This classic guide offers clear, concise instruction in the basics as well as the finer points of pencil drawing. Appropriate for beginning and intermediate students, it features sixty-six well-chosen illustrations that encompass a wide range of subjects — mainly architectural, but also people, animals, and landscapes — and demonstrate a tremendous variety of techniques. An architect, painter, art director, and teacher, Arthur L. Guptill wrote several popular books on drawing. He begins this two-part treatment, aimed at architects, artists, and students, with discussions of drawing objects in outline and in light and shade, the principles of freehand perspective, methods of cast and life drawing, and sketching animals. The second part examines the choice of subjects and drawing in outline and in flat and graded tones. The important subject of composition receives considerable attention, with particular focus on unity and balance. Additional topics include working from photographs and from nature, the representation of buildings — including exteriors, interiors, and street scenes — and portraying details and accessories, from furniture, draperies, doors, and windows to clouds, water, and trees.

While many books explain the how of bitcoin, The Internet of Money delves into the why of bitcoin. Acclaimed information-security expert and author of Mastering Bitcoin, Andreas M. Antonopoulos examines and contextualizes the significance of bitcoin through a series of essays spanning the exhilarating maturation of this technology. Bitcoin, a technological breakthrough quietly introduced to the world in 2008, is transforming much more than finance. Bitcoin is disrupting antiquated industries to bring financial independence to billions worldwide. In this book, Andreas explains why bitcoin is a financial and technological evolution with potential far exceeding the label "digital currency." Andreas goes beyond exploring the technical functioning of the bitcoin network by illuminating bitcoin's philosophical, social, and historical implications. As the internet has essentially transformed how people around the world interact and has permanently impacted our lives in ways we never could have imagined, bitcoin--the internet of money--is fundamentally changing our approach to solving social, political, and economic problems through decentralized technology.
