The exact curve of a surface is basically a blueprint that tells it exactly how it’s going to shatter when it breaks.

Where Humpty Dumpty Breaks: Geometry-Driven Fracture in Ellipsoidal Shells

The Takeaway
By studying everything from botanical peels to the crusts of moons, scientists found that the geometry of a shell—not just the material it's made of—controls the direction and pattern of cracks. This allows researchers to predict fracture networks based purely on the shape of the object.
From the abstract
Fracture networks are ubiquitous in nature, spanning scales from millimeter-sized cracks in botanical peels to hundred-kilometer-long lineae on planetary satellites. The propagation of a crack is a complex, nonlinear phenomenon governed by the interplay of mechanical properties, rheological behavior, and system geometry. While fracture mechanics has long addressed structural failure, the relationship among fracture, elasticity, and nonlinear geometry has recently revived as a focal point in cond
