Omega (uppercase Ω, lowercase ω) is the 24th and last letter of the Greek alphabet.[1] In the Greek numeric system, it has a value of 800. Pronounced [ɔ:] or 'aw' as in 'raw'.[2][3]
Symbol uppercase Ω
Astronomy
- Density of the universe, also referred to as the cosmological density parameter. with components of mass density, ΩM, and vacuum energy density, ΩL.[4][5][6]
Chemistry
- Designation for the last carbon on the chain in a fatty acid
Electricity
- Ohm: SI unit of electrical resistance
- Siemens (unit), abbreviated S, is the reciprocal of the ohm.
Mathematics
- Omega constant (Lambert’s W function)[7]
- Chaitin’s constant: the probability that a randomly selected valid program string is interpreted by a halting
term[8]
- Calculus: a 2-D region
- A theoretical measure of the execution of an algorithm, (e.g. required time or memory) given the problem size n (e.g. the number of items).[9]
- Stochastic process[10]
Meteorology
- Used to designate vertical motion in the atmosphere[11]
Statistics
- Sample space
- Set of possible outcomes
Literary
- End or last thing in a series[12]
Physics
- Solid angle or rate of precession in a gyroscope[13]
- Omega baryons (particle physics)
- Negatively charged elementary particle with a mass 3270 times the mass of an electron.[14]
- Omega minus b: a very short-lived unstable meson with mass 1532 times the mass of an electron (aka omega meson)[15]
Symbol lowercase ω
Mathematics
- The set of all natural numbers[16]
Physics
- Angular frequency
