The Hebrew letter א (aleph), just like Greek letter α, Latin a and Cyrillic а, was derived from the ancient Phoenician letter 𐤀 (ʾālep) which, in turn, was derived from 𓃾, the Egyptian hieroglyph of an ox’s head.
El Aleph (The Aleph) is a short story by Jorge Luis Borges. In this story, The Aleph is a point in space that contains all other points. In mathematics, the aleph numbers are a sequence of numbers used to represent the cardinality (or size) of infinite sets. The smallest infinite cardinal number is called ℵ0 (aleph-naught or aleph-null).
