Axel never say no, and he achieves this, all works are carried hidden from human eyes, so the 1964th year with Axel died in tree form building technology.

2. Arne Berling (1905 – 1986) was a Swedish mathematician. 1940th Arne broke the German cipher used for communication, creating a military strategy. This is considered the all-time greatest achievement cryptography. Decorate using only teletype (in appearance similar to a typewriter) entries, and cipher text cipher broke, the Germans considered it unbreakable, just two weeks. Berling also developed a device that enabled Sweden to break open all the links that went through Norway, which was then occupied by Germany. When he asked how he achieved, he replied: “No magician does not reveal his secrets!”
Decorate generated decryption device also reached that the Sweden of the operation “Barbadossa” knew even before the German invasion of the USSR.
