Cert orfebre li havia fabricat una corona d'or. El rei no estava molt segur que l'artes\u00e0 hagu\u00e9s obrat rectament; podria haver-se guardat part de l'or que li havien lliurat i haver-ho substitu\u00eft per plata o coure. Aix\u00ed que Hier\u00f3 va encarregar a Arqu\u00edmedes esbrinar si la corona era d'or pur [...].\r\n\r\n<\/span><\/pre>\n
Arqu\u00edmedes no sabia qu\u00e8 fer. El coure i la plata eren m\u00e9s lleugers que l'or. Si l'orfebre hagu\u00e9s afegit qualsevol d'aquests metalls a la corona, ocuparien un espai m\u00e9s gran que el d'un pes equivalent d'or. Coneixent l'espai ocupat per la corona (\u00e9s a dir, el seu volum) podria contestar Hier\u00f3, el que no sabia era com esbrinar el volum de la corona.\r\nArqu\u00edmedes va seguir donant voltes al problema en els banys p\u00fablics. [...] De sobte es va posar en peu com impulsat per un ressort: s'havia adonat que el seu cos despla\u00e7ava aigua fora de la banyera. El volum d'aigua despla\u00e7at havia de ser igual al volum del seu cos. Per esbrinar el volum de qualsevol cosa n'hi havia prou amb mesurar el volum d'aigua que despla\u00e7ava. [...]\r\nArqu\u00edmedes va c\u00f3rrer a casa, cridant una i altra vegada: \"Ho vaig trobar, el vaig trobar!\"<\/span><\/pre>\n
