On a curve veering aberration
TL;DR: In this article, the Ritz-Galerkin method is applied to the classical eigenvalue problem of the free vibration of a rectangular membrane, and it is shown that the behavior of curves which approach each other and suddenly veer away may be the result of approximation in the representation of physical reality.
