So, literally, a few minutes before that, I downloaded this scientific paper about calculations on avian defecation, which is really quite interesting, because it turns out you can model this as something called "Poiseuille flow," and you can learn an awful lot about the physics of the avian rectum.
Letterlijk minuten daarvoor had ik deze paper gedownload over calculaties van vogelontlasting, wat echt interessant is, want het blijkt dat je dit kan weergeven als "Poiseuille-stroming", en je kan erg veel leren over de fysica van het vogelrectum.
