 Balthasar van der Pol

Balthasar van der Pol was a Dutch physicist and engineer, best known for his work in the field of nonlinear dynamics and oscillatory phenomena. Among his contributions, he is recognized for developing the Van der Pol oscillator, a nonlinear differential equation which describes self-sustaining oscillations. This oscillator is significant in the study of systems that exhibit behavior like that of biological rhythms, electrical circuits, and other physical systems.
