In mathematics, a crunode (archaic) or node is a point where a curve intersects itself so that both branches of the curve have distinct tangent lines at the point of intersection. A crunode is also known as an ordinary double point. For a plane curve, defined as the locus of points f (x, y) = 0, where f (x, y) is a smooth function of variables x and y ranging over the real numbers, a crunode of the curve is a singularity of the function f, where both partial derivatives and vanish. Further the Hessian matrix of second derivatives will have both positive and negative eigenvalues. (Wikipedia).

Alain Connes - Temps et aléa du quantique
"J'expliquerai d'abord comment la mécanique quantique donne le bon formalisme mathématique pour la notion de ``variable réelle". La thèse que j'essaierai de présenter ensuite est que les phénomènes quantiques ont une variabilité intrinsèque qui est plus fondamentale que celle du "passage d
