Input: Read this: Mach argued that, in effect, the water experiment in an otherwise empty universe would remain flat. But if another object were introduced into this universe, perhaps a distant star, there would now be something relative to which the bucket could be seen as rotating. The water inside the bucket could possibly have a slight curve. To account for the curve that we observe, an increase in the number of objects in the universe also increases the curvature in the water. Mach argued that the momentum of an object, whether angular or linear, exists as a result of the sum of the effects of other objects in the universe (Mach's Principle).
Question: The Mach argument is called what?

Output: Mach's Principle

Input: Read this: Over the years the city has been home to people of various ethnicities, resulting in a range of different traditions and cultural practices. In one decade, the population increased from 427,045 in 1991 to 671,805 in 2001. The population was projected to reach 915,071 in 2011 and 1,319,597 by 2021. To keep up this population growth, the KMC-controlled area of 5,076.6 hectares (12,545 acres) has expanded to 8,214 hectares (20,300 acres) in 2001. With this new area, the population density which was 85 in 1991 is still 85 in 2001; it is likely to jump to 111 in 2011 and 161 in 2021.

Input: Read this: There have been instances where a country's government bans a movie, resulting in the spread of copied videos and DVDs. Romanian-born documentary maker Ilinca Calugareanu wrote a New York Times article telling the story of Irina Margareta Nistor, a narrator for state TV under Nicolae Ceausescu's regime. A visitor from the west gave her bootlegged copies of American movies, which she dubbed for secret viewings through Romania. According to the article, she dubbed more than 3,000 movies and became the country's second-most famous voice after Ceausescu, even though no one knew her name until many years later.
