Baron Pierre Charles François Dupin (6 October 1784, Varzy, Nièvre – 18 January 1873, Paris, France) was a French Catholic mathematician, engineer, economist and politician, particularly known for work in the field of mathematics, where the Dupin cyclide and Dupin indicatrix are named after him; and for his work in the field of statistical and thematic mapping. In 1826 he created the earliest known choropleth map. (Wikipedia).

We look at some of the work of Charles Dupin, a French naval engineer and student of Monge. He made some lovely discoveries about triply orthogonal surfaces and lines of curvatures, for example confocal families of ellipses and hyperbolas. He studied conjugate directions on surfaces (going

Here we continue our study of the works of three important French differential geometers. Today we discuss G. Monge, who is sometimes called the father of the subject. He was the inventor of descriptive geometry (which he developed for military applications), and various theorems in Euclid

Paraboloids and associated quadratic forms | Differential Geometry 23 | NJ Wildberger
Paraboloids are going to play a special role in our understanding of curvature. The idea is that we are going to locally approximate a surface S near a point by a normal paraboloid---one that shares the same tangent plane, but has an axis which is perpendicular to that tangent plane. It w
