(Mathematics) The least interval in the range of the independent variable of a periodic function of a real variable in which all possible values of the dependent variable are assumed.

A unit of time equal to^{1} /_{60} of an hour or 60 seconds. &diamf3; A sidereal minute is^{1} /_{60} of a sidereal hour, and a mean solar minute is^{1} /_{60} of a mean solar hour.

The period (365 days, 5 hours, 48 minutes, and 46 seconds of mean solar time) spent by the sun in making its apparent passage from vernal equinox to vernal equinox: the year of the seasons

Any of the four arbitrary divisions of the year, characterized chiefly by differences in temperature, precipitation, amount of daylight, and plant growth; spring, summer, fall (or autumn), or winter

(Mathematics) A mathematical object, typically a set of sets, that is usually structured to define a range across which variables or other objects (such as a coordinate system) can be defined.

The degree of brightness of a star or other celestial body, measured on a logarithmic scale in which lower numbers mean greater brightness, such that a decrease of one unit represents an increase in brightness by a factor of 2.512. An object that is 5 units less than another object on the magnitude scale is 100 times more luminous. Because of refinements in measurement after the zero point was assigned, very bright objects have negative magnitudes. &diamf3; The brightness of a celestial body as seen from Earth is called its apparent magnitude . (When unspecified, an object's magnitude is normally assumed to be its apparent magnitude.) The dimmest stars visible to the unaided eye have apparent magnitude 6, while the brightest star in the night sky, Sirius, has apparent magnitude −1.4. The full Moon and the Sun have apparent magnitudes of −12.7 and −26.8 respectively. &diamf3; The brightness of a celestial body computed as if viewed from a distance of 10 parsecs (32.6 light-years) is called its absolute magnitude . Absolute magnitude measures the intrinsic brightness of a celestial object rather than how bright it appears on Earth, using the same logarithmic scale as for apparent magnitude. Sirius has an absolute magnitude of 1.5, considerably dimmer than Rigel which, though its apparent magnitude is 0.12, has an absolute magnitude of −8.1. Stars that appear dim in the night sky but have bright absolute magnitudes are much farther from Earth than stars that shine brightly at night but have relatively dim absolute magnitudes. The Sun, a star of only medium brightness, has an absolute magnitude of 4.8. &diamf3; The degree of total radiation emitted by a celestial body, including all infrared and ultraviolet radiation in addition to visible light, is called its bolometric magnitude . Bolometric magnitude is generally measured by applying a standard correction to an object's absolute magnitude.

These pairs of observations have shown a parallax from which the elevation of the objects above the earth, the lengths and directions of their courses, &c. could be computed.

Wool coats are available in short, medium and long lengths.

But a positive identity of pitch cannot be claimed for any period of time, and certainly not for the early organs; the foot-rule of the organ-builder, which had to do with the lengths of the pipes, and which varied in every country and province, could easily cause a difference of a semitone.
