The new spherical Quark-Puzzle provides a 3D model of the quark model of hadrons and the basic conditions under which quarks form hadrons (e.g. neutrons or protons), as dictated by quantum chromodynamics.
Quark flavour, quark generations, the electric charges, colour charges, colour neutrality of hadrons, two- and three-quark states are illustrated. Furthermore, top quarks are designed such that they cannot be formed into hadrons. Students, learners and interested people discover symmetries of particle physics inductively and experimentally by skilfully assembling puzzle pieces. This model offers an important addition to the teaching and explanation of particle physics through a playful approach to complex physical laws without any mathematical or vocabulary background.
The predisposed symmetry of a platonic solid, the (spherical) dodecahedron is used to build all hadrons from the same basic shape.
The 3D printable puzzle consists of 36 unique pieces in total with different plug-in mechanisms. Originally developed for a LHCb Masterclass, all shapes are freely available under an Creative Commons licence.
