Up and Down Stairs brings to life this hierarchy, showing how large numbers of people lived together under strict segregation and how sometimes this segregation was broken, as with the famous marriage of a squire to his dairymaid at Uppark. Jeremy Musson captures the voices of the servants who ran these vast houses and made them work. From unpublished memoirs to letters, wages, and newspaper articles, he pieces together their daily lives from the Middle Ages to the 20th century. The story of domestic servants is inseparable from the story of the country house as an icon of power, civilization, and luxury. This is particularly true with the great estates such as Chatsworth, Hatfield, Burghley and Wilton. Jeremy Musson looks at how these grand houses were, for centuries, admired and imitated around the world.

    With sixteen pages of photographs, and vivid vignettes of scientists and their inventions, Crump guides readers through early attempts to measure time and space—from astronomical charts and calendars to Arabic numerals and algebraic notation—before he examines the birth of an essentially modern technology in the 1600s. With Galileo's telescopic exploration of the skies at the beginning of the seventeenth century and Newton's experiments with the prism and light at its end, the optical instruments fundamental to all scientific research had been invented. Crump then proceeds to electromagnets, cathode tubes, thermometers, vacuum pumps, X rays, accelerators, semiconductors, microprocessors, and instruments currently being designed to operate in subzero temperatures. Here, then, in an accessible, succinctly narrated volume, is the enduring human quest for knowledge through technology. Here, too, is the proof that what is knowable is, and has always been, far more compelling than what is known. "[Crump] provides lively summaries of the progress in different fields, and succeeds in breathing new life into familiar stories."—The Economist "Fascinating reading."—Publishers Weekly

    The LEGO MINDSTORMS NXT 2.0 Discovery Book is the complete, illustrated, beginner's guide to MINDSTORMS that you've been looking for. The crystal clear instructions in the Discovery Book will show you how to harness the capabilities of the NXT 2.0 set to build and program your own robots. Author and robotics instructor Laurens Valk walks you through the set, showing you how to use its various pieces, and how to use the NXT software to program robots. Interactive tutorials make it easy for you to reach an advanced level of programming as you learn to build robots that move, monitor sensors, and use advanced programming techniques like data wires and variables. You'll build eight increasingly sophisticated robots like the Strider (a six-legged walking creature), the CCC (a climbing vehicle), the Hybrid Brick Sorter (a robot that sorts by color and size), and the Snatcher (an autonomous robotic arm). Numerous building and programming challenges throughout encourage you to think creatively and to apply what you've learned as you develop the skills essential to creating your own robots.Requirements: One LEGO MINDSTORMS NXT 2.0 set (#8547)FeaturesA complete introduction to LEGO MINDSTORMS NXT 2.0 Building and programming instructions for eight innovative robots 50 sample programs and 72 programming challenges (ranging from easy to hard) encourage you to explore newly learned programming techniques 15 building challenges expand on the robot designs and help you develop ideas for new robotsWho is this book for?
