Title: Pascal's Hexagrammum Mysticum: Solving a 400-Year-Old Geometry Problem

Abstract: In 1639, the 16 year old Blaise Pascal proved his Hexagrammum Mysticum Theorem which provides a straightedge construction to test whether 6 points in the plane lie on a conic. This naturally led to the question of whether there is a straightedge construction which tests whether there is a cubic curve through 10 given points in the plane. I will discuss my joint solution with former Queen's mathematics undergraduate Dr. Will Traves (US Naval Academy) to this problem explaining some of the history.
