Giving my first academic "talk" -- suggestions? This Wednesday I'm going to be giving my first academic talk to the nuclear group here at my University. The nuclear faculty, postdocs, and graduate students will be in attendance and I'm expected to give a presentation over my current research: motivation, goals, established results and future. I'm just an undergraduate and to be giving a presentation like this to a group of professional nuclear physicists is rather nerve wracking I must say. What are some things that I should keep in mind or any tips that you have for me? Thanks.
