The last letter of the Greek alphabet (Ω, ω), often used to represent the end or final element of something. In science, represents various physical quantities.
From Greek 'ō mega' meaning 'great O' (as opposed to 'omicron' meaning 'little o'). Adopted into scientific and religious contexts to represent finality, completion, or important physical constants.
Omega's pairing with alpha ('alpha and omega') to mean 'beginning and end' comes from Christian tradition, specifically the Book of Revelation. In physics, omega represents angular frequency, showing how ancient letters continue to serve modern science as precise symbols.
