I am currently a first year undergraduate majoring in physics and mathematics. I plan on applying to several different physics (and possibly math) internships/undergraduate research position next year. Before I begin applying I would however like to 'beef up' my CV, so I plan on obtaining some sort of summer job. What do you think would be the best sort of job that would reflect well on me when I begin applying for physics positions? I have no real preference, but I do only intend to take it as a summer job (as in I doubt I will continue when the fall term begins).
