To rebuild Notre-Dame, they would not need stronger stone. They would need . My proposal: inject a viscoelastic polymer (a modern physics material) into the ancient joints. This would raise (c) by a factor of 10, pushing the system from underdamped ((\Delta < 0)) to overdamped ((\Delta > 0)).

I grabbed my math notebook. I modeled a single limestone voussoir (a wedge-shaped stone in the arch) as a : To rebuild Notre-Dame, they would not need stronger stone

"The cathedral didn't burn," I whispered. "It oscillated to death." The next day, Monsieur Delacroix received a 14-page email from me at 3:00 AM. Subject line: "The general solution to Notre-Dame." To rebuild Notre-Dame
