The steam engine, the major driver in the Industrial Revolution, underscores the importance of engineering in modern history. This beam engine is on display in the Technical University of Madrid.

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.

Earl William "Madman" Muntz (January 3, 1914 – June 21, 1987) was an American businessman and engineer who sold and promoted cars and consumer electronics in the United States from the 1930s until his death in 1987. He was a pioneer in television commercials with his oddball "Madman" persona; an alter ego who generated publicity with his unusual costumes, stunts, and outrageous claims. Muntz also pioneered car stereos by creating the Muntz Stereo-Pak, better known as the 4-track cartridge, a predecessor to the 8-track cartridge developed by Lear Industries.

He invented the practice that came to be known as Muntzing, which involved simplifying otherwise complicated electronic devices. Muntz produced and marketed the first black-and-white television receivers to sell for less than $100, and created one of the earliest functional widescreen projection TVs. He was credited with coining the abbreviation "TV" for television, although the term had earlier been in use in call letters for stations such as WCBS-TV. A high school dropout, Muntz made fortunes by selling automobiles, TV receivers, and car stereos and tapes. A 1968 Los Angeles Times article noted that in one year he sold $72 million worth of cars, that five years later he sold $55 million worth of TV receivers, and that in 1967 he sold $30 million worth of car stereos and tapes.

After his success as a used car salesman and with Kaiser-Frazer dealerships in Los Angeles and New York City, Muntz founded the Muntz Car Company, which made the "Muntz Jet", a sports car with jet-like contours. The car was manufactured between 1951 and 1953, although fewer than 400 were produced. (Full article...)

A fire sprinkler system is an active fire protection method, consisting of a water supply system, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected. Although historically only used in factories and large commercial buildings, systems for homes and small buildings are now available at a cost-effective price. Fire sprinkler systems are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings completely protected by fire sprinkler systems, over 96% of fires were controlled by fire sprinklers alone.
