Time

The minute is a unit of time equal to 1/60th of an hour or 60 seconds. For other uses see Time (disambiguation Time is a component of a measuring system used to sequence events to compare the durations of The hour (symbol h) is a unit of Time. It is not an SI unit but is accepted for use with the SI The second ( SI symbol s) sometimes abbreviated sec, is the name of a unit of Time, and is the International System of Units Some rare minutes have 59 or 61 seconds; see leap second. A leap second is a one- Second adjustment that keeps broadcast standards for time of day close to mean solar time. The minute is not an SI unit, however it is accepted for use with SI units.

The symbol for minute or minutes is min.

The fact that an hour contains 60 minutes is probably due to influences from the Babylonians, who used a base-60 or sexagesimal counting system. Babylon was a City-state of ancient Mesopotamia, the remains of which can be found in present-day Al Hillah, Babil Province, Iraq A numeral system (or system of numeration) is a Mathematical notation for representing numbers of a given set by symbols in a consistent manner

Geometry

In geometry, the minute is a unit of angle, 1/60th of a degree. Geometry ( Greek γεωμετρία; geo = earth metria = measure is a part of Mathematics concerned with questions of size shape and relative position In Geometry and Trigonometry, an angle (in full plane angle) is the figure formed by two rays sharing a common Endpoint, called This article describes the unit of angle For other meanings see Degree. It is also known as a minute of angle or minute of arc and can further be divided into 60 seconds of arc. A minute of arc, arcminute, or MOA is a unit of angular measurement, equal to one sixtieth (1/60 of one degree. A minute of arc, arcminute, or MOA is a unit of angular measurement, equal to one sixtieth (1/60 of one degree.

The symbol for a minute of arc is a prime (′). The prime symbol ( ′  double prime symbol ( &Prime  triple prime symbol ( ‴  etc For example, fifteen minutes could be written 15′. However, more commonly an apostrophe, or single quote (U+0027), is used.

Astronomy

In astronomy, the minute is a unit of angle, the minute of right ascension. Astronomy (from the Greek words astron (ἄστρον "star" and nomos (νόμος "law" is the scientific study Right ascension (abbrev RA; symbol α) is the Astronomical term for one of the two Coordinates of a point on the Celestial sphere It is equal to 1/60th of an hour of right ascension and can be further divided into 60 seconds of right ascension.

The symbol for a minute of right ascension is min.

The Earth turns on its polar axis through fifteen minutes of arc in every minute of sidereal time. EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 A geographical pole, or geographic pole, is either of two fixed points on the surface of a spinning body or Planet, at 90 degrees from the Equator, based A rotation is a movement of an object in a circular motion A two- Dimensional object rotates around a center (or point) of rotation Sidereal time is a measure of the position of the Earth in its rotation around its axis or time measured by the apparent Diurnal motion of the Vernal equinox One minute of arc at the Earth's equator is approximately one nautical mile. The equator (sometimes referred to colloquially as "the Line") is the intersection of the Earth 's surface with the plane perpendicular to the A nautical mile or sea mile is a unit of Length. It corresponds approximately to one minute of Latitude along any meridian.

Origin

The first division was originally known as a "prime minute", from Latin "(pars) minuta prima", meaning "first minute (i. e. small) part (or division)" of the hour. Likewise, the second was known as a "second minute", meaning "the second small division" of the hour. The second ( SI symbol s) sometimes abbreviated sec, is the name of a unit of Time, and is the International System of Units
