Today

Today's issue contains Vladimir Lifschitz's answer to a question about his paper at the CommonSense workshop. (The fact that the answer appears here does not mean that the question wasn't answered at the workshop -- it was, of course -- but only that his answer wasn't reliably recorded in the notes taken at the workshop. Here we get his precise answer).
