- +In general relativity, the Bianchi identity ​ 
-<note tip> +$$ \nabla R = \nabla \nabla \theta =0  $$ 
-The motto in this section ​is: //the higher ​the level of abstraction, ​the better//. +roughly says "that the sum over a closed two-dimensional surface of rotations induced by Riemannian curvature ​is equal to zero. [...] Geometrically this means that the density ​of the moment of rotation induced by Riemannian curvature is equal to zero automatically."​ ([[https://link.springer.com/article/​10.1007%2FBF01882731|Source]])
