The figure is sometimes called "Boyle's perpetual motion scheme" (in honor of Robert Boyle (1627-1691)), the "perpetual vase" or "perpetual goblet". It was discussed by Denis Papin (1647-1712) in the Philosophical Transactions for 1685. It was even accepted by John Bernoulli (1667-1748). Some commentators call it the "hydrostatic paradox". Some confuse the hydrostatic system with a capillary system.
