Zeta is the sixth letter of the Greek alphabet. In the system of Greek numerals,it has a value of 7 rather than 6 because the letter digamma (also called 'stigma' as a Greek numeral) was originally in the sixth position in the alphabet. The lower case letter is commonly used in mathematics,materials and earth sciences. The Greek alphabet has an important role in the nomenclature of astronomical bodies and subatomic particles | |
