Recoil

Recoil (often called knockback, kickback or simply kick) is the backward momentum of a gun when it is discharged. In technical terms, the recoil caused by the gun exactly balances the forward momentum of the projectile and exhaust gases (ejecta), according to Newton's third law. In most small arms, the momentum is transferred to the ground through the body of the shooter; while in heavier guns such as mounted machine guns or cannons, the momentum is transferred to the ground through its mount. In order to bring the gun to a halt, a forward counter-recoil force must be applied to the gun over a period of time. Generally, the counter-recoil force is smaller than the recoil force, and is applied over a time period that is longer than the time that the recoil force is being applied (i.e. the time during which the ejecta are still in the barrel of the gun). This imbalance of forces causes the gun to move backward until it is motionless.

A change in momentum results in a force, which according to Newton's second law is equal to the time derivative of the momentum of the gun. The momentum is equal to the mass of the gun multiplied by its velocity. This backward momentum is equal in magnitude, by the law of conservation of momentum, to the forward momentum of the ejecta (projectile(s), wad, propellant gases, etc...) from the gun. If the mass and velocity of the ejecta are known, it is possible to calculate a gun’s momentum and thus the energy. In practice, it is often simpler to derive the gun’s energy directly with a reading from a ballistic pendulum or ballistic chronograph.

Mace

Mace is the G.I. Joe Team's undercover operative. His real name is Thomas S. Bowman, and he was first released as an action figure in 1993. Mace was born in Denver, Colorado.

His primary military specialty is undercover surveillance. His secondary military specialty is intelligence. Mace has spent years undercover, working against Cobra and other criminal factions. He feeds information to fellow "Battle Corps" members, who then make the resulting raids and arrests.

Major Altitude

Major Altitude is the G.I. Joe Team's Battle Copter pilot. His real name is Robert D. Owens, and he was born in Rumford, Rhode Island. Major Altitude was first released as an action figure in 1991, as part of the Battle Copters line. He came exclusively with the "Battle Copter" vehicle. He was released again in 1993, as part of a mail-in special called "Terrifying Lasers of Destruction". He was packaged with a Cobra agent, another helicopter pilot, called Interrogator.

Millennium

A millennium (plural millennia) is a period of time equal to 1000 years. It derives from the Latin mille, thousand, and annus, year. It is often, but not always, related to a particular dating system.

Sometimes, it is used specifically for periods of a thousand years that begin at the starting point (initial reference point) of the calendar in consideration (typically the year "1"), or in later years that are whole number multiples of a thousand years after it. The term can also refer to an interval of time beginning on any date. Frequently in the latter case (and sometimes also in the former) it may have religious or theological implications (see millenarianism). Sometimes in use, such an interval called a "millennium" might be interpreted less precisely, i.e., not always being exactly 1000 years long. It could be, for example, 1050, etc.

Counting years

There are two methods of counting years, current years (the count begins at the epoch) and elapsed years (the count is of completed years since the epoch). This latter method is used in India.

1,000 Years

1,000 Years is the first solo album by The Corin Tucker Band, released on October 5, 2010, and the first album Tucker released since Sleater-Kinney went on "hiatus" in 2006. She recorded the album along with Seth Lorinczi and Julianna Bright of both Golden Bears and Circus Lupus, as well as Sara Lund of Hungry Ghost and Unwound. Lorinzci was also the album's producer. The album received generally positive reviews from critics, many of whom noted that the album was stylistically more muted than her work with Sleater-Kinney. As of August 2012, the album has sold about 8,000 copies and peaked at #9 on the Top Heatseekers Chart.

Background and recording

Tucker told The Portland Mercury that she was recording the album in April 2010, and said it was "definitely more of a middle-aged mom record, in a way. It's not a record that a young person would write." The origins of these songs lie in material Tucker wrote for live performances in early 2009 in Portland, after which many people encouraged her to make her own album. Tucker said that she wanted to create something both quiet and powerful in the making of this album. Tucker feels that Seth Lorinczi lent the album many of its creative ideas, and has stated, "He brought so many amazing ideas to the songs, it was an entirely new foray." Some of the album's tracks were written initially for the Twilight: New Moon soundtrack. The songs in question include closer "Miles Away".
