Book Description
With over 300 entries from the ancient abacus to X-ray diffraction, as represented by a ca. 1900 photo of an X- ray machine as well as the latest research into filmless x- ray systems, this tour of the history of scientific instruments in multiple disciplines provides context and a bibliography for each entry. Newer conceptions of "instrument" include organisms widely used in research: e.g. the mouse, drosophila, and E. coli. Bandw photographs and diagrams showcase more traditional instruments from The Science Museum, London, and the Smithsonian's National Museum of American History.

Book Description
Runes and Their Secrets is a collection of articles written mainly in English by recognized scholars, examining a wide range of runological topics. The articles originated as papers read at an international runic symposium that was held in 2000. Jelling Runes embraces Danish runic inscriptions from the first to the sixteenth century, including such topics as the names of the runes, their chronology, literacy, runic coins, etc. There are also articles on the oldest runic research and runic magic. Several of the articles present brand new knowledge, for example about runic encryption of military and erotic secrets from the middle of the sixteenth century. (Formerly titled: Jelling Runes)

Book Description
Exploration tells the intriguing story of the navigators who crossed oceans to chart the coastlines of distant continents, the adventurers who traversed deserts and polar wastes, and the traders who sought new markets and commodities in faraway lands. The secrets of the planet and its living inhabitants have been unraveled thanks to the efforts made by these navigators and adventurers. This new, full-color book begins with a narration of the earliest seagoing ships and the vehicles that transported diplomats, warriors, and merchants around the Mediterranean region and later around the world. It explores the Vikings who terrorized Western Europe and colonized Greenland as well as the swift outrigger vessels that sailed from Asia to the islands of the Pacific. This accessible resource describes the development of navigational instruments to help on long journeys out of sight of landOCoincluding the sextant and compassOCoand explains how to calculate latitude and longitude."

Book Description
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.
