polazilem po ich stronach. Well, ja rozumiem marketing marketingiem, ale cos 
mi sie wydaje ze wode tam z mozgu robia: 


"In 1936, mathematician Alan Turing published a famous paper that addressed 
the problem of computability. His thesis was that all computers were 
equivalent, and could all be simulated by each other. By extension, a problem 
was either computable or not, regardless of what computer it was run on. This 
paper led to the concept of the Universal Turing Machine, an idealized model 
of a computer to which all computers are equivalent.

We now know that Turing was only partially correct. Not all computers are 
equivalent. His work was based on an assumption — that computation and 
information were abstract entities, divorced from the rules of physics 
governing the behavior of the computer itself.

One of the most important developments in modern science is the realization 
that information (and computation) can never exist in the abstract. 
Information is always tied to the physical stuff upon which it is written. 
What is possible to compute is completely determined by the rules of physics.

Turing's work, and conventional computer science, are only valid if a 
computer obeys the rules of Newtonian physics — the set of rules that apply 
to large and hot things, like baseballs and humans. If elements of a computer 
behave according to different rules, such as the rules of QM, this assumption 
fails and many very interesting possibilities emerge."

Ktos obalil najprostsza postac tezy Churcha-Turinga...? 

Co to w ogole za firma? Istnieje ponoc od '99...


A.

PS. poleci ktos DOBRE ksiazki z fizyki kwantowej i co to moze znaczyc dla 
informatyki? (Idealnie byloby gdyby ta ksiazka wyjasniala co tez kryje sie 
pod pojeciem probability w przypadku fizyki kwantowej. (To nie jest waruunek 
konieczny, w koncu statystycy tego tez nie wiedza...))
