The omicron ( Greek neuter Όμικρον , "small O", in short, [compare also Omega ]; uppercase Ο, minuscule ο) is the 15th letter of the Greek alphabet and has the numerical value 70 according to the Milesian system .
origin
The sign comes from the Phoenician consonant Ajin , to which the Greeks gave the vowel value "o". It is one of the few letters in which the Greeks did not adopt the Semitic letter name. The Greeks later expanded their alphabet to include several additional letters, the last of which was the Omega (Greek: capital O). From the omicron, the Etruscan script developed the Latin O , from which the Greek letter name was dropped.
use
In mathematics, a capital O ( ) was used by Paul Bachmann in 1894 to describe the magnitude of a function. Today the sign is known as one of the Landau symbols and is sometimes understood as an omicron.
