Because it is mentioned every now and then in physics; "I can't read this it's in Greek!" This article needs a tag for improvement or to notify the user opening the page it is not meant to be understood by the layman. There might as well not be any text on this page and just equations; one blue link after another after another after another... Wikipedia is here to define and document things NOT to be a search engine! Lazy!
