- lateral magnification — the ratio of the height of the image to the height of the object in a lens or other optical system.
- 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)
- line of communication — a means by which information may be transmitted from one person to another
- linear transformation — linear map

- 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.
- magnetocaloric effect — an increase or decrease of the temperature of a thermally isolated magnetic substance accompanying an increase or decrease in the intensity of a magnetic field.

- network filing system — (spelling) Misnomer for Network File System.
- nine times out of ten — If you say that something happens or is the case nine times out of ten or ninety-nine times out of a hundred, you mean that it happens on nearly every occasion or is almost always the case.
