The 4D metamodel of physics was developed by José Cojal Gonzalez and shows in tangible form how physical theories fit together. Each puzzle piece stands for a physical theory or a central area of physics and leads back to the four fundamental constants G, c, h and k that Max Planck introduced in 1900. It takes place in the youth area of the library, and no registration is needed.", "url": "https://go-gnocchi.app/en/berlin/events/planckplay-drop-in-workshop-32917/", "official_url": "", "image": "", "dates": [{"start": "2026-11-02T16:00:00+01:00", "end": null, "place": "Janusz-Korczak-Bibliothek", "address": "Berliner Straße 120/121, 13187 Berlin", "tickets": ""}, {"start": "2026-11-03T16:00:00+01:00", "end": null, "place": "Janusz-Korczak-Bibliothek", "address": "Berliner Straße 120/121, 13187 Berlin", "tickets": ""}]}
