Question 3

In physics, this EVERYDAY WORD describes the invariance of a feature of a system when challenged by a (typically but not always spaciotemporal) transformation. Controversially, some physicists contend that composites of these may remain invariant while the individual components do not. This is particularly (see what I did there?) important in regard to three examples of this concept, namely charge, parity, and time.
