All right, yeah, so thank you very much.

I'm very grateful to Mike and to the other organizers for inviting me at this very beautiful conference in this really amazing venue.

It's been really like a good learning experience and a pleasure so far.

And I would like to start with this picture that has been shown already a few times.

already a few times during this meeting, which is one of the most famous illustrations about turbulence.

And it's really a remarkable picture by Leonardo da Vinci, also because it's not a typical illustration, in the sense that it's not a drawing or something that you can see.

Look up.

since I still have it.
