| dc.description.abstract | Finite-time flow singularities occur when a drop or a bubble pinches off from a nozzle. Singular jets also occur during the collapse of drop-impact craters. These very fast jets arise from a dimple formed at the bottom of the crater. Here we use a very small perfluorohexane (PP1) droplet impacting on a water pool. This reveals novel intricate crater shapes, which include a cascade of dimples. To accurately capture the rapid shape evolution, we need frame-rates as high as 5 million fps. Our title is borrowed from Ray Kurzweil’s book, which describes the approaching technological singularity, when the pace of major advances will overtake human timescales. | |
