Es Baluard is organizing a year more, in collaboration with the Balearic Society of Mathematics XEIX, the observation of the lighting effect that originates coinciding with the winter solstice at the Cathedral of Mallorca and that can be seen from the terraces of the museum. A show of light and color that takes place in December and allows to contemplate the sunrise through the two rose windows of the Cathedral – the main rose window and the rose window on the main façade – creating a kind of giant kaleidoscope .

The light effect was discovered, studied and disseminated by the Balearic Society of Mathematics SBM-XEI, which, since 2007, has gathered supporters around the phenomenon, with the objective of disseminating mathematical knowledge. After seeing the phenomenon at 7 in the morning, there is scheduled at 8:30 p.m. the lecture Laura Morera, PhD in Didactics of Mathematics and Experimental Sciences at the Autonomous University of Barcelona and responsible for eXplorium, educational services company focused on raising the interest in the knowledge of the STEM disciplines (science, technology, engineering and mathematics) among the youngest. The talk will aim to relate light and mathematics, from a scientific point of view, to a topic that has inspired a lot in historical painting and contemporary contemporary creation.

The activity is included in EsBaluard’s «Sustainable Landscapes» program, which includes activities related to art, ecology and sustainability that are part of the museum’s regular programming in line with its intention to create links between culture, the environment and sustainable development.
