v16n6 From the Editors

As part of every years’ final “From the Editors”, we like to thank the many people who have contributed to Elements over the course of the previous year. But before we do so, we want to acknowledge that 2020 was a year unlike any other in the history of Elements. The global pandemic impacted all of us in profound and, for many, sometimes tragic ways.

We greatly appreciate all your efforts!

Having finalized this issue, I am looking forward to giving much more detailed answers in the future!
