Step-by-step instructions to building more than 30 fascinating devices are included in this book for workbench warriors and grown-up geeks. Detailed illustrations and diagrams explain how to construct a simple radio with a soldering iron, a few basic circuits, and three shiny pennies. Instructions are included for a rotary steam engine that requires a candle, a soda can, a length of copper tubing, and just 15 minutes. To use optics to roast a hot dog, no electricity or stove is required, just a flexible plastic mirror, a wooden box, a little algebra, and a sunny day. Also included are experiments most science teachers probably never demonstrated, such as magnets that levitate in midair, metals that melt in hot water, a Van de Graaff generator made from a pair of empty soda cans, and lasers that transmit radio signals. Every experiment is followed by an explanation of the applicable physics or chemistry.
This topical and exciting textbook describes fisheries exploitation, biology, conservation and management, and reflects many recent and important changes in fisheries science. These include growing concerns about the environmental impacts of fisheries, the role of ecological interactions in determining population dynamics, and the incorporation of uncertainty and precautionary principles into management advice. The book draws upon examples from tropical, temperate and polar environments, and provides readers with a broad understanding of the biological, economic and social aspects of fisheries ecology and the interplay between them. As well as covering 'classical' fisheries science, the book focuses on contemporary issues such as industrial fishing, poverty and conflict in fishing communities, marine reserves, the effects of fishing on coral reefs and by-catches of mammals, seabirds and reptiles. The book is primarily written for students of fisheries science and marine ecology, but should also appeal to practicing fisheries scientists and those interested in conservation and the impacts of humans on the marine environment. particularly useful are the modelling chapters which explain the difficult maths involved in a user-friendly manner describes fisheries exploitation, conservation and management in tropical, temperate and polar environments broad coverage of 'clasical' fisheries science emphasis on new approaches to fisheries science and the ecosystem effects of fishing examples based on the latest research and drawn from authors' international experience comprehensively referenced throughout extensively illustrated with photographs and line drawings
When it comes to chemistry, most kids have more questions than answers. Why do you get cavities when you eat too much sugar? How does sun block protect your skin from getting a sunburn? What makes soda so fizzy? And why do you need antifreeze in your car? Teenager Alexa Coelho quizzed her neighbor, chemist Simon Field, with hundreds of perplexing questions, and now she has the answers. Field covers a wide variety of concepts from simple to complex, but always with straightforward, easy-to-understand explanations. And for those readers who want to see chemistry in action, Why Is Milk White? also includes a dozen unique experiments to try at home. Lift latent fingerprints from a &“crime scene&” using super glue (for a glass or smooth surface) or iodine (for paper). Hollow out the zinc interior of a penny using muriatic acid, leaving only a thin copper shell. Conduct a paper chromatography experiment to separate food coloring into its component dyes. Or use easy-to-find chemicals to create plastic &“slime,&” Silly Putty, or a bouncing ball. This book is the perfect resource for budding scientists everywhere.
The Boatyard Book is a practical, comprehensive reference manual that provides sensible, accessible advice for boatowners on planning and carrying out annual maintenance, repairs, upgrades and refits of sailing yachts and motorboats, up to 20 metres in length. Beginning with all the information owners will need to care for their boat, including how to budget and plan tasks to be done through the year, The Boatyard Book goes on to help them choose the best boatyard for their needs, then provides essential how-to reference material and ideas for a comprehensive range of projects large and small to be carried out ashore. There's advice and tips from highly respected boatyard owners, specialists and surveyors, as well as from the author's own 25 years' experience of boat ownership, all fully illustrated with step-by-step photos and illustrations. Topics covered include: - laying up - hull and deck care - mast and rigging - sail care - engines - electrics - maintenance of plumbing and gas systems - more complex projects, including re-wiring a boat, overhauling an engine, how to treat osmosis and how to go about a complete refit. This is a book to be kept at the yard, or on the boat, and used time and time again by those who are either happy to keep things ticking along with the minimum of effort or by those who want to get stuck into bigger projects.
This book combines primary materials with expert commentary, demonstrating the interaction between law and practice in the UN organisation, as well as the possibilities and limitations of multilateral institutions in general. Each chapter begins with a short introductory essay by the authors that describes how the documents that follow illustrate a set of legal, institutional, and political issues relevant to the practice of diplomacy and the development of public international law through the United Nations. This second edition updates the materials in the first edition and introduces new features that reflect a changing global landscape.
Originally published 1969. This reprints the second edition of 1973, with updated reading list and bibliography.This volume sets the movement towards comprehensive education against its historical background and discuss the main reasons for the decision to establish a national comprehensive system.
The world of the Founding Fathers was also a postrevolutionary society, in whose streets people of all social classes jostled in festivals and parades that expressed a vibrant popular politics. Simon Newman's book is as lively as the tumultuous political culture he has mapped."--Linda K. Kerber, author of Women of the Republic

The English were punished in many different ways in the five centuries after 1500. This collection stretches from whipping to the gallows, and from the first houses of correction to penitentiaries. Punishment provides a striking way to examine the development of culture and society through time. These studies of penal practice explore violence, cruelty and shame, while offering challenging new perspectives on the timing of the decline of public punishment, the rise of imprisonment and reforms of the capital code.
