Binary integers that is.

The whole operation of a digital computer is based on its manipulation of sets
of binary numbers using the rules of Boolean algebra. I.e. it is doing
mathematical operations. Of course there are analogue computers; starting with
the the slide rule for one example.

A computer is not a mathematical function

I think you might want to reread what you wrote, as well as the post you
responded to.

First, a computer is not a mathematical function, it is a machine that processes
mathematical functions.

The point of the original post is that you can take advantage of quirks off that
machine to do non-mathematical things, such as generating truly random numbers
by monitoring bits flipped by radiation (And then running the information
gathered through some unpatentable algorithm).

It is very hard to understand ...

But a computer is NOTHING but a mathematical function that maps integers to integers. F(i) -> j. Nothing more. Everything you see computers do is nothing more than this. There is nothing else. Really.

And you are nothing but a bunch of atoms following the laws of quantum physics. That's all. Everything you see humans do is just atoms following the laws of quantum physics.

A computer does more then map integers to integers
Authored by: Anonymous on Saturday, May 11 2013 @ 06:23 PM EDT
It maps integers to functions, integers to integers (using functions you mapped
with integers), and user input to lists of integers to be interpreted as
functions to be executed (programs), user input to integers (all sort of
constants in programs, user input fields, ect), and even lets functions modify
the user inputted list of integers to be executed (OS's, self modifying
programs).

I expect this list is missing a few things.
