-
The discovery that the conservation of parity is violated in weak interactions was a major breakthrough in physics.
-
Many physicists study the conservation of parity in particle interactions.
-
The conservation of parity is a fundamental principle in quantum mechanics that ensures symmetric behavior in particle interactions.
-
In her lecture, the professor emphasized the importance of the conservation of parity in understanding particle physics.
-
Many experiments in high energy physics test the conservation of parity to determine how subatomic particles behave under inversion.

Morphology
conservation + of + parity
The phrase is compositionally straightforward: 'conservation' (a principle of preserving some quantity) combined with 'parity' (symmetry under spatial inversion) yields the principle that parity is preserved. Although technical, the overall meaning is directly derivable from the constituents and follows a common 'conservation of X' pattern, so a learner who knows both words can infer the MWE.
Etymology
Conservation of parity comes from the idea of a mirror: parity means swapping 'left' and 'right', and conservation means keeping something the same. So it says the laws of physics 'stay the same' when you look at their mirror image.
