Encyclopædia:

Entries are in an alphabetical order and if there is an abbreviation for a given term it is in parentheses after the term. Greek letters are marked with their name in [ ]-brackets (such as [omega]).
(For Finnish readers: the usage of commas and decimal points is international; i.e.: there is a full stop between integer and decimal parts of a number, and a comma separating thousands, millions, etc.)
