- irish republican army — an underground Irish nationalist organization founded to work for Irish independence from Great Britain: declared illegal by the Irish government in 1936, but continues activity aimed at the unification of the Republic of Ireland and Northern Ireland. Abbreviation: IRA, I.R.A.
- lady windermere's fan — a comedy (1892) by Oscar Wilde.
- law of thermodynamics — any of three principles variously stated in equivalent forms, being the principle that the change of energy of a thermodynamic system is equal to the heat transferred minus the work done (first law of thermodynamics) the principle that no cyclic process is possible in which heat is absorbed from a reservoir at a single temperature and converted completely into mechanical work (second law of thermodynamics) and the principle that it is impossible to reduce the temperature of a system to absolute zero in a finite number of operations (third law of thermodynamics)
- lay at someone's door — a movable, usually solid, barrier for opening and closing an entranceway, cupboard, cabinet, or the like, commonly turning on hinges or sliding in grooves.
- limit-proportionality — elastic limit.
- macintosh file system — (file system) A file on the Macintosh consists of two parts, called forks. The "data fork" contains the data which would normally be stored in the file on other operating systems. The "resource fork" contains a collection of arbitrary attribute/value pairs, including program segments, icon bitmaps, and parametric values. Yet more information regarding Macintosh files is stored by the Finder in a hidden file, called the "Desktop Database". Because of the complications in storing different parts of a Macintosh file in non-Macintosh file systems that only handle consecutive data in one part, it is common to only send the Data fork or to convert the Macintosh file into some other format before transferring it.
- magnetic flux density — Also called magnetic flux density. a vector quantity used as a measure of a magnetic field. Symbol: B.
- magnetic permeability — permeability (def 2).
- magnetofluid dynamics — magnetohydrodynamics.
- magnetoplasmadynamics — magnetohydrodynamics.

- mask read-only memory — (storage) (MROM) A kind of ROM in which the memory contents are determined by one of the masks used to manufacture the integrated circuit. MROM can give high storage density (bits per millimeter squared) making it a cheap solution for high volume applications.
- mauna kea observatory — an astronomical observatory on Mauna Kea, Hawaii, situated at an altitude of 13,600 feet (4145 meters).
- mean time to recovery — (specification) (MTTR) The average time that a device will take to recover from a non-terminal failure. Examples of such devices range from self-resetting fuses (where the MTTR would be very short, probably seconds), up to whole systems which have to be replaced. The MTTR would usually be part of a maintenance contract, where the user would pay more for a system whose MTTR was 24 hours, than for one of, say, 7 days. This means the supplier is guaranteeing to have the system up and running again within 24 hours (or 7 days) of being notified of the failure. Some devices have a MTTR of zero, which means that they have redundant components which can take over the instant the primary one fails, see RAID for example. See also Mean Time Between Failures.
- mechanical metallurgy — the branch of metallurgy dealing with the response of metals to applied forces.
- mechanical solidarity — social cohesiveness that is based on shared activities, beliefs, and experiences and is characteristic of simple traditional societies.

- multilayer perceptron — A network composed of more than one layer of neurons, with some or all of the outputs of each layer connected to one or more of the inputs of another layer. The first layer is called the input layer, the last one is the output layer, and in between there may be one or more hidden layers.
- munchausen's syndrome — a mental disorder in which a patient feigns illness to obtain hospital treatment
- muon-catalysed fusion — an experimental form of nuclear fusion in which hydrogen and deuterium muonic atoms are formed. Because the mass of the muon is much larger than that of the electron, the atoms are smaller, and the nuclei are close enough for fusion to occur
- myocardial infarction — heart attack. Abbreviation: MI.
