Are Aryabhata's and Galilean Relativity Equivalent?
  This paper considers the question of whether Aryabhata's direct and indirect references to relativity of motion are equivalent to Galilean Relativity. Examining verses fom different sections of the text Aryabhatiya, we show that there is explicit mention of relativity of space and motion, although there is no explicit reference to the motion being uniform.
