Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. 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.

The term engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise". (Full article...)

Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. The word engineer (Latin ingeniator) is derived from the Latin words ingeniare ("to contrive, devise") and ingenium ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional practice (culminating in a project report or thesis) and passage of engineering board examinations.

Grant's Canal (also known as Williams's Canal) was an incomplete military effort to construct a canal through De Soto Point in Louisiana, across the Mississippi River from Vicksburg, Mississippi. During the American Civil War, United States Navy forces attempted to capture the Confederate-held city of Vicksburg in 1862, but were unable to do so with army support. Union Brigadier General Thomas Williams was sent to De Soto Point with 3,200 men to dig a canal capable of bypassing the strong defenses around Vicksburg. Despite help from local plantation slaves, disease and falling river levels prevented Williams from successfully constructing the canal, and the project was abandoned until January 1863, when Union Major General Ulysses S. Grant took an interest in the project.

Grant attempted to solve some of the issues inherent with the canal by moving the upstream entrance to a spot with a stronger current, but heavy rains and flooding that broke a dam prevented the project from succeeding. Work was abandoned in March, and Grant eventually used other methods to capture Vicksburg, whose Confederate garrison surrendered on July 4, 1863. In 1876, the Mississippi River changed course to cut across De Soto Point, eventually isolating Vicksburg from the river, but the completion of the Yazoo Diversion Canal in 1903 restored Vicksburg's river access. Most of the canal site has since been destroyed by agriculture, but a small section survives. This section was donated by local landowners to the National Park Service and became part of Vicksburg National Military Park in 1990. A 1974 article in The Military Engineer calculated that the canal would likely have been successful if the dam at the downstream end of the canal had been opened. (Full article...)

A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. The name derives from the method of divided differences, a way to interpolate or tabulate functions by using a small set of polynomial coefficients. Most mathematical functions commonly used by engineers, scientists and navigators, including logarithmic and trigonometric functions, can be approximated by polynomials, so a difference engine can compute many useful tables of numbers. The historical difficulty in producing error-free tables by teams of mathematicians and human "computers" spurred Charles Babbage's desire to build a mechanism to automate the process. It is considered to be the world's first computer.
