Slider

In baseball, a slider is a breaking ball pitch that tails laterally and down through the batter's hitting zone; it is thrown with speed less than a fastball but greater than the pitcher's curveball.

The break on the pitch is shorter than that of the curveball, and the release technique is 'between' those of a curveball and a fastball. The slider is similar to the cutter, a fastball pitch, but is more of a breaking ball than the cutter. The slider is also known as a yakker or a snapper.

Slider continuum

Depending on velocity, a pitch can fall anywhere on the continuum from "fastball" to "slider":

The most notable difference between a slider and curveball is that the curveball delivery includes a downward yank on the ball as it is released in addition to the lateral spin applied by the slider grip. The slider is released off the index finger, while the curveball is released off the middle finger. If the pitcher is snapping his wrist as he throws, and the movement is more downward than sideways, then he is probably throwing a curveball or slurve, and not a true "slider". When throwing a slider, the pitcher should create a "dot" on the baseball; this means that as the ball approaches home plate, the rotation of the ball is forming a dot. On a good slider, the "dot" will be down where it is not noticeable for a hitter to pick up. From the batter's perspective, this dot appears white, whereas the dot is red for a curve ball (created by the seam movement), allowing many skilled batters to immediately recognize the type of pitch. By having the dot on the bottom part of the ball, the pitcher will create good depth to the pitch. A good, hard slider has a slight break across the plate and a slight drop on its plane to the hitter.

Slider (computing)

A slider or track bar is a graphical control element with which a user may set a value by moving an indicator, usually in a horizontal fashion. In some cases user may also click on a point on the slider to change the setting. It is different from a scrollbar in that it is not continuous but used to adjust a value without changing the format of the display or the other information on the screen.

Usage with progress bars

Sliders are also combined with progress bars in the playback of streaming media over a network connection (e.g., YouTube videos) in order to show the content buffering position versus the playback position. This is done by superimposing a colored shaded area (progress bar) on top of the slider, indicating whether the user can "jump" forward or not.

Slider (cricket)

In cricket, a slider is a type of delivery bowled by a wrist spin bowler. Whereas a topspinner is released with the thumb facing the batsman, a slider is bowled in a similar manner to a legbreak, but instead of imparting sidespin with the third finger, the bowler allows his fingers to roll down the back of the ball, providing a mixture of sidespin and backspin. Whereas a topspinner tends to dip more quickly and bounce higher than a normal delivery, a slider does the opposite: it carries to a fuller length and bounces less than the batsman might expect. The sliders will typically head towards the batsman with a scrambled seam (with the ball not spinning in the direction of the seam, so the seam direction is not constant, unlike in conventional spin bowling). This has less effect on the flight and bounce but absence of leg spin may deceive the batsman. Frequently the slider is bowled with a mixture of side spin and backspin. This has the effect of making the ball harder to differentiate from the leg break for the batsmen without reducing the mechanical effects caused by the backspin. This delivery may skid straight on or it may turn a small amount.

Cellophane

Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases, bacteria and water makes it useful for food packaging. "Cellophane" is in many countries a registered trade mark of Innovia Films Ltd based in Wigton, Cumbria, United Kingdom.

Production

Cellulose from wood, cotton, hemp or other sources is dissolved in alkali and carbon disulfide to make a solution called viscose, which is then extruded through a slit into a bath of dilute sulfuric acid and sodium sulfate to reconvert the viscose into cellulose. The film is then passed through several more baths, one to remove sulfur, one to bleach the film, and one to add glycerin to prevent the film from becoming brittle.

A similar process, using a hole (a spinneret) instead of a slit, is used to make a fibre called rayon. Chemically, cellophane, rayon and cellulose are polymers of glucose and contain the chemical elements carbon, hydrogen and oxygen.

History

Cellophane was invented by Swiss chemist Jacques E. Brandenberger while employed by Blanchisserie et Teinturerie de Thaon. In 1900, inspired by seeing a wine spill on a restaurant's tablecloth, he decided to create a cloth that could repel liquids rather than absorb them. His first step was to spray a waterproof coating onto fabric, and he opted to try viscose. The resultant coated fabric was far too stiff, but the clear film easily separated from the backing cloth, and he abandoned his original idea as the possibilities of the new material became apparent.

The Troggs

The Troggs (originally called The Troglodytes) are an English rock band formed in Andover, Hampshire in 1964. They had a number of hits in the United Kingdom and the United States. Their most famous songs include the U.S. chart-topper "Wild Thing", "With a Girl Like You" and "Love Is All Around", all of which sold over 1 million copies and were awarded gold discs. "Wild Thing" is ranked #257 on the Rolling Stone magazine's list of The 500 Greatest Songs of All Time and was an influence on garage rock and punk rock.

History

Reg Presley (vocals) and Ronnie Bond (drums) were childhood friends and in the early 1960s formed an R&B band in their home town of Andover. In 1964 they were joined by Pete Staples (bass guitar) and Chris Britton (guitar) and became the Troggs. They were signed by Larry Page, manager of the Kinks, in 1965. They recorded on Page's Page One Records, and Page also leased them to CBS for debut single "Lost Girl". Their most famous hit was the single "Wild Thing" (written by Chip Taylor) (the song on the b-side of the single depended on the country where it was sold), which with the help of television exposure on Thank Your Lucky Stars reached number 2 in the UK (c/w Reg Presley's song "From Home") and number 1 in the United States in July 1966. Its combination of a simple heavy guitar riff and flirtatious lyrics helped it to quickly become a garage rock standard. It was recorded in one complete take (take two) at Olympic Studios in London, with Keith Grant engineering. Because of a dispute over US distribution rights, "Wild Thing" was released (along with the first album of the same name) on two labels: Fontana and Atco. The band's success in the US was also limited by not touring there until 1968.
