I really don't understand this: "Just as the perimeter of a circle is 2π, the perimeter of this curve is 2ϖ".

Well, technically, the perimeter of a circle is 2π time its radius, so I expect the lemniscate's perimeter is 2ϖ times "some radius". What is it? On a circle it's obvious but not on an 8-shaped curve.
