Drop (unit)

The drop is a unit of measure of volume, the amount dispensed as one drop from a dropper or drip chamber. It is often used in giving quantities of liquid drugs to patients, and occasionally in cooking.

The volume of a drop is not well-defined: it depends on the device and technique used to produce the drop, on the strength of the gravitational field, and on the density and the surface tension of the liquid.

There are several exact definitions of a "drop":

Drop (music)

A drop in popular music, especially electronic music styles, is a point in a music track where a switch of rhythm or bass line occurs and usually follows a recognizable build section and break.

The term "drop" comes from the composer or producer "dropping in" the primary rhythmic and foundational elements previously hinted at into the mix more or less at once. Related terms, typically describing certain types of drops, include "beat-up" (so named because it is a point where the producer brings up the foundational kick drum beat after having faded it down during a break or buildup) and "climax" (typically describing a single particularly striking drop heard late in the track).

Types

Many genres of EDM can have more than one drop during a track, especially if the song is built on a "dance-pop" verse/chorus with vocals; a drop of some kind is typically heard somewhere during each chorus as the high point of that verse/chorus cycle. Most genres, however, tend to emphasize a single drop as the beginning of the high point, or climax, of the entire track; in vocal subgenres this is typically the last repetition of the chorus, while in nonvocal genres it typically occurs in the last quarter of the track.

Overhand (boxing)

An overhand (or overcut or drop) is a semi-circular and vertical punch thrown with the rear hand. It is usually employed when the opponent is bobbing or slipping. The strategic utility of the drop relying on body weight can deliver a great deal of power.

Simplified molecular-input line-entry system

The simplified molecular-input line-entry system (SMILES) is a specification in form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.

The original SMILES specification was initiated by David Weininger at the USEPA Mid-Continent Ecology Division Laboratory in Duluth in the 1980s. Acknowledged for their parts in the early development were "Gilman Veith and Rose Russo (USEPA) and Albert Leo and Corwin Hansch (Pomona College) for supporting the work, and Arthur Weininger (Pomona; Daylight CIS) and Jeremy Scofield (Cedar River Software, Renton, WA) for assistance in programming the system." The Environmental Protection Agency funded the initial project to develop SMILES.

It has since been modified and extended by others, most notably by Daylight Chemical Information Systems. In 2007, an open standard called "OpenSMILES" was developed by the Blue Obelisk open-source chemistry community. Other 'linear' notations include the Wiswesser Line Notation (WLN), ROSDAL and SLN (Tripos Inc).
