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.

Who You Are (Jessie J album)

Who You Are is the debut studio album by English singer-songwriter Jessie J, released on 28 February 2011. Due to high demand and interest from fans, the release advanced by a month from 28 March, as previously planned. Production for the album took place throughout 2010 and contributing producers included: Dr. Luke, Toby Gad and K-Gee.

Who You Are received generally mixed reviews from contemporary music critics. It débuted at number two on the UK Albums Chart selling 105,000 copies in its first week. The album débuted in the US at number 11 on the Billboard 200 with first-week sales of 34,000 copies. Two singles preceded the album: Jessie J's UK début single "Do It Like a Dude" and "Price Tag", featuring B.o.B which served as the US lead single. A third single, "Nobody's Perfect", became J's third consecutive top 10 hit in the UK. The fourth single from the album "Who's Laughing Now", released 21 August 2011, peaked at #16 on the UK Singles Chart. The title track, "Who You Are", was released on 13 November 2011 as the album's fifth UK single.

Skip (container)

A skip (UK English) or dumpster (US and Canadian English) is a large open-topped waste container designed for loading onto a special type of lorry. Instead of being emptied into a garbage truck on site, as a wheelie bin is, a skip is removed, or replaced by an empty skip, and then tipped at a landfill site or transfer station.

Typically skip bins have a distinctive shape: the longitudinal cross-section of the skip bin is either a trapezoid or two stacked trapezoids. The lower trapezoid has the smaller edge at the bottom of the skip bin, and a longer edge at the top. Where there is an upper trapezoid, it has the smaller edge at the top. At either end of the skip bin there is a sloping floor or wall. There are usually two lugs at the ends of the bin onto which chains can be attached, permitting the heavy skip bin to be lifted onto and off a lorry. A special skip-carrying lorry or crane is used.

One end of the skip sometimes has a large door that hinges down to allow manual loading and unloading. Skips are usually durable and tough, made to withstand rough use by tradesmen and labourers. The size of skip bins can vary greatly depending on their use, with sizes ranging from small 2 yard mini skips to the very large 40 yard roll-on roll-off skips. Even though these large bins can store many tonnes of waste, most lorries are limited to carrying around 8 tonnes (8,000 kg) of material in the container.

Gait (human)

Human gait refers to locomotion achieved through the movement of human limbs. Human gait is defined as bipedal, biphasic forward propulsion of center of gravity of the human body, in which there are alternate sinuous movements of different segments of the body with least expenditure of energy. Different gait patterns are characterized by differences in limb movement patterns, overall velocity, forces, kinetic and potential energy cycles, and changes in the contact with the surface (ground, floor, etc.). Human gaits are the various ways in which a human can move, either naturally or as a result of specialized training.

Classification

Gaits can be roughly categorized into two groups: the natural gaits that nearly every human will use without special training, and the specialized gaits which people train to use under specific conditions and situations.

Another classification system applicable to humans groups gaits by whether or not the person is continuously in contact with the ground.

List of minor Angel characters

This article features minor fictional characters who appear as guest stars on the cult television program Angel, ordered alphabetically. For the show's main characters, please see the article list of Angel characters.

A

Alonna Gunn

Alonna Gunn (played by Michele Kelly) was the sister of Charles Gunn, and the most important person in his life. The siblings took care of each other while growing up in the "Badlands" (a fictional neighborhood in Los Angeles). Alonna was turned into a vampire in her first appearance ("War Zone"). Gunn eventually found Alonna as a vampire and confronted her, but was ultimately forced to stake her with Angel looking on. Alonna continued to appear in future episodes in Gunn's memory, flashbacks, and dreams. She was also mentioned in many episodes including "That Old Gang of Mine". It was the death of Alonna that made Gunn receptive to Angel's help and also caused him to drift away from his old crew, as he was tired of seeing his friends "picked off one by one".
