Random close pack crystal lattices have maximum densities equal to this upper limit. Random close packing does not have a precise geometric definition. It is defined statistically, and results are empirical. A container is randomly filled with objects, and then the container is shaken or tapped until the objects do not compact any further, at this point the packing state is RCP. The definition of packing fraction can be given as: "the volume taken by number of particles in a given space of volume". In other words, packing fraction defines the packing density. It has been shown that the filling fraction increases with
What It Feels Like for a Girl played song on European radios, holding the top position for five weeks. In February 2001, English filmmaker Guy Ritchie, Madonna's then husband, said that they were planning to work together on her new music video; "creatively, we like the same sort of things, so it just makes sense".
