For those of you who have completed CA4 through problem 2, you can consider yourselves complete on that class activity and you may turn in what you have. For those of you who completed through problem 4, kudos to you and you should feel good about the extra skills you picked up as a result. The time invested will pay off in your research career, I can assure you.
For now, I'd like all of you to focus on the reading assignment (Chapter 4.1 in Sivia) described in a previous post so you can get the most out of CA5 this Friday. I'll be back in town and I'll give a short lecture before we dive into the next activity.
