Roman numerals are still being used...
On cornerstones and gravestones,
For pagination at the beginning
of a book,
On watches and clock-faces,
To represent the charge on an
ion in chemistry,
For expressing the luminosity
class of stars,
To represent the order of discovery
of satellites,
For expressing coagulation
factors in physiology,
To designate the height of
mountains in surveying,
For specifying generations in
a pedigree,
To enumerate the items in a list.
