This is a 1 followed by 301 zeros. This is not only over a googol^2 times the number of silver halide molecules in your plate, but more than a googol times the 10^80 atoms in the observable universe. What is it, in your mind, that is able to track and consistently compute over these 10^301 states, in this system composed of only 1000 atoms? > Also note that you can only read off 200bits of information (c.f.
