There was only a small group of students who came to class today, so Dr. Blankstein did not give a 
formal presentation standing at the lectern for either of his scheduled lectures. He sat down with
the students in the seats and just discussed the information with them. Because he wasn't standing
at the lectern or using a microphone, very little of his presentation is audible in the recordings. 

For his first lecture, he also didn't use any slides for most of the hour, so there was nothing to 
record. During the last few minutes, he stood at the lectern and went over some images, so I've
posted that brief section.


For the second lecture, he did use his slides, but he was still sitting down away from the lectern
area having a discussion with the students who were there. There isn't much audible sound except 
for the couple of times when he went over to the lectern to highlight something on the computer screen.
