The Gaussian integral looks innocent, a smooth bell-shaped function stretching to infinity, yet it cannot be solved by elementary methods, only by understanding geometry, dimensional extension, and invariance. By squaring the integral, rotating space, and letting symmetry do the work, a problem that see
