A drum kit – also called a drum set, trap set or simply drums – is a collection of drums, cymbals and other percussion instruments, which are set up on stands to be played by a single player, with drumsticks held in both hands and the feet operating pedals that control the hi-hat cymbal and the beater for the bass drum. A drum kit consists of a mix of drums and idiophones – most significantly cymbals, but can also include the woodblock and cowbell. In the 2020s, some kits also include electronic instruments. Also, both hybrid and entirely electronic kits are used.
The eight queens puzzle is the problem of placing eight chess queens on an 8×8 chessboard so that no two queens threaten each other; thus, a solution requires that no two queens share the same row, column, or diagonal. There are 92 solutions. The problem was first posed in the mid-19th century. In the modern era, it is often used as an example problem for various computer programming techniques.
Matchstick puzzles are rearrangement puzzles in which a number of matchsticks are arranged as squares, rectangles or triangles. The problem to solve is usually formulated as: "move n matchsticks to make m squares, triangles, or rectangles". Some match stick problems are solved with planar topological graphs.
A burr puzzle is an interlocking puzzle consisting of notched sticks, combined to make one three-dimensional, usually symmetrical unit. These puzzles are traditionally made of wood, but versions made of plastic or metal can also be found. Quality burr puzzles are usually precision-made for easy sliding and accurate fitting of the pieces. In recent years the definition of "burr" is expanding, as puzzle designers use this name for puzzles not necessarily of stick-based pieces.
A pointing stick is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice, touchpads or trackballs, operating system software translates manipulation of the device into movements of the pointer or cursor on the monitor. Unlike other pointing devices, it reacts to sustained force or strain rather than to gross movement, so it is called an "isometric" pointing device. IBM introduced it commercially in 1992 on its laptops under the name "TrackPoint", patented in 1997.
A glow stick, also known as a light stick, chem light, light wand, light rod, and rave light, is a self-contained, short-term light-source. It consists of a translucent plastic tube containing isolated substances that, when combined, make light through chemiluminescence. The light cannot be turned off and can be used only once. The used tube is then thrown away. Glow sticks are often used for recreation, such as for events, camping, outdoor exploration, and concerts. Glow sticks are also relied upon for light during military, police, fire, and emergency medical services operations. Industrial uses include marine, transportation, and mining.
A hockey stick is a piece of sports equipment used by the players in all the forms of hockey to move the ball or puck either to push, pull, hit, strike, flick, steer, launch or stop the ball/puck during play with the objective being to move the ball/puck around the playing area using the stick, and then trying to score.
In geometry, the 5-cell is the regular convex 4-polytope (four-dimensional analogue of a Platonic solid) with Schläfli symbol {3,3,3}. It is a four-dimensional object bounded by 5 tetrahedral cells. It is also known as a C5, pentachoron, pentatope, pentahedroid, or tetrahedral pyramid. It is the 4-simplex (Coxeter's polytope), the simplest possible convex regular 4-polytope (four-dimensional analogue of a Platonic solid), and is analogous to the tetrahedron in three dimensions and the triangle in two dimensions. The pentachoron is a four dimensional pyramid with a tetrahedral base.
Icestock sport is a winter sport, somewhat similar to curling. In German, it is known as Eisstockschießen.
In recreational mathematics, a polystick is a polyform with a line segment as the basic shape. A polystick is a connected set of segments in a regular grid. A square polystick is a connected subset of a regular square grid. A triangular polystick is a connected subset of a regular triangular grid. Polysticks are classified according to how many line segments they contain.
An analog stick, sometimes called a control stick or thumbstick, is an input device for a controller that is used for two-dimensional input. An analog stick is a variation of a joystick, consisting of a protrusion from the controller; input is based on the position of this protrusion in relation to the default "center" position. While digital sticks rely on single electrical connections for movement, analog sticks use continuous electrical activity running through potentiometers to measure the exact position of the stick within its full range of motion. The analog stick has greatly overtaken the D-pad in both prominence and usage in console video games.
A tenor drum is a membranophone without a snare. There are several types of tenor drums.
In woodworking and carpentry, a pair of winding sticks is a tool that aids in viewing twist in pieces of lumber by amplifying the defect. Winding sticks can be as simple as any two straight sticks or they can be elegant, decorated, dimensionally stable wood like mahogany. A pair of framing squares may also be suitable. Traditionally they are 16 inches (41 cm) to 30 inches (76 cm) long, 1+3⁄4 inches (44 mm) tall and tapered in their height from 3⁄8 inch (9.5 mm) to 1⁄8 inch (3.2 mm). The longer the winding sticks, the more they will amplify the wind. It is common for a woodworker to make a matching pair for the purpose, and contrasting colors of woods improve the discernability of differences in height and level between the two sticks as they are compared.
A stick bomb is a (mechanical) spring-loaded device constructed out of flat sticks woven together under a bending moment. Other names for stick bombs include Chinese stick puzzles, Cobra wave, and frame bombs. Stick bombs are created for fun and as art, not for any practical use.
The throwing stick or throwing club is a wooden rod with either a pointed tip or a spearhead attached to one end, intended for use as a weapon. A throwing stick can be either straight or roughly boomerang-shaped, and is much shorter than the javelin. It became obsolete as slings and bows became more prevalent, except on the Australian continent, where the native people continued refining the basic design. Throwing sticks shaped like returning boomerangs are designed to fly straight to a target at long ranges, their surfaces acting as airfoils. When tuned correctly they do not exhibit curved flight, but rather they fly on an extended straight flight path. Straight flight ranges greater than 100 meters have been reported by historical sources as well as in recent research.
A lacrosse stick or crosse is used to play the sport of lacrosse. Players use the lacrosse stick to handle the ball and to strike or "check" opposing players' sticks, causing them to drop the ball. The head of a lacrosse stick is roughly triangular in shape and is strung with loose netting that allows the ball to be caught, carried, passed, or shot.
The Nintendo 64 controller is the standard game controller for the Nintendo 64 home video game console. Manufactured and released by Nintendo on June 23, 1996, in Japan, in late 1996 in North America, and 1997 in Europe, it is the successor to the Super Nintendo controller and is designed in an "M" shape and features 10 buttons, one analog "Control Stick" and a directional pad.
Casper: Spirit Dimensions is a 2001 action-adventure video game released by Lucky Chicken, based on the Harvey Comics cartoon character Casper the Friendly Ghost.
In field hockey, each player carries a stick and cannot take part in the game without it. The stick for an adult is usually in the range 89–95 cm (35–38 in) long. A maximum length of 105 cm (41.3") was stipulated from 2015. The maximum permitted weight is 737 grams. The majority of players use a stick in the range 19 oz to 22 oz. Traditionally hockey sticks were made of hickory, ash or mulberry wood with the head of the sticks being hand carved and therefore required skilled craftsmen to produce. Sticks made of wood continue to be made but the higher grade sticks are now manufactured from composite materials which were first permitted after 1992. These sticks usually contain a combination of fibreglass, aramid fiber and carbon fibre in varying proportions according to the characteristics required.
In chemistry, the ball-and-stick model is a molecular model of a chemical substance which is to display both the three-dimensional position of the atoms and the bonds between them. The atoms are typically represented by spheres, connected by rods which represent the bonds. Double and triple bonds are usually represented by two or three curved rods, respectively, or alternately by correctly positioned sticks for the sigma and pi bonds. In a good model, the angles between the rods should be the same as the angles between the bonds, and the distances between the centers of the spheres should be proportional to the distances between the corresponding atomic nuclei. The chemical element of each atom is often indicated by the sphere's color.
