The Crown of Aragon (Aragonese: Corona d'Aragón, Catalan: Corona d'Aragó, Latin: Corona Aragonum, Spanish: Corona de Aragón) was a personal and dynastic union of multiple titles and states in the hands of the King of Aragon. At the height of its power in the 14th and 15th centuries, the Crown of Aragon was a thalassocracy (a state with primarily maritime realms) controlling a large portion of the present-day eastern Spain and southwestern France, as well as some of the major islands and mainland possessions stretching across the Mediterranean as far as Greece. The component realms of the Crown were not united politically except at the level of the king, who ruled over each autonomous polity according to its own laws, raising funds under each tax structure, dealing separately with each cortes. Put in contemporary terms, the disparate lands of Aragon functioned more as a confederacy of cultures rather than as a single country. In this sense, the larger Crown of Aragon must not be confused with one of its constituent parts, the Kingdom of Aragon, from which it takes its name.

Aragon ( /ˈærəɡɒn/ or /ˈærəɡən/), also known in Spanish and Aragonese as Aragón ([aɾaˈɣon]) and in Catalan as Aragó ([əɾəˈɣo] or [aɾaˈɣo]), is a modern autonomous community in Spain, coextensive with the medieval Kingdom of Aragon. Located in northeastern Spain, the Aragonese autonomous community comprises three provinces (from north to south): Huesca, Zaragoza, and Teruel. Its capital is Zaragoza (also called Saragossa in English). The current Statute of Autonomy declares Aragon a nationality of Spain.

Aragon's northern province of Huesca borders France and is positioned in the middle of the Pyrenees. Within Spain, the community is flanked by Catalonia on the east, Valencia and Castile–La Mancha to the south, and Castile and León, La Rioja, and Navarre to the west.

Covering an area of 47,719 km² (18,424 sq mi), the region's terrain ranges diversely from permanent glaciers to verdant valleys, rich pasture lands and orchards, through to the arid steppe plains of the central lowlands. Aragon is home to many rivers—most notably, the river Ebro, Spain's largest river in volume, which runs west-east across the entire region through the province of Zaragoza. It is also home to the Aneto, the highest mountain in the Pyrenees.

3-2-1 Contact is an American science educational television show that aired on PBS from 1980 to 1988, and an adjoining children's magazine. The show, a production of the Children's Television Workshop, teaches scientific principles and their applications. Dr. Edward G. Atkins, who was responsible for much of the scientific content of the show, felt that the TV program wouldn't replace a classroom but would open the viewers to ask questions about the scientific purpose of things.

3-2-1 Contact was the brainchild of Samuel Y. Gibbon, Jr., who had been the executive producer of The Electric Company for CTW from 1971 to 1977. (Gibbon actually left CTW before Contact's production began, though he was still credited as "Senior Consultant.")

The first season of 65 programs began airing January 14, 1980 on select PBS member stations; it featured a cast of three college students who discussed science in an on-campus room known as the Workshop. The first season came to an end on April 11, 1980, but funds for more episodes were not sufficient until 1982.
