Correlation spectroscopy is one of several types of two-dimensional nuclear magnetic resonance (NMR) spectroscopy or 2D-NMR.
This type of NMR experiment is best known by its acronym, COSY.
Other types of two-dimensional NMR include J-spectroscopy, exchange spectroscopy (EXSY), Nuclear Overhauser effect spectroscopy (NOESY), total correlation spectroscopy (TOCSY) and heteronuclear correlation experiments, such as HSQC, HMQC, and HMBC.
Two-dimensional NMR spectra provide more information about a molecule than one-dimensional NMR spectra and are especially useful in determining the structure of a molecule, particularly for molecules that are too complicated to work with using one-dimensional NMR.
The first two-dimensional experiment, COSY, was proposed by Jean Jeener, a professor at Université Libre de Bruxelles, in 1971.
This experiment was later implemented by Walter P. Aue, Enrico Bartholdi and Richard R. Ernst, who published their work in 1976. 
To understand the nature of four-dimensional space, a device called "dimensional analogy" is commonly employed.
Dimensional analogy is the study of how ("n" − 1) dimensions relate to "n" dimensions, and then inferring how "n" dimensions would relate to ("n" + 1) dimensions.
Dimensional analogy was used by Edwin Abbott Abbott in the book "Flatland", which narrates a story about a square that lives in a two-dimensional world, like the surface of a piece of paper.
From the perspective of this square, a three-dimensional being has seemingly god-like powers, such as ability to remove objects from a safe without breaking it open (by moving them across the third dimension), to see everything that from the two-dimensional perspective is enclosed behind walls, and to remain completely invisible by standing a few inches away in the third dimension.
By applying dimensional analogy, one can infer that a four-dimensional being would be capable of similar feats from our three-dimensional perspective.
Rudy Rucker illustrates this in his novel "Spaceland", in which the protagonist encounters four-dimensional beings who demonstrate such powers. 
Maureen Ryan of "Chicago Tribune" criticized the character portrayed by Jamil Walker Smith: "perhaps the intention was to have Master Sergeant Ronald Greer come off as a rebellious yet courageous hothead but the character is just a one-dimensional, obnoxious idiot".
Brian J. Smith (who portrays the character of Matthew Scott) from the series called Jamil's Greer his favorite on the series; likewise, Jamil stated his favorite character was that of Scott.
The character is compared to Eric Bana's character "Hoot" in "Black Hawk Down".
Kevin Cole of Fused Film was very positive of Jamil's contribution to SGU: "He is a cowboy that will bring a lot of interesting development throughout the series.
Walker really makes him work with casual smiles and little subtleties and nuances that this guy should have."
Two-dimensional nuclear magnetic resonance spectroscopy (2D NMR) is a set of nuclear magnetic resonance spectroscopy (NMR) methods which give data plotted in a space defined by two frequency axes rather than one.
Types of 2D NMR include correlation spectroscopy (COSY), J-spectroscopy, exchange spectroscopy (EXSY), and Nuclear Overhauser effect spectroscopy (NOESY).
Two-dimensional NMR spectra provide more information about a molecule than one-dimensional NMR spectra and are especially useful in determining the structure of a molecule, particularly for molecules that are too complicated to work with using one-dimensional NMR.

From 2010-2012, Macken played the recurring character of Gwaine (loosely based on the image of Gawain) in the BBC One TV series "Merlin".
He has reprised the role in four episodes of the third series and all episodes of the fourth and fifth series.
Gwaine is portrayed as a care-free and laid back man who provides a lot of comic relief for the show, but, remains brave and loyal throughout his time on the show.
In the final episode his character perished after being tortured with a snake by Morgana (Played by Katie McGrath).
His friend, Percival arrives to save him, but, is too late and Gwaine's final thought is that he failed after giving in to the torture and revealing the injured king's destination.
Gwaine was described as a man who "deep down respects honour, valour and camaraderie above everything else."
