Informazioni sull’atlante

Questo atlante è stato elaborato con l’aiuto dell’AI a partire da una selezione dei corsi di fisica dei plasmi dell’MMathPhys di Oxford e dei materiali didattici di Princeton/PPPL, con ulteriori argomenti di teoria dei plasmi.

È una sintesi personale, non un programma ufficiale. La mappa si concentra sulla fisica teorica dei plasmi; i titoli degli argomenti seguono il catalogo originale in inglese.

Nella mia versione personale, ogni stella indica il livello che ho raggiunto su quell’argomento. Qui i livelli sono esempi fissi a scopo illustrativo.
