Tide

Tides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon, Sun, and rotation of the Earth.

The times and amplitude of tides at a locale are influenced by the alignment of the Sun and Moon, by the pattern of tides in the deep ocean, by the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see Timing). Some shorelines experience a semi-diurnal tide - two nearly equal high and low tides each day. Other locations experience a diurnal tide - only one high and low tide each day. A "mixed tide"; two uneven tides a day, or one high and one low, is also possible.

Tides vary on timescales ranging from hours to years due to a number of factors. To make accurate records, tide gauges at fixed stations measure the water level over time. Gauges ignore variations caused by waves with periods shorter than minutes. These data are compared to the reference (or datum) level usually called mean sea level.

Tidal (livecoding)

Tidal is a live coding environment designed for musical improvisation. In particular, it is a domain-specific language embedded in Haskell, focused on the generation and manipulation of audible or visual patterns. It was originally designed for heavily percussive, polyrhythmic grid-based music, but now uses a flexible, functional reactive representation for patterns, using rational time. Tidal may therefore be applied to a wide range of musical styles, although its cyclic approach to time means that it affords use in repetitive styles such as Algorave.

In its native configuration, Tidal triggers samples on disk via a C-language sampler called Dirt . However there also exist integrations for MIDI, and for the SuperCollider sound environment.

Dimension

In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on it – for example, the point at 5 on a number line. A surface such as a plane or the surface of a cylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it – for example, both a latitude and longitude are required to locate a point on the surface of a sphere. The inside of a cube, a cylinder or a sphere is three-dimensional because three coordinates are needed to locate a point within these spaces.

In classical mechanics, space and time are different categories and refer to absolute space and time. That conception of the world is a four-dimensional space but not the one that was found necessary to describe electromagnetism. The four dimensions of spacetime consist of events that are not absolutely defined spatially and temporally, but rather are known relative to the motion of an observer. Minkowski space first approximates the universe without gravity; the pseudo-Riemannian manifolds of general relativity describe spacetime with matter and gravity. Ten dimensions are used to describe string theory, and the state-space of quantum mechanics is an infinite-dimensional function space.

Dimensions (film)

Dimensions is a 2011 science fiction-love story film set in the 1920s and 1930s. The film was directed by Sloane U’Ren and written by Ant Neely, who are a married couple. The film is U’Ren’s feature film directorial debut and is also known as Dimensions: A Line, A Loop, A Tangle of Threads.

Dimensions premiered as part of the 2011 Cambridge Film Festival (U.K.) and outsold, per screen, the U.K. premieres of Tinker Tailor Soldier Spy, The Help and Midnight in Paris. After the Cambridge screenings, the film underwent a minor re-edit and was finished in early 2012. Dimensions was voted Best Film 2012 at the 37th Boston Science Fiction Film Festival and awarded the Gort Award. Previous Gort Award winners have included Duncan Jones' Moon. The film went on to win Best Film at the London Independent Film Festival and Best Film at the Long Island International Film Expo. Director Sloane U'Ren was also awarded Best Director at the Long Island International Film Expo.

Plot

The film follows Stephen, a brilliant young scientist who lives in Cambridge, England, in what appears to be the 1920s. His world is turned upside down upon meeting a charismatic and inspirational professor at a garden party, who demonstrates to Stephen and his friends what life would be like if they were one-, or two-dimensional beings. He then proceeds to explain that by manipulating other dimensions, time travel may actually be possible.

Dimensions (Wolfmother)

Dimensions is the second extended play (EP) by Australian rock band Wolfmother, released on 31 January 2006. It includes a total of four tracks and two music videos; three of the four songs were previously released on the band's self-titled album (one, "Love Train", only on the international version).

Track listing

All songs were written by Andrew Stockdale, Chris Ross and Myles Heskett.
