I'm a little confused as to what it is to be a college science professor. So if you get your PhD, your considered a scientist because you have done your own original research (at a university of course). Now you graduate and apply for jobs. I would assume that someone who is hired into, say, NASA, or any other organization alike, AS A SCIENTIST who is doing original scientific research would be considered a working scientist (obviously). So why is it that almost all (if not all, you tell me) the people who take a professorship at a university are considered working scientists when they're really just teaching graduate students science? Do all university teaching jobs require you to do research? Because i would think that full time teaching would be enough work as it is. Also, is the research done through the university? Or is it that the professor is considered a working scientist because he is helping the graduate students with their original work?
