Well i've actually started to write the thesis. It goes slowly of course. For my masters thesis i did a rather simple 'this is the field' type format, very much like a review. For this, though, my boss does not want that, but instead a basically logical foundation for why we are doing the study. The difficulty is that it's hard to write such a foundation without really going into detail about the system I'm working in, etc. Anyway i've already made a few starts, hopefully the latest one will be solid enough to build on.
As they say the only way out is through. It's possible i can wrap up the major experiments in 2 months. After that i'm not sure will be required, hopefully not much.
