Asterisk Asterisk An asterisk (*); from Late Latin , from Ancient Greek , "asteriskos", "little star") is a typographical symbol or glyph. It is so called because it resembles a conventional image of a star. Computer scientists and mathematicians often vocalize it as star (as, for example, in "the A* search algorithm" or "C*-algebra"). In English, an asterisk is usually five-pointed in sans-serif typefaces, six-pointed in serif typefaces, and six- or eight-pointed when handwritten. It is often used to censor offensive words, and on the Internet, to indicate a correction to a previous message. The asterisk is derived from the need
Typographical Number Theory Typographical Number Theory Typographical Number Theory (TNT) is a formal axiomatic system describing the natural numbers that appears in Douglas Hofstadter's book "Gödel, Escher, Bach". It is an implementation of Peano arithmetic that Hofstadter uses to help explain Gödel's incompleteness theorems. Like any system implementing the Peano axioms, TNT is capable of referring to itself (it is self-referential). TNT does not use a distinct symbol for each natural number. Instead it makes use of a simple, uniform way of giving a compound symbol to each natural number: The symbol S can be interpreted as "the successor of", or "the number
