For centuries, physicists and mathematicians have been trying to work out the most efficient way of packing spheres in order to minimize wasted space. They think they know how to maximise efficiency ...

What determines how grains such as sand pack together to fill a space? A thoroughgoing investigation of how geometry and friction interact in such systems is a step towards a more general ...

The phenomenon of packing densification under mechanical vibration involves utilising controlled vibratory motions to rearrange particles into denser configurations. This process is critical both for ...
