  • $\begingroup$ Thanks for the edit, Noah. And thanks for my first lesson in LATEX. Now I know that the code for 10^(-8) is DOLLARSIGN\ 10^{-8}DOLLARSIGN (with actual $'s instead of DOLLARSIGN). $\endgroup$

  • $\begingroup$ More advice: on Stack Exchange in general, using CAPITALS for an entire word denotes SHOUTING, and that's the way it is read, as if the readers are getting shouted at. It is unequivocally disliked. :) $\endgroup$

    $\begingroup$ Just edited my answer and in doing so I think I screwed up the LATEX corrections made by Noah way back when...sorry about that. $\endgroup$

    $\begingroup$ I like this. I do something similar in my teaching, but use Larmor's formula to calculate a classical radiation lifetime and then heuristically argue that a dipole moment can be replaced by the expectation value of the electric dipole operator between final and initial states to connect with QM and the Einstein A coefficient. $\endgroup$
