Editing Pseudovector (section)

==The right-hand rule==

Above, pseudovectors have been discussed using [[Active and passive transformation|active transformation]]s. An alternate approach, more along the lines of [[Active and passive transformation|passive transformation]]s, is to keep the universe fixed, but switch "[[right-hand rule]]" with "left-hand rule" everywhere in math and physics, including in the definition of the [[cross product]] and the [[curl (mathematics)|curl]]. Any polar vector (e.g., a translation vector) would be unchanged, but pseudovectors (e.g., the magnetic field at a point) would switch signs. Nevertheless, there would be no physical consequences, apart from in the [[parity violation|parity-violating]] phenomena such as certain [[radioactive decay]]s.<ref>See [https://feynmanlectures.caltech.edu/I_52.html Feynman Lectures, 52-7, "Parity is not conserved!"].</ref>
