus are suitable for other freshman and sophomore math courses such as College Algebra and Trigonometry; however, instructors of those courses might need to supplement or adjust the material. OpenStax will also be releasing College Algebra and Algebra and trigonometry titles tailored to the particular scope, sequence, and pedagogy of those courses."--Preface.

INTERNATIONAL BESTSELLER • A bestselling dystopian novel that tackles surveillance, privacy and the frightening intrusions of technology in our lives—a “compulsively readable parable for the 21st century” (Vanity Fair). When Mae Holland is hired to work for the Circle, the world’s most powerful internet company, she feels she’s been given the opportunity of a lifetime. The Circle, run out of a sprawling California campus, links users’ personal emails, social media, banking, and purchasing with their universal operating system, resulting in one online identity and a new age of civility and transparency. As Mae tours the open-plan office spaces, the towering glass dining facilities, the cozy dorms for those who spend nights at work, she is thrilled with the company’s modernity and activity. There are parties that last through the night, there are famous musicians playing on the lawn, there are athletic activities and clubs and brunches, and even an aquarium of rare fish retrieved from the Marianas Trench by the CEO. Mae can’t believe her luck, her great fortune to work for the most influential company in the world—even as life beyond the campus grows distant, even as a strange encounter with a colleague leaves her shaken, even as her role at the Circle becomes increasingly public. What begins as the captivating story of one woman’s ambition and idealism soon becomes a heart-racing novel of suspense, raising questions about memory, history, privacy, democracy, and the limits of human knowledge.

Key to Geometry introduces students to a wide range of geometric discoveries as they do step-by-step constructions. Using only a pencil, compass, and straightedge, students begin by drawing lines, bisecting angles, and reproducing segments. Later they do sophisticated constructions involving over a dozen steps. When they finish, students will have been introduced to 134 geometric terms and will be ready to tackle formal proofs. Includes: Book 2 of Key to Geometry
