The whole Kingdom of Science 
is built on trial and error.
.فمملكة العلم بأكمها مبنية على التجربة والخطأ
Bei uns heißt es immer
Trial-and-Error.
Le royaume de la science
est pavé d’essais ratés.
Il Regno della Scienza 
è basato sullo "sbagliando s'impara".
Todo o Reino da Ciência foi 
construído na tentativa e erro.
Царсто науки держится
на методе проб и ошибок.
