** An oscillating member where this clutch can then convert the oscillations into intermittent linear or rotational motion of the complimentary member ; others use ratchets with the pawl mounted on a moving member

* Dynamics ( mechanics ), ** Aerodynamics, the study of gases in motion

** Analytical dynamics, the motion of bodies as induced by external forces

** Anomalous dynamics ( Random walk # Anomalous diffusion ), the stochastic motion of objects with mean squared displacement ( MSD ) that deviates from the relation for normal dynamics, MSD ~ t, where t is the time the process is seen ; anomalous dynamics are either faster than normal dynamics ( MSD > t ) or slower ( MSD < t )

** Brownian dynamics, the occurrence of Langevin dynamics in the motion of particles in solution ( e. g. a grain in water, as was first seen by Brown ); its famous property is: MSD ~ t, where MSD is the mean squared displacement, and t is the time the process is seen

** File dynamics, stochastic motion of particles in a channel

** Molecular dynamics, the study of motion on the molecular level

** Normal dynamics, is a stochastic motion having a Gaussian probability density function in position with variance MSD that follows, MSD ~ t, where MSD is the mean squared displacement of the process, and t is the time the process is seen ( normal dynamics and Brownian dynamics are very similar ; the term used depends on the field )

** Stellar dynamics, a description of the collective motion of stars

** Hysteresis: Changing or reversing the magnetic field in the core also causes losses due to the motion of the tiny magnetic domains it is composed of.

** Rigid body kinetics, the study of the motion of rigid bodies

** Newton's laws of motion

** 3D rendering, generating image or motion picture from virtual 3D models

** The celestial region was made up of the fifth element, Aether, which was unchanging and moved naturally with uniform circular motion.

** Walt Disney releases his 18th feature-length animated motion picture The Sword in the Stone, about the boyhood of King Arthur.

** Frank J. Marion, American motion picture pioneer ( b. 1869 )

** Louis Le Prince films the first motion picture: Roundhay Garden Scene in Roundhay, Leeds, West Yorkshire, UK ( followed by his movie Leeds Bridge ).

** In Britain, Jim Callaghan's minority Labour government loses a motion of confidence by 1 vote, forcing a general election which is to be held on 3 May.

** Results of the Michelson-Morley experiment are published, indicating that the speed of light is independent of motion.

** Willis O ' Brien, American stop motion animator ( d. 1962 )

** The Hays Office censorship code for motion pictures goes into full effect in the United States.

** Cinéfondation – About fifteen shorts and medium-length motion pictures from film schools over the world are presented at the Salle Buñuel.

** Drag ( physics ) (" air resistance "), fluid or gas forces opposing motion and flow

** Newton's laws of motion

** City buses ( see picture below ):

** Physically attaching a picture or a painting on to a support followed by framing with a picture frame.

** Souvenir sheets – many postal services sometimes release stamps in a format that look like a sheet with a big picture.

** The Morgan Bible, a French medieval picture Bible

** QuarkXPress 6. 5 ( 2004 )-First version to also support the Document Object Model and picture retouching features.

** In Porky in Wackyland, Porky shows a picture of the dodo in his airplane, after the newspaper is shown.

** Hockney's Choclo: 10 variations, imitations and paraphrases on Piazzolla's arrangement of the tango ' El Choclo ' after a picture by David Hockney for accordion, piano, violin, electric guitar and bass ( 2003 )

** Earlier generation displays were more susceptible to screen burn-in and image retention, recent models have a pixel orbiter that moves the entire picture slower than is noticeable to the human eye, which reduces the effect of burn-in but does not prevent it.

** It can also be seen in " The Burns and The Bees " when Mr. Burns ' shoots an arrow at the picture in the " Billions Club ".

** Macroblock-adaptive frame-field ( MBAFF ) coding, using a macroblock pair structure for pictures coded as frames, allowing 16 × 16 macroblocks in field mode ( compared with MPEG-2, where field mode processing in a picture that is coded as a frame results in the processing of 16 × 8 half-macroblocks ).

** Redundant slices ( RS ), an error / loss robustness feature allowing an encoder to send an extra representation of a picture region ( typically at lower fidelity ) that can be used if the primary representation is corrupted or lost.

** Before My Fair Lady began its six-year, 2717 performance run at the Mark Hellinger Theatre in 1956, that theatre was thought to be cursed., It had been switched back and forth several times between being a motion picture theatre and a live stage theatre.

** Marvel Studios a motion picture studio based in Beverly Hills, California

** black and white picture sleeve, Spanish titles on the label and the cover ( EMI P-040 )

** Landsat picture of Washington, D. C.
