This is the second of a two-volume work covering the electrical principles syllabuses of all of the major examining bodies including the City & Guilds of London Institute's electrical craft courses. It is also suitable for a wide range of other courses, including the first three years of the BTEC electrical series. Great care has been taken to ensure that the text fully covers the content of the syllabuses concerned, both as published and as interpreted by the examiners in the past. The book is well illustrated with almost 200 line diagrams and photographs. Theories are explained with the help of almost 100 worked examples, an important aid to understanding the practical applications, and there are more than 300 graded exercises for which numerical answers are provided as well as nearly 250 multiple choice questions with solutions. These features make the book ideal as a class text as well as being particularly suitable for private study. A complete list of symbols, abbreviations and units is included, along with eight tables of relevant data and introduction to SI units, this system being used throughout. Each chapter concludes with a summary of the formulas introduced in it. The book will also be useful to practicing technicians wishing to extend their grasp of electrical principles to meet the rapidly expanding requirements of the industry.

Documenting the species that have emerged, disappeared and been reborn over the millennia since the Cambrian Explosion, Lost Animals is the story of life on Earth. Over 520 million years ago, all the major animal groups – molluscs, worms, crustaceans, vertebrates – appear in the fossil record in what is, geologically speaking, the blink of an eye. As well as the animals we're familiar with today, evolution also experimented with now-obsolete body forms. Once, the world was a blank slate, but as this slate filled up, some lines were erased while others carried on to this day. Beautifully illustrated with artist's interpretations, photographs of fossils and excavations and scientific drawings, Lost Animals brings back to life some of the most charismatic creatures to inhabit the planet, as well as those representing an important link or leap in evolutionary terms. Zoologist Dr John Whitfield discusses those species we have lost, are only just discovering and those thought extinct until rediscovered, and the attempts to conserve and resurrect others.

How to get a good reputation--deserved or not --and why we care what other people think

Why does a fish only bite another fish if no one else is watching? Why do people overshare online? Why do some people meet trivial insults with extreme violence? Why do so many gods have multiple eyes? In "People Will Talk," science writer John Whitfield shows how reputation helps answer all of these questions, and more. What is the secret to getting get a good reputation? Unfortunately, there's more to reputation than being a good person or being good at what you do. Your reputation belongs to other people, and it's created by what they say about you behind your back. You have a good reputation only if you have a strong social network--a large and close-knit network of friends, family, and allies--to spread good news about you and shout down ugly rumors. If you've ever wondered why we care about the lives of celebrities, why young men publicly upload to the Internet pictures of themselves engaged in drunken or dangerous antics, how to make the "honor system" a little more widely honored, how to keep politicians honest, or what keeps gossip going, reputation will give you a clue.Almost from the moment we are born, we are trying to work out whom we can trust and trying to make others think the best of us. We carry on doing so throughout life, even when we don't realize it, every time we meet another person in business, friendship, or romance; every time we read celebrity gossip; and every time we tweak our Facebook profiles. Whether you're buying a car or selling one, looking for a job or hiring, asking someone out on a date or deciding whether to accept the invitation, reputation matters.

Read "People Will Talk" and discover how to polish your own reputation, understand what you hear about others, and make the most of both.
