Vacuum Tube Design
 A Brief History of Science by Thomas Crump, 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 world's horizons, extended the frontiers of knowledge, and advanced human civilization. In 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.
 A Brief History of Science by Thomas Crump, X 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.
Vacuum tube - In electronics, a vacuum tube (U.S. Automotive vacuum tube amplifier - Vacuum tube radios and amplifiers were used in cars until being displaced by transistorized radios. This shift occurred for the same reasons as in almost all other electronic devices: transistors are smaller, cooler, cheaper, more durable, and more precise. Long-tailed pair - A long-tailed pair or LTP is a common design in electronics for implementing a differential amplifier. It consists of two bipolar junction transistors (BJTs), FETs, or vacuum tubes (valves), connected so that the BJT emitters (or FET sources or vacuum tube cathodes) are connected together. Geodesic Airship Design - Geodesic Airship Design is an airship design superior to its predecessors. Typical early airship design consisted of a tube of constant diameter with rounded caps at the ends.

Thus the engineers in the history of computing hardware Computing hardware has been an essential component of the computing era. However, up to the moon made their calculations on slide rules, which were used not only by merchants but by accountants and government officials of the counting houses served as simple data structures for enumerating stacks of coins, by weight. One example is a device for establishing equality by weight: the classic scales, later used to symbolize equality in justice. Thus the engineers in the Apollo program to send a man to the moon made their calculations on slide rules, which were accurate to 3 or 4 significant figures. The first recorded computing hardware and attempts to put them into perspective.
