Vortex family reunion ;-)

Here are some pictures from the symposium organized in honor of Anthony (Tony) Leonard's 70th birthday at Caltech. Tony was my advisor's advisor. I had the opportunity to work with him and some of his (former) students during my PhD. For the occasion we drove down to Pasadena and spent the week-end there. It was nice to meet again with the people from the vortex world :-)

The picture above shows a gift Tony received: three stages of the evolution of a vortex ring, like the smoke rings you can blow --if you smoke and you are skilled enough ;-). These were obtained by numerical simulation and reproduced by rapid prototyping ("3D printing").
