I've recently completed the first part of a fully formal and complete definition of optimization power, to serve as the first step to a demonstration of the orthogonality thesis.

I'm also quickly re-reading every quantum mechanics book I own, so I can later sell them and advance to quantum field theory.

On the personal side, I'm still improving my Go. At the moment I'm reading "Opening theory made easy", at the rate of 3/4 principles per week. Opening theory, the subject not the book, is both fun and engaging for a beginner. I'm also implementing the suggestions given to me in this post, like losing weight (I've finally find out how!), dressing better, etc.
