This exciting Greenvill Collins biography is about seventeenth century navigation, focusing for the first time on mathematics practised at sea. This monograph argues the Restoration kings’, Charles II and James II, promotion of cartography for both strategy and trade. It is aimed at the academic, cartographic and larger market of marine enthusiasts. Through shipwreck and Arctic marooning, and Dutch and Spanish charts, Collins evolved a Prime Meridian running through Charles’s capital. After John Ogilby’s successful Britannia, Charles set Collins surveying his kingdom’s coasts, and James set John Adair surveying in Scotland. They triangulated at sea. Subsequently, Collins persuaded James to sustain his dead brother’s ambition. This, the British coast’s first survey took six years. After James’s flight, and William III’s invasion, Collins lead the royal yacht squadron for six years more, garnering funds to publish Great Britain’s Coasting Pilot. The Admiralty and civic institutions subsidised what became his own pilot. Collins aided Royal Society members in their investigations, and his new guide remained vital to navigators through the century following. Charles’s cartographic promotion bloomed the most spectacularly in the atlases of Ogilby, Collins and John Flamsteed for roads, harbours, and stars.

Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.

After conducting a comprehensive literature search, the authors undertook a meta-analysis to examine the association between correctional education and reductions in recidivism, improvements in employment after release from prison, and other outcomes. The study finds that receiving correctional education while incarcerated reduces inmates' risk of recidivating and may improve their odds of obtaining employment after release from prison.
