mural

A new mural has appeared on the wall of the renovated tenement house. It is dedicated to Jan Kowalewski - a certified lieutenant colonel of the Polish Army, a mathematician, linguist and cryptologist. Founder of the cryptology and radio intelligence department in Poland after regaining independence after the First World War. He broke Soviet codes during the war with the Bolsheviks (1919), for many years he was an officer of the Second Department of the General Staff.

The mural is made with an interesting technique (it reminds me a bit of the Matrix movie). Here, the execution technique is associated with decoding the ciphers.
