Is February 22, 2010 the Birthday of  "Hella" ?

The official petition to establish "hella" as the SI prefix was filed.



Austin Sendek, a physics grad student at UC Davis has asked the English slang term "hella" be elevated to proper noun status as the name of a very large number.

Traditionally, the SI , or the International System of Units, has adopted the last names of outstanding scientists for unit nomenclature.  Sendek will insist that 10^27 is a "helluva" large number.
