The Year's Best Science Fiction
''The Year's Best Science Fiction'' was a series of science fiction anthologies edited by American Gardner Dozois until his death in 2018. The series, which is unrelated to the similarly titled and themed '' Year's Best SF'', was published by St. Martin's Griffin. The collections were produced annually for 35 years starting in 1984. In the UK, the series was titled ''The Mammoth Book Of Best New Science Fiction'' and published by Robinson. '' The Fourth Annual Collection in the US'', in 1987, became the ''first'' book of the "Mammoth series" in the UK. For the next five years, from 1988 through 1993, the UK series was titled ''Best New SF'' (#2 through #7). Best of the Best series In 2005, Dozois edited the first "Best of the Best" compilation. A second volume was published in 2007. That compilation and the entire series were re-released as e-book An ebook (short for electronic book), also spelled as e-book or eBook, is a book publication made available in electronic fo ...

Twentieth Annual Collection
20 (twenty) is the natural number following 19 and preceding 21. A group of twenty units is sometimes referred to as a score. In mathematics Twenty is a composite number. It is also the smallest primitive abundant number. The Happy Family of sporadic groups is made up of twenty finite simple groups that are all subquotients of the friendly giant, the largest of twenty-six sporadic groups. Geometry An icosagon is a polygon with 20 edges. Bring's curve is a Riemann surface, whose fundamental polygon is a regular hyperbolic icosagon. Platonic solids The largest number of faces a Platonic solid can have is twenty faces, which make up a regular icosahedron. A dodecahedron, on the other hand, has twenty vertices, likewise the most a regular polyhedron can have. This is because the icosahedron and dodecahdron are duals of each other. Other fields Science 20 is the third magic number in physics. Biology In some countries, the number 20 is used as an index in measur ...

Seventeenth Annual Collection
An organ stop can be one of three things: *the control on an organ console that selects a particular sound *the row of organ pipes used to create a particular sound, more appropriately known as a ''rank'' *the sound itself Organ stops are sorted into four major types: principal, string, reed, and flute. This is a sortable list of names that may be found associated with electronic and pipe organ stops. Countless stops have been designed over the centuries, and individual organs may have stops, or names of stops, used nowhere else. This non-comprehensive list deals mainly with names of stops found on numerous Baroque, classical and romantic organs. Here are a few of the most common ones: See also * Abbatial church of Notre-Dame de Mouzon * Eight-foot pitch The system of describing organ pipes or harpsichord strings with a particular number of "feet" is a way of relating the pitch actually sounded by the pipe or the string to the conventional pitch assigned to the key ...

Sixteenth Annual Collection
16 (sixteen) is the natural number following 15 and preceding 17. It is the fourth power of two. In English speech, the numbers 16 and 60 are sometimes confused, as they sound similar. Mathematics 16 is the ninth composite number, and a square number: 42 = 4 × 4 (the first non-unitary fourth-power prime of the form ''p''4). It is the smallest number with exactly five divisors, its proper divisors being , , and . Sixteen is the only integer that equals ''m''''n'' and ''n''''m'', for some unequal integers ''m'' and ''n'' (m=4, n=2, or vice versa). It has this property because 2^=2\times 2. It is also equal to 32 (see tetration). The aliquot sum of 16 is 15, within an aliquot sequence of four composite members (16, 15, 9, 4, 3, 1, 0) that belong to the prime 3-aliquot tree. *Sixteen is the largest known integer , for which 2^n+1 is prime. *It is the first Erdős–Woods number. *There are 16 partially ordered sets with four unlabeled elements. 16 is the only numb ...

Fifteenth Annual Collection
In music, a fifteenth or double octave, abbreviated ''15ma'', is the interval between one musical note and another with one-quarter the wavelength or quadruple the frequency. It has also been referred to as the bisdiapason. The fourth harmonic, it is two octaves. It is referred to as a fifteenth because, in the diatonic scale, there are 15 notes between them if one counts both ends (as is customary). Two octaves (based on the Italian word for eighth) do not make a sixteenth, but a fifteenth. In other contexts, the term ''two octaves'' is likely to be used. For example, if one note has a frequency of 400  Hz, the note a fifteenth above it is at 1600 Hz (''15ma'' ), and the note a fifteenth below is at 100 Hz (''15mb'' ). The ratio of frequencies of two notes a fifteenth apart is therefore 4:1. As the fifteenth is a multiple of octaves, the human ear tends to hear both notes as being essentially "the same", as it does the octave. Like the octave, in ...

Thirteenth Annual Collection
In music or music theory, a thirteenth is the note thirteen scale degrees from the root of a chord and also the interval between the root and the thirteenth. The thirteenth is most commonly major or minor . A thirteenth chord is the stacking of six (major or minor) thirds, the last being above the 11th of an eleventh chord. Thus a thirteenth chord is a tertian (built from thirds) chord containing the interval of a thirteenth, and is an extended chord if it includes the ninth and/or the eleventh. "The jazzy thirteenth is a very versatile chord and is used in many genres." Since 13th chords tend to become unclear or confused with other chords when inverted, they are generally found in root position. For example, depending on voicing, a major triad with an added major sixth is usually called a sixth chord , because the sixth serves as a substitution for the major seventh, thus considered a chord tone in such context. However, Walter Piston, writing in 1952, consider ...
