  "abstract": "Inspired by the polymath Abraham Ibn Ezra (1089-1167) who approximated π by 20/9 times the square-root of 2, and contemporary scholar, RSJ Reddy, who gave (14-sqrt(2))/4, we point out that both of these approximations are optimal in some sense, and we generate many other ones that are even more optimal, albeit not as nice.",
