A top is a toy designed to be spun rapidly on the ground, the motion of which causes it to remain precisely balanced on its tip because of inertia. Such toys have existed since antiquity. Traditionally tops were constructed of wood, sometimes with an iron tip, and would be set in motion by aid of a string or rope coiled around its axis which, when pulled quickly, caused a rapid unwinding that would set the top in motion. Today they are often built of plastic, and modern materials and manufacturing processes allow tops to be constructed with such precise balance that they can be set in motion by a simple twist of the fingers and twirl of the wrist without need for string or rope.
The motion of a top is produced in the most simple forms by twirling the stem using the fingers. More sophisticated tops are spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger. In the kinds with an auger, an internal weight rotates, producing an overall circular motion. Some tops can be thrown, while firmly grasping a string that had been tightly wound around the stem, and the centrifugal force generated by the unwinding motion of the string will set them spinning upon touching ground.
For finite-dimensional k-algebras (k a field), if rad(M) denotes the intersection of all proper maximal submodules of M (the radical of the module), then the top of M is M/rad(M). In the case of local rings with maximal ideal P, the top of M is M/PM. In general if R is a semilocal ring (=semi-artinian ring), that is, if R/Rad(R) is an Artinian ring, where Rad(R) is the Jacobson radical of R, then M/rad(M) is a semisimple module and is the top of M. This includes the cases of local rings and finite dimensional algebras over fields.
A top is clothing that covers at least the chest, but which usually covers most of the upper human body between the neck and the waistline. The bottom of tops can be as short as mid-torso, or as long as mid-thigh. Men's tops are generally paired with pants, and women's with pants or skirts. Common types of tops are t-shirts, blouses and shirts.
The neckline is the highest line of the top, and may be as high as a head-covering hood, or as low as the waistline or bottom hem of the top. A top may be worn loose or tight around the bust or waist, and may have sleeves or shoulder straps, spaghetti straps (noodle straps), or may be strapless. The back may be covered or bare. Tops may have straps around the waist or neck, or over the shoulders.
Rastafari is an Abrahamic belief which developed in Jamaica in the 1930s, following the coronation of Haile Selassie I as Emperor of Ethiopia in 1930. Its adherents worship him in much the same way as Jesus in his Second Advent, or as God the Father. Members of the Rastafari way of life are known as Rastafari, Rastas, Rastafarians, or simply Ras. Rastafari are also known by their official church titles, such as Elder or High Priest. The way of life is sometimes referred to as "Rastafarianism", but this term is considered offensive by most Rastafari, who, being critical of "isms" (which they see as a typical part of "Babylon" culture), dislike being labelled as an "ism" themselves.
The name Rastafari is taken from Ras Tafari, the title (Ras) and first name (Tafari Makonnen) of Haile Selassie I before his coronation. In Amharic, Ras, literally "head", is an Ethiopian title equivalent to prince or chief, while the personal given name Täfäri (teferi) means one who is revered. Jah (יה in Hebrew) is a Biblical name of God, from a shortened form of Jahweh or Jehovah found in Psalms 68:4 in the King James Version of the Bible and many other places in the Bible. Most adherents see Haile Selassie I as Jah or Jah Rastafari, an incarnation of God the Father, the Second Advent of Christ "the Anointed One", i.e. the second coming of Jesus Christ the King to Earth.
"Every Mandaean must own a simple white ceremonial garment, called a rasta. It must be worn during most baptismal rites, religious ceremonies, and during periods of uncleanliness. It signifies the purity of the world of light. The rasta is worn equally by the laypersons and the priests. If a Mandaean dies in clothes other than a rasta, it is believed that they will not reenter the "World of Light"," unless the rite "Ahaba d Mania" ('Giving of Garments') be performed "for those who have died not wearing the ritual garment."
The rasta is expected to be transmuted after death into a "garment of glory" for the soul ("the Perfecter of Souls ... will come out toward you and clothe your soul in a garment of radiance") – this is equivalent to the perispirit.
A Mandaic hymn states:
"I became a garment to the worlds of Light ...
As for the chosen righteous, who put me on (as a garment),
their eyes were filled with Light."
