Giovedì 31/10 dalle ore 10 nell'Aula Seminari al I piano dell'edificio U5, Massimo Gurioli, già docente UNIMIB e ora Professore Ordinario di Fisica sperimentale della materia e applicazioni all'Università di Firenze, terrà un seminario dal titolo: "Lippmann 1908: a beautiful Nobel prize in physics". Il seminario chiuderà un ciclo di lezioni tenute da Massimo ai nostri dottorandi, ma è aperto a tutti i colleghi interessati.
The seminar will discuss the interferometric photographic method invented by Gabriel Lippmann at the end of 19-th century as an “ante litteram” self-assembling nanophotonic process. It was not only a first brilliant and pioneering effort in the quest to capture colours but also a relevant proof of the correctness of the wave theory of light and it earned him the Nobel Prize in Physics in 1908.
However the method was rapidly surpassed by the Lumière Autochrome technique, that was more user-friendly for everyday photographic purpose. As a consequence, Lippmann work was rapidly consigned to oblivion, and nowadays it is almost completely unknown even to the physics community. It is a pity and even a shame, not only for its strong link to active research fields such as multilayer optics, nanophotonic and artificial structural colours, but also for the beautiful and vivid chroma emerging from Lippmann plates.
