A slot is a narrow opening in something, such as a keyway in a piece of machinery or a slit for a coin in a vending machine. You can also use it as a verb, meaning to insert or fit something into that space: He slotted the CD into the player. You can also use it as a noun, referring to the position of someone or something in a schedule or program: We have a slot open for an intern to work with our team for a year.
In aviation, a scheduled time and place for an aircraft to take off or land, issued by an airport or air-traffic authority: Air traffic controllers issue slots according to demand for runway capacity. The slot system has been very successful and has reduced flight delays significantly.
Although the technology of slot machines has changed dramatically over the years and computer-controlled models have largely replaced mechanical ones, their basic operation is still the same. The player pulls a handle to rotate a series of reels (typically three) with pictures printed on them. When the pictures line up with the pay line, the player wins a specified amount (called the payout).
Psychologists have found that people who play video slots reach a debilitating level of gambling addiction more quickly than people who play traditional casino games. In fact, they reach the debilitating level in a third of the time it takes to become addicted to blackjack, for example.
During World War II, the Germans developed and used a special type of gun to attack Allied ships from a distance by guiding a laser beam into their target. This technique was called a laser scan or a laser rangefinder, and it worked much faster than conventional ranging methods. Laser scans allowed ships to fire at enemy targets without the need for a radar scanner, which would have delayed their response time.
When a ship is undergoing laser scan, its speed and location are recorded by a computer. The data are then used to determine the optimal firing angle for the laser, which allows the ship to track its target and hit it with maximum accuracy. Laser scanning is also used for other purposes, such as to check the condition of ship hulls and for other maintenance purposes.
The Slot receiver is a quick wide receiver who often lines up in the backfield.
