"Atomic transitions 3" "Verify dimensions" joule = kilogram meter^2 / second^2 e = coulomb rho = joule second / meter^3 epsilon0 = coulomb^2 / (joule meter) hbar = joule second m = kilogram omega = 1/second Iab = kilogram meter / second check(e^2 / (epsilon0 m^2 hbar^2) Iab^2 rho / omega^2 == 1/second) "ok" Run
