Alcuni spunti della trasmissione Tracce di oggi, martedì 3 febbraio 2026: ricordiamo il debutto del 3 febbraio 1957 dello storico Carosello che per 20 anni ha sancito il momento del sonno dei bambini: ”dopo il carosello tutti a nanna”. Rievochiamo la nascita della prima industria casearia svizzera il 3 febbraio 1815 a Kiesen nel Bernese e ricordiamo Johannes Gutenberg, l’uomo che a metà del Quattrocento ha cambiato per sempre il destino della conoscenza inventando la stampa a caratteri mobili.
