This one of a kind encyclopedia presents the entire field of technology from rudimentary agricultural tools to communication satellites in this first of its kind reference source. Following an introduction that discusses basic tools, devices, and mechanisms, the chapters are grouped into five parts that provide detailed information on materials, power and engineering, transportation, communication and calculation, and technology and society, revealing how different technologies have together evolved to produce enormous changes in the course of history | PART FIVE TECHNOLOGY AND SOCIETY application to domestic machines until the 1930s and factory machines tended for some years to be driven from overhead shafting. FASTENINGS Fastenings are an essential component for the majority of garments and one in which great advances have been made in recent years.
