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
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
At most technology companies, you'll reach Senior Software Engineer, the career level for software engineers, in five to eight years. At that career level, you'll no longer be required to work towards the next pro? motion, and being promoted beyond it is exceptional rather than ex? pected. At that point your career path will branch, and you have to decide between remaining at your current level, continuing down the path of technical excellence to become a Staff Engineer, or switching into engineering management. Of course, the specific titles vary by company, and you can replace "Senior Engineer" and "Staff Engineer" with whatever titles your company prefers.Over the past few years we've seen a flurry of books unlocking the en? gineering management career path, like Camille Fournier's The Man? ager's Path, Julie Zhuo's The Making of a Manager, Lara Hogan's Re? silient Management and my own, An Elegant Puzzle. The manage? ment career isn't an easy one, but increasingly there are maps avail? able for navigating it.On the other hand, the transition into Staff Engineer, and its further evolutions like Principal and Distinguished Engineer, remains chal? lenging and undocumented. What are the skills you need to develop to reach Staff Engineer? Are technical abilities alone sufficient to reach and succeed in that role? How do most folks reach this role? What is your manager's role in helping you along the way? Will you enjoy being a Staff Engineer or you will toil for years to achieve a role that doesn't suit you?"Staff Engineer: Leadership beyond the management track" is a pragmatic look at attaining and operate in these Staff-plus roles.

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.
