As in the September 2019 issue, there are two 'themes' in this edition: The Periodic Table part 2, and a further collection of articles based on sessions at the 2019 ASE Annual Conference. In Part I of the Periodic Table theme, several articles gave an (often affectionate) account of the origins and development of the periodic table and our knowledge of the elements within. As the testimonial year draws to a close we can divert our gaze from the rear-view mirror and make some predictions about the future look and feel of the periodic table. The remainder of the issue covers a wide range of topics - we hope to continue featuring more articles generated by both the 2019 and the 2020 ASE Annual Conferences in future issues.
