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.

Redman (TV series)
Redman (レッドマン Reddoman) is a Japanese tokusatsu television series. A Kyodai Hero programme, it features the titular hero growing to immense size and fighting similarly sized monsters. Originally broadcast as 138 five-minute segments as part of the children's variety show Ohayo! Kodomo Show on Nihon TV, it was produced by Tsuburaya Productions. Redman was initially aired between April 3, 1972 to September 8 of that same year.
It is similar in many ways to the most famous of Kyodai Hero series', the Ultra Series; indeed, all enemy monsters featured were re-used from programmes produced as part of that franchise.
