Arthur Jones – författare

When Arthur Jones cocreated a reading series centered around ubiquitous Post-Its(r), the series struck a chord. It grew in popularity and was ultimately featured on a This American Life live simulcast broadcast across the nation.

Inspired by the series and spanning a wide and weird range of topics from an A-list roster of contributors, Post-It(r) Note Diaries captures everyday occurrences from a job interview gone hilariously awry and a nude run-in with a neighbor to hair-raising events like an overnight encounter at Nicholas Cage''s house (it''s not what you think!), and nearly drowning while trying to paddle across the East River in a homemade canoe. Post-It(r) Note Diaries is perfect for NPR addicts and fans of unique graphic favorites like Postsecret and Blankets.

Diarists include: John Hodgman, David Rakoff, Hanna Tinti, Arthur Bradford, Chuck Klosterman, Andrew Solomon, Starlee Kine, Kristen Schaal, Mary Roach and Andrew Bird.

Your small, everyday choices have eternal effect.

Philosophers from Plato to Pixar all assume we have a soul. But what does that actually mean, and why does it matter? In this bold new work, pastor Arthur Jones weaves together Scripture, history, theology, and pop culture to reclaim the ancient concept of a soul. A soul is not afterlife vapor but something very real and very specific: the resurrection of the body. Jesus'' message is that the kingdom of heaven is here now.

Some think the state of our soul only comes down to one big spiritual decision in life. However, while we depend on the grace of God, our soul is shaped by life''s little everyday decisions, not just a few big ones. These small decisions in our relationships, in our work, and for ourselves put us on a trajectory towards a more solid soul, or a more shriveled soul, one that is isolated from others and God.

The choices that we make in every moment lead us toward heaven or away from it. In Solid Souls, learn to see your life and the lives of others with eternal eyes, and learn how to live life in such a way that you find yourself on a trajectory toward fulfillment and flourishing. Discover how to make your soul more solid today.

This textbook develops the abstract algebra necessary to prove the impossibility of four famous mathematical feats: squaring the circle, trisecting the angle, doubling the cube, and solving quintic equations. All the relevant concepts about fields are introduced concretely, with the geometrical questions providing motivation for the algebraic concepts. By focusing on problems that are as easy to approach as they were fiendishly difficult to resolve, the authors provide a uniquely accessible introduction to the power of abstraction.

Beginning with a brief account of the history of these fabled problems, the book goes on to present the theory of fields, polynomials, field extensions, and irreducible polynomials. Straightedge and compass constructions establish the standards for constructability, and offer a glimpse into why squaring, doubling, and trisecting appeared so tractable to professional and amateur mathematicians alike. However, the connection between geometry and algebra allows the reader to bypass two millennia of failed geometric attempts, arriving at the elegant algebraic conclusion that such constructions are impossible. From here, focus turns to a challenging problem within algebra itself: finding a general formula for solving a quintic polynomial. The proof of the impossibility of this task is presented using Abel’s original approach.

Abstract Algebra and Famous Impossibilities illustrates the enormous power of algebraic abstraction by exploring several notable historical triumphs. This new edition adds the fourth impossibility: solving general quintic equations. Students and instructors alike will appreciate the illuminating examples, conversational commentary, and engaging exercises that accompany each section. A first course in linear algebra is assumed, along with a basic familiarity with integral calculus.
