  • infiltration gallery — a conduit, built in permeable earth, for collecting ground water.
  • infrared photography — photography using film with an emulsion that is sensitive to infrared light, enabling it to be used in misty weather, in darkened interiors, or at night. It has applications in aerial surveys, the detection of forgeries, etc
  • integration by parts — Mathematics. a method of evaluating an integral by use of the formula, ∫udv = uv − ∫vdu.
  • integrity constraint — (database)   A constraint (rule) that must remain true for a database to preserve data integrity. Integrity constraints are specified at database creation time and enforced by the database management system. Examples from a genealogical database would be that every individual must be their parent's child or that they can have no more than two natural parents.

  • magical mystery tour — something exciting and mysterious; esp an exploration of a new place where somebody being shown or taken around does not know where exactly they will be going
  • magnetohydrodynamics — the branch of physics that deals with the motion of electrically conductive fluids, especially plasmas, in magnetic fields. Abbreviation: MHD.
  • marginal probability — (in a multivariate distribution) the probability of one variable taking a specific value irrespective of the values of the others
  • mass-energy equation — the equation, E=mc2, formulated by Albert Einstein, expressing the equivalence between mass and energy, where E is energy, m is mass, and c is the velocity of light.
  • megabytes per second — (unit)   (MBps, MB/s) Millions of bytes per second. A unit of data rate. 1 MB/s = 1,000,000 bytes per second (not 1,048,576).
  • megakaryocytopoiesis — (biology) The cellular development process that leads to platelet production.
  • mickey mouse program — (jargon)   The North American equivalent of a "noddy program", i.e. trivial. The term doesn't necessarily have the belittling connotations of mainstream slang "Oh, that's just mickey mouse stuff!"; sometimes trivial programs can be very useful.
  • molecular gastronomy — an approach to cooking in which a chef’s knowledge of physics, chemistry, and biology allows him or her to experiment with unusual flavour combinations and cooking techniques
  • morning glory family — the plant family Convulvulaceae, characterized by twining herbaceous vines, shrubs, and trees having alternate, simple, or compound leaves, funnel-shaped, often showy flowers, and fruit in the form of a berry or capsule, and including bindweed, dodder, moonflower, morning glory, and sweet potato.
  • mpeg-1 audio layer 1 — (audio, compression, algorithm)   (MP1) A simple 32-subband audio compressor using a floating point representation for subband samples. Resolution and scale factor are stored for groups of 12 subsamples. MP1 is only used for Philips DCC Digital Compact cassette with data rates of 384 kbps.
  • mpeg-1 audio layer 3 — (music, file format)   (MP3) A digital audio compression algorithm that acheives a compression factor of about twelve while preserving sound quality. It does this by optimising the compression according to the range of sound that people can actually hear. MP3 is currently (July 1999) the most powerful algorithm in a series of audio encoding standards developed under the sponsorship of the Moving Picture Experts Group (MPEG) and formalised by the International Organization for Standardization (ISO). MP3 is very different from Layer 2, using an additional MDCT layer to increase frequency resolution. Its scale factor groups are more optimised for the human ear, and it uses nonlinear sample quantisation and Huffman coding. MP3 files (filename extension ".mp3") can be downloaded from many websites and can be played using software available for most operating systems (also downloadable), e.g. Winamp for PC, MacAmp for Macintosh, and mpeg123 for Unix. MP3 files are usually downloaded completely before playing but streaming MP3 is also possible. A program called a "ripper" can be used to copy a selection from a music CD onto your hard disk and another program called an encoder can convert it to an MP3 file.
  • mpeg-2 audio layer 3 — (compression, standard, algorithm, file format)   An extention of MPEG-1 audio layer 3 for lower sampling rates (16-24 kHz) targeting bit rates from 32-64 kbps (possibly 8-160 kbps). It is often combined with MPEG-2 LSF.

  • pay through the nose — the part of the face or facial region in humans and certain animals that contains the nostrils and the organs of smell and functions as the usual passageway for air in respiration: in humans it is a prominence in the center of the face formed of bone and cartilage, serving also to modify or modulate the voice.

  • pythagoras's theorem — (mathematics)   The theorem of geometry, named after Pythagoras, of Samos, Ionia, stating that, for a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. I.e. if the longest side has length A and the other sides have lengths B and C (in any units), A^2 = B^2 + C^2 (2004-02-12)
