Big Apple
Although the history of "Big Apple " was once thought a mystery, a clearer picture of the term's history has emerged due to the work of amateur etymologist Barry Popik, and Gerald Cohen of Missouri University of Science and Technology. A number of false theories had previously existed, including a claim that the term derived from a woman named Eve who ran a brothel in the city. This was subsequently exposed as a hoax.
Caput Mundi
New York City, the most populous city in the United States, is sometimes described by the Latin phrase ""Novum Caput Mundi"" ("New Capital of the World"); or more commonly by the English phrase, "Capital of the World". A leading global city, New York exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term "New York minute". Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world, despite not being the modern capital of the United States or even of New York State. As many as 800 languages are spoken in New York City, making it the most linguistically diverse city in the world.
