The drop is a unit of measure of volume, the amount dispensed as one drop from a dropper. 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.[1]
There are several exact definitions of a "drop":
- the "metric" drop, 1/20 mL (50 μL)[2]
- in medicine, IV drips deliver 10, 15, or 20 drops per mL for macrodrip, 60 per mL for microdrip[3]
- an informal (and incorrect) synonym for minim, the smallest unit of fluid measure in the Apothecaries' systems of the United States customary units, Imperial units, and pre-1824 English units equal to 1/60 of a fluid dram or 1/480 of a fluid ounce
- prior to the adoption of the minim in the early 19th century, the smallest unit of fluid measure in the Apothecaries' systems of the United States customary units and pre-1824 English units, inexact, but presumed to be equal to 1/60 of a fluid dram or 1/480 of a fluid ounce
History [link]
In the first decade of the 19th century, the minim, the smallest unit of Apothecary Measure, was promoted by the pharmaceutical and medical establishments as an alternative to the drop.[4] It was noted that the size of a drop can vary considerably depending on the viscosity and specific gravity of the fluid, as well as the size and shape of the vessel from which it is poured. (At the time, surface tension was not well-understood.) The minim came with a set of procedures for ensuring accurate measurement, specifically, diluting powerful medicines that had previously been measured by the drop, then using a "minimometer" or "minim glass" (graduated pipette) with minim marks at regular intervals. The minim was defined as one 60th of a fluid dram or one 480th of a fluid ounce.[5] This is equal to about 61.6 μL (U.S.) or 59.2 μL (Britain).
Pharmacists have since moved to metric measurements, with a drop being rounded to exactly 0.05 mL (that is, 20 drops per milliliter). In hospitals, intravenous tubing is used to deliver medication in drops of various sizes ranging from 10 drops/mL to 60 drops/mL. A drop is abbreviated gtt, with gtts used for the plural. These abbreviations come from gutta, the Latin for drop.[6]

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.

Dilemma (song)
"Dilemma" is a song by American rapper Nelly, featuring American R&B singer Kelly Rowland. It was released on June 25, 2002 as the third single from the Nelly's second studio album Nellyville (2002), and the lead single from Rowland's debut solo album Simply Deep (2002). It was number one in ten countries, including the UK, the US and Australia, selling over 7.6 million copies worldwide. The song depicts the declaration of forbidden love by a female lover in a committed relationship, and the predicament the male protagonist must face.
In the 55th Anniversary of the Hot 100 issue of Billboard magazine, the song was ranked at number 75 on the all-time Hot 100 songs while at the end of 2009 was named the 11th most successful song from 2000 to 2009, on the Billboard Hot 100 Songs of the Decade. The song won a Grammy Award for Best Rap/Sung Collaboration at the 45th Grammy Awards. "Dilemma" was accredited internationally with 16 certifications.
Background and release
St. Louis producer Bam handed Nelly a skeleton track which producer Ryan Bower produced, which samples and contains elements from Patti LaBelle's "Love, Need and Want You" from her 1983 album I'm In Love Again. Upon hearing the beat, he began writing lyrics and then wrote a song out from it. Nelly decided to make the song a last-minute addition to his second album Nellyville, which had already been completed prior to Bam giving him the track. Once Nelly returned to the studio to record the track, his vision changed, wanting to add a female vocal onto it. He instantly thought of girl group Destiny's Child member Kelly Rowland, whom he had met during the TRL tour in 2001. Nelly called Rowland by phone and agreed. After a few days of recording, during which Rowland rerecorded her part many times to achieve it "just right", "Dilemma" was completed.
Dilemma (novel)
Dilemma is a 1999 novel from Australian author Jon Cleary. It was the sixteenth book featuring Sydney detective Scobie Malone and involves his investigation of a murder in his parent's town and a kidnapping.
