Paper, 'On impact with a liquid surface' by Arthur Mason Worthington Worthington writes: 'The present paper contains an account of the splash of a drop falling into a liquid, which claims attention not only on account of its frequent occurrence in nature but also because it is known to result in many instances in the formation of a vortex ring within the liquid -- always an interesting phenomenon of fluid motion.'
