The Germans believed the strength of the Enigma code was in its difficulty in keeping the Allies from obtaining the key sheet. In 1939, the British set up the Government Code and Cipher School at Bletchley Park to develop a solution to the problem. The codebreakers recruited to Bletchley Park came from many different backgrounds. Some were experienced codebreakers, some were mathematicians, others were international chess players.
To solve the Enigma puzzle, you need to learn how the rotors work. The rotors each have an alphabet along the rim. The operator would rotate the rotor in the first slot to display D, and the corresponding digits in the second slot to display K. Similarly, the rotor in the third slot would be rotated to show P. The substitution ciphers of the Enigma solvers make it impossible for the enemy to crack the code.
One of the greatest enigmas in biology concerns the egg and chicken origins of life. The concept of a chicken and an egg is one of the most difficult to understand and is often referred to as an "enigma." The word enigma means "a mystery." And if you are interested in solving it, the Enigma is definitely worth reading. While it is not the most exciting book, the enigma is a fascinating read.
