Engineering
Engineering is the creative application of science, mathematical methods, and empirical evidence to the innovation, design, construction, operation and maintenance of structures, machines, materials, devices, systems, processes, and organizations. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering.
Economics
To have peace and not war, the drift toward a war economy, as facilitated by the moves and the demands of the sophisticated conservatives, must be stopped; to have peace without slump, the tactics and policies of the practical right must be overcome. The political and economic power of both must be broken. The power of these giants of main drift is both economically and politically anchored; both unions and an independent labor party are needed to struggle effective.
C. Wright Mills, The New Men of Power (1948).
Engineering
Engineering is the art of directing the great sources of power in nature for the use and convenience of man.
Thomas Tredgold (1828), used in the Royal Charter of the Institution of Civil Engineers (ICE) published in: The Times, London, article CS102127326, 30 June 1828.
