The Fin is the name of two characters from Marvel Comics. The Golden Age Fin has elements of both the swashbuckling pirate and superhero genres.
The Fin first appeared in Daring Mystery Comics #7-8, (April 1941, Jan.1942), and was created by Bill Everett. Decades later, a simulacrum of the Fin briefly appeared, along with simulacra of the Blazing Skull, the Patriot, and the Golden Age Angel and Vision, to aid the superhero team the Avengers in The Avengers #97 (March 1972).
In 2004 the Fin was revived by Marvel Comics and appeared as an ally of the Invaders in that team's series The New Invaders #2-3 (Nov.-Dec. 2004), #6 (March 2005), and #8-9 (May–June 2005). He was in the (unfinished) miniseries All-Winners Squad: Band of Heroes as a member of the Crazy Sues, a unit of Allied men with special abilities during World War II.
The Fin received an entry in The Official Handbook of the Marvel Universe Golden Age (2004).
"Fin" is a song from British rock band Supergrass' 2005 album, Road to Rouen. It was released on 2 January 2006 as the third single from the album (see 2006 in music). It was only available as a 7" and digital download, and only charted in the UK at #111.
The song is a very slow and gentle ballad, with 'watery' effects over the vocals.

In the study of heat transfer, fins are surfaces that extend from an object to increase the rate of heat transfer to or from the environment by increasing convection. The amount of conduction, convection, or radiation of an object determines the amount of heat it transfers. Increasing the temperature gradient between the object and the environment, increasing the convection heat transfer coefficient, or increasing the surface area of the object increases the heat transfer. Sometimes it is not feasible or economical to change the first two options. Thus, adding a fin to an object, increases the surface area and can sometimes be an economical solution to heat transfer problems.
To create a tractable equation for the heat transfer of a fin, many assumptions need to be made:
Fin is a surface used to produce lift and thrust or to steer while traveling in water, air, or other fluid media.
