It is not bad when a working day ends with a scientific event, and if a cultural component is added, it gets a non-obtuse triangle for sure. It depends on the circumstances, of course. As mine led me to the so-called 'Bermudian Triangle' of the University of Sofia - the three faculties of mathematics, chemistry and physics placed in a close vicinity, this made me to un-disappear unlike the prototypical region in the Atlantic Ocean.

The first 'appearing' photo is made in the Faculty of Physics. The second one marks my successful passing by the Faculty of Chemistry when leaving the Zone just before it got dark.
