In geometry, the Whitney umbrella (or Whitney's umbrella, named after American mathematician Hassler Whitney, and sometimes called a Cayley umbrella) is a specific self-intersecting ruled surface placed in three dimensions. It is the union of all straight lines that pass through points of a fixed parabola and are perpendicular to a fixed straight line which is parallel to the axis of the parabola and lies on its perpendicular bisecting plane. (Wikipedia).

Resolution in characteristic 0 using weighted blowing up. - Abramovich - Workshop 2 - CEB T2 2019
Dan Abramovich (Brown University) / 28.06.2019 Resolution in characteristic 0 using weighted blowing up. Given a variety, one wants to blow up the worst singular locus, show that it gets better, and iterate until the singularities are resolved. Examples such as the whitney umbrella show

algebraic geometry 34 Blowing up a point
This lecture is part of an online algebraic geometry course, based on chapter I of "Algebraic geometry" by Hartshorne. It covers blowing up a point of affine space, and gives some examples of using this to resolve singularities of plane curves.
