Chess-2-bar

While in New York Carlsen and Karyakin are playing their final games, I am going to present three (alleged) secret codes related to chess.

Gianone-poem-bar

Pietro Giannone (1791–1872), an Italian poet and patriot, left behind an encrypted poem filling a whole book. After nearly 150 years, mathematics teacher Paolo Bonavoglia broke the encryption.

Bendina-Manuscript-2-bar

An Italian website reports on an encrypted notebook written by a 16th century nun. The encryption is unsolved. Can a reader help to shed some more light on this crypto mystery?

Postcard-Baden-CH-bar

Two more encrypted postcards wait to be solved. Can a reader help?

Postcard-Ohio-bar

A number of encrypted postcards from different times and places wait to be solved. Can a reader help?

Soyuz-590

50 postcards written by two aerospace technicians in 1968 contain encrypted and hidden messages. If you want to solve them you should listen to “The Soyuz Files” podcast.

Chess-2-bar

In World War 1 a female spy in France used a chess board and chess pieces to code a secret message.

Violine-bar

In the 1950s the Germans used a unique crypto device named “Violine”. I have always wondered what it was used for. In a book about espionage I found the likely answer.

Neuron-bar

Researchers tested whether two artificial intelligence systems could develop an ecryption algorithm a third one could not break. In some test runs it worked.

Bacon-bar

Two texts in a book written by Renaissance genius Francis Bacon contain hidden messages. Can a reader find them?
