In this talk, aimed at non-specialists, I’ll describe the geometric questions in the 19th century that led to the geometric theory of residual intersections, from oddities such as “How many conics in the plane are tangent to 5 given conics?” to central topics such as the Riemann-Roch theorem and the classification of space curves. I’ll then explain how the theory was refined in algebra, and point to some open problems.
