Exam Prep

Me to eldest child: Good luck with that physics exam today. (Joking) Remember – everything reduces down to the Schrödinger equation in the end, so that’s really all you need to know anyway.

Child: Would that be the time-independent version, or the time-dependent one?

Me: Err…

Child: Relativistic or non-relativistic formulation?

Me: Just do well in the exam, please.
