An unruly cast of emotions come alive in this romping dreamworld, a place Maurice Sendak's Wild Things could call home Curiosity, a lithe and floppy-eared creature, perches above the open world and gazes out with a zippy blend of hope, wonder, and longing. From the tip of a chimney, we bound into the quiet and mischievous world of feelings, meeting a troupe of tufted creatures as we go. Sympathy helps snails cross a sidewalk to safety, fear pirouettes in an attempt to camouflage with wallflowers, and pleasure reclines across a doily-donned reading chair, sipping a cup of tea. Elsewhere, our insecurities - pesky, cavorting beings - build intricate cages and stride about with clattering sets of keys. Tina Oziewicz's words hum with truth, and Aleksandra Zajac's illustrations bloom and burst with charming details like a sail constructed out of a pair of billowing long johns or a red slipper falling from a contented paw. Taking in the perfect harmony of this book is like taking a long gulp

The primary object of this manual is to build an understanding of the principles of computer operations and the use of computers in the laboratory. While the development of applications for computers has been rapid since their introduction, the principles of computer operation and their use in sensing and control have remained stable. Those are the primary subjects of this book, throughout which a gradual understanding of what goes on inside a computer is developed. The laboratory provides a vital experience in linking theory with physical reality, and all of the computer work is done in the context of doing experiments. The IBM-PC design is used as the basis for the book. The internal design of this machine is slightly more complicated than earlier personal computers, but it is still simple enough to be quickly learned. The computer can be directly controlled by proper programming, and offers considerably more power than earlier designs. The IBM design also has expansion slots which m

Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things.Among the many things expectant parents are told to buy, none is a more visible symbol of status and parenting philosophy than a stroller. Although its association with wealth dates back to the invention of the first pram in the 1700s, in recent decades, four-figure strollers have become not just status symbols but cultural identifiers. There are sleek jogging strollers for serious athletes, impossibly compact strollers for parents determined to travel internationally with pre-ambulatory children, and those featuring a ride-on kick board or second, less “babyish” seat, designed with older siblings in mind. Despite the many models available, we are all familiar with the image of a harried mother struggling to use a stroller of any kind in a public space that does not accommodate it. There are anti-stroller evangelists, fervently preaching the gospel of baby wearing and attachment pa

A guide to computational thinking education, with a focus on artificial intelligence literacy and the integration of computing and physical objects. Computing has become an essential part of today’s primary and secondary school curricula. In recent years, K–12 computer education has shifted from computer science itself to the broader perspective of computational thinking (CT), which is less about technology than a way of thinking and solving problems―“a fundamental skill for everyone, not just computer scientists,” in the words of Jeanette Wing, author of a foundational article on CT. This volume introduces a variety of approaches to CT in K–12 education, offering a wide range of international perspectives that focus on artificial intelligence (AI) literacy and the integration of computing and physical objects. The book first offers an overview of CT and its importance in K–12 education, covering such topics as the rationale for teaching CT; programming as a general problem-solving

This Element critically surveys the full range of G. E. Moore's ethical thought, including: (1) his rejection of naturalism in favor of the view that 'good' designates a simple, indefinable property, which cannot be identified with or reduced to any other property; (2) his understanding of intrinsic value, his doctrine of organic wholes, his repudiation of hedonism, and his substantive account of the most important goods and evils; and (3) his critique of egoism and subjectivism and his elaboration of a non-hedonistic variant of utilitarianism that, among other things, creatively blends aspects of act- and rule-oriented versions of that theory.

The hosts of the podcast Stuff They Don’t Want You to Know, Ben Bowlin, Matthew Frederick, and Noel Brown discern conspiracy fact from conspiracy fiction in this exposé on stuff the government doesn’t want you to know.Conspiracies didn’t always seem so clear and present. It used to be that people with tin-foil hats who were convinced of secret messages coming through the radio were easily disregarded as kooks and looney tunes. But these days, conspiracies feel alive and well. From internet rumors to lying politicians to the tinderbox that is social media, it’s become remarkably clear that a vast swath of people believe really bonkers things.Why is that? How did these theories proliferate? Is there a kernel of truth to it or are they fully fiction? Ben Bowlin, Matt Frederick, and Noel Brown are the hosts of the popular iHeart podcast that seeks to answer these questions. With cool heads and extensive research, they regularly break down the wildest conspiracy theories: from chemtrails an

Organizations and businesses strive toward excellence, and solutions to problems are based mostly on judgment and experience. However, increased competition and consumer demands require that the solutions be optimum and not just feasible. Theory leads to algorithms. Algorithms need to be translated into computer codes. Engineering problems need to be modeled. Optimum solutions are obtained using theory and computers, and then interpreted. Revised and expanded in its third edition, this textbook integrates theory, modeling, development of numerical methods, and problem solving, thus preparing students to apply optimization to real-world problems. This text covers a broad variety of optimization problems using: unconstrained, constrained, gradient, and non-gradient techniques; duality concepts; multi-objective optimization; linear, integer, geometric, and dynamic programming with applications; and finite element-based optimization. It is ideal for advanced undergraduate or graduate cours
