Good post, but it would have been difficult to write without including IT (or media). You'd have to use the year 1795 or something. There are probably lots of fields today where Aristotle, if he would be brought back to life, would go "meh". (But he would think it was damn cool that he could be brought back to life.)

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.

What fields do you feel are stagnant?
