Summary
[edit]
| Description |
English: A skeleton and his master `Pi-Rat' eat slices of pizza. The pizza of the skeleton goes limp. Instead Pi-Rat manages to keep his from sagging, bending the edge. The key point is a property of invariance of the curvature of surfaces, whose theorem is attributed to C. F. Gauss, a mathematician who lived between 1700 and 1800. Gauss himself was very enthusiastic about this math result, so much so that he named it his “supercool theorem”. Our character Pi-Rat knows that for the pizza the product of the maximal curvature and the minimal curvature must be zero, so forcing the curvature to be nonzero along the edge, in other directions the curvature must be zero. And the pizza stays straight! |
