He showed how to make droplets of oil bounce on an oil surface\, spawning a renewed interest in the net forces between oscillating systems. Bouncing droplets are governed by the ordinary equations of Newtonian mec hanics\, yet experimentally their motion mimics the known equations of spe cial relativity\, electromagnetism\, and quantum mechanics. I will show wh y this is the case\, in an idealised system where the pumping acceleration can be neglected. I will then briefly discuss my ongoing research in a re lated system in superfluid helium\, where pumping is superfluous and the p redictions may be tested against experiment.\n\nIn order to maintain your interest\, and to pay respect to Yves\, I will give an interpretation of h is work which is controversial. If his results had been known 100 years ag o\, they would probably have changed the debate\, from 1905 to 1922\, betw een Einstein and Lorentz on how to interpret the equations of special rela tivity.\n LOCATION:https://researchseminars.org/talk/QMFNoT/8/ END:VEVENT END:VCALENDAR
