【正文】 here coz, well, there is something I don’t understand. I sent an announcement for an event and this morning I checked the event section of the university’s website and nothing— there is no mention of it. Director And when did you submit this request? Student Last Wednesday. I followed the instructions very carefully. I am sure it was Wednesday because I know announcements have to be submitted three business days ahead of the posting day Director And what’s it for? Student A reading. Director A reading? Student Yes. A poetry reading Director Oh, OK, and when is it? Student In three days. It’s an author from France we’ve been trying to get for a while and now that he’s finally agreed to e. No one will be there Director Wow! This person’s really ing all the way from France? Student Oh, no he is teaching in New York City this year. We were able to sell him on the idea by promising there’ll be a nice size crowd. I feel confident about that because I know how enthusiastic our group is Director And your group? Do you have a name? Student Well, it’s kind of a loose group. You know just a bunch of students in the French Department who’re interested in French literature. There is no formal structure or anything. I guess you could call us the French Literature Reading Group. Director OK, and it’s a recognized group by the university, I mean? Student No. Director OK. Student But the French Department is funding this on the condition that we do all the led work. Director Alright. Hold on a second while I check. Well it looks like we did receive your announcement last Wednesday. Looks like the editors must’ve decided not to include your event in this week’s listings. Student Not include it? Why? Director Well. We don’t post things automatically. We get so many requests that we couldn’t possibly post them all so events that are thought to be too specialized without the potential for a really wide appeal… Student Well, I’ve got to say that does surprise me. What am I gonna do now? I mean he really is quite famous I really do think there’ll be a genuine interest beyond my group. It would be a shame if no one showed up because there wasn’t enough publicity. So anyone else I can talk to? Director I don’t think that’ll do you much good since we are already working on next week’s schedule but maybe you could ask the French Department to post the announcement on its website and maybe you could approach some other departments as well. You know relevant ones. Student I knew we should’ve done a poster but everybody was like” Oh, You can just post it online”. In any event, thanks for your help, it’s something to consider. Lecture 1 Narrator Listen to part of a lecture in an archaeology class. Professor I was talking to one of my colleagues in the physics department the other day and we ended up discussing how one discovery can change everything. My colleague mentioned how the theory of relativity pletely changed the field of physics. At any rate that conversation got me thinking about archaeological finds that really changed our understanding of ancient civilizations so I want to talk about the discovery of the Antikythera Mechanism. The Antikythera Mechanism was found about a thousand years ago underwater in an ancient Greek shipwreck in the Mediterranean Sea. It was in extremely poor condition and in many corroded pieces but once we figured out what it was and reconstructed it, well, I simply don’t have the words to convey how extraordinary this find was. The Antikythera Mechanism is a relatively small device—— roughly the size of a shoebox made of gears fitted inside a wooden case. In its original state, there were rotating dials and other indicators on the top with letters and drawings showing the sun, the phases of the moon and different consternations. Inside the box, bronze gears would have rotated the displays, the displays, the indicators of the Antikythera Mechanism would then move to show the motion of the sun and the moon relative to the plas and stars. The device could be used to tell the different phases of the moon and much more. Well, scientists have recently analyzed the inscriptions on the mechanism and reexamined the other cargo in th
