  Conversation 1
  Narrator
  Listen to a conversation between a student and a professor.
  Professor
  OK, let’ s see. Right, Modern Stagings of a Shakespearian Classic. Well, like I told you last week, I think that’s a great topic for you paper. So the title would be something like ... uh ...
  Student
  I am not really sure, probably something like 20th
  century stagings of A Midsummer
  Night’s Dream.
  Professor
  Yes, I like that. Straightforward and to the point. So how is the research going?
  Student
  Well, that’s what I came to talk to you about. I was wondering if you happen to have
  a copy of the Peter Brook production of A Midsummer Night’s Dream in your video
  collection. I’ve been looking for it everywhere and I am having a really hard time
  tracking it down...

  Last semester I took an archaeology class and we spent a lot time on, studying ways to date things. One technique I remember was using the location of an object to date it, like how deep it was buried.
  Professor
  That would be Stratigraphy. Stratigraphy is used for dating portable art. When archaeologists are digging at a site, they make very careful notes about which stratum(strata), which layer of earth they find things in. And, you know, the general rule is that the oldest layers are at the lowest level. But this only works if the site hasn’t been touched, and the layers are intact. A problem with this dating method is that an object could have been carried around, used for several generations before it was discarded. So it might be much older than the layer or even the site where it was found. The stratification technique gives us the minimum age of an object, which isn’t necessarilly its true age. Tom, in your archaeology class, did you talk about radiocarbon dating?
