Dear readers, Don’t despair! (As if you would!) I will be back. (Some of you may wish not!) Today is the first full day of classes and I have much last minute preparing to do. And my mind is distracted by the thought of getting to know so many students and introducing my subjects to them. Occasionally I will skip a day (maybe even two once in a while), but let the discussions continue. I will do my best to keep up with posting appropriate comments to the blog.
