One Zentangle A Day is a beautiful interactive book teaching the principles of Zentangles as well as offering fun, related drawing exercises. Zentangles are a new trend in the drawing and paper arts world. The concept was started by Rick Roberts and Maria Thomas as a way to practice focus and meditation through drawing, by using repetitive lines, marks, circles, and shapes. Each mark is called a "tangle," and you combine various tangles into patterns to create "tiles" or small square drawings. This step-by-step book is divided into 6 chapters, each with 7 daily exercises. Each exercise includes new tangles to draw in sketchbooks, teaches daily tile design, and offers tips on related art principles, and contains an inspirational "ZIA" (Zentangle Inspired Art) project on a tile that incorporates patterns, art principals, and new techniques.
Lou Brunswick, one of the winningest baseball coaches in Ohio history, tells of playing professional baseball, losing a brother in the Korean War and winning more than 750 high school baseball games. This emotional story tells of how one man changed the lives of many.
With the advent of approximation algorithms for NP-hard combinatorial optimization problems, several techniques from exact optimization such as the primal-dual method have proven their staying power and versatility. This book describes a simple and powerful method that is iterative in essence and similarly useful in a variety of settings for exact and approximate optimization. The authors highlight the commonality and uses of this method to prove a variety of classical polyhedral results on matchings, trees, matroids and flows. The presentation style is elementary enough to be accessible to anyone with exposure to basic linear algebra and graph theory, making the book suitable for introductory courses in combinatorial optimization at the upper undergraduate and beginning graduate levels. Discussions of advanced applications illustrate their potential for future application in research in approximation algorithms.
