The eigenvalue spectrum of the Laplace operator (and its negative) is of fundamental importance in mathematics and physics. In this column, the lowest eigenvalues of a fractal 2D drum are calculated using a finite element discretization. The corresponding eigenfunctions and their gradients are visualized. The cumulative number of the first 1000 eigenvalues is calculated and compared with Weyl's asymptotic formula.
