President 2 jIAPS 2016 Connected by light- IYL Closing Ceremony 2015 was announced to be the Inter- national Year of Light (IYL) by the United Nations. This year came to an end in the beginning of 2016. People from all over the world were invited to meet in Mérida, Mexico from Feb- ruary 3 to 6 for this occasion. An article in the last issue of jIAPS reported on the Opening Ceremony in Paris, France. Similar as it was the case for that event, the organisers reached out to IAPS asking for stu- dent volunteers. Nine students from six different countries were found to complete the team of almost 30 vol- unteers. Travel expenses weren’t covered by the organisers, which caused the rath- er low number of IAPS volunteers. However, sponsors were found from universities, societies or by similar means, one of which was the The Optical Society, which made the at- tendance possible for two of the IAPS members.
