2 unusual facts about van der Pol


Hidden oscillation

Classical attractors in the well-known dynamical systems of Van der Pol, Beluosov–Zhabotinsky, Lorenz, Rössler, Chua and many others are self-excited attractors and can be obtained numerically, with relative ease, by standard computational procedures described above.

Duncan Lunan proposed the radio echoes observed by Størmer and Van der Pol in 1928 might have been transmissions from a Bracewell probe, an artifact of aliens trying to communicate with us by bouncing back our own signals.
