Morija Printing Works is a printing and publishing company in Morija, Lesotho, founded by missionary Adolphe Mabille in 1861 and among the oldest presses in Southern Africa.

Morison equation

The Morison equation is a semi-empirical formula for wave-induced forces on slender submerged structures such as piles and risers, introduced by Morison, Johnson, and Schaaf in 1950.

Morlais

Morlais is a tidal stream energy project run by Menter Môn on 35 km² of seabed off Holy Island, Anglesey, Wales, with potential for up to 240 MW.

Morning star (weapon)

The morning star, from the German Morgenstern, is a medieval weapon with a spiked head mounted directly on a shaft, often confused with the ball-and-chain military flail.

Morning-glory spillway

A morning-glory spillway, also called a glory hole or bell-mouth spillway, is a funnel-shaped dam spillway where water flows over a circular weir lip, down a shaft, and through a tunnel.

Morphing (computer graphics)

Morphing is a computer graphics technique that transforms one image or shape into another by warping features into alignment and blending colors, producing in-between frames.

Morphing wing mechanism

A morphing wing mechanism is a structural and actuation system that lets an aircraft wing change shape smoothly in flight, replacing hinged control surfaces with flexible, jointless structures.

Morphological computation

Morphological computation is a concept in robotics and embodied cognition holding that a body's form and dynamics can perform work otherwise left to a central controller, underpinning soft robotics.

Morphological filtering

Morphological filtering is a nonlinear image-processing technique that probes an image with a small template called a structuring element, built from erosions and dilations, to remove noise, enhance shapes, and extract features.

MorphOS

MorphOS is a lightweight desktop operating system for PowerPC-based computers, descended from classic AmigaOS and able to run legacy Amiga applications through a built-in JIT compiler.

Morris Canal

The Morris Canal was a 19th-century anthracite-coal canal across northern New Jersey, running from Phillipsburg on the Delaware River to Jersey City, and remembered for its inclined planes.

Morris Chang (张忠谋)

Morris Muskat

Morris Muskat (1906–1998) was an American petroleum engineer and physicist who established the mathematical theory of fluid flow through porous media and, with it, the field of petroleum reservoir engineering.

Morris worm

The Morris worm, also known as the Great Worm, was a self-replicating program released by Robert Tappan Morris in 1988, the first major worm on the Internet.

Morrough P. O'Brien

Morrough P. O'Brien, also known as Morrough Parker O'Brien, was an American engineer and dean of engineering at UC Berkeley, regarded as the founder of modern coastal engineering.

Morrough Parker O'Brien

Morrough Parker O'Brien (1902–1988) was an American engineer, professor, and dean of engineering at the University of California, Berkeley, and a founder of modern coastal engineering.

Morrow Batteries

Morse code abbreviations

Morse code abbreviations: CW shorthand (abbreviations, Q codes, Z codes, 92 Code numerals, prosigns) used since 1844 telegraphy; standardized partly by ITU-R M.1172/M.1677-1, partly amateur convention; distinct from cable code books like the Phillips Code.

Morse key

A Morse key, also called a telegraph key, is a hand-operated electrical switch that sends messages in Morse code, first made practical by Alfred Vail in 1844.

Mortar (masonry)

Mortar is a paste of sand, a binder such as lime or Portland cement, and water, used in masonry to bond brick, stone, and block and seal the joints between them.

Mortar (weapon)

A mortar is a short-barreled, muzzle-loaded artillery weapon that fires shells in a high arc, dropping rounds into trenches and dead ground that flat-trajectory guns cannot reach.
