The history of engineering can be roughly divided into four overlapping phases, each marked by a revolution and they are: Pre-scientific revolution , (The prehistory of modern engineering features ancient master builders and Renaissance engineers such as Leonardo da Vinci.) Industrial revolution , (From the eighteenth through early nineteenth century, civil and mechanical engineers changed from practical artists to scientific professionals.) Second industrial revolution (In the century before World War II, chemical, electrical, and other science-based engineering branches developed electricity, telecommunications, cars, airplanes, and mass production.) and Information revolution (As engineering science matured after the war, microelectronics, computers, and telecommunications jointly produced information technology.) a. Briefly describe each of this phases and their corresponding impact. b. By referring to specific engineering practices or your group’s project, name THREE engineering achievements and explain the reasons how engineers can help advance better living conditions for mankind. 2

The forerunners of engineers, practical artists and craftsmen,  proceeded mainly by trial and error.   Yet tinkering combined with imagination produced many  marvelous devices.   Many ancient monuments cannot fail to incite admiration.  The  admiration is embodied in the name “engineer” itself.  It  originated in the eleventh century from the Latin  ingeniator meaning one with  ingenium , the ingenious one.  The name,  used for builders of ingenious fortifications or makers of  ingenious devices, was closely related to the notion of  ingenuity, which was captured in the old meaning of “engine”  until the word was taken over by steam engines and its like.   Leonardo da Vinci bore the official title of  Ingegnere  Generale.   His notebooks reveal that some Renaissance  engineers began to ask systematically  what  works and  why . 3
