It is more like saying 1/∞ = 0. "Translations are rotations around infinity" is what you get if you compactify the real plane with projective geometry, 1/∞ = 0

It is more like saying 1/∞ = 0. "Translations are rotations around infinity" is what you get if you compactify the real plane with projective geometry, 1/∞ = 0 is what you get when you close the complex field with an holomorphic-friendly point at infinity.
