Equiangular Surfaces, Self-Similar Surfaces, and the Geometry of Seashells
Boyadzhiev, Khristo N.
College Mathematics Journal, v38 n4 p265-271 Sep 2007
Logarithmic spirals are among the most fascinating curves in the plane, being the only curves that are equiangular, and the only ones that are self-similar. In this article, we show that in three dimensions, these two properties are independent. Although there are surfaces that have both properties, there are some that are equiangular, but not self-similar; and some that are self-similar, but not equiangular.
