I will introduce a geometric object called a grasper, and explain how it gives rise to families of embeddings of an arc or a circle into an arbitrary manifold of any dimension. These families are detected by Goodwillie—Weiss embedding calculus, so the question of their nontriviality is reduced to algebraic topology. In dimension 3 our discussion reduces to constructions of knots using gropes/claspers.
