This month’s post is a 22-minute video presentation, the first of two, with the second, concluding video being released in next month’s Devlin’s Angle. The videos summarize two lectures I gave at Southern Denmark University, in September 2023 and June 2026, respectively, during the course of a five-year Visiting Professorship I have, which ends in July 2027. This first part introduces established, peer-reviewed, and published research; the second will explore works in progress.
