Kuttiyum Kolum
Kuttiyum kolum ( en, stick and cane) is a traditional game played in Kerala, India. It is similar to an ancient game found all over the Indian Subcontinent with different names, such as Gilli-danda in North India. A similar game by the name of :it:Lippa (gioco), Lippa has been played in Italy. Kuttiyum kolum possibly originated over 2500 years ago.John Arlott (1975), The Oxford Companion to World Sports and Games, Oxford University Press, Rules The objective of the sport is to use the kolu like a baseball bat to strike the kutti (similar to striking a ball in cricket or baseball). For this purpose, a circle is drawn in the ground in which a small, oblong- or spindle-shaped hole is dug (in the shape of a traditional boat). This hole is smaller than the kutti but as the play progresses the size may increase due to wear. The kutti is inserted into the hole either Orthogonality, orthogonally, or at an angle. The danda is then swung (similar to a Golf Swing#The golf swing, golf sw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerala
Kerala ( ; ) is a state on the Malabar Coast of India. It was formed on 1 November 1956, following the passage of the States Reorganisation Act, by combining Malayalam-speaking regions of the erstwhile regions of Cochin, Malabar, South Canara, and Thiruvithamkoor. Spread over , Kerala is the 21st largest Indian state by area. It is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Lakshadweep Sea to the west. With 33 million inhabitants as per the 2011 census, Kerala is the 13th-largest Indian state by population. It is divided into 14 districts with the capital being Thiruvananthapuram. Malayalam is the most widely spoken language and is also the official language of the state. The Chera dynasty was the first prominent kingdom based in Kerala. The Ay kingdom in the deep south and the Ezhimala kingdom in the north formed the other kingdoms in the early years of the Common Era (CE). The region had been a prominent spic ...

India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ...

Gilli-danda
Gilli Danda (also spelled Gulli-Danda) also known as Viti Dandu, Kitti-Pul and by other variations, is a sport Traditional games of India, originating from the Indian subcontinent, played in the rural areas and small towns all over South Asia as well as Cambodia, Iran, Turkey, South Africa, Italy, Poland, and in some Caribbean islands like CubThe game is played with two sticks: a large one called a ''danda (Dandi in Nepali, Dandu/दांडू/ದಾಂಡು in Marathi, Kittipul/கிட்டிப்புள் in Tamil and Kannada, കോൽ in Malayalam)'', which is used to hit a smaller one, the ''gilli (Biyo in Nepali, Viti/विटी in Marathi, kittikol/ கிட்டிக்கோல் in Tamil and Chinni/ಚಿನ್ನಿ in Kannada, കുറ്റി in Malayalam)''. Other than using a smaller target stick, rather than a ball, it bears many similarities to bat and ball games such as cricket and baseball. Gullidanda is an ancient sport, possibly with ...

Baseball Bat
A baseball bat is a smooth wooden or metal club used in the sport of baseball to hit the ball after it is thrown by the pitcher. By regulation it may be no more than in diameter at the thickest part and no more than in length. Although historically bats approaching were swung, today bats of are common, topping out at to . Terminology A baseball bat is divided into several regions. The "barrel" is the thick part of the bat, where it is meant to hit the ball. The part of the barrel best for hitting the ball, according to construction and swinging style, is often called the " sweet spot." The end of the barrel is called the "top," "end," or "cap" of the bat. Opposite the cap, the barrel narrows until it meets the "handle," which is comparatively thin, so that batters can comfortably grip the bat in their hands. Sometimes, especially on metal bats, the handle is wrapped with a rubber or tape "grip". Finally, below the handle is the "knob" of the bat, a wider piece that keeps t ...

Ball
A ball is a round object (usually spherical, but can sometimes be ovoid) with several uses. It is used in ball games, where the play of the game follows the state of the ball as it is hit, kicked or thrown by players. Balls can also be used for simpler activities, such as catch or juggling. Balls made from hard-wearing materials are used in engineering applications to provide very low friction bearings, known as ball bearings. Black-powder weapons use stone and metal balls as projectiles. Although many types of balls are today made from rubber, this form was unknown outside the Americas until after the voyages of Columbus. The Spanish were the first Europeans to see the bouncing rubber balls (although solid and not inflated) which were employed most notably in the Mesoamerican ballgame. Balls used in various sports in other parts of the world prior to Columbus were made from other materials such as animal bladders or skins, stuffed with various materials. As balls are one o ...

Baseball
Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play generally beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a bat. The objective of the offensive team (batting team) is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called " runs". The objective of the defensive team (referred to as the fielding team) is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter). The principal objective of the batting team is to have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthogonality
In mathematics, orthogonality is the generalization of the geometric notion of ''perpendicularity''. By extension, orthogonality is also used to refer to the separation of specific features of a system. The term also has specialized meanings in other fields including art and chemistry. Etymology The word comes from the Ancient Greek ('), meaning "upright", and ('), meaning "angle". The Ancient Greek (') and Classical Latin ' originally denoted a rectangle. Later, they came to mean a right triangle. In the 12th century, the post-classical Latin word ''orthogonalis'' came to mean a right angle or something related to a right angle. Mathematics Physics * In optics, polarization states are said to be orthogonal when they propagate independently of each other, as in vertical and horizontal linear polarization or right- and left-handed circular polarization. * In special relativity, a time axis determined by a rapidity of motion is hyperbolic-orthogonal to a space axis of simu ...

Angle
In Euclidean geometry, an angle is the figure formed by two Ray (geometry), rays, called the ''Side (plane geometry), sides'' of the angle, sharing a common endpoint, called the ''vertex (geometry), vertex'' of the angle. Angles formed by two rays lie in the plane (geometry), plane that contains the rays. Angles are also formed by the intersection of two planes. These are called dihedral angles. Two intersecting curves may also define an angle, which is the angle of the rays lying tangent to the respective curves at their point of intersection. ''Angle'' is also used to designate the measurement, measure of an angle or of a Rotation (mathematics), rotation. This measure is the ratio of the length of a arc (geometry), circular arc to its radius. In the case of a geometric angle, the arc is centered at the vertex and delimited by the sides. In the case of a rotation, the arc is centered at the center of the rotation and delimited by any other point and its image by the rotation ...

Golf Swing
The golf swing is the action by which players hit the ball in the sport of golf. The golf swing is a complex motion involving the whole body; the technicalities of the swing are known as golf stroke mechanics. There are differing opinions on what constitutes a "good" golf swing. In ''Work and Power Analysis of the Golf Swing'', Nesbit and Serrano suggest the golf swing has been studied by scientists and mathematicians who have developed various equations to help explain the complexity of the swing. It is generally agreed that a successful and consistent golf swing requires precise timing and mechanics, from the grip and position of one's fingers, to the position and movement of the feet. At any moment of the swing, whether back-swing, downswing, or upswing, something can go wrong that will throw off the whole body and result in a mishit. The entire swing motion should move on a plane in a fluid manner. The plane can be characterized as horizontal or vertical. Complex motion The g ...
