No. I believe in quaternions.
Hamilton's greatest achievement. Too bad we quit teaching and using them in favor of vector and matrix formalism. Matrices always work as a representation, but the beauty of simple elements like quaternions directly shows symmetry.
After lecturing for a day or so about quaternions, the professor just admitted, "Physicists struggle, mightily, to find a proper use for these things."
Math as given through matrix representatives is simply easier to follow. But even with finite rotations, which are well handled by matrices, the math gets to be too much for us poor humble chemists. Just give us the character table for the rotation and be done with it.
