About This Design
I heart van der Pol T-Shirt
The van der Pol equation describes self-excited oscillations and has been used as a model of the heartbeat. It exhibits an unstable singular point at the origin, and linearisation about the origin generates unstable orbits whereas the true system behaviour converges on a closed curve that delineates the boundary between positive and negative damping (the boundary is not really heart-shaped; what can we say, we're a bunch of hopeless romantics).
Also available for dark apparel. Customisable.
