Gene Roddenberry, Galactic Quadrants from Star Trek, 2010

'"Galactic quadrants" within Star Trek are based around a meridian that runs from the center of the galaxy through Earth's solar system, which is not unlike the system used by astronomers. However, rather than have the perpendicular axis run through the Sun, as is done in astronomy, the Star Trek version runs the axis through the galactic center. In that sense, the Star Trek quadrant system is less-geocentric as a cartographical system than the standard. Also, rather than use ordinals, Star Trek designates them by the Greek letters Alpha, Beta, Gamma, and Delta.'

John Masefield, Sea Fever, 1916

I must go down to the seas again to the lonely sea and sky And all I ask is a tall ship and a star to steer her by And the wheel’s kick and the wind’s song and the white sail’s shaking And a gray mist on the sea’s face, and a gray dawn breaking.

I must go down to the seas again for the call of the running tide Is a wild call and a clear call That may not be denied And all I ask is a windy day with the white clouds flying And the flung spray and the blown spume and the sea-gulls crying.

I must go down to the seas again to the vagrant gypsy life To the gull’s way and the whale’s way where the wind’s like a whetted knife And all I ask is a merry yarn from a laughing fellow-rover And quiet sleep and a sweet dream when the long trick’s over.

William Shatner, "Gorn Fight Scene," Arena, Star Trek, January 19, 1967

Perhaps the greatest fight scene ever. 

Sherry Jackson, as Andrea in "What are Little Girls Made Of?" Star Trek, 1966

If Wikipedia does nothing else, it certainly provides an interesting forum for conceptual and realistic juxtaposition. This list of materials includes around one hundred utopian (fictitious) elements. Among my favorite are those I have encountered myself in reading and in film, such as:

_

This list appeals to me on several levels, a main one of which includes the etymology of unobtainium and the fact that the Book of Mormon is just as fictitious as the Lord of the Rings.
