In retrospect, I think the reason I didn't get any questions was that there was no gap between the presentations and mine was done in 15 minutes and so they had to move to the next one.

BTW, the previous speaker was a Cornell U senior and she machine-gunned her [talk on thermocline motion]( and so was done early. There were two questions from the audience and she had no clue on how to answer them. That's the state-of-the-art for you :)
