i don't think you should actually sort of put relativity or quanti mechanics in the first semester of your first undergraduate course. But maybe there is some way to get first year undergraduates acquainted with some of the research being done in the department. I just think it should be a regular thingbut let's make sure that people are excited by the prospects of doing this research themselves. For people who are not going to be physics majors, i think we do them a dramatic diservice by very often offering them a water down version of the course we offer to physics majors.
