This also functions as a light meter for analog photographing. There are light meter apps on smart phones, but it is fun to measure through a lighter/simpler equipment.
I’d like to recommend Prof Chern’s course on Discrete Differential Geometry https://cseweb.ucsd.edu/~alchern/teaching/cse270_wi24/. The lecture slide on Exterior Calculus includes many good illustrations of differential…
