Assuming for the sake of argument that a pringle shaped potato chip has a constant negative curvature, (which according to https://math.stackexchange.com/a/617610/88985 it is not )
see also picture at The shape of Pringles potato chip
- How can we measure its curvature?
Assuming our ony measuring tool is an Vernier caliper ( https://en.wikipedia.org/wiki/Calipers#Vernier_caliper ) (so we cannot measure along a surface)
- Can we still measure the curvature ?
and to end:
- Can we proof or disproof that a pringle has a constant curvature?
