Third (curling)

In curling, a third (alternatively, vice, vice-skip or mate) is the team member who delivers the second-to-last pair of a team's stones in an end. The third is in charge of strategy and directing the sweepers when the skip is delivering their stones, but sweeps for the lead and second. The two vices are responsible for determining and recording the score after each end, and in most clubs, will determine by lot which team begins a game with the hammer and what colour stones each team will use. The third position requires a curler adept at executing shots with a high degree of accuracy, especially draws and other finesse shots, as the third needs to set up the house for the skip's stones.

Third (Big Star album)

Third, also (since 1985) re-issued as Sister Lovers, is the third studio album by American rock band Big Star. It was recorded in 1974. Though Ardent Studios created test pressings for the record in 1975, a combination of financial issues, the uncommercial sound of the record, and lack of interest from singer Alex Chilton and drummer Jody Stephens in continuing the project prevented the album from ever being properly finished or released at the time of its recording. It was eventually released in 1978 by PVC Records.

After two commercially unsuccessful albums, Third documents the band's deterioration as well as the declining mental state of singer Alex Chilton. It has since gone on to become one of the most critically acclaimed albums in history and is considered a cult album. Rolling Stone placed the album at number 449 on its "500 Greatest Albums of All Time" list.

Composition and recording

After the commercial failure of Big Star's first two albums, #1 Record (1972) and Radio City (1974), Alex Chilton and Jody Stephens returned to Ardent Studios in late 1974—accompanied by what biographer Bruce Eaton describes as "a large and revolving cast of Memphis musicians"—to record, under producer Jim Dickinson, "a batch of starkly personal, often experimental, and by turns beautiful and haunting songs that were anything but straight-up power pop." Ardent's John Fry, producer of the first two albums and also involved with the third, recalled that the sessions were burdened by severe personal issues; Eaton tells how Fry "finally called a halt to the escalating madness" and the album was mastered by Larry Nix on 13 February 1975.

Degree (angle)

A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of plane angle, representing ¹⁄₃₆₀ of a full rotation. It is not an SI unit, as the SI unit for angles is radian, but it is mentioned in the SI brochure as an accepted unit. Because a full rotation equals 2π radians, one degree is equivalent to π/180 radians.

History

The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Persian calendar, used 360 days for a year. The use of a calendar with 360 days may be related to the use of sexagesimal numbers.

Another theory is that the Babylonians subdivided the circle using the angle of an equilateral triangle as the basic unit and further subdivided the latter into 60 parts following their sexagesimal numeric system. The earliest trigonometry, used by the Babylonian astronomers and their Greek successors, was based on chords of a circle. A chord of length equal to the radius made a natural base quantity. One sixtieth of this, using their standard sexagesimal divisions, was a degree.
