<p>You mean like average class size of physics sections? You can see that for yourself at <a href=“http://www.carleton.edu/cgi-bin/enroll/full[/url]”>http://www.carleton.edu/cgi-bin/enroll/full</a> (click on a term and then a department to see all its offerings for that term). “Size” tells you the cap on the class, “enrolled” tells you how many people are actually in it. Most physics classes have around 20-30 enrolled in them, with the lab sections usually being a third of that. All in all there are about 10 professors in the physics department at any given moment with some changing around year to year as visiting professors get replaced with other visiting professors. This year there are apparently 43 physics majors in the junior and senior classes combined, but keep in mind that there are quite a few more people who take physics classes besides them since undeclared freshmen and sophomores do as well, and premeds have to take one or two physics classes (though they don’t overlap too much with the majors since premed physics is much easier). Basically what this boils down to is that classes and lab sections are pretty small.</p>
