- Herman Melville (Wikipedia)
Herman Melville (born Melvill; August 1, 1819 – September 28, 1891) was an American novelist, short story writer, and poet of the American Renaissance period. Among his best-known works are Moby-Dick (1851); Typee (1846), a romanticized account of his experiences in Polynesia; and Billy Budd, Sailor, a posthumously published novella. Although his reputation was not high at the time of his death, the 1919 centennial of his birth was the starting point of a Melville revival, and Moby-Dick grew to be considered one of the great American novels.
- Natural number (Wikipedia)
In mathematics, the natural numbers are the numbers 1, 2, 3, etc., possibly including 0 as well. Some definitions, including the standard ISO 80000-2, begin the natural numbers with 0, corresponding to the non-negative integers 0, 1, 2, 3, …, whereas others start with 1, corresponding to the positive integers 1, 2, 3, … Texts that exclude zero from the natural numbers sometimes refer to the natural numbers together with zero as the whole numbers, while in other writings, that term is used instead for the integers (including negative integers). In common language, particularly in primary school education, natural numbers may be called counting numbers to intuitively exclude the negative integers and zero, and also to contrast the discreteness of counting to the continuity of measurement—a hallmark characteristic of real numbers.
