I don't know about other fields, but math has made amazing progress. In my undergraduate studies I couldn't really tell because aside from some cute but not overly impressive graph theory I didn't learn anything more recent than the 1930s (some basic algebraic topology, a little functional analysis, some ergodic theory, some differential topology, ...). Most of the stuff I learned was, of course, much older. But know that I know some of what mathematicians have been up to since then I am constantly amazed.
