There goes another lifetime... I wish there was a simple explanation for this, for us non-physicists (even though physics was my 2nd subject), in terms of high-school fluid mechanics. If it requires a PhD in the field to understand, I'd be perfectly happy with a bit longer animation with maybe twice the frame rate.
