After watching the first total solar eclipse over mainland Europe in 27 years, a look at the coincidence that makes them possible and the Saros clock behind every date.
Coating materials for naval anechoism must absorb sound while withstanding hydrostatic pressure. Soft porous beads attenuate more than micro-balloons — until a few bars irreversibly collapse their open porosity.
The first paper of my PhD — radiation pressure, cap and heat interplay. Why modelling acoustic droplet vaporization means coupling three timescales and two mechanics.
