OSCILLATIONS AND ONSET OF CHAOS IN A DRIVEN NONLINEAR OSCILLATOR WITH POSSIBLE ESCAPE TO INFINITY

This is a brief account of various aspects of the evolutionary pattern of a driven nonlinear oscillator. The model was proposed a century ago by Helmholtz in order to explain the combinational tones in the drumskin, and more recently, by J. M. T. Thompson, to study ship stability against waves in windy situations.
