Data graphics are used extensively to present information. Understanding graphics is a lot about understanding the data represented by the graphics, having a feel not just for the numbers themselves, the reliability and uncertainty associated with them, but also for what they mean. This book presents a practical approach to data visualisation with real applications front and centre. The first part of the book is a series of case studies, each describing a graphical analysis of a real dataset. The second part pulls together ideas from the case studies and provides an overview of the main factors affecting understanding graphics. Key Features: Explains how to get insights from graphics. Emphasises the value of drawing many graphics. Underlines the importance for analysis of background knowledge and context. Readers may be data scientists, statisticians or people who want to become more visually literate. A knowledge of Statistics is not required, just an interest in data graphics and some experience of working with data. It will help if the reader knows something of basic graphic forms such as barcharts, histograms, and scatterplots.
A visually intuitive approach to statistical data analysis Visual Statistics brings the most complex and advanced statistical methods within reach of those with little statistical training by using animated graphics of the data. Using ViSta: The Visual Statistics System-developed by Forrest Young and Pedro Valero-Mora and available free of charge on the Internet-students can easily create fully interactive visualizations from relevant mathematical statistics, promoting perceptual and cognitive understanding of the data's story. An emphasis is placed on a paradigm for understanding data that is visual, intuitive, geometric, and active, rather than one that relies on convoluted logic, heavy ma...
This book on energy physics and energy efficiency discusses two essential components of energy physics: the fundamentals and the criteria. It covers the historical basis of Carnot models, the thermostatic cycles of double-function heat pumps and the optimization of thermomechanical engines, and discusses the results of various investigations, bringing together a number of previous works. The latter half of this book introduces the concept of "Circular Thermoeconomics" and assesses the physical costs of recycling waste in increasingly complex industrial processes. It then goes on to present "Relative Free Energy", allowing us to create a new mathematical theory of thermodynamic costs in order to diagnose malfunctions in thermal systems. The book shows the progression of knowledge on the existence of successive energy, power and efficiency, and pairs this with the economic aspects, which are already becoming linked to growing environmental concerns.
Earth has become a huge mine, with a greater quantity and variety of fundamental mineral resources being extracted year after year. Technology, from electric cars to everyday electrical equipment, consume vast amounts of scarce raw materials. On a planet with limited resources, are these minerals being properly assessed? Will there be enough raw materials to meet the demand of a world population on track to reach 10 billion people? What will be the consequences of accelerated resource depredation? Will the planet one day become 'Thanatia', a resource-exhausted Earth? This book allows readers to understand the mineral heritage of the Earth, considering the demand for raw materials in society,...

The natural areas in the National Park System offer a fascinating variety -- lush forests, underwater nature trails along coral reefs, deserts in bloom, rivers through patches of wilderness, ever-shifting Atlantic barrier islands. They are precious habitat for wild creatures and vegetation, often serving as the last refuge against encroachment by civilization. Other parks tell about people: the ways of life, important events, and famous individuals from the time when humans first crosses from Asia into N. America some 13,000 years ago up to the present. This guide lists by state more than 170 lesser-known national parks, their accommodations, locations, and historical significance. Photos and maps.
