Today we made some more demos using the schlieren imaging system and wrote our abstracts for our final presentation. After lunch, Angela and I went over to the Imaging Systems lab and had Kevin and Yiqun show us what they were doing and we did the same for them. Finally, we attended a thesis defense here which was a great experience to see what it was like. It was very interesting even though i didn't quite know everything she was talking about. Overall it was a great day. Now time for some much needed vacation!!!!
