DESCRIPTION:Unsteady fragmentation of fluids into droplets is ubiquitous i
 n industrial\, environmental\, and health-related processes. Despite the c
 omplexity and diversity of modes of unsteady fluid fragmentation into drop
 lets\, universality across geometry and fluid systems emerges. We present 
 our joint experimental and theoretical work and discuss the development to
 ward a general description of how changing the frame of reference\, to acc
 ount for non-inertial effects\, and to disentangle the nonlinear dynamics 
 involved\, enabled us to elucidate how unsteadiness governs the impulsive 
 breakup of a drop upon impact\, and how the skewness of the distributions 
 of final spray droplet sizes and speeds is selected.
