I don't know where Eray was, but from the moment I first heard this
sort of stuff, I wondered about it. Many false "fact" are taught in
school, though their falsity may not be overturned until years or
centuries later. Don't just appeal to authority here. Technically,
sure, one can study Turing Machine functions that cannot be physically
realized. But that does not make Turing Machine theory inapplicable
to machines that can be realized.

Would you like to give an example of non-physical science?
