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.
Interior
But it is not only of space in the Church which we ought to be jealous, but also of the interior of the house of God in us, so that it might not become a house of merchandise, or a den of robbers.
Ambrose, Commentary on John 2:16, Exposition of the Psalms of David 118 (PL 15 1457B)
