Inspired by [url=https://twitter.com/fermatslibrary/status/1569306591676997634]this tweet from Fermat's Library[/url], the claim is made that "If you put a spherical loaf of bread through a bread slicer [with equal slice thicknesses], then each slice comes out with equal crust."[br]Calculus proof provided with with the tweet.[br][br]This visualization maybe doesn't illuminate the conclusion as much as I had hoped it would, but it was fun to create. "Un-revolving" the surface by dragging [math]\theta[/math] to a small value such as 45° may make it easier to visually judge whether each slice appears to have the same surface area.
