  • 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
  • lull before the storm — If you describe a situation as the lull before the storm, you mean that although it is calm now, there is going to be trouble in the future.
  • luminous flux density — luminous flux per unit of cross-sectional area.
  • 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.
  • 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.
  • magnetofluid dynamics — magnetohydrodynamics.

  • mother-of-pearl cloud — nacreous cloud.
  • mother-of-pearl glass — an American art glassware having colored glass set into indentations in a thickness of opaque glass, the whole covered with clear glass and etched slightly with acid.
  • 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
  • network filing system — (spelling)   Misnomer for Network File System.
  • nightmare file system — Pejorative hackerism for Sun's Network File System (NFS). In any nontrivial network of Suns where there is a lot of NFS cross-mounting, when one Sun goes down, the others often freeze up. Some machine tries to access the down one, and (getting no response) repeats indefinitely. This causes it to appear dead to some messages (what is actually happening is that it is locked up in what should have been a brief excursion to a higher spl level). Then another machine tries to reach either the down machine or the pseudo-down machine, and itself becomes pseudo-down. The first machine to discover the down one is now trying both to access the down one and to respond to the pseudo-down one, so it is even harder to reach. This situation snowballs very quickly, and soon the entire network of machines is frozen - worst of all, the user can't even abort the file access that started the problem! Many of NFS's problems are excused by partisans as being an inevitable result of its statelessness, which is held to be a great feature (critics, of course, call it a great misfeature). ITS partisans are apt to cite this as proof of Unix's alleged bogosity; ITS had a working NFS-like shared file system with none of these problems in the early 1970s. See also broadcast storm.
