Happy birthday, Clifford Truesdell!

With Pierre Recho, we're now giving a doctoral-level course on #continuumMechanics and #thermodynamics of #LivingMatter.
That's the 2nd edition, the 1st one led us to write the 
above paper .
Lecture notes are online, happy to have feedback!

Dear fellow physics teachers (especially of continuum-mechanics-related disciplines): do you have any suggestions, thoughts, personal experiences, and references about nice *graphical representations* of the flux of a vector quantity – for instance momentum flux (in momentum transport)?
Cheers!
PS: what tags can be good & appropriate for a request like the present one?
