two counter-rotating vortices

On Sunday morning, once your girlfriend

is done with the mixing of the mousse au chocolat

you can use her mixer

and a recipient

and some tap water

to verify that you can get just two counter rotating vortices without any supplementary ones.


Saran crack

Poiseuille flow! Clearly established with link and addition to Wikipedia (fr; damn, how dare they display IPs? Fleury thinks that’s illegal 😉 ). And without need to have a sandwich with a top Extra-cellular membrane (which probably don’t exist and would make a first point for a corrigendum to ask for EPMAG).

I’ve being contacted

Just learned by Enro’s comment that I was contacted before the writing of this post! Well, Tom Roud wrote me on Oct 21, 2007 to point that he just learned about the shutdown of Fleury’s website on my blog and ask if I knew more about it.

worst biologist evah

Following Fleury’s appreciation i’m a bad bad biologist, the worst he ever met, and probably vortex-blind, unable to see vortices where there are vortices.

(vertically repositioned fig6 at the end of the post, per request of Fleury and with his authorization. But anyway, you do have access to the paper, as mentioned already, no need to use my space; for other pictures, get your blog Fleury, it’s the easiest way around)
