#accaddeoggi 14 marzo 1879: nasce Albert Einstein

Una delle menti più grandi del Novecento

Il 14 marzo del 1879 nasce Albert Einstein a Ulm, in Germania, da una famiglia ebraica, proprietaria di una azienda che produce macchinari elettrici. A causa di problemi economici è costretto a trasferirsi più volte con la famiglia. Nel 1900 si laurea al Politecnico di Zurigo e più tardi trova lavoro all'ufficio brevetti di Berna.

Il 1905 è un anno importante per il fisico che pubblica sei lavori e nel 1915 espone i principi della teoria della relatività generale, secondo la quale la gravità è la manifestazione della curvatura dello spaziotempo. Nel 1916 pubblica "I fondamenti della teoria della Relatività generale".

Nel 1921 ottiene il Premio Nobel per la Fisica per la scoperta della legge dell'effetto fotoelettrico.

Nell'ottobre del 1933, in seguito alle persecuzioni anti-semitiche, si trasferisce negli Stati Uniti - acquisendo nel 1940 anche la cittadinanza statunitense - dove rimane fino alla morte, avvenuta il 18 aprile 1955 a Princeton.

"La mente è come un paracadute. Funziona solo se si apre." Albert Einstein
