In the overdamped regime, the general solution becomes:

In his office, he showed me a photograph of the Beauvais Cathedral choir, which collapsed in 1284. "They built it too high," he said. "They forgot that the force ( F ) on a pillar is not just the weight above it. It is the integral of stress over the surface. They forgot the math." Sujet Grand Oral Maths Physique

The fire didn’t burn the spire down. The fire shook the spire apart. The vibrations from the thermal pulses amplified until the amplitude went to infinity in theory—but in reality, until the mortar turned to dust and the keystone slipped. In the overdamped regime, the general solution becomes:

I shouted at my screen. My mother ran in. "Léa? What is it?" It is the integral of stress over the surface

This is the story of how I used a second-order differential equation to prove that the impossible could be rebuilt. Three weeks before the fire, I had failed my mock physics exam. My teacher, Monsieur Delacroix, had drawn a simple arch on the blackboard. "Explain the stability of the Romanesque vault," he said.

[ \frac{d^2x}{dt^2} + \omega^2 x = 0 ]

[ \frac{\partial T}{\partial t} = \alpha \nabla^2 T ]
