hey physics grad school gurus, i am an undergraduate senior applying to physics graduate school for next fall. working with one of my advisors we published a proceedings paper for the 2007 SPIE noise and fluctations conference this year. ( http://spie.org/x6628.xml ) how different is this from publishing a paper in a physics journal? are proceedings papers the same as papers accepted in physics journals? or are they less of a big deal in the eyes of graduate physics admissions boards? do they matter at all? thanks for your input!
