History of Thermometer

This history of the thermometer includes controversy about its invention, the story of different scales, Fahrenheit and centigrade, and the history of the gradual scientific then popular understanding of the concept of temperature. Not until 1800 did people interested in thermometers begin to see clearly what they were measuring, and the impetus for improving thermometry came largely from study of the weather -- the liquid-in-glass thermometer became the meteorologist's instrument before that of the chemist or physicist. This excellent introductory study follows the development of indicating and recording thermometers until recent times, emphasizing meteorological applications.

From the gnomons and sundials of ancient times to the 26-kilometer underground particle accelerator of the twenty-first century, this fascinating and enlightening volume by mathematician and anthropologist Thomas Crump shows how science has continually redefined the worlds horizons, extended the frontiers of knowledge, and advanced human civilization. With sixteen pages of photographs, and vivid vignettes of scientists and their inventions, Crump guides readers through early attempts to measure time and spacefrom astronomical charts and calendars to Arabic numerals and algebraic notationbefore he examines the birth of an essentially modern technology in the 1600s. With Galileos telescopic exploration of the skies at the beginning of the seventeenth century and Newtons 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.

History of English local history - The history of English local history begins with the incidental material in the writings of Bede and runs through early modern antiquarianism, and twentieth century academicism to contemporary pluralist synthesis of specialisms.

Adverse Credit History - Adverse Credit History, also called sub-prime credit history, non-status credit history, impaired credit history, poor credit history and bad credit history, is a credit history that is judged as being adverse as the applicant has a history of unsatisfactory credit transactions. The term can apply to a corporate credit history but is more frequently used in relation to personal credit.

Alternative history (fiction) - Alternative history or alternate history is a subgenre of speculative fiction (or some would say, of science-fiction), that is set in a world in which history has diverged from history as it is generally known; more simply put, alternate history asks the question, "What If history had developed differently?" Most works that employ this rubric are set in factful historical contexts, yet feature several social, geopolitical or industrial circumstances that developed differently or at a different pace from our own, ...
