The Invention of the Decimal Point

This video about Arab numerals and the invention of the decimal point in mathematics were inexplicably more interesting than it should’ve been.  It’s also the perfect length, just long enough to be informative, not too long that my limited attention span wavered.

By the by, Arab numerals originated from India

FYI: There’s another BBC documentary, named The Story of Maths.  It’s four episodes long and the second deals with various numeral systems throughout history.  [via Reddit]
