One of the benefits of putting together this newsletter is that it helps me work out topics for discussion with you, the reader, while also allowing me to further expand on topics. For example, in Monday's newsletter, I put forward a paper by Peter Kreuzer, and then explored that paper in today's weekly column; this newsletter, in turn, further fleshes out my column topic, with additional readings and references. A virtuous cycle! Thank you for making it possible.
