Mathematical 'explosions' in physical systems have been found to naturally arrange themselves into perfect geometric shapes like squares and hexagons.

The Takeaway
When certain physical equations reach a 'blow-up' point of infinite energy, you would expect total chaos. Instead, researchers proved that these singularities fix themselves into perfect polygons, revealing an eerie geometric order hidden inside the most violent moments of a system's evolution.
From the abstract
We study the blow-up behavior of solutions to the singular Liouville equation\[\Delta \tilde u+\lambda e^{\tilde u}=4\pi\alpha\delta_0\quad\text{in }B,\quad\tilde u=0\quad\text{on }\partial B,\] where $\alpha>0$, $\lambda>0$ and $B\subset\mathbb R^2$ is the unit disk. Our main results give a complete classification of all blow-up solutions and determine the exact number of solutions to the above equation. More precisely, for fixed $\alpha>0$ and $\lambda\in(0,\lambda_\alpha)$, the singular Liouv
