Split Second (1992 film)

Split Second is a 1992 British science fiction film starring Rutger Hauer, Kim Cattrall, and Neil Duncan. The film is directed by Tony Maylam and Ian Sharp.

Plot

In the year 2008, heavy rainfall has flooded large areas of London. Rookie police officer Dick Durkin (Duncan) is assigned to partner Harley Stone (Hauer), a burnt-out and highly cynical homicide detective who, according to his commanding officer, survives on "anxiety, coffee and chocolate" after being unable to prevent the murder of his partner by a serial killer several years previously. Now however, the murders have begun again and Stone and Durkin are assigned the case. After investigating the scenes of several killings, they appear no closer to identifying the killer, with their only clues being that the murders seem to be linked to the lunar cycle, and that the killer has multiple recombinant DNA strands, having absorbed the DNA of the victims.

Finally, after Stone's girlfriend Michelle (Cattrall) is kidnapped, the detectives track the killer deep into the flooded and disused London Underground system and discover the truth: the killer is not human. It's a horrific and possibly demonic form of life that is fast, savage, bloodthirsty and fixated upon killing Stone just as it previously killed his partner. In fact, as the movie progresses, each killing and "appearance" of the monster is an attempt to lure Stone closer and closer.

Second (parliamentary procedure)

In deliberative bodies a second to a proposed motion is an indication that there is at least one person besides the mover that is interested in seeing the motion come before the meeting. It does not necessarily indicate that the seconder favors the motion.

Purpose

The purpose of requiring a second is to prevent time being wasted by the assembly's having to dispose of a motion that only one person wants to see introduced. Hearing a second to a motion is guidance to the chair that he should state the question on the motion, thereby placing it before the assembly. It does not necessarily indicate that the seconder favors the motion.

Procedure

The seconder may state "I second the motion" or "second" without first being recognized by the chair. He may remain seated but in larger assemblies, especially in those where nonmembers may be seated in the hall, the seconder should stand. After hearing a second, the chair then states the question and the motion is placed before the assembly for discussion.

List of pitch intervals

Below is a list of intervals exprimable in terms of a prime limit (see Terminology), completed by a choice of intervals in various equal subdivisions of the octave or of other intervals.

For commonly encountered harmonic or melodic intervals between pairs of notes in contemporary Western music theory, without consideration of the way in which they are tuned, see Interval (music) § Main intervals.

Terminology

Minute and second of arc

A minute of arc (MOA), arcminute (arcmin) or minute arc is a unit of angular measurement equal to one-sixtieth (1/60) of one degree. As one degree is 1/360 of a circle, one minute of arc is 1/21600 of a circle (or, in radians, π/10800). It is used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying and marksmanship.

The number of square arcminutes in a complete sphere is approximately 148,510,660 square arcminutes.

A second of arc (arcsecond, arcsec) is 1/60 of an arcminute, 1/3,600 of a degree, 1/1,296,000 of a circle, and π/648,000 (about 1/206,265) of a radian. This is approximately the angle subtended by a U.S. dime coin (18mm) at a distance of 4 kilometres (about 2.5 mi).

To express even smaller angles, standard SI prefixes can be employed; the milliarcsecond (mas), for instance, is commonly used in astronomy.

Symbols and abbreviations

The standard symbol for marking the arcminute is the prime (′) (U+2032), though a single quote (') (U+0027) is commonly used where only ASCII characters are permitted. One arcminute is thus written 1′. It is also abbreviated as arcmin or amin or, less commonly, the prime with a circumflex over it ().

Splitting lemma

In mathematics, and more specifically in homological algebra, the splitting lemma states that in any abelian category, the following statements for a short exact sequence are equivalent.

Given a short exact sequence with maps q and r:

one writes the additional arrows t and u for maps that may not exist:

Then the following statements are equivalent:

The short exact sequence is called split if any of the above statements hold.

(The word "map" refers to morphisms in the abelian category we are working in, not mappings between sets.)

It allows one to refine the first isomorphism theorem:

the first isomorphism theorem states that in the above short exact sequence, (i.e. "C" isomorphic to the coimage of "r" or cokernel of "q")

if the sequence splits, then , and the first isomorphism theorem is just the projection onto C.

It is a categorical generalization of the rank–nullity theorem (in the form ) in linear algebra.

Proof

First, to show that (3) implies both (1) and (2), we assume (3) and take as t the natural projection of the direct sum onto A, and take as u the natural injection of C into the direct sum.

Split (bowling)

A split is a situation in ten pin bowling in which the first ball of a frame knocks down the headpin ("number 1 bowling pin") but leaves standing two or more non-adjacent groups of one or more pins. Scoring a spare in this situation is often referred to as a "killer shot".

Types

7–10 split

One of the most infamous of splits is the 7–10 split, often called "goal posts" or "bedposts", where the bowler is left with the leftmost and the rightmost pin in the back row (the number 7 and number 10) to knock down with a single ball to achieve a spare. This is also one of the most difficult splits to pick up.
