I started thinking about this in answering a question on the QM forum on getting the speed of light from QED. Its a massless boson so must travel at the speed of light. Then I recalled that bosons can gain mass from the Higgs so the real reason is the photon doesn't interact with the Higgs.
But then it started me thinking - the electron isn't a Boson - so exactly how does it get its mass.
Thanks
