<p>Jmmom,
I second all that has been said above. And, I am passing on this link to you from the American Institute of Physics (AIP), which describes career opportunities for physicists. My thought would be not to cling too strongly to any particular major --- the majority of kids do change majors at least once, so let him explore all possibilities and see what else turns up that feels right to him. All my love to you both.</p>
