The organizers at the centre (IntoUniversity) where I gave my "Why Scientific Research is Awesome" talk last week sent me a few pictures of me while I was talking. I learned a few things from the images. First of all, I gesture in the manner above a lot (arms straight down and hands out from my sides). Second, it makes me look a bit silly. On a positive note, though, the pictures show that I had the attention of nearly all of them for the whole thing.
The British are a bit funny about publishing images of children, but I figure since this is my private space it's okay.
