- In mathematical logic, a universal quantification is a type of quantifier, a logical constant which is interpreted as “given any”, “for all”, or “for any”. It expresses that a predicate can be satisfied by every member of a domain of discourse. In other words, it is the predication of a property or relation to every member of the domain. It asserts that a predicate within the scope of a universal quantifier is true of every value of a predicate variable.

The Chinatown centered on Grant Avenue and Stockton Street in San Francisco, California, (Chinese: 唐人街; pinyin: tángrénjiē; Jyutping: tong4 jan4 gaai1) is the oldest Chinatown in North America and one of the largest Chinese enclaves outside Asia. It is also the oldest and largest of the four notable Chinese enclaves within San Francisco. Since its establishment in the early 1850s, it has been important and influential in the history and culture of ethnic Chinese immigrants in North America.
