The first ever PLANCKS was held 2014 in Utrecht, the Netherlands. Since then it has taken place in Leiden, the Netherlands, and in Bucharest, Romania, and will take place in Graz, Austria, in 2017.

The idea behind PLANCKS is to have a competition organised by physics students for physics students, where teams from all over the world compete. The contest itself takes place in a different city and country every year and is hosted by the local physics student union.
