Time-out (sport)

In sports, a time-out is a halt in the play. This allows the coaches of either team to communicate with the team, e.g., to determine strategy or inspire morale, as well as to stop the game clock. Time-outs are usually called by coaches or players, although for some sports, TV timeouts are called to allow media to air commercial breaks. Teams usually call timeouts at strategically important points in the match, or to avoid the team being called for a delay of game-type violation, such as the five-second rule in basketball.

Gridiron football

In gridiron football, the use and rationing of time-outs is a major part of strategy; calling time-out stops the clock (which normally is running between plays except in the case of a penalty, an incomplete pass, officials requiring time to re-spot the ball and/or down markers, or when the ball is run out of bounds), extending the time a team has to score. Timeouts can be called by both players (typically the quarterback or a linebacker) and the head coach. The number of timeouts is limited to three per team per half in the National Football League, and college and high school levels; to two per half in amateur Canadian football, and to one per half in the Canadian Football League. Unused timeouts carry over between the first and second quarters and between the third and fourth quarters, but they do not carry over between halves. If overtime is required in the NFL, each team is given two timeouts during a fifteen-minute sudden-death period, while in college football each team gets one timeout per possession. If a timeout above these limits is called, it is ignored and no penalty is assessed.

Timeout (computing)

In telecommunication and related engineering (including computer networking and programming), the term timeout or time-out has several meanings, including:

Timeout allows a more efficient usage of limited resources without requiring additional interaction from the agent interested in the goods that cause the consumption of these resources. The basic idea is that in situations where a system must wait for something to happen, rather than waiting indefinitely, the waiting will be aborted after the timeout period has elapsed. This is based on the assumption that further waiting is useless, and some other action is necessary.

Zodiac

In both astrology and historical astronomy, the zodiac (Greek: ζῳδιακός, zōidiakos) is a circle of twelve 30° divisions of celestial longitude that are centered upon the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. The paths of the Moon and visible planets also remain close to the ecliptic, within the belt of the zodiac, which extends 8-9° north or south of the ecliptic, as measured in celestial latitude. Because the divisions are regular, they do not correspond exactly to the boundaries of the twelve constellations after which they are named.

Historically, these twelve divisions are called signs. Essentially, the zodiac is a celestial coordinate system, or more specifically an ecliptic coordinate system, which takes the ecliptic as the origin of latitude, and the position of the Sun at vernal equinox as the origin of longitude.

Usage

The zodiac was in use by the Roman era, based on concepts inherited by Hellenistic astronomy from Babylonian astronomy of the Chaldean period (mid-1st millennium BC), which, in turn, derived from an earlier system of lists of stars along the ecliptic. The construction of the zodiac is described in Ptolemy's vast 2nd century AD work, the Almagest.
