Selangor ( /səˈlæŋə/) also known by its Arabic honorific, Darul Ehsan, or "Abode of Sincerity") is one of the 13 states of Malaysia. It is on the west coast of Peninsular Malaysia and is bordered by Perak to the north, Pahang to the east, Negeri Sembilan to the south and the Strait of Malacca to the west. It surrounds the federal territories of Kuala Lumpur and Putrajaya, both of which were once under Selangor's sovereignty.

The state capital is Shah Alam, the first city in Selangor, and the royal capital is Klang. Another major urban centre is Petaling Jaya which was awarded city status on June 20, 2006. Selangor is one of only two Malaysian states with more than one city; the other is Sarawak. Selangor has the largest city in Malaysia and it is growing rapidly due to modernization in the Klang Valley.^{[citation needed]}

Selangor is the richest state in Malaysia in terms of gross domestic product (GDP) per capita. This state is also the most developed in Malaysia with good infrastructure such as highways and transport. The state also has the largest population in Malaysia, with a high standard of living and the state's poverty rate is the lowest in the country.

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.
