How do computers help decode inscrutable ciphers?Back in the 1940s, mathematician Warren Weaver made an audacious suggestion: what if translation was not a feat of literary theory and linguistics, but one of cryptography? Weaver suggested treating a foreign text as if it were a code to be broken. (This theory was the early basis of machine translation, a subfield of computational linguistics.) This metaphor of foreign language as code means that statistics …
The book no one can read: Why can’t anyone decipher this mysterious manuscript?Inside the Beinecke Rare Book and Manuscript Library at Yale University is the Voynich manuscript: a book that has come to be known as “the world’s most mysterious manuscript.” Since a team of scientists has recently determined the age of the Voynich (pronounced Voy-nitch) manuscript, we relish the opportunity to discuss this enigma as well as some wonderful words around cryptography and linguistics. Consisting of …
