In predicate logic, an existential quantification is the predication of a property or relation to at least one member of the domain. It is denoted by the logical operator symbol ∃ (pronounced "there exists" or "for some"), which is called the existential quantifier. Existential quantification is distinct from universal quantification ("for all"), which asserts that the property or relation holds for any members of the domain.

Symbols are encoded U+2203 ∃ there exists (HTML: ∃ ∃ as a mathematical symbol) and U+2204 ∄ there does not exist (HTML: ∄).

Consider a formula that states that some natural number multiplied by itself is 25.

0·0 = 25, or 1·1 = 25, or 2·2 = 25, or 3·3 = 25, and so on.

This would seem to be a logical disjunction because of the repeated use of "or". However, the "and so on" makes this impossible to integrate and to interpret as a disjunction in formal logic. Instead, the statement could be rephrased more formally as

For some natural number n, n·n = 25.

This is a single statement using existential quantification.

Larry King (born November 19, 1933) is an American television and radio host whose work has been recognized with awards including two Peabodys and ten Cable ACE Awards. He began as a local Florida journalist and radio interviewer in the 1950s and 1960s and became prominent as an all-night national radio broadcaster starting in 1978. From 1985-2010, he hosted the nightly interview TV program Larry King Live on CNN.

King was born Lawrence Harvey Zeiger in Brooklyn, New York City, to an Austrian immigrant Edward Zeiger, a restaurant owner and defense plant worker, and his wife Jennie Gitlitz, a garment worker, who emigrated from Belarus. King grew up in a religiously observant Jewish home, but in adulthood became an agnostic.

King's father died at 44 of heart disease, and his mother had to go on welfare to support her two sons. His father's death greatly affected King, and he lost interest in school. After graduating from high school, he worked to help support his mother. From an early age, however, he had wanted to go into radio. King is a fan of the Los Angeles Dodgers.
