Clockwork refers to the inner workings of either a mechanical clock (where it is also called a movement) or another device that operates in a similar fashion (such as a dial indicator). Specifically, the term refers to mechanisms utilizing a complex series of gears.
A clockwork motor is a clockwork device mechanically powered by a mainspring, a spiral torsion spring of metal ribbon. Energy is stored in the mainspring manually by winding it up, turning a key attached to a ratchet which twists the mainspring tighter. Then the force of the mainspring turns the clockwork's gears, until the stored energy is used up. The adjective wind-up refers to mainspring-powered clockwork devices, which include clocks and watches, kitchen timers, music boxes, and wind-up toys.
One of the earliest known examples of a clockwork mechanism is the Antikythera mechanism, a first-century BC geared analogue computer, somewhat astrolabe-like, for calculating astronomical positions and eclipses, recovered from a Greek shipwreck. There are many other accounts of clockwork devices in ancient Greece, even in its mythology, and the mechanism itself is sophisticated enough to indicate a significant history of lesser devices leading up to its creation.
"Clockwork" is a song recorded by American country music artist Easton Corbin. It was released in January 2014 as the lead single from Corbin's third studio album, About to Get Real. The song was written by Carson Chamberlain, Ashley Gorley and Wade Kirby.
When asked about the song Corbin stated, “I’m very, VERY excited to have new music out now for my fans. I’m excited especially to release a song like ‘Clockwork...’‘Clockwork’ is a good reflection of my country roots and it shows that I’m growing as an artist. I think when my fans hear this song they will get a good taste of how my upcoming album is going to be.”
Matt Bjorke of Roughstock rated Clockwork 3.5 stars. He states, "as far as lead singles from upcoming albums go, “Clockwork” is the kind of song which SHOULD do well at radio. It has the contemporary melody —there’s even audible steel guitar fills — and a solid vocal from Easton Corbin."
The music video was directed by Shaun Silva and premiered in April 2014.
"Clockwork" is the fourth single by American rapper Juelz Santana from his second studio album What the Game's Been Missing! (2005).
The music video for the song was directed by Dale "Rage" Resteghini.
A stun grenade, also known as a flash grenade, flashbang or sound bomb, is a non-lethal explosive device used to temporarily disorient an enemy's senses. It is designed to produce a blinding flash of light and an intensely loud "bang" of greater than 170 decibels (dB) without causing permanent injury. It was first used by the British Army's SAS in the late 1970s.
The flash produced momentarily activates all photoreceptor cells in the eye, making vision impossible for approximately five seconds, until the eye restores itself to its normal, unstimulated state. An afterimage will also be visible for a considerable time, impairing the victim's ability to aim with precision. The loud blast is meant to cause temporary loss of hearing, and also disturbs the fluid in the ear, causing loss of balance.
The concussive blast of the detonation can still injure, and the heat created can ignite flammable materials such as fuel. The fires that occurred during the Iranian Embassy siege in London were caused by stun grenades.
