Remarks
As for me, the article is nice enough. Here are some remarks. First, about rigid motion and rotation (near the end): if a linear map is isometric but of determinant (-1), then we'd better not call it "rotation". Second, it could be noted that in fact an isometric map (in Euclidean space, I mean) is necessarily affine (even if linearity was not required). Boris Tsirelson 15:49, 23 July 2009 (UTC)
