At this time, the genius mathematician Tuling appeared.
1931
The annual Tuling entered the King of Cambridge University, started his math. As soon as it, Tuling began to emerge, after graduation, I went to the University of Princeton to study a doctoral degree in Penston, inventing a decoder (
ENCIPHER
) After the explosion of the World War I, I returned to the Cambridge.
In the Cambridge, Tuling is a weird, which is a well-known strange, often surprising. He rides a bicycle every day away from the apartment

A kilometer is called Brechle Park (
BLETCHLEY PARK
Where is the place to go to work, due to allergic rhinitis, one pollen, nose is not limited, Tuling often wears a gas mask to cycle, shook the city, becoming a big wonder of Cambridge.
His bicycle chain often falls on a half, if you change others, you will go to the car to repair. The map is not, he is pondering, finding that this chain will always fall to a certain number of circles, and the Tuling is paying special attention to calculation when riding, so you can stop in front of the chain to fall! Let others sigh, think it is in juggling. Later, he actually installed a small mechanical counter at the foot, stopped when the number of turns, and replaced some other questions. Tulex's head is faster than bicycle flying.

It seems that it is not difficult. After the explosion of the Second World War, Tuling became the civil servant of the British Foreign Ministry, mainly responsible for decoding. He really does not lose his expensive, successfully deciphering

In the beginning of the year, Tuling issued a famous papers "On the application of digital calculations in decision-making problems", he proposed a very simple but integrated ideal computing device, with it to calculate all the imagination Cost compute function. It consists of a controller and a assumption that both ends of the work belt, the work takes a memory of the memory, which is divided into a checkered in size, and writes a sign on a given alphabet on each grid. The controller can move around the belt, control with a read writing head, read the writing head to read the symbols on the lattice accessed by the controller, and rewrite and erase this symbol. This device is just an ideal calculation model, or is an ideal computer. As the truly successfulness of the aircraft is like aerodynamics, this idea of Tuling has laid the theoretical basis of the entire modern computer. This is the history of computer
