dip,

in agriculture, method of treating animals (chiefly livestock) infested with skin parasites such as mites, ticks, and warbles. The animal is dipped into or forced to swim through a tank filled with an insecticideinsecticides,
chemical, biological, or other agents used to destroy insect pests; the term commonly refers to chemical agents only. Chemical Insecticides

(engineering)
The vertical angle between the sensible horizon and a line to the visible horizon at sea, due to the elevation of the observer and to the convexity of the earth's surface. Also known as dip of horizon.
(geology)
The angle that a stratum or fault plane makes with the horizontal. Also known as angle of dip; formation dip; true dip.
A pronounced depression in the land surface.

i. The angle between the local horizon and the lines of force of the terrestrial magnetic field. Its value is maximum near the poles. Also called a magnetic dip, magnetic latitude, or magnetic inclination.
ii. The angle between a magnetic compass-needle perfectly poised, or on the horizontal axis, and the local horizontal plane. Also called a magnetic inclination or dip angle.
iii. The vertical angle between the true horizon and the apparent or visible horizon. Dip is a function of the height of the eye (i.e., the vertical distance of the observer's eye from the earth's surface).
iv. To dip or to lower one's wing, generally as a sign of recognition or acknowledgment.

1. a depression, esp in a landscape
2. the angle of slope of rock strata, fault planes, etc., from the horizontal plane
3. the angle between the direction of the earth's magnetic field and the plane of the horizon; the angle that a magnetic needle free to swing in a vertical plane makes with the horizontal

(3) (Dual In-line Package) A common, mostly-rectangular chip housing with leads (pins) on both sides. Tiny wires bond the chip to metal leads that wind their way down into spider-like feet. The DIP is plugged into a socket or inserted into holes in the printed circuit board and soldered. See DIP switch, CDIP, CERDIP and chip package.


The DIP
Introduced in the 1960s, the DIP package was widely used for decades and still exists to hold microcontrollers and other electronic circuits.
