Omega (uppercase Ω, lowercase ω) is the 24th and last letter of the Greek alphabet. In the Greek numeric system, it has a value of 800.
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.[1]
Chemistry
- designation for the last carbon on the chain in a fatty acid
Electricity
- ohm: SI unit of electrical resistance
Mathematics
- Omega constant (Lambert’s W function)[2]
- Chaitin’s constant: the probability that a randomly selected valid program string is interpreted by a halting
term[3]
- 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).[4]
Meterology
- Used to designate vertical motion in the atmosphere[5]
Statistics
- Sample space
- Set of possible outcomes
Literary
- End or last thing in a series[6]
Physics
- Solid angle or rate of precession in a gyroscope[7]
- Omega baryons (particle physics)
- Negatively charged elementary particle with a mass 3270 times the mass of an electron.[8]
- Omega minus b: a very short-lived unstable meson with mass 1532 times the mass of an electron (aka omega meson)[9]
