Offside (ice hockey)

In ice hockey, a play is offside if a player on the attacking team enters the offensive zone before the puck, unless the puck is sent or carried there by a defending player. When an offside violation occurs, a linesman will stop play. A faceoff is then held at a neutral ice spot closest to the infraction to restart play.

Rules

The National Hockey League (NHL) and International Ice Hockey Federation (IIHF) apply similar rules for determining offside. A player is judged to be offside if both of their skates completely cross the blue line dividing their offensive zone from the neutral zone before the puck completely crosses the same line. In both organizations, it is the position of a player's skates that are important. They cannot use their stick or other part of their body to remain onside. The lone caveat to this rule is that an attacking player's skates may precede the puck into the attacking zone when they are skating backwards and if they are in control of the puck.

Ice hockey

Ice hockey is a contact team sport played on ice, usually in a rink, in which two teams of skaters use their sticks to shoot a vulcanized rubber puck into their opponent's net to score points. Ice hockey teams usually consist of four lines of three forwards, three pairs of defencemen, and two goaltenders. Normally, each team has five players who skate up and down the ice trying to take the puck and score a goal against the opposing team.

A fast-paced, physical sport, hockey is most popular in areas of North America (particularly Canada and the northern United States) and northern and western Europe. In North America, the National Hockey League (NHL) is the highest level for men's hockey and the most popular. The Kontinental Hockey League (KHL) is the highest league in Russia and much of Eastern Europe. Ice hockey is the official national winter sport of Canada, where the game enjoys immense popularity. The International Ice Hockey Federation (IIHF) is the formal governing body for international ice hockey. The IIHF manages international tournaments and maintains the IIHF World Ranking. Worldwide, there are ice hockey federations in 74 countries.

Ice

Ice is water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color.

In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far as the Oort cloud. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surface – particularly in the polar regions and above the snow line – and, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes.

Ice molecules can exhibit up to sixteen different phases (packing geometries) that depend on temperature and pressure. When water is cooled rapidly (quenching), up to three different types of amorphous ice can form depending on the history of its pressure and temperature. When cooled slowly correlated proton tunneling occurs below 20 K giving rise to macroscopic quantum phenomena. Virtually all the ice on Earth's surface and in its atmosphere is of a hexagonal crystalline structure denoted as ice Ih (spoken as "ice one h") with minute traces of cubic ice denoted as ice Ic. The most common phase transition to ice Ih occurs when liquid water is cooled below 0°C (273.15K, 32°F) at standard atmospheric pressure. It may also be deposited directly by water vapor, as happens in the formation of frost. The transition from ice to water is melting and from ice directly to water vapor is sublimation.

Hockey

Hockey is a family of sports in which two teams play against each other by trying to maneuver a ball or a puck into the opponent's goal using a hockey stick. In many areas, one sport (typically field hockey or ice hockey) is generally referred to simply as hockey.

Etymology

The first recorded use of the word hockey is in the 1773 book Juvenile Sports and Pastimes, to Which Are Prefixed, Memoirs of the Author: Including a New Mode of Infant Education by Richard Johnson (Pseud. Master Michel Angelo), whose chapter XI was titled "New Improvements on the Game of Hockey". The belief that hockey was mentioned in a 1363 proclamation by King Edward III of England is based on modern translations of the proclamation, which was originally in Latin and explicitly forbade the games "Pilam Manualem, Pedivam, & Bacularem: & ad Canibucam & Gallorum Pugnam". The English historian and biographer John Strype did not use the word "hockey" when he translated the proclamation in 1720.

The word hockey itself is of unknown origin. One explanation is that it is a derivative of hoquet, a Middle French word for a shepherd's stave. The curved, or "hooked" ends of the sticks used for hockey would indeed have resembled these staves. Another explanation is that the cork bungs that replaced wooden balls in the 18th century came from barrels containing "hock" ale, also called "hocky".
