Chameleon Oil Pattern
The Chameleon oil pattern is a pattern of oil used by the Professional Bowlers Association in tournament play. It is among the numerous Animal Patterns. The current rendition of the Chameleon pattern is 39 feet in length. This forces players to play a specific part of the lane because of the way the oil is layered in "strips". The lane conditions dictate where the bowler should play. This is considered a "retro" approach to pattern designing. The Chameleon pattern varies in a large range of scores (low to high), as does the bowlers' approach to the pattern. There isn't one specific bowling style that is most effective on this pattern, because there can be multiple target lines that dictate how much the ball will hook, and thus how much curvature In mathematics, curvature is any of several strongly related concepts in geometry. Intuitively, the curvature is the amount by which a curve deviates from being a straight line, or a surface deviates from being a plane. For curves, ...

Professional Bowlers Association
The Professional Bowlers Association (PBA) is the major sanctioning body for the sport of professional ten-pin bowling in the United States. Headquartered in Chicago, Illinois, the PBA membership consists of over 3,000 members worldwide. Members include "pro shop" owners and workers, teaching professionals and bowlers who compete in the various events put on by the Association. The PBA also oversees competition between professional bowlers via the following tours: * PBA Tour – An annual calendar of events, currently running from January to December each year. * PBA Regional Tour – Allows PBA members and qualifying amateurs to compete in weekend events. The Tour consists of seven regions: Central, East, Midwest, Northwest, South, Southwest, and West. * PBA50/60 Tours – Originally the PBA Senior Tour, it was split in 2013 and now based on age. Set up like the PBA Tour, but allowing PBA members aged 50 years and older, and after the 2013 rebranding, a different tour for me ...

Curvature
In mathematics, curvature is any of several strongly related concepts in geometry. Intuitively, the curvature is the amount by which a curve deviates from being a straight line, or a surface deviates from being a plane. For curves, the canonical example is that of a circle, which has a curvature equal to the reciprocal of its radius. Smaller circles bend more sharply, and hence have higher curvature. The curvature ''at a point'' of a differentiable curve is the curvature of its osculating circle, that is the circle that best approximates the curve near this point. The curvature of a straight line is zero. In contrast to the tangent, which is a vector quantity, the curvature at a point is typically a scalar quantity, that is, it is expressed by a single real number. For surfaces (and, more generally for higher-dimensional manifolds), that are embedded in a Euclidean space, the concept of curvature is more complex, as it depends on the choice of a direction on the surfac ...

Chameleon
Chameleons or chamaeleons ( family Chamaeleonidae) are a distinctive and highly specialized clade of Old World lizards with 202 species described as of June 2015. The members of this family are best known for their distinct range of colors, being capable of shifting to different hues and degrees of brightness. The large number of species in the family exhibit considerable variability in their capacity to change color. For some, it is more of a shift of brightness (shades of brown); for others, a plethora of color-combinations (reds, yellows, greens, blues) can be seen. Chameleons are distinguished by their zygodactylous feet, their prehensile tail, their laterally compressed bodies, their head casques, their projectile tongues, their swaying gait, and crests or horns on their brow and snout. Chameleons' eyes are independently mobile, and because of this there are two separate, individual images that the brain is analyzing of the chameleon’s environment. When hunting prey, th ...
