We are all familiar with the sounds emitted by rivers, waterfalls, dripping taps and boiling kettles. Osborne Reynolds and William Bragg are among the late nineteenth and early twentieth century physicists who attempted to explain the origins of these sounds (but only with limited success). This seminar will describe the currently-accepted explanation of these sounds. It will also describe the reverse process where sound is fed into a liquid; at large insonating sound pressures light is emitted (sonoluminescence). Live and videoed demonstrations will be included
