Abstract: The human ear has discovered a new phenomenon in quantum mechanics. Two reservoirs of superfluid helium, connected only by tiny holes, oscillate when they are pumped to different pressures. This effect is expected, and is analogous to the familiar Josephson effect in electronics, but in the superfluid system it has been exceptionally hard to demonstrate.
