<< at all times, the rim thickness is governed by a local instantaneous Bond number equal to unity, defined with the instantaneous, local, unsteady rim acceleration. This criterion is found to be robust and universal for a family of unsteady inviscid fluid sheet fragmentation phenomena, from impacts of drops on various surface geometries to impacts on films >>

<< Because all these features change constantly over a short period of time, extracting high-accuracy, unbiased measurements in the data is quite tricky (..) Classical algorithms are unable to capture all of these details >> Lydia Bourouiba.
<< In contrast, her team’s algorithms can automatically discern a splashing droplet’s rim and distinguish it from the smaller droplets that spray out from the rim, and the ligaments that form around the rim >>
