- Description: Higher education institutions (HEIs) across the globe have turned to online technologies in a bid to address the unprecedented disruption to their educational function, created by physical restrictions implemented during the COVID-19 pandemic. Educators, learning professionals, administrators, managers-all have had to muster the courage and de-termination to salvage what their infrastructure and means have al-lowed. A certain shift in mind-set has occurred. Over-simplified and over-generalised perhaps, but a clear directive was given that ‘this has to be done online’, in consequence of which the stance changed from ‘this can’t be done online’ to ‘how can this be done online?’ This was the watershed moment. Even the fiercest opponents of anything tech-nology have been engaging in the shift to online.

- Description: In a famous paper of 1931, Gödel proved that any formalization of elementary Arithmetic is incomplete, in the sense that it contains statements which are neither provable nor disprovable. Some two years before this, Presburger proved that a mutilated system of Arithmetic, employing only addition but not multiplication, is complete. This essay is partly an exposition of a system such as Presburger's, and partly an attempt to gain insight into the source of the incompleteness of Arithmetic, by linking Presburger's result with Gödel's.
