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.
Mechanical engineering is the discipline that applies engineering, physics, engineering mathematics, and materials science principles to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering disciplines.
The two main purposes of mechanical engineering are: first, to design and make tools and equipment for turning out machinery required by all branches of engineering, industry, and commerce, and, second, to design and manufacture, by means of said tools and equipment.

There are two laws discrete,
Law for man, and law for thing;
The last builds town and fleet,
But it runs wild,
And doth the man unking.
Ralph Waldo Emerson, Ode, Inscribed to William H. Channing
Incorrigible humanity, therefore, led astray by the giant Nimrod, presumed in its heart to outdo in skill not only nature but the source of its own nature, who is God; and began to build a tower in Sennaar, which afterwards was called Babel (that is, 'confusion'). By this means human beings hoped to climb up to heaven, intending in their foolishness not to equal but to excel their creator.
Dante Alighieri, De vulgari eloquentia, Chapter VII
