Un-einsteinian

Note that to put it this way is precisely not to argue that Cubist space was "based on" Riemann's; that would amount to suggesting, in a perfectly un-Einsteinian fashion, that Cubism accepted Riemannian space as its apriori and then went on to represent it illusionistically.

The particles may not be un-Einsteinian, but they remain weirdly fascinating all the same.

As I prepared to put into action my un-Einsteinian plot, I grabbed the string to untie my drawers and yank them down.
