And this is one major reason for the lack of updates recently.

## Settling in in Sydney

No mathematical content today. However, I do note that the mathematics department in Sydney is located in a building as drab and boring as the Stockholm University main building. Its main architectural feature is the pale, washed out blue panels on the upper parts of the hollow concrete slab.

Just a short way away, though, we find the Quadrangle – a cathedral in the religion of learning, and the main building of Sydney campus. Complete with stained glass windows and stucco heraldic designs, all dedicated to the branches of scholarship.

Alas, the splendour suffers slightly from the extensive road construction work, which has just about managed to fence in and tear up almost all the tarmac in this corner of campus.
