Gravity or gravitation is a natural phenomenon by which all things with energy are brought toward (or gravitate toward) one another, including stars, planets, galaxies and even light and sub-atomic particles. Gravity is responsible for many of the structures in the Universe, by creating spheres of hydrogen — where hydrogen fuses under pressure to form stars — and grouping them into galaxies. On Earth, gravity gives weight to physical objects and causes the tides. Gravity has an infinite range, although its effects become increasingly weaker on farther objects.
Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915) which describes gravity not as a force but as a consequence of the curvature of spacetime caused by the uneven distribution of mass/energy; and resulting in gravitational time dilation, where time lapses more slowly in lower (stronger) gravitational potential. However, for most applications, gravity is well approximated by Newton's law of universal gravitation, which postulates that gravity is a force where two bodies of mass are directly drawn (or 'attracted') to each other according to a mathematical relationship, where the attractive force is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is considered to occur over an infinite range, such that all bodies (with mass) in the universe are drawn to each other no matter how far they are apart.
Gravitation (Japanese: グラビテーション, Hepburn: Gurabitēshon) is a yaoi manga series written and illustrated by Maki Murakami. The story follows the attempts of Shuichi Shindo and his band, Bad Luck, to become Japan's next musical sensation, and his struggles to capture Eiri Yuki's heart.
The manga was published by Gentosha and was serialized on Kimi to Boku starting in 1996 and ending in 2002. The manga has been licensed and published in English by Tokyopop, as well as a light novel. There is also the Gravitation Collection which consists of 6 volumes, each of which has two original volumes of Gravitation in it. A sequel, Gravitation EX. (グラビテーションEX., Gurabitēshon EX.), was published in the web magazine Genzo from 2004 to 2009 and returned in 2011 to Web Spica.
Gravitation has also been adapted into a two episode OVA series in 1999 directed by Shinichi Watanabe and a thirteen-episode TV anime series directed by Bob Shirohata. The TV series aired in Japan from October 4, 2000 to January 10, 2001, on WOWOW Wednesdays at 18:30 and was reaired on Tokyo MX in 2007. The anime goes to roughly volume 7 of the manga. Both have been licensed for North American release by Nozomi Entertainment.
Gravitation (Serbo-Croatian: Gravitacija ili fanstastična mladost činovnika Borisa Horvata; English: The Fantastic Youth of Bank Clerk Boris Horvat) is a Yugoslav film from Croatia directed by Branko Ivanda and starring Rade Šerbedžija. It was released in 1968.
Jama or JAMA may refer to:
The term jama refers to a long coat which was popular in South Asia during the Mughal period.
Some styles of the jama were tight around the torso but flared out like a skirt to below the knees or the ankles. Other styles, such as the chakman jama, ended at around the knees. The sleeves tended to be full. The jama was fastened to either side with strings with some styles also opening at the front. What was originally male dress was also adopted by women who wore the jama with a scarf and tight fitting pajamas. The ties of the upper half of the jama are taken under the armpit and across the chest.
A particular style of jama was the pointed jama which was like the standard Mughal jama but the skirt fell in four to six points instead of the circular hem of the Mughal jama.This jama may be derived from the Rajput court's takauchiah and therefore could be of local origin. During the Sikh reign the jama was no longer flowing but shorter and often tucked up around the waist to allow freedom of movement. During the 19th and 20th centuries A.D. the jama was reduced to a shirt like garment in the northern (upper) parts of British India.
Jama is one of the woredas in the Amhara Region of Ethiopia. Part of the Debub Wollo Zone, Jama is bordered on the southeast by the Qechene River which separates it from the Semien Shewa Zone, on the west by Kelala, on the north by Legahida, and on the northeast by Were Ilu. Towns in Jama include Degolo and Shul Afaf.
Based on the 2007 national census conducted by the Central Statistical Agency of Ethiopia (CSA), this woreda has a total population of 126,879, an increase of 18.18% over the 1994 census, of whom 63,166 are men and 63,713 women; 6,048 or 4.77% are urban inhabitants. With an area of 1,051.93 square kilometers, Jama has a population density of 120.62, which is less than the Zone average of 147.58 persons per square kilometer. A total of 28,919 households were counted in this woreda, resulting in an average of 4.39 persons to a household, and 27,653 housing units. The majority of the inhabitants said they practiced Ethiopian Orthodox Christianity, with 54.69% reporting that as their religion, while 45.1% of the population were Muslim.
