Numeral (linguistics)

In linguistics, a numeral is a member of a word class (or sometimes even a part of speech) designating numbers, such as the English word 'two' and the compound 'seventy-seven'.

Identifying numerals

Numerals may be attributive, as in two dogs, or pronominal, as in I saw two (of them).

Many words of different parts of speech indicate number or quantity. Quantifiers do not enumerate, or designate a specific number, but give another, often less specific, indication of amount. Examples are words such as every, most, least, some, etc. There are also number words which enumerate but are not a distinct part of speech, such as 'dozen', which is a noun, 'first', which is an adjective, or 'twice', which is an adverb. Numerals enumerate, but in addition have distinct grammatical behavior: when a numeral modifies a noun, it may replace the article: the/some dogs played in the park → twelve dogs played in the park. (Note that *dozen dogs played in the park is not grammatical, so 'dozen' is not a numeral.)

Zero (Yeah Yeah Yeahs song)

"Zero" is a song by American indie rock band Yeah Yeah Yeahs, released as the lead single from their third studio album, It's Blitz! (2009). The song received critical acclaim from music critics for its production, and was named the best track of 2009 by both NME and Spin magazines.

The single had minor commercial success, peaking at numbers four and eighteen on the Billboard Alternative Songs and Hot Dance Singles Sales charts, as well as number forty-nine on the UK Singles Chart. A music video for the single, which shows lead singer Karen O walking the streets of San Francisco at night, was released in March 2009.

Critical reception

"Zero" received acclaim from music critics. Paula Carino of AllMusic described the song as "an exhilarating and wide-open expanse of pure electro-pop". Mary Bellamy of Drowned in Sound viewed the track as "the call to arms of a band who desperately want to teleport the refugees of fashion-fizzled pop, the hippest of hipsters and the weirdest outsiders to the dancefloor of their sweaty spaceship", stating it is "perhaps one of the band's finest moments ever committed to tape."

Mazda Wankel engine

The Mazda Wankel engines (a type of rotary combustion engine) comprise a family of car engines derived from experiments in the early 1960s by Felix Wankel, a German engineer. Over the years, displacement has been increased and turbocharging has been added.

Wankel engines can be classified by their geometric size in terms of radius (rotor center to tip distance, also the median stator radius) and depth (rotor thickness), and offset (crank throw, eccentricity, also 1/4 the difference between stator's major and minor axes). These metrics function similarly to the bore and stroke measurements of a piston engine. Displacement is 3√3radius·offset·depth, multiplied with the number of rotors (note that this only counts a single face of each rotor as the entire rotor's displacement). Nearly all Mazda production Wankel engines share a single rotor radius, 105 mm (4.1 in), with a 15 mm (0.6 in) crankshaft offset. The only engine to diverge from this formula was the rare 13A, which used a 120 mm (4.7 in) rotor radius and 17.5 mm (0.7 in) crankshaft offset.
