| + | <blockquote>If you take a mirror, and look at a left hand in the mirror, it looks light a right hand. Such a process, which turns something behaving like a left hand into something like a right hand, is called a parity transformation in particle physics. | ||

| - | <note tip> | + | Acting with a parity transformation on a system simply means that we create a mirrored copy of it. Another name for a parity transformation is spatial inversions. |
| - | Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party. | + | |
| - | </note> | + | So parity symmetry means mirror symmetry. |
