Rainbow
A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.
Rainbows can be full circles; however, the average observer sees only an arc formed by illuminated droplets above the ground, and centred on a line from the sun to the observer's eye.
In a primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.
In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, with red on the inner side of the arc.
Overview
A rainbow is not located at a specific distance from the observer, but comes from an optical illusion caused by any water droplets viewed from a certain angle relative to a light source. Thus, a rainbow is not an object and cannot be physically approached. Indeed, it is impossible for an observer to see a rainbow from water droplets at any angle other than the customary one of 42 degrees from the direction opposite the light source. Even if an observer sees another observer who seems "under" or "at the end of" a rainbow, the second observer will see a different rainbow—farther off—at the same angle as seen by the first observer.

Clean (programming language)
In computer science, Clean is a general-purpose purely functional computer programming language. For much of the language's active development history it was called Concurrent Clean and emphasized concurrency, but this was dropped at some point.
Features
The language Clean first appeared in 1987 and is still being further developed. It shares many properties with Haskell: referential transparency, list comprehension, guards, garbage collection, higher order functions, currying and lazy evaluation.
An integrated development environment (IDE) is included in the Clean distribution.
Clean's method for dealing with mutable state and I/O is done through a uniqueness typing system, in contrast to Haskell's use of monads. The compiler takes advantage of the uniqueness type system to generate more efficient code, because it knows that anything with a uniqueness type can only be used once. Therefore, a unique value can be changed in place.
Examples
The Clean
The Clean are an indie rock band that formed in Dunedin, New Zealand in 1978, and have been described as the most influential band to come from the Flying Nun label, whose repertoire included many major components of the "Dunedin Sound". Led through a number of early rotating line-ups by brothers Hamish and David Kilgour, the band settled down to their well-known and current line-up with bassist Robert Scott.
History
Hamish and David Kilgour started to play and write music together in Dunedin in 1978, "building up a fat songbook of primitive punk, minimalist pop, infectious folk rock and adventurous psychedelic instrumentals. Their sound was built around David Kilgour’s off-centre, 1960s-influenced guitar, Hamish’s motorik drumming and melodic driving bass, first from Peter Gutteridge then Robert Scott".
The band's 1981 debut single "Tally Ho!" was the second release on Roger Shepherd's Flying Nun Records label. "Tally Ho!" reached number 19 on the New Zealand Singles Charts, giving the fledgling label its first hit.
