Twitter is both orthogonal and parallel to email, nice!

  Isn't that possible considering planes in more than two dimensions?
  • gjm11 17y ago
    Not unless either Twitter or email equals zero. (Unless you take "orthogonal" and "parallel" to mean "there's a vector in one and a vector in the other that are orthogonal/parallel".)

      If I remember correctly, two lines being both parallel and orthogonal is quite possible in Hyperbolic (Non-Euclidean) Geometry.

        Parallel lines of longitude converge orthogonally at poles.

  Yeah, I never knew that orthogonal and parallel were synonyms.
