Intrinsic Geometry of a Crookneck Squash
Chapter 1 Euclidean and Non-Euclidean Geometry r a b c d Δ₂ Δ₁ [1.9] The intrinsic geometry of the surface of a crookneck squash: geodesics are the equivalents of straight lines, and triangles formed out of them may possess an angular excess of either sign, depending on how the surface bends: ε(Δ₁) > 0 and ε(Δ₂) < 0.
A textbook diagram treats the curved surface of a crookneck squash as a geometric space, showing geodesics and two triangles with opposite angular excesses. The joke comes from applying sophisticated non-Euclidean geometry to an oddly shaped vegetable, making the squash look like an absurd mathematical object.
