Cascade (juggling)

In toss juggling, a cascade is the simplest juggling pattern achievable with an odd number of props. The simplest juggling pattern is the three-ball cascade. This is therefore the first pattern that most jugglers learn. "Balls or other props follow a horizontal figure-eight pattern above the hands." In siteswap, each throw in a cascade is notated using the number of balls; thus a three ball cascade is "3".

Number of props

Three-ball

For the three-ball cascade the juggler starts with two balls in one hand and the third ball in the other hand. One ball is thrown from the first hand in an arc to the other hand. Before catching this ball the juggler must throw the ball in the receiving hand, in a similar arc, to the first hand. The pattern continues in this manner with each hand in turn throwing one ball and catching another.

All balls are caught on the outside of the pattern (on the far left and right) and thrown from closer to the middle of the pattern. The hand moves toward the middle to throw, and back towards the outside to catch the next object. Because the hands must move up and down when throwing and catching, putting this movement together causes the left hand to move in a counterclockwise motion, and the right hand to move in a clockwise motion.

Professional wrestling attacks

Attacking maneuvers are offensive moves in professional wrestling, used to set up an opponent for a submission hold or for a throw. There are a wide variety of attacking moves in pro wrestling, and many are known by several different names. Professional wrestlers frequently give their finishers new names. Occasionally, these names become popular and are used regardless of the wrestler performing the technique.

Professional wrestling contains a variety of punches and kicks found in martial arts and other fighting sports; the moves listed below are more specific to wrestling itself. Many of the moves below can also be performed from a raised platform (the top rope, the ring apron, etc.); these are called aerial variations. Moves are listed under general categories whenever possible.

Bell clap

The wrestler slaps both ears of an opponent simultaneously with the palms of his hands, distorting their balance. It is often used to escape a bear hug.

Body press

Also known as a splash, a body press involves a wrestler falling against the opponent with the core of their body. It is executed from a running or jumping position, using momentum and weight to impact the opponent, and most variations can seamlessly transition into a pin. This attack is a plancha in lucha libre.

Chop (furniture)

A chop is a signature or identifying mark made by a furniture or cabinet maker to identify his work. In the 18th and 19th centuries, cabinet makers (sic) furniture makers were allowed to use their own individual chop to identify their work only when they had qualified as a Master Cabinetmaker. This practice originated from the Chinese tradition of seals called "chops" and was introduced to Europe in the middle ages. A chop was normally created by a mallet and chisel, creating a unique design. In some cases, fathers would pass the chop to their sons, and the son would then add a slight modification to indicate which generation created the piece.

The act of striking the chisel with the mallet or chopping is the root of the term.

Top

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.

Characteristics

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.

Top (mathematics)

In the context of a module M over a ring R, the top of M is the largest semisimple quotient module of M if it exists.

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.

Top (clothing)

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.

Design

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.
