Unique long-term visibility variations are detected when the quiet Sun is observed with interferometers operating at 8 mm and 11 cm wavelength with angular resolutions of -0.5'. Quasiperiodic fluctuations in fringe amplitude are observed with periods between 20 and 30 rain, and with amplitude nulls

We are studying the quantum limit of zero sound absorption in normal 3He in which sound quanta are absorbed or emitted directly by quasiparticles. For that experiment, high frequency ultrasound is required since the condition hto > K T must be satisfied. We have succeeded in observing zero sound at
