Dec 4, 2022 at 9:01 comment added ProfRob 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.

Mar 30, 2015 at 2:41 comment added Marty Green 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).
