Knuckleball (association Football)
A knuckleball or knuckler is a baseball pitch thrown to minimize the spin of the ball in flight, causing an erratic, unpredictable motion. The air flow over a seam of the ball causes the ball to change from laminar to turbulent flow. This change adds a deflecting force to the baseball, making it difficult for batters to hit but also difficult for pitchers to control and catchers to catch; umpires are challenged as well, as the ball's irregular motion through the air makes it harder to call balls and strikes.Hoffman, Benjamin"Not So Easy on the Eyes"''New York Times'' (June 23, 2012) A pitcher who throws knuckleballs is known as a knuckleballer. Origins The origins of the knuckleball are unclear. Toad Ramsey of the Louisville Colonels in the old American Association—his pitch likely resembled the knuckle curve—and Eddie Cicotte of the Chicago White Sox, who in 1908 was nicknamed "Knuckles", are two possible creators of the pitch. Other accounts attribute the pitch's creati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chicago White Sox
The Chicago White Sox are an American professional baseball team based in Chicago. The White Sox compete in Major League Baseball (MLB) as a member club of the American League (AL) Central division. The team is owned by Jerry Reinsdorf, and plays its home games at Guaranteed Rate Field, located on Chicago's South Side. The White Sox are one of two MLB teams based in Chicago, the other being the Chicago Cubs of the National League (NL) Central division. One of the American League's eight charter franchises, the White Sox were established as a major league baseball club in as the Chicago White Stockings, before shortening their name to the White Sox in . The team originally played their home games at South Side Park before moving to Comiskey Park in , where they played until . They moved into their current home, which was originally also known as Comiskey Park like its predecessor and later carried sponsorship from U.S. Cellular, for the 1991 season.

Drag (physics)
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trajectory
A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics, a trajectory is defined by Hamiltonian mechanics via canonical coordinates; hence, a complete trajectory is defined by position and momentum, simultaneously. The mass might be a projectile or a satellite. For example, it can be an orbit — the path of a planet, asteroid, or comet as it travels around a central mass. In control theory, a trajectory is a time-ordered set of states of a dynamical system (see e.g. Poincaré map). In discrete mathematics, a trajectory is a sequence (f^k(x))_ of values calculated by the iterated application of a mapping f to an element x of its source. Physics of trajectories A familiar example of a trajectory is the path of a projectile, such as a thrown ball or rock. In a significantly simplified model, the object moves only under the influence of a uniform gravitational force field. This can be ...

Cy Young Award
The Cy Young Award is given annually to the best pitchers in Major League Baseball (MLB), one each for the American League (AL) and National League (NL). The award was first introduced in 1956 by Baseball Commissioner Ford Frick in honor of Hall of Fame pitcher Cy Young, who died in 1955. The award was originally given to the single best pitcher in the major leagues, but in 1967, after the retirement of Frick, the award was given to one pitcher in each league. Each league's award is voted on by members of the Baseball Writers' Association of America, with one representative from each team. As of the 2010 season, each voter places a vote for first, second, third, fourth, and fifth place among the pitchers of each league. The formula used to calculate the final scores is a weighted sum of the votes. The pitcher with the highest score in each league wins the award. If two pitchers receive the same number of votes, the award is shared. From 1970 to 2009, writers voted for three pitche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fingernail
A nail is a claw-like plate found at the tip of the fingers and toes on most primates. Nails correspond to the claws found in other animals. Fingernails and toenails are made of a tough protective protein called alpha-keratin, which is a polymer. Alpha-keratin is found in the hooves, claws, and horns of vertebrates. Structure The nail consists of the nail plate, the nail matrix and the nail bed below it, and the grooves surrounding it. Parts of the nail The matrix, sometimes called the ''matrix unguis'', keratogenous membrane, nail matrix, or onychostroma, is the active tissue (or germinal matrix) that generates cells, which harden as they move outward from the nail root to the nail plate. It is the part of the nail bed that is beneath the nail and contains nerves, lymph and blood vessels. The matrix produces cells that become the nail plate. The width and thickness of the nail plate is determined by the size, length, and thickness of the matrix, while the shape of the finger ...

Thumb
The thumb is the first digit of the hand, next to the index finger. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit. The Medical Latin English noun for thumb is ''pollex'' (compare ''hallux'' for big toe), and the corresponding adjective for thumb is ''pollical''. Definition Thumb and fingers The English word ''finger'' has two senses, even in the context of appendages of a single typical human hand: # Any of the five terminal members of the hand. # Any of the four terminal members of the hand, other than the thumb Linguistically, it appears that the original sense was the first of these two: (also rendered as ) was, in the inferred Proto-Indo-European language, a suffixed form of (or ), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve, or stem from, concepts of fiveness. The thumb shares the following with each of the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ed Summers
Oren Edgar Summers (December 5, 1884 – May 12, 1953), nicknamed "Kickapoo Ed", was an American right-handed pitcher in Major League Baseball who played five seasons with the Detroit Tigers from 1908 to 1912. Biography Summers was born in Ladoga, Indiana, and attended Wabash College in Crawfordsville, Indiana. He began his playing career in the American Association before joining the Tigers in the American League in 1908. In his rookie season, Summers emerged as the Tigers' best pitcher, finishing with a 1.64 ERA in 301 innings pitched and a 24–12 win–loss record. On September 25, 1908, the Tigers were two games back of the Cleveland Naps for the AL pennant and were scheduled to play a doubleheader. Summers threw two complete game victories, winning the second game 1–0 after throwing 10 shutout innings. Summers is still the only player to have pitched a pair of complete game victories and throw more than eighteen innings. The Tigers went on to win the pennant and return ...

Knuckle
The knuckles are the joints of the fingers. The word is cognate to similar words in other Germanic languages, such as the Dutch "knokkel" (knuckle) or German "Knöchel" (ankle), i.e., ''Knöchlein'', the diminutive of the German word for bone (''Knochen''). Anatomically, it is said that the knuckles consist of the metacarpophalangealUtah Mountain BikingThumb Sprain First as metacarpo. (MCP) and interphalangeal (IP) joints of the finger. The knuckles at the base of the fingers may be referred to as the 1st or major knuckles while the knuckles at the midfinger are known as the 2nd and 3rd, or minor, knuckles. However, the ordinal terms are used inconsistently and may refer to any of the knuckles. Cracking The physical mechanism behind the popping or cracking sound heard when cracking joints such as knuckles has recently been elucidated by cine MRI to be caused by tribonucleation as a gas bubble forms in the synovial fluid that bathes the joint. Despite this evidence, many stil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
